Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0023] like Figure 1 As shown, a restricted waterway wave-breaking ecological revetment structure comprises an ecological revetment slope 1 and a water-facing wave-breaking structure 2 constructed on the ecological revetment slope 1 close to the waterway. Aquatic plants 3 are arranged on the side of the ecological revetment slope 1 close to the water-facing wave-breaking structure 2 for easy growth. A slope is arranged on the side of the ecological revetment slope 1 away from the water-facing wave-breaking structure 2. Slope-fixing turf 4 is arranged on the slope for fixing the slope and resisting soil erosion. The structure has a certain effect in eliminating the high waves caused by ships in the restricted waterway, which not only weakens the impact of waves on the revetment and maintains the stability of the waterway revetment, but also provides a good living space for aquatic plants and animals, further improving the ecology of the waterway.

[0024] The water-front wave-breaking structure 2 includes a stepped mortar-stone retaining wall 201 connected to the ecological revetment slope 1. The stepped mortar-stone retaining wall 201 is provided with a precast concrete retaining wall 202 on the side close to the waterway. The stepped mortar-stone retaining wall 201 is provided with a fish nest brick group 203, wave-breaking stones 205 and a sliding arc retaining wall 204 in sequence from the steps close to the side of the waterway upward, so as to form a multi-level wave-breaking structure and reduce the scouring of the revetment.

[0025] like Figure 4 As shown, a buffer mechanism is provided on the stepped mortar-stone retaining wall 201, and the buffer mechanism can mitigate the impact of waves on the arc-shaped retaining wall 204. The buffer mechanism includes a mounting cavity 9 provided in the back side wall of the stepped mortar-stone retaining wall 201, a support rod 10 is fixedly connected inside the mounting cavity 9, two sliding sleeves 11 are symmetrically sleeved at both ends of the support rod 10, and second springs 12 are fixedly connected between the two sliding sleeves 11 and the two side walls of the mounting cavity 9, and the two second springs 12 are sleeved on the support rod 10.

[0026] One side of the two sliding sleeves 11 is hinged to one end of two symmetrically arranged rocker arms 13, the back side wall of the stepped mortar-masonry retaining wall 201 is provided with a sliding opening 14 connected to the installation cavity 9, the rear side wall of the arc-shaped retaining wall 204 is fixedly connected with a fixed block 15, the other ends of the two rocker arms 13 extend out of the sliding opening 14 and are respectively hinged to the two ends of the fixed block 15, the two rocker arms 13 are both arranged through the sliding opening 14, the inner wall of the sliding opening 14 is frictionally connected to the side walls of the rocker arms 13, so that the rocker arms 13 swing more stably.

[0027] When the arc-shaped retaining wall 204 is impacted by water waves, it will be displaced, which in turn pushes the two swing arms 13 to swing, and can push the two sliding sleeves 11 to move in opposite directions on the support rod 10. At this time, the two second springs 12 are squeezed and contracted to generate elastic force, which can buffer and weaken the impact force on the arc-shaped retaining wall 204, play a buffering and protective role, and extend the service life of the arc-shaped retaining wall 204.

[0028] As a preferred embodiment of the utility model, a slide groove 5 is provided on the stepped mortar-stone retaining wall 201 located below the arc-shaped retaining wall 204, and a slider 6 is fixedly connected to the bottom of the arc-shaped retaining wall 204. The slider 6 can slide in the slide groove 5. A telescopic rod 7 is provided in the slide groove 5. The two ends of the telescopic rod 7 are respectively fixed to the slider 6 and the side wall of the slide groove 5, and a first spring 8 is sleeved on the telescopic rod 7.

[0029] When the arc-shaped retaining wall 204 is impacted by water waves, it will be displaced, which can push the slider 6 to slide in the slide groove 5. At this time, the telescopic rod 7 and the first spring 8 are squeezed and contracted to generate elastic force, which can buffer and weaken the impact force on the arc-shaped retaining wall 204, thereby playing a double buffering role.

[0030] like Figure 3 and Figure 4 As shown, the front side wall of the arc-shaped retaining wall 204 is provided with a plurality of reinforcing ribs 2041, so that the structure strength of the arc-shaped retaining wall 204 is higher. Meanwhile, the reinforcing ribs 2041 can cut the waves into several parts, further weakening the impact force.

[0031] As a preferred embodiment of the present invention, the fish nest brick group 203 is composed of fish nest bricks, and the fish nest brick group 203 is arranged in two or more layers on the stepped mortar-stone retaining wall 201, such as Figure 2 As shown, the fish nest bricks are constructed of concrete, and the fish nest brick structure is divided into two layers, the upper layer is a pre-filled soil layer for the growth of aquatic plants; the two sides of the upper layer are porous partitions, which are conducive to the material exchange between the soil and the water body and are more ecological; the lower layer is a hollow space, providing a habitat for fish.

[0032] like Figure 1 As shown, the top outer side of the precast concrete retaining wall 202 is convex outward. Since the precast concrete retaining wall 202 is a precast structure, the overall strength is relatively large and can withstand the greater impact of waves. The convex upper end can play the role of backflow and wave suppression.

[0033] As a preferred embodiment of the present invention, the precast concrete retaining wall 202 is provided with a plurality of perforations 206. The perforations 206 can absorb some of the impact energy of the waves and play a role in reducing noise, thereby greatly improving the service life of the precast concrete retaining wall 202.

[0034] The working principle of this utility model:

[0035] Firstly, by successively adding precast concrete retaining walls 202, fish nest brick groups 203, wave-breaking stones 205 and arc-shaped retaining walls 204, a multi-level wave-breaking structure is formed to reduce the scouring of the revetment. Aquatic plants 3 and slope-fixing turf 4 are successively added on the ecological revetment slope 1 to fix the slope and resist soil erosion. This structure has a certain effect in eliminating the high waves caused by ships in the restricted waterway. It not only weakens the impact of waves on the revetment and maintains the stability of the waterway revetment, but also provides a good living space for aquatic plants and animals, further improving the ecology of the waterway.

[0036] Secondly, when the arc-shaped retaining wall 204 is displaced by the impact of water waves, the slider 6 can be pushed to slide in the slide groove 5. At this time, the telescopic rod 7 and the first spring 8 are squeezed and contracted to generate elastic force, which plays a buffering role and weakens the impact force on the arc-shaped retaining wall 204; at the same time, the arc-shaped retaining wall 204 moves backward and pushes the two rocker arms 13 to swing, pushing the two sliding sleeves 11 to move in opposite directions on the support rod 10. At this time, the two second springs 12 are squeezed and contracted to generate elastic force, which plays a double buffering and protective role; in addition, due to the special structure of the arc-shaped retaining wall 204, it plays a certain guiding role on the waves, changes the impact direction of the waves, offsets part of the impact of the waves, and at the same time can extend the service life of the arc-shaped retaining wall 204.

[0037] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Those skilled in the art can still adjust the technical solutions recorded in the above embodiments, or replace some of the technical features by equivalents. Therefore, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalent technologies, the utility model is also intended to include these modifications and variations.
