It connects；Well-flushing dreg removing system includes Pulp pump and mud channel, and Pulp pump is fixedly mounted on the main drive of shaft excavation machine
The upper end in portion, mud channel is connected by the pulp absorbing hole of the first swivel joint and Pulp pump, and the lower end of mud channel sequentially passes through
One end of three-way connection is connected after main drive, drill boom, the other both ends of three-way connection are connected separately with branch line, and pair is driven
Second swivel joint is installed, the lower end of branch line passes through the company in the second swivel joint and assistant drive device at the top of dynamic device
One end connection is taken over, the connecting tube other end is connected with distribution pipeline by tap after assistant drive device, drilling tool, shunts
The lower end of pipeline is connect with multiple slag suction mouths of drilling tool lower part.
The well-flushing dreg removing system matched with sinking method shaft excavation machine, the outlet end of Pulp pump passes through discharge pipe
It is connect with the mud and water separating equipment on ground.
Due to the adoption of the technical scheme as described above, the present invention has the following advantages:
It is somebody's turn to do well-flushing dreg removing system matched with sinking method shaft excavation machine, structure is simple, and rate of penetration is not limited by slagging tap,
Direct deslagging is carried out by Pulp pump, and slag discharge amount is adjusted by control Pulp pump operating parameter, is inhaled and is followed using Pulp pump pump
Broken ground is transported to outside well by mud as carrier by ring in time, and mud is returned in well and recycled again after separation
It uses, effectively increases well-flushing efficiency, improve the drilling efficiency and drill tool life of development machine, improve production efficiency.
Should well-flushing dreg removing system matched with sinking method shaft excavation machine, use in well that hydraulic pressure is put down around mud and vertical shaft
The principle of weighing apparatus, playing the role of retaining wall without section of jurisdiction position in shaft bottom prevents from collapsing, and with traditional sinking shaft arrangement and method for construction analogy, does not need
Special sealing and waterproof process are carried out around vertical shaft, and gib operation in the process, effectively reduce and be constructed into
This, shortens the construction period.
