[0002] Water rescue is a rescue project with strong suddenness, tight time, high technical requirements, high difficulty and high risk. Water rescue is a great test of the professional level of rescuers, so rescuers need to undergo simulated water rescue training before participating in the rescue. At present, rescuers usually use rapids waterways for simulated water rescue training. Rapids waterways are used to simulate complex water flow patterns and provide trainees with a practical training environment. Rapids waterways can reproduce a variety of complex flow patterns to meet specific training needs. In order to better simulate rapids and achieve better emergency rescue training, obstacles are needed to change the water flow.

[0003] Obstacles in existing rapids waterways are usually cast into one piece with the main waterway of the rapids waterway, which not only takes a long time to construct but is also difficult to adjust later and cannot simulate various rapids, making it difficult to conduct water rescue simulation training.

A vertically extending mounting hole is provided on the obstacle unit 23, and a receiving groove 21 for accommodating a nut 52 is provided on the top of the obstacle unit 23, and a clamp 7 is provided in each receiving groove 21.

[0049] The installation assembly includes a long screw 51 and a clamp 7. The bolt cap 53 at one end of the long screw 51 is located in the groove of the C-shaped steel pipe 4 to prevent the long screw 51 from detaching from the C-shaped steel pipe 4; the other end of the long screw 51 passes through the installation hole of the obstacle unit 23 and then extends into the receiving groove 21 at the upper part of the obstacle unit 23, and is fixed by a nut 52, which abuts against the obstacle unit 23. During installation, there is a gap (i.e., no contact) between the bolt cap 53 of the long screw 51 and the bolt cap 622 of the bolt 62 in the height direction of the C-shaped steel pipe 4, so that the long screw 51 can move along the length direction of the C-shaped steel pipe 4.

When the steel structure is arranged, the force transfer tube 3 (square steel pipe) is welded, and then the C-shaped steel pipe 4 is welded. The force transfer tube 3 and the C-shaped steel pipe 4 are both arranged horizontally and perpendicular to each other. After that, concrete is poured so that the upper surface of the C-shaped steel pipe 4 is flush with the upper surface of the concrete. The size of the force transfer tube 3 can be 15mm*30mm*6000mm. The height of the force transfer layer can be 15mm, and the width can be 30mm. Of course, 50mm wide and 6000mm long can also be selected as needed.

The barrier module 2 can be made of plastic PVC and processed into a finished product in the factory, and then assembled after being transported to the construction site. The barrier module 2 can be designed into a three-dimensional structure of different heights, shapes, and volumes according to design requirements.
