He has standardized Code for Acceptance of Construction Quality of Building Water Supply, Drainage and Heating Engineering (GB 50242-2002).
Rain pollution belongs to rain pollution pipe network project!
Pipe network engineering includes power supply pipeline, rainwater pipeline, sewage pipeline, water supply pipeline, fire pipeline, gas pipeline, communication pipeline, intelligent pipeline in residential area and other projects. Pipe network engineering refers to the design of various pipe networks, most of which belong to municipal pipe network engineering. Various buildings, structures, equipment, etc. Institutions established within the planning and construction scope of cities and towns (townships) to provide paid or unpaid public goods and services to residents based on government responsibilities and obligations.
design requirements
In order to ensure the normal operation, fire demand and maintenance management of the water supply network, it is necessary to install various necessary accessories on the network, such as installing valves and fire hydrants at appropriate positions, installing exhaust valves at the high places of the pipeline, and installing drainage valves at the low places of the pipeline. There are various ancillary structures on the pipeline network, such as pipeline foundation, pier, valve well, inverted siphon pipeline, pipe bridge and so on. In order to regulate the flow in the water supply network and reduce the construction cost and operation cost of the network, regulating structures such as clear water tank, pressurized pumping station, water tower and highland pool are often set up.
In the total investment of water supply project, the cost of water supply pipe network accounts for more than 70%. In order to reduce investment, save energy and ensure safe water supply, it is necessary to calculate and compare various schemes.
