Abstract

The invention discloses a splicing device. The device comprises a first connecting plate and a second connecting plate. The first connecting plate is provided with a first fastening part, the second connecting plate is provided with a second fastening part, the first fastening part and the second fastening part are in one-to-one corresponding and are used for fixing the first connecting plate andthe second connecting plate, one of the first connecting plate and the second connecting plate is provided with a clamping part, the other end is provided with a clamping groove matched with the clamping part in a clamped manner, and the first connecting plate and the second connecting plate are assembled and positioned; and the first fastening part and the second fastening part are kept in aligned state. The splicing device achieves alignment of the first fastening part and the second fastening part, much convenience is brought to a constructor, and construction efficiency is improved. The invention further discloses a steel arch section including the splicing device and a steel arch.

Description

technical field [0001] The invention relates to the technical field of steel arch structures, and more specifically relates to a splicing device. In addition, the present invention also relates to a steel arch section and a steel arch comprising the splicing device. Background technique [0002] With the rapid development of infrastructure construction such as tunnels and underground engineering, the full-face hard rock tunnel boring machine (TBM) has become a complete set of modern tunnel construction equipment. [0003] During TBM tunnel construction, in order to ensure construction quality and safety, steel arches are usually used for support operations. When the surrounding rock of the tunnel is broken or unstable, the steel arch frame is assembled to the excavated tunnel wall to form a support to control the deformation of the surrounding rock and prevent collapse. [0004] The steel arch generally includes multiple arch sections, adjacent arch sections are connected ...
