Problems solved by technology

However, if the submerged dam 10 reclamation method is used, there will be more sediment in the turbid water body entering the central reservoir area through the crest of the dam at high tide, and these sediments will not be carried out by the ebb tide after settlement, which will cause serious siltation in the central reservoir area , the cost of dredging will be greatly increased after long-term siltation

Embodiment 1

[0047] Embodiment 1: a kind of siltation promoting dam, such as figure 1 with 2 As shown, it includes a dam body 1 built along the coastline and whose upper end is higher than sea level. The dam body 1 and the coastline are surrounded to form a central reservoir area. Several water inlets 2 and water outlets 3 are arranged on the dam body 1. The water inlet 2 and the outlet The water outlet 3 is opened and closed by the first sluice 4 and the second sluice 5 respectively, wherein the water inlet 2 is opened at the upper end of the dam body 1 corresponding to the low sand content water layer, and the water outlet 3 is opened at the lower end of the dam body 1 corresponding to the high sand content water layer The water inlet 2 flows the seawater with less sand on the upper surface into the central reservoir area, and then the water outlet 3 flows the lower water body in the central reservoir area into the outer seawater, and at the same time brings out the silt at the lower en...

Embodiment 2

[0049] Embodiment 2: as figure 1 with 2 As shown, the difference from Embodiment 1 is that the above-mentioned first water gate 4 includes a gate 41 and a driving member 43, and a section extends from the edge of the gate 41 to form a fixed seat (not shown in the drawings), on which a rotating shaft is vertically fixed 44 and the rotating shaft 44 is inserted into the dam body 1, so that the gate 41 is rotationally connected to the dam body 1, and a connecting rod 42 is fixed on the rotating shaft 44. By driving one end of the connecting rod 42 to move up and down, the gate 41 is driven to rotate, and the water inlet is opened and closed. 2. Wherein, the outer diameter of the gate 41 is larger than the outer diameter of the water inlet 2; the second water gate 5 and the first water gate 4 are set equal.

[0050] refer to figure 1 , wherein, the first sluice 4 and the second sluice 5 are both arranged inside the dam body 1, and the dam body 1 is respectively provided with a...

Embodiment 3

[0054] Embodiment 3: a kind of silt promoting method, such as Figure 1-3 shown, including steps:

[0055] A dam body 1 whose upper end is higher than sea level is built along the coastline, and the dam body 1 and the coastline are surrounded to form a central reservoir area. Several water inlets 2 and water outlets 3 are arranged on the dam body 1 in dislocation, and the water inlet 2 and the water outlet 3 Opening and closing through the first sluice 4 and the second sluice 5 respectively, the water inlet 2 is opened at the low sandy water layer at the upper end of the dam body 1, and the water outlet 3 is opened at the high sandy water layer at the lower end of the dam body 1;

[0056] A filter screen 61 is arranged in the water inlet 2, one side of the filter screen 61 abuts against the first water gate 4, and a circle of deflector 62 is arranged on the other side, and the side of the deflector 62 away from the filter screen 61 is bent into an opening toward the filter. T...

Abstract

The invention discloses a siltation promotion dam. The siltation promotion dam comprises a dam body arranged along a coastline, wherein the upper end of the dam body is higher than the sea level; the dam body and the coastline encircle a central reservoir area, a water inlet and a water outlet are formed in the dam body, a first water gate and a second water gate are separately arranged at the water inlet and the water outlet, the water inlet is formed in a position, corresponding to a low sand content water layer, of the dam body, the water outlet is formed in a position, corresponding to a high sand content water layer, of the dam body, and a filter device and a drainage power generation device are arranged in the water inlet. The siltation promotion dam has the advantages that water bodies inside and outside the central reservoir area are fully exchanged, silt in the central reservoir area is reduced, and the water in the central reservoir area is kept clear.

Description

technical field [0001] The invention relates to a sea reclamation dam technology, in particular to a silt-promoting dam, and the invention also relates to a silt-promoting method. Background technique [0002] The sea water quality in many coastal waters of our country is turbid and the water body landscape is poor, which is not conducive to the development of some high-end coastal tourism projects. In order to solve the problem of clear water, the existing technology generally adopts the method of enclosing the sea to make the water clear, that is, firstly, a relatively closed water area is built around the sea, so that the sediment in the sea water in the relatively closed water area is deposited, and then cleared after a certain period of time. Silt, thus forming a relatively clear enclosed water area. [0003] Early sea reclamation projects generally adopted submerged dam reclamation technology. Such as Figure 4 Shown is the principle that makes seawater clear with su...
