Pressure-releasing structure of basement anti-floating plate and construction method thereof

Abstract

The invention discloses a pressure-releasing structure of a basement anti-floating plate and a construction method thereof. The pressure-releasing structure comprises a cushion layer and a basement bottom plate on the cushion layer, wherein water-collecting pits are formed in the cushion layer and the basement bottom plate; a layer of hardpan is paved below the cushion layer; filtering layers are paved around the water-collecting pits; flow-guide pipes are paved in the hardpan and are gathered in the filtering layers; flow-leading pipes are arranged on the side walls of the water-collecting pits; and the water-collecting pits are communicated with the filtering layers through the flow-guide pipes. Water generating floatation outside a basement is led into the basement, so that the floatation is reduced. The hardpan is paved below the cushion layer, so that the problem that water outside foundation pits of the basement is gathered is solved, the underground water is collected through a flow-guide pipe arranged in the hardpan, the flow-leading pipes change the underground water into gravity water in the basement, and the problem of the floatation of the underground water is completely solved from the construction starting stage of a building.

Description

technical field

[0001] The invention relates to a basement structure and a construction method in the construction field, in particular to a pressure relief structure of an anti-floating plate in a basement and a construction method thereof. Background technique

[0002] Over the past 30 years of reform and opening up, with the rapid development of the economy and the acceleration of urban construction, people have higher and higher requirements for the use of basement space. The number of basements and civil air defense basements is increasing, and the area is also increasing. In the design, how to solve the anti-floating problem of the basement has become a frequently faced problem, which has attracted extensive attention of engineers. The anti-floating design of the basement is divided into three situations: 1. After the construction of the basement is completed, the precipitation stops. At this time, even though there are many layers of the above-ground structure, the se...
