Abstract

The invention provides a method for constructing a special-shaped template of a comprehensive pipe gallery. The method comprises the following steps that 1, according to the construction drawing, modeling design on the special-shaped template is carried out, the size of a standard section is determined and a manufacturing material is selected; 2, the size of a fixed template is determined and thenbent according to the angle requirement of a special-shaped part of the comprehensive pipe gallery, then a spliced template is processed according to the size of the fixed template, and finally the spliced template is spliced and fixed to the fixed template to form the special-shaped template; 3, the special-shaped template is integrally arranged at the special-shaped part of the comprehensive pipe gallery, and a supporting frame is built in the fixed template for reinforcing the special-shaped template; and 4, after the special-shaped template is fixed, concrete pouring is carried out on thespecial-shaped part of the comprehensive pipe gallery, the special-shaped template is disassembled after pouring is completed, and the special-shaped template is pushed and conveyed to the next construction section for further construction. According to the method for constructing the special-shaped template of the comprehensive pipe gallery, the difficulty of installation of the special-shaped template in the construction process is lowered, and the time required for the installation of the special-shaped template in the construction process is shortened.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a construction method of a special-shaped formwork for a comprehensive pipe gallery. Background technique [0002] At present, most of the underground comprehensive pipe galleries in China are constructed using the cast-in-place process. When constructing the side walls of large-scale comprehensive pipe galleries (multi-warehouse structures), it will be found that the partition walls between the warehouses and the inner sides of the top corners of the outer walls are different. The regular and irregular structure leads to a large amount of formwork matching and loss of formwork during the installation of the formwork at this part. At the same time, because the structure of the comprehensive pipe gallery itself is narrow in width and high in height, it is very inconvenient to install the formwork at this place, and even if the installation is completed, there will be a lo...
