As shown in fig. 3-5, the guard assembly comprises: a number of support structures 9, a flow eliminating structure 7 and a reinforcement 10.
Wherein, a plurality of supporting structures 9 are arranged at intervals along the direction vertical to the lifting prevention of the river channel 1 and are inserted into the river bed 11. Specifically, the supporting structure 9 is buried in the river bed 11, and the buried depth is larger than the theoretical maximum scouring depth, so that the whole structure is prevented from collapsing after the foundation of the supporting structure 9 is hollowed out under the action of high flow velocity.
The tops of the several support structures 9 are the same in height, and the tops 84 of the support structures 9 are provided with mounting slots 81. As a preferred embodiment, the spacing between adjacent support structures 9 is in the range of 2-3 m. In the embodiment of the present utility model, the interval between the adjacent support structures 9 is set to 2.5m. The flow-canceling structure 7 is mounted into mounting slots 81 of several support structures 9. The flow eliminating structure 7 is provided with a plurality of interconnected rectangular steel reinforcement cages 8, and a plurality of rectangular holes 82 are formed in the surface of the steel reinforcement cage 9. The surface of the reinforcement cage 8 is coated with an anti-corrosion paint layer or other anti-corrosion measures, so that the service life of the reinforcement cage under the action of the saline water body is ensured.
An accommodating space is formed in the reinforcement cage 9, and a plurality of pebbles are arranged in the accommodating space. The plurality of reinforcement cages 8 are fixedly connected with each other through steel wires, and the connecting positions of the plurality of reinforcement cages 8 are positioned in the mounting groove 81 of the supporting structure 9. Preferably, the rectangular hole 82 of the reinforcement cage 8 has a side length of 8cm, and the pebble particle size is larger than 8cm, so that the pebble is prevented from being flushed out of the reinforcement cage 8 under the action of water flow. In addition, the pebbles have larger porosity and better flow eliminating effect.

Therefore, when the tide level is smaller than the bottom 83 of the current eliminating structure 7, water flow can freely pass through the current eliminating structure without being influenced by the reinforcement cage 8, and the current eliminating structure 7 is ensured not to influence the offshore ecological process. When the tide level is greater than the bottom 83 of the flow eliminating structure 7, the flow velocity affects the revetment, and the flow eliminating structure 7 can play an energy eliminating role.
When the tide level reaches the highest tide level, the flow velocity of water flow after energy dissipation by the flow dissipation structure 7 is reduced, and the erosion to the revetment is reduced. In addition, the porous structure of the flow eliminating structure 7 can provide a refuge place for aquatic animals.
As a preferred embodiment, the guard assembly is laid over the entire high-level inundation area 3 and part of the average-level inundation area 2 of the river channel 1. As shown in fig. 1 and 2, the cross section of an incoming river may generally include a river channel 1 between A-A, an average tidal level inundation area 2 between a-B, and a high tidal level inundation area 3 between B-C, with the tops 84 of the side dikes 4 being designed to be higher than the highest tidal level to prevent the tidal current from spreading across the dikes. The protection components are laid in the whole high-tide inundation area 3 and part of the average tide inundation area 2 of the river channel 1. The guard assembly extends from the dike feet 41 towards the river channel 1.
