Underground anti-floating pool for water drainage and pressure reduction and water drainage and pressure reduction method thereof

Abstract

The invention discloses an underground anti-floating pool for water drainage and pressure reduction. The underground anti-floating pool comprises a pool, a water collecting pit is arranged in the pool and located below a pool reinforced concrete bottom plate, a monitoring well communicated with the water collecting pit is arranged above the water collecting pit, the top elevation of the monitoring well is larger than or equal to the elevation of the pool, and it is guaranteed that the pool and the monitoring well are isolated from each other; a composite inverted filter layer is arranged at the bottom of the pool reinforced concrete bottom plate, a drainage pipe is arranged in the composite inverted filter layer, and the drainage pipe communicates with the water collecting pit; a liquid level regulation and control system is arranged in the monitoring well, and the liquid level in the monitoring well is automatically controlled through the liquid level regulation and control system. According to the underground anti-floating pool for water drainage and pressure reduction and a water drainage and pressure reduction method thereof, the composite inverted filter layer composed of conventional building materials is arranged at the bottom of the pool, underground water is collected and converged into the water collecting pit, the water buoyancy of a bottom plate of the pool is eliminated, and seepage water belongs to clear water, does not take away soil particles of undisturbed soil and does not pollute the environment, so that the underground anti-floating pool for water drainage and pressure reduction and the water drainage and pressure reduction method thereof belongs to an economical and environment-friendly pool anti-floating technology.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an underground anti-floating water pool for releasing water and reducing pressure and an anti-floating method. Background technique [0002] Commonly used anti-float design methods for pools include pressure weight anti-float method, structural anti-float method, and anchoring anti-float method. The anti-float design of the pool is safe by increasing the structural counterweight or increasing the anti-lift bearing capacity. [0003] Pressure weight anti-float method: Anti-floating pressure heavy load includes the self-weight of the bottom plate of the underground structure and its upper part, the self-weight of the structural plate picked out from the bottom plate of the underground structure and the self-weight of the upper covering soil, the self-weight of the upper part of the underground structure or the anti-floating provided by the top pressure structure ca...

AI Technical Summary

Problems solved by technology

[0006] Pressure weight anti-float method, structure anti-float method, anchoring anti-float method all have water buoyancy, and then solve the anti-float of the pool by increasing the structural resistance. It is inevitable to add additional structural pressure or anti-float measures to ensure that the pool safety, there are defects such as long construction period and high investment cost

[0007] Therefore, the anti-floating design method of the pool in the prior art is not perfect, and there are obvious defects
