A full hydraulic formwork system for culvert pouring

Abstract

The invention relates to the culvert construction technical field, and specifically relates to an all hydraulic template system for culvert pouring; the system comprises a top template and a bottom template capable of sliding on vertical slide rails on two sides of the culvert; the bottom template is provided with a bottom template inner framework and a bottom template outer framework used for pouring a bottom board and a first side wall, wherein the bottom template inner and outer frameworks are supported and pushed by a double-head oil cylinder; the top template is provided with a top template inner framework and a top template outer framework used for pouring a top board and a second side wall, wherein the top template inner and outer frameworks are supported and pushed by a double-head oil cylinder; the top template and bottom template are alternatively carried out so as to pour the culvert by layers. The modularized splicing structure is employed, and the system can be assembled according to the sizes of a frame box culvert, thus solving the problems that frame box culverts are various in sizes, improving working efficiency, and reducing cost.

Description

technical field [0001] The invention relates to the technical field of culvert construction, in particular to a fully hydraulic formwork system for culvert pouring. Background technique [0002] The difficulty of culverts is that there are many construction procedures, layered and sectioned pouring, complex formwork reinforcement, different culvert sizes, slow construction progress, and large formwork loss. There are generally two ways of culvert formwork currently used. One is the wooden formwork made of bamboo plywood. The formwork is temporarily processed through the culvert structure size and installed manually on site. It is simple, easy to install and operate, and the formwork is easy to remove. The disadvantage is that it is not suitable for large-volume concrete pouring, the bearing capacity and rigidity are small, and the reuse efficiency of the formwork is low; Reinforced by means of braces, the advantage is that the bearing capacity and rigidity can meet the need...
