Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a temporary cofferdam structure for water conservancy construction. Background Technology

[0002] In the construction of water conservancy projects, the difficulty is often much greater than that of dryland projects. The first step is to isolate the water source, and the cofferdam method is the most commonly used method in water conservancy projects. Among the cofferdam methods, steel sheet pile cofferdams are most often used for construction. However, steel sheet pile cofferdams have certain limitations and take a long time to construct. In some lakes or rivers, they are overkill. Secondly, traditional cofferdams occupy a large area and are not convenient to dismantle and transport. Therefore, we propose a temporary cofferdam structure for water conservancy construction. Utility Model Content

[0003] The main objective of this invention is to provide a temporary cofferdam structure for water conservancy construction, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A temporary cofferdam structure for water conservancy construction includes a positioning cone, with a cone head fixedly connected to the bottom of each positioning cone. Water-proof plates are tenon-and-mortise connected to both sides of the positioning cone, and fixing plates are fixedly connected to the outer side of each water-proof plate. The ends of the fixing plates on the same side are slidably connected by connecting columns.

[0006] Preferably, the water-blocking plate includes a partition plate, and rectangular protrusions are fixedly connected to both the left and right ends of the partition plate. Four rectangular protrusions are fixed on the front and back sides of the partition plate, and the four rectangular protrusions are symmetrically distributed near the left and right sides. Any one of the rectangular protrusions can be slidably connected to the fixed groove.

[0007] By adopting the above technical solution: the partition plate can work with the positioning cone to provide support and prevent water from entering. Rectangular protrusions are fixedly connected to both ends of the partition plate, and the rectangular protrusions can be used to cooperate with the fixing grooves on the positioning cone. Four rectangular protrusions are fixed on the front and back sides of the partition plate, and the four rectangular protrusions are symmetrically distributed near the left and right sides. The rectangular protrusions on both sides can make the connection point turn 90 degrees, so that the cofferdam can be pieced together into a closed rectangle. The device uses a mortise and tenon structure to make the connection point tight and seamless, which can prevent water from entering and is very stable.

[0008] Preferably, the positioning cone includes a fixing post, the top of which is threadedly connected to a top cover. The fixing post is partially hollow and can hold a small amount of water. The fixing post is symmetrically fixedly connected to fixing grooves on its left and right sides.

[0009] By adopting the above technical solution: the positioning cone can be inserted into the ground with the cone head to be firmly fixed and play a major role in supporting the device. The top of the fixed column is threaded with a top cover, which can be opened to add a small amount of water into the fixed column. After the fixed column is filled with water, it will play a role in relieving pressure. The fixed column is symmetrically provided with fixing grooves on the left and right sides to cooperate with the rectangular protrusions, which can reduce the impact of water waves or water flow, reduce the swaying amplitude, increase safety performance, and greatly increase the stability of the cofferdam device.

[0010] Preferably, the fixing plate includes a connecting plate, and two vertically arranged triangular plates are fixedly connected to the top of the connecting plate, with the right-angled sides of the triangular plates flush with the rear side of the connecting plate.

[0011] By adopting the above technical solution: the connecting plate is fixedly connected to the bottom of the water-proof plate. When in use, burying the connecting plate in the soil can further fix the water-proof plate. The two triangular plates utilize the stability of triangles to further and more firmly connect the water-proof plate and the connecting plate.

[0012] Preferably, the top of the fixing column is provided with a thread for use with the top cover, and the outer side of the top cover is provided with anti-slip texture. One end of the water-blocking plate can be connected to multiple positioning cones, and they do not affect each other.

[0013] By adopting the above technical solution: the fixed column and the top cover are threaded together, which can effectively prevent water leakage. The outer side of the top cover is also provided with anti-slip texture to prevent workers from slipping when their hands are wet during water conservancy construction. Multiple positioning cones can be connected to one end of the water-blocking plate, and they do not affect each other. This allows for more flexible combination of the water-blocking plate and the positioning cones, improving the flexibility of the device.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the positioning cone can be inserted into the ground with the cone head to be firmly fixed and play a major role in supporting the device. The top of the fixing column is threaded with a top cover, which can be opened to add a small amount of water into the fixing column. After the fixing column is filled with water, it will play a role in relieving force. The fixing column is symmetrically provided with fixing grooves on the left and right sides to cooperate with the rectangular protrusions, which can reduce the impact of water waves or water flow, reduce the swaying amplitude, increase safety performance, and greatly increase the stability of the cofferdam device.

[0016] 2. In this utility model, rectangular protrusions are fixedly connected to both ends of the partition plate. The rectangular protrusions can be used in conjunction with the fixing grooves on the positioning cones. Four rectangular protrusions are fixed on the front and back sides of the partition plate, and the four rectangular protrusions are symmetrically distributed near the left and right sides. The rectangular protrusions on both sides can make the connection point turn at 90 degrees, so that the cofferdam can be pieced together into a closed rectangle. The device uses a mortise and tenon structure to make the connection point tight and seamless. Multiple positioning cones can be connected to one end of the water-proof plate, and they do not affect each other. This allows for more flexible combination methods of the water-proof plate and the positioning cones, improving the flexibility of the device. Attached Figure Description

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A temporary cofferdam structure for water conservancy construction includes a positioning cone 1, with a cone head 5 fixedly connected to the bottom of each positioning cone 1. Water-proof plates 2 are tenon-and-mortise connected to both sides of the positioning cone 1. Fixing plates 3 are fixedly connected to the outer side of each water-proof plate 2. The ends of the fixing plates 3 on the same side are slidably connected by connecting columns 4.

[0027] In this embodiment, the water-blocking plate 2 includes a partition plate 21, with rectangular protrusions 22 fixedly connected to both the left and right ends of the partition plate 21. Four rectangular protrusions 22 are fixed to the front and back sides of the partition plate 21, and the four rectangular protrusions 22 are symmetrically distributed near the left and right sides. Any one of the rectangular protrusions 22 can be slidably connected to the fixing groove 13. The fixing plate 3 includes a connecting plate 31, with two vertically arranged triangular plates 32 fixedly connected to the top of the connecting plate 31. The right-angled side of the triangular plate 32 is flush with the rear side of the connecting plate 31. Multiple positioning cones 1 can be connected to one end of the water-blocking plate 2, and they do not affect each other.

[0028] With the above scheme: rectangular protrusions 22 are fixedly connected to both ends of the partition plate 21, and the rectangular protrusions 22 can be used in conjunction with the fixing grooves 13 on the positioning cones 1. Four rectangular protrusions 22 are fixed on the front and back sides of the partition plate 21, and the four rectangular protrusions 22 are symmetrically distributed near the left and right sides. The rectangular protrusions 22 on both sides can make the connection point turn 90 degrees, so that the cofferdam can be pieced together into a closed rectangle. The device uses a mortise and tenon structure to make the connection point tight and seamless. Multiple positioning cones 1 can be connected to one end of the partition plate 21, and they do not affect each other. This allows for more flexible combination methods of the water-blocking plate 2 and the positioning cones 1, improving the flexibility of the device.

[0029] In this embodiment, the positioning cone 1 includes a fixing post 11, the top of which is threadedly connected to a top cover 12. The fixing post 11 is partially hollow and can hold a small amount of water. The fixing post 11 is symmetrically fixedly connected to fixing grooves 13 on the left and right sides. The fixing plate 3 includes a connecting plate 31, the top of which is fixedly connected to two vertically arranged triangular plates 32, and the right-angled sides of the triangular plates 32 are flush with the rear side of the connecting plate 31.

[0030] Through the above scheme: the positioning cone 1 can be inserted into the ground with the cone head 5 and can be firmly fixed, playing a major role in supporting the device. The top of the fixing column 11 is threaded with a top cover 12, which can be opened to add a small amount of water to the fixing column 11. After adding water, the fixing column 11 will play a role in relieving pressure. The fixing column 11 is symmetrically provided with fixing grooves 13 that cooperate with the rectangular protrusions 22, which can reduce the impact of water waves or water flow, reduce the swaying amplitude, increase safety performance, and greatly increase the stability of the cofferdam device.

[0031] It should be noted that this utility model is a temporary cofferdam structure for hydraulic construction. First, a positioning cone 1 is driven into the terrain where hydraulic construction is needed using a machine. Because the device utilizes a mortise and tenon structure, the precision required for driving the positioning cone 1 into place is very high; otherwise, the water-blocking plate 2 may not be able to fit in. After the positioning cone 1 is laid, the water-blocking plate 2 is then inserted into the laid positioning cone 1 in sequence, with the end of the water-blocking plate 2 with the fixing plate 3 facing downwards and buried in the soil. The top of the fixing column 11 is threadedly connected to a top cover 12, which can be opened to add a small amount of water to the fixing column 11. Adding water to the fixing column 11 will have a stress-relieving effect. The fixed column 11 is symmetrically provided with fixing grooves 13 that cooperate with the rectangular protrusions 22. This can reduce the impact of water waves or currents, reduce the swaying amplitude, increase safety performance, and greatly increase the stability of the cofferdam device. The device uses a mortise and tenon structure to ensure that the connection is tight and seamless. Moreover, one end of the water-proof plate 2 can be connected to multiple positioning cones 1, and they do not affect each other. This allows for more flexible combination methods of the water-proof plate 2 and the positioning cones 1, improving the flexibility of the device. There are many other assembly methods for the device. The figure only shows one of them. There are many more convenient and stable structures. All the above components work together to make the device more convenient and efficient.
