Abstract
The invention discloses a permeable ecological spur dike, wherein a plurality of permeable holes are arranged on a dike body of the spur dike, and the permeable holes are horizontally arranged, and the axes of the permeable holes incline towards the direction of a river deep groove. The inclined angle of the axial line of the water permeable hole towards the river deep groove direction is 10-12 degrees. According to the invention, the water permeable holes are arranged on the dam body, so that the local scouring strength of the dam body is reduced, and the self-stability of the structure is facilitated; the water permeable holes penetrate through the dam body and are obliquely arranged towards the direction of the deep channel of the river, so that a turbulent structure near the dam body can be effectively slowed down, and slow flow and silt promotion are facilitated; the water permeable holes can provide a certain habitat for aquatic animals such as fishes, shrimps and the like, and improve the local micro-habitat of the river. Compared with an entity spur dike, the water-permeable spur dike has certain water permeability, the scouring strength of the dam head is smaller than that of the entity spur dike, and the structure is high in safety. In addition, the permeable holes can provide a certain inhabitation environment for animals, and are beneficial to the improvement of a river micro-ecological system.
Description
Technical Field
The invention relates to inland waterway regulation engineering, in particular to an ecological spur dike structure.
Background
The spur dike is one of the most commonly used renovation buildings, the root of the spur dike is connected with the river bank, the head of the spur dike extends to the center of the river, the axis of the spur dike is orthogonal or oblique to the direction of water flow, and the spur dike and the river bank form a spur dike on the plane. The spur dike belongs to a water-blocking building and is generally built on one side of a shoal and opposite to a navigation channel. In the process of the channel renovation project, the water is used for attacking sand, so that the water flow power axis deflects and tends to the opposite bank, and the function of increasing the water depth of the navigation channel is achieved.
When the grove is punched deeply in the spur dike, the cross section of a river channel is narrowed by the spur dike, the surrounding water flow condition is changed, and a complex three-dimensional vortex is formed near the dam head of the spur dike, so that a local scouring pit is formed at the dam head of the spur dike. Particularly, the solid spur dike has high water blocking rate, the water flow is extruded to a high degree near the dam head, and the formed strong turbulent flow structure causes the local scouring of the dam head to be obvious, so that the spur dike is usually destroyed by water to harm the safety of buildings.
Disclosure of Invention
The invention provides a permeable ecological spur dike for solving the technical problems in the prior art.
The technical scheme adopted by the invention for solving the technical problems in the prior art is as follows: the utility model provides an ecological spur dike permeates water, is provided with a plurality of holes of permeating water that run through on the dam body of this spur dike, the hole level that permeates water sets up, the axis is to river deep trouth direction skew.
The inclined angle of the axial line of the water permeable hole towards the river deep groove direction is 10-12 degrees.
The invention has the advantages and positive effects that: 1) the spur dike body is provided with the water permeable holes, so that the local scouring strength of the dam body is reduced, and the self-stability of the structure is facilitated; 2) the water permeable holes penetrate through the dam body and are obliquely arranged towards the direction of the deep channel of the river, so that a turbulent structure near the dam body can be effectively slowed down, and slow flow and silt promotion are facilitated; 3) the water permeable holes can provide a certain habitat for aquatic animals such as fishes, shrimps and the like, and improve the local micro-habitat of the river.
Drawings
FIG. 1 is a schematic view of the present invention;
FIG. 2 is a second schematic structural diagram of the present invention;
FIG. 3 is a side view of the present invention;
fig. 4 is a top view of the present invention.
In the figure: 1. a dam body; 2. an end face I; 3. an end face II; 4. a water-facing surface; 5. a water-backed surface; 6. water permeable holes; 6-1, the water-facing side; 6-2, the backwater side; 7. the axis direction of the water permeable holes; 8. the width direction line of the dam body.
Detailed Description
In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings:
referring to fig. 1 to 4, the water-permeable ecological spur dike has an end face i 2 connected with a river bank, an end face ii 3 extending to a deep channel of the river, a slope of an upstream face 4 of the dam is 1:1 to 1:1.5, and a slope of a downstream face 5 of the dam is 1:1 to 1: 2.5.
The dam body 1 is provided with a plurality of water permeable holes 6 penetrating through the dam body, the water permeable holes 6 are horizontally arranged, and the axis of the water permeable holes inclines towards the direction of a river deep groove. The water permeable holes 6 can provide habitat for aquatic animals such as fish and shrimp. It is recommended that the axis of the water permeable holes 6 is inclined at an angle of 10-12 deg. to the river deep channel direction. In this embodiment, the axis of the water permeable holes 6 is inclined at an angle of 11 ° to the river deep channel direction.
Referring to fig. 4, the axis 7 of the water-permeable hole direction formed by the connecting line of the upstream side 6-1 and the downstream side 6-2 of the water-permeable hole 6 forms a certain angle with the line 8 of the width direction of the dam body, so that the flow velocity of water in the inclined hole is reduced compared with that of a straight hole, and the silt is more favorably deposited.
Compared with an entity spur dike, the water-permeable spur dike has certain water permeability, the scouring strength of the dam head is smaller than that of the entity spur dike, and the structure is high in safety. In addition, the permeable holes can provide a certain inhabitation environment for animals, and are beneficial to the improvement of a river micro-ecological system.
Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and those skilled in the art can make many modifications without departing from the spirit and scope of the present invention as defined in the appended claims.
