Pipe gallery guide wall external formwork and building method thereof

Abstract

The invention relates to a pipe gallery guide wall external formwork, and belongs to the field of pipe gallery construction. The pipe gallery guide wall external formwork is convenient to mount and dismount, the labor cost is lowered, the turnover efficiency is improved, the construction period is shortened, the construction quality is ensured, and a building method of the pipe gallery guide wallexternal formwork is short in formwork filling time. The pipe gallery guide wall external formwork comprises a plurality of steel external formwork units distributed longitudinally and connection parts enabling two adjacent external formwork units to be in butting joint with each other, wherein the connection parts are detachably connected with the external formwork units. A supporting system forsupporting the corresponding external formwork unit is arranged on the outer side of each external formwork unit. A walking system is arranged at the bottom of the outer side of each external formworkunit. According to the pipe gallery external formwork, dismounting and mounting of the pipe gallery guide wall external formwork are facilitated; the phenomena of grout leakage, formwork swelling, water leakage and water seepage are relieved; and the turnover efficiency of the formwork is improved. According to the building method of the pipe gallery guide wall external formwork, the number of construction personnel is reduced, the transferring rate of the external formwork units is improved, and the formwork filling time is shortened.

Description

technical field [0001] The invention belongs to the field of pipe gallery construction, in particular to an outer formwork for a guide wall of a pipe gallery and a method for erecting the same. Background technique [0002] At present, two pourings are usually used in the construction of the pipe gallery, that is, from the bottom to the top, the lower part of the guide wall is poured first, and then the remaining part is poured. When the guide wall is poured, the outer formwork is mostly made of wood formwork, aluminum formwork and wood-plastic formwork. Among them, the wooden formwork requires more supporting components; it takes a long time to set up and remove the formwork, and the turnover efficiency is low; the erection, transfer and disassembly of the formwork all require more labor costs; Phenomena such as slurry leakage and mold expansion are prone to occur, resulting in poor molding effect after mold removal, and common quality problems such as wrong platform, hone...

AI Technical Summary

Problems solved by technology

Among them, the wooden formwork requires more supporting components; it takes a long time to set up and remove the formwork, and the turnover efficiency is low; the erection, transfer and disassembly of the formwork all require more labor costs; Phenomena such as slurry leakage and mold expansion are prone to occur, resulting in poor molding effect after mold removal, and common quality problems such as wrong platform, honeycomb, and pockmarked surface are prone to occur

Aluminum formwork also requires more labor; the turnover speed is slightly faster than wooden formwork, but the overall efficiency is not high; because aluminum formwork is divided into small blocks, there are many splicing, grout leakage is prone to occur during pouring, and the joints after formwork removal It is easy to have a wrong platform, and the molding effect is average

Wood-plastic molds also require more labor costs and supporting components; the turnover efficiency is low; and their rigidity is poor, and mold expansion is prone to occur during pouring, and the molding effect is average
