Description

Ecological bank protection structure

Technical Field

The utility model relates to the technical fields of hydraulic engineering and water environment engineering, in particular to an ecological bank protection structure.

Background

River is an important component of the ecosystem and co-exists with animals, plants, and microorganisms. The revetment of the river channel is a joint of an aquatic ecological system and a land ecological system, and forms a living environment of various animals and plants such as fish, insects, birds, trees and the like.

In the revetment constructed in the waters such as sea area, lake, river channel, etc., a vertical revetment structure with a flat vertical surface is often adopted. However, it is difficult to grow algae such as undaria pinnatifida on the vertical surface of the vertical revetment structure, and the function of algae as habitats for aquatic organisms such as fish and shellfish is lost. In addition, a large number of shellfish and the like are easily attached to a vertical surface, and when a large number of shellfish are stacked and densely packed, they are easily dropped downward, and a large number of shellfish and the like are deposited on the water bottom near the revetment. The shellfish deposited on the water bottom is decomposed by microorganisms, and a large amount of oxygen is consumed in the decomposition process to form an anoxic water mass with low dissolved oxygen concentration. When anoxic water masses are formed, aquatic plants are difficult to inhabit, the decomposition rate of microorganisms on organic matters is also slowed down, and the material circulation of the ecological system is interrupted.

Description of the embodiments

Embodiments of the present utility model are described in further detail below with reference to the accompanying drawings.

The ecological bank protection structure is built in a water area such as seaside, lake or river, and the size and the setting position of the bank protection structure are determined according to the specific situation of the water area. In the figure, the X direction indicates the depth direction of the revetment structure, the Y direction indicates the width direction of the revetment structure, and the Z direction indicates the height direction of the revetment structure. As shown in fig. 1, the revetment structure includes a concrete retaining wall 1 forming a revetment, and the concrete retaining wall 1 is a vertical retaining wall, and may be a current retaining wall or a retaining wall under construction. The water facing side of the concrete retaining wall 1 is provided with a plurality of protruding structures 2 protruding towards the water area along the height direction, and the protruding length of each protruding structure 2 protruding towards the water area is preferably within the range of 0.2-1.5m. Specifically, the protruding structure 2 and the concrete retaining wall 1 may be formed as an integral structure, or may be fixed on the concrete retaining wall 1 by a connecting piece 5, such as an anchor rod or a reinforcing steel bar, so that the protruding structure 2 may be disassembled, thereby facilitating maintenance and replacement, and facilitating revetment repair; the bump structures 2 of the same size may be disposed adjacently in the height direction, or the bump structures 2 of different sizes may be disposed up and down so that the bump structures 2 arranged in the height direction have mutually overlapping regions and non-overlapping regions in a plan view. The protruding structures 2 may be provided at a depth where the aquatic organism c can survive, for example, at a shallow depth where the dissolved oxygen is 4mg/l or more, or at a position where the aquatic organism c is exposed to the water surface during the deliquescence.

As shown in fig. 1 and 2, the protruding structure 2 has an upper surface 21, a lower surface 22, and a corner 23 connecting the upper surface 21 and the lower surface 22, and a cantilever stand 3 fixed on the concrete retaining wall 1 is disposed below the protruding structure 2 at the bottommost. The upper surface 21 of the protruding structure 2 may be a gentle inclined surface inclined by 0-5 ︒ to the horizontal or a curved surface having small undulation, and the upper surface 21 may receive the shellfish a falling from the attached state. The corners 23 of the raised structures 2 have an obtuse angle and an acute angle, the combination of which simulates a more natural habitat environment, preferably an acute angle of 20-70 ︒, in which range algae b, especially undaria pinnatifida, grow more easily, and by the growth of algae b, a habitat or a habitat for aquatic organisms c is formed. The shellfish a attached to the lower surface 22 of the protruding structure 2 can be received by the upper surface 21 of the next protruding structure 2 after falling, so as to prevent the shellfish a from falling into the water bottom 4. The cantilever platform 3 is made of reinforced concrete materials and is used for receiving shellfish and the like falling from the upper side, and the cantilever platform 3 is fixed on the concrete retaining wall 1 through bolts.

Further, the protruding structure 2 is provided with a through hole 24, the shellfish a and the aquatic organism c can move through the through hole 24, and the through hole 24 can also be used as a hiding place for the aquatic organism c. When the shellfish a stays on the upper surface 21 of the raised structure 2, the dissolved oxygen is higher than the water bottom 4, and is easily prey on by the aquatic organisms c, and decomposed by the microorganisms, so that benign substance circulation is smoothly performed, and thus the formation of anoxic water masses at the water bottom 4 near the revetment due to accumulation of shellfish a and the like can be effectively suppressed.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the concept of the present utility model, and such modifications and adaptations are intended to be comprehended within the scope of the present utility model.
