Time flies, and a short time has passed. A period of work has ended. After this period of hard work, we have made greater progress in our continuous growth. It's time to sum up our past achievements in the work summary. So how is the general work summary written? The following is a summary of the personal work of road and bridge technicians that I have compiled for you. Welcome to reading. I hope you will like it.
Summary of personal work of road and bridge technicians 1 My name is xxx and I work in your company. On the xxx project. Time flies, time flies. In a blink of an eye, 20xx years have passed and we have ushered in a brand-new year. In this project, I took the post of technician and engaged in technical work. I summed up this year's work in 20xx, and talked about my understanding of technical work from a personal point of view.
As an engineer, we should make a good plan in our work and arrange each working procedure and production factors reasonably. Do a good job in manpower, materials, equipment, technical preparation, peripheral relations and so on required for subsequent projects in advance. Ensure that the follow-up work is not in a hurry, and there is no shortage of east and west, which will not affect the quality, safety and progress of the construction period. Report the problems that need to be solved and improved in the construction in time, and ask the supervision engineer to sign all kinds of internal page materials and engineering quantity confirmation materials formed in the construction process in time to avoid affecting the later measurement.
The ultimate goal of an enterprise is to make a profit, so on the premise of providing qualified products, we should pursue the maximization of benefits. This battle.
In the new year, I will do my job well as always. There is no end to learning, so you should study harder in your major. Improve your professional skills and management ability, and do your bit for the company.

3. In charge of the construction management of A02 contract section of Nanning Outer Ring Expressway, with total length of19.36km and total length of four bridges of1028m. ..
After 16 years of working practice, we have made some achievements and accumulated a lot of valuable experience. The following is a summary of my professional and technical work as a road and bridge engineer, which is convenient for review and organization.
A, technical preparation before construction
The preparation work before construction of each project generally includes the blue prints.the design, the preparation of construction organization design and technical disclosure before construction. First, be familiar with the technical documents, design drawings, technical specifications and technical requirements of this project, summarize and report the problems existing in the drawings in time, and ask for assistance in solving them. Investigate and inspect the site, understand the actual geological, topographic, hydrological and climatic characteristics of the site, find out the technical points and technical difficulties, and then formulate feasible construction organization design according to the construction tasks. Technical guidance and disclosure (construction technical standards, quality control, construction operation procedures, construction technology, construction safety, quality inspection, etc.). ) to the construction personnel, so that the construction personnel are familiar with the engineering situation, design intent, requirements, quality standards and construction methods, so that the project can proceed smoothly.
Second, the general situation of construction
Measurement is a very important work, and it is the most basic and key means to control geometric dimensions. The consequences caused by measurement deviation are often not ordinary quality defects, but mostly serious quality accidents.
Every time the project comes into the site, according to the traverse points and leveling points provided by the owner or the design department, the retest and encryption work will be carried out. Traverse and leveling should be carried out according to the requirements of engineering technical grade and specification. According to the actual terrain conditions and construction needs, add encrypted traverse points and leveling points to form attached traverse or closed traverse and attached leveling line or closed leveling line, so that the data accuracy of traverse points and leveling points can meet the specifications and construction requirements. For special structures and special parts of the project, triangulation or traverse network control should be set up according to the requirements of construction specifications to ensure the construction of structures (large and medium-sized bridges, etc.). ).
Plane position and elevation of subgrade, structure and protection works during construction. It should be completely controlled, and provide construction data for on-site construction personnel and necessary measurement data for quality inspection and testing personnel. When filling and excavating subgrade, the trench excavation line, slope toe filling line and platform position should be laid out according to the actual situation, and the technical parameters such as mileage pile number and elevation should be marked with obvious signs; In bridge and culvert construction, according to the plane position and relative relationship of the structure, the center position and longitudinal and transverse axes of the structure are set out. In order to prevent the measurement error, the observation procedure of one-method measurement and multi-method review should be carried out during lofting, and the review should be carried out from different traverse control points. If the measurement deviation is beyond the scope of construction measurement error, it should be carefully summarized, find out the reason of deviation, re-lofting, and make measurement records. After the data is confirmed, technical disclosure shall be made to the site construction personnel.
Third, the test work
Test work is the basic work to ensure engineering quality, and it is also an important content of construction site management. Responsible for inspection, appraisal and acceptance of whether the materials used in the project meet the requirements of specifications and design regulations, and responsible for various raw material tests and mix design. Responsible for the process control in the construction process.
Before starting work, each test instrument and test equipment shall be tested according to the corresponding regulations. If the performance declines, it should be adjusted in time. If the required accuracy cannot be achieved after adjustment, it should be reported to the superior and sent to the designated place for maintenance. After the repair,
After metrological verification, corresponding identification shall be affixed, and records shall be made, and the accounting of testing instruments and equipment shall be established and properly classified and kept. Do a good job of testing raw materials such as soil, cement, steel bars, sand and gravel, and do a good job of concrete mixture ratio test and mortar mixture ratio test to prepare for construction.
In the process of construction, in accordance with the construction specifications and technical standards stipulated in the contract, in strict accordance with the relevant test procedures and methods, do a good job in various tests, fill in test records and test reports in time, and strengthen quality control in construction. Often go to the construction site for sampling inspection, do a good job in the test section, designate a representative filling section as the test section, do a good job in the compaction degree and water content test, carefully check the loose laying thickness of the filler and the corresponding rolling times, make records, calculate and determine the loose laying coefficient of the filler, so as to guide the whole filling construction.
After receiving the field test task, take active actions to complete the task with high quality and high efficiency, observe and record various situations in the test process in detail, report in time when finding abnormal phenomena or test results that do not meet the design requirements, and take effective treatment measures to solve them as soon as possible to ensure that the construction is not delayed and the quality of each process of each project meets the specified requirements. Any process that has not been inspected and tested, or that fails to pass the inspection and test, or that fails to pass the revision or revision, cannot be transferred to the next process.
Fourth, the site construction organization
Responsible for the organization, arrangement and coordination of the project site construction plan. Seriously study and understand the relevant contract documents, technical specifications, procedures and construction technology management system issued by superiors, be familiar with and understand the bidding documents, check the design drawings and quantities, draw detailed drawings and auxiliary construction drawings, provide the material use plan of the project, fill in the original construction records of the project in charge, and provide accurate original data for engineers and technicians.
Before construction, inspect the construction site to understand the local hydrology and climate, arrange and guide drainage when the construction site is in place, and combine it with permanent drainage facilities. The discharged rainwater shall not flow into farmland and cultivated land, and shall not cause ditch siltation and subgrade erosion. According to the construction plan, arrange team construction tasks, and make on-site technical disclosure to the teams or labor teams under their jurisdiction, such as the general situation of the project, construction process, technical standards, construction methods, key working procedures of special structures, safety measures, etc. In the process of construction, adhere to the first line of construction and take ultimate responsibility for quality.
During subgrade construction, pay attention to the shaping and compaction of the slope in the filling section to ensure the stability of the slope. Construction should be completed before the rainy season as far as possible. If the construction conditions are not met, temporary waterproof and drainage measures should be taken. Subgrade filling should be transported with excavation, paved with pressure. The soil transported to the site by car should be paved as soon as possible and evenly according to the boundary width of the filled soil determined by the surveyor. Loose laying thickness should meet the specified requirements. If possible, roughly calculate the unloading distance according to the layer width, layer thickness and the loading amount of the dump truck, draw the grid of filling with white ash, and designate a special person to command the truck to unload the soil within the specified range. 2-4% cross slope should be made on the surface of each layer of filled soil to facilitate drainage. Before rain and before work, compact loose soil to avoid water accumulation. When rolling subgrade, follow the operation procedure of "first static, then moving, first fast, then slow, first edge, then middle". If springs or fish scales appear on the subgrade surface, they should be treated locally and re-rolled. After the completion of rolling, notify the tester to conduct on-site test and inspection. After passing the inspection, clean up the site and prepare for the lower filling construction. During the construction of cutting excavation, the ditch should be cut off before cutting excavation to prevent a large amount of surface water from directly scouring the excavated slope and causing the slope to collapse. During excavation, according to the excavation line data provided by surveyors, obvious signs (such as making slope frames) are erected to direct the manipulator to operate, so that the excavation interface can be put in place at one time and the slope can be formed at one time, which reduces the waste of manpower and material resources and provides convenience for the protection engineering construction. With the excavation of cutting, according to the arrangement and classification of steps, the skeleton of slope protection and grass planting protection can be protected in time, which can not only use the construction access road of subgrade as a transportation channel, reduce the workload of manual handling, but also avoid long untreated slopes.
In bridge construction, we should pay attention to the implementation of engineering technical quality and safety assurance measures, establish the guiding ideology of "prevention first, control in advance", conduct all-round inspection and guidance on key projects and concealed projects under construction, ensure quality and construction safety, and reduce and put an end to major accidents. Such as digging pile construction, when the pile site is rich in surface water and there is a lot of water seepage in the hole, the hole wall support should be strengthened in time to prevent the hole from collapsing due to water seepage in the shaft wall. If the seepage level is high, try to use open ditch to intercept it; When the water level is low, the well point method is used to reduce the groundwater level, and several holes in the same row of piers are excavated at the same time. The hole with large water seepage is arranged to be excavated in advance for centralized drainage to reduce the water level of other pile holes, which is beneficial to construction. Pay attention to safe operation, check whether the on-site supervisors wear helmets and safety ropes, and set up shelters when necessary; Carry out regular inspection, command, supervision and maintenance of the bucket, hook wire rope, hoist and other machines and tools for extracting soil and stone slag. When installing and pouring wellhead casing or retaining wall, it should be 20~30cm above the ground to prevent debris from rolling into the hole and injuring people. When the digging operation is suspended, the orifice shall be covered with a hole cover and clearly marked with obvious signs to prevent accidents. Check the carbon dioxide content regularly before and during digging. When the carbon dioxide exceeds the standard or the hole depth exceeds 10m, use a blower for ventilation to ensure the safety of underground operation. If blasting is needed in the hole, shallow hole blasting method should be adopted and support should be strengthened. After blasting, use an exhaust fan to exhaust smoke, and check that it is non-toxic before underground operation. Educate operators on safety awareness and safety technology, arrange on-site duty, check and handle, clean up and report abnormal situations in time, and assist in research and handling. After the hole reaches the design depth, the bottom of the hole should be treated, and the disturbed soft layers such as loose slag, silt and sediment should be cleaned, inspected and accepted, and the reinforcement cage should be made and concrete poured, and then the next working procedure should be started. During pier construction, attention should be paid to the checking calculation of formwork support to ensure that the formwork and support have sufficient strength and rigidity and are not deformed during construction. Construction joint treatment should be carried out in strict accordance with the construction specifications. In the construction of superstructure, special attention should be paid to the stability checking of high-supported beams and bridge erecting machines. For cast-in-place beams, attention should be paid to foundation treatment and preloading observation to ensure the stability of bearing settlement. In the process of construction, it should be carried out in strict accordance with the construction specifications to ensure that the project is "external reality and internal beauty".
V. Engineering Survey and Interior Information
Engineering survey plays a very important role in the project implementation process. Only by mastering the contract documents, project bidding documents and detailed rules for measurement and payment of bill of quantities, and measuring the completed quantities in time, can the capital turnover meet the needs of the project progress and realize a virtuous circle.
Summary of personal work of road and bridge technicians 3 My name is xx, and I work in xxxx Company. In a blink of an eye, 2008 passed and we ushered in a brand-new year. In 2008, I led new technicians to engage in technical work and participated in the' management' of the project. I have worked in xx project, xx project, xx project and xx project successively. Summarize the work in the past year and talk about the understanding of technical work from a personal point of view.
Engaged in technical work, we must first have an attitude of being good at learning and studying. We are engaged in the bridge reinforcement industry, and the bridge structure and reinforcement scheme are different, so there is no ready-made experience to learn from. This requires a detailed study of the drawings in advance, as close as possible to the reality when preparing the construction plan, and an understanding of the whole construction process and various matters needing attention in your mind.
As an engineer, we should make a good plan in our work and arrange each working procedure and production factors reasonably. Do a good job in manpower, materials, equipment, technical preparation, peripheral relations and so on required for subsequent projects in advance. Ensure that when the follow-up work is implemented, there is no hurry, no shortage of east and west, and the construction period will not be affected.
At work, personal work attitude is also very important, and the tasks assigned by the leaders must be completed as required, and cannot be delayed or perfunctory. Special circumstances can not be completed on time, should be reported in a timely manner. Convenient to solve the problem as soon as possible.
The work of technicians is also hard. During the day, they have to climb up and down the construction site to guide the construction, and at night, they have to sort out the inner pages of the day and arrange the work for the next day. This requires a hard-working spirit, and the work of the day is completed on the same day, and it will never be put off until the next day.
Technicians work in the construction line and are responsible for the quality, safety and progress in the construction process. Timely report the problems that need to be solved and improved in the construction, and put forward solutions to the leaders. In the work, we should deal with the relationship with the construction personnel and the supervision owner, and everything is based on ensuring the progress, quality and safety.
All kinds of internal page data and quantity confirmation data formed in the construction process shall be signed by the supervision engineer in time, so as not to affect the later measurement.
The ultimate goal of an enterprise is to make a profit, so on the premise of providing qualified products, we should pursue the maximization of benefits. This requires reasonable arrangement of construction technology, working procedure, manpower, mechanical equipment and material plan in the construction, so as to reduce the project cost as much as possible under the premise of ensuring the progress and quality. At the same time, pay attention to saving manpower and materials in the construction process. For the changes that can be added, we should strive for them from the supervisor and the owner in time.
In the new year, I will, as always, do my job well, participate in project management, improve my professional skills and management ability, and do my bit for the company.
