Abstract

The invention discloses an efficient discharging device for building foundation pit dewatering, and relates to the technical field of buildings. The efficient discharging device comprises a foundation pit body, a driving device is fixedly connected with one side of the top of the foundation pit body, a screw rod is rotatably connected with one side of the driving device, and a limiting seat is fixedly connected with the other side of the top of the foundation pit body. When a driving motor is started, a driving rod is driven to rotate, a rotating disc and a rotating plate rotate at the same time, a rotating column continuously makes contact with an arc-shaped hole when rotating along with the rotating plate, the rotating column continuously rotates to push the rotating plate to rotate, the rotating plate rotates and drives a connecting sleeve and a water suction head to rotate, when the water suction head rotates, the water flow speed around the water suction head is conveniently increased, rapid water suction is convenient, and the drainage efficiency is improved; and when the driving device drives the screw rod to rotate, the other side of the screw rod rotates on the limiting seat, a threaded sleeve block moves along with rotation of the screw rod, a telescopic piece, a sleeve, a hollow fixing pipe, a rotating mechanism, a connecting sleeve and the water suction head can conveniently move at the same time, the water suction range is wide, and the water suction effect is better.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a high-efficiency discharge device for precipitation in a construction foundation pit. Background technique [0002] Building foundation pit dewatering means that when the building foundation pit is excavated, the groundwater level is higher than the excavation bottom, and the groundwater will continue to seep into the pit. Precipitation work due to bottom uplift, pit bottom piping and foundation bearing capacity drop. [0003] A kind of dewatering device for building foundation pit as disclosed in Chinese patent CN211571759U uses when there is water in the building foundation pit, the first drainage pump is turned on in time to drain water to avoid excessive water flow; when the rainy season, the groundwater level is higher, the first The communication pipe is connected between the drainage well and the building foundation pit to discharge a large amount of water in time. ...
