The inspection lot capacity 1 is the main engineering quantity of the current construction section. The concrete realization is that the inspection lot capacity is cubic meters when concrete is poured, and the inspection lot capacity is "T" when steel bars are installed.
2 The capacity of the inspection lot is the construction scope of the current construction period, which can be understood as the horizontal projection area of the current construction period. Specifically, the inspection lot is "O" in the process of concrete pouring, steel bar installation and formwork installation.
3. The inspection lot capacity refers to the quantity of work currently under construction. Specifically, the inspection lot capacity is the "root" when pouring concrete for frame columns and the "inch" when installing doors and windows.
Question 2: Does "one" in the inspection lot of retaining wall count as settlement joint? Is the "one" in the inspection lot of retaining wall a settlement joint?
Is it called one between two seams or one according to the specified meter?
Answer: the inspection lot of retaining wall is an inspection lot according to a settlement joint, which means one here.
Question 3: Is the municipal retaining wall an accessory project of the road? What is division and subdivision? Can you give me a copy of the acceptance information of the retaining wall? Large retaining wall can be accepted as a municipal unit project.
General retaining wall, as a branch project of municipal road unit project, does not belong to the subsidiary engineering branch.
Sub-projects are divided into cast-in-place reinforced concrete retaining walls, assembled reinforced concrete retaining walls, masonry retaining walls and reinforced retaining walls.
Subdivided into
Foundation, foundation, wall (reinforcement, formwork, concrete), drainage hole of filter layer, backfill soil, cap stone, railing (corresponding to cast-in-place reinforced concrete retaining wall section); Precast retaining wall slab, foundation, foundation (reinforcement, formwork, concrete), wallboard installation, drainage hole of filter layer, backfill soil, cap stone and railing (corresponding to the subsection of assembled reinforced concrete retaining wall);
Foundation, foundation (reinforcement, formwork, concrete), wall masonry, drainage hole of filter layer, backfill soil, cap stone, railing (corresponding to masonry retaining wall sub-division);
Foundation, foundation (reinforcement, formwork, concrete), installation of reinforced retaining wall blocks and reinforcement, drainage holes of filter layer, backfill soil, cap stones and railings (corresponding to the sub-division of masonry retaining wall)
I made it with data software, but you can't open it when I send it to you.
Question 4: How many meters of road is the basis of an inspection lot?
Code for Construction and Quality Acceptance of Urban Road Engineering (CJJ 1-2008) stipulates that the division of inspection lots is generally based on this provision and combined with the actual inspection needs. Complex projects or cement pavements can be divided in detail for inspection. Because the length of highway engineering is relatively long, it can be decided after consultation with the supervisor according to the specifications.
18 project quality and completion acceptance
18.0. 1 Before the project starts, the construction unit shall, together with the construction unit and the supervision engineer, confirm the unit (sub-unit) project, division (sub-division) project, sub-project and inspection lot that constitute the construction project, as the basis for the project quality inspection and acceptance, and shall meet the following requirements:
1 Each independent contract determined in the bidding documents of the construction unit is a unit project.
When the contract documents contain multiple project connotations, or the project scale is large, or it is composed of multiple independent designs, it is appropriate to divide the unit project into several sub-unit projects according to the project location or quantity and each independent design.
2. Units (sub-units) shall be divided into subdivisional works according to the structural parts or features, functions and quantities of the project.
When a branch project is large in scale or complex, it is divided into several sub-branch projects according to the material types, process characteristics and construction methods.
3 Division projects can be composed of one or several sub-projects, which should be divided into sub-projects according to the main types of work, materials and construction technology.
4 subdivisional work can be composed of one or several inspection lots. The inspection lot shall be divided according to the needs of construction, quality control and professional acceptance. According to the actual needs of urban road construction, all regions should designate appropriate inspection lots.
5 The corresponding subdivisional work and inspection lot of each division (sub-division) project shall be executed according to table 18.0. 1. Matters not specified in this specification shall be determined by the construction unit in conjunction with the construction unit and supervision engineer before construction.
