The locking frame 8 is rotatably connected with a second guide roller 93, when the insert block 9 is inserted into the locking groove 91, the locking groove 91 closes the opening of the bracket 811, the second guide roller 93 is matched with the two corresponding first guide rollers 92 to form a triangular guide hole 94, and the guide hole 94 is used for guiding the grouting pipe 14.
The implementation principle of the embodiment of the application is as follows: in the initial state, the locking cylinder 83 is in an extended state, so that the lifting rod 84 drives each lifting block 85 to be lifted, and at this time, the length direction of each locking frame 8 is parallel to the length direction of the roll-over stand 12. The two control motors 76 rotate the corresponding driving shafts 7, so that each first guide plate 72 blocks the corresponding second branch rail 64. The supporting rods 61 on the two turning seats 5 are located in the corresponding first supporting rails 63, so that the two turning seats 5 drive the corresponding clamping blocks 54 to turn ninety degrees, and at this time, each clamping block 54 is completely separated from the grouting pipe 14.
The operator controls the roll-over stand 12 to roll over by activating the electric cylinder 21 to drive the first push rod 24 and the second push rod 25, so that the roll-over stand 12 tends to be horizontal, and the operator can place the grouting pipe 14 in the opening of the roll-over stand 12. The operator places the grout tube 14 in the roll-over stand 12 so that the grout tube 14 is received on each of the first guide rollers 92. The operator is through starting locking cylinder 83 for the piston rod shrink of locking cylinder 83 drives lifter 84 to remove, thereby drives each locking frame 8 upset, makes the inserted block 9 on each locking frame 8 all insert in the locking groove 91 that corresponds. At this time, the second guide rollers 93 on the respective locking frames 8 are abutted against the grouting pipe 14, and play a role in limiting and guiding the grouting pipe 14.
Then, the operator starts the driving motor 43 to drive the corresponding chain wheel 41 to rotate, and further drives the chain 42 to move, so that the two movable bases 4 move to one end of the guide rail 62 far away from the second branch rail 64. In this process, each support rod 61 all slides gradually to the corresponding guide rail 62 in for two upset seats 5 drive corresponding grip blocks 54 all towards grouting pipe 14 direction upset ninety degrees, and grouting pipe 14 is located between two grip blocks 54 that same upset seat 5 corresponds this moment. Then the operator starts the two finger cylinders 53 to drive the corresponding clamping blocks 54 to clamp the grouting pipe 14, so as to fix the grouting pipe 14.
After the grouting pipes 14 are fixed, the operator starts the two control motors 76 to drive the driving shaft 7 to rotate, so that the first guide plates 72 release the limiting effect on the second branch rails 64, and the second guide plates 73 are turned over to block the first branch rails 63. At this time, the guide rail 62 communicates with the second branch rail 64.
Before inserting the grouting pipe 14 into the sleeve valve pipe, starting the electric cylinder 21 to drive the overturning frame 12 to overturn until the grouting pipe 14 is approximately parallel to the sleeve valve pipe, and finely adjusting the overturning angle of the overturning frame 12 by rotating the screw sleeve 26 to enable the grouting pipe 14 to be parallel to the sleeve valve pipe. The operator then moves the mobile carrier 1 so that the grout tube 14 is aligned with the sleeve valve tube.
When the operator controls the grouting pipe 14 to be inserted into the sleeve valve pipe, the operator firstly starts the finger air cylinder 53 corresponding to the second clamping jaw 52 to release the clamping effect on the grouting pipe 14. The operator then actuates the drive motor 43 a nominal number of turns so that the first jaw 51 moves a set distance toward the hinge axis 13 and the second jaw 52 moves the same distance away from the hinge axis 13 to effect movement of the grout tube 14 a set distance toward the sleeve valve tube. The operator activates the finger cylinder 53 corresponding to the second clamping jaw 52 to clamp the grouting pipe 14, and then activates the finger cylinder 53 corresponding to the first clamping jaw 51 to release the clamping effect on the grouting pipe 14. Finally, the operator starts the driving motor 43 to rotate reversely for a rated number of turns, so that the first clamping jaw 51 moves for a set distance in the direction away from the hinge shaft 13, and the second clamping jaw 52 moves for the same distance in the direction toward the hinge shaft 13, thereby realizing that the grouting pipe 14 continues to move for a certain distance toward the sleeve valve pipe. The operator repeats the above-described operation, so that the grouting pipe 14 moves into the sleeve valve pipe in a walking manner.
After the grout tube 14 completes a section of grouting, the operator needs to lift the grout tube 14 a distance. An operator drives the grouting pipe 14 to lift in a walking way by matching the driving motor 43 with the two finger cylinders 53, so that layered grouting is realized.
The embodiment of the application further discloses a multi-section sleeve valve pipe layered grouting method, which comprises the following steps:
s1: planning and measuring, namely measuring on the ground in the to-be-constructed range through a total station, planning drilling positions, drilling quantity and drilling depth, and setting reasonable hole intervals.
S2: and (3) drilling construction, wherein an operator drills holes at the positions provided with the marks on the ground through the drilling device, and the drilling depth is controlled in the drilling process.
And S3, a sleeve valve pipe is arranged, a conical head is arranged at the bottom of the prepared sleeve valve pipe, and the sleeve valve pipe provided with the conical head is inserted into each hole, so that the opening end of each sleeve valve pipe is 15-30cm higher than the ground.
And S4, hole sealing construction, namely preparing concrete by an operator, sealing the concrete in a range from the ground around the hole opening to 0.5-1m below the ground, and preventing slurry from overflowing from the space between the hole wall and the outer wall of the sleeve valve pipe when grouting is prevented by the concrete.
And S5, layered grouting, namely, an operator firstly installs the grouting pipe 14 in the roll-over stand 12 and limits and guides the grouting pipe 14 through the matching of each second guide roller 93 and the corresponding first guide roller 92. An operator controls the driving motor 43 to drive the corresponding chain wheel 41 to rotate, so as to drive the first clamping jaw 51 and the second clamping jaw 52 to reversely lift under the action of the chain 42, and then the first clamping jaw 51 and the second clamping jaw 52 are in elastic fit to clamp the grouting pipe 14, so as to drive the grouting pipe 14 to lift in a walking manner.
After the grouting pipe 14 is installed on the roll-over stand 12, an operator drives the first push rod 24 and the second push rod 25 to push the roll-over stand 12 to roll over by starting the electric cylinder 21, the angle of the grouting pipe 14 is controlled, and the carrier 1 is moved to align the grouting pipe 14 with the corresponding sleeve valve pipe so that the grouting pipe 14 extends into the sleeve valve pipe.
An operator presses the grout into the gap between the grouting pipe 14 and the sleeve valve pipe through a grouting pump, so that the grout is injected into the rock-soil layer through the grout outlet of the sleeve valve pipe. After finishing the first-stage grouting, the operator controls the driving motor 43 to cooperate with the first clamping jaw 51 and the second clamping jaw 52 to drive the grouting pipe 14 to lift a preset distance for continuous grouting, and the segmented grouting is realized in such a reciprocating manner.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
