Grouting device and grouting method for reinforcing rock fractures through microorganisms
The invention discloses a grouting device and method for reinforcing rock fractures through microorganisms, and belongs to the technical field of reinforcing rock fractures through microorganisms. The problems that an existing grouting mold is single in size and inconvenient to use are solved. The device specifically comprises a grouting system, a grouting mold and a recycling mold, grouting liquid is contained in the grouting system; the grouting system is connected with the grouting mold; a rock sample is fixed in the grouting mold; and the rock sample is accommodated in the recovery mold. The grouting system transports slurry into rock sample cracks, and the rock sample cracks are filled and solidified with the slurry; waste liquid flowing out of rock sample cracks after solidification flows into a recovery mold to be collected; according to the grouting method, a bacterial solution and reaction solution separated grouting mode is adopted, and the situation that calcium carbonate deposits in advance, and consequently grouting holes are blocked is avoided; a filter screen is arranged on the grouting outlet plate, so that the retention time of slurry in rock sample cracks is prolonged, and the curing effect is improved; waste liquid after each time of grouting is re-injected into rock sample cracks, so that the utilization rate of the grouting solution is improved.
本发明公开了一种微生物加固岩石裂隙的注浆装置及注浆方法，属于微生物加固岩石裂隙技术领域；解决了现有的注浆模具尺寸单一，使用不便的问题；其具体包括注浆系统、注浆模具和回收模具；注浆系统内盛装有注浆液；注浆系统与注浆模具连接；注浆模具内固定有岩样；岩样容置在回收模具内。本发明中注浆系统将浆液运输至岩样裂隙中，浆液在岩样裂隙中填充固化；固化后从岩样裂隙中流出的废液流入回收模具中收集；本发明的注浆方法采用细菌溶液与反应液分离注浆的方式，避免了碳酸钙提前沉积导致注浆孔堵塞；在注浆出口板上设置过滤网，增加浆液在岩样裂隙内的停留时间，提高固化效果；每次注浆后的废液重新注入岩样裂隙，提高了注浆溶液的利用率。
