Underground structure seepage drainage system and construction method thereof

Abstract

The invention discloses an underground structure seepage drainage system and a construction method thereof, and belongs to the technical field of building construction. The underground structure seepage drainage system comprises a seepage drainage ditch, a water collecting well and a baseplate penetrating water release point, wherein the seepage drainage ditch and the water collecting well are communicated through a four-way connector; each of the seepage drainage ditch and the water collecting well consists of a geotextile filter screen, a crushed stone filtering layer and a horizontally arranged water collecting pipe; the baseplate penetrating water release point is arranged at the connecting part of an engineering structure baseplate and the top of the water collecting well; the baseplate penetrating water release point is connected with the water collecting pipe in the water collecting well; openings are formed in the water collecting pipes. Through the arrangement of the seepage drainage system, in the construction period, underground seepage can be drained in time, basement floating caused by underground water buoyancy in the construction period can be effectively avoided, and baseplate structure cracks can be avoided; through underground water decompression, underground water can be reasonably developed and recycled, the purpose of water conservation can be achieved, the influence on geological environment by the seepage drainage system is small, and the construction is not influenced by surrounding environment; the construction process is simple, the operability is strong, and the popularization and application are facilitated.

Description

technical field [0001] The invention belongs to the technical field of building construction, and specifically relates to an underground structure seepage and drainage system arranged under the bottom plate of an engineering structure and a construction method thereof, which can effectively reduce the water buoyancy force on the bottom plate of the structure during the construction stage. Compared with anti-floating anchor rods, The uplift pile has the advantages of saving engineering cost, reducing procedures, reducing costs, speeding up engineering progress, simple process and high controllability. Background technique [0002] Anti-floating anchor rods and anti-lift piles are mostly used in basement engineering structures, and anti-floating measures are mainly used, while dredging and drainage measures are relatively seldom used, which is not conducive to cost saving; during the construction stage, precipitation is required to avoid water buoyancy from cracking the structu...
