Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction engineering, in particular to a foldable steel arch frame connection component. Background Art

[0002] In the field of tunnel construction and underground engineering, steel arches are an important supporting structure, and their installation speed, quality and stability play a vital role in the safety and efficiency of tunnel construction. Especially under adverse geological conditions, the installation quality of steel arches is directly related to the stability of the tunnel structure and the personal safety of construction workers.

[0003] Traditional steel arch installation methods usually use manual segmented installation, which is not only slow in construction speed and takes up a long time in tunnel construction, but also extremely difficult to install during the installation process, especially in tunnels with smaller cross-sections, due to the limited space inside the tunnel. The operation is cumbersome and the erection quality is difficult to guarantee. In addition, manual high-altitude operations also have great safety hazards. Once an accident occurs, the consequences are disastrous.

[0004] In order to solve the above problems, folding steel arch frame technology has gradually been applied in recent years. The folding steel arch frame is designed with a specific hinge structure so that the steel arch frame can be folded into a smaller volume during transportation and installation, which is convenient for transportation and installation. In addition, when building the steel arch frame, the steel arch frames need to be fixed. The existing fixing method usually uses manual welding of the front and rear spaced steel arch frames at high altitudes, which is not only difficult to operate, but also poses a great safety hazard. Especially when the distance between the steel arch frame and the tunnel surrounding rock is small, manual operation is more difficult and accidents are prone to occur.

[0005] Therefore, it is necessary to develop a new type of foldable steel arch frame connection component, which should be able to solve the problems existing in the prior art, make the steel arch frame more convenient and quick during transportation and installation, and improve construction efficiency and safety.
