Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects of the prior art, to provide a plugging method between the surrounding protection piles of the foundation pit, which solves the problem of difficult plugging of the seepage between the surrounding protection piles, and through sealing two adjacent surrounding protection piles The gap between the piles is used to prevent groundwater from flowing into the foundation pit from the gap between the retaining piles, which ensures the construction quality and eliminates potential safety hazards

specific Embodiment approach

[0081] When the surrounding protection pile 21 is a bored cast-in-place pile, the fixing part 11 is fixed to the surrounding protection pile 21 by bolts 15. The fixing part 11 can be a steel plate or a U-shaped structure in cross section, which can be determined according to the leakage situation and the actual situation. The construction conditions are selected, along the excavation depth of the foundation pit 22, the fixing parts 11 are installed and grouted until the foundation pit 22 is excavated, at this time, a number of end-to-end fixing parts 11 are installed along the height direction of the enclosure pile 21, To form an integrated structure, so as to seal the gap between the two retaining piles 21 and prevent the leakage of accumulated water;

[0082] When the surrounding protection pile 21 is a SMW construction method pile, use the magnet 16 to fix the fixing part on the surrounding protection pile 21. The fixing part 11 can be a steel plate or a U-shaped structure i...

Abstract

The invention relates to a method for leaking stoppage between foundation pit enclosing piles. The method comprises the following steps that a fixing piece is provided, the fixing piece is placed on the bottom surface of an excavated part of a foundation pit, the fixing piece is fixedly connected with the fender posts on the two sides of a leaking part, so that the fixing piece shields the leaking part, and a pouring space is formed by enclosing the fixing piece and a soil body between the two fender posts; and grouting is carried out in the pouring space to block the gap between every two adjacent fender posts, and therefore accumulated water is prevented from leaking into the foundation pit from the leaking part. The problem that the leaking part between the fender posts is difficult to block is effectively solved, the gap between every two adjacent fender posts is blocked, underground water is prevented from flowing into the foundation pit from the gap between the fender posts, the construction quality is guaranteed, and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for plugging leakage between protection piles surrounding a foundation pit. Background technique [0002] The construction speed of the foundation pit project directly determines the construction period of the entire project, and the construction quality of the foundation pit enclosure determines the construction speed of the foundation pit project, especially in the stratum with a relatively high groundwater level. If the construction of the foundation pit enclosure Poor quality will cause water outside the foundation pit enclosure to leak into the foundation pit, which will not only affect the construction period, but also cause safety accidents. [0003] Bored cast-in-situ piles are widely used in foundation pit protection, especially in deep foundation pit projects, because of their mature technology, convenient construction, and good mechanical performance. Wat...
