Description

Technical Field

[0001] This utility model belongs to the field of aqueduct technology, and specifically relates to a U-shaped aqueduct deformation joint connection structure. Background Technology

[0002] China has a long history of building aqueducts. In ancient times, people carved wooden channels to divert water across river valleys and depressions to solve the problem of water scarcity in some areas. With economic development and social progress, many water conservancy projects and water diversion projects still make extensive use of aqueducts, and many new and modern aqueducts with distinctive features have been created.

[0003] U-shaped aqueducts are currently the most widely used type of aqueduct, and the expansion joint is a crucial point in aqueduct construction. The commonly used water-stopping method for U-shaped aqueducts is a pressure plate type water-stop structure. This involves pre-embedding or implanting bolts on both sides of the expansion joint, and tightening the nuts to compress the flat steel, thus fixing the rubber waterstop at the joint. However, it is difficult to ensure the waterstop is fixed evenly during construction; unevenness leads to leakage. Furthermore, it has two insurmountable drawbacks: first, the material ages over time, making the expansion joint prone to leakage, especially in regions with extreme cold, large temperature differences, and strong ultraviolet radiation; second, the bolts are prone to corrosion, making repairs complicated and significantly hindering waterstop replacement. Utility Model Content

[0004] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing a U-shaped aqueduct expansion joint connection structure, thereby improving the waterproofness, durability, and convenience of the expansion joint connection structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A U-shaped aqueduct expansion joint connection structure includes a water-stop bar and an arc bolt. The water-stop bar is set between the end faces of two U-shaped aqueducts. The two ends of the arc bolt pass through the end faces of the two U-shaped aqueducts respectively and extend to the inner sides of the two U-shaped aqueducts. The arc bolt is fastened with a nut. Both ends of the arc bolt are provided with a sealing element.

[0007] To better realize this utility model, the above structure is further optimized. Two water-stop bars are set between the end faces of the two U-shaped troughs, and an arc bolt is inserted between the two water-stop bars.

[0008] To better realize this utility model, the above structure is further optimized by providing multiple arc-shaped bolts.

[0009] To better realize this utility model, the above structure is further optimized by providing an asphalt layer and a first acrylic emulsion mortar layer above the waterstop bar.

[0010] To better realize this utility model, the above structure is further optimized by providing a polyethylene foam board below the water-stop bar.

[0011] To better realize this utility model, the above structure has been further optimized, and both the arc bolt and the nut are made of stainless steel.

[0012] To better realize this utility model, the above structure is further optimized. The inner side of the U-shaped aqueduct is provided with a countersunk hole, and the end of the arc bolt extends into the countersunk hole.

[0013] To better realize this utility model, the above structure is further optimized, and the sealing element is a cover covering the end of the arc bolt.

[0014] To better realize this utility model, the above structure is further optimized by providing a second acrylic emulsion mortar layer on the outer side of the cover.

[0015] To better realize this utility model, the above structure is further optimized so that the second acrylic emulsion mortar layer is at the same height as the inner side of the U-shaped aqueduct.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] The U-shaped aqueduct expansion joint connection structure provided by this utility model places a water-stop rod in the expansion joint between two U-shaped aqueducts and uses arc bolts to connect and fasten the two U-shaped aqueducts together, causing the water-stop rod in the expansion joint to be squeezed and deformed, filling the internal gap. Even if the aqueduct settles, the water-stop rod will rotate with it, and the waterproof function will not be affected. It has good waterproof performance, durability and convenience.

[0029] Please refer to Figures 1-5This application provides a U-shaped aqueduct expansion joint connection structure, including a water-stop rod 1 and an arc bolt 2. The water-stop rod 1 is disposed between the end faces of two U-shaped aqueducts 3, and the two ends of the arc bolt 2 pass through the end faces of the two U-shaped aqueducts 3 respectively and extend to the inner surfaces of the two U-shaped aqueducts 3, as shown below. Figure 2 As shown, in this embodiment, a countersunk hole 301 is provided on the inner side of the U-shaped aqueduct 3. The end of the arc bolt 2 extends into the countersunk hole 301. The countersunk hole design can better seal and protect the end of the arc bolt 2. The arc bolt 2 and the nut 201 are fastened together. A sealing rubber gasket and a washer are also provided below the nut 201. The nut 201 is fixed firmly with a wrench, and the sealing rubber gasket and washer below are pressed tightly. Both the arc bolt 2 and the nut 201 are made of stainless steel, which has excellent rust and corrosion resistance. Both ends of the arc bolt 2 are provided with sealing elements. In this embodiment, the sealing element is a plastic cap 7 covering the end of the arc bolt 2. The cap 7 can effectively prevent external water flow and impurities from invading and corroding the arc bolt 2. Moreover, a second acrylic emulsion mortar layer 8 is provided on the outside of the cap 7, which plays a secondary sealing and protection role. The second acrylic emulsion mortar layer 8 is at the same height as the inner side of the U-shaped aqueduct 3, so that the acrylic emulsion mortar fills the entire countersunk hole 301.

[0030] like Figure 4 As shown, in this embodiment, two water-stop rods 1 are set up vertically between the end faces of the two U-shaped troughs 3. The two water-stop rods 1 play a double protection role. The bottom water-stop rod 1 serves as the last waterproof wall. Multiple arc bolts 2 are set up. All arc bolts 2 are inserted between the two water-stop rods 1, which can effectively protect the arc bolts 2 from water erosion and improve their service life.

[0031] Above the top waterstop 1, an asphalt layer 4 and a first acrylic emulsion mortar layer 5 are installed. These layers not only provide sealing and waterproofing but also strengthen the connection between expansion joints. The first acrylic emulsion mortar layer 5, positioned above the asphalt layer 4, protects the lower asphalt layer 4 and waterstop 1 from external climatic conditions such as strong ultraviolet radiation, significantly improving the durability of the compression-sealed waterstop 1 and asphalt layer 4. Below the bottom waterstop 1, a polyethylene foam board 6 is installed.

[0032] In use, the arc bolt 2 passes through the countersunk hole 301 through the pre-drilled hole on the U-shaped aqueduct 3 to connect the two U-shaped aqueducts 3. Then, the nut 201 is tightened with a wrench to bring the end faces of the two U-shaped aqueducts 3 closer together, squeezing the water-stop bar 1 in the middle to achieve the purpose of waterproofing. Next, the cover 7 is placed over the end of the arc bolt 2, and acrylic emulsion mortar is filled into the countersunk hole 301. Asphalt and acrylic emulsion mortar are filled in sequence above the water-stop bar 1 so that the acrylic emulsion mortar is flush with the inside of the U-shaped aqueduct 3. Finally, a waterproof and seepage-proof layer 9 is applied to the entire inside of the U-shaped aqueduct 3.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
