The invention provides a pneumatic precipitation construction method, which relates to the technical field of building construction and comprises the following steps: measuring and positioning; drilling and positioning; digging a mud pit; drilling well; lowering a pipe and filling; washing the well; high-pressure gas generated by a screw air compressor of the pneumatic precipitation equipment is stored in a gas storage tank after being dried by a drying machine and then is distributed into each automatic control system through a gas distribution assembly, a pressure adjusting device is adjusted according to the depth of a precipitation well, and the gas subjected to pressure adjustment is distributed into each water-gas replacement system; and the water-gas replacement system utilizes high-pressure gas as power to discharge collected water in the dewatering well. The pneumatic precipitation construction method is adopted, no electric equipment is arranged in the precipitation well, and safety and reliability are achieved; the air pipes are used for replacing cables in the rainfall process, and safety and neatness are achieved; automatic control is achieved, water is pumped immediately, stopping is achieved immediately when no water exists, and energy conservation and environment protection are achieved; the lift and the water yield can be adjusted, the function is powerful, and the adaptability is high.
Description
technical field [0001] The invention belongs to the technical field of building construction, and specifically provides a pneumatic precipitation construction method. Background technique [0002] With the gradual increase of various large-scale buildings, the excavation area of large-scale foundation pits is large, the excavation depth is large, the groundwater system is rich, the construction of foundation and foundation engineering is difficult, the cost is high, and the safety and reliability of the foundation are affected by the ground. Larger buildings have a greater impact. [0003] During the construction of the foundation pit, the method of water-stop curtain is often used to stop the water of the foundation pit. However, in the actual construction process, due to factors such as geological conditions, construction technology and depth of the foundation pit, the water-stop curtain often has the risk of local leakage. , and as the depth of the foundation pit incre...
