Tropical island biological reinforcement method based on MICP and fiber traction effect
The invention belongs to the technical field of large island reinforcement, and particularly relates to a tropical island biological reinforcement method based on MICP and fiber traction effects. Comprising the following steps: (1) preparing a high-yield urease bacterium solution; (2) preparing a high-yield cellulose fungus liquid; (3) equivalently mixing the high-yield urease bacterium liquid obtained in the step (1) and the high-yield cellulose fungus liquid obtained in the step (2) to obtain a bacterium mixed cementing liquid; (4) before tide rising, the bacterium mixed cementing liquid prepared in the step (3) is added into calcium sand layers of different depths of the to-be-reinforced area of the island reef, and calcium carbonate precipitation reinforcement and fiber woven net structure reinforcement are achieved; and after tide ebb, underground water is extracted, and drying and consolidation are achieved. The method is safe, environmentally friendly, low in cost and free of pollution, the soaking-MICP-drying consolidation technology is introduced into a large island reef reinforcement protection project, and island reef reinforcement is achieved.
本发明属于大型岛礁加固技术领域，具体涉及一种基于MICP和纤维牵拉作用的热带岛礁生物加固方法。包括如下步骤：步骤(1)：制备高产脲酶菌菌液；步骤(2)：制备高产纤维素真菌菌液；步骤(3)：将步骤(1)得到的高产脲酶菌菌液和步骤(2)得到的高产纤维素真菌菌液等量混合，得到细菌混合胶结液；步骤(4)：涨潮前通过向岛礁待加固区不同深度的钙砂层加入步骤(3)制备的细菌混合胶结液，实现碳酸钙沉淀加固和纤维编织网状结构加固；退潮后通过抽采地下水，实现干燥固结。本发明安全环保、成本低廉无污染，将“浸泡‑MICP‑干燥固结”工艺引入大型岛礁加固的防护工程中，实现岛礁的加固。
