Description

Technical Field

[0001] The utility model belongs to the technical field of grouting, etc., and particularly relates to an underwater grouting device. Background Art

[0002] At present, when repairing underwater concrete under deep water conditions, anchor bars need to be implanted, and in order to increase the anchoring degree between the anchor bars and the concrete, anchoring agents need to be poured in. Among them, the construction of plane anchoring agents basically adopts the direct pouring method, and for vertical structures with deeper holes, the injection gun is currently mainly used to inject the anchoring agent into the anchor hole or the drug roll anchoring agent is directly placed in the anchor hole. These two methods have the following disadvantages:

[0003] The injection gun method is that the diver uses an injection gun to inject the anchoring agent in the tube into the anchor hole. Due to the high viscosity of the anchoring glue, pipe blockage is prone to occur. In addition, the tubular anchoring agent is directly processed by the manufacturer and is a disposable product with high cost. In addition, the anchoring agent has a certain fluidity and is easy to flow out when entering the anchor hole. It cannot be adjusted in real time on site and has low flexibility.

[0004] The drug roll type is that the anchor agent is processed into the form of a drug roll. The diver puts the drug roll into the anchor hole underwater, and then the diver inserts the anchor bar directly into the anchor hole with the anchor agent drug roll. The diver punctures the drug roll while rotating the anchor bar to make it firmly bonded to the anchor hole. However, the drug roll skin material is generally plastic, and if it is left in the anchor hole, there is a risk of reducing the bonding strength of the anchor agent. Utility Model Content

[0028] The utility model embodiment provides an underwater grouting device, referring to Figure 1-4 As shown, the device at least includes an inflatable component 1, a sealed cabin 2, a grouting pipe 3 and a grouting pipe 4. The sealed cabin 2 is hollow inside and is used to place the anchoring agent. One end of the sealed cabin 2 is connected to the inflatable component 1; one end of the grouting pipe 3 is connected to the other end of the sealed cabin 2, and the other end of the grouting pipe 3 is inserted into the bottom of the anchor hole A; one end of the grouting pipe 4 is inserted into the inside of the anchor hole A, and the other end of the grouting pipe 4 is installed outside the anchor hole A. The underwater grouting device provided by the utility model improves the efficiency and accuracy of underwater anchoring construction, ensuring that the anchoring agent can be accurately injected into the bottom of the anchor hole A. Among them, the design of the sealed cabin 2 not only ensures the airtightness of the anchoring agent during the grouting process, avoiding leakage and contamination of the anchoring agent, but also can adapt to the environment of large water depth and withstand the water pressure under large water depth. The pressure generated by the inflation component 1 injects the anchoring agent into the underwater anchor hole A through the grouting pipe 3. The inflation component 1 inflates the sealed cabin 2 through the inflation pipe 101, and the pressure generated pushes the anchoring agent into the anchor hole A through the grouting pipe 3. The anchoring agent flows in the anchor hole A and fills the entire hole. Through the setting of the grouting pipe 4, on the one hand, the excess air and water in the anchor hole A can be effectively discharged, the filling effect and anchoring strength of the anchoring agent can be improved, and the anchoring agent can be evenly distributed in the hole to form a stable anchoring effect. On the other hand, the other end of the grouting pipe 4 is installed outside the anchor hole A, and it can be observed in real time whether the anchor hole A is full of anchoring agent.

[0029] In some embodiments, the length and diameter of the grouting pipe 3 and the grouting pipe 4 can be adjusted according to the depth and width of the anchor hole A to adapt to anchor holes A of different sizes. The inflation method of the inflatable component 1 can be manual inflation or electric inflation, and the appropriate inflation device can be selected according to the site conditions.

[0030] In some embodiments, the grouting pipe 3 can be in the form of a 90° bend pipe or a straight grouting pipe 3, wherein the 90° bend pipe can be used to grout the side anchor holes A, and the straight grouting pipe 3 can be used to grout the bottom anchor holes A.

[0031] Furthermore, the underwater grouting device also includes a plugging member 5, the size of which is the same as the opening size of the anchor hole A. The plugging member 5 is used to seal the opening of the anchor hole A to prevent leakage of the anchoring agent during the grouting process. The plugging member 5 is tightly matched with the opening of the anchor hole A, and the grouting pipe 3 and the grouting pipe 4 are smoothly inserted into the anchor hole A through the through hole thereon, and the pressure in the anchor hole A is ensured to be uniform.

[0032] In some embodiments, the material of the plugging member 5 can be rubber, plastic or metal, and the appropriate material can be selected according to different use environments. The shape and size of the plugging member 5 can be customized according to the specific size of the anchor hole A to ensure the sealing effect.

[0033] Furthermore, the plugging member 5 is provided with three through holes, and the three through holes are respectively inserted into the grouting pipe 3, the grouting pipe 4 and the anchor bar B. By providing three through holes, the plugging member 5 can effectively fix the grouting pipe 3, the grouting pipe 4 and the anchor bar B, ensuring the stability and reliability of the grouting process.

[0034] In some embodiments, the sizes of the three through holes match the sizes of the grouting pipe 3 , the grouting pipe 4 and the anchor bar B, respectively, which can effectively ensure that the anchoring agent does not overflow.

[0035] In some embodiments, the number and position of the through holes can be adjusted according to specific construction requirements to adapt to different layouts of anchor holes A. The size of the through holes on the plugging member 5 can be adjusted according to the size of the grouting pipe 3, the grouting pipe 4 and the anchor bar B to ensure that each component can be smoothly inserted.

[0036] Furthermore, the inflation assembly 1 includes an inflation tube 101 and a gate valve 102, one end of the inflation tube 101 is arranged outside the sealed cabin 2, and the other end of the inflation tube 101 is arranged inside the sealed cabin 2; the gate valve 102 is arranged on the inflation tube 101 and is located outside the sealed cabin 2. The design of the inflation tube 101 and the gate valve 102 makes the pressure control during the grouting process more precise and improves the grouting effect; wherein, the inflation tube 101 is used to inject air or gas into the sealed cabin 2 to generate pressure to push the anchor. The gate valve 102 is used to control the gas flow of the inflation tube 101 to ensure that the grouting operation is performed under appropriate pressure. By adjusting the gate valve 102, the pressure in the sealed cabin 2 can be accurately controlled to ensure the stable injection of the anchor. The gate valve 102 can also effectively control the amount of anchor filling, and control the filling and stopping of the anchor at any time, which can greatly reduce the loss of the anchor, thereby reducing costs. At the same time, the provision of the gate valve 102 facilitates the operator's control over the inflation process, thereby enhancing the controllability and safety of the grouting process.

[0037] In some embodiments, one end of the inflation tube 101 is connected to an air compressor, and the air compressor is used to pressurize the sealed cabin 2 to achieve filling of the anchoring agent. The type of the gate valve 102 can be a manual valve or an electric valve according to specific needs to improve the convenience and accuracy of operation.

[0040] Furthermore, the sealed cabin 2 further includes four support plates 206, which are respectively arranged on the inner sides of the tops of the four side plates 203. The support plates 206 are tightly connected with the side plates 203 and the cover plate 204 to form a solid overall structure, thereby improving the stability of the sealed cabin 2; the design of the support plates 206 enhances the structural strength of the sealed cabin 2, ensuring that it remains stable under high pressure conditions; by adding the support plates 206, the durability and service life of the sealed cabin 2 are improved. By arranging the support plates 206 in the sealed cabin 2, the water pressure at a great depth can be better withstood.

[0041] In some embodiments, the number and position of the support plates 206 can be adjusted according to the specific design of the sealed cabin 2 to achieve the best support effect while also ensuring the structural safety of the sealed cabin 2 .

[0042] Furthermore, the cover plate 204 is connected to the four support plates 206 by bolts 207.

[0044] Furthermore, the bottom plate 201, the side plate 203, the cover plate 204 and the support plate 206 are all made of steel plates, and the thickness of the steel plates is t≥25 mm. The use of steel plates with a thickness of t≥25 mm as the material of the bottom plate 201, the side plate 203, the cover plate 204 and the support plate 206 can provide sufficient strength and rigidity to ensure that the sealed cabin 2 does not deform under deep water conditions. At the same time, the steel plate has good corrosion resistance and durability, is suitable for underwater environments, and prolongs the service life of the device.

[0045] In some embodiments, the thickness of the steel plate can be adjusted according to specific needs to balance the requirements of strength and weight.
