Grouting construction method and device suitable for wall protection and leaking stoppage of fractured formation drilling engineering
The invention discloses a grouting construction method suitable for wall protection and leakage stoppage of fractured formation drilling engineering. The grouting construction method comprises the following steps that S1, the water leakage position of a foundation pit is measured and positioned, and a grouting hole position is arranged; s2, a geological drilling rig is adopted for drilling holes, the drilled holes penetrate through the fractured stratum to enter the impervious layer, the entering depth exceeds two meters, grouting pipes are inserted into the drilled holes and inserted into the bottoms of the holes, and the inner walls of the grouting pipes are washed with water; s3, single-liquid slurry or double-liquid slurry is selected for plugging according to the size of cracks in the hole, according to the technical scheme, the components and the proportion of the slurry are replaced and adjusted, a set of operation system suitable for broken stratum drilling wall protection plugging is formed, the broken stratum wall protection quality and the drilling efficiency are effectively improved, and the drilling cost is reduced. And accurate first-hand information is provided for detection and treatment of the copper mine goaf.
本发明公开了一种适用于破碎地层钻探工程护壁堵漏的注浆施工方法，其包括以下步骤：S1、对基坑漏水处进行测量定位，设置注浆孔位；S2、采用地质钻机钻孔，且钻孔穿过破碎地层进入不透水层，进入深度超过两米，在钻孔内插入注浆管并插入到孔底，采用水冲洗注浆管的内壁；S3、根据孔内裂隙大小，选择单液浆或双液浆等等进行封堵，本发明技术方案更换调整泥浆的成分和比例，形成了一套适合破碎地层钻孔护壁堵漏的作业体系，有效地提高了破碎岩层护壁质量以及钻进效率，为铜矿空区探测及治理提供了较准确的第一手资料。
