Fixed device for curb side ditch formworks in tunnel

Abstract

The invention provides a fixed device for curb side ditch formworks in a tunnel. The fixed device comprises two fixed device bodies, wherein the two fixed device bodies are respectively arranged on both ends of the curb side ditch formworks; the two fixed device bodies are connected through a connecting assembly; the fixed device bodies comprise truss structures; and the curb side ditch formworks include side ditch side formworks and side ditch top formworks, the side ditch top formworks are installed on the tops of the truss structures, and the side ditch side formworks are installed on the side walls of the truss structures. According to the structure, the curb side ditch formworks and road surface formworks do not interfere with each other, so that the purpose of integral pouring is achieved, and the problem of potential quality hazards caused by two skins of curb side ditches and tunnel road surface slabs because a traditional construction method provided in the background technology cannot achieve the purpose of integral pouring of the curb side ditches and the road surface slabs is solved.

Description

technical field [0001] The invention belongs to the field of road construction, and in particular relates to a fixing device for a curb and side ditch formwork in a tunnel. Background technique [0002] In the construction of curb ditches in expressway tunnels, the traditional process is to install formwork for curb ditch construction after the construction of the road slab in the tunnel is completed, but the traditional construction method cannot achieve the purpose of integral pouring of the curb ditch and road slab. Moreover, due to the small pouring area, it is difficult to vibrate and compact the concrete. In addition, the thickness of the curb gutter is small, which may easily cause two skins between the curb gutter and the tunnel road slab, causing quality problems. Contents of the invention [0003] The object of the present invention is to provide a fixing device for the curb gutter template in the tunnel, which solves the above-mentioned shortcomings in the prior...
