Description

Technical Field

[0001] The invention relates to the technical field of anchor cable high-pressure grouting, in particular to an anchor cable high-pressure grouting control device. Background Art

[0002] Anchor cable high-pressure grouting is to inject slurry with a certain pressure into the anchor cable drill hole through the grouting pipe. The slurry penetrates into the pores and cracks of the surrounding rock and soil under the action of pressure. After the slurry solidifies, the anchor cable and the rock and soil are tightly bonded together to form a whole, thereby improving the strength and stability of the rock and soil and enhancing the anchoring force of the anchor cable.

[0003] Currently, before high-pressure grouting, personnel will first lower the anchor cable into the bottom of the hole, and then connect the grouting pipe in the anchor cable through the grouting pipe on the grouting pump. Then, they will use pliers to clamp the joint between the grouting pipe and the grouting pipe, and then start grouting. However, during high-pressure grouting, the grouting pressure will change, which will cause the pipeline to vibrate. The clamping range of the pliers is narrow, and it is easy to loosen due to vibration, which will cause slurry to seep out during high-pressure grouting. Summary of the Invention

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1 - Figure 6 The figure shows an anchor cable high-pressure grouting control device, comprising a steel plate 1 sleeved on the outside of the steel strand and the grouting pipe, and 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 provided 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 portion 5 fixed to the outside of the control shell 2 is used to drive the clamping plate 3 to fit toward the grouting pipe;

[0030] 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 of pliers, the clamping plate 3 has a wide clamping range and a better sealing effect, which avoids slurry leakage during high-pressure grouting.

[0031] For further information, see Figure 7 - Figure 9 and Figure 3 The connecting component 4 includes a connecting plate 6 fixed on both sides of the clamping plate 3, two limit plates 7 are fixed in the control housing 2, and a limit column 8 is fixed between the two limit plates 7. The connecting plate 6 on the outside of the clamping plate 3 is located between the two limit plates 7. A docking port 9 is provided on the outside of the connecting plate 6 for sliding docking with the limit column 8. A reset member 10 is installed between the two connecting plates 6;

[0032] The reset member 10 includes a spring sheet 11, the arch of the spring sheet 11 is fixed to one of the connecting plates 6, and the two ends of the spring sheet 11 are against the other connecting plate 6;

[0033] In this solution, when the clamping plates 3 are adjusted by the adjusting portion 5, the two clamping plates 3 will move toward the grouting pipe until they are pressed against the outside of the grouting pipe, thereby achieving a tight connection between the slurry outlet pipe and the grouting pipe;

[0034] After the grouting is completed, the personnel manipulates the adjustment part 5 to cancel the force on the clamping plate 3, and under the action of the spring sheet 11 in the reset member 10, pushes the two connecting plates 6 apart from each other, so that the two clamping plates 3 are separated from the grouting pipe, making it easier for the personnel to pull out the slurry outlet pipe.

[0035] It should also be noted that, in order to make the extrusion and reset of the spring piece 11 more stable, receiving grooves 12 are opened on adjacent sides of two adjacent connecting plates 6 , and the spring piece 11 is located in the receiving grooves 12 .

[0036] For further information, see Figure 4 - Figure 6 The adjusting portion 5 includes an adjusting cylinder 13 fixed to the outside of the control housing 2, an adjusting rod 14 is slidably inserted in the adjusting cylinder 13, an extrusion spring 15 is installed in the adjusting cylinder 13 and abuts against the adjusting rod 14, an adjusting seat 16 is fixed to the outer end of the adjusting rod 14, an adjusting port 17 is opened on the control housing 2 corresponding to the clamping plate 3, the adjusting seat 16 is slidably inserted in the adjusting port 17, an inclined plate 18 is fixed on the outside of the clamping plate 3, the adjusting seat 16 is fitted with the inclined plate 18, and a locking member 19 adapted to the adjusting seat 16 is installed on the control housing 2;

[0037] Among them, see Figure 4 and Figure 5The locking member 19 includes a locking block 21 on the outside of the control housing 2 , a locking opening 22 is provided on the locking block 21 , and an adjusting plate 23 is rotatably mounted on the adjusting seat 16 , and the adjusting plate 23 is adapted to the locking opening 22 .

[0038] In this solution, the principle of the adjustment part 5 adjusting the clamping plate 3 is as follows:

[0039] First, the control housing 2 is put on the outside of the steel strand. Then, during grouting, the personnel insert the slurry outlet pipe on the grouting pump into the grouting pipe. Subsequently, the adjusting seat 16 is moved. When the adjusting seat 16 moves, the inclined plate 18 is squeezed by the adjusting seat 16 to push and squeeze the clamping plate 3, so that the clamping plate 3 moves toward the grouting pipe and applies pressure between the slurry outlet pipe and the grouting pipe. After moving to the extreme position, the personnel rotate the adjusting plate 23 to plug it into the lock port 22 on the locking block 21 to complete the clamping adjustment of the clamping plate 3.

[0040] When canceling the force operation on the clamping plate 3, the personnel first rotate the adjustment plate 23 to disengage the lock 22, and then push the adjustment rod 14 outward under the action of the extrusion spring 15, so that the adjustment seat 16 retreats along the inclined plate 18 and no longer squeezes the inclined plate 18, thereby facilitating the separation between the clamping plate 3 and the grouting pipe.

[0041] For further information, see Figure 3 、 Figure 7 and Figure 8 , a plurality of arc structures 29 are provided on the control housing 2, and the plurality of arc structures 29 are respectively sleeved on the outside of the plurality of steel strands;

[0042] In this solution, multiple arc structures 29 are used to cover the outside of the steel strands, so as to limit the steel strands, so that during subsequent high-pressure grouting, vibration between the grouting pipe and the steel strands can be avoided, thereby improving the stability during grouting.

[0043] In this solution, during the soil drilling construction, the specific process of high-pressure grouting in the hole includes the following steps:

[0044] In the first step, the personnel first insert the steel plate 1 into the outside of the steel strand and the grouting pipe to fix its outer end;

[0045] The second step is to put the control housing 2 on the outside of the steel strand and use the arc structure 29 to connect with the outside of the steel strand;

[0046] In the third step, the personnel insert the slurry discharge pipe on the grouting pump into the grouting pipe, and pull the adjusting seat 16 so that the adjusting seat 16 squeezes the inclined plate 18, controls the clamping plate 3 to squeeze toward the joint between the grouting pipe and the slurry discharge pipe to ensure the sealing of the joint, and uses the locking member 19 to lock the adjusting seat 16 in place;

[0047] The fourth step is to start grouting using a grouting pump to achieve high-pressure grouting in the hole;

[0048] Step 5. After the grouting is completed, first disengage the adjustment seat 16 from the locking member 19, and then, under the action of the connecting component 4, disengage the clamping plate 3 from the grouting pipe. Then, the personnel pull out the slurry pipe and remove the control shell 2.

[0049] In this solution, in order to enable the adjustment seat 16 to adjust the inclined plate 18 more smoothly during movement, 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.

[0050] Example 2: Please refer to Figure 5 - Figure 9 This embodiment further explains the first embodiment. The difference lies in that the clamping plate 3 is optimized and a tightening component 24 is added to improve the sealing performance of the clamping plate 3 against the joint between the slurry outlet pipe and the grouting pipe.

[0051] Specifically, a clamping component 24 is provided in the clamping plate 3, and the clamping component 24 includes an airbag tube 25 provided on the inner side of the clamping plate 3. The outer end of the adjusting cylinder 13 is fixedly connected to an inflation tube 26. One end of the inflation tube 26 is fixed in the clamping plate 3 and is connected to several airbag tubes 25. A piston plate 27 that fits with the inner wall of the adjusting cylinder 13 is fixed to the outer side of the adjusting rod 14.

[0052] It should be noted that, in this solution, when the adjusting seat 16 drives the adjusting rod 14 to move, it drives the piston plate 27 to move in the adjusting cylinder 13, squeezing the gas in the adjusting cylinder 13 and injecting it into the multiple airbag tubes 25 through the inflation tube 26. The airbag tubes 25 have a certain deformation capacity, thereby expanding and squeezing between the clamping plate 3 and the grouting pipe, thereby squeezing the grouting pipe and the slurry discharge pipe at the joint. The clamping plate 3 is squeezed by the inclined plate 18 when the adjusting seat 16 moves, and the secondary force applied by the airbag tubes 25 to the clamping plate 3, thereby improving the sealing performance of the joint between the slurry discharge pipe and the grouting pipe.

[0053] Similarly, when the adjustment seat 16 retreats and resets, the piston plate 27 retreats accordingly, so that the airbag tube 25 correspondingly changes from expansion to deflation, thereby achieving separation from the squeezed state between the airbag tube and the grouting tube;

[0054] It should also be noted that, in order to satisfy the requirement that the airbag tube 25 has a larger 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 .

[0055] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
