Abstract

The invention discloses an anti-floating inverted arch formwork system. The anti-floating inverted arch formwork system comprises an inverted arch formwork and further comprises a supporting frameworklocated above the inverted arch formwork, a plurality of connecting parts are arranged between the supporting framework and the inverted arch formwork, and the multiple connecting parts are arrangedat intervals in the width direction and the length direction of the inverted arch formwork; and the supporting framework is provided with a plurality of lifting components arranged in the vertical direction, and the lifting components are provided with pressure detection components in a matched mode. The anti-floating inverted arch formwork system has the advantages of being simple and reliable instructure, beneficial to reducing labor intensity, good in anti-floating effect, capable of being repeatedly used and the like.

Description

technical field [0001] The invention relates to equipment for tunnel construction, in particular to an anti-floating inverted arch formwork system. Background technique [0002] In tunnel construction, the level of mechanized construction is getting higher and higher, and the process organization in each area is also relatively professional. In the inverted arch filled concrete construction area, the promotion and use of self-propelled inverted arch trestle makes the construction in this area safer and more efficient. The popularization and use of the integral inverted arch formwork has realized the rapid construction of the inverted arch, saved the assembly and dismantling of the formwork, greatly reduced the labor intensity of the workers, and improved the efficiency and quality of the inverted arch construction. The combination of self-propelled inverted arch trestle and integral inverted arch formwork meets the mechanization, automation, generalization and standardizati...
