Water-carrying floating-reducing and floating-resisting system and basement structure

Abstract

The invention discloses a water-carrying floating-reducing and floating-resisting system and a basement structure. The water-carrying floating-reducing and floating-resisting system comprises a reservoir, a water inlet pipe and a water outlet pipe. The reservoir is provided with a water inlet, a water outlet and an air vent communicating with outside air; the water inlet pipe is used for communicating a water catchment system with the reservoir, and the reservoir is arranged higher than the water catchment system, so that water in the water catchment system overcomes self gravity through the water inlet pipe to flow into the reservoir; and the water outlet pipe is used for communicating a drainage system with the reservoir. The reservoir is arranged above the catchment system, the reservoir is arranged at a position with a certain height so that the height of an underground water head can be maintained below the reservoir, underground water with the height of the underground water head larger than the height of the reservoir is drained through the drainage system, the dead weight of the building can offset buoyancy of the underground water between the reservoir and the catchment system, the requirement for the drainage system is lowered, and drainage cost is reduced. The basement structure can control the height of the underground water head to be below the height of the reservoir all the time.

Description

technical field [0001] The invention relates to the field of basement drainage, in particular to a water-carrying buoyancy-reducing and anti-floating system and a basement structure. Background technique [0002] In the southeastern coastal areas of my country, due to the high groundwater level, buildings usually need anti-floating design. The commonly used anti-floating methods include: anti-lift pile method, drainage and decompression method, and self-weight increase method. Among them, the uplift pile method is the most widely used, but it also has the disadvantages of high cost and long construction period. In order to save investment and improve construction efficiency, many technicians have carried out innovative research on drainage and decompression methods in recent years. In the traditional drainage and decompression method, there is a water-stop curtain around the underground structure, and several sumps are arranged under the bottom plate of the underground stru...

Problems solved by technology

Since the sump is set under the basement floor, the groundwater in the basement is introduced into the sump through the catchment structure and discharged to control the groundwater head below the basement floor, which does not play the role of the building's own weight, and is located The groundwater in the basement is all imported into the sump through the water catchment structure, the inflow flow is relatively large, the requirements for drainage parts are high, and the drainage cost is relatively high
