Integral hydraulic formwork applied to box culvert prefabrication

Abstract

The invention belongs to the field of box culvert pouring, and provides an integral hydraulic formwork applied to box culvert prefabrication. The integral hydraulic formwork comprises an internal formwork component, a bottom formwork component, an external formwork component, an end formwork component and a retaining formwork component; the internal formwork component includes internal formworks and an internal top formwork; the internal formworks include the first internal formwork and the second internal formwork; the bottom formwork component includes a bottom formwork; the external formwork component includes external formworks; the external formworks include the first external formwork and the second external formwork; the retaining formwork component includes a first retaining formwork and a second retaining formwork; the end formwork component includes a convex end formwork and a concave end formwork; and the space enclosed by the first external formwork, the second external formwork, the first internal formwork, the second internal formwork, the internal top formwork, the bottom formwork, the first retaining formwork, the second retaining formwork, the convex end formwork and the concave end formwork is used for pouring concrete. By mean of the integral hydraulic formwork applied to box culvert prefabrication, the prefabrication quality is high and stable, the adopted set shaped steel formwork has high surface rigidity, is not prone to deforming, and has good flatness.

Description

technical field

[0001] The invention relates to the technical field of pouring of assembled prefabricated box culverts, in particular to an integral hydraulic formwork applied to box culvert prefabrication. Background technique

[0002] The box culvert is a kind of culvert in bridge and culvert engineering. The prefabricated box culvert is poured and formed on an independent site, and then transported to the culvert construction site for assembly, which can speed up the progress of the project and save the construction period; The formwork needs to be assembled, and after the concrete is poured, the formwork needs to be disassembled. Since the formwork is composed of many small formworks, the operation of disassembling and assembling the formwork in the prefabricated box culvert construction is cumbersome and the work efficiency is low. The number of installations is more and the work efficiency is lower. Therefore, the existing prefabricated formwork for box culverts is not...
