[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-3 As shown, a highway bridge construction cofferdam device includes four waterproof boards 1, each of which is provided with a stabilizing structure 2 inside, the stabilizing structure 2 includes a stabilizing groove 8, three plug legs 4 are fixedly installed on the bottom of the waterproof board 1, a clamping block 5 is fixedly installed on one side of the waterproof board 1, and a fixing block 6 is fixedly installed on the other side of the waterproof board 1, a clamping groove 7 is provided inside the fixing block 6 through the rear part, the stabilizing groove 8 is provided inside the waterproof board 1 and through the top of the waterproof board 1, and five groups of stabilizing rods 9 are fixedly installed inside the stabilizing groove 8 inside the waterproof board 1.

[0023] In this embodiment, a group of stabilizing rods 9 is composed of two stabilizing rods 9 cross-fixed, and four waterproof boards 1 are distributed in a square. Since the triangle has stability, the two stabilizing rods 9 cross-fixed to each other can improve the impact resistance of the waterproof board 1.

[0024] In this embodiment, the block 5 is adaptively matched with the slot 7, and the block 5 is in an "L" shape. After the two waterproof boards 1 are spliced ​​by the block 5 and the slot 7, since the block 5 is in an "L" shape, when the two waterproof boards 1 are impacted by waves, the block 5 and the slot 7 are more firmly connected.

[0025] In this embodiment, the front of the four waterproof boards 1 are all provided with a reinforcement structure 3, and the reinforcement structure 3 includes a reinforcement plate 10, which is fixedly installed at the front bottom position of the waterproof board 1. The front of the waterproof board 1 is fixedly installed with a force unloading plate 12. After the force unloading plate 12 is impacted by water waves, the water waves will be diverted through two inclined surfaces, thereby achieving the purpose of unloading, so that the impact resistance of the waterproof board 1 is further improved, and the diverted water waves will be diverted to the positions of the slot 7 and the block 5, thereby further making the card connection between the block 5 and the slot 7 more firmly.

[0026] In this embodiment, the bottom of the reinforcing plate 10 passes through the force unloading plate 12 , and the force unloading plate 12 is provided with two mutually symmetrical inclined surfaces.

[0027] In this embodiment, the interior of the reinforcement plate 10 is hollow, and the interior of the reinforcement plate 10 is connected to the stabilizing groove 8. The reinforcement plate 10 is arranged in an inclined state. The rear part of the reinforcement plate 10 is located inside the stabilizing groove 8 and is fixedly installed with a baffle 11. The rear part of the baffle 11 is fixedly connected to the rear part of the stabilizing groove 8. When concrete is injected into the interior of the waterproof board 1 through the stabilizing groove 8, part of the concrete will be injected into the interior of the reinforcement plate 10 through the baffle 11, so that the reinforcement plate 10 can support its waterproof board 1, thereby making the installation of the waterproof board 1 more stable.

[0028] It should be noted that the utility model is a cofferdam device for highway bridge construction. When in use, the waterproof board 1 is installed into a river or ocean along three plug legs 4 through an external lifting device, and then the remaining three waterproof boards 1 are installed in sequence, and the four waterproof boards 1 are spliced ​​in sequence in a square shape through the engagement of the clamping block 5 and the clamping slot 7, and then concrete is injected into the interior of the waterproof board 1 through the stabilizing groove 8, so that the weight of the waterproof board 1 is increased, and the installation is completed at this time;

[0029] Since the triangle has stability, the two mutually cross-fixed stabilizing rods 9 can improve the impact resistance of the waterproof board 1. Since the clamping block 5 is in an "L" shape, when the two waterproof boards 1 are impacted by waves, the clamping block 5 and the clamping slot 7 are more firmly connected.

[0030] After the force unloading plate 12 is impacted by the waves, the waves will be diverted through the two inclined surfaces, thereby achieving the purpose of unloading, so that the impact resistance of the waterproof plate 1 is further improved, and the diverted waves will be diverted to the positions of the card slot 7 and the card block 5, thereby further making the card block 5 and the card slot 7 more firmly connected;

[0031] When concrete is injected into the interior of the waterproof board 1 through the stabilizing groove 8, part of the concrete will be injected into the interior of the reinforcing plate 10 through the baffle 11, so that the reinforcing plate 10 can support its waterproof board 1, thereby making the installation of the waterproof board 1 more stable.
