Abstract

The invention discloses a second lining grouting-with-template mechanism for a full hydraulic trolley. The second lining grouting-with-template mechanism comprises a lining trolley shell, wherein three grouting exhaust holes are formed in the lining trolley shell; the three grouting exhaust holes comprise a first grouting exhaust hole, a second grouting exhaust hole and a third grouting exhaust hole, the first grouting exhaust hole is formed in the top of the lining trolley shell, and the second grouting exhaust hole and the third grouting exhaust hole are correspondingly formed in both sidesof the bottom of the lining trolley shell; and RPC grouting pipes are arranged inside the grouting exhaust holes, and template fixing flanges are arranged at the bottom of the lining trolley shell. According to a technology, the construction is convenient and reliable, and grouting during a lining construction period does not affect the overall construction period; and the RPC grouting pipes withtemplate grouting can start grouting after initial setting of concrete, and a lining cavity is fully compacted and the lining defects are repaired through higher grouting pressure.

Description

Technical field [0001] The invention relates to the technical field of belt mold grouting, in particular to a fully hydraulic trolley second liner belt mold grouting mechanism and its grouting process. Background technique [0002] Tunnel lining vault concrete construction, due to the defects of the construction process itself, poor construction conditions, poor quality awareness of the construction personnel, and construction management problems, the tunnel lining vault voids are widespread, bringing great hazards and risks to the project, especially In the era of high-speed rail, tunnel lining diseases are more prominent. Therefore, when the defects are dealt with in the early stage of construction, that is, the embryonic stage of defects, it can significantly improve the quality of the project and ensure operational safety. [0003] Therefore, it is necessary to invent a grouting mechanism and grouting process for the second lining belt mold of a fully hydraulic trolley to solv...
