Construction method of reinforced raft post-cast strip slurry blocking strips

Abstract

The invention discloses a construction method of reinforced raft post-cast strip slurry blocking strips. The method is characterized in that after a post-cast strip concrete cushion layer is subjectedto pouring, a waterproof layer is constructed, a concrete reinforcing layer is arranged at the upper portion of the waterproof layer, a form is erected on the waterproof layer, first battens are fixed on the positions, on the two sides of the post-cast strip, of the cushion layer, second battens are transversely placed in the post-cast strip, two third battens in the post-cast strip are firmly fixed on the lower portion through a gluing form, fourth battens are arranged on the upper portions of all the battens to fix all the battens into a whole, the concrete reinforcing layer at the bottom of the post-cast strip is subjected to pouring to achieve the bottom face of the gluing form, the edges of the two sides of the post-cast strip is subjected to pouring to be higher then the waterprooflayer to form slurry blocking strips, other positions are subjected to pouring to be flush with the positions, on the edges of the two sides of the post-cast strip, of the waterproof layer, form stripping is conducted after concrete reaches the strength, and construction of the post-cast strip slurry blocking strips is completed. According to the method, the bottom slurry leakage during concrete pouring on the two sides of the post-cast strip is effectively prevented, and the slurry blocking strips and the post-cast strip are subjected to pouring together into a whole, so that the thickness ofa post-cast strip steel bar protection layer is ensured, and the construction quality is improved.

Description

technical field [0001] The invention relates to the technical field of civil construction engineering, in particular to a construction method of a reinforced raft slab post-pouring with grout bars. Background technique [0002] During the construction of the traditional raft slab post-pouring belt, the gap between the lower steel bars and the base layer on both sides of the post-pouring belt is generally sealed with mortar or not treated at all. The gap cannot be fully vibrated, which will affect the compactness of concrete pouring. The loss of concrete slurry in the raft slab seriously affects the quality of concrete pouring, and the concrete slurry flows into the post-casting zone, which makes cleaning difficult. If the concrete in the post-casting zone is not cleaned in time before the initial setting of the concrete, it will take a lot of manpower and material resources to clean up later. It is difficult to meet the sealing requirements if the post-casting belt is not c...

The loss of concrete slurry in the raft slab seriously affects the quality of concrete pouring, and the concrete slurry flows into the post-casting zone, which makes cleaning difficult. If the concrete in the post-casting zone is not cleaned in time before the initial setting of the concrete, it will take a lot of manpower and material resources to clean it later. Pouring belt, and the post-casting belt is not cleaned up, it is difficult to meet the sealing requirements
