Abstract

The invention discloses a vault prefabricated component. The vault prefabricated component is composed of several prefabricated modules spliced ​​together. The prefabricated modules are prefabricated by construction personnel in advance according to the size of the tunnel and the strength check is completed, and then transported to the tunnel section to be constructed. Carry out splicing, guide and connect through the mortise and tenon structure during splicing. The two sides of the prefabricated modules are attached to each other through wedge surfaces, which further improves the stability of the vault prefabricated component structure. With the design of the above structure, when the tunnel roof sags, the vertical load can be decomposed along the vault prefabricated components to both sides; and with the design of the wedge surface, the vault prefabricated components are gathered towards the inner side of the tunnel when under pressure , so that the adjacent prefabricated modules fit closer together.

Description

technical field [0001] The invention relates to tunnel construction equipment, in particular to a vault prefabricated component. Background technique [0002] The tunnel concrete layer is usually constructed by lining while excavating. After the tunnel is excavated, concrete is shotcrete as primary support. Then set up the reinforcement mesh, fix the reinforcement mesh with anchor rods, and then pour the reinforcement mesh. [0003] When pouring steel mesh, formwork trolleys and pouring trolleys are usually used for construction. Before pouring, the steel mesh of the tunnel vault is welded and the template is set up by the formwork trolley. In the existing secondary lining construction technology, on-site construction personnel basically complete the welding of the steel mesh on the trolley, which has low work efficiency, high labor intensity, and there are potential safety hazards during work. Contents of the invention [0004] The present invention aims to solve at l...
