Hard seawall face structure with active siltation promotion and mangrove forest habitat building functions

By introducing honeycomb hollow panels, porous matrix cups, and sloping wave walls into rigid seawall structures, a biological-structural anchoring system was formed, which solved the problem that rigid seawall structures could not simultaneously achieve engineering protection and ecological habitat creation under complex hydrodynamic conditions, and realized stable sediment deposition and mangrove growth.

AI Technical Summary

Technical Problem

Existing rigid seawall structures cannot meet the dual needs of engineering protection and ecological habitat creation. They cannot provide a stable environment for sediment deposition and mangrove growth under complex hydrodynamic conditions, resulting in vegetation being easily damaged or washed away by waves.

Method used

The rigid seawall structure, which has the functions of actively promoting sedimentation and creating mangrove habitat, is adopted. It includes wave walls, protective structure blocks and fences. By setting up honeycomb hollow panels, porous matrix cups and sloping wave walls, a biological-structure anchoring system is formed to promote sediment deposition and mangrove growth.

Benefits of technology

It enhanced the seawall's resistance to erosion, provided stable habitat conditions, promoted the natural succession of mangroves and the development of the ecosystem, and achieved an organic combination of engineering protection and ecological restoration.

Abstract

The invention belongs to the technical field of dike dam application, and particularly relates to a hard seawall surface structure with active siltation promotion and mangrove forest habitat building functions, which comprises a wave wall, a dike dam structure block and a fence, a plurality of mounting positions are arranged on the inclined face of the coastal side of the wave wall, dike dam structural blocks are arranged in the mounting positions, sludge matrixes are arranged in the dike dam structural blocks and in gaps between the mounting positions, and each dike dam structural block comprises an upper-layer honeycomb hollow plate, a combined structural frame and a base plate which are sequentially arranged from top to bottom. A lower-layer honeycomb hollow plate is arranged in the combined structure frame, and porous matrix cups are arranged on the lower-layer honeycomb hollow plate and used for guiding growth of root systems of mangrove forest plants. According to the hard seawall face structure with the active siltation promotion and mangrove forest habitat building functions, the anti-scouring capacity and the water and sediment regulation and control effect of a seawall under the complex hydrodynamic force condition are enhanced, sediment deposition is actively promoted, and stable and suitable habitat conditions are provided for tidal flat vegetation such as mangrove forests.
