The MJS construction method is called an all-dimensional high-pressure injection construction method and is developed for solving the problems of slurry discharge and environmental influence in horizontal rotary injection construction; RJP is a double-high-pressure rotary spraying method, the construction efficiency is high, and the disturbance to the surrounding environment is small; currently, the mainstream MJS and RJP in the market adopt a vertical construction mode, and along with the continuous innovation of construction technology, a plurality of construction projects adopt more novel schemes of horizontal construction of the MJS and the RJP. Because the drilling tool adopts the crane hoist and mount during traditional perpendicular construction, the manual work is calibrated the drilling rod hole site, hangs and transfers the drilling rod and lean on self gravity can the cartridge target in place, then tightens up the terminal surface bolt and can construct. However, if the drill rod is horizontally constructed, the scheme is difficult to implement, the drill rod is usually horizontally placed and then lifted by a crane, workers not only need to adjust the drill rod to be in a horizontal state through manpower, but also need to ensure that the insertion of 13 insertion holes on the end face of the drill rod is completely matched, and then push the drill rod to be inserted in place in a front-back connection manner through the horizontal direction of the manpower. The drilling rod end face plug is very time-consuming and labor-consuming, and is easy to collide with the drilling rod end face plug to cause damage. In addition, after construction, the drill rod is detached more difficultly, firstly, the crane needs to assist in hanging the drill rod in a horizontal position, a worker firstly detaches four connecting bolts on the end face, the crane shakes up and down to pull the drill rods out manually or a sledge hammer blows the drill rods which are inserted into each other, so that the drill rods are very difficult to detach, and coaxial end face plugs are easily crushed and deformed, so that the drill rods cannot be reused. According to field construction statistics, the damage rate of various plugs on the end face of the disassembly drilling tool reaches 40%, the efficiency is extremely low, and the labor intensity of workers is high.

Therefore, based on the problems, the tool for disassembling the drill rod special for RJP and MJS horizontal construction is provided, which simplifies the construction labor intensity and improves the construction efficiency, and has important practical significance.
