A drainage system to ensure the stability of groundwater seepage

Abstract

The invention discloses a drainage system for ensuring groundwater seepage stability. The system comprises a floor slab, a drainage pipe, a drainage pipe port, a connector, a waterproof structure, a monitoring system, stirrup reinforcements and the like. The drainage pipe is embedded in the floor slab, the two ends of the drainage pipe penetrate through an underground side wall to communicate withthe side wall of a foundation pit, and water flow on the two sides of the foundation pit runs through. According to an underground water seepage field cut off by foundation construction, the drainagepipeline is arranged along the floor slab, water flowing down from the upstream is led to the downstream, and the downstream water quantity and the flow field are guaranteed to be unchanged. On one hand, the blocking effect of deep foundation pit construction on groundwater seepage is weakened, and the influence of urban building construction on the surrounding environment, especially groundwater, is reduced; on the other hand, the scouring and erosion effects of underground water on a basement due to blockage and siltation after construction is finished are weakened, the water leakage phenomenon of the basement is reduced, the maintenance cost of a building is reduced, the green building development concept of harmonious coexistence of human and nature is met, green economy is realized,and comprehensive popularization can be realized.

Description

technical field [0001] The invention relates to the field of underground drainage, in particular to a drainage system for ensuring the stability of underground water seepage. Background technique [0002] In recent years, the density of urban development has intensified, and the depth of deep foundation pits has increased. In the process of foundation treatment, it is necessary to excavate weak gravel, soil, etc., and then replace them with rubble concrete. Therefore, groundwater seepage channels are blocked, causing Built basement leaks. In addition, because the soil aquifer is cut off, the original groundwater seepage field changes, affecting the regional hydrogeological properties, which may lead to a series of engineering problems. For example: Jinan is located at the northern foot of Mount Tai. The southern part of the urban area belongs to the alluvial and diluvial strata in the piedmont. The bedrock is relatively shallow, and it is generally covered with gravel soil....

[0002] In recent years, the density of urban development has intensified, and the depth of deep foundation pits has increased. In the process of foundation treatment, it is necessary to excavate weak gravel, soil, etc., and then replace them with rubble concrete. Therefore, groundwater seepage channels are blocked, causing Existing basement leaks

In addition, because the soil aquifer is cut off, the original groundwater seepage field changes, affecting the regional hydrogeological properties, which may lead to a series of engineering problems

For example: Jinan is located at the northern foot of Mount Tai. The southern part of the urban area belongs to the alluvial and diluvial strata in the piedmont. The bedrock is relatively shallow, and it is generally covered with gravel soil. Typical hydrogeological characteristics, when developing in this area, it will be faced with intercepting groundwater seepage, changing the seepage field, causing water leakage in the built basement, and adversely affecting the normal flow of spring water in Jinan
