[0002] The tunnel is a passageway drilled between the surface and the ore body, used for ore transportation, ventilation, drainage, pedestrians, and various necessary preparations for the new excavation of ore for metallurgical equipment. These passageways are collectively referred to as tunnels. The tunnel is a passageway drilled between the surface and the ore body, used for ore transportation, ventilation, drainage, pedestrians, and various necessary preparations for the new excavation of ore for metallurgical equipment. These passageways are collectively referred to as tunnels. The tunnel grouting refers to the grouting work carried out for water blocking or reinforcement of horizontal tunnels, inclined tunnels, main stone gates and large chambers in underground projects when they pass through fault fracture zones, fissure aquifers, quicksand layers or caving fracture zones.

[0003] The existing tunnel grouting reinforcement structure, when in use, usually uses a grouting gun, which is inserted into a grouting hole drilled in advance and connected to the gap, and then the grouting pump is connected to perform grouting. Since a large pressure is required during grouting, the connection between the grouting pump and the grouting hole needs to be tighter to effectively increase the firmness of the grouting gun. Therefore, the connection stability during grouting is particularly important. Therefore, a tunnel grouting reinforcement structure is urgently needed to solve the above problems.
