Description

Technical Field

[0001] The utility model relates to the technical field of injection blocking, in particular to a blocking device for a leakage repair injection port. Background Art

[0002] Buildings (such as masonry buildings or concrete buildings) will have leakage or cold weather problems after a certain period of time. At this time, it is necessary to use grouting to repair them. During the grouting process, a blocking device needs to be filled in the grouting hole to improve the sealing of the hole during the grouting process.

[0003] In the Chinese utility model patent document with the patent number CN201821881690.6, entitled a grouting port plugging device, a technical solution is proposed, which pushes the rubber sleeve into the grouting hole by setting a positioning cylinder, a pushing sleeve and other structures, and then blocks and seals the grouting port through the deformation of the rubber sleeve. In the above technical solution, when sealing the grouting port, it is necessary to use multiple structures such as a positioning cylinder, a pushing sleeve, an extrusion sleeve, a rubber sleeve and multiple gaskets to cooperate with each other, which not only increases the cumbersomeness of the operation process, but also makes the sealing of the grouting port more time-consuming and laborious, and the rubber sleeve is mostly used once. After the grouting is completed, the rubber sleeve will remain in the grouting port and cannot be reused. To this end, we propose a blocking device for the grouting port for leak repair.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The utility model provides a technical solution: a blocking device for a leakage repair injection port, which is mainly used for the repair of leakage, cold penetration and the like of masonry buildings, and includes an expansion fixing sleeve 1, which is composed of a limiting portion 11 and an expansion portion 12. The expansion fixing sleeve 1 is made of rubber material, and the limiting portion 11 and the expansion portion 12 are made by integral injection molding. A plug hole 13 for inserting a perfusion needle 2 is provided in the middle of the expansion portion 12.

[0020] like Figure 1 and Figure 2 As shown in , the perfusion needle tube 2 includes a needle tube body 21, which is a hollow metal tube. The side wall of the needle tube body 21 is provided with a first external thread 22, and the top side wall of the needle tube body 21 is provided with a second external thread 23. After the needle tube body 21 is inserted into the insertion hole 13, by rotating the needle tube body 21, the first external thread 22 can interact with the expansion part 12 in the expansion fixing sleeve 1, and the expansion part 12 is deformed in the perfusion port, and the expansion part 12 is stretched and deformed outward at the same time, and the perfusion port is sealed. The perfusion needle tube 2 can be set with a smaller outer diameter, thereby reducing the aperture of the perfusion port opened on the repair surface, and achieving the effect of minimally invasive repair on the repair surface;

[0021] The second external thread 23 is used to be connected and fixed with the connecting port of the ball valve 3. The upper and lower ends of the ball valve 3 are respectively provided with quick connectors. The upper quick connector is used to connect with an external perfusion device, and the lower quick connector is used to connect with the top of the perfusion needle tube 2. The ball valve 3 is connected with the external perfusion device through the ball valve 3 to realize the perfusion operation of the waterproof filling material into the perfusion needle tube 2. The waterproof filling material used is mainly acrylate grouting material.

[0022] The ball valve 3 can be a straight-type ball valve or an L-type ball valve, which can be selected according to the specific construction requirements during the pouring construction process. At the same time, the ball valve 3 can also be set as a three-way valve. By connecting a pressure gauge in the third connection end, the pressure condition during the pouring process can be tested.

[0023] The side wall of the needle tube body 21 is integrally formed with a handle bar 24 symmetrically distributed on the left and right. The handle bar 24 facilitates the screwing operation of the needle tube body 21 and facilitates the needle tube body 21 to be screwed into the insertion hole 13 of the expansion part 12.

[0024] like Figure 2 and Figure 4As shown in the figure, the bottom of the expansion fixing sleeve 1 is located at the outer side wall of the expansion part 12 and is sleeved with a gasket 4. The gasket 4 is annular, and the inner diameter of the gasket 4 is adapted to the size of the expansion part 12 when it is not deformed. A card block 41 is integrally formed on the top of the gasket 4, and the card block 41 passes through the card slot 14. The card slot 14 is opened in the limiting part 11 of the expansion fixing sleeve 1, and the number of the card blocks 41 matches the number of the card slots 14. The number of the card blocks 41 is at least four, and the four card blocks 41 and the card slots 14 are evenly distributed in a circle around the axis of the expansion fixing sleeve 1. In the process of deforming the expansion part 12 by screwing in the perfusion needle tube 2, the limiting part 11 is limited by the card block 41, the card slot 14 and the gasket 4, thereby avoiding the problem that the limiting part 11 is completely brought into the perfusion port by the perfusion needle tube 2, resulting in the inconvenience of its subsequent disassembly.

[0025] The top of the clamping block 41 is provided with an arc-shaped inclined chamfer. By providing the inclined chamfer on the top of the clamping block 41, the insertion and connection between the clamping block 41 and the clamping slot 14 is facilitated.

[0026] The thickness of the gasket 4 is 0.5-1 mm. By providing a thinner gasket 4, the expansion fixing sleeve 1 can fit the injection port as closely as possible, thereby improving the sealing performance of the expansion fixing sleeve 1 to the injection port.

[0027] Working principle: During the use of this device, first, an injection port is opened at the location where leakage repair is required through external equipment such as a drilling rig. After the opening is completed, the expansion fixing sleeve 1 equipped with a gasket 4 is inserted into the injection port, and then the injection needle 2 is screwed from the socket 13 to the expansion part 12 through the handle rod 24. Under the action of the first external thread 22 on the side wall of the injection needle 2, the expansion part 12 is driven to deform in the injection port, thereby achieving the blocking and sealing of the injection port. Then, the top of the injection needle 2 is connected to the ball valve 3 and the external injection equipment, and acrylate slurry or other waterproof repair materials are injected into the injection needle 2 through the external injection equipment, so that it reaches the designated repair position through the injection port. After completing the injection operation, wait for a period of time. After the injection repair material has been roughly solidified, the device can be disassembled and then moved to the next injection port for reuse.
