[0047] The shape and structure of the tide wave separation seawall structure are described in detail as follows:

[0048] In the optional solution of the embodiment of the utility model, the tidal wave separation platform is gradually inclined upward from one side close to the dike toe intertidal zone 1 to the side far from the dike toe intertidal zone 1.

[0049] Specifically, the slope of the tidal wave separation platform is set to 1:10-1:20, and in the embodiment, the slope of the tidal wave separation platform is set to 1:10.

[0050] The tidal water and rainwater on the water-facing side of the seaside side are directly discharged into the outer sea through the inclined tidal wave separation platform.

[0051] In the optional solution of the embodiment of the utility model, the tidal wave separation platform is provided with a longitudinal drainage ditch and a transverse drainage ditch, and the longitudinal drainage ditch and the transverse drainage ditch are vertically arranged.

[0052] Specifically, the transverse drainage ditch extends along the length direction of the tidal wave separation platform, and the longitudinal drainage ditch extends along the width direction of the tidal wave separation platform. Preferably, the size of the longitudinal drainage ditch and the transverse drainage ditch is set to 0.5m*0.5m.

[0053] The longitudinal drainage ditch and the transverse drainage ditch realize rapid discharge of the accumulated water on the tidal wave separation platform.

[0054] In the optional solution of the embodiment of the utility model, three tidal wave separation platforms are arranged, which are a first tidal wave separation platform 31, a second tidal wave separation platform 32 and a third tidal wave separation platform 33, the first tidal wave separation platform 31, the second tidal wave separation platform 32 and the third tidal wave separation platform 33 are arranged in a stepped manner in sequence and gradually increase in height; the first tidal wave separation platform 31 and the second tidal wave separation platform 32 are both provided with a wave storage and drainage system 2.

Alternatively, the second tide wave separation platform 32 is arranged in multiple forms such as a landscape retaining wall, a cascade flower pool and a ladder sitting wall, so as to eliminate the height difference between the first tide wave separation platform 31 and the third tide wave separation platform 33 and enrich the waterfront landscape. The elevation of the first tide wave separation platform 31 is determined according to the daily high tide level arrangement result, and the elevation value should be close to the normal tide water level to meet the water-loving requirement, but should also be higher than the normal tide water level to avoid frequent flooding; preferably, the elevation of the first tide wave separation platform 31 is determined so that the first tide wave separation platform 31 is submerged by seawater not more than 2 times per month and can guarantee the water-loving requirement. The elevation of the third tide wave separation platform 33, that is, the landscape leisure greenway, should be at least higher than the design tide level plus a safety super-elevation of 0.5 m, and is determined in combination with the terrain condition of the location of the project. The platform has the requirements of pedestrian and leisure, and the width should be not less than 3 m, and the height difference between the second tide wave separation platform 32 and the third tide wave separation platform 33 is preferably between 0.5 m and 1 m.

When the tide wave separation platform is subjected to wave action, a large negative pressure is easily generated on the platform surface, which threatens the safety of the dike, and it is necessary to arrange a supporting retaining wall 4 on the water-facing surface of the platform, and the top surface of the platform is preferably made of an anti-impact facing material.

[0062] Specifically, the support retaining wall 4 can be designed into different shapes according to landscape modeling.

[0063] The support part 42 is used for supporting the facing part 43 and protecting the water-facing surface of the tidal wave separation platform, and the facing part 43 is used for reducing overtopping and wave picking.

[0064] In the optional scheme of the embodiment of the utility model, the seawall structure further comprises a blind ditch, the blind ditch is arranged below the tidal wave separation platform and extends to the dike toe intertidal zone 1.

[0065] Specifically, the blind ditch is arranged as a filter blind ditch. The blind ditch is buried below the tidal wave separation platform and extends to the dike toe intertidal zone 1 along the width direction of the tidal wave separation platform.

[0066] The blind ditch stores periodic overtopping water, prevents overtopping seawater superposition effect, and reduces the dike top elevation.

[0067] In the optional scheme of the embodiment of the utility model, the large-particle filler comprises riprap, and the water-permeable particle comprises block stone.

[0068] The large-particle filler comprises large-volume rigid materials such as riprap, and the dike toe intertidal zone 1 is fixed by the rigid materials.
