DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1 - Figure 6 , an anchor cable high-pressure grouting control device shown in the figure includes a steel pad 1 sleeved on the outside of the steel strand and the grouting pipe, and also includes a control shell 2 sleeved on the outside of the steel strand and the grouting pipe, a clamping plate 3 adapted to the outside of the grouting pipe is arranged in the control shell 2, a connecting component 4 connected to the clamping plate 3 is installed in the control shell 2, and an adjusting part 5 fixed on the outside of the control shell 2 is used to drive the clamping plate 3 to fit toward the grouting pipe; In this solution, personnel adjust the clamping plate 3 through the adjustment part 5 so that the clamping plate 3 clamps the grouting pipe, thereby effectively connecting the slurry outlet pipe on the grouting pump with the grouting pipe. Compared with the traditional clamping method with pliers, the clamping range of the clamping plate 3 is wide and the sealing effect is better, which can avoid slurry seepage during high-pressure grouting.

[0020] For further information, see Figure 7 -Figure 9 and Figure 3 The connecting component 4 includes connecting plates 6 fixed on both sides of the clamping plate 3. Two limiting plates 7 are fixed inside the control housing 2, and a limiting post 8 is fixed between the two limiting plates 7. The connecting plates 6 on the outer side of the clamping plate 3 are located between the two limiting plates 7. A docking port 9 for slidingly docking with the limiting post 8 is formed on the outer side of the connecting plate 6, and a reset member 10 is installed between the two connecting plates 6; Among them, the reset member 10 includes a spring piece 11. The arched part of the spring piece 11 is fixed to one of the connecting plates 6, and both ends of the spring piece 11 abut against the other connecting plate 6; In this solution, when the clamping plate 3 is adjusted by the adjusting part 5, the two clamping plates 3 will move towards the grouting pipe until they abut against the outer side of the grouting pipe, so as to realize the tight docking between the slurry outlet pipe and the grouting pipe; After the grouting is completed, the operator manipulates the adjusting part 5 to cancel the force applied to the clamping plate 3, and under the action of the spring piece 11 in the reset member 10, the two connecting plates 6 are pushed apart from each other, so that the two clamping plates 3 are separated from the grouting pipe, which is convenient for the operator to pull out the slurry outlet pipe.

[0021] It should also be noted that in order to make the extrusion reset of the spring piece 11 more stable, a receiving groove 12 is formed on the adjacent side of two adjacent connecting plates 6, and the spring piece 11 is located at the receiving groove 12.

[0022] Furthermore, referring to Figure 4 - Figure 6 The adjusting part 5 includes an adjusting cylinder 13 fixed on the outer side of the control housing 2. An adjusting rod 14 is slidably inserted into the adjusting cylinder 13. An extrusion spring 15 that abuts against the adjusting rod 14 is installed in the adjusting cylinder 13. The outer end of the adjusting rod 14 is fixed with an adjusting seat 16. An adjusting opening 17 corresponding to the clamping plate 3 is formed on the control housing 2. The adjusting seat 16 is slidably inserted into the adjusting opening 17. An inclined plate 18 is fixed on the outer side of the clamping plate 3. The adjusting seat 16 is in contact with the inclined plate 18, and a locking member 19 adapted to the adjusting seat 16 is installed on the control housing 2; Among them, referring to Figure 4 and Figure 5 The locking member 19 includes a locking block 21 on the outer side of the control housing 2. A locking opening 22 is formed on the locking block 21. An adjusting plate 23 is rotatably installed on the adjusting seat 16, and the adjusting plate 23 is adapted to the locking opening 22.

[0023] In this solution, the principle of the adjusting part 5 adjusting the clamping plate 3 is as follows: First, put the control shell 2 on the outside of the steel strand. Then, during grouting, the operator inserts the slurry outlet pipe on the grouting pump into the grouting pipe. Subsequently, move the adjustment seat 16. When the adjustment seat 16 moves, it will squeeze the inclined plate 18 through the adjustment seat 16, realizing the pushing and squeezing of the clamping plate 3, making the clamping plate 3 move towards the grouting pipe and applying pressure between the slurry outlet pipe and the grouting pipe. After moving to the limit position, the operator rotates the adjustment plate 23 to insert it into the locking port 22 on the locking block 21 to complete the clamping adjustment of the clamping plate 3; When canceling the force application operation on the clamping plate 3, the operator first rotates the adjustment plate 23 to disengage from the locking port 22. Then, under the action of the compression spring 15, the push rod 14 is pushed to move outwards, so that the adjustment seat 16 retracts along the inclined plate 18 and no longer squeezes the inclined plate 18, facilitating the separation between the clamping plate 3 and the grouting pipe.

[0024] Further, refer to Figure 3 、 Figure 7 and Figure 8 There are several arc-shaped structures 29 provided on the control shell 2, and several arc-shaped structures 29 are respectively sleeved on the outside of several steel strands; In this solution, multiple arc-shaped structures 29 are sleeved on the outside of the steel strands, so as to be able to limit the steel strands, so that during subsequent high-pressure grouting, vibration between the grouting pipe and the steel strands can be avoided, and the stability during grouting can be improved.

[0025] In this solution, during the construction of drilling holes in the soil layer, the specific process of high-pressure grouting in the hole includes the following steps: The first step is that the operator first inserts the steel backing plate 1 outside the steel strand and the grouting pipe to fix its outer end; The second step is to put the control shell 2 on the outside of the steel strand and use the arc-shaped structure 29 to be sleeved with the outside of the steel strand; The third step is that the operator inserts the slurry outlet pipe on the grouting pump into the grouting pipe, and by pulling the adjustment seat 16, the adjustment seat 16 squeezes the inclined plate 18, controlling the clamping plate 3 to squeeze towards the docking place of the grouting pipe and the slurry outlet pipe to ensure the sealing performance of the docking place, and at the same time use the locking part 19 to lock and position the adjustment seat 16; The fourth step is to start grouting using the grouting pump to realize high-pressure grouting in the hole; The fifth step is that after grouting is completed, first disengage the adjustment seat 16 from the locking part 19. Then, under the action of the connecting part 4, the clamping plate 3 is separated from the grouting pipe. Then the operator withdraws the slurry outlet pipe and removes the control shell 2.

[0026] In this solution, in order to make the adjustment seat 16 adjust the inclined plate 18 more smoothly during the movement process, a roller 20 is installed on the side of the adjustment seat 16 close to the inclined plate 18, and the roller 20 is in contact with the inclined plate 18.

[0027] Embodiment 2: Please refer to Figure 5 - Figure 9 , this embodiment further illustrates Embodiment 1. The difference lies in optimizing the clamping plate 3 and adding a pressing component 24 to improve the abutting tightness between the clamping plate 3 and the butt joint of the slurry outlet pipe and the grouting pipe.

[0028] Specifically, a pressing component 24 is arranged inside the clamping plate 3. The pressing component 24 includes an airbag tube 25 arranged on the inner side of the clamping plate 3. The outer end of the adjusting cylinder 13 is fixedly communicated with an air charging pipe 26. One end of the air charging pipe 26 is fixed inside the clamping plate 3 and communicated with a plurality of airbag tubes 25. A piston plate 27 that fits against the inner wall of the adjusting cylinder 13 is fixed on the outer side of the adjusting rod 14.

[0029] It should be noted that in this solution, when the adjusting seat 16 drives the adjusting rod 14 to move, it will drive the piston plate 27 to move inside the adjusting cylinder 13, squeezing the gas inside the adjusting cylinder 13 and injecting it into a plurality of airbag tubes 25 through the air charging pipe 26. The airbag tube 25 has a certain deformation ability, so as to expand and squeeze between the clamping plate 3 and the grouting pipe, realizing the extrusion of the butt joint of the grouting pipe and the slurry outlet pipe. The clamping plate 3 is subjected to the extrusion of the inclined plate 18 when the adjusting seat 16 moves, and the secondary force of the airbag tube 25 on the clamping plate 3, so as to improve the sealing performance of the butt joint of the slurry outlet pipe and the grouting pipe; Similarly, when the adjusting seat 16 retracts and resets, the piston plate 27 correspondingly retracts, so that the airbag tube 25 correspondingly changes from expansion to deflation, realizing the detachment from the extrusion state with the grouting pipe; It should also be noted that in order to satisfy that the airbag tube 25 has a large deformation range, a groove 28 is opened on the inner side of the clamping plate 3, and the airbag tube 25 is installed in the groove 28.
