The invention discloses a foundation pit drainage device with a quick sand prevention function for civil engineering. The foundation pit drainage device with the quick sand prevention function for thecivil engineering comprises a motor, a motor seat, a main shaft, bearings, upper sealing rings, springs, a turbine, a shell and lower sealing rings. Compared with the prior art, the sealing performance is kept through the springs and the upper sealing rings, and elasticity of the springs can enable the upper sealing rings to be always attached to the turbine and kept tightness with the turbine; and meanwhile, the lower sealing rings are adopted to seal the position between a water inlet and a water outlet of the turbine, so that water flow keeps pressure in a turbine cabin, quick sand is further prevented from existing in the gap of the turbine, the maintenance probability of the drainage device is reduced, and the popularization and application value is achieved.
Description
technical field [0001] The invention relates to civil engineering equipment, in particular to a foundation pit drainage device for civil engineering with the function of preventing quicksand. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to the relevant construction regulations. For those with deep excavation and nearby buildings, the foundation pit wall support method, shotcrete retaining wall method, and large foundation pit even adopt methods such as underground diaphragm wall and column-type bored pile inter...
