Abstract

The invention discloses an underground pipe gallery cast-in-situ aluminum film construction method. The underground pipe gallery cast-in-situ aluminum film construction method comprises the steps thatpaying off before construction is carried out; wall aluminum templates are installed after paying off; mold removal is carried out after wall pouring; and as for installation of the wall aluminum templates, firstly, after a bottom plate and guide wall steel bars are installed, internal braces are arranged at the positions of the horizontal distances and the vertical distances between the steel bars and all wall-through screws, the internal braces are the same as a wall in width, the upper and lower surfaces of the inner braces are horizontal, and the left and right directions of the internalbraces and the wall line form right angles. By means of the underground pipe gallery cast-in-situ aluminum film construction method, through the arrangement of a series of structures, the constructionquality of a pipe gallery can be ensured in the implementation process, and meanwhile, a user can conveniently uses a mold.

Description

technical field [0001] The invention relates to the field of pipe gallery construction, in particular to a construction method of cast-in-place aluminum film for an underground pipe gallery. Background technique [0002] The urban underground comprehensive pipe gallery can integrate power, communication, gas, heating, water supply and drainage and other engineering pipelines into one, and uniformly distribute and arrange them. Considering that the design service life of the underground pipe gallery is usually 100 years, the construction should ensure that the pipe gallery has sufficient durability, applicability and safety. [0003] During the construction of the traditional pipe gallery, formwork is required to facilitate the pouring and improve the quality of the pipe gallery. However, when the traditional formwork is used, it has the disadvantages of heavy weight and easy deformation. Moreover, when the formwork is constructed and removed, the construction strength is re...
