Description

Technical Field

[0001] This utility model belongs to the field of cofferdam technology for water conservancy construction, and specifically relates to a modular cofferdam structure for water conservancy construction. Background Technology

[0002] In the field of water conservancy construction, cofferdam structures are crucial temporary water-retaining structures. Their main function is to enclose a certain construction area during construction in rivers, lakes, and other water bodies, preventing water from entering and creating a dry and stable environment for construction, thus ensuring the smooth progress of water conservancy projects. With the continuous development of water conservancy construction technology and the increasing demands for construction efficiency and quality, modular cofferdam structures have gradually become a commonly used form of cofferdam in water conservancy construction due to their advantages such as flexible assembly, reusability, and strong adaptability. Existing modular cofferdam structures typically consist of multiple cofferdam panels and accordion-style protective covers connecting adjacent cofferdam panels. However, in actual water conservancy construction processes, existing modular cofferdam structures face some problems that urgently need to be addressed.

[0003] Currently, the cofferdam panels and accordion-style protective cover end plates are mostly connected by traditional bolts. On the one hand, bolt connections require tedious tightening and loosening operations, with each connection point requiring manual operation using tools. This not only consumes a lot of time and manpower, but also makes it difficult to quickly complete disassembly and assembly during actual construction, reducing the overall assembly convenience and construction efficiency. On the other hand, when the cofferdam structure needs to be dismantled after the completion of water conservancy construction, bolt connections also face the problem of difficult disassembly. A large number of bolts need to be removed one by one, which is not only inefficient, but also easily damages the cofferdam panels and accordion-style protective covers during dismantling, reducing their reuse rate and increasing construction costs. Therefore, this utility model proposes a modular cofferdam structure for water conservancy construction. Utility Model Content

[0004] The purpose of this invention is to provide a modular cofferdam structure for water conservancy construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular cofferdam structure for water conservancy construction, comprising cofferdam panels, a bellows-type protective cover installed between two cofferdam panels, and two end plates fixed at both ends of the bellows-type protective cover, wherein the end plates are connected to the cofferdam panels, and further comprising...

[0006] T-shaped splicing blocks fixed to the side of the end plate, and T-shaped splicing grooves opened on both ends of the cofferdam plate for the T-shaped splicing blocks to slide into;

[0007] And a locking mechanism is installed between the end plate and the cofferdam plate;

[0008] And a sealing plate fixed to the outer surface of the end plate, with the end of the sealing plate pressed tightly against the outer surface of the cofferdam plate.

[0009] Preferably, the locking limiting mechanism includes an L-shaped movable locking plate movably mounted on the inner surface of the end plate, and the end of the L-shaped movable locking plate extends to the inner surface of the cofferdam plate and is fixed with a limiting locking block. The inner surface of the cofferdam plate is provided with a limiting locking hole for the limiting locking block to be engaged.

[0010] Preferably, the locking limiting mechanism further includes an inner movable groove formed inside the end plate, an inner movable seat slidably installed in the inner movable groove, and a connecting block fixed on one side surface of the inner movable seat. The end of the connecting block extends through to the inner side of the end plate and is fixed to the L-shaped movable locking plate. A clamping spring is also installed on the inner side of the inner movable groove to clamp the inner movable seat, and the connecting block passes through the inner side of the clamping spring.

[0011] Preferably, one end of the clamping spring abuts against the inner wall of the inner movable groove, and the other end of the clamping spring abuts against the side of the inner movable seat.

[0012] Preferably, the side of the L-shaped movable plate is also fixed with two strip-shaped protrusions.

[0014] Preferably, the inner surface of the sealing plate is provided with two integrated sealing strips, and the outer surface of the dam plate is provided with a strip-shaped sealing groove for the sealing strips to be inserted.

[0015] Preferably, the sealing strip has a semi-circular cross-section, and the strip-shaped sealing groove has a rectangular cross-section.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: The modular cofferdam structure of this application achieves rapid assembly and disassembly between the cofferdam plate and the accordion-style protective cover end plate through a snap-fit ​​limiting mechanism. During assembly on the construction site, workers only need to connect the cofferdam plate and the accordion-style protective cover end plate through the snap-fit ​​limiting mechanism to quickly complete the connection, greatly shortening the assembly time and improving construction efficiency. At the same time, the snap-fit ​​limiting mechanism can ensure the stability after connection, making the entire modular cofferdam structure less prone to loosening and deformation when subjected to water flow impact, ensuring construction safety. In addition, the designed sealing structure can effectively prevent water from seeping in from the connection gaps, improving the sealing performance of the cofferdam and providing a more reliable guarantee for water conservancy construction. When dismantling after construction, the snap-fit ​​limiting mechanism can be separated with simple operation, which is convenient and quick, and will not damage the cofferdam plate and the accordion-style protective cover, improving the reuse rate of components and reducing construction costs.

After the T-shaped splicing block 5 slides into the inner side of the T-shaped splicing groove 6, the initial splicing between the end plate 2 and the cofferdam plate 1 can be realized.

[0026] And the snap-fit ​​limiting mechanism 7 set between the end plate 2 and the cofferdam plate 1 can complete the effective snap-fit ​​between the end plate 2 and the cofferdam plate 1, ensuring the rapid connection between the end plate 2 and the cofferdam plate 1 while ensuring the connection stability and improving the assembly convenience of the entire cofferdam structure.

[0027] The sealing plate 4 is glued and fixed to the outer surface of the end plate 2, and the end of the sealing plate 4 is pressed tightly against the outer surface of the cofferdam plate 1, which can ensure the sealing of the outer side of the joint between the end plate 2 and the cofferdam plate 1 and play a waterproof role.

[0028] In this embodiment, preferably, the locking limiting mechanism 7 includes an L-shaped movable locking plate 71 movably mounted on the inner surface of the end plate 2, and the end of the L-shaped movable locking plate 71 extends to the inner surface of the cofferdam plate 1 and is welded and fixed with a limiting block 72. The inner surface of the cofferdam plate 1 is provided with a limiting hole 73 for the limiting block 72 to be inserted. After actual splicing, the limiting block 72 is locked in the limiting hole 73, realizing a stable connection between the end plate 2 and the cofferdam plate 1 and ensuring the connection stability. The locking limiting mechanism 7 also includes an inner movable groove 74 opened inside the end plate 2, an inner movable seat 75 slidably mounted in the inner movable groove 74, and a connecting block 77 fixed on one side surface of the inner movable seat 75.

The inner side of the inner movable groove 74 is also equipped with a clamping spring 76 to press the inner movable seat 75 against it, and the connecting block 77 is fixed from the inner movable seat 75 to the inner movable groove 74. The inner side of the tension spring 76 passes through. During the initial assembly of the cofferdam plate 1 and end plate 2, the T-shaped splicing block 5 is first slid into the inner side of the T-shaped splicing groove 6. During the sliding process, the L-shaped movable plate 71 can be pulled forcefully towards the inner side of the end plate 2, causing the inner movable seat 75 to slide and further compress the tension spring 76, so that the limiting block 72 does not obstruct the smooth sliding of the T-shaped splicing block 5. When the T-shaped splicing block 5 smoothly slides into the inner side of the T-shaped splicing groove 6, and the end plate 2 is... When plate 2 and cofferdam plate 1 end face are aligned, the L-shaped movable clamping plate 71 can be loosened. Under the pushing action of the clamping spring 76, the inner movable seat 75 pulls the L-shaped movable clamping plate 71 back through the connecting block 77, so that the limiting clamping block 72 is engaged in the limiting clamping hole 73. This completes the rapid and stable splicing between end plate 2 and cofferdam plate 1, realizes the stable assembly between cofferdam plate 1 and bellows-type protective cover 3, and improves the ease of construction of the entire cofferdam structure at the water conservancy construction site.

[0029] In this embodiment, preferably, one end of the clamping spring 76 abuts against the inner wall of the inner movable groove 74, and the other end of the clamping spring 76 abuts against the side of the inner movable seat 75. Under the pushing action of the clamping spring 76, the L-shaped movable plate 71 can be tightly attached to the inner surface of the cofferdam plate 1 and the end plate 2 during daily use, and ensure that the limiting block 72 is stably locked in the limiting hole 73, so as to realize the stable assembly between the end plate 2 and the cofferdam plate 1.

The outer surface of the cofferdam plate 1 is provided with a strip-shaped sealing groove 11 for the sealing strips 41 to be inserted. When the end plate 2 and the cofferdam plate 1 are spliced ​​together, the sealing plate 4 is tightly attached to the outer surface of the cofferdam plate 1, and the sealing strips 41 are squeezed into the strip-shaped sealing groove 11 to achieve effective sealing and prevent water from seeping in.
