Embodiment Construction

[0043] The technical solutions in this application will be further described in detail below in conjunction with the accompanying drawings.

[0044] The embodiment of the present application discloses a tunnel steel frame support structure. Please refer to figure 1 and figure 2 A tunnel steel frame support structure includes a positioning seat 1, a steel mesh 2 and a steel beam 3. A positioning plate 11 is fixedly arranged on the positioning seat 1 , and the surface where the positioning plate 11 is located is perpendicular to the surface where the positioning seat 1 is located. A through hole for the grouting anchor to pass is opened on the positioning seat 1 . After the grouting anchor is fixed on the tunnel, pass the exposed part of the grouting anchor through the via hole, install a nut on the grouting anchor, and use the nut to press the positioning seat 1 on the tunnel. The positioning seat 1 is elongated along the excavation direction of the tunnel, and is evenly a...

Abstract

The present application relates to the technical field of tunnel construction, in particular to a tunnel steel frame support structure and a construction method, including a positioning seat, a steel mesh and a steel beam, a positioning plate is fixedly arranged on the positioning seat, and a There are holes for anchor rods to pass through; the positioning plate is provided with a first accommodation groove for placing steel mesh, and the positioning plate on one side of the first accommodation groove is hinged with a limit column, and the limit column A limit block is slid on the position post, and a limit slot matching the positioning plate is provided on the limit block, and an elastic member for pushing the limit block to move away from the hinge shaft is arranged on the limit post. When the limiting column rotates to be coplanar with the positioning plate, the limiting block protrudes and snaps together with the positioning plate; the positioning plate is provided with a second accommodating groove for placing a steel beam, adjacent to the steel beam Beam bolted connections. Among them, the construction method uses the steel frame support structure of the tunnel. The application has the effect of conveniently supporting the tunnel.

Description

technical field [0001] The present application relates to the technical field of tunnel construction, in particular to a tunnel steel frame support structure and a construction method. Background technique [0002] Our country has a vast area of ​​mountains and hills. During road construction, many related tunnel constructions will be involved. Of course, in tunnel construction, tunnel support construction is an important part of it, and it is a powerful guarantee to ensure the safety of tunnel construction. [0003] Although the existing tunnel steel frame support structure is simple in structure, many structures need to be connected by iron wire binding or welding when in use, resulting in a large amount of manpower input during construction and inconvenient use. Contents of the invention [0004] In order to support the tunnel conveniently, the present application provides a tunnel steel frame support structure and a construction method. [0005] In the first aspect, t...
