Abstract

The invention belongs to the field of structural assembly of soil engineering and relates to a zero-earthing corrugated plate holing structure. The holing structure comprises two bases and an arched corrugated plate structure spanning the two bases; a plane determined by one side, away from the arched corrugated plate structure, of each of the two bases is a first plane; the holing structure further comprises a corrugated plate reinforcing structure arranged on one side, facing the first plane, of the arched corrugated plate structure, an arched reinforcement structure surrounding the exteriorof the arched corrugated plate structure and a lead large pipe shed steel pipe limiting structure, the lead large pipe shed steel pipe limiting structure comprises front end I-steel, tail-end I-steeland one or more lead large pipe shed steel pipe sleeves spanning the front end I-steel and the tail-end I-steel, and the front end I-steel and the tail-end I-steel are arranged on the two sides of the arched corrugated plate structure. With the adoption of the holing structure, safety during tunnel holing is improved, working efficiency and construction accuracy are improved, and a large quantityof manpower and material resources are saved.

Description

technical field [0001] The invention belongs to the field of geotechnical structure assembly, and relates to a zero-covered corrugated board hole structure. Background technique [0002] With the explosive growth of highway mileage, the area of ​​mountainous areas in China is about 2 / 3 of that of plain areas. Therefore, the construction of mountain tunnels has become a controlling project for highway construction. Among the newly built tunnels, there are many tunnels with poor surrounding rock conditions. Whether the tunnel can be successfully drilled in these tunnels has become a key step in tunnel construction. Due to the poor surrounding rock conditions of mountain tunnels and the steep slope at the entrance, incorrect entry methods may cause a large area of ​​talc above the entrance, and in severe cases, the entrance will collapse. Therefore, how to enter the hole easily and safely has always been the focus of research. [0003] There are two types of tunnel entry meth...
