Description
Technical field
The present invention relates to one kind to make beach engineering, and especially a kind of mixing dam body permeable ecology makes beach engineering.
Background technique
According to the correlation of beach body and riverbank, beach body can be summarized as three types: point bar, channel bar and the continent beach Tou Di.
Point bar is to depend on a bank, the beach body substantially in the same direction or little the angle of cut with water flow.The essential characteristic of point bar are as follows: beach body is usually located at slow
Area is flowed, straight relax in river is distributed in.Beach body is connected with close, to have semi-detached (there are string ditches) with riverbank.Channel bar is
Relatively independent underwater siltation body.The essential characteristic of channel bar are as follows: be normally at and relax in river, what is had is more stable, and some is not
Stablize.Stablize channel bar and is normally at non-mainstream area, it is short gentle, it is more complete；Unstable channel bar be normally at the variation of big vast low water compared with
Big main stream line fluctuation zone.The continent beach Tou Di is the underwater extension of middle bar continent head.The essential characteristic on the continent beach Tou Di are as follows: be located at
Diffusion region is shunted, end slope is relatively slow, and tail portion is steeper, is in front-low-rear-high shape.Beach body is connected with close, some half points with continent body
From (string ditch), the continent beach Tou Di form is related to the differentiation of two branchs of a river, and in general, which branch of a river the low beachhead portion in continent is biased to, which branch of a river
It tends to fail.Making beach is to take certain measure, promotes sediment siltation around the body of beach, and then mould good beach volume morphing.
Silt rush silt is referred to and makes to be transported in the form of bed load and suspended load by boundary condition, the dynamic condition etc. for changing water flow
Dynamic silt is converted to the bed material load stationary in bed surface.For engineering viewpoint, promote silt erosion control refer to by build groynes,
The entities building such as longitudinal dike, or build pile, set up wire netting, the permeable structures such as flexible floating curtain of jettisoninging, and planted on beach face
Water plant is planted, to change the dynamic condition of water flow, sediment movement, makes the reduced velocity flow of water flow or forms reflux, silt is made to exist
Bottom falls silt with aggradation bed surface, to protect the basis of beach face and various hydraulic structures from current scour.
Interior korneforos promotees silt erosion control technology and is broadly divided into 3 major class by the pattern of works: the impermeable water type of entity, the ecotype and its
His novel structural shape.The impermeable water type of entity, which promotees silt erosion control technology, mainly dykes and dams (including groynes, longitudinal dike, dam group, cofferdam)
And thin plate, application of this kind of technology in China is relatively early and very extensive, and construction experience is mature, and it is obvious to promote silt erosion control effect.It is raw
State type promotees silt erosion control technology and refers in seashore or shallow water bottom planting aquatic plants, stops water flow and mud with its flourishing rhizome
Sand, the technology utilize ecological organization's function, water flow are made to slow down naturally, and silt falls silt and stablizes, persistently.In recent years, although in life
State, which promotees to become silted up, to be made in beach and possesses some special knowledge, but the technology that can promote and apply or very limited, as country is to inland river ecological, environmental protective
Demand is more and more, and urgent need develops ecology that is novel and being rapidly and effectively applied to cruiseway and makes beach engineering.
Summary of the invention
The present invention is to solve technical problem present in well-known technique and provide in one kind can be rapidly and effectively applied to
The mixing dam body permeable ecology in river navigation channel makes beach engineering.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that a kind of mixing dam body is saturating
Water type ecology makes beach engineering, and the engineering installation is in channel bar and secondary channel upstream, and fourth longitudinal dike and setting including fair current setting are in institute
The groynes of fourth longitudinal dike upstream is stated, the length of the groynes is less than the length of the vertical embankment section of the fourth longitudinal dike, in the fourth longitudinal dike
It is designed with flowing hole on the groynes, area II of back-silting is equipped between the fourth longitudinal dike and the groynes, in the fourth longitudinal dike
Dam body after be equipped with and back-silt area I.
The groynes at least 2, all groynes are spaced apart, and are equipped with and are back-silted between two adjacent groynes
Area III.
The groynes has 2~5 groups, and every group includes at least two, the equal length of every group of groynes, and two adjacent groups groynes is close
The fourth longitudinal dike it is longer, be equipped with area of back-silting between the two neighboring groynes between two adjacent groups groynes and in every group of groynes
Ⅳ。
The length of the groynes is 80~100m, and the diameter of the flowing hole is 8~10m.
The advantages and positive effects of the present invention are: one) use combined type permeable dike group structure, both can with overcurrent,
Flow rate of water flow can be slowed down, be conducive to the siltation of silt around the body of beach, make beach effect with good；Two) saturating using combined type
Dam group structure, so that the velocity field on point bar periphery becomes rich and varied, for the water plant around the body of beach, aquatic meiofauna
It is provided with microorganism and survives, inhabites, laying eggs, the suitable space of forage.During making beach, can more further it enrich
Aquatic ecological environment around the body of beach.Therefore the present invention can be rapidly and effectively applied to cruiseway.
