Description
Technical field
The invention belongs to waterway regulation technical field, especially a kind of local overcurrent ecotype groynes.
Background technique
China has a vast territory, and rivers gather.In controlling river and water transportation construction project, groynes is inevitably used
Structure.In river engineering, groynes is one of most widely used building；In flood control works, groynes can be used for protecting river
Bank is from washing away；In waterway regulation works, groynes can be used for the narrow riverbed of beam, scouring depth navigation channel, i.e. " clearing sands with converging flow "；It is enclosed in river shoal
It cultivates in engineering, builds groynes (group) first usually to promote to become silted up.
Groynes design only was carried out from hydrodynamics and the angle of structural mechanics in the past, few combination ecology and aquatic
Biological need end carries out the design of groynes structure.Under normal circumstances, silt can deposit behind dam forms dam field, is that fish etc. are aquatic
The good habitat of biology, but maximized in traditional groynes structured design process in order to seek project benefit, often groynes is designed
For continuous, fluid-tight solid groin, on the one hand ignores as aquatile there are habitat and migration channel is inhabited, plant
Object is difficult to grow at groynes and inhabit with animal；It is difficult to form the unified organic ecosphere with dam field thereafter, is unfavorable for groynes week
Enclose the maintenance in habitat.Water flow structure is more complicated at another aspect groynes, since area of passage is smaller, so that section where groynes
Flow velocity is larger, water flow for a long time wash away under, dam body surface layer block stone easily slides, and causes local buckling, and plant is also difficult to adhere to.
Therefore, there is an urgent need to develop a kind of configurational stabilisation, environmentally protective, the groynes knot of hydrophilic close friend in ecology on material
Structure, it is desirable that it can either guarantee the stabilization of dam body, meet the needs of navigation, and can build good habitat for animals and plants.
Summary of the invention
The present invention is to solve technical problem present in well-known technique and provide one kind and be capable of the ten of enhancing structure stability
Letter stencil stake ecotype groynes.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that a kind of cross sheet pile is raw
State type groynes, the two row cross sheet piles including being separately positioned on basic two sides, each cross sheet pile are equipped with right-angled intersection
Level board and vertical plate are equipped with permeable hole on the level board of the cross sheet pile and the vertical plate of the cross sheet pile,
The level board of the cross sheet pile is arranged on surface of base, and bottom plate is equipped between the level board of cross sheet pile described in two rows,
Between the level board of the cross sheet pile of in same a line, adjacent two and level board and the institute of the cross sheet pile
It states and is equipped with expansion joint between bottom plate, be formed with dam body and abutment between the vertical plate of cross sheet pile described in two rows.
It is located on the surface on groynes design water level in the dam body and the abutment and is covered with alloy steel cage gauze pad,
It is successively arranged plant-growth carpet, organic matter soil layer and natural gravel layer from bottom to up in the cylinder mould of the alloy steel cage gauze pad,
The organic matter soil layer has included plant grass seeds and organic fertilizer.
The vertical plate top mark height of the cross sheet pile is concordant with groynes design water level, outside the vertical plate of the cross sheet pile
Side is equipped with the groynes bottom side slope built up by lattice guest's gabion net cage.
The lattice guest's gabion net cage for building up land side groynes bottom side slope is equipped with the network management of vertical groynes axis.
The cross sheet pile is made of concrete, and the vertical plate of the cross sheet pile is equipped with bottom cutting edge, described
Reinforcing bar is placed with inside the cutting edge of bottom.
The dam body and the abutment are all made of jackstone structure.
The plant-growth carpet is made of natural degradable fibrous material.
The advantages and positive effects of the present invention are:
1. the self weight of dam body of the cross sheet pile by the drag of the soil body and ballast on it comes together to resist water flow
Impact force changes the loading characteristic of structure, greatly strengthens the stability of structure, provides for dam field thereafter relatively stable
Fluidised form environment.2. dam body main structure is to dissipate jackstone, and be covered with alloy steel cage gauze pad on it, material has good
The ecotype, the mud between stone gap are conducive to benthon and plant growth attachment.3. groynes design water level backwater below
Bottom side slope uses lattice guest's gabion equipped with network management to take and build, the network management in lattice guest's gabion under the water blocking effect of groynes, fluidised form compared with
For stabilization, it can be used as the aquatiles such as fish and ideal protection place be provided.In conclusion invention enhances the steady of dam body
It is fixed, meet navigation needs, while dam body and its surrounding ecological environment can be improved again, is that the construction of the rivers biologies such as fish is good raw
Border meets engineering construction and protects the needs of environment.
