Construction method for preventing leakage of large-area basement

Abstract

The invention discloses a construction method for preventing leakage of a large-area basement. The construction method comprises the following steps of 1, mounting a template, specifically, selecting a pouring template made of 60 * 80 square timber, during outer wall construction, splicing a large template on the outer side of an outer wall, fixing the large template longitudinally and transversely in two directions by using steel pipes, and adhering the contact parts of a construction structure by using double-sided foam glue for fixing, meanwhile, adopting a connecting iron hoop for fixing at a mold hanging position. The construction method has the beneficial effects that by strictly controlling the construction process of the template, a steel bar connecting and fixing position and a construction joint pouring position used in the basement construction process, generation of a basement leakage structure is effectively reduced from the source, and the leakage-proof construction quality of the basement is greatly improved; according to the construction method, the basement leakage structure is flexibly inspected and repaired after construction, the safety of the basement in use is further ensured, and the construction method is convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of basement anti-leakage construction, in particular to a large-area basement anti-leakage construction method. Background technique [0002] With the gradual increase in the number of large-scale projects, large-area concrete structures in the field of underground engineering continue to increase. In order to ensure the long-term and safe use of underground projects, it is often necessary to take anti-leakage measures during the construction of underground projects, among which the basement is anti-leakage received widespread attention. [0003] At present, the main reason for the leakage during the construction process of the existing large-area basement is that the joint structure of the formwork and the unreasonable fixation of the steel bar binding position are also the main reasons for the leakage. , In addition, most of the existing basements are directly put into use after construction, resulting in...

[0003] At present, the main reason for the leakage during the construction process of the existing large-area basement is that the joint structure of the formwork and the unreasonable fixation of the steel bar binding position are also the main reasons for the leakage. In addition, most of the existing basements are directly put into use after construction, resulting in some leaks not being repaired in time, which reduces the safety of the basement when it is put into use
