Basement anti-floating dewatering and drainage system and construction method thereof

Abstract

The invention discloses a basement anti-floating dewatering and drainage system and a construction method thereof. The basement anti-floating dewatering and drainage system comprises a water filter layer (1), a middle partition layer (2), a soil layer (3) and a dewatering well (4); the periphery of a basement bottom plate (5) is backfilled with the water filter layer (1), the middle partition layer (2) is arranged at the top of the water filter layer (1), the top of the middle partition layer (2) is backfilled with the soil layer (3) along a foundation pit side wall (6), and the soil layer (3)communicates with the water filter layer (1) through the middle partition layer (2); and the dewatering well (4) is arranged on the outer side of a basement, the bottom of the dewatering well (4) extends into the water filter layer (1) and communicates with the water filter layer (1), the top of the dewatering well (4) penetrates through the soil layer (3), the top face of the dewatering well (4)and the top face of the soil layer (3) are both elevated to the ground, and a water pump chain block (41) is arranged in the dewatering well (4). The anti-floating and dewatering and drainage problems can be solved through the dewatering and drainage system constructed synchronously with the basement, and the purposes of dewatering and drainage are achieved by combining a blind ditch with a drainage well.

Description

technical field [0001] The invention relates to a building drainage system and a construction method thereof, in particular to a basement anti-floating drainage system and a construction method thereof. Background technique [0002] With the rapid development of cities, the problem of scarcity of land resources is becoming more and more serious. The development and utilization of underground space has become the focus of attention in the field of construction. Basements can be used as garages, storage rooms, shopping malls and even residences, which greatly solves the problem of urban Spatial issues in architectural design. [0003] Because the eastern and southern regions of China are near the sea, where the groundwater pressure is high, and the basement is soaked in seawater for a long time, the waterproof and moisture-proof problem of the basement is an important part in the design of the underground space. In order to solve the waterproof problem of the basement, at the...

AI Technical Summary

Problems solved by technology

[0004] At present, the basement is drained through blind ditch and blind ditch pipes during construction. The layout of blind ditch pipes is complicated, the construction requirements and costs are high, and the site is restricted, and the drainage effect is poor, especially in coastal areas. , unable to meet architectural design requirements such as anti-floating, lowering and drainage, etc., there are great safety hazards
