市政排水管道安全文明生产环保措施（Municipal drainage pipeline; safety; civilized production; environmental protection measures） Related measures, engineering quality control The quality control of 1. construction materials Many municipal sewer problems more than in the pipe quality, some pipes originally crack, impermeability of compression capacity is weak and other issues, the project after the completion of easy water leakage. To ensure the quality of the project, should choose the regular manufacturers of pipe into the pipe before construction, construction site must sampling, inspection report of mechanical test tubes and strict verification certificate data, check the pipe appearance, found peeling, breakage, crack, honeycomb, explicit phenomenon shall put into use, to ensure the quality of pipe. Quality control of stage 2. trench excavation Should the production safety and engineering quality is determined considering the excavation section, the bottom of the tank, the tank bottom width, excavation depth, slope and other factors as the main basis for determining the slotted section, to ensure scientific and reasonable slotting; both scientific and economic slope sloping roadbed, ensure smooth and safe construction; if the construction site not affect the slope or the slope does not meet the requirements for the construction safety, we need to do pit supporting. In the process of excavation, with excavator surface broken asphalt layer and subgrade slag layer, excavated after a certain distance, to be on the bottom elevation measurement strictly control, special attention is not the top super trench bottom, if overbreak should be carefully backfilling, avoid the use of tamping rubbish and silt soil, humus inconsistent standards the soil at the bottom, eliminate low injection appeared the phenomenon of water intake. 3. level quality control in the construction of base seat Trench excavation acceptance, can according to the design drawings on the tube base to start construction.
