Construction method of shed tunnel and steel corrugated plate combined type wind-snow prevention system

Abstract

The invention relates to a construction method of a shed tunnel and steel corrugated plate combined type wind-snow prevention system. The construction method comprises the following steps that 1), carrying out construction preparation; 2), supporting and erecting a curved beam side mold and a curved beam bottom mold; 3), hoisting a beam reinforcement cage; 4), carrying out concrete pouring construction on an arc-shaped cross beam; 5), carrying out laying construction on filling wall body; 6), carrying out lintel construction on core columns and window holes; and 7), carrying out installation construction on corrugated plates. The construction method has the beneficial effects that the curved beam side mold and the curved beam bottom mold are convenient in supporting and erecting, mountingand positioning treatment, the template structure integrity is good, the template limiting strength is high, meanwhile, a template supporting system is prone to move on site and high in bearing capacity, and the construction difficulty of template supporting and erecting can be effectively improved; the reinforcement cage is convenient to hoist and connect, the reinforcement cage is prone to locate on site, and the damage of reinforcement cage on site hoisting to the reinforcement cage can be reduced; and arc-shaped cross beam concrete pouring is prone to control, and the concrete compactnessis convenient to control.

Description

technical field [0001] The invention relates to a construction method for a combined wind and snow protection system of shed cave and steel corrugated plate, which can improve the integrity of construction structures, reduce the difficulty of on-site construction positioning, improve on-site construction efficiency, and improve the quality of concrete pouring construction, and belongs to the field of road engineering. Background technique [0002] With the rapid development of highway construction, the highway construction environment is complex and changeable, which brings inconvenience to some highway construction projects in areas with high wind pressure and snow pressure. Considering factors such as site conditions, construction difficulty, personnel safety, and engineering structure reliability, convenience, and construction difficulty, such projects often adopt shed-cave structure schemes to prevent natural disasters. [0003] In the prior art, there is a prefabricated...

AI Technical Summary

Problems solved by technology

The structure has a strong ability to adapt to deformation and is easy to operate and maintain, but the construction volume is large, and it does not involve construction methods such as reducing the difficulty of on-site construction positioning and improving the quality of concrete pouring construction.

[0004] To sum up, the existing construction methods have achieved good results in suitable working conditions, but the construction technology is still not perfect in terms of reducing the difficulty of on-site construction positioning and improving the quality of concrete pouring construction.
