Description

Technical Field

[0001] This utility model relates to the technical field of cofferdams, and in particular to a guiding device for the arc section of a "dumbbell-shaped" locking pile cofferdam. Background Technology

[0002] With the continuous development of bridge foundation construction technology, bridge engineering is increasingly moving towards deeper water and longer spans, leading to the emergence of various steel cofferdam structures in complex environments, among which the dumbbell-shaped cofferdam is one. A dumbbell-shaped cofferdam is a cofferdam structure that combines a dumbbell-shaped pier with steel plates. Dumbbell-shaped cofferdams offer advantages such as convenient construction and low cost.

[0003] Currently, dumbbell-shaped cofferdams are suitable for cofferdam construction in water conservancy, transportation, and other projects under various complex geological conditions. They can effectively control the deformation and displacement of the cofferdam, improving its stability and seismic resistance. Dumbbell-shaped cofferdams typically require a dumbbell-shaped frame formed by pipe piles; however, the arc segment of existing dumbbell-shaped cofferdams is difficult to control, easily leading to positional deviations.

[0004] To address this issue, we provide a guiding device for the arc segment of a "dumbbell-shaped" interlocking pile cofferdam to solve the problems mentioned above. Utility Model Content

[0025] The operation process of this embodiment is as follows: First, the inner support component 1 is assembled. Then, the two guide brackets 5 are welded to the inner support component 1.

Then, the support shaft 8 is welded to the surface of the inner V-shaped folding plate 3 and the outer V-shaped folding plate 4. Finally, the connecting shaft 9 is welded between each support shaft 8 to form a fence, thereby building a working space on the inner V-shaped folding plate 3 and the outer V-shaped folding plate 4.

[0026] In this embodiment, by welding the guide bracket 5 to the inner support assembly 1, and then welding the inner V-shaped folding plate 3 and the outer V-shaped folding plate 4 between the two guide brackets 5, the pile insertion slots 6 and connecting slots 7 on the inner V-shaped folding plate 3 and the outer V-shaped folding plate 4 are fixed, thereby ensuring the accuracy and stability of the subsequent pile insertion position, reducing the construction difficulty, improving the construction efficiency, and providing a good guarantee for the subsequent cofferdam closure.

[0027] For a specific embodiment two, please refer to Figure 1-5 Based on the first specific embodiment, the inner support component 1 includes two oppositely arranged C-arc segments 10; two parallel straight line segments 11 are connected between the two ends of the two C-arc segments 10; and parallel connecting segments 12 are connected between the two straight line segments 11.

[0028] Specifically, the connecting segment 12 is connected to the adjacent C-arc segment 10 and the straight segment 11 by a reinforcing segment 13; the C-arc segment 10, the straight segment 11, the connecting segment 12 and the reinforcing segment 13 all include several connecting blocks 14 that are welded and fixed to each other.

[0029] Furthermore, the two ends of the straight segment 11 are welded and fixed to the two C-arc segments 10 respectively through connecting blocks 14; the two ends of the connecting segment 12 are welded and fixed to the two straight segments 11 respectively through connecting blocks 14; the two ends of the reinforcing segment 13 are welded and fixed to the connecting segment 12, the C-arc segments 10, and the straight segments 11 respectively through connecting blocks 14.

[0030] The operation process of this embodiment is as follows: When building the inner support component 1, the connecting block 14 is used for welding and fixing to complete the construction of the C arc segment 10 and the straight segment 11, as well as the welding and fixing between the C arc segment 10 and the straight segment 11, forming the basic closed frame of the inner support component 1. Then, the connecting block 14 is used to build the connecting segment 12 and the reinforcing segment 13 to improve the connection strength of the inner support component 1.

[0031] For a specific embodiment three, please refer to Figure 1-5Based on specific embodiment one and specific embodiment two, a plurality of support piles 15 are uniformly fixed on the inner side of arc segment 10 and the inner side of straight segment 11; support plates 16 are welded and fixed between the support piles 15 and the corresponding arc segment 10 and straight segment 11; and reinforcing plates 17 are welded and fixed between the support plates 16 and the periphery of the support piles 15.

[0032] Specifically, the guide bracket 5 is welded and fixed to the support plate 16 on the C arc segment 10; a pipe pile 18 is slidably installed on the inner wall of the pile insertion groove 6; and a connector is welded between two adjacent pipe piles 18.

[0033] Furthermore, the connector includes an arc-shaped plate 19; the inner wall of the arc-shaped plate 19 is adapted to the circumferential side of the pipe pile 18; an L-shaped plate 20 is fixed to the circumferential side of the arc-shaped plate 19; the L-shaped plate 20 is fitted to the inner wall of the connecting groove 7.

[0034] The operation process of this embodiment is as follows: After the inner support component 1 and the guide component 2 are welded, piles are inserted. Multiple sets of support piles 15 are set inside the inner support component 1, and the support piles 15 are connected to the inner support component 1 with the support plate 16. Then, the pipe pile 18 is first inserted through the pile insertion groove 6. The pile insertion groove 6 positions and limits the pipe pile 18 to prevent the position of the pipe pile 18 from shifting and affecting the construction progress. Then, the connector is inserted through the connecting groove 7 so that the arc plate 19 is close to the periphery of the pipe pile 18. At the same time, the L-shaped plates 20 on the two adjacent connectors are close to each other. Finally, the pipe pile 18 is fixed on the inner support component 1. The pipe pile 18 is fixed. Then, the guide component 2 is removed and the next position is inserted until the guide component 2 has inserted all the pipe piles 18 in the C arc segment 10. For the straight segment 11, straight pile insertion can be performed. Finally, all the pipe piles 18 are connected by connectors to complete the cofferdam.

[0035] By using the guide component 2 of arc segment 10, the position of pipe pile 18 in arc segment 10 is ensured to be accurate, providing the correct direction for the insertion of pipe pile 18, reducing the offset and tilt of pipe pile 18 during construction, reducing construction difficulty, improving construction efficiency, and providing a good guarantee for the subsequent closure of cofferdam.
