Rapid and accurate grouting repair process for road base cavity diseases
The invention discloses a rapid and accurate grouting repair process for road base cavity diseases, and belongs to the technical field of road cavity disease repair. The method comprises the following steps: S1, determining the position and size of a base layer cavity disease, the size of an elastic balloon and the predicted dosage of a grouting repair material through a ground penetrating radar nondestructive testing technology; s2, grouting holes are formed in the upper portion of the base layer cavity damage; s3, the elastic balloon is placed in the base layer cavity disease through the grouting hole; s4, a grouting repair material is injected into the elastic balloon, and the grouting pressure is monitored; and S5, when the grouting pressure rapidly rises, grouting is stopped. According to the process, on one hand, the slurry flowing range can be accurately controlled to fill holes, so that slurry cannot flow to other areas along existing cracks; on the other hand, it can be guaranteed that the grouting repair material is tightly attached to the inner surface of the cavity, and the cavity is fully filled. The technical problems that in an existing method, bumps are easily formed, even a surface layer is jacked up, and secondary damage to a road is caused are solved.
本发明公开了一种道路基层空洞病害快速精准注浆修复工艺，属于道路空洞病害修复技术领域。其包括以下步骤：S1：通过探地雷达无损检测技术，确定基层空洞病害的位置和尺寸、弹性球囊的尺寸和注浆修复材料的预计用量；S2：在基层空洞病害的上方开设注浆孔；S3：将弹性球囊通过注浆孔放置在基层空洞病害内；S4：向弹性球囊内注入注浆修复材料，监测注浆压力；S5：当注浆压力迅速上升时，停止注浆。该工艺一方面可以精准控制浆液流动范围填充空洞，使得浆液不会沿既有裂缝流向其他区域；另一方面，能保证注浆修复材料与空洞内表面紧密贴合，充分填充空洞。解决了现有方法存在的容易形成鼓包，甚至将面层顶起，造成对道路的二次破坏的技术问题。
