Abstract

The invention discloses a resistance-reducing type slurry hole drilling device for a large-diameter jacking pipe and a construction method thereof, and belongs to the technical field of processing of steel jacking pipes. The resistance-reducing type slurry hole drilling device for the large-diameter jacking pipe comprises rolling mechanisms, a hole drilling mechanism and a control unit, wherein each rolling mechanism comprises a driving mechanism, a transmission mechanism, two supporting frames arranged on a supporting base, and rollers; the hole drilling mechanism comprises a lifting mechanism and a hole driller; the control module comprises a roller control module, a lifting mechanism control module and a hole driller control module. With the adoption of the resistance-reducing type slurry hole drilling device for the large-diameter jacking pipe, a hole can be automatically drilled in the jacking pipe. The device has the advantages of being simple in structure, convenient to operate, and high in construction efficiency. The invention also provides a construction method of the resistance-reducing type slurry hole drilling device for the large-diameter jacking pipe. The construction method is simple to operate, and high in slurry hole quality.

Description

technical field [0001] The invention relates to a large-diameter pipe jacking drag-reducing mud hole drilling device and a construction method thereof, belonging to the technical field of steel pipe jacking. Background technique [0002] Pipe jacking construction is an underground engineering construction method developed after shield construction, mainly used for the construction of underground water inlet pipes, drainage pipes, gas pipes, and telecommunication cable pipes. The pipe jacking construction is to set the originating well and the receiving well, and use the main jacking device to push the pipe jacking from the originating well to the receiving well. Commonly used pipes are reinforced concrete pipes, steel pipes, and glass fiber reinforced plastic jacking pipes. [0003] In order to reduce the resistance during the pushing of the jacking pipe, a mud hole is set on the jacking pipe, and the mud is pressed out from the mud hole by the grouting device, and a mud sl...
