DETAILED DESCRIPTION

[0030] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and apparently, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range protected by the utility model.

[0031] Please refer to Figures 1-5 A kind of grouting hole sealing device, comprising:

[0032] Grouting pipe 1, grouting cavity 2 is set in its inside, the outer wall of grouting pipe 1 is set with multiple grouting holes 3, which communicate with grouting cavity 2;

[0033] A liquid storage tank 4 is arranged at the bottom of the grouting pipe 1, and the chemical solution is stored in the liquid storage tank 4. A cotton ball 5 is arranged at the bottom of the liquid storage tank 4.

[0034] A connecting component 6 is arranged in the interior of the liquid storage tank 4, and is used to connect the liquid storage tank 4 and the grouting pipe 1.

[0035] The grouting pipe 1 can be made of PE material. The grouting pipe 1 made of PE material can be integrally formed. The compressive capacity meets the requirements and there is no joint. The situation that the thread at the joint falls off when the pipe is pulled out is avoided, and the quality of grouting is improved.

[0036] In use, the grouting pipe 1 is gradually put into the borehole, and the grouting pipe 1 moves together with the liquid storage tank 4 and the cotton ball 5. After moving to the corresponding position, the grouting material is poured into the grouting pipe 1. Then the grouting material enters the grouting cavity 2 and flows out of the borehole through the grouting holes 3. Since the density of the grouting material is greater than that of water, the water above the grouting point is discharged outward during grouting, thereby achieving the effect of full-hole sealing. The plurality of grouting holes 3 is to prevent the single grouting hole 3 from being blocked and causing grouting failure. Meanwhile, the multi-directional grouting holes 3 can make the slurry in the borehole rise synchronously, so that the grouting effect is more uniform and stable.

[0037] The liquid storage tank 4 and the cotton ball 5 are moved to the leakage point position through the grouting pipe 1. The cotton ball 5 is attached to the inner wall of the borehole. The chemical solution in the liquid storage tank 4 enters the cotton ball 5. Then the chemical solution diffuses in the cotton ball 5. After that, the chemical solution hardens the cotton ball 5 and makes it adhere to the borehole, thereby achieving the effect of plugging the leakage point and preventing the grouting material from seeping out. The leakage point will not release the grouting pressure to affect the grouting effect. Compared with the traditional use of a grouting plug for blocking, the cotton ball 5 is more flexible. When moving in the borehole, the cotton ball 5 reduces the friction with the inner wall of the borehole by deformation. The cotton ball 5 can move more smoothly in the borehole. The cotton ball 5 can smoothly reach the plugging position of the leakage point. The cotton ball 5 can achieve the effect of preventing the grouting material from leaking at the predetermined position. The cotton ball 5 can effectively plug and has good use effect.

[0038] For example, the chemical solution in the liquid storage tank 4 can be water glass solution. The water glass solution has good adhesion and anti-seepage properties. The water glass solution in the liquid storage tank 4 flows into the cotton ball 5, so that the content of the water glass solution in the cotton ball 5 is sufficient, and the plugging effect after the water glass hardens is ensured. Before installing the cotton ball 5, the cotton ball 5 can also be soaked in the water glass solution to further increase the anti-leakage performance.

[0039] The connecting part 6 is a temporary fixing structure connecting the liquid storage tank 4 and the grouting pipe 1. When the grouting pipe 1 drives the liquid storage tank 4 and the cotton wad 5 to move, the connecting part 6 ensures that the liquid storage tank 4 is not separated from the grouting pipe 1. When the grouting is completed, due to the pressure of the grouting material and the gravity of the liquid storage tank 4, the connecting part 6 is separated from the grouting pipe 1 when the grouting pipe 1 is pulled out upward, so that the liquid storage tank 4 and the cotton wad 5 are left in the borehole to form an integral whole. The current grouting plug is not convenient to separate, and the operation is simple and has high practicability.

[0040] In the embodiment, referring to Figures 3-5 , a limiting ring groove 7 is formed in the inner wall of the grouting cavity 2, and the connecting part 6 comprises:

[0042] a rubber block 62 arranged on one side of the clamping piece 61 facing the inner wall of the liquid storage tank 4 and matched with the limiting ring groove 7.

[0043] In this way, when the liquid storage tank 4 is connected with the grouting pipe 1, the bottom of the grouting pipe 1 is inserted into the liquid storage tank 4, the inner wall of the grouting pipe 1 causes the clamping piece 61 to deform and extrudes the rubber block 62 to deform, the rubber block 62 is located in the limiting ring groove 7 when the grouting pipe 1 is moved to the position, and the rubber block 62 restores the deformation to enter the limiting ring groove 7, so that the grouting pipe 1 is preliminarily limited by the cooperation of the rubber block 62 and the limiting ring groove 7, and the clamping piece 61 also clamps the inner wall of the grouting cavity 2, so that the grouting pipe 1 is ensured not to be separated when driving the liquid storage tank 4 to move downward. When the subsequent grouting is completed, due to the pressure of the grouting material and the gravity of the liquid storage tank 4, the liquid storage tank 4 is subjected to a large downward pulling force, and when the grouting pipe 1 is pulled upward, the grouting pipe 1 extrudes the rubber block 62, the rubber block 62 is finally separated from the limiting ring groove 7, and the grouting pipe 1 is separated from the liquid storage tank 4 after the grouting pipe 1 is continuously pulled upward, so that the liquid storage tank 4 and the cotton wad 5 are left in the borehole.

In this way, the cotton wad 5 is fixed by the pressing piece 8, the leakage hole on the pressing piece 8 is communicated with the cotton wad 5, the chemical solution in the liquid storage tank 4 enters the cotton wad 5 through the leakage hole of the pressing piece 8, and the cotton wad 3 is better bonded in the borehole.

[0046] In this way, when the grouting feeding is completed, the vibrating head 10 is started to vibrate the bottom of the grouting pipe 1, and then the grouting pipe 1 is gradually pulled out upwards, and the vibration of the grouting pipe 1 can make the grouting material more compact, reduce the air bubbles in the grouting material, and improve the quality of the drilling plugging.

[0047] Preferably, referring to Figure 3 The inner wall of the grouting cavity 2 is annularly provided with a plurality of buffer pieces 12 in a downwardly inclined state. In this way, the buffer pieces 12 are used to slow down the falling speed of the grouting material in the grouting cavity 2, so that the grouting material moves downward at a gentle speed, and the possibility of segregation of the grouting material caused by high-speed falling is reduced.

[0048] Preferably, referring to Figures 1-2 The outside of the grouting pipe 1 is detachably provided with two hoop bodies 13, the hoop bodies 13 are provided with supporting blocks 14, and auxiliary wheels 15 are rotatably arranged on the supporting blocks 14.
