Sediment-based ecological slope protection structure, accurate regulation and control drip irrigation and infiltrating irrigation system and construction method
The invention provides a sediment-based ecological slope protection structure, a precise regulation and control drip irrigation and infiltrating irrigation system and a construction method.The slope protection structure comprises an MICP improved surface layer, an MICP improved middle layer and an MICP improved bottom layer which are all composed of sandy soil, biochar and organic fertilizer in different proportions, and the surface layer is mixed with plant seeds; the dripping and infiltrating irrigation system comprises a bacterial liquid storage tank, a cementing liquid storage tank, a fertilizer water storage tank, a water pump, an output liquid control valve, a main control valve, a plurality of secondary control valves, a water suction pipe, a dripping and infiltrating irrigation pipe, a main water pipe and a plurality of telescopic branch water pipes. By means of the characteristic that biochar adsorbs bacteria, the repairing effect of the MICP technology is improved, then biochar with the proportion from small to large is added into sandy soil in a sediment-based ecological slope protection base material layer from outside to inside, generated calcium carbonate is evenly distributed in the sandy soil in the depth direction, a weak slope body reinforcing area is precisely reinforced through a dripping, infiltrating and irrigating system, and the ecological slope protection effect is improved. And the slope obtains a better reinforcing effect and erosion resistance, and meanwhile, the aim of ecological protection is achieved.
本发明提供了一种泥沙基生态护坡结构和精准调控滴渗灌系统及施工方法，护坡结构包括MICP改良表层、MICP改良中层和MICP改良底层，均由不同比例的砂土、生物炭和有机肥组成，表层掺合植物种子；滴渗灌系统包括菌液蓄水箱、胶结液蓄水箱、肥水蓄水箱、水泵、输出液体控制阀、主控制阀门、若干次控制阀门、吸水管、滴渗灌管、主水管和若干可伸缩支水管。利用生物炭吸附细菌的特点，提升MICP技术的修复效果，再对泥沙基生态护坡基材层中的砂土由表及里添加比例由少至多的生物炭，实现生成的碳酸钙在砂土中沿深度方向上的均匀分布，通过滴渗灌系统对坡体加固薄弱区进行精准加固，使边坡获得更优的加固效果和抗侵蚀能力的同时兼顾生态保护的目的。
