Description

Slurry leakage prevention plugging mechanism and method for concrete construction joint Technical Field The invention relates to the technical field of building construction, in particular to a slurry leakage prevention plugging mechanism and a slurry leakage prevention plugging method for a concrete construction joint. Background The concrete construction joint is a new and old concrete joint surface formed by sectional construction in the concrete pouring process, the structural joint strength is relatively weak, and the concrete construction joint is a key protection part for concrete construction. The protection of the construction joint is divided into two core stages, namely temporary slurry leakage prevention blocking in the concrete pouring process, leakage of the newly poured concrete slurry from a construction joint gap is prevented, corner falling due to concrete edge missing and loose joint surface are avoided, and permanent anti-seepage treatment after the concrete pouring is completed and the strength is achieved, namely, the waterproof performance of the structure is improved by post-pouring processes such as roughening and plastering, embedding a water stop, pouring anti-seepage slurry and the like, wherein the construction stages and the protection purpose are quite different. In the existing construction, aiming at a temporary slurry leakage prevention link in the pouring process, a part of construction side is plugged in a manner of pouring cement slurry and special crack pouring glue, and the method has the obvious defects that firstly, grouting/glue pouring is required to wait for natural airing or solidification to form a sealing effect, slurry is easy to be dispersed by the pressure of newly poured concrete before solidification, an effective slurry leakage prevention effect cannot be achieved, secondly, peripheral impurities in a plugging area are required to be cleaned periodically in the solidification waiting process, foreign matters are prevented from being mixed in to influence the sealing quality, the construction time is greatly occupied, the pouring operation progress is delayed, thirdly, the grouting/glue pouring manner is difficult to adapt to irregular concave-convex surfaces on two sides of a construction joint, empty drums are easy to form at gaps, and the plugging tightness is poor. Some construction side adopts the individual layer template to do temporary shutoff, but traditional template is fixed size, can't adapt to the construction joint of different width in a flexible way, and can only realize unilateral individual layer shutoff, and no multiple seal protection, the leakage slurry risk is still higher, and template and construction joint inner wall laminating degree are poor simultaneously, are difficult to reuse after the dismouting. Disclosure of Invention The invention aims to overcome the defects of the prior art, and provides a slurry leakage prevention plugging mechanism and a slurry leakage prevention plugging method for a concrete construction joint, which solve the problems of low plugging efficiency, poor adaptability and inexact plugging of the existing construction joint, realize double plugging protection of the construction joint, flexibly adapt to the construction joints with different widths, and are convenient and repeatable to assemble and disassemble. In order to achieve the above purpose, the invention adopts the technical scheme that the slurry leakage prevention blocking mechanism for the concrete construction joint comprises: the front plugging plate is used for blocking one side of the construction joint so as to plug the front side of the construction joint; the lateral plugging assembly is arranged at the rear side of the front plugging plate and comprises a first lateral plugging plate and a second lateral plugging plate which are respectively positioned at two sides of the construction joint; The driving assembly is arranged on the front plugging plate, is respectively connected with the first side plugging plate and the second side plugging plate in a transmission way, and is used for driving the first side plugging plate and the second side plugging plate to relatively move so as to compress and plug the inner walls at two sides of the construction joint; the rear plugging structure is arranged at the rear side of the lateral plugging assembly and is connected with the lateral plugging assembly, and is used for synchronously moving in the relative movement process of the first side plugging plate and the second side plugging plate so as to perform rear plugging on the construction joint and form double plugging with the front plugging plate in a matching way.
