Ecological slope protection precast blocks and preparation method and application thereof
The present invention discloses ecological slope protection precast blocks and a preparation method and application thereof. The ecological slope protection precast blocks comprise the following raw materials: riverway sludge, a curing agent, plant source fibers and microorganism capsules, wherein the curing agent is a mixture of quick lime, fly ash, magnesium oxide and calcium sulfate; the plantsource fibers are plant straws; the microorganism capsules are formed by embedding functional microorganisms in urea formaldehyde resin; and the functional microorganisms are trichoderma reesei T131 and bacillus subtilis D9. The sludge, the plant source fibers and the microorganism capsules are cured by the curing agent to prepare the ecological slope protection precast blocks with the effects ofintercepting water body pollutants, performing field planting of plants and protecting slopes. Salt-resistant plant seeds are pre-attached in the ecological slope protection precast blocks or the salt-resistant plant seeds are sprayed to the surfaces of the precast blocks after the ecological slope protection precast blocks are paved. When the ecological slope protection precast blocks are used for tidal marsh silty bank slopes which are liquefied by meeting water and are collapsed by rainfall, the sewage nitrogen interception rate reaches 15-55%, the field planting success rate of the plantsis improved by 10-30 times, and the plant biomass is improved by 5-10 times.
本发明公开了一种生态护坡预制块及其制备方法和应用，生态护坡预制块的原材料由河道淤泥、固化剂、植物源纤维和微生物包膜体组成；固化剂为生石灰、粉煤灰、氧化镁和硫酸钙混合物；植物源纤维为植物秸秆；微生物包膜体为功能微生物包埋于脲醛树脂中形成；功能微生物为里氏木霉T131和枯草芽孢杆菌D9。通过固化剂将淤泥、植物源纤维和微生物包膜体固化成型，制成具有截留水体污染物、定植植物和护坡作用的生态护坡预制块。在生态护坡预制块中预附着耐盐植物种子或者生态护坡预制块铺设后在预制块表面喷洒耐盐植物种子。在遇水液化、降雨塌陷的海涂粉砂质岸坡使用，污水氮截留率达15%~55%，植物定植成功率提升10~30倍，植物生物量提升5~10倍。
