The smooth shore protection of hard surface remodeling method
Technical field
The present invention relates to a kind of method of improving the riverbank bank protection, the smooth shore protection of particularly a kind of hard surface remodeling method.
Background technology
In the training works in lake, river, often construct the smooth concrete revetment of standardized hard rectilinear or ramp type.Such bank protection work for control flood and drain flooded fields, the water and soil conservation aspect played energetically effect, but this hard shore protection itself has isolated getting in touch between shore protection and the aquatic ecosystem fully, originally depending on the animals and plants and the microorganism that grow with water bank band can't survive, cause the biological chain of rivers and lakes to be destroyed, thereby cause the deterioration of whole aquatic ecosystem, deteriorating water quality.Such as a large amount of construction of the smooth shore protection of Taihu Lake Huan Hu embankment hard, destroyed original lakeside, Taihu Lake band ecosystem, also be simultaneously the major incentive that Taihu Lake water quality sharply worsens.
At present, people no longer only emphasize that the antiscour power, wind and wave resistance of shore protection washes in a pan erosion intensity etc. in the bank protection work construction of lake, river.Utilize the material of natural materials as bank protection; carry out the ecology typed bank revetment construction in conjunction with engineering, biological and ecological idea, emphasize that safety, stability, view, ecological property, naturality and the hydrophilic perfect adaptation of lake, river shore protection have become water conservancy and environmentalist's common recognition.
But before the present invention, the steel concrete hard smooth hard shore protection of having built well exists in a large number, and lack respond well to its remodeling method, again construct new shore protection if remove, be undoubtedly waste for resource, and need great human and material resources of cost and financial resources, engineering quantity is great, takes great energy time-consuming.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned defective, proposes the smooth shore protection of hard surface remodeling method.
Technical scheme of the present invention is:
The smooth shore protection of hard surface remodeling method, its major technique step is:
(1) prefabricated artificial imitated piece stone;
(2) will manually copy piece stone is placed on the smooth shore protection of the hard surface, lake, river;
(3) a plurality of artificial imitated piece stones are arranged in order, be covered with the smooth shore protection of hard surface, lake, river;
(4) will manually copy piece stone with expansion bolt is fixed on the smooth shore protection of the hard surface, lake, river.
The invention has the advantages that:
(1) method of the present invention can avoid removing original smooth shore protection, and has imitated the habitat conditions of natural shore protection to a certain extent, has realized near naturalized engineered when saving cost.
(2) method of the present invention is after transforming shore protection, makes original smooth shore protection surface irregularity, increased the roughness of shore protection, alleviated current washing away for shore protection.
(3) recess that forms between piece crack of stone crack of method of the present invention helps perching of small-sized spiral shell and small fishes, for aquatile provides nearly naturalized existence place.
(4) method of the present invention has been saved building stones owing to do not remove original shore protection, is specially adapted to the shore protection improvement project in the area of building stones shortage.
(5) method of the present invention is constructed very convenient simply, only needs in the punching of the surface of smooth shore protection, will manually copy piece stone body and function expansion bolt again and fix and get final product easy operating.
(6) the piece stone among the present invention can be by prefabrication and batch process, and quality can be effectively controlled.
Other advantages of the present invention and effect will go on to say below.

The specific embodiment
The present invention proposes the smooth shore protection of a kind of hard surface remodeling method, and its technical thought is by artificial imitated piece stone being installed in the smooth shore protection of hard surface, being increased the specific surface of the smooth shore protection of hard, for adhering to of river microorganism provides bigger space.Simultaneously, the convex-concave surface of imitated piece stone can change the water flow structure of shore protection near surface, for aquatic animal particularly mollusk such as fish and spiral shell streamy habitat conditions is provided and has perched the breeding space.
Mode below by embodiment is elaborated to technical solution of the present invention, but protection scope of the present invention is not limited to described embodiment.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4:
Artificial imitated piece stone 1 customizes in factory in advance, and its surface is concaveconvex shape, and average distance is greater than 8cm between convex peak and the spill minimum point; Be drilled with rivet hole 2 on 1 four jiaos in the artificial imitated piece stone.
At the smooth shore protection of hard scene according to the size of artificial imitated piece stone 1 at the shore protection surface drilling, pass rivet hole 2 on the artificial imitated piece stone 1 by expansion bolt by rivet again, will manually copy piece stone 1 and be fixed on the surface, hard concrete riverbank; Artificial imitated piece stone 1 can be built by eco-concrete and be formed, and its length of side size is according to the characteristics determined of the smooth shore protection of hard surface, generally can make 50X50cm square of standard.
Use procedure declaration of the present invention:
When current flow through, by the smooth shore protection body of the transformed hard of this method, having a large amount of microorganisms behind certain hour adheres at the recess of the concaveconvex shape on artificial imitated piece stone 1 surface, average distance is greater than the shape of 8cm between artificial imitated piece stone 1 rugged irregular surface and convex peak and the spill minimum point, can perch to all kinds of little mollusks the habitat is provided, comprise that mollusks such as attracting part small fishes and spiral shell perches, improved the ecological functions of original shore protection, the reparation of going down for a long time for water bank band has positive effect.
The present invention increases the specific surface of the smooth shore protection of hard, for adhering to of river microorganism provides bigger space.The convex-concave surface of artificial imitated piece stone 1 changes the water flow structure of shore protection near surface, for aquatic animal particularly mollusk such as fish and spiral shell streamy habitat conditions is provided and has perched the breeding space.
