Drainage box culvert pouring supporting structure

Abstract

The invention discloses a drainage box culvert pouring supporting structure. The structure comprises a movable bearing scaffold used for supporting an inner formwork and a top formwork. The structureis suitable for a working area which is narrow in working environment and difficult in mounting and dismounting of an outer mold, and the mounting and dismounting efficiency of the outer mold is improved by adopting a simple truss and a hoisting device; the inner formwork is a detachable combined formwork, and after an adjustable support on the upper portion of a supporting frame is detached, thetop formwork can be integrally pulled down to the supporting frame; an internal movable load-bearing scaffold is integrally reinforced firmly, the scaffold is lifted through a jack, then sliding wheels are additionally arranged, and after the movable load-bearing scaffold is integrally moved to a next working face, the scaffold is fixed after the sliding wheels are detached; the mounting and dismounting frequency of the movable load-bearing scaffold is reduced, and accordingly the mounting and dismounting safety accident rate is reduced; and the single-bin construction period is shortened, theloss of the formworks is reduced, the material turnover rate is increased, the construction cost is reduced, and the construction progress is accelerated.

Description

technical field [0001] The invention relates to the technical field of box culvert construction equipment, in particular to a pouring support structure for a drainage box culvert. Background technique [0002] Box culverts refer to culverts built with reinforced concrete box-shaped pipe joints. Box culverts consist of one or more square or rectangular sections, generally made of reinforced concrete or masonry, but reinforced concrete is widely used. When the span is less than 4m, box culverts are used. For pipe culverts, reinforced concrete box culverts are An inexpensive alternative, the piers, upper and lower slabs are all poured in unison. [0003] When pouring box culverts in some narrow working environments and areas with restricted transportation, the hoisting equipment cannot play a role, and the construction can only be carried out in one direction, and they are all load-bearing structures. And support body installation and disassembly construction efficiency is lo...

Problems solved by technology

[0003] When pouring box culverts in some narrow working environments and areas with restricted transportation, the hoisting equipment cannot play a role, and the construction can only be carried out in one direction, and they are all load-bearing structures. And support body installation and disassembly construction efficiency is low, repeated consumption of manpower and material resources, large amount of material occupation, long construction period
