Description

Technical Field

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

[0002] A cofferdam is a temporary water-retaining structure used to create a dry working environment during construction in rivers, lakes, or coastal waters. It is constructed by using materials such as earth, sheet piles, concrete, or inflatable rubber dams to create a closed water-retaining zone, separating the construction area from the external water body. This facilitates foundation excavation, dam construction, and other operations. It is commonly used in bridge pier and sluice gate reconstruction projects and is a key technical measure to ensure the safety and efficiency of underwater construction.

[0003] Most existing cofferdam devices do not have the function of mitigating the impact of water flow. When the water flow is rapid, the cofferdam will directly bear the violent impact of the water flow, which can easily cause structural deformation or collapse and affect the overall stability of the cofferdam. In addition, most existing cofferdam devices are generally integrally formed, which makes transportation difficult and requires a long time for installation and dismantling, thus affecting the overall construction progress.

[0004] Therefore, those skilled in the art have provided a cofferdam device for water conservancy engineering construction to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cofferdam device for water conservancy engineering construction. This cofferdam device involves the first locking block of a first locking plate engaging with the first locking groove of a third locking plate, then the second locking block of a second locking plate engaging with the second locking grooves of other second locking plates, and finally the third locking block being simultaneously placed into the fourth locking groove and the third locking groove. Through the provided external and internal splicing mechanisms, transportation is not only more convenient, but also facilitates the rapid installation and disassembly of the cofferdam.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A cofferdam device for water conservancy construction includes an external splicing mechanism and a filling chamber. The external splicing mechanism includes multiple first snap-fit ​​plates and multiple third snap-fit ​​plates. Both ends of the first snap-fit ​​plates are fixedly connected to first snap-fit ​​blocks. Both ends of the third snap-fit ​​plates are provided with first snap-fit ​​grooves. The inner walls of the first snap-fit ​​plates are provided with third snap-fit ​​blocks. The outer splicing mechanism is internally provided with an inner splicing mechanism. The inner splicing mechanism includes a plurality of second snap-fit ​​plates disposed inside the outer splicing mechanism. Each of the second snap-fit ​​plates has a second snap-fit ​​groove at one end. Each of the second snap-fit ​​plates has a second snap-fit ​​block fixedly connected to the end of the second snap-fit ​​plate away from the second snap-fit ​​groove. Each of the second snap-fit ​​plates has a reinforcing ring on its inner wall and a fourth snap-fit ​​groove on its outer wall. The front end of the external splicing mechanism is provided with a buffer mechanism, which includes multiple fixed rods fixedly connected to the outer wall of the front end of the third front end snap plate. The rod body of each fixed rod is fixedly connected to a second buffer plate, and the outer wall of the front end of each fixed rod is fixedly connected to a first buffer plate. Through the above technical solution, the cofferdam device is connected by the first locking block of the first locking plate and the first locking groove of the third locking plate. Then, the second locking block of the second locking plate is connected with the second locking groove of other second locking plates. Then, the third locking block is simultaneously placed into the fourth locking groove and the third locking groove. Through the set external splicing mechanism and internal splicing mechanism, it is not only more convenient to transport, but also convenient to quickly install and disassemble the cofferdam.

[0007] Furthermore, the first snap-fit ​​plate is arc-shaped, and the first snap-fit ​​plate and the third snap-fit ​​plate are snap-fitted together; The above technical solution uses an arc-shaped first snap-fit ​​plate to reduce the impact of water flow. The first snap-fit ​​plate and the third snap-fit ​​plate are snapped together to allow them to be joined together.

[0008] Furthermore, the outer wall of the second snap-fit ​​plate is provided with a fourth snap-fit ​​groove, and the inner wall of the first snap-fit ​​plate is provided with a third snap-fit ​​groove. The fourth snap-fit ​​groove and the third snap-fit ​​groove are connected by a third snap-fit ​​block. With the above technical solution, the first and second carding plates can be spliced ​​together by connecting the fourth and third carding slots to the third carding block.

[0009] Furthermore, the first snap-fit ​​plate and the second snap-fit ​​plate are engaged by a third snap-fit ​​block; The above technical solution allows the first and second snap-fit ​​plates to be spliced ​​together.

[0010] Furthermore, the multiple second snap-fit ​​plates engage with each other, and the second snap-fit ​​blocks and second snap-fit ​​slots engage with each other. The above technical solution allows multiple second connector plates to be spliced ​​together.

[0011] Furthermore, positioning brackets are fixedly connected to both sides of the inner wall of the plurality of second snap-fit ​​plates, and the reinforcing ring engages with the positioning brackets. The above technical solution provides support for the inner wall of the second snap-fit ​​plate.

[0012] Furthermore, the guide groove of the first buffer plate is inclined; The above technical solution can thus absorb the impact force of the water flow.

[0013] This utility model has the following beneficial effects: 1. The present invention proposes a cofferdam device for water conservancy engineering construction. Compared with most existing cofferdam devices, this cofferdam device uses a first locking block of a first locking plate to lock with a first locking groove of a third locking plate. Then, the second locking block of a second locking plate locks with the second locking grooves of other second locking plates. Finally, the third locking block is simultaneously placed into the fourth locking groove and the third locking groove. Through the external and internal splicing mechanisms, it is not only more convenient to transport, but also facilitates the rapid installation and disassembly of the cofferdam.

[0014] 2. The cofferdam device for water conservancy construction proposed in this utility model, compared with most existing cofferdam devices, disperses the turbulent water flow through a first buffer plate, then weakens the impact force of the water flow through a second buffer plate, and then prevents water from flowing into the cofferdam from the joint gaps by the reinforcing ring and the filling chamber filled with sand and gravel. Through the buffer mechanism, the impact force of the water can be weakened, thus ensuring the stability of the cofferdam device. Attached Figure Description

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.

[0018] Reference Figure 1 , Figure 2 and Figure 3 One embodiment provided by this utility model: A cofferdam device for water conservancy construction includes an outer splicing mechanism 3 and a filling chamber 5. The outer splicing mechanism 3 includes a plurality of first snap-fit ​​plates 301 and a plurality of third snap-fit ​​plates 303. Both ends of the first snap-fit ​​plates 301 are fixedly connected to first snap-fit ​​blocks 304. Both ends of the third snap-fit ​​plates 303 are provided with first snap-fit ​​grooves 302. The inner wall of the first snap-fit ​​plates 301 is provided with third snap-fit ​​blocks 306. The outer splicing mechanism 3 is internally equipped with an inner splicing mechanism 6. The inner splicing mechanism 6 includes multiple second snap-fit ​​plates 601 disposed inside the outer splicing mechanism 3. Each second snap-fit ​​plate 601 has a second snap-fit ​​groove 603 at one end. Each second snap-fit ​​plate 601 is fixedly connected to a second snap-fit ​​block 602 at the end away from the second snap-fit ​​groove 603. Each second snap-fit ​​plate 601 has a reinforcing ring 1 on its inner wall and a fourth snap-fit ​​groove 604 on its outer wall. The front end of the outer splicing mechanism 3 is provided with a buffer mechanism 4. The buffer mechanism 4 includes multiple fixed rods 403 fixedly connected to the outer wall of the front end of the third front snap plate 303. The rod body of each fixed rod 403 is fixedly connected to a second buffer plate 401, and the outer wall of the front end of each fixed rod 403 is fixedly connected to a first buffer plate 402. The cofferdam device is connected by the first locking block 304 of the first locking plate 301 to the first locking groove 302 of the third locking plate 303. Then, the second locking block 602 of the second locking plate 601 is connected to the second locking groove 603 of the other second locking plates 601. Then, the third locking block 306 is simultaneously placed into the fourth locking groove 604 and the third locking groove 305. With the external splicing mechanism 3 and the internal splicing mechanism 6, it is not only more convenient to transport, but also facilitates the rapid installation and disassembly of the cofferdam.

[0019] Reference Figure 2 , Figure 3 and Figure 4 The first retaining plate 301 is arc-shaped, and it engages with the third retaining plate 303. The arc shape of the first retaining plate 301 reduces the impact force from the water flow. The engagement of the first and third retaining plates 301 allows them to be joined together. The outer wall of the second retaining plate 601 is provided with a fourth retaining groove 604, and the inner wall of the first retaining plate 301 is provided with a third retaining groove. The fourth and third slots 305 are connected by a third slot block 306. Both the fourth and third slots 604 are connected to the third slot block 306, thus allowing the first and second slot plates 301 to be joined together. The first and second slot plates 301 are joined together by the third slot block 306.

[0020] Reference Figure 3 and Figure 5 Multiple second snap-fit ​​plates 601 are interlocked with each other, and second snap-fit ​​blocks 602 and second snap-fit ​​grooves 603 are interlocked with each other, so that multiple second snap-fit ​​plates 601 can be spliced ​​together. Positioning brackets 2 are fixedly connected to both sides of the inner wall of multiple second snap-fit ​​plates 601. Reinforcing rings 1 are interlocked with positioning brackets 2, thereby supporting the inner wall of the second snap-fit ​​plates 601. The guide groove of the first buffer plate 402 is inclined, which can absorb the impact force of the water flow.

[0021] Working principle: During assembly, multiple second snap-fit ​​plates 601 are first spliced ​​together using second snap-fit ​​blocks 602 and second snap-fit ​​grooves 603. Then, the first snap-fit ​​block 304 of the first snap-fit ​​plate 301 is spliced ​​with the first snap-fit ​​groove 302 of the third snap-fit ​​plate 303. After installation, the third snap-fit ​​block 306 is inserted into the third snap-fit ​​groove 305 and the fourth snap-fit ​​groove 604 for snap-fit. Then, sand and gravel are filled into the filling chamber 5 to increase the stability of the cofferdam device and prevent water from entering the cofferdam from the splicing gaps. The reinforcing ring 1 is then placed into the positioning bracket 2 to increase the internal support of the cofferdam device. During installation, the second buffer plate 401 and the first buffer plate 402 are installed on the water-facing side. When the water flow is rapid, the first buffer plate 402 can disperse the water flow, and the second buffer plate 401 can weaken the dispersed water flow. The first snap-fit ​​plate 301 is arc-shaped, which can effectively reduce the impact force of the water flow.
