Further, as shown in fig. 3, in order to compensate for the loss of strength of the side plate 31 caused by the insertion holes 311 formed in the side plate 31, a thickened portion 312 is formed on the side plate 31 corresponding to each insertion hole 311, and the insertion holes 311 are formed on the thickened portion 312 corresponding thereto. The thickness of the side plate 31 at the inserting hole 311 is thickened by the thickened portion 312, so that the strength of the side plate 31 at the inserting hole 311 is improved, the side plate 31 is not easy to damage when being subjected to the shearing force of the water diversion structure 4, meanwhile, the width of the inserting hole 311 along the thickness direction of the side plate 31 can be widened by the thickened portion 312, the contact area of the water diversion structure 4 and the side plate 31 is enlarged, and stable connection of the water diversion structure 4 and the side plate 31 is facilitated.

In this embodiment, the thickened portion 312 is a protruding structure on the surface of the side plate 31, the thickened portion 312 and the side plate 31 are integrally cast and formed, and the plugging hole 311 is directly formed through a preformed hole on the mold during casting, so that the construction speed is effectively improved, the construction cost is saved, and the strength of the side plate 31 is ensured in an integrally cast and formed mode. Further, in order to save material cost, the cross section of the thickened portion 312 is trapezoidal, the small diameter end of the trapezoid is close to the opening of the plugging hole 311, and the large diameter end is connected to the side wall of the side plate 31, however, in other embodiments, the cross section of the thickened portion 312 may be rectangular or fan-shaped, which is not limited to the scheme provided in this embodiment.

Further, as shown in fig. 1 and 4, the water diversion structure 4 includes a water diversion plate 41 and a limiting plate 42, the limiting plate 42 is connected to one end of the water diversion plate 41, the other end of the water diversion plate 41 extends into the rapid trough 3 through the insertion hole 311, and the limiting plate 42 is abutted against the outer side wall of the side plate 31. The position of the water diversion plate 41 on the side plate 31 is determined by the arrangement of the limiting plate 42, and the water diversion structure 4 is fixed.

Because the spliced eye 311 is the horizontality setting, and diversion board 41 peg graft behind spliced eye 311 with curb plate 31 set up perpendicularly, therefore, preferably, limiting plate 42 sets up perpendicularly with diversion board 41 to make limiting plate 42 can laminate completely with the lateral wall of curb plate 31, thereby further increased the area of contact of diversion structure 4 and curb plate 31, strengthened the stability that diversion structure 4 and curb plate 31 are connected.

In the present embodiment, the thickened portion 312 protrudes from the inner side wall of the side plate 31, so that the limiting plate 42 is convenient to abut against the outer side wall of the side plate 31. Of course, in other embodiments, the thickened portion 312 may also protrude from the outer side wall of the side plate 31, and the limiting plate 42 abuts against the thickened portion 312, or both the inner side wall and the outer side wall of the side plate 31 are provided with the thickened portion 312.

Because the rapid trough 3 is obliquely arranged, water flow in the rapid trough 3 can flow along the surface of the bottom plate 32, one side of the water diversion part 411 is abutted against the bottom plate 32, so that the water diversion and absorption effects of the water diversion part 411 are better, and the phenomenon that part of water flow in the rapid trough 3 flows away from the gap between the water diversion part 411 and the bottom plate 32 is avoided, so that the impact force of the part of water flow cannot be slowed down. The setting of backstop portion 412 can prevent that the water on the diversion portion 411 from deviating from the one side of bottom plate 32 from flowing out, and the front and back both sides of diversion portion 411 are stopped by backstop portion 412 and bottom plate 32 respectively, and wherein one end is stopped by curb plate 31 rather than being connected, therefore the water on diversion portion 411 can only flow towards the direction rather than having spaced curb plate 31 to on diversion portion 411 of next diversion structure 4, realizes the layer upon layer of water flow of a plurality of diversion structures 4 to the torrent groove 3.

Correspondingly, since the diversion plate 41 in the present embodiment extends into the rapid trough 3 from the outside of the rapid trough 3 through the insertion hole 311, the section of the insertion hole 311 should be consistent with the section of the diversion plate 41, and meanwhile, as shown in fig. 3, in order to enable the diversion portion 411 to abut against the bottom plate 32, one end of the insertion hole 311 close to the bottom plate 32 needs to extend to the surface of the bottom plate 32.

Further, the upper surface of the water diversion portion 411 gradually decreases in height from the end near the limiting plate 42 to the end away from the limiting plate 42, and gradually decreases in height from the end near the stopper portion 412 to the end away from the stopper portion 412. So set up, can be with the water on the diversion portion 411 one end that deviates from limiting plate 42 and the one end drainage that deviates from stop portion 412, deviate from limiting plate 42 and be close to the one corner drainage of bottom plate 32 towards diversion portion 411 promptly to make rivers can follow the slope of bottom plate 32 downwards drainage to the diversion portion 411 of next diversion structure 4 on, be favorable to reducing the impact force of rivers to diversion structure 4, prevent diversion structure 4 by the punching out.

Further, the upper surface of the water diversion portion 411 is provided with a plurality of diversion grooves 4111 sequentially arranged at intervals, and the diversion grooves 4111 extend from one end close to the limiting plate 42 to one end away from the limiting plate 42. The plurality of diversion grooves 4111 enable the upper surface of the diversion portion 411 to be in concave-convex relief, so that a worker can play a role in skid resistance when walking on the diversion portion 411, the diversion grooves 4111 extend from one end close to the limiting plate 42 to one end deviating from the limiting plate 42, and the diversion grooves are matched with the gradual decrease of the height of the upper surface of the diversion portion 411 from one end close to the limiting plate 42 to one end deviating from the limiting plate 42, so that water on the diversion portion 411 is better drained towards the next diversion portion 411.

Further, the distance between the diversion groove 4111 and the bottom plate 32 gradually decreases from the end close to the limiting plate 42 to the end deviating from the limiting plate 42, and this structure is matched with the gradual decrease of the height of the upper surface of the diversion portion 411 from the end close to the stop portion 412 to the end deviating from the stop portion 412, so as to better divert the water on the diversion portion 411 toward the corner deviating from the limiting plate 42 and close to the bottom plate 32, further promote the water flow of the diversion portion 411 to be led to the diversion portion 411 of the next diversion structure 4 along the bottom plate 32, and reduce the impact force of the water flowing from the previous diversion structure 4 to the next diversion structure 4.

In this embodiment, the soil fixing plate 43 and the water diversion plate 41 are located on the same horizontal plane, the soil fixing plate 43 is also vertically arranged with the limiting plate 42, and the water diversion structure 4 is formed by combining the water diversion plate 41, the limiting plate 42 and the soil fixing plate 43, so that the water diversion structure 4 is convenient to process.

Due to the arrangement of the soil fixing plate 43, when the water diversion structure 4 is spliced on the side plate 31, the soil fixing plate 43 can extend out of the rapid trough 3 from the inner side of the rapid trough 3 through the splicing holes 311, the limiting plate 42 is abutted against the inner side wall of the side plate 31, and at this time, the section of the splicing holes 311 is consistent with the section of the soil fixing plate 43.

Further, as shown in fig. 2, since the bottom plate 32 of the rapid trough 3 is obliquely arranged along the slope of the side slope 200, in order to more stably fix the position of the rapid trough 3, the rapid trough 3 is prevented from sliding along the side slope 200, a plurality of anti-slip steps 321 are convexly arranged on the back surface of the bottom plate 32 at intervals in sequence along the extending direction of the rapid trough 3, and the anti-slip steps 321 are embedded in the soil body of the side slope 200. Preferably, the bottom surface of the anti-slip step 321 is disposed horizontally.
