Abstract

The invention relates to the field of underground pressure drainage, and particularly relates to an underground pressure drainage system. The underground pressure drainage system comprises a submersible sewage pump, a water level switch, a drainage pipeline, a filter screen cover, an anti-blocking check valve and a controller, wherein the submersible sewage pump is arranged at the bottom of a deep foundation pit and comprises a water pumping opening and a drainage opening; the water level switch is connected with the submersible sewage pump; the drainage pipeline is connected with the drainage opening and comprises a vertical pumping section for connecting the drainage opening to the ground surface and a transverse drainage section outside the ground surface; the filter screen cover is arranged on the water pumping opening; the anti-blocking check valve is arranged in the vertical pumping section; an opening is formed in the side wall of the anti-blocking check valve and forms a cleaning opening easy to open; and the controller is connected with the submersible sewage pump, a contact switch, the anti-blocking check valve and the water level switch. The submersible sewage pump is protected by transferring the position where silt is accumulated and blocking large sundries, the silt is separated, and accumulation of the silt in the drainage pipeline is reduced; and by arranging the cleaning opening, the anti-blocking check valve which is mainly blocked can rapidly remove blockage, blockage is reduced, and maintenance is convenient.

Description

technical field [0001] The invention relates to the field of underground pressure drainage, more specifically, to an underground pressure drainage system. Background technique [0002] Deep foundation pit is a temporary structure in the process of building construction, and it has greater risks due to the small safety reserve. In the process of excavating deep foundation pits, drainage and anti-irrigation is a very important safety guarantee measure in underground construction, and it is a link that runs through the entire deep foundation pit operation process. Deep foundation pits will continue to be affected by various types of water, the most common being the infiltration of underground aquifers and the invasion of rainwater, and the rise of water levels in deep foundation pits caused by these various forms is difficult to control from the root. Under the influence of different geological, hydrological and climatic conditions, the drainage operation is mainly carried out...
