[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0032] See Figure 1 and Figure 2 The diagram shows an ecological transformation structure for the top of a seawall, including a road surface structure 100, a wave wall 200, a green belt 300, a shoulder 400, and a water storage device 500.

[0033] The road surface structure 100 is built on the top of the embankment. The road surface structure 100 comprises an upper water-permeable structure 110 and a lower water-impermeable structure 120 arranged in a stack from top to bottom, which not only ensures that the road surface is supplied with water when it rains, but also prevents rainwater from penetrating into the soil layer of the embankment. In addition, the upper surface of the road surface structure 100 is inclined from the road center to both sides, so that the water on the road surface structure 100 is discharged to both sides, avoiding the accumulation of rainwater on the road surface structure 100 and accelerating the drainage of rainwater.

[0034] The wave protection wall 200 is built on the top of the embankment and located outside the road surface structure 100.

[0035] The wave protection wall 200 has an L-shaped structure, which comprises a wave protection bottom plate 210 and a wave protection wall body 220 built on the wave protection bottom plate 210. The wave protection bottom plate 210 adopts a reinforced concrete structure, and the wave protection wall body 220 adopts a reinforced concrete structure or a rubble masonry structure, which mainly plays a role in blocking waves and embankment soil.

[0036] A plurality of drainage short pipes 230 penetrating through the wave protection wall body 210 are arranged in the embankment axis direction at intervals in the lower part of the wave protection wall body 210. The drainage short pipes 230 are arranged in an inclined manner, i.e., high inside and low outside. The distance between adjacent two drainage short pipes 230 is 1.5m-4m. The drainage short pipes 230 adopt PVC pipes or other pipe materials. The hole top elevation of the drainage short pipes 230, i.e., the water inlet end of the drainage short pipes 230, is flush with the top of the water collecting layer 330 of the green belt 300, so that the excess rainwater in the water collecting layer 330 is discharged, and the plants in the green belt are not flooded.

[0037] The green belt 300 is built on the inner side of the wave protection wall 200. Specifically, the green belt 300 is built on the wave protection bottom plate 210 and located between the wave protection wall body 220 and the road surface structure 100. The green belt 300 comprises a planting soil layer 310, a geotextile layer 320 and a water collecting layer 330 arranged in a stack from top to bottom. The green plants 340 are planted on the planting soil layer 310.

[0038] In order to make the road surface rainwater seep into the water collecting layer 330 smoothly, a water-permeable body 350 is arranged on the geotextile layer 320 between the planting soil layer 310 and the road shoulder 400. The width of the water-permeable body 350 is 0.1m-0.2m. The water-permeable body 350 comprises a small gravel layer, a coarse sand layer and a fine sand layer arranged in a stack from top to bottom. The water-permeable body 350 ensures that the road surface rainwater seeps into the water collecting layer 330 smoothly, and the soil body of the water-permeable body 350 does not flow into the water collecting layer 330.

[0039] The water collecting layer 330 is filled with a material with a large porosity, such as single-graded gravel, and can store a certain amount of rainwater to provide water for the green plants 340 on the green belt 300 through capillary action. In addition, the geotextile layer 320 is folded downward at one side 321 close to the wave protection wall body 220 and extends to between the water collecting layer 330 and the wave protection wall body 220, so as to separate the water collecting layer 330 from the drainage short pipe 230 to prevent soil loss behind the wall.

[0040] The shoulder 400 is arranged on the wave protection bottom plate 210 and between the pavement structure 100 and the green belt 300, and the shoulder 400 and the wave protection bottom plate 210 are integrally cast in situ, or the shoulder 400 is precast and then arranged on the wave protection bottom plate 210. A plurality of drainage grooves 410 are arranged on the top surface of the shoulder 400 and spaced apart along the embankment axis direction, so that the top surface of the shoulder 400 is arranged in a staggered zigzag shape, so that the pavement rainwater seeps into the water collecting layer 330 from the upper part of the drainage groove 410 (low shoulder) through the water permeable body 350, and the high shoulder 420 prevents vehicles from entering the green belt 300, as shown in Figure 3

[0041] The water storage device 500 is located below the pavement structure 100 and close to the shoulder 400, and is used for storing embankment rainwater and supplying water for the green belt 300. The water storage device 500 comprises a water storage pipe 510 and a plurality of thin connecting pipes 520, the water storage pipe 510 is arranged on the wave protection bottom plate 210, extends along the embankment axis direction and is located below the pavement structure 100 and inside the shoulder 400, and the plurality of thin connecting pipes 520 are arranged in a spaced apart manner along the embankment axis direction, one end of each thin connecting pipe 520 is in communication with the water storage pipe 510, and the other end of each thin connecting pipe 520 is in communication with the water collecting layer 330 after penetrating through the shoulder 400. When it rains, the excess rainwater in the water collecting layer 330 flows into the water storage pipe 510 through the thin connecting pipe 520 for storage, and when the water in the water collecting layer 330 is lost, the water stored in the water storage pipe 510 flows into the water collecting layer 330 through the thin connecting pipe 520 under the action of gravity to compensate.

[0042] The construction method of the ecological reconstruction structure of the seawall crest of the utility model comprises the following steps:

[0043] Step S1, the original crest wave protection wall and pavement structure of the seawall are removed;

[0044] Step S2, the wave protection wall 200 on the outside of the crest is poured according to the design requirements, and the drainage short pipe 230 is pre-buried in the wave protection wall 200;

[0045] Step S3, the water storage device 500 is buried at a position below the pavement structure 100 and close to the shoulder 400;

[0046] ​Step S4, a green belt 300 is built on the inner side of the wave protection wall 200, i.e. the water collecting layer 330, the geotextile layer 320, the water permeable body 350 and the planting soil layer 310 are sequentially laid, and the green plants 340 are planted on the planting soil layer 310;
