Between can mutually be rotated around the central axis of rotary pile-digging machine drilling rod 31, rotary pile-digging machine drilling rod 31 rotate when, shell 26, energy storage storehouse 25,
The high-pressure hose 2 of stone rotary digging drill bit 1 is cut in wound around coil 27 and connection and pile digger drilling rod 31 rotates synchronously, and upper cover 24, compression
Block 29, sealing bolt 30 are then stationary, and pile digger drilling rod 31 is not followed to rotate.
Embodiment 3
When encountering erratic boulder using 5 pore-forming of rotary pile-digging machine, rotary pile-digging machine 5 promotes drilling pipe, is then filled using the utility model
It sets and carries out erratic boulder processing.
On the basis of above-mentioned two embodiment, connection side 12 is connect with rotary pile-digging machine drilling rod 31 first, will also be cut
Stone rotary digging drill bit 1 is mounted on rotary pile-digging machine drilling rod 31, and pomegranate sand is filled in pomegranate sandbox.According to stake holes diameter tune
Main auger spindle 13 is saved, the operating radius of locating rod 14 is made to be slightly less than stake holes radius, operates the decentralization decentralization rotary digging stake of rotary pile-digging machine 5 later
Driver drilling rod 31 and stone rotary digging drill bit 1 is cut, when the shield 16 for cutting stone rotary digging drill bit 1 touches erratic boulder, stops decentralization, by rotary digging stake
Driver drilling rod 31 is lifted up 8cm~10cm.
Then light water is pressurized to 200MPa~300MPa and is conveyed by high-pressure hose 2 supreme by starting high pressure pump truck 3
Cutting bit 7 is pressed, at this time under the action of high pressure water suction force, hard sand is delivered to high-pressure cutting drill bit 7 by hard sand conduit 9
And it is mixed to form high-pressure water jet with high pressure water, it cuts stone rotary digging drill bit 1 and the rotation of rotary pile-digging machine drilling rod 31 is followed to cut erratic boulder
It cuts.After cutting 1 circumgyration incision 1~2 of stone rotary digging drill bit circle, promotion cuts stone rotary digging drill bit 1 to earth's surface, adjusts main auger spindle 13, it is fixed to reduce
The operating radius of position bar 14 repeats the above process and continues to cut erratic boulder.
After erratic boulder is crushed to a certain extent, rotary pile-digging machine uses normal drill bit instead and promotes rubble, completes the place of erratic boulder in stake holes
Reason.Rotary pile-digging machine drilling rod 31 is promoted at this time, cuts stone rotary digging drill bit 1 with changing, and is transferred conventional bit, is taken out broken erratic boulder.
Further, the winding-resisting device 4 works as follows.Before stone rotary digging drill bit 1 is cut in installation, first anti-
Wrapping head 4 is inserted in from the head position of rotary pile-digging machine drilling rod 31, when rotary pile-digging machine drilling rod 31 slowly transfers to stake holes, uses steel
Pipe or reinforcing bar lift winding-resisting device 4 in earth's surface, while the high-pressure hose 2 in wound around coil 27 being followed and cuts stone rotary digging drill bit 1
It transfers together；Rotary pile-digging machine drilling rod 31 is transferred to when cutting stone 1 operating position of rotary digging drill bit, and winding-resisting device 4 is raised, and makes its distance ground
Table 30cm~50cm, and slightly tense high-pressure hose 2.Then hold-down bolt 28 is tightened, winding-resisting device 4 is fixed on rotary pile-digging machine
On drilling rod 31, install.
When high pressure pump truck 3 works, high pressure water is delivered to energy storage storehouse 25 by high-pressure hose 2, and down through energy storage storehouse 25
It is delivered to high-pressure water tank 10.When rotary pile-digging machine drilling rod 31 rotates, shell 26, energy storage storehouse 25, wound around coil 27 and its underpart are high
Pressure hose 2 follows rotary pile-digging machine drilling rod 31 to rotate together, but the high-pressure hose 2 of upper cover 24 and its top is then stationary, not with
It is rotated with rotary pile-digging machine drilling rod 31.
Before the promotion of rotary pile-digging machine drilling rod 31, hold-down bolt 28 is unclamped, winding-resisting device 4 is no longer secured to rotary pile-digging machine drilling rod
On 31, rotary pile-digging machine drilling rod 31 can be promoted, while the high-pressure hose 2 of 4 lower part of winding-resisting device is followed rotary pile-digging machine drilling rod 31
It is promoted to earth's surface together.
Further, the high pressure pump truck 3 works as follows.Firstly, access power supply, opens opening on control cabinet 18
Dynamic switch, driving motor 19 starts and works under the action of circuit control system, while booster 21 is in driving motor 19
It also starts to work under effect, water tank 20 is that booster 21 provides water source, and the high pressure water that booster 21 exports is stored to energy-storage box 22.
22 pressure regulating switch of energy-storage box is adjusted, by high water pressure setting to 200MPa~300MPa.The pressure of setting is believed
It number will be transmitted to signal processing system, signal processing system is handled according to the pressure signal analysis in energy-storage box 22, when hydraulic pressure is big
When setting pressure, driving motor 19 stops working, and when hydraulic pressure is lower than setting pressure, driving motor 19 restarts work.
When high pressure water in energy-storage box 22 reaches setting pressure, high-pressure cutting drill bit 7 is delivered to by high-pressure hose 2.
Above embodiments are only to illustrate the technical solution of the utility model, rather than are limited；Although referring to before
Embodiment is stated the utility model is described in detail, it for those of ordinary skill in the art, still can be right
Technical solution documented by previous embodiment is modified or equivalent replacement of some of the technical features；And these
Modifications or substitutions, the utility model technical solution claimed that it does not separate the essence of the corresponding technical solution spirit and
Range.
