Description

Technical Field

[0001] The utility model belongs to the technical field of grouting and leak-proofing, in particular to a grouting and leak-proofing structure. Background Art

[0002] Currently, my country is experiencing an increasing number of high-rise buildings, and the development and utilization of underground space has become a trend. However, basement leakage is very common, which not only affects the normal use of buildings, but also has a great impact on their functionality, structural safety and durability.

[0003] There are many reasons for basement leakage. Design factors include uneven structural settlement, unclear waterproofing design methods, insufficient understanding of self-waterproofing, and insufficient understanding of waterproofing materials. Construction factors include poor management, lax construction process control, improper treatment of special areas, and non-compliant waterproofing materials. Serious basement leakage requires repair work.

[0004] Technical solution of existing technology: Generally, traditional leak plugging adopts chemical grouting process. According to the thickness of concrete, a hole is drilled to 1 / 3 of the concrete, and then a grouting needle is installed. The leak plugging slurry is injected into the concrete cracks with a high-pressure grouting machine to achieve the purpose of water stopping.

[0005] Disadvantages of existing technology:

[0006] 1. As cracks appear in the concrete, the local strength decreases. If holes are drilled and grouting is injected into the cracks, the cracks in the concrete will be aggravated, causing greater damage to the structure.

[0007] 2. The effect of local grouting is limited and can only stop water in a certain area. It is easy to cause leakage in the surrounding weak areas, making the maintenance work repeated and the effect poor. Utility Model Content

[0008] In view of this, the present invention aims to provide a grouting plugging structure to solve at least one technical problem in the background technology.

[0009] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0010] A grouting and plugging structure includes a grouting needle and a support frame device. Several grouting needles are evenly and equidistantly inserted into the wall to be plugged. The bottom of the support frame device is set on the wall to be plugged, and several grouting needles can pass through the support frame device; the ends of the grouting needles pass through the outer skin of the wall to be plugged and are connected to the outer waterproof layer of the wall to be plugged.

[0011] The grouting needle is threadedly connected to the waterproof and leak-proof high-pressure grouting machine for grouting.

[0012] The support frame device includes a base, a telescopic rod assembly, and a card plate. One end of the telescopic rod assembly is arranged on the base, and the other end of the telescopic rod assembly is connected to the card plate. The card plate is provided with a plurality of through holes that can allow the grouting needle to pass through.

[0013] Furthermore, the telescopic rod assembly includes an inner telescopic tube, an outer telescopic tube, and a locking bolt. One end of the outer telescopic rod is set on the base, and the other end is slidably set on the outside of the inner telescopic tube. A locking bolt is provided on the outer wall of the outer telescopic tube, and the outer telescopic tube is abutted against the inner telescopic tube through the locking bolt.

[0014] In the present application, the telescopic rod assembly can be adjusted according to the length of the grouting needle and can adapt to different grouting needles.

[0015] Furthermore, the length of the grouting needle is greater than the thickness of the outer skin of the wall to be sealed.

[0016] Furthermore, the base is cross-shaped.

[0017] Furthermore, the number of the telescopic rod assemblies is 4, and the telescopic rod assemblies are arranged at the ends of the cross-shaped base.

[0018] Furthermore, the position of the locking bolt corresponds to the position of the end portion of the base.

[0019] Furthermore, the number of through holes is 4, and the diameter of the through holes is corresponding to the diameter of the grouting needle.

[0020] Furthermore, the card board is square, the through holes are arranged around the card board, the distance between the centers of the through holes is 500 mm, and the through holes are parallel or perpendicular to the card board.

[0021] Furthermore, the distance between the centers of the plurality of grouting needles is 500 mm.

[0022] Compared with the prior art, the grouting plugging structure described in the present invention has the following advantages:

[0023] 1. This application uses a drill bit selected according to the thickness of the concrete structure to penetrate the concrete structure. Grouting needles are installed in a grid pattern with a spacing of 500mm. Grouting liquid is injected directly into the outer waterproof layer. The grouting liquid reacts chemically with water, repairing the waterproof layer from the water-facing side, thereby improving the success rate of basement grouting repairs. Internal cracks in the concrete are sealed. After water stopping is complete, the needle is removed and the pinhole is sealed with a leak-proof sealant. This has a good sealing effect and seals from the inside.

[0024] 2. This application supports the grouting needle through the support frame device. The grouting needle is installed through the support frame device. The card plate is rectangular and has 4 through holes on it. The distance between the centers of the drill bits on all sides is 500mm. The grouting and plugging effect is good. When grouting the grouting holes one by one, the card plate can position the grouting needle and play a certain role. BRIEF DESCRIPTION OF THE DRAWINGS
