Abstract

The present invention is a kind of regular hexagon and the composite ecological floating island for having biofilm system.The chinampa can individual unit independent operating or multiple units be operated together by fixing buckle connection to adapt to the processing of the water eutrophication under different situations or greening and require.In detergent power, the design early period is leading by growing rapid draft class plant, mid-term is purified water by molding biofilm components with herbaceous plant jointly, later period is occupied leading by the woody plant strong to water body purification ability, maximum net outlet capacity is played, the three stage purifying water effects for being similar to logistic curve are presented.System has more stability, greatly improves the self-purification ability of enviroment.It in structure, according to bionics principle, is designed referring to honeycomb structure, realizes that the knockdown mode of singulation can be according to different waters, different water surface flexible in size adjustment volumes and chinampa distributing position, building mode are flexible.

Description

A kind of honeycomb type ecoscape type chinampa

Technical field

The present invention relates to a kind of ecoscape chinampa for environmental protection more particularly to a kind of assembled ecological landscape are floating Island can be applied to the restoration of the ecosystem of the water bodys such as river, lake, lagoon, bay.

Background technique

China is the country in lake more than one, and more than 20,000 lakes account for 1/10th of world's natural lake, however according to Investigation to the 25 medium-and-large-sized lakes in China has tended to the lake of eutrophication up to 92%.Trunk river majority section water quality is bad InClass standard.And only by taking wawter bloom event as an example, report of the Chinese Central Television (CCTV) in 2007, only Wuhan Caidian District blue algae bloom Single event have led to 200,000 jin of fish death, causing economic loss is more than 700,000 yuan.Water eutrophication problem at For the Important Problems of country.However the mode that the problem of for the outburst etc of cyanobacteria also can only just use prevention plus administer, place Reason means are very single.

Ecological floating island technology is a kind of ecological engineering technology of the ecological environment of diversification for eutrophication water quality, The staggered characteristic of root system of plant packing is utilized, forms one layer of dense net, and in adsorbed water body while suspended matter Root system surface forms biomembrane, and the pollutant decomposed in water is inorganic matter, provides nutrient for plant.And plant is absorbing nutrient Meanwhile also having adjusted the nutritive salt ratio in water body.By the interception on chinampa, the overgrowing of Measures of Algae in Water Body will be pressed down System, and then improve the transparency of water body.The existence that can also be had a rest for the short distance of birds with fish while purifying water body Procreation, which provides, protects place.

Summary of the invention

It is an object of the invention to: a kind of ecoscape chinampa for environmental protection is provided.To the detergent power of water body With more diversification, stability, purification efficiency is higher compared with Traditional Ecological chinampa.Its structure of regular hexagon is more stable, can resist Higher level-one stormy waves.By can also further resist water erosion, salt water corrosion to the preferred of material.To be suitble to more More water body environments, service life are permanent.And hexagon shaped cell structure make its and combinations thereof form in structure have more aesthetics, It is unique.Difference is shown in landscape arrangement.

Similar and regular in the upper modular construction of production, the mode that can easily pass through 3D printing or assembly line carries out component Production.In installation, factory preassembling may be implemented, road transport is lauched the scheme for placing three-step-march.Pass through modularity Form, the duration also greatly shortens while possessing purification efficiency.

As preferably 1, the ecological floating island is with regular hexagon column type.

As preferably 2, the float structure uses cenosphere composite epoxy resin base syntactic foam (HGMs-EP Syntactic foam), thus when Density Distribution it is more evenly controllable, the pressure-resistant performance of floating body part is stronger, and water absorption rate is low, buoyancy dissipate It loses slow.Service life greatly prolongs.

As preferably 3, float structure is located at the chinampa bottom, to avoid float structure and frame structure in vertical direction On obscission.A large-scale circular hole up and down is opened at float structure center, so that center of gravity is toward middle part when ecological floating island It concentrates, more stability when floating in water, it is smaller to the pulling force of bottom stake.Simultaneously the cavity can as the inlet and outlet of water flow, Water body purification ability is promoted in vertical direction.It is not easy to form dead water region, causes water body smelly or mosquito breeds.During installation Chinampa enters water also more rapidly.

As preferably 4, framework uses the glass fiber reinforcement vinyl based composites by interface optimization.Enhance frame The Salt-resistant alkali-resistant ability of body.The service life being lifted under saline-alkali environment.Material is environment-friendly materials simultaneously, and when recycling is easier to locate Reason.

As preferably 5, the form reinforcement by connection that joggle is all made of between framework and floating body, framework and framework is fixed.To real The fixation that metal is used for key position is now reduced as far as possible, is fallen apart problem to avoid because of ecological floating island caused by corrosion of metal. Simultaneously regular hexagon add the form of joggle also by be framework part structure more closely, robustness is higher.Framework and floating body By way of joggle will also floating body and frame obscission in the horizontal direction can also be avoided while increasing contact area.

As preferably 6, in the position of framework connection floating body, there are intake-outlets for chinampa side, enhance the water in horizontal direction Body detergent power.It is not easy to form dead water region, causes water body smelly or mosquito breeds.Chinampa enters water also more rapidly during installation. Can may be used as simultaneously attachment device between chinampa unit and unit pre-manufactured hole and with lakebed stake rope junction.

As preferably 7, floating body upper layer is the bracket of bamboo mat shape and the thick nylon rope fishing net of fine mesh, so that biology be avoided to fill out The passage of material and planting soil.

As preferably 8, biologic packing material part uses the compound PVFM(polyvinyl formal of hemp) suspension condiment is (light Water) or the compound PVFM floating stuffing (salt water) of sisal fiber.Sisal fiber can be greatly enhanced as load in salt water environment The tolerance of salinity, filler is not perishable, causes secondary pollution.And PVFM can then make filler have certain three-dimensional structure biological more Well, while also possessing has the characteristics of strong stretch-proof, corrosion-resistant, heat-resisting, light shine, degradation resistant.By the two is compound can be with While further increasing its performance, reduce the unit cost of production.And more crucially material is environment-friendly materials, is convenient for Resource reclaim.

As preferably 9, one layer of biologic packing material layer and large mesh thick nylon rope fishing net are being covered in plantation figure layer, is being avoided Planting soil passage in special circumstances.
