Drainage system for lowering anti-floating water level for prevention of up-floating

Abstract

The invention relates to a dewatering and drainage system, in particular to the dewatering and drainage system for underground construction. The purpose is to provide the dewatering and drainage system that can drain water above the drainage level, and can automatically drain water when the water is higher than the warning water level. The system comprises a water collection tank, a pressure-resistant bin, a honeycomb duct, a drain valve, a water level observation hole, a decompression pipe and an exhaust pipe, wherein the water collection tank is lower than a drainage plane; the pressure-resistant bin is arranged as a closed tank, the bottom part is arranged in the water collection tank to be communicated with the water collection tank, and the upper part extends out of the drainage plane; one end of the honeycomb duct extends into the pressure-resistant bin, and the other end extends out of the drainage plane and is a certain height higher than the drainage plane; the drain valve isarranged at the bottom of the honeycomb duct, and higher than the drainage plane; the water level observation hole is formed in the honeycomb duct; the decompression pipe and the honeycomb duct are communicated and arranged in parallel, and an outlet extends to a drainage ditch; and the exhaust pipe is arranged at the upper end of the honeycomb duct. The dewatering and drainage system is simple instructure, solves major problems, fundamentally solves the drainage problem of underground buildings such as basements and underground garages when the water level rises, and avoids the situation that the basements and the underground garages are flooded, and only water pumping can solve the problem.

Description

technical field [0001] The invention relates to a drainage system for lowering the anti-floating water level, in particular to a drainage system for lowering the anti-floating water level for underground buildings. Background technique [0002] With the development of the economy and the increase of urban population density, the development and application of underground space is becoming more and more extensive, especially in geological conditions with poor water permeability such as rocks, muddy soil, and clayey soil, and the anti-floating water level is relatively low. The high underground space structure, the anti-floating problem of this kind of building is becoming more and more prominent, and affected by the wet season, as well as the short-term heavy precipitation, the groundwater level rises, and the drainage is not timely during the construction process, resulting in the raft foundation in the water. Floating under the action of buoyancy, uplifts and cracks appear ...

[0002] With the development of the economy and the increase of urban population density, the development and application of underground space is becoming more and more extensive, especially in geological conditions with poor water permeability such as rocks, muddy soil, and clayey soil, and the anti-floating water level is relatively low. The high underground space structure, the anti-floating problem of this kind of building is becoming more and more prominent, and affected by the flood season, as well as the short-term heavy precipitation, the groundwater level rises, and the drainage is not timely during the construction process, resulting in the raft foundation under the water. Floating under the action of buoyancy, bulges and cracks appear on the bottom plate, water seepage occurs, and the underground structure is seriously damaged, affecting the normal use of the underground structure
