[0016] The process based on the construction of storm sewer pipes includes the following steps:
[0017] (1) Surveying and setting out: the construction survey uses the total station wire to measure and set out, and the level is used to measure the height. During the construction, the elevation of the water surface is strictly controlled to maintain the direction of the water flow and the connection with the cross structure;
[0018] (2) Trench excavation: The excavation of the trench is excavated by excavator and manual excavation method. Mechanical excavation is carried out to 0.3 meters above the design elevation, and the remaining part is excavated manually. The width of the excavation groove bottom should meet the specifications If the excavation depth is less than 5 meters, use slope excavation. When the excavation depth is greater than 5 meters, support measures should be taken, or steps should be left in layers for slope excavation. The edge of the trench should not be...
