Description
Technical field
The utility model relates to the technical field of reclaiming fields from the sea, and relates in particular to a kind of short silt dykes and dams for reclaiming fields from the sea.
Background technology
Reclaiming fields from the sea is the effective way that solves coastal area land resources shortage contradiction, current along with day by day reducing of high beach resource and becoming increasingly abundant of engineering experience, reclaims fields from the sea and is developed and inclined to one side large scale development to neritic province domain by shoal area gradually.Because coastal seawater half sand content is higher, therefore reclaiming fields from the sea of neritic province domain generally first urged silt engineering, then encloses and fill out.Can strengthen Sediment Siltation effect by implementing in advance short silt engineering, reach and reduce embankment project investment, reduce engineering risk, reduce Dredger Filling Engineering investment, improve the object of project benefit.Therefore, the optimization of short silt scheme is one of key issue of the current engineering of reclaiming fields from the sea.
The short silt method of tradition: mostly adopt open short silt dam, as groynes, longitudinal dike and the combination of fourth longitudinal dike etc.But the silt that seawater carries, after near sedimentation short silt dike, as runs into high sea weather, wave can start silt again, and silt is taken away by tidewater again.Therefore the short silt cycle generally longer, and be easily subject to the impact of diastrous weather.
Therefore, how to solve the problem that short silt sand is easily taken away by tidewater, become those skilled in the art's important technological problems to be solved.
Utility model content
The utility model provides a kind of short silt dykes and dams for reclaiming fields from the sea, and it can effectively solve the problem that silt is easily taken away by tidewater, and can effectively utilize tide energy to generate electricity.
The short silt dykes and dams for reclaiming fields from the sea that the utility model provides, comprising:
The center dykes and dams that along the coastline arranges, described center dykes and dams and described coastline surround reservoir area, center, two avris of described center dykes and dams are equipped with the first unidirectional sluice, Na Shui is carried out by described the first unidirectional sluice in reservoir area, described center, and the front side of described center dykes and dams is provided with single slope drainage generating equipment, the water in reservoir area, described center drains into outside by described single slope drainage generating equipment;
Be arranged at two avris of described center dykes and dams and prolong dykes and dams by described the first unidirectional sluice with the expansion that reservoir area, described center is connected, described expansion is prolonged dykes and dams and is surrounded Cu Yu district, and the avris that dykes and dams are prolonged in described expansion is provided with the second unidirectional sluice, and described Cu Yu district carries out Na Shui by the second unidirectional sluice.
Preferably, the subregion dykes and dams that dykes and dams comprise that multiple along the coastlines distribute are prolonged in described expansion, and each subregion dykes and dams are equipped with described the second unidirectional sluice, two described subregion dykes and dams of arbitrary neighborhood are connected by described the second unidirectional sluice, and described in current direction when the direction of reservoir area, center described in the second unidirectional sluice in conducting state.
The short silt dykes and dams for reclaiming fields from the sea that the utility model provides, comprise: the center dykes and dams that along the coastline arranges, described center dykes and dams and described coastline surround reservoir area, center, two avris of described center dykes and dams are equipped with the first unidirectional sluice, Na Shui is carried out by described the first unidirectional sluice in reservoir area, described center, and the front side of described center dykes and dams is provided with single slope drainage generating equipment, the water in reservoir area, described center drains into outside by described single slope drainage generating equipment; Be arranged at two avris of described center dykes and dams and prolong dykes and dams by described the first unidirectional sluice with the expansion that reservoir area, described center is connected, described expansion is prolonged dykes and dams and is surrounded Cu Yu district, and the avris that dykes and dams are prolonged in described expansion is provided with the second unidirectional sluice, and described Cu Yu district carries out Na Shui by the second unidirectional sluice.
So arrange, the short silt dykes and dams that the utility model provides, comprise center dykes and dams, when the water level in center dykes and dams outsides is during higher than its inside, can be by the first unidirectional sluice to Na Shui in reservoir area, center, and by single slope drainage generating equipment, seawater is discharged, so, in the reservoir area, silt Ke center of seawater the inside, constantly carry out sedimentation, and silt can not taken away by tidewater.Meanwhile, due to the short silt dykes and dams that the utility model provides, be also provided with single slope drainage generating equipment, and then can utilize tidal power generation.
When the Sediment Siltation in reservoir area, center reaches after preset height, power storage capacity will reduce, while making storage capacity be not enough to support generating set generating.Now reservoir area is not dredged, but expand and prolong dykes and dams in two avris construction of center dykes and dams, expansion is prolonged dykes and dams and is connected with reservoir area, center by the first unidirectional sluice, and make expansion prolong dykes and dams and surround Cu Yu district, and the avris that dykes and dams are prolonged in expansion is provided with the second unidirectional sluice, and Cu Yu district carries out Na Shui by the second unidirectional sluice.So arrange, silt in seawater prolongs dykes and dams in expansion and surrounds and in Cu Yu district, carry out sedimentation, enter afterwards reservoir area, center, the seawater sediment charge that enters reservoir area, center is less, can not affect the electricity generate function of generating set, and then seawater can discharge reservoir area, center and generate electricity, the silt that carries out sedimentation in Cu Yu district can be avoided the impact of morning and evening tides or stormy waves equally.Sediment settlement in Dang Gaicuyu district, to certain altitude, can be close to this expansion and prolong another expansion of dam construction and prolong dykes and dams, so repeatedly, requires length Cu Yu district until along the coastline forms.
So arrange, the short silt dykes and dams for reclaiming fields from the sea that the utility model provides, the problem that not only can avoid silt easily to be taken away by tidewater, but also can generate electricity, effectively utilize tide energy. simultaneously
