Description
Technical Field
[0001] The present application relates to the technical field of pipe racks, and in particular to a pipe rack locking connection structure. Background Art
[0002] The pipe-roof advance support method is a new technology developed in recent years for tunneling in soft surrounding rocks. The pipe-roof includes multiple grouting pipes. The support mechanism of the pipe-roof construction advance support is mainly the result of the joint action of the grouting pipe and the slurry consolidation body: on the one hand, drilling is carried out and the grouting pipe is set down. When the grouting pipe passes through the loose and weak surrounding rock, rock (soil) and other damaged areas and extends into the original soil part, it effectively guarantees the stability of the rock and soil body of the excavation face and plays the role of skeleton and grid; on the other hand, the slurry is pressed out of the grouting pipe hole through grouting, and injected into the loose and weak strata around the grouting pipe under a certain pressure, thereby forming a composite stable consolidation body, which changes the mechanical properties of the surrounding strata, strengthens the stability, and can prevent soil collapse and surface subsidence.
[0003] With regard to the above-mentioned related technologies, the inventors believe that after the grouting pipe is inserted into the drill hole, the grouting pipe serves as the main supporting skeleton of the pipe rack, but the multiple grouting pipes are independent of each other. On the one hand, the grouting pipe is easy to shake during grouting, and the stability during grouting needs to be improved. On the other hand, the stability of the overall connection of the pipe rack needs to be improved. Utility Model Content
