Abstract

The invention belongs to the technical field of positioning construction during welding of a steel arch connecting steel plate in preliminary bracing of a tunnel, and discloses a positioning clamper suitable for a steel arch connecting plate and a construction method. The positioning clamper comprises a clamping plate, a limiting plate and a bottom support; the clamping plate and a connecting cushion plate correspond in size; a clamping groove with an U-shaped structure is formed in the clamping plate; the clamping groove corresponds to an arch of a steel arch; one end surface of the limitingplate is fixed at the middle part of the outer side of a middle plate of the clamping plate; the front and back sides of the limiting plate are projected on the clamping plate for limiting the connecting cushion plate; the bottom support is fixed on the outer wall of one side wall of the clamping plate; and the limiting plate and the bottom support commonly limit the connecting cushion plate. Thepositioning clamper improves the working efficiency, greatly shortens the positioning correction time and the scene assembly time of the connecting cushion plate before welding when the connecting quality is guaranteed, saves the labor cost, and accelerates the construction progress.

Description

technical field [0001] The invention belongs to the technical field of positioning construction during the welding of steel arch connection plates in the primary support of tunnels, and relates to a positioning fixture and a construction method suitable for steel arch connection plates. Background technique [0002] With the construction of national high-speed and railway networks, tunnel projects are increasing day by day. The new Austrian method is mostly used in the tunnel construction. How to ensure the safety of the tunnel construction and improve the quality of the tunnel construction is one of the important issues for the construction personnel. The initial support of the tunnel is an important part of the construction of the new Austrian method, and the steel arch in the initial support is an important structure to restrain the deformation of the surrounding rock. Due to construction needs, steel arches are processed in sections at the steel bar processing site, and...
