Abstract

The invention provides an integrated rapid construction formwork of a drainage ditch and a cable trench of a highway. The integrated rapid construction formwork of the drainage ditch and the cable trench of the highway comprises a cable trench formwork, a drainage ditch formwork and a side form. The cable trench formwork, the drainage ditch formwork and the side form are fixedly connected with a lifting oil cylinder in the manner of capable of horizontally moving through a transverse moving oil cylinder. The lifting oil cylinder is installed on a stand column of a drainage ditch and cable trench trolley in a sleeving manner and can vertically move. The cable trench formwork and the drainage ditch formwork are of a split structure. The overall cable trench is a rectangular box as a whole and composed of a middle box girder, a cable trench left formwork, a cable trench right formwork and a middle box girder connection column. The drainage trench formwork is a rectangular box body as a whole and composed of a diagonal bracing bolt, a first connection rod, a drainage ditch left formwork and a drainage ditch right formwork. The integrated rapid construction formwork of the drainage ditch and the cable trench of the highway can achieve the effects of one-off pouring formation and rapid formwork placement and removal during pouring the drainage ditch and the cable trench of the highway, and the construction quality of the cable trench and the drainage ditch can be guaranteed at the same time.

Description

technical field [0001] The utility model relates to the technical field of tunnel engineering construction, in particular to an overall rapid construction formwork for expressway drains and cable trenches. Background technique [0002] At present, tunnel construction has been implementing standardized construction. Ditch and cable trench trolleys are commonly used as a construction equipment for pouring trench concrete in tunnels. Although they can achieve the purpose of rapid construction, they have difficulties in demoulding, easy damage to edges and corners, and poor appearance quality. Poor, low construction efficiency and other problems. If a formwork for rapid overall construction of drainage ditches and cable trenches can be provided, which has the effects of one-time molding pouring, quick mold placement and demoulding to meet engineering construction, it will significantly reduce material consumption, save labor, and save costs. Contents of the invention [0003]...
