Study on Segmented Grouting and Consolidation Technology of Borehole Orifice Pipe for Water Exploration and Drainage

The quality of grouting and consolidation orifice pipe in water exploration drainage drilling is directly related to whether a large amount from holes can be successfully controlled. For with fissure within 3 m holes, difficult point drainage. By studying the principle segmented technology, casing installation construction technology technical parameters plugging, we have solved problem under condition water. In field, adopted, which divided into two sections. first section solves hole fixing half pipe, second plugging fixing. After by above method, injection pressure test passed. results show that method effectively solve fixation
