摘要
结合某工程实例,对老采空区破碎地基注浆的相关技术进行了研究和实施。确定了老采空区地基充填注浆的范围。根据破碎地基特点和浆液扩散规律,设计了注浆的孔位,确定了注浆材料的配比和施工工艺。检验孔的钻探结果表明,实际的注浆效果达到了设计目的,地基强度达到了保证地面建(构)筑物安全的要求。
combining with a actual example,interrelated technology of grouting on fragmentized goaf groundwork had been researched and actualized.The area should be grouted had been draw,and the position of drill,the same as proportion of material been transfused and techniques should be used had been draw also.The result got from drill designed for checking up showed that the purpose of practice in according with which designed,and the intensity of groundwork been treated will keep the building up safe.
