Advanced water prevention construction process for post-cast strip of side wall of basement

Abstract

The invention discloses an advanced water prevention construction process for a post-cast strip of the side wall of a basement. The advanced water prevention construction process comprises the steps of detaching a formwork, cleaning the post-cast strip, prefabricating a reinforced concrete baffle, mounting the baffle, smearing the outer side of the baffle with lime, and conducting construction on a waterproof roll and a protection wall, wherein construction on the waterproof roll and the protection wall can be conducted seven days after the outer side of the baffle is smeared with the lime. The construction process is short in construction period, the later construction is not affected, the post-cast strip can be protected, and a retaining wall is high in strength, good in stability and can bear impact force generated during earthwork backfilling; construction difficulty is low; and the problems that an existing construction process is long in construction period, influence on the later construction is large, protection of the post-cast strip is not easy, and a retaining wall is low in strength, poor in stability and extremely prone to collapsing under earthwork impact in the earthwork backfilling process are solved.

Description

technical field [0001] The invention relates to a construction technology, in particular to an advanced waterproof construction technology of a basement side wall after pouring. Background technique [0002] The post-pouring belt is a temporary part set at the corresponding positions of the foundation floor, wall and beam in order to prevent the harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven shrinkage or uneven settlement during construction. construction joints. The post-pouring belt is an effective measure that can not only solve the settlement difference but also reduce the shrinkage stress, so it is widely used in engineering. The post-pouring belt temporarily divides the structure into several parts, and after a certain period of time, the construction joint concrete is poured and tamped after the internal contraction of the components to connect the structure into a whole. The pouring time of the post-casting belt shoul...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is that the existing construction technology has a long construction period, which has a great influence on the subsequent construction, and it is not easy to protect the post-casting belt. The strength of the retaining wall is not high, and the stability is poor. It is very easy to collapse, and the purpose is to provide an advanced waterproof construction technology for the post-cast belt on the side wall of the basement, which solves the long construction period of the existing construction technology, which has a great impact on subsequent construction, is difficult to protect the post-cast belt, and the strength of the retaining wall is not high , the stability is poor, and when the earthwork is backfilled, it is easy to collapse under the impact of the earthwork
