Description
Technical field
The present invention relates to restorations of the ecosystem and sponge urban construction field, more particularly to a kind of ramp type hardening bank slope
Ecology remodeling method.
Background technique
Traditional shore protection such as often focuses on flood discharge, drains flooded fields, prevents erosion at the needs, mostly uses concrete segment, laid dry
The rigid, hards material such as stone, stone masonry, but the plant natural disposition and bioaffinity of these materials are generally poor, thus be difficult to play dirty
Contaminate the ecological environment functions such as purification, ecological diversity protection, landscape planting.In recent years, with " national water prevention and cure of pollution action meter
Draw ", the appearance of the serial policy such as " sponge urban construction action scheme ", many areas in China start to pay attention to having water purification, water suction,
The construction of the ecological bank slopes of functions such as infiltration, greening.
Hardening bank slope generallys use vertical type or ramp type structure form, and wherein ramp type has ecology renovation technique
The features such as difficulty is relatively small, ecological environment function is more significant after transformation, thus especially paid attention to.Currently used technology
Means be it is original hardening shore protection upper or build be suitable for plant growth plant cover concrete or its product (generally also claimed
For eco-concrete or green concrete), which can carry out a degree of vegetation to rigidity revetment and cover green, but apply
It is transformed in the ecology of the natural water bodies hard bank slope such as river, pond, reservoir, vegetation is difficult on the shore protection of position below abundance of water position
Normal growth, thus it is not satisfactory to the improvement of water body self-purification ability.Further, since being limited to plant cover concrete or its system
The cladding thickness of product and vegetation require, and the technical measures are also extremely limited to the pollution interception function of rainwash.
Currently, the patent of invention that number of patent application is 201511019060.9, it is unrestrained to disclose a kind of purified water type ecological revetment
Streaming system, the ecological revetment cross flow system include the diversion traverse furrow set gradually along slope surface to water surface direction, deceleration weir, reaction
Pond, gabion shore protection, the side of reaction tank are equipped with separation layer, reaction tank set gradually from top to bottom plantation layer, absorption-nitrification layer,
Metalling and anaerobism-denitrification layer are equipped with the discharger tilted down along water surface direction in metalling.But this method is undeclared
Ecological revetment cross flow system adapts to the variation of water level, and the influence to silt underwashing, self-purification of water effect are unable to get guarantor
Card.
Summary of the invention
The present invention is for the prior art is not satisfactory to the improvement of water body self-purification ability and dirt to rainwash
Dye interception function the shortcomings that also vegetation is difficult normal growth on extremely limited and abundance of water position hardening bank slope below, provide one
The ecology remodeling method of kind ramp type hardening bank slope, this method, which has, intercepts rainwash pollution, enhancing self-purification of water energy
The advantages of power, construction shore protection ecoscape.
