Description

Technical Field

[0001] This utility model belongs to the field of anchor cable construction technology, and relates to grout stopping in anchor cable construction, especially a reusable anchor cable grout stopping device. Background Technology

[0002] During the construction of pressure-dispersive anchor cable support, grouting is required. In order to limit the grouting range and prevent the grout from spreading along the free end of the anchor cable, the grout stop bag is an essential component. Its main function is to seal the anchoring section of the anchor cable during grouting, ensure the anchoring effect, and save grouting materials.

[0003] Traditionally, grout-stopping bags are placed on the outside of the anchor cable, with both ends of the bag fixed to the anchor cable with tape. This fixing method leaves the grout-stopping bag on the anchor cable after grouting, making it impossible to remove, recycle, or reuse. This not only increases construction costs but also wastes resources.

[0004] To address this issue, we propose a reusable anchor cable grout-stopping device. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a simple, reusable anchor cable grouting device.

[0006] To solve the above problems, the technical solution of this utility model is as follows:

[0007] A reusable anchor cable grouting device, wherein the anchor cable is inserted into the anchor cable hole, comprising:

[0008] The grout-stopping membrane is fitted onto the outside of the anchor cable and closely adheres to the inner wall of the anchor cable hole, making it suitable for grout-stopping purposes;

[0009] The locking component is tightly clamped onto the grout-stopping membrane, dividing the grout-stopping membrane into a grout-stopping section and a grouting section, which is suitable for grout-stopping.

[0010] Several sealing components are inserted into the grout-stopping section of the grout-stopping membrane and surround the outside of the anchor cable;

[0011] When several sealing components are inflated, the grout-stopping membrane adheres tightly to the anchor cable holes;

[0012] When venting from several closures, it is suitable to remove several closures.

[0013] In a further embodiment, the locking assembly includes a hose clamp, a waterstop strip, and a pad, with an anchor cable inserted inside the pad, a waterstop strip wrapped around the side of the pad, and the hose clamp tightly fastened to the outside of the waterstop strip.

[0014] The grout-stopping membrane is sandwiched between the waterstop strip and the hose clamp.

[0015] In a further embodiment, the closure is an inflatable core mold.

[0016] In a further embodiment, the waterstop strip is a rubber waterstop strip that swells when exposed to water.

[0017] In a further embodiment, the anti-slurry membrane is made of plastic.

[0018] In a further embodiment, the pad is made of an elastic material or a water-swellable material.

[0019] In a further embodiment, the anchor cable includes several steel strands, several grouting pipes, and an venting pipe.

[0020] In a further embodiment, the length of the grout-stopping section is 1 meter, and the length of the grouting section is 10 centimeters.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This grout-stopping device consists of a grout-stopping membrane fitted onto the anchor cable. One side of the grout-stopping membrane is secured with a locking assembly, which divides the grout-stopping membrane into a grout-stopping section and a grouting section. Several sealing elements are also installed inside the grout-stopping section, and these sealing elements can be inflated. When the sealing elements are inflated, they support the grout-stopping membrane and press it tightly against the inner wall of the anchor cable hole, which is suitable for grout-stopping. When the sealing elements are deflated, several sealing elements can be pulled out, making recycling convenient and quick. They can also be reused in the next construction, reducing material costs.

[0023] 2. The locking device of this grout-stopping device includes a hose clamp, a waterstop strip, and a pad. Anchor cables are inserted into the pad, and the waterstop strip is wrapped around the outside of the pad. The hose clamp is tightly fastened to the outside of the waterstop strip, and the grout-stopping membrane is sandwiched between the waterstop strip and the hose clamp. The three parts fit together tightly to form a reliable anti-leakage structure, effectively preventing grout from seeping into the sealing component. Furthermore, after the sealing component is inflated, the grout-stopping membrane adheres tightly to the anchor cable hole wall, further enhancing the grout-stopping effect and ensuring construction quality.

[0024] 3. This grout-stopping device eliminates the cumbersome process of binding grout-stopping bags and grouting in the original design. It only requires inflating the sealing parts before grouting, which greatly simplifies the construction steps, reduces construction time and manpower input, and significantly improves construction efficiency.

[0030] Example 1:

[0031] A reusable anchor cable grout-stopping device, wherein an anchor cable 4 is inserted into the anchor cable hole, such as... Figures 1 to 3 As shown, the anchor cable 4 is fitted with several sealing components 1, a grout-stopping membrane 2, and a locking assembly 3. The grout-stopping membrane 2 is cylindrical and fitted with a locking assembly 3 on one side. The locking assembly 3 divides the grout-stopping membrane 2 into a grout-stopping section and a grouting section. Several sealing components 1 are inserted into the grout-stopping section and surround the outside of the anchor cable 4. Preferably, the length of the grout-stopping section of the grout-stopping membrane 2 is 1 meter, and the length of the grouting section of the grout-stopping membrane 2 is 10 centimeters. The sealing component 1 is an inflatable core mold. The grout-stopping membrane 2 is a long strip of PE flat bag. The diameter of the grout-stopping membrane 2 is 3 centimeters larger than the diameter of the anchor cable hole to ensure effective grout stopping. Cotton can also be wrapped around both ends of the grout-stopping membrane 2 to improve the grout stopping effect.

[0032] Anchor cable 4 includes several steel strands, several grouting pipes, and an exhaust pipe, suitable for several grouting operations, used to fix the steel strands. Locking assembly 3 includes hose clamp 31, waterstop strip 32, and pad 33. The pad 33 has several round holes spaced apart for inserting several steel strands, several grouting pipes, and an exhaust pipe. The waterstop strip 32 is wrapped around the outer surface of the pad 33. Both the pad 33 and the waterstop strip 32 are located inside the grout-stopping membrane 2. The hose clamp 31 is tightly clamped on the outer surface of the waterstop strip 32, so that the grout-stopping membrane 2 is clamped between the hose clamp 31 and the waterstop strip 32. Preferably, the pad 33 is made of elastic material or water-swellable material; the waterstop strip 32 is a rubber water-swellable waterstop strip; the hose clamp 31 is made of steel. Before inserting the anchor cable 4 and the grout-stopping membrane 2 into the anchor cable hole, a small amount of water is sprinkled on the waterstop strip 32 to ensure the sealing effect of the locking assembly 3 and prevent grout from flowing into the grout-stopping section of the grout-stopping membrane 2.

[0033] The working principle of this utility model is as follows: Anchor cable 4 is inserted into pad block 33, waterstop strip 32 is wrapped around pad block 33, and several sealing parts 1 are installed on the outside of anchor cable 4. Grout-stopping membrane 2 is fitted on the outside of anchor cable 4 and several sealing parts 1, and hose clamp 31 is attached to grout-stopping membrane 2. After installation, anchor cable 4, grout-stopping membrane 2, and several sealing parts 1 are inserted into anchor cable hole. The sealing parts 1 are inflated so that the sealing parts 1 support the grout-stopping membrane 2 to be tightly attached to the inner wall of anchor cable hole, and grouting can then be performed. After grouting is completed, wait for the grout to initially solidify, and then release the gas inside the several sealing parts 1 to facilitate the extraction of the sealing parts 1. The sealing parts 1 can be reused in the next construction, saving material costs.
