Description

Quick connecting device of assembled bellows open cut tunnel

Technical Field

The utility model relates to the technical field of engineering construction, in particular to a rapid connecting device for an open cut tunnel of an assembled corrugated pipe.

Background

The corrugated steel member is formed by continuously splicing cold-rolled corrugated steel, and is a novel efficient section. The corrugated steel plate has unique stress characteristics, has extremely small compressive rigidity along the corrugated direction, and has much higher bending rigidity perpendicular to the corrugated direction than the flat steel plate with the same thickness. Therefore, the corrugated plate hardly bears normal stress along the longitudinal direction of the member, does not bulge under axial load, and the integral shear buckling load is greatly improved.

The corrugated steel structure has a very wide application field, such as corrugated pipes, which are one form of corrugated pipes or corrugated arc plates formed by connecting and assembling. The steel corrugated pipe has excellent stress characteristics due to the axial corrugation, and stress strain caused by load is distributed in the axial direction and the radial direction at the same time, so that the stress concentration of the load can be dispersed to a greater extent, and the advantages of the steel structure can be better exerted. Especially in bad engineering rock-soil areas such as soft soil, expansive soil, collapsible loess and the like, the steel corrugated pipe is utilized to build the culvert with advantages.

Although the advantage of corrugated steel structure is obvious in comparison with traditional concrete structure, but the junction of corrugated steel is the weak link of structure, and the atress form is complicated, and current connected mode can not be suitable for the atress condition of corrugated steel completely, has restrained the popularization and application of corrugated steel yet, influences structural durability. Unlike conventional steel structures, the curvature of the corrugated steel structure in the longitudinal and transverse directions makes the local structure stressed very complex when the corrugated steel structure is subjected to external load, and the damage of the connecting part can be caused by the subtle changes of the external environment and the initial state. It has been investigated that in existing corrugated steel product applications, joint failure has been a primary problem.

Therefore, a quick connection device for an open cut tunnel of an assembled corrugated pipe is needed to solve the above-described technical problems.
