Abstract

The invention discloses a longitudinal pipe retreating type template grouting rotating device with a tunnel secondary lining separation prevention function, and relates to the technical field of tunnel secondary lining arch portion template grouting. For solving the problems that during secondary lining pouring, concrete can be solidified along with time prolonging, a grouting pipe prefabricated on the arch top is firmly bonded, and during grouting backfilling, the grouting pipe cannot be drawn out, and the device comprises a rotating mechanism and a clamping mechanism. A rotating part of therotating mechanism is fixedly connected with the clamping mechanism, when the rotating part of the rotating mechanism rotates, the clamping mechanism can be driven to rotate, the rotating mechanism isof a hollow structure, the grouting pipe can be arranged in the rotating mechanism and the clamping mechanism in a penetrating manner, and is clamped by the clamping mechanism, the design is reasonable, the structure is ingenious, operation is convenient, assembling and overhauling are facilitated, rotation of the grouting pipe can be quite conveniently achieved, due to hydraulic control, clamping force and rotating torsion are very large, site needs can be enough met, and in addition, the structure cannot affect pipeline winding due to rotation of a clamping cylinder.

Description

technical field [0001] The invention relates to the technical field of molded grouting in the arch part of the second lining of the tunnel, in particular to a tunnel secondary lining anti-vacation longitudinal retraction type belt molded grouting rotary device. Background technique [0002] The second lining of the tunnel is empty and the quality defect of the cavity is still a relatively common problem in the construction of the second lining at present. Judging from the statistical data on defect problems in the quality inspection and inspection of the previous tunnel construction process, as well as the quality inspection and acceptance of the completion of the project, there are many problems of voids and cavities in the arch part of the second lining and the arch waist, and some of the problems are serious, resulting in the safety of the design structure. Hidden dangers have a greater impact on the safety of railways, highways, and municipal roads, and have always been ...
