Method for promoting siltation and sand consolidation on beach by utilizing natural energy
TLDR
In this paper, a method for promoting siltation and sand consolidation on a beach by utilizing natural energy, and belongs to a coastal reclamation technology in coastal engineering, is described.Abstract:
The invention discloses a method for promoting siltation and sand consolidation on a beach by utilizing natural energy, and belongs to a coastal reclamation technology in coastal engineering. The method comprises the following steps: investigation, geological survey, design planning, damming and sluice-building, siltation promotion and water drainage, and mud conveying and sand consolidation. The method is characterized in that sediment deposition is promoted by utilizing natural energy of tides according to the principle of adjusting measures to local conditions and making the best use of the circumstances. Clearance electric energy of a plurality of pieces of power generating equipment is collected to establish a natural energy power station for supplying power to sediment conveying equipment. Sand consolidation is carried out by adopting methods of filling geotextile bags, mixing with a dehydrating hardening agent and biologically hardening. The method has the characteristics of adopting a multi-point formation process, being gradually expanded, being green and low-carbon, being energy-saving and environmentally-friendly, and being remarkable in benefit. Moreover, materials are saved, energy consumption is reduced and labor power is saved, so that the method is green and environmentally-friendly, and is safe and reliable. The method is used for dissipating waves, promoting siltation, consolidating sand and protecting a slope, so that irregular accumulation of sediments is improved, beach elevation is improved, a large number of land resources are obtained, and ecological balance is kept.read more
