Background
Loose or broken rock mass is often an important dangerous source for geotechnical engineering safety, and the rock mass is usually reinforced and the mechanical property of the rock mass is improved by adopting a grouting method, so that the safety of the geotechnical engineering is further ensured. In engineering practice, the grouting can be generally divided into 2 types of forward type and backward type according to the relative sequence of grouting; according to the grouting pressure, normal pressure grouting and high pressure grouting can be divided. When a high-pressure retreating type grouting method is adopted in a loose or broken rock body, the inevitable high-pressure slurry bypasses a hole packer to return slurry (namely commonly called a 'back-copying path') through loose bodies outside a grouting hole, so that the hole packer is locked and is difficult to pull out, the hole packer is scrapped and lost, and the later-stage circular grouting quality is difficult to ensure. Particularly, the above problem is more serious if the grouting material is cement-water glass double-liquid quick setting slurry.
The main symptoms that lead to loss of closure of the packer are two: firstly, because grouting belongs to hidden engineering, whether the grout returns to the rear side of a hole packer cannot be predicted; secondly, even if the 'back line' of the slurry is known, if the slurry is not cleaned in time, the pressure relief time of the hole packer is long, and the slurry is solidified and is difficult to pull out. At present, no good solution is available, loss can be reduced as much as possible only by experience in the construction process, the practical application of high-pressure retreating type grouting is limited to a certain extent, and the grouting method has irreplaceable advantages when used in specific projects.
