Abstract
The utility model discloses a kind of for guarding the curved opening ecology dam structure on continent beach, including be arranged in front of the beach of continent, nock backwards, arc dam body that radian is adapted to continent beachhead portion form, arc dam body is equipped with preceding side slope and rear side slope, is equipped with multiple overcurrent notches being evenly arranged at the top of arc dam body.The utility model uses arc dam body, is arranged in front of the beach of continent, screens continent beach preferably, from the direct impact of water flow, to keep the stabilization on continent beach；It does not directly overlay on the beach of continent, vegetation, fish spawning ground of phytal zone on the body of beach etc. is not destroyed, to reduce the change to river ecological, Biotope Landscape；It can guarantee that some water flow flows through dam body from overcurrent notch when river is in low water level using overcurrent notch arrangement is equipped in dam crest, to be conducive to the area of slack water that aquatile inhabites after building dam body；Overcurrent notch on dam body is also that the aquatiles such as fish remain channel, reduces barrier of the building to aquatile.
Description
Technical field
The utility model belongs to waterway regulation technical field, especially a kind of for guarding the curved opening ecological dam on continent beach
Body structure.
Background technique
Dividing distributary type is a kind of common fluvial morphology, since, there are middle bar or channel bar, water flow is divided into two in river
The branch of a river or more branchs of a river.In braided rcach waterway regulation works, it is often necessary to guard continent beach unstable in river, with stabilization
Section swale pattern, improves the Channel Condition in river.Currently, the continent beach guarded in braided rcach frequently with project have shield
Bank engineering, shield beach band engineering etc..Bank-protection works, shield beach band engineering are all made of and arrange on continent body or beach body or jackstone, to engineering
Biotope Landscape change in region is larger, is unfavorable for the stabilization of river ecological.
Summary of the invention
The utility model is to solve technical problem present in well-known technique and provide a kind of for guarding the arc on continent beach
Be open ecological dam structure, the structure ensure that middle bar or channel bar are guarded and under the premise of stable engineering objective, sufficiently
Consider the ecological effect of engineering, reduces influence of the engineering to river ecological, promote the improvement in local biologic habitat, built to reach
If the target in ecological navigation channel.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique: one kind is for keeping
The curved opening ecology dam structure on the beach Hu Zhou, including be arranged in front of the beach of continent, nock backwards, radian and continent beachhead portion shape
The arc dam body of state adaptation, the arc dam body are equipped with preceding side slope and rear side slope, are equipped at the top of the arc dam body multiple
The overcurrent notch being evenly arranged.
The width of the overcurrent notch section is 3~5m, is highly 2~4m.
The gradient of the preceding side slope is 1:1~1:1.5, and the gradient of the rear side slope is 1:1.5~1:2.5.
The arc dam body is made of being built as stone material or precast concrete.
The utility model has the advantages and positive effects of: 1) use arc dam body, be arranged in middle bar or channel bar it
Before, screen middle bar or channel bar preferably, from the direct impact of water flow, to keep the stabilization on continent beach.2) dam body
It is arranged before continent in the middle of a river or channel bar, does not directly overlay on the beach of continent, the fish of the vegetation, phytal zone do not destroyed on the body of beach produces
Ovum field etc., to reduce the change to river ecological, Biotope Landscape.3) it is equipped with overcurrent notch arrangement using in dam crest, works as river
When stream is in low water level, it can guarantee that some water flow flows through dam body from overcurrent notch, to be conducive to aquatic life after building dam body
The area of slack water that object is inhabited.4) the overcurrent notch on dam body is also that the aquatiles such as fish remain channel, reduces building to water
The barrier of biology.

Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing:
FIG. 1 to FIG. 4 is please referred to, it is a kind of for guarding the curved opening ecology dam structure on continent beach, including setting on continent beach 2
Front, nock backwards, arc dam body 1 that radian is adapted to continent beachhead portion form, the radian of arc dam body should be according to being kept
Depending on the continent beachhead portion form and combination experimental study of shield；Arc dam body should be built securely by design requirement is embedding, highly should be by
It is determined according to regulated water stage or experimental study achievement, the arc dam body 1 is equipped with preceding side slope 1-1 and rear side slope 1-2, in the arc
The top of dam body 1 is equipped with multiple overcurrent notch 1-3 being evenly arranged.
In the present embodiment, the width of the overcurrent notch 1-3 section is recommended as 3~5m, and highly recommended is 2~4m.Institute
The gradient of side slope 1-1 is recommended as 1:1~1:1.5 before stating, and the gradient of the rear side slope 1-2 is recommended as 1:1.5~1:2.5.It is described
Arc dam body 1 is made of being built as stone material or precast concrete.
Although being described above in conjunction with preferred embodiment of the attached drawing to the utility model, the utility model is not
It is confined to above-mentioned specific embodiment, the above mentioned embodiment is only schematical, is not restrictive, ability
The those of ordinary skill in domain is not departing from the utility model aims and claimed under the enlightenment of the utility model
In the case where range, many forms can also be made, these are belonged within the protection scope of the utility model.
