Abstract
Description
Technical Field
[0001] This utility model relates to the field of cofferdam technology, specifically a device for rapidly constructing pile membrane cofferdams. Background Technology
[0002] A cofferdam is a temporary water-retaining structure built on the foundation of a river, lake, or body of water. Its core function is to isolate the construction area from the water body, creating a dry working environment. By preventing water and sediment from entering the foundation pit, cofferdams provide safety guarantees for the construction of hydraulic engineering projects (such as dams and locks) and bridge foundations.
[0003] Regarding the above and existing related technologies: When constructing cofferdams, traditional cofferdam devices are time-consuming and labor-intensive to build. In order to achieve rapid construction, pile-membrane cofferdams are used to shorten the construction period. However, when using geomembrane to surround the piles, the geomembrane is easily damaged when the piles or geomembrane are under stress due to the lack of a protective mechanism between the geomembrane and the piles. Therefore, a pile-membrane cofferdam device suitable for rapid construction is proposed to address the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This utility model provides a device for quickly constructing a pile-membrane cofferdam, comprising three piles, a geomembrane, and multiple protective devices. The geomembrane is located on one side of the three piles. The multiple protective devices are respectively located on the surface of the three piles. Each protective device includes a protective cylinder, which is sleeved on the surface of the pile. Multiple positioning pins are threaded onto the inner surface of the protective cylinder. The protective cylinder is located on one side of the geomembrane, and a fixing pin is threaded onto the inner wall of the protective cylinder. Two support blocks are sleeved on the surface of the fixing pin. Limiting rings are fixedly connected to both the upper and lower ends of the protective cylinder. The two limiting rings are located at the upper and lower ends of the geomembrane, respectively. By rotating the positioning pins to the inner wall of the protective cylinder, the protective cylinder and positioning pins can protect the piles and geomembrane, reducing wear between them.
[0006] Preferably, the inner walls of the two support blocks are rotatably connected to a rotating plate, and the inner wall of the rotating plate is slidably connected to a sliding plate. Pushing the sliding plate allows it to slide on the inner wall of the rotating plate, with the sliding plate resting on the soil layer. By setting the rotating plate and the sliding plate, the protective cylinder and the pile can be supported.
[0007] Preferably, both sides of the skateboard are rotatably connected to rotating posts, and the inner wall of the rotating posts is fitted with insert rods. The insert rods are inserted into the inner wall of the rotating posts and into the soil layer. By setting the rotating posts and insert rods, the position of the skateboard can be restricted.
[0008] Preferably, the inner walls of the rotating plate and the sliding plate are threaded with limit pins. When the sliding plate slides to a suitable position, the limit pins are rotated to the inner walls of the rotating plate and the sliding plate, and the limit pins can restrict the position of the sliding plate within the rotating plate.
[0009] Preferably, the surface of the slide plate is provided with multiple limiting holes, and the surface of the limiting pin is threadedly connected to the inner wall of the limiting hole of the slide plate. When the limiting pin rotates, the limiting pin rotates to the inner wall of the limiting hole of the slide plate, and the opening of the limiting hole can accommodate the limiting pin.
[0010] Preferably, the surface of the geomembrane is provided with a prompting device, which includes a clamping plate that is fitted onto the surface of the geomembrane. A storage plate is fixedly connected to the bottom end of the clamping plate. A limiting block is inserted into the inner surface of the storage plate, and a prompting strip is provided on the inner surface of the storage plate. Pushing the clamping plate allows it to fit onto the surface of the geomembrane. By setting the clamping plate, storage plate, and limiting block, the position of the geomembrane can be indicated to personnel.
[0011] Preferably, the inner wall of the clamping plate is threaded with a threaded post, and the side wall of the threaded post is rotatably connected with a clamping plate. The clamping plate is located on one side of the geomembrane. The threaded post drives the clamping plate to move, and the clamping plate will clamp onto the surface of the geomembrane. By setting the threaded post and the clamping plate, the position of the clamping plate can be restricted.
[0012] The advantages of this utility model are:
[0013] 1. When using the pile rod, this utility model involves prying open the protective sleeve and then pushing it to fit over the pile rod surface. The positioning pin is then rotated to the inner wall of the protective sleeve. Two support blocks are then positioned appropriately on the surface of the protective sleeve. A fixing pin is inserted into the inner walls of the two support blocks and the inner wall of the protective sleeve. The rotating plate is then pushed to rotate within the support blocks. Once the rotating plate reaches a suitable angle, the sliding plate is pulled to slide within the rotating plate. After the sliding plate reaches a suitable position, the limiting pin is rotated to the inner wall of the rotating plate and the limiting hole of the sliding plate. The rotating column is then rotated to adjust the orientation of the hole. The insertion rod is then inserted into the inner wall of the rotating column and into the soil. This entire device protects the geomembrane, reduces wear on the pile rod surface, and also assists in supporting the protective sleeve and the pile rod, reducing the risk of the protective sleeve moving erratically.
[0014] 2. After the geomembrane is installed, the reflective strip is inserted into the inner surface of the storage plate. Then, the limiting block is pushed to insert into the inner surface of the storage plate. Next, the clamping plate is placed on the surface of the geomembrane. After the clamping plate is placed, the threaded column is rotated to rotate on the inner wall of the clamping plate. The threaded column drives the clamping plate to move. The clamping plate squeezes the geomembrane against the side wall of the storage plate. By setting up the entire device, the position of the geomembrane can be indicated to personnel, thereby reducing the situation of accidental contact with the geomembrane at night.

[0023] Please see Figure 1-5As shown, a pile-membrane cofferdam device suitable for rapid construction includes three piles 1, a geomembrane 2, and multiple protective devices 3. The geomembrane 2 is located on one side of the three piles 1. The multiple protective devices 3 are respectively located on the surface of the three piles 1. Each protective device 3 includes a protective cylinder 31, which is fitted onto the surface of the pile 1. Multiple positioning pins 32 are threaded onto the inner surface of the protective cylinder 31. The protective cylinder 31 is located on one side of the geomembrane 2, and a fixing pin 34 is threaded onto the inner wall of the protective cylinder 31. Two support blocks 33 are fitted onto the surface of the fixing pin 34. Limiting rings are fixedly connected to both the upper and lower ends of the protective cylinder 31, and the two limiting rings are respectively located at the upper and lower ends of the geomembrane 2. During operation, the protective cylinder 31 is opened and then pushed, so that the protective cylinder 31 fits onto the surface of the pile 1. Then, the positioning pins 32 are rotated to the inner wall of the protective cylinder 31. By setting the protective cylinder 31 and the positioning pins 32, the piles 1 and the geomembrane 2 can be protected, reducing wear between the geomembrane 2 and the piles 1.
[0024] The inner walls of the two support blocks 33 are rotatably connected to a rotating plate 35, and the inner wall of the rotating plate 35 is slidably connected to a sliding plate 36. During operation, the rotating plate 35 is pushed to rotate on the inner wall of the support block 33. After the rotating plate 35 rotates to a suitable angle, the sliding plate 36 is pushed to slide on the inner wall of the rotating plate 35. The sliding plate 36 rests on the soil layer. By setting the rotating plate 35 and the sliding plate 36, the protective cylinder 31 and the pile rod 1 can be supported.
[0025] Both sides of the slide plate 36 are rotatably connected to rotating posts 37, and insert rods 38 are inserted into the inner wall of the rotating posts 37. During operation, the slide plate 36 drives the rotating posts 37 to move. During the movement of the rotating posts 37, the rotating posts 37 are rotated so that the holes of the rotating posts 37 are perpendicular to the soil layer. Then, the insert rods 38 are inserted into the inner wall of the rotating posts 37 and the soil layer. By setting the rotating posts 37 and the insert rods 38, the position of the slide plate 36 can be restricted.
[0026] The inner walls of the rotating plate 35 and the sliding plate 36 are threadedly connected with a limiting pin 39. During operation, the limiting pin 39 is rotated to the inner wall of the rotating plate 35 and the sliding plate 36, and the limiting pin 39 can restrict the position of the sliding plate 36 within the rotating plate 35.
[0027] The surface of the slide plate 36 is provided with multiple limiting holes, and the surface of the limiting pin 39 is threadedly connected to the inner wall of the limiting hole of the slide plate 36. During operation, the limiting pin 39 rotates to the inner wall of the limiting hole of the slide plate 36, and the opening of the limiting hole can accommodate the limiting pin 39.
[0028] The surface of the geomembrane 2 is provided with a prompting device 4, which includes a clamping plate 41. The clamping plate 41 is fitted onto the surface of the geomembrane 2. A storage plate 42 is fixedly connected to the bottom end of the clamping plate 41. A limiting block 43 is inserted into the inner surface of the storage plate 42. A prompting strip is provided on the inner surface of the storage plate 42. During operation, the prompting strip is inserted into the inner surface of the storage plate 42, and then the limiting block 43 is pushed to insert into the inner surface of the storage plate 42. Then, the clamping plate 41 is pushed to fit onto the surface of the geomembrane 2. By setting the clamping plate 41, the storage plate 42, and the limiting block 43, the position of the geomembrane 2 can be indicated to the personnel.
[0029] The inner wall of the clamping plate 41 is threaded with a threaded post 44, and the side wall of the threaded post 44 is rotatably connected with a clamping plate 45, which is located on one side of the geomembrane 2. During operation, the threaded post 44 is rotated to rotate on the inner wall of the clamping plate 41, and the threaded post 44 drives the clamping plate 45 to move. The clamping plate 45 will clamp the surface of the geomembrane 2. By setting the threaded post 44 and the clamping plate 45, the position of the clamping plate 41 can be restricted.
[0030] Working principle: When using pile 1, pry open the protective sleeve 31 and then push it to fit onto the surface of pile 1. Then, rotate the positioning pin 32 to the inner wall of the protective sleeve 31. Next, place the two support blocks 33 into appropriate positions on the surface of the protective sleeve 31. Then, insert the fixing pin 34 into the inner walls of the two support blocks 33 and the inner wall of the protective sleeve 31. Then, push the rotating plate 35 to rotate on the inner wall of the support blocks 33. After the rotating plate 35 rotates to the appropriate angle, pull the sliding plate 36 to slide on the inner wall of the rotating plate 35. After the sliding plate 36 slides to the appropriate position, rotate the limiting pin 39 to the inner wall of the rotating plate 35 and the inner wall of the limiting hole of the sliding plate 36. Then, rotate the rotating column 37 to adjust the orientation of the hole. Finally, insert the insertion rod 38 into the inner wall of the rotating column 37 and into the soil. By setting up the entire device, the geomembrane 2 can be protected, reducing wear on the surface of the pile rod 1. It can also assist in supporting the protective cylinder 31 and the pile rod 1, and reduce the possibility of the protective cylinder 31 moving randomly. After the geomembrane 2 is set up, the reflective strip is inserted into the inner surface of the storage plate 42. Then, the limiting block 43 is pushed to insert into the inner surface of the storage plate 42. Then, the clamping plate 41 is placed on the surface of the geomembrane 2. After the clamping plate 41 is placed, the threaded column 44 is rotated to rotate on the inner wall of the clamping plate 41. The threaded column 44 drives the clamping plate 45 to move. The clamping plate 45 presses the geomembrane 2 against the side wall of the storage plate 42. By setting up the entire device, the position of the geomembrane 2 can be indicated to personnel, thereby reducing the possibility of accidental contact with the geomembrane 2 at night.
