Foundation pit gushing water treatment structure applied to water-rich stratum and river supply

Abstract

The utility model discloses a foundation pit gushing water treatment structure applied to water-rich stratum and river supply. The foundation pit gushing water treatment structure comprises a drainage well. The drainage wells are arranged in deep well holes formed by drilling holes in the bottom end of the foundation pit, the multiple deep well holes are arranged in an array mode in the length and width directions of the foundation pit, each drainage well comprises a well pipe, a water suction pump and a water suction pipe, a water drainage opening of each water suction pump communicates with a water inlet of the corresponding water suction pipe, and a drainage opening of each water suction pump communicates with a water outlet of the corresponding water suction pipe. A water outlet of the water pumping pipe is arranged above the top end of the well pipe, a plurality of through holes are formed in the peripheral wall of the well pipe, the diameter of the cross section of the well pipe is smaller than that of the cross section of the deep well hole, and the well pipe and the deep well hole are coaxially arranged; the height of the well casing is larger than that of the deep well hole. According to the utility model, the technical problems of quicksand and piping phenomena of the foundation pit and instability of the foundation pit caused by heavy rainfall and strong drainage in the technical fields of emergency rescue of the foundation pit and engineering reinforcement are solved.
