The positional relationships depicted in the drawings are for illustrative purposes only and are not to be construed as limiting the present patent.
The present invention will be further described with reference to the accompanying fig. 1 and the examples, but the invention is not limited thereto.
Referring to fig. 1, the present embodiment provides an ecological restoration structure suitable for muddy coastal zones, which includes an ecological submerged dam, a landscape architectural structure, and saline alkali tolerant plants 6.
The ecological submerged dam comprises an ecological submerged dam fixing beach 7 arranged on the water facing side of a coastal zone shore base, a pine pile 1 embedded in the water facing side of the ecological submerged dam fixing beach 7, and a geotextile tube bag submerged dam 2 arranged close to the water back side of the pine pile 1.
Further, the pine pile 1 is used for supporting the earthwork tube bag submerged dam 2 and has the function of weakening the elutriation effect of waves on the inner side, the tip diameter of the pine pile 1 is 12cm, the length of the pine pile is 6m, fresh pine is adopted for processing, the pile body is straight, and no crack exists.
Further, the geotextile tube bag submerged dam 2 is formed by firstly laying a geotextile tube bag and then filling beach sludge.
