I. Overview of the Project
The slope is a rock slope (concrete slope), the slope is stable, the rock structure on the slope is well developed or slightly weathered, and the slope ratio is 1: 1 ~ 1: 0.3.
Second, the slope greening construction methods, technical measures and construction equipment
1, construction technology
The greening technology of rock slope adopts the patented technology of Three Gorges University: vegetation concrete slope protection greening technology, and has applied for four national technology patents. It has obtained three patent certificates and is widely used in Gaobazhou, Geheyan, Three Gorges, Jiangsu, Shandong, Hunan, Yunnan, Sichuan and other places with more than 300,000 square meters.
2. Selection of grass species
The mixed formula of grass seeds is: grass bermudagrass _ _%, Eragrostis curvifolia _ _%, perennial ryegrass _ _%, alfalfa _ _%, Caragana korshinskii _ _% and Lespedeza _ _%.
Bermuda grass is a perennial herb and belongs to warm season lawn. Grass has stolons and rhizomes, which have the advantages of fast propagation, strong growth potential, easy turf formation in a short time, slender leaves, low pruning resistance, strong adaptability, salt tolerance, trampling resistance and extensive maintenance and management.
Eragrostis curvata: Warm-season grass, clustered, with slender leaves, developed roots, up to 90㎝, and strong cold resistance and drought resistance.
Perennial Lolium perenne: cool-season grass, overgrown with weeds, overwintering safely at the low temperature of -30℃, with fast planting speed and strong pest resistance, which can quickly cover the slope and provide a good growth environment for other plants.
Alfalfa: It is a straight-rooted plant, with developed taproots and the characteristics of nodule growth. It can fix nitrogen in the air, resist drought, cold and barren soil, improve soil physical and chemical properties, improve soil fertility, form stolons and produce beautiful purple florets.
The mixed sowing combination is suitable for the temperature and climate in the construction area, and has strong characteristics of soil conservation, slope protection and sand fixation. Mix cold and warm seasons to ensure the slope is stable and green.

Third, measures to ensure project quality
1, and establish a complete quality management system.
Project intends to set up engineering department and central laboratory, responsible for quality work. Each construction team has a quality inspection team, equipped with full-time quality inspectors, and each construction site also has part-time quality inspectors, forming a three-level quality management network. Carry out quality education for all employees, link the project quality with wages, and formulate reward and punishment regulations. That is, according to the construction quality of each subdivisional work, each department of the project intends to set up quality awards with clear rewards and punishments. There is no direct connection between the funds of the first-level quality control personnel and the inspected department, which improves the relative independence of quality control work.
The engineering department and the central laboratory work under the leadership of the chief engineer. The main scope of supervision and inspection is as follows:
(1) Whether the quality and specifications of various materials are qualified;
(2) Whether the construction technology and operation method of subdivisional work conform to the specifications;
(3) Whether the project quality meets the requirements of technical specifications, unqualified projects will not be accepted, and resolutely "start a new stove";
(4) Whether the original records are timely, accurate and complete;
(5) Regularly check whether the performance of various construction machinery is in good condition;
(6) Whether the measurement and test are correct and conform to the specifications;
(7) Whether the implementation of TQC is serious and whether effective measures are taken for weak links;
(8) Whether the construction personnel hold the work license to prevent the construction from escaping;
2. Establish a quality responsibility system
Formulate the quality responsibility system of all departments and posts, so that the responsibility lies with people. Establish the quality objectives of each sub-project for management. The builder of each subsection shall be responsible for the construction quality of the subsection; The person in charge of each construction team shall be responsible for the construction quality of each bid section in the work area where the team is located; The project managers of all departments should be responsible for all kinds of engineering quality of the whole project in charge. In this way, it is implemented layer by layer and the quality management system is straightened out.
3. Carry out quality education and technical training.
Organize the personnel engaged in this contract to learn technical specifications and do a good job in quality education. New workers must receive on-the-job training, and overstocked posts must be certified. Always publicize and clarify the importance of engineering quality, so that all employees can establish the view of "quality first, owner first, prevention first, and speak with data".
4. Establish a central laboratory.
Set up a central laboratory in the project management department. The central laboratory is equipped with instruments and equipment for routine geotechnical test, concrete test, mixture ratio and other complex tests to meet the test service of this project. The central laboratory is equipped with testing engineer who has both theory and practice and experience, and two assistants testing engineer who work under the supervision of engineers. In addition, the central laboratory also fully implements the inspection and quality control of raw materials or test pieces used in the project.
5. Establish the technical disclosure system before construction.
Before construction, please ask the design representative to make disclosure, and put forward unknown or unclear technical problems in the construction drawing, so as to facilitate future construction. Before each subdivisional work starts, the construction personnel shall be disclosed according to the construction organization plan approved by the supervision engineer, and the construction shall be carried out in strict accordance with the construction organization plan to ensure the project quality.
6, adopt the project list system.
The purpose is to strengthen the responsibility, clarify the scope, promote contact and facilitate supervision.
(1) List the person in charge of the project, the person in charge of production, technology, quality control and test, and the supervisors stationed at all levels in the joint management department and the headquarters of each construction group;
(2) List the quality standards and statistical data of main materials and processes;
7, to carry out quality appraisal activities, the implementation of quality award.
The construction team under the project management department will hold a mobile red flag competition with subsection construction as the unit, which will be assessed once a month, with quality, progress and safety as the main assessment contents, and reward the units that have won the red flag. At ordinary times, engineers and technicians should often go deep into the site to track the quality.
Check, supervise and correct in time when problems are found, and ensure the engineering quality. And according to the quality tracking inspection, do a good job of quality award evaluation basis, the implementation of high quality and good price award.
