Description

Technical Field

[0001] This utility model relates to the field of water conservancy cofferdam technology, and in particular to a structurally stable water conservancy cofferdam device. Background Technology

[0002] A cofferdam is a temporary retaining structure built in water conservancy projects to construct permanent water conservancy facilities. Its function is to prevent water or soil from entering the construction site of the building so that drainage can be carried out within the cofferdam, foundation pits can be excavated, and buildings can be constructed. It is usually equipped with a retaining wall for blocking the water.

[0003] However, in actual use, the existing hydraulic cofferdam devices still have the following problems:

[0004] In terms of structural installation, some cofferdams adopt integral structures or traditional splicing methods, which are complicated to install and require a lot of on-site welding, pouring and other operations. This not only results in low installation efficiency, but also places high demands on the construction site and equipment, making it difficult to build quickly. In terms of stability, the support structure of traditional cofferdams is mostly of fixed size, which is difficult to adapt to construction areas of different shapes and sizes. Under complex water flow or geological conditions, it is easy to have uneven local stress and poor stability, and even tilting or collapse. In terms of maintenance and transportation, integral or non-modular cofferdams occupy a lot of space and cost during transportation. Moreover, if a component is damaged during later maintenance, it is often necessary to disassemble and repair the entire structure, which is difficult and costly.

[0005] In response to this technical problem, this application proposes a structurally stable hydraulic cofferdam device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as cumbersome installation, low efficiency, and difficulty in adapting support structures to different construction size requirements. This invention proposes a structurally stable hydraulic cofferdam device. The device achieves rapid installation through modular assembly, improving efficiency and stability, and facilitating transportation and maintenance. The internal support rods are adjustable to adapt to different construction sizes, and the bottom support block inserts and connecting frame teeth form a three-dimensional anchor, enhancing adaptability to complex geological conditions and resistance to water flow impact.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A structurally stable hydraulic cofferdam device includes corner columns. Each corner column has an installation groove on its adjacent side. A connecting frame is detachably connected to the inner wall of each installation groove. The connecting frame is connected to a bottom support block and a top support block via an installation assembly. The top of the bottom support block is connected to the top support block via a connecting assembly. A sliding groove is provided at the front end of the connecting frame on its adjacent side. A water-blocking plate is detachably connected to the inner wall of the sliding groove. A support sleeve rod is rotatably connected to the top end of the corner column on its adjacent side, and a second support sleeve rod is rotatably connected to the bottom end of the corner column on its adjacent side. Both support sleeve rods are connected to connecting rods via positioning assemblies.

[0009] Furthermore, the mounting assembly includes a mounting block and a second mounting groove. The mounting block is fixedly connected to the rear end of the connecting frame on the same side. The second mounting groove is opened on the left and right sides of the bottom support block and the top support block. The mounting block and the second mounting groove are detachably connected.

[0010] Furthermore, both the first mounting groove and the second mounting groove are dovetail-shaped.

[0011] Furthermore, the connecting component includes a slot, which is formed on the top of the bottom support block. Both the bottom side of the inner wall of the slot and the top of the top support block have through holes, and the inner wall of the through holes is detachably connected to a plug rod.

[0012] Furthermore, the positioning component includes a positioning hole and a fixing bolt. The positioning hole is opened on the front side of the outer wall of the first and second support sleeves, and the fixing bolt is opened on the front side of the connecting rod.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3An embodiment of this utility model provides a structurally stable hydraulic cofferdam device, including corner columns 1. Each corner column 1 has an installation groove 2 on a side adjacent to it. A connecting frame 3 is detachably connected to the inner wall of the installation groove 2. The connecting frame 3 is connected to a bottom support block 5 and a top support block 7 via an installation component 9. The top of the bottom support block 5 is connected to the top support block 7 via a connecting component 6. A sliding groove 4 is provided at the front end of the connecting frame 3 on a side adjacent to it. A water-blocking plate 8 is detachably connected to the inner wall of the sliding groove 4. A support sleeve rod 10 is rotatably connected to the top end of the corner column 1 on a side adjacent to it. A support sleeve rod 21 is rotatably connected to the bottom end of the corner column 1 on a side adjacent to it. Both support sleeve rod 10 and support sleeve rod 21 are connected to a connecting rod 14 via a positioning component 13.

[0027] Specifically, the mounting slot 2 on the side adjacent to the corner post 1 is detachably connected to the connecting frame 3. Combined with the dovetail-shaped mounting slots 2 and 902, and the detachable connection between the mounting block 901 and mounting slot 902, a modular assembly design is achieved. During installation and use, the components can be spliced ​​together modularly. Compared to traditional cofferdam devices, this method results in a tighter connection between components, mutually constraining each other to form a stable overall structure, greatly enhancing the cofferdam's robustness. On one hand, the dovetail design has excellent guiding and positioning functions, enabling quick and accurate splicing of components during installation, improving installation efficiency. On the other hand, the dovetail structure effectively prevents displacement of components in the horizontal and vertical directions, further enhancing connection stability. Moreover, the detachable connection method facilitates disassembly of components during transportation, reducing transportation volume and costs. It also makes later maintenance or component replacement more convenient; only the corresponding connection points need to be disassembled for operation, eliminating the need for large-scale dismantling and reconstruction of the entire cofferdam. The connecting frame 3 connects the bottom support block 5 and the top support block 7, and the bottom support block 5 and the top support block 7 are connected. The water-retaining plate 8 is detachably connected in the sliding groove 4 of the connecting frame 3, further enhancing the overall stability. The bottom support block 5 and the top support block 7 provide vertical support and constraint for the entire structure, making the connecting frame 3 more stable and reducing deformation caused by external forces. The water-retaining plate 8 is installed through the sliding groove 4, which is not only convenient to install, but also allows it to fit tightly against the connecting frame 3, forming a good water-retaining effect, effectively blocking the impact of water flow, and also facilitating quick replacement when the water-retaining plate 8 is damaged. In addition, this structural design allows the force to be evenly distributed to various components when the cofferdam is impacted by water flow, avoiding excessive local stress that could lead to damage and extending the service life of the cofferdam.

[0028] Meanwhile, the support sleeve rod 10 and support sleeve rod 11, which are rotatably connected to the corner column 1, are connected to the connecting rod 14 through positioning holes 1301, screw holes 1302, and fixing bolts 1303. The front connecting rod 14 and the rear connecting rod 14 are connected through fixing bolts 15, forming a flexibly adjustable support system. Unlike existing internal support rods, which are mostly fixed in size and cannot adapt to different construction size requirements, in this device, the support sleeve rod 10, support sleeve rod 11, and connecting rod 14 are connected by threads through positioning holes 1301, screw holes 1302, and fixing bolts 1303. This allows for flexible adjustment of the connection position and angle between the connecting rod 14 and the support sleeve rods 10 and 11 according to the actual size requirements of the construction site, thereby changing the shape and size of the entire support system to adapt to different construction size requirements. This flexible adjustment method makes the cofferdam device highly versatile and adaptable, applicable to various water conservancy engineering construction sites of different specifications and shapes, greatly improving the device's scope of use and value. Furthermore, if site dimensions change or adjustments to the cofferdam are needed during construction, there is no need to redesign and manufacture new support structures; only simple adjustments to the existing support system are required, saving time and costs. Additionally, by adjusting the angle and position of the support system, the stress distribution of the cofferdam can be optimized, ensuring better stability and safety under different water flow conditions and operating circumstances.

[0029] Reference Figures 2-4 The mounting component 9 includes a mounting block 901 and a mounting groove 902. The mounting block 901 is fixedly connected to the rear end of the connecting frame 3 on the same side. The mounting groove 902 is opened on the left and right sides of the bottom support block 5 and the top support block 7. The mounting block 901 and the mounting groove 902 are detachably connected. Both the mounting groove 2 and the mounting groove 902 are dovetail shaped. The connecting component 6 includes a slot 601, which is opened on the top of the bottom support block 5. The bottom side of the inner wall of the slot 601 and the top of the top support block 7 are provided with through holes 602. A rod 603 is detachably connected to the inner wall of the through hole 602. The positioning component 13 It includes a positioning hole 1301 and a fixing bolt 1303. The positioning hole 1301 is opened on the front side of the outer wall of the support sleeve rod 10 and the support sleeve rod 2 11. The fixing bolt 1303 is opened on the front side of the connecting rod 14. The inner wall of the positioning hole 1301 is threaded with a screw hole 1302. The screw hole 1302 passes through the positioning hole 1301 and is threadedly connected to the inner wall of the fixing bolt 1303. The front connecting rod 14 is connected to the rear connecting rod 14 through the fixing bolt 2 15. The bottom of the corner post 1 is fixedly connected with a bottom post 16. The bottom of the bottom support block 5 is fixedly connected with an insert plate 17. The bottom of the connecting frame 3 is fixedly connected with a tooth 12.

[0030] Specifically, during operation, the bottom column 16 at the base of the corner column 1 and the insert plate 17 at the base of the bottom support block 5 can penetrate deep into the foundation, enhancing the connection stability between the cofferdam device and the foundation. The design of the bottom column 16 and the insert plate 17 acts like a "stabilizing anchor" for the cofferdam device, effectively preventing settlement and tilting of the cofferdam due to insufficient foundation bearing capacity. This is especially suitable for construction environments with loose soil, significantly improving the adaptability of the cofferdam under complex geological conditions. Meanwhile, the teeth 12 at the bottom of the connecting frame 3 can be embedded in the ground to prevent horizontal displacement of the cofferdam under the impact of water flow. The teeth 12 act like "anti-slip nails," firmly gripping the ground. Working in conjunction with the bottom column 16 and the insert plate 17, they construct a stable three-dimensional anchoring system in both vertical and horizontal directions, enabling the cofferdam to remain stable even under the impact of turbulent water flow, greatly reducing the risk of leakage and collapse due to displacement.

[0031] During installation, the corner post 1 is first fixed in the designated position using the base post 16. Then, the connecting frame 3 is embedded into the mounting groove 2 of the corner post 1. Next, the bottom support block 5 and the top support block 7 are connected and fixed to their own mounting grooves 902 via the mounting block 901. Then, the water-blocking plate 8 is installed in the sliding groove 4. Afterward, according to the dimensions of the construction site, the angles of the support sleeve rod 10 and the support sleeve rod 11 are adjusted, and the connecting rod 14 is installed in the appropriate position through the positioning hole 1301, screw hole 1302, and fixing bolt 1303. Finally, the front and rear connecting rods 14 are connected with the fixing bolt 15 to complete the construction of the entire cofferdam device, forming a stable and flexible hydraulic cofferdam structure that can adapt to different construction dimensions. This installation process is clear and simple, requiring no complex professional equipment, allowing construction personnel to quickly get started, greatly shortening the construction cycle and reducing labor costs. Meanwhile, the modular design of each component facilitates on-site transportation and storage. During installation, the precise detachable connection between each component ensures installation accuracy and allows for quick disassembly and adjustment in case of installation errors or later maintenance. This effectively improves construction efficiency and the convenience of later maintenance of the cofferdam, providing a strong guarantee for the safe and efficient advancement of water conservancy project construction.

[0032] Working principle: Before installation, the corner column 1 is fixed in the designated position by the bottom column 16 at the bottom of the corner column 1. Then, the connecting frame 3 is embedded into the installation groove 2 of the corner column 1. Next, the bottom support block 5 and the top support block 7 are connected and fixed to their own installation groove 902 through the installation block 901. Then, the water baffle 8 is installed in the sliding groove 4 of the connecting frame 3. After that, according to the size of the construction site, the angles of the support sleeve rod 10 and the support sleeve rod 2 11 are adjusted. The connecting rod 14 is installed in place through the positioning hole 1301, screw hole 1302 and fixing bolt 1303. The front and rear connecting rods 14 are connected with the fixing bolt 2 15 to complete the construction. During this process, the insert plate 17 at the bottom of the bottom support block 5 is inserted into the foundation and the teeth 12 at the bottom of the connecting frame 3 are embedded in the ground. Together with the bottom column 16, they ensure that the cofferdam is stable and resists the impact of water flow.
