Municipal roads, water supply and drainage industry data are divided into technical data and security data.
The guarantee materials include: factory certificates (appearance certificates) of various raw materials, inspection documents and inspection test data (entrusted by quality supervision stations for inspection), raw material inspection sheets, inspection sheets for mechanical equipment entering and leaving the site, etc.
Technical data include: commencement report, construction organization design, record of joint review of drawings, record of measurement and recheck, record of positioning and setting out, record of technical disclosure of each process, record of inspection application, quality evaluation of process, inspection and acceptance of concealed works, quality evaluation of engineering parts/divisions, quality evaluation of unit projects, completion inspection application, completion report and completion summary, etc. (If filing is required, filing forms for each sectional project and the whole unit project are also required).
The working procedures of urban road engineering are roughly divided into: subgrade, road bed, lime-soil base, cement stabilized macadam base, asphalt synchronous macadam, adhesive layer asphalt, asphalt concrete and so on. (The sidewalk includes: subgrade, lime soil, concrete cushion, mortar and pavement), in addition, there are curbs and side flat stones. (Subgrade, lime soil and water stability need to be tested for compactness, lime content for lime soil, cement content and mixture ratio for water stability, and asphalt concrete needs to be tested for asphalt-aggregate ratio, mixture ratio and asphalt quality. )
The technological process of water supply and drainage pipeline can be roughly divided into: trench excavation, gravel cushion, concrete foundation, pipeline installation, edge wrapping (concrete flat pipe), concrete corner protection, manhole masonry and layered backfill. (Concrete pipes need to be destructively tested to detect the strength of concrete and the type and quantity of steel bars. Materials used for pipelines, such as bricks, sand, pebbles, steel bars and cement, are used for raw material tests, and mortar and concrete are entrusted for mixture ratio tests. After the pipeline is completed, functional tests are required, that is, closed water tests or pressure tests).
Street lamp engineering can be roughly divided into: trench excavation, lamp pier installation, lamp pole installation, cable sleeve installation, cable laying, lamp installation, transformer installation and debugging, etc. (Cables, lamps and transformers shall have corresponding quality certificates. )
Its structure is similar to the data sorting process of pumping station and also similar to civil engineering data.
That's all I know. Please correct me if there is anything wrong. I hope it works for you!
