Description

Technical Field

[0001] This utility model relates to the field of anti-seepage cofferdam technology, specifically an anti-seepage cofferdam quick connection structure for underwater construction. Background Technology

[0002] A cofferdam is a temporary retaining structure built in water conservancy projects. Its function is to prevent water and soil from entering the construction site of the structure. It is mainly used to intercept water flow, prevent leakage, ensure construction safety, and facilitate drainage, excavation of foundation pits, and construction of structures within the cofferdam. Existing cofferdam construction structures have poor seepage prevention effects and insufficient structural strength, which limits their enclosure function and prevents rapid assembly.

[0003] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a quick connection structure for seepage-proof cofferdams for underwater construction. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a quick-connect structure for seepage-proof cofferdams used in underwater construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-connect structure for an anti-seepage cofferdam used in underwater construction, comprising a modular cofferdam plate, a connecting frame, and reinforcing strips. A reinforcing rear plate is fixed to the rear side of the modular cofferdam plate. A splicing block is vertically fixed to the left side of the modular cofferdam plate, and a T-shaped locking block is integrally fixed to the front end of the splicing block. A connecting frame is fixed to the right side of the modular cofferdam plate, and a splicing slot is provided on the inner side of the connecting frame. A rubber sealing layer is bonded to the inner side of the splicing slot, and a water-swellable waterstop is provided on the inner side of the rubber sealing layer. Multiple reinforcing strips are fixed at equal intervals on one side of the connecting frame. The front side of the reinforcing strip has an arc-shaped protrusion structure, and the reinforcing strip is located on the front side of the modular cofferdam plate and is in contact with the surface of the modular cofferdam plate.

[0006] Furthermore, the surfaces of the modular cofferdam plate and the reinforced rear plate are both provided with anti-corrosion coatings, and the reinforced rear plate has a wavy structure.

[0007] Furthermore, the modular cofferdam plate, splicing block, and connecting frame are an integrated structure, and the connecting frame is U-shaped.

[0008] Furthermore, the shape of the splicing slot matches the shape of the splicing block and the T-shaped card block, and the splicing block, the T-shaped card block and the splicing slot are interlocked.

[0009] Furthermore, a storage frame is fixed to the lower rear side of the modular cofferdam plate, and an auxiliary support component is installed inside the storage frame.

[0010] Furthermore, the auxiliary support assembly includes a damping shaft, a collar, and a locking bolt. The damping shaft is rotatably mounted on the upper inner side of the storage frame, and a collar is slidably sleeved on the outer side of the damping shaft, with a locking bolt passing through the collar.

[0011] Furthermore, the auxiliary support assembly also includes a telescopic rod and an anchoring nail. The telescopic rod is installed on the lower side of the collar, and the bottom of the telescopic rod is fixed with an anchoring nail.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. Equipped with a connecting frame and reinforcing strips, when the modular cofferdam panels are spliced ​​in pairs, the splicing block and T-shaped clip of one modular cofferdam panel are slidably installed into the splicing slot of the other modular cofferdam panel, realizing rapid splicing of the modular cofferdam panels. The shape of the splicing slot can extend the leakage path. The interlocking design of the splicing block, T-shaped clip and splicing slot makes it difficult for the spliced ​​single modular cofferdam panel to move left or right or back and forth, and the connection is relatively stable. During the connection process, the splicing block, T-shaped clip and the rubber sealing layer and water-swellable waterstop inside the splicing slot are tightly fitted to form an initial sealing structure. The water-swellable waterstop can expand when exposed to water to fully compensate for the joint gap, further playing a role in preventing leakage.

[0013] 2. Equipped with connecting frames and reinforcing strips, the modular cofferdam plate is made of composite steel plate with an internally filled polyurethane foam insulation and waterproof layer. The reinforced rear plate with a wavy structure is fixed to the rear side of the modular cofferdam plate to improve its structural strength. During splicing, the ends of the reinforcing strips evenly distributed on one side of the connecting frame of the modular cofferdam plate can fit into the connecting frame of another modular cofferdam plate, thereby limiting and securing the connecting frame and providing effective support to prevent deformation of the connecting frame. The front side of the reinforcing strip has an arc-shaped protrusion structure that can play an impact-resistant role, thereby providing a certain degree of protection for the modular cofferdam plate. The auxiliary support components can support the modular cofferdam plate and improve its stability. Attached Figure Description

Detailed Implementation

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. The following examples are used to illustrate this utility model, but should not be used to limit the scope of protection of this utility model.

[0017] like Figure 1 , Figure 2 and Figure 5 As shown in the figure, a quick-connect structure for an anti-seepage cofferdam used in underwater construction in this embodiment includes a modular cofferdam plate 1, a connecting frame 5, and a reinforcing strip 9. A reinforcing rear plate 2 is fixed to the rear side of the modular cofferdam plate 1. Both the surface of the modular cofferdam plate 1 and the reinforcing rear plate 2 are provided with an anti-corrosion coating, and the reinforcing rear plate 2 has a wavy structure. Specifically, the modular cofferdam plate 1 can be a composite steel plate with an internally filled polyurethane insulation and waterproof layer. The reinforcing rear plate 2 with a wavy structure is fixed to the rear side of the modular cofferdam plate 1 to improve its structural strength.

[0018] like Figure 2 and Figure 3 As shown, a splicing block 3 is vertically fixed to the left side of the modular cofferdam panel 1, and a T-shaped locking block 4 is integrally fixed to the front end of the splicing block 3. A connecting frame 5 is fixed to the right side of the modular cofferdam panel 1, and a splicing slot 6 is provided on the inner side of the connecting frame 5. A rubber sealing layer 7 is bonded to the inner side of the splicing slot 6, and a water-swellable waterstop 8 is provided on the inner side of the rubber sealing layer 7. The modular cofferdam panel 1, the splicing block 3, and the connecting frame 5 are an integrated structure, and the connecting frame 5 is U-shaped. The shape of the splicing slot 6 on the inner side of the connecting frame 5 matches the shape of the splicing block 3 and the T-shaped locking block 4, and the splicing block 3, the T-shaped locking block 4, and the splicing slot 6 are interlocked. Specifically, the modular cofferdam panels 1 are spliced ​​in pairs. During the process, the splicing block 3 and T-shaped locking block 4 of one module cofferdam 1 are slidably installed into the splicing slot 6 of another module cofferdam 1, thereby realizing the rapid splicing of the module cofferdam 1. The shape of the splicing slot 6 can extend the leakage path. The interlocking setting of the splicing block 3, T-shaped locking block 4 and splicing slot 6 makes it difficult for the spliced ​​single module cofferdam 1 to move left or right or back and forth, and the connection is relatively stable. During the connection process, the rubber sealing layer 7 and water-swellable waterstop 8 bonded to the splicing block 3, T-shaped locking block 4 and splicing slot 6 are tightly attached to form an initial sealing structure. The water-swellable waterstop 8 expands when exposed to water to fully compensate for the joint gap, further playing a role in preventing leakage.

[0019] like Figure 2 and Figure 5 As shown, multiple reinforcing strips 9 are fixed at equal intervals on one side of the connecting frame 5. The front side of the reinforcing strips 9 has an arc-shaped protrusion structure, and the reinforcing strips 9 are located on the front side of the modular cofferdam plate 1 and are in contact with the surface of the modular cofferdam plate 1. During splicing, the ends of the reinforcing strips 9, which are evenly distributed on one side of the connecting frame 5 of the modular cofferdam plate 1, are in contact with the connecting frame 5 of another modular cofferdam plate 1, thereby limiting and securing the connecting frame 5 and providing effective support to prevent deformation of the connecting frame 5. The arc-shaped protrusion structure on the front side of the reinforcing strips 9 can play a certain role in impact resistance and provide a certain degree of protection for the modular cofferdam plate 1.

[0020] like Figure 1 and Figure 4 As shown, a storage frame 10 is fixed to the lower rear side of the modular cofferdam plate 1, and an auxiliary support assembly 11 is installed inside the storage frame 10. The auxiliary support assembly 11 includes a damping shaft 1101, a collar 1102, and a locking bolt 1103. The damping shaft 1101 is rotatably installed on the upper side inside the storage frame 10, and the collar 1102 is slidably sleeved on the outer side of the damping shaft 1101. The locking bolt 1103 passes through the collar 1102. The auxiliary support assembly 11 also includes a telescopic rod 1104 and an anchor nail 1105. The telescopic rod 1104 is installed on the lower side of the collar 1102, and the bottom of the telescopic rod 1104 is fixed with an anchor. Nail 1105; Storage frame 10 is used to store auxiliary support components 11. The sliding of collar 1102 on the outside of damping shaft 1101 facilitates the adjustment of the position of telescopic rod 1104 and anchor nail 1105, making it convenient to use; Damping shaft 1101 has a certain damping friction and is not easy to rotate under non-strong force conditions. The rotation of damping shaft 1101 facilitates the rotation of telescopic rod 1104 and anchor nail 1105. The length of telescopic rod 1104 is adjustable, so that anchor nail 1105 can be embedded in the riverbed mud or the laid concrete base, thereby supporting the modular cofferdam plate 1 to improve its stability.

[0021] In summary, as Figures 1-5 As shown, when the modular cofferdam panels 1 are spliced ​​in pairs, the splicing block 3 and T-shaped clip 4 of one modular cofferdam panel 1 are slidably installed into the splicing slot 6 of the other modular cofferdam panel 1, realizing the rapid splicing of the modular cofferdam panels 1. The shape of the splicing slot 6 can extend the leakage path. The interlocking setting of the splicing block 3, T-shaped clip 4 and splicing slot 6 makes it difficult for the spliced ​​single modular cofferdam panel 1 to move left or right or back and forth, and the connection is relatively stable. After the splicing block 3, T-shaped clip 4 and the rubber sealing layer 7 and water-swellable waterstop 8 inside the splicing slot 6 are connected, they are tightly attached to form an initial sealing structure. At the same time, the water-swellable waterstop 8 can expand when exposed to water to fully compensate for the joint gap, and further play a role in preventing leakage. Furthermore, during splicing, the ends of the reinforcing strips 9, which are evenly distributed on one side of the connecting frame 5 of the modular cofferdam plate 1, can fit against the connecting frame 5 of another modular cofferdam plate 1, thereby limiting and securing the connecting frame 5 and providing effective support to prevent deformation of the connecting frame 5. The front side of the reinforcing strip 9 has an arc-shaped protrusion structure that can play an impact-resistant role, thereby providing a certain degree of protection for the modular cofferdam plate 1. The modular cofferdam plate 1 is a composite steel plate with an internally filled polyurethane insulation and waterproof layer. The wave-shaped reinforcing rear plate 2 is fixed to the rear side of the modular cofferdam plate 1 to improve its structural strength. During use, the damping shaft 1101 can also drive the telescopic rod 1104 and the anchor nail 1105 to rotate. The length of the telescopic rod 1104 is adjustable, so that the anchor nail 1105 can be embedded in the riverbed mud or the uncured concrete base, thereby supporting the modular cofferdam plate 1 and improving its stability. This completes the use process of the quick connection structure of the anti-seepage cofferdam for underwater construction.
