A silt-promoting dam and a silt-promoting method for land reclamation

Abstract

The invention discloses a deposition promotion dyke and a deposition promotion method for reclaiming land from sea by building dykes. The deposition promotion dyke comprises a center dyke and expanding dykes, wherein the center dyke is arranged along a coastline; the center dyke and the coastline surround and form a center reservoir area; first one-way water gates are respectively arranged on two sides of the center dyke; the center reservoir area accommodates water through the first one-way water gates; one-way draining and generating equipment is arranged on the front side of the center dyke; water in the center reservoir area is drained to the outside through the one-way draining and generating equipment; the expanding dykes are arranged on two sides of the center dyke and are communicated with the center reservoir area through the first one-way water gates; the expanding dykes surround and form a deposition promotion area; second one-way water gates are arranged on the sides of the expanding dykes; the deposition promotion area accommodates water through the second one-way water gates. According to the setting, the deposition promotion dyke for reclaiming the land from the sea by building the dykes, which is provided by the invention, has the characteristics that the problem that silts are easily taken away by tide water can be solved and tidal energy can be effectively utilized for generating power.

Description

technical field [0001] The invention relates to the technical field of reclamation land reclamation, in particular to a silt-promoting embankment and a method for promoting silt reclamation. Background technique [0002] Sea reclamation is an effective way to solve the contradiction of land resource shortage in coastal areas. At present, with the decreasing high beach resources and increasing engineering experience, sea reclamation is gradually developing from tidal flat areas to shallow sea areas, and to large-scale development. Due to the relatively high sand content in half of the offshore seawater, the land reclamation in the shallow sea area is generally carried out with sedimentation promotion works first, and then reclamation. The effect of sediment deposition can be enhanced through the early implementation of the sedimentation promotion project, so as to reduce the investment of seawall projects, reduce the project risk, reduce the investment of dredging and reclama...
