Abstract

The invention discloses a construction method and equipment for cutting a deep-buried structure with a small-caliber drill tool and relates to the field of deep-buried structure cutting construction. In the method, by filling and pouring concrete in the deep-buried structure, digging a cutting slot above the deep-buried structure, pouring bottom plate concrete in the cutting slot and adopting a method for positioning a drill rod by a positioning frame, the accurate cutting of the deep-buried structure by using the small-caliber drill tool is realized, the construction cost is reduced and the construction period is shortened. The high-precision positioning frame ensures the drill rod operates at a position required in design, so that the drill rod can only operate between four adjacent guide rods without deflection. Guide rods are arranged on both sides of a positioning frame to improve the success rate of the cutting construction.

Description

technical field

[0001] The invention relates to the construction field of cutting deep-buried structures, in particular to a construction method and equipment for cutting deep-buried structures with a small-diameter drilling tool. Background technique

[0002] At present, in the construction of underground engineering projects, the demolition and reconstruction of pile foundations of original buildings, waste underground pipelines, and damaged underground structures, as well as the disposal of underground structures encountered in the construction of new projects. Shallow obstacles can be cleared by excavation, or extracted from the ground. For underground structures with a large buried depth, special construction methods are required to deal with them. To cut underground structures, the excavation method requires a huge amount of construction, and the construction cost is too high, while cutting with small-diameter drilling tools has the problem that it is easy to deflect d...
