Embodiment 1

[0022] Embodiment 1: referring to Fig. 1, the processing method of seepage water at the bottom of deep foundation pit pit, it comprises the steps:

[0023] 1) Firstly, dig a drainage blind ditch 2 at the bottom of the deep foundation pit 1 where water leakage has occurred or next to it, and a blind well 3 is dug at the end of the drainage blind ditch 2, and the blind well 3 is connected to the drainage blind ditch 2;

[0024] 2) Backfill the filter material 4 in the drainage blind ditch 2 (the filter material is graded sand and gravel, etc.); set a plurality of drainage pipes 5 in the blind well 3 (the drainage pipes are set away from the cap), and the lower ends of the drainage pipes 5 The side of the part is opened, and the water pump 6 is installed in the drain pipe 5 (in order to extract the water from the drainage blind ditch 2 to the blind well 3, and the water outlet pipe 9 of the water pump leads to the outside of the drain pipe 5); the drain pipe 5 is a metal pipe, gl...

Abstract

The invention relates to a method for processing the water leakage of a soil layer which is arranged on the bottom portion of a deep foundation pit. The method for processing the water leakage of a soil layer which is arranged on the bottom portion of a deep foundation pit is characterized in that the method comprises the following steps: V1ing, firstly, a position and the side in the bottom portion of the deep foundation pit, where leakages water are dug with a blind drainage ditch, a blind shaft is dug on the end portion of the blind drainage ditch, the blind shaft and the blind drainage ditch are communicated, and the blind drainage ditch and the blind shaft are arranged under the bottom portion of the deep foundation pit. V2ing, filter materials are backfilled in the blind drainage ditch, a drainage pipe is arranged in the blind shaft, an opening is opened on the side surface of the lower end portion of the drainage pipe, a water pump is arranged in the drainage pipe, at the same time or after the drainage pipe is arranged, the filter materials are backfilled in the blind shaft. V3ing, concrete slabs are cast on the upper portions of the blind drainage ditch and the blind shaft and the lower portion of a basement foundation slab or a foundation base. V4ing, the water pump is opened to discharge. The construction method of the invention is simple, the effect is excellent, the water leakage of the soil layer which is arranged on the bottom portion of a deep foundation pit is capable of being effectively treated.

Description

technical field [0001] The invention belongs to the fields of civil engineering construction and municipal construction, and in particular relates to a method for treating seepage water in a soil layer at the bottom of a deep foundation pit. Background technique [0002] In the field of civil engineering and municipal construction, due to the large difference in the groundwater head inside and outside the pit after the excavation of the deep foundation pit, the complexity of the soil layer, and the construction of engineering piles, etc., it is easy to cause the concrete in the basement floor after the deep foundation pit is excavated to the bottom. Before pouring, there was a problem of water leakage at the bottom of the deep foundation pit, which made it impossible to continue construction in the basement, affected the construction period, increased costs, and brought safety hazards or even safety accidents to the surrounding environment and deep foundation pits. [0003] ...
