Abstract

The invention discloses a rotary excavating device. The rotary excavating device comprises a slicing mechanism and a conical rotary machine head cap, wherein a slurry inlet and outlet hole is formed in the side wall of the rotary machine head cap, a rotatable and telescopic connector is arranged at the tip end of the rotary machine head cap, the slicing mechanism comprises a rotary middle shaft and at least two strip-shaped slicing knives, one end of the rotating middle shaft is detachably connected with the connector, the other end of the rotating middle shaft is provided with a connecting part used for being connected with a drill rod, one end of each slicing knife is fixed to the rotating middle shaft, the other end of each slicing knife inclines towards the rotating machine head cap, and the slicing knives are distributed around the rotating middle shaft at intervals. The invention discloses a rotary excavating method. The rotary excavating method comprises the following steps that the rotary excavating device and a directional drilling machine are installed, the directional drilling machine works; connection is carried out; excavation construction is carried out; and a tube push bench retreats. According to the rotary excavating device and the rotary excavating method, a plastic drainage plate can be cut up, a pipe jacking machine tool bit is prevented from being stuck, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of drilling rigs or cutting machines, in particular to a rotary excavating device and a rotary excavating method. Background technique [0002] In urban pipe network projects, pipe jacking construction is required in many cases due to the deep burial of the pipe network and the crossing of municipal roads. During the mud-water balance pipe jacking construction, encountered the special geology of the plastic drainage board treated with the original soft foundation, the existing mud-water balance pipe jacking opportunity could not be jacked normally due to the plastic drainage board being wrapped around the pipe jacking machine cutter head, which affected the work and construction Efficiency, even, will cause the cutter head of the pipe jacking machine to be stuck in the plastic drainage board, resulting in the inability to pull out the cutter head of the pipe jacking machine, which increases the construction ...
