Problems solved by technology

[0003] However, the traditional pre-embedded double-fluid grouting plugging structure obviously has the following problems in actual use. The grout in the early stage of grouting is easily washed away, so the expected effect can only be achieved after a period of grouting, and there is a plugging speed slow and inefficient

Abstract

The invention discloses a foundation pit pre-buried type double-liquid grouting plugging structure, which comprises a circular fixing cylinder, two grouting through holes are opened on the circular fixing cylinder, and the inner walls of the two grouting through holes are There are a plurality of limit chutes on each of the limit chutes, and a limit slider is slidably installed on each limit chute, and a plurality of limit sliders located in the same grouting through hole are fixed and installed together. A ring seat 1, a rotating rod is installed in the ring seat 1 through a rotating connection structure; a fixed ring is fixedly installed on the lower ends of the two ring seat 1, and a fixed ring is fixedly installed on the lower ends of the two said fixed rings. A plugging seat 1, two stepped grooves 2 are symmetrically opened on the plugging seat 1. The advantage is that the setting of the plugging seat 1 is convenient to directly block the water at the leaking place, so that the grout injected through the grouting through hole can be better shaped at the leaking place, and the injected grout can be avoided from excessive water velocity. Disperse.

Description

technical field [0001] The invention relates to a double-liquid grouting plugging structure, in particular to a foundation pit pre-embedded double-liquid grouting plugging structure. Background technique [0002] During the excavation of the foundation pit, the circulation of the inner and outer water layers of the foundation pit will be avoided by the setting of the concrete water-stop wall. When the error is large, it is easy to break the water layer, resulting in water leakage. In this case, the pre-embedded double-liquid grouting plugging structure will be used to plug the leakage; [0003] However, the traditional pre-embedded dual-liquid grouting plugging structure has the following problems when it is used in practice. The slurry in the early stage of grouting is easy to be washed away, so the expected effect can only be achieved after grouting for a period of time. slow and inefficient. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to ...
