Description
Technical field
The present invention relates to a kind of mountain stream dyke anti-impact shore protection and installation method, belong to hydraulic engineering field.
Background technology
Current mountain stream shore protection generally uses jackstone, cemented rock shore protection, due to jackstone, cemented rock shore protection globality
Difference, during riverbed is adjusted with current, partial block stone is easy to lose, and influence bank-protection works stability is reinforced, it is necessary to often safeguard.
Still further aspect, the mass exchange that jackstone, cemented rock shore protection have completely cut off between soil and water body destroys bank slope ecological nearby
System；Realizing with human ecology strengthens, and gradually recognizes that river regulation in addition to flood control safety is met, should also take into account ecological ring
Border, thus, ecological revetment arises at the historic moment.Ecological revetment pattern mainly has compound grass planting bank protection, precast hollow block both at home and abroad at present
Bank protection, radial type slope-protection block, cobble basket structure, prefabricated spherical eco-concrete bank protection, concrete grid grass planting bank protection, jackstone+
Grass planting bank protection etc. is several.For mountain stream, above-mentioned shore protection pattern erosion-resisting characteristics is poor, it is difficult to phase high speed water flow of keeping the flood in check
Impact, causes dyke to destroy, and greater loss is brought to people's lives and properties, is badly in need of a kind of effective anti-impact shore protection pattern, and take into account
It is ecological.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention to provide a kind of mountain stream dyke anti-impact
Shore protection and installation method, stream design is chosen by using continuous, changes side slope flow direction nearby, its impact is not influenceed by stream is chosen
Current, generation crosses, blends consumption kinetic energy, on the one hand changes flow direction and reduces directly washing away for side slope, still further aspect
Side slope water flow dynamic energy nearby is reduced, so that it is guaranteed that the stabilization of bank protection structure.
Technical scheme：In order to solve the above technical problems, mountain stream dyke anti-impact shore protection of the invention, including some groups of phases
The shore protection unit for connecting, comprising being coupled post, choosing stream plate and stability column, the stream plate of choosing is streamlined, institute to the shore protection unit
State and be coupled post and be connected with the bottom for choosing stream plate, the stability column flows plate and is connected and supports and choose stream plate with choosing, upstream shore protection unit
Stability column is mutually socketed with the post that is coupled of downstream shore protection unit.
Preferably, the connection post and stability column are located in same vertical plane.
Preferably, the connection post head is " recessed " shape, stability column afterbody is " convex " shape, and the insertion of stability column afterbody is coupled
In post head, square opening is opened at center, and affixed using lock pin.
Preferably, connection post in each shore protection unit, choosing stream plate and stability column entirely through concrete prefabricated.
Preferably, the connection column length is L1, it is 5~25 ° to choose stream plate and choose stream angle θ scopes, chooses stream plate plate in level
The length projected on face is L2, wherein L2Equal to 1.0-2.5 times of L1, current are bigger with bank slope angle, choose stream angle θ it is smaller, water is flowed through
After choosing stream plate water conservancy diversion, L2Length ensure that current fall directly into next piece and choose stream plate, and realization continuously chooses stream.
The installation method of above-mentioned mountain stream dyke anti-impact shore protection, comprises the following steps：
1) use connection post that concrete processed in shore protection unit in integral prefabricated mode, choose stream plate；
2) between lowstand period, by shore protection shipped to place to be installed；
3) downstream shore protection unit is first installed, then upstream shore protection unit is installed, the stability column insertion downstream of upstream shore protection unit
Shore protection unit connection post is simultaneously affixed with lock pin；
4) it is coupled plane and bank slope planes align on post, bottom is embedded in bank slope；
5) it is being coupled intercolumniation and is choosing the vacant ground plantation vegetation such as stream plate bottom, is preventing erosion；
6) similarly, according to above-mentioned steps 3) to 5) being sequentially completed installation.
Preferably, the step 1) in, the connection in using concrete to process shore protection unit in integral prefabricated mode
Post, choose stream plate and stability column when, comprise the following steps：
1. parameter θ, L are determined according to model test1And L2, whether evaluation criterion is to be formed continuously to choose stream, and stream is chosen through choosing stream plate
Current after effect are back to be considered as when stream plate is chosen in downstream continuously chooses stream；Wherein, θ chooses stream angle, L to choose stream plate2To choose stream plate
The length for projecting in the horizontal plane, L1To be coupled column length；
2. according to θ and L2It is determined that choosing stream board parameter, it is the corresponding shape and size of 1/4 ellipse, transverse a to choose stream plate
=2*L2, ellipse short shaft b=2*L2*tanθ；
3. according to parameter θ, L1、L2, a and b, use connection post that concrete processed in shore protection unit in integral prefabricated mode,
Choose stream plate and stability column.
In the present invention, stability column one end is connected with Tiao Liuban centers, and other end exists in the intersection point of horizontal plane with stream plate is chosen
Projection on horizontal plane overlaps.Parameter θ, L are determined according to model test1And L2Specific method be：1) model test is used, is used
The prototype the side slope ot the embankment that the dyke modeling present invention is applicable, wherein level is more identical with vertical scale than chi, is 2 than chi scope
~6；2) flow direction near measurement side slope, obtains it with side slope angle α；3) under original state, if α is more than 25 °, θ settings
It is 25 °, on the contrary θ is set as α, L1It is set as 1m (in order to transporting and installing), L2It is 1.2m, is made and the present invention according to than chi
The mountain stream corresponding bank protection structure model of dyke anti-impact shore protection；4) bank protection structure model is arranged in dyke model, is measured
The neighbouring flow rate of water flow of stability column downstream side slope, the flow velocity increases finally tend towards stability gradually in a downstream direction, occurs first most
Big flow velocity point is considered as and is back to side slope again by the current chosen after stream effect, along side slope distance is L between the point and stability column3,
As shown in figure 3, dotted portion is L3Length range；If 5) L3More than L1, then bank protection structure is reasonable, on the contrary increase L2, repeat to walk
It is rapid 4), to L3More than L1, it is determined that θ, L1And L2Parameter.
Beneficial effect：Mountain stream dyke anti-impact shore protection of the invention and its installation method, continuously choose stream and set by use
Meter, current first motion in the case where stream plate guide functions are chosen chooses stream plate to next piece, should during choose the current after stream and do not chosen
Stream effect current cross, and mutually blending consumes water flow dynamic energy, while forming recirculating zone stream plate bottom is chosen, flow velocity significantly reduces,
It is coupled the vacant ground vegetation of post so as to be conducive to safeguarding, prevents erosion, realizes side slope protection.The present invention improves bank protection structure
Stability, at the same the shore protection pattern not solidify dyke domatic, allow Soil Slope to be fully contacted with current, it is ensured that it is domatic with water body it
Between material interaction, maintain bank slope nearby the ecosystem.
