Specific implementation mode
Specific embodiment of the present utility model is described in further details below in conjunction with attached drawing 1-6.
It being provided by Fig. 1-6, the utility model includes multiple sequentially connected casings 1, and the front and back of casing 1 is equipped with interconnecting piece 2,
Interconnecting piece 2 is extended with locating piece 3 upwards, and the rear end of casing 1 is equipped with locating slot 4, and locating piece 3 constitutes adjacent with the cooperation of locating slot 4
The structure of 1 axial restraint of casing, pipe 5 is interior to be equipped with Grouting Pipe, and the both ends of Grouting Pipe are equipped with quick coupling, adjacent Grouting Pipe warp
Quick coupling connects, and the Grouting Pipe on casing 1 being connected with drill bit is connected with nozzle, during drilling, spreading casing 1
And Grouting Pipe carries out slip casting into hole in drilling if it find that when aperture has silt particle, water to emerge in large numbers as occurring, it will be on casing
Grouting Pipe is connect with slip casting machine through-hole quick coupling, the then slip casting into hole, has just started all to inject cement mortar in two Grouting Pipes,
Cement mortar is ejected in hole from nozzle and is pressed into stratum after mixing, and waterglass slurry will be injected in one of Grouting Pipe, is accelerated
The solidification of cement mortar, to achieve the effect that strengthening stratum and water blockoff, can in time to gushing silt particle, water burst situations such as carry out it is timely
Processing, avoid the generation of safety accident；
After the completion of stratum consolidation and water blockoff, the water filling into Grouting Pipe by slip casting machine, detergent line after the completion of drilling, is moved back
Grouting Pipe also exits while going out casing, and Grouting Pipe is taken out out of pipe 5 and is cleaned, and ensures to can continue to when next slip casting
It uses.
The width of locating slot 4 is more than the width of location hole so that locating piece 3 is in locating slot 4 when the generation angle change of casing 1
It is interior to be subjected to displacement rather than fixed, avoid the damage of location structure so that casing 1 can generate the change of angle
Change；
The front end of casing connects drill bit, and the rear end of casing connects drilling machine, and drilling machine drives casing and drill bit rotation and to being pushed forward
Into the quantity of selection casing 1 is attached as needed, and casing 1 is hollow structure, and hollow structure is logical as the pressure in drilling
Road is passed through high pressure water or mud into hollow casing 1, the ground in drill bit is gone out, the front end of casing 1 is set in drilling
There are link slot 6, the rear end of casing 1 to be equipped with conical head 7, conical head 7 is equipped with connector 8, and connector 8 is inserted into link slot 6 will
Connected casing 1 connects, and the structure of conical head 7 so that two connected casings 1 connect adjustable angle, can be adjusted in drilling
Angle.
Adjacent 1 junction of casing is equipped with sealing ring, and sealing ring is mounted on the connector 8 of casing 1, by adjacent casing
Gap between 1 is filled up, and avoids leaking in high pressure, and conical head 7 can facilitate the rotation between adjacent casing 1, even
The linear structure of connector 8.Facilitate the gap between sealing adjacent casing 1, it is made to remain able to play the work of sealing in rotation
With.
The outermost of pipe 5 is no more than the outermost of locating piece 3, and casing can carry out pipe 5 during rotation
It is effectively protected, avoids pipe 5 from directly being collided with hole, reduce the failure rate of equipment.
Multiple connecting rods 9 are extended with outside casing 1, the connecting rod 9 between adjacent casing 1 is connected through connecting plate 10, connecting rod 9
The radially connected structure of adjacent casing 1 is connected and composed through connecting plate 10.
Opening diameter on connecting plate 10 is more than the diameter of connecting rod 9, while playing connection function, will not say that it is tight
Close connection so that still can generate small change in displacement between adjacent casing 1, small angle change can be generated.
Screw thread is equipped in connecting rod 9, connecting rod 9 stops connecting plate 10 from connecting rod 9 through being threadedly coupled screw 11, screw 11
On fall off.
The utility model timely slip casting of energy during drilling, effectively prevents soil erosion in stratum, controls very well
Stratum deformation has been made, ensure that earth's surface is built（Structure）The safety of object；Drilling and two processes of slip casting be combined into one, reduce process,
The time of construction is saved；Slip casting has specific aim, and the location progress slip casting for only occurring water burst, gushing silt particle reduces big face
