[0002] Grouting in construction projects is a method of injecting certain solidifying slurries into cracks or pores in walls by appropriate methods, and improving their physical and mechanical properties through replacement, filling, extrusion, etc. Grouting for leak repair, also known as grouting, is a method of using a slurry as a leak repair material, and injecting the slurry into the gaps under pressure to make it diffuse and solidify, thereby achieving the main purpose of blocking water.

[0003] The existing grouting and plugging process generally uses an electric drill to drill holes in the cracks, then inserts grouting nails, and uses a pump to grout them. This method is suitable for large-scale leak repair. If this method is also used for multiple small-area leak repairs, it will be more troublesome, especially the pump is inconvenient to carry and transfer back and forth. Therefore, this application document proposes a small and portable self-pressure grouting and plugging device. Utility Model Content

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0035] Reference Figure 1-9 , a self-pressure grouting plugging device, comprising a container for discharging grouting material outwardly by compressed air;

[0036] The discharging end of the container is provided with a connecting piece, and the connecting piece in this embodiment has a self-closing and self-opening function;

[0037] The connecting piece is connected to the grouting nail through a pipeline.

[0038] In a specific embodiment of the utility model, the container is used to hold compressed air and grouting material. The grouting material is discharged from the discharge end into the pipeline under the action of compressed air, and then discharged from the grouting nail through the pipeline for grouting operation. It should be noted that when the container is in use, its discharge end should be facing downward so that the grouting material is accumulated at the discharge end, so as to ensure that the grouting material is discharged after the discharge end is opened. The pipeline and grouting nails in this solution adopt the existing conventional settings, and a ball valve can be set in the pipeline for manual control of the opening and closing of the grouting operation.

[0039] When performing grouting operations, first locate the cracks, then use an electric drill to drill holes. After drilling, insert the grouting nails, and then connect the grouting nails and the container with pipelines. When the container, pipeline and grouting nails are connected, compressed air can discharge the grouting material. During this process, the container can be lifted and grouting can be automatically performed, just like an IV bottle. During the grouting operation, multiple groups of this device can be set up at the same time to perform simultaneous grouting, thereby improving efficiency to a certain extent. Specific embodiment one:

[0041] A self-pressure grouting plugging device includes a container for discharging grouting material outwardly by compressed air;

[0042] A connector is provided at the discharge end of the container;

[0043] The connecting piece is connected to the grouting nail through a pipeline.

[0044] The container is: a first tank body 1 containing compressed air and grouting material. The first tank body 1 is used to contain compressed air and grouting material.

[0045] The connecting piece comprises a puncture connector 2, a quick connector and a tank connector 7. One end of the first tank body 1 is provided with the tank connector 7, and the outer end surface of the tank connector 7 is in a closed state.

[0046] A puncture column 6 is fixedly arranged on the inner upper part of the puncture connector 2. The puncture column 6 is an inner hollow cylinder, and a through hole is opened on its annular surface. The top of the puncture column 6 is conical. One end of the puncture connector 2 close to the puncture column 6 is threadedly connected to the outer end of the tank connector 7, and the puncture column 6 can pierce the outer end surface of the tank connector 7.

[0047] The quick connector includes a mother body 4 and a child body 3, one end of the mother body 4 and one end of the child body 3 are snap-connected, the other end of the mother body 4 is threadedly connected to one end of the puncture connector 2 away from the puncture column 6, and the other end of the child body 3 is connected through a pipeline and a grouting nail.

[0048] The quick connector in this scheme adopts existing equipment. The quick connector is a connector that can connect or disconnect the pipeline without tools. It is composed of a mother body and a daughter body. When not connected: when the ring of the mother body moves to the other end, the stainless steel ball automatically rolls outward, and the daughter body is disconnected due to the action of the valve spring force of the mother body and the daughter body. The valves of the daughter body and the mother body are closed separately, instantly blocking the flow of fluid; when connected: when the daughter body is inserted into the mother body, the ring returns to its original position under the action of the spring, and the steel ball rolls to lock the daughter body tightly. At the same time, the valves of the mother body and the daughter body push each other to open, and the fluid flows. The O-ring can completely block the leakage of the fluid.

[0049] The interior of the first tank body 1 near the connecting piece is conical, and a floating ball 5 is arranged inside the first tank body 1 .

[0050] Workflow: After the grouting nail is inserted into the hole, one end of the feed end pipeline of the grouting nail is connected, and the connection method adopts conventional connection, and then the other end of the pipeline is connected to the sub-body 3 (it should be noted that before the grouting starts, the sub-body 3 and the mother body 4 are disconnected), and the mother body 4 is threadedly connected to the puncture joint 2, and then the puncture joint 2 is threadedly connected to the tank joint 7 of the first tank body 1. In this process, the puncture column 6 on the puncture joint 2 can puncture the outer end surface of the tank joint 7 and enter into the tank joint 7. Due to the puncture A hole is provided on the column 6, so that the first tank body 1 and the puncture joint 2 can be connected. Since the puncture joint 2 is already connected to the mother body 4, although the puncture joint 2 is connected to the first tank body 1, the grouting material will not be discharged. After the above steps are completed, the first tank body 1 is hung to a suitable position so that its discharge end (i.e., the end where the connector is located) faces downward, and then the child body 3 is inserted into the mother body 4, so that the first tank body 1, the connector, the pipeline and the grouting nail are connected, and the grouting material is discharged from the grouting nail under pressure to perform the grouting operation;

[0051] During this period, the float 5 will always float on the upper surface of the grouting material. When the grouting material is emptied, the float 5 will fall to the conical position in the first tank body 1 under the action of gravity, thereby achieving a blocking effect to prevent the residual air after the grouting material is used up from entering the grouting position;

[0052] When the grouting operation is completed but the grouting material is not used up, the parent body 4 and the child body 3 can be directly disconnected. In this state, the parent body 4 can seal the first tank body 1, so that the first tank body 1 and the compressed air and grouting material inside it can still be retained for plugging leaks in other locations;

[0053] When the compressed air and grouting material in the first tank body 1 are used up, the connecting piece can be removed and cleaned for next use. Specific embodiment 2:

[0055] A self-pressure grouting plugging device includes a container for discharging grouting material outwardly by compressed air;

[0056] A connector is provided at the discharge end of the container;

[0057] The connecting piece is connected to the grouting nail through a pipeline.

[0058] The container is composed of a second tank body 9 containing compressed air and a gas tank 8 containing grouting material;

[0059] The second tank body 9 and the gas tank 8 are connected via a connecting piece.

[0060] The connecting piece comprises a puncture connector 2, a quick connector and a tank connector 7. The tank connector 7 is disposed at one end of the second tank body 9, and the outer end surface of the tank connector 7 is in a closed state.

[0061] A puncture column 6 is fixedly arranged on the inner upper part of the puncture connector 2. The puncture column 6 is an inner hollow cylinder, and a through hole is opened on its annular surface. The top of the puncture column 6 is conical. One end of the puncture connector 2 close to the puncture column 6 is threadedly connected to the outer end of the tank connector 7, and the puncture column 6 can pierce the outer end surface of the tank connector 7.

[0062] The interior of the second tank body 9 near the connecting piece is conical, and a float 5 is arranged inside the second tank body 9 .

[0063] The connecting piece includes a quick connector and two puncture connectors 2. A tank connector 7 is provided at the outlet end of the gas cylinder 8, and a tank connector 7 is also provided at the end of the second tank body 9 away from the connecting piece. The two puncture connectors 2 are respectively connected to the tank connector 7 on the gas cylinder 8 and the tank connector 7 on the second tank body 9 away from the connecting piece, and the two ends of the quick connector are respectively connected to the two puncture connectors 2.

[0064] The difference between the second embodiment and the first embodiment is the choice of container. In the first embodiment, only a first tank body 1 is required, while in the second embodiment, it is composed of a second tank body 9 and a gas tank 8;

[0065] The puncture connector 2, quick connector and float 5 in the second embodiment are the same as those in the first embodiment, and the usage is also the same, so they will not be described in detail here.

[0066] When in use, the second tank body 9 is connected to the grouting nail, and the compressed gas enters the second tank body 9 from the gas tank 8 through the connecting piece, so that the grouting material enters the pipeline from the second tank body 9 through the connecting piece, and then enters the grouting nail, and then is discharged from the grouting nail to stop the leak. Its working principle is the same as that of Example 1.

[0067] Workflow: The connection between the second tank body 9, the connecting piece and the grouting nail refers to the workflow of the first embodiment;

[0068] When connecting the second tank body 9 and the gas tank 8, firstly, the sub-body 3 and the main body 4 in the connecting piece are respectively connected to the two puncture joints 2 in the connecting piece, then one of the puncture joints 2 is connected to the tank joint 7 of the gas tank 8, and then the other puncture joint 2 is connected to the tank joint 7 on the second tank body 9 away from the connecting piece, and finally the sub-body 3 and the main body 4 in the connecting piece are connected, so that the connection between the second tank body 9 and the gas tank 8 is completed;

[0069] The compressed air in the gas tank 8 enters the second tank body 9 through the connecting piece, and then grouting is carried out. After the grouting is completed, the connecting piece and the connecting piece are removed for cleaning and used for the next time. If the compressed air and grouting material are not used up this time, the connection between the second tank body 9 and the pipeline can be disconnected separately, or the second tank body 9 and the gas tank 8 can be disconnected together, and the characteristics of the quick connector can be used to achieve the closure of the second tank body 9 and the gas tank 8.

[0070] In the second embodiment, the gas tank 8 may be replaced with an air pump, and the air pump may be used to inject air into the second tank body 9 to achieve the effect of discharging the grouting material.
