Leaking stoppage grouting device between deep foundation pit fender posts

Abstract

The invention relates to the technical field of civil construction, in particular to a leaking stoppage grouting device between deep foundation pit fender posts. The leaking stoppage grouting device between the deep foundation pit fender posts comprises a grouting chamber plate, two fixing plates and a span adjusting assembly, wherein the two fixing plates are slidably assembled on the left side and the right side of the grouting chamber plate in a mirror symmetry mode, and the span adjusting assembly is installed on the outer plate face of the grouting chamber plate and arranged between the two fixing plates. According to the leaking stoppage grouting device between the deep foundation pit fender posts, a traditional leaking stoppage grouting device of a fixing plate-shaped structure is improved, and the problems that installation is inconvenient due to the fact that the installation size is not matched, and installation and disassembly are troublesome due to the fact that holes need to be correspondingly drilled step by step for device fixing during deep foundation pit fender post leaking stoppage construction operation are solved.

Description

technical field [0001] The invention relates to the technical field of civil building construction, and specifically provides a plugging and grouting device for deep foundation pit enclosure piles. Background technique [0002] Deep foundation pit construction is a very common construction method in the process of modern civil engineering construction. Deep foundation pits are generally excavated as shallow as a few meters deep, and as deep as tens of meters deep. Deep foundation pit construction can be used for underground space. For example, in the construction of urban roads, in order to achieve high-standard planning and design, the construction of underground pipe corridors is an indispensable construction process, that is, to build a tunnel space underground in urban roads, and integrate electricity, communications, gas, heating, water supply and drainage Various engineering pipelines are integrated and arranged in the tunnel space, and special inspection ports, hoisti...

Problems solved by technology

[0005]1) Interval-type bored piles adopt interval-type drilling, because the size of the bored piles and the distance between adjacent cast-in-place piles are not strictly in accordance with a certain size Therefore, there is a certain size mismatch problem between the plugging and grouting device for fixing the traditional plate structure and the retaining pile;

[0006]2) During the excavation of deep foundation pits, the traditional plugging and grouting devices also adopt a step-by-step docking structure design for deep plugging of foundation pits. However, after the docking, it is necessary to drill and lock the two retaining piles at the corresponding positions of each plugging and grouting device. Not only is it troublesome to drill holes before fixing, but it is also troublesome to disassemble after the grouting is completed.
