Conventional water-blocking cofferdams are designed for a flood standard of once every 10 years. If a flood exceeds this standard, the cofferdam will become ineffective, and the tunnel project below will face the safety risk of flood backflow. This requires a device capable of intercepting floods exceeding this standard. This device needs to be able to resist flood erosion and prevent flood backflow. It needs to be strong and effective, easy to install, and long-lasting. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.
[0029] Combine Figures 1 to 5 As shown, this embodiment is a flood barrier device for hydraulic tunnels, comprising a gate slot structure 1, a steel gate structure 3, a support assembly, and an anti-seepage assembly. The gate slot structures 1 are located on both sides of the tunnel. Grooved embedded parts 2 are located on the opposing sidewalls of the two gate slot structures 1. A steel gate structure 3 is located between the two gate slot structures 1. The two ends of the steel gate structure 3 are vertically plugged into the corresponding embedded parts 2. The gate slot structure 1 and the steel gate structure 3 work together to form a flood barrier. Support assemblies are located on the walls of the steel gate structure 3 to provide support for the steel gate structure 3. An anti-seepage assembly is located on the waterfront side of the steel gate structure 3 to prevent floodwater from penetrating into the tunnel.
[0030] In some embodiments, the steel gate structure 3 includes a steel plate 31 and a channel steel rib 32. A plurality of channel steel ribs 32 are welded horizontally and vertically on the steel plate 31. Specifically, the steel plate 31 is a 20 mm thick plate, and the channel steel rib 32 is 8# channel steel.
[0031] Furthermore, a pair of lifting rings are welded on the top of the steel gate structure 3. Before the flood season warning, the lifting rings can facilitate the installation of the steel gate structure 3 in the gate slot structure 1 by a crane or a hoist.
[0032] Furthermore, the gate slot structure 1 is cast by reinforced concrete. In the early stage of tunnel support, the tunnel side walls are welded and fixed to the embedded parts 2 in the gate slot structure 1 by reinforcing anchor rods to form a whole.
[0033] In some embodiments, as Figure 3 and Figure 4As shown, the support assembly includes door latches 4 and door latches 5. At least two sets of door latches 4 are welded to the bottom wall of the steel gate structure 3. The tunnel floor has pre-reserved sockets corresponding to the door latches 4. The door latches 5 are inserted into the sockets to support the steel gate structure 3. Specifically, the door latches 5 are made of 48mm diameter steel pipes. The sockets on the tunnel floor are closed during tunnel construction and opened during flood season to facilitate the insertion of the steel pipes.
[0034] In some embodiments, as Figure 2 and Figure 5 As shown, the anti-seepage component includes a rainproof cloth 6 and a sandbag 7. The water-facing side wall of the steel gate structure 3 is covered with a rainproof cloth 6. The rainproof cloth 6 is compacted by multiple sandbags 7. The rainproof cloth 6 can improve the overall anti-seepage ability of the structure, and the sandbags 7 can increase the overall anti-scouring ability of the structure.
[0035] The implementation principle of a flood blocking device for a hydraulic tunnel is as follows:
[0036] The steel gate structure 3 is plugged into the gate slot structures 1 on both sides, and the gate slot structure 1 is connected to the tunnel side wall, so that the overall rigidity and stability of the device are effectively guaranteed. By plugging the door pin 5 into the door pin buckle 4, and partially inserting the door pin 5 into the hole reserved in the tunnel floor, a stable connection is formed between the device and the tunnel floor, thereby improving the shear resistance of the structure and reducing the bending deformation of the steel gate structure 3. By placing sandbags 7 on the periphery of the rainproof cloth 6, the sandbags 7 compact the rainproof cloth 6, and the sandbags 7 can reduce flood erosion, so that the rainproof cloth 6 and the sandbags 7 form a double protection, which improves the anti-seepage and anti-erosion capabilities of the overall structure. The overall device is easy and quick to install and can be used for emergency disposal work in sudden situations.
[0037] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
