Deep hole grouting method
The invention relates to the technical field of grouting, in particular to a deep hole grouting method which comprises the following steps that S1, a grouting area is determined, and laying of grouting holes is completed; two grouting pipes and a discharge pipe are preset in the grouting hole, the grouting pipes input grout into the grouting hole, and the discharge pipe is used for discharging water and gas in the grouting hole and returning grout; s2, grouting the bottom of the grouting hole from one grouting pipe, ventilating and pressurizing the grouting hole from the other grouting pipe at the same time, discharging water in the grouting hole from a drain pipe, and grouting the grouting hole by the two grouting pipes when grouting to a certain position in the grouting hole; and S3, grouting is continued until dense slurry is discharged from the discharge pipe, then grouting of the two grouting pipes is stopped, pipe openings are closed, grouting is completed, drainage in the deep hole is easier, the deep hole is not affected by the depth and width of the grouting hole, and the grouting effect is better.
本发明涉及灌浆技术领域，具体涉及一种深孔灌浆方法，包括以下步骤：S1：确定灌浆区域，并完成灌浆孔的布设；灌浆孔内预设两个灌浆管和排泄管，灌浆管向灌浆孔内输入浆液，排泄管用作排出灌浆孔内的水、气，以及回浆；S2：从其中一个灌浆管往灌浆孔底注浆，同时从另一个灌浆管往灌浆孔里通风加压，使灌浆孔里的水从排泄管排出，灌浆到灌浆孔内一段位置时，两个灌浆管均往灌浆孔注浆；S3：持续注浆，直到看到排泄管有浓浆排出，然后停止两个灌浆管的注浆，并将管口封闭，灌浆完成，使深孔中排水更容易，不受灌浆孔深度和宽度的影响，灌浆效果更好。
