Description

Wave-proof algae-controlling ecological dike

Technical Field

The utility model relates to an ecological remediation technical field relates to a wave-proof accuse algae ecological embankment.

Background

The breakwater of the lake can prevent water body from leaking, prevent silkworm food on the water surface of the lake to a great extent, ensure the harvest of the reclaimed cultivated land, and simultaneously, the breakwater is matched with other hydraulic engineering, so that the life and property safety of people along the bank can be ensured. With the construction of the breakwater, the original shoals around the lake do not exist, and the ecological balance of the lake is broken; the habitat on which the aquatic vascular bundle plants live is damaged, and the aquatic plant population in a large area of the lakeside zone basically disappears.

The lake bank design in the common river and lake ecological restoration method mainly takes vegetation bank protection as a main part, and the lakeside is more natural through the flexible treatment of the vegetation on the lake bank. However, the breakwaters are directly dismantled to prevent the plants from waves, the plants are difficult to fix the roots under the influence of the waves in the lakes, and the algae in the lakes can enter the shallow water areas of the lakesides in a large area, so that the water quality of the shallow water areas is deteriorated. Therefore, it is important to ensure the hydrologic exchange between the lake water area and the shoreline shoal and prevent the algae in the lake from entering the shoal wetland.

SUMMERY OF THE UTILITY MODEL

For solving above problem, a wave-proof algae control ecological embankment, including bank base, scour prevention district and vegetation district, the scour prevention district sets up on the bank base and is located and is close to water one side position department, the vegetation district sets up on the bank base and is located and keeps away from water one side. Through arranging scour prevention district and vegetation district in proper order on the bank base, the scour prevention district can effectively avoid lake wave direct scouring vegetation district, so set up more to be favorable to the vegetation to consolidate the root.

Furthermore, the ecological embankment further comprises a soil stabilization layer, wherein the soil stabilization layer is paved on the surface of the shore base and enables the shore base to form a structure with the middle part protruding higher than the horizontal plane and the two sides recessed lower than the horizontal plane.

Furthermore, the soil stabilization layer is formed by stacking and paving cobblestones, the width of the cross section of the soil stabilization layer in the vertical direction is 3-4 m, and the width of the part, protruding from the middle of the soil stabilization layer, higher than the horizontal plane is 60-80 cm.

Furthermore, the side of the soil stabilization layer close to the water body is a near water side, the anti-scouring area is formed by piling broken stones with the size of 0.5-2 meters, the anti-scouring area is located on the near water side of the soil stabilization layer, and the anti-scouring area is piled upwards to a high water level along the vertical direction from the lower part of the horizontal plane.

Furthermore, one side of the soil stabilization layer, which is far away from the water body, is a far water side, the vegetation area is arranged on the far water side of the soil stabilization layer, and the planting width of the vegetation area is 5-10 meters.

Furthermore, the cobbles laid on the soil stabilization layer are 5-25 cm in size. When the sizes of the cobblestones in the solid soil layer are too small, the cobblestones easily enter the water body under the washing of the water body to cause the solid soil layer to be damaged, and when the sizes of the cobblestones are too large, gaps among the cobblestones are too large, so that water and soil on a shore base cannot be effectively protected, and water and soil loss is caused.

Furthermore, the scour prevention area built by the broken stones is provided with a highest point I, the middle protruding position of the solid soil layer is provided with a highest point II, and the height of the highest point I and the height of the highest point II are at the same horizontal height.

Detailed Description

Fig. 1 is a schematic structural diagram of an embodiment of the present invention. It should be noted that in the description of the present specification, the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

As shown in the figure, this embodiment forms a wave control algae ecological embankment through disassembling the transformation to original breakwater 5, including bank base 1, solid soil layer 4, scour prevention district 2 and vegetation district 3, the scour prevention district sets up on the bank base and lies in and is close to 6 one side positions of water department, the vegetation district sets up on the bank base and lies in and keeps away from 6 one sides of water, solid soil layer lays in the bank and is used for preventing the soil erosion and water loss of bank base. Through having the water to arrange scour prevention district and vegetation district to the inland bank in proper order on the bank base, the scour prevention district can effectively avoid lake wave direct scour vegetation district, so set up more to be favorable to the solid root of vegetation.

In this embodiment, firstly, solid soil layer 4 is laid, solid soil layer 4 is formed by the cobblestones through piling up and laying, as shown in the figure, solid soil layer lays in bank base surface and makes bank base form the structure that middle part is protruding to be higher than the horizontal plane, both sides are sunken to be less than the horizontal plane. The sizes of the cobblestones paved on the soil stabilization layer are 15 cm, when the sizes of the cobblestones on the soil stabilization layer are too small, the cobblestones easily enter a water body under the washing of the water body to cause the damage of the soil stabilization layer, when the sizes of the cobblestones are too large, gaps among the cobblestones are too large, water and soil on a shore base cannot be effectively protected, water and soil loss is caused, when the cobblestones are paved, the sizes of the cobblestones are kept consistent as much as possible, certain difference is allowed to exist among the cobblestones, and the differences are controlled to be 5-25 cm. When the soil stabilization layer is laid, the width of the vertical section of the soil stabilization layer is 3.5 meters, and the width of the part, higher than the horizontal plane, of the middle bulge of the soil stabilization layer is 70 centimeters. One side of the soil stabilization layer close to the water body is a near water side, and one side of the soil stabilization layer far away from the water body is a far water side.

In this embodiment, the breakwater 5 is removed to a position 20 cm below the water level, the erosion prevention area is disposed on the near-water side of the soil stabilization layer, the removed portion of the breakwater is cut into broken stones in this embodiment, and the erosion prevention area is formed by stacking the broken stones. The size of the crushed stone is controlled to be 1 meter, the specific size of the crushed stone can float up and down on the basis of 1 meter, but the size of the crushed stone is controlled to be 0.5-2 meters. Scour prevention district is piled up to going out the water level by below the horizontal plane along vertical direction upwards, scour prevention district piled up by the rubble has a culmination point I, the bellied position in solid soil layer middle part has a culmination point II, the height of culmination point I and the height of culmination point II are at same level. The breakwater must be dismantled below water level to avoid affecting normal water exchange.
