Treatment method for void cracking of stone-filled roadbed
The invention discloses a treatment method for void cracking of a rock-filled roadbed, and relates to the technical field of road maintenance. The method comprises the steps that pipe-following drilling is adopted in the drilling process of the gravel layer; when filling grout is poured, if a large amount of grout leaks out of the void cracking position of the rock-filled roadbed in the grouting process, the measure of intermittent grouting or pump quantity reduction should be adopted to prevent a large amount of grout from losing from the ground. According to the method, related information of void cracking of the rock-filled roadbed can be fully obtained by using a nondestructive testing technology, subsequent drilling of grouting holes is guided to facilitate reliable repair, and when the void cracking position of the rock-filled roadbed is treated by setting detection, hole opening and filler pouring, the void cracking position is detected firstly, then a drill hole is formed, and the detection accuracy is improved. According to the method, the filler is poured into the void cracking position in the rock-filled roadbed through the drill hole, the situation that the pavement structure needs to be damaged is reduced, and therefore the situation that traffic is affected when void cracking is treated is reduced.
本发明公开了一种填石路基脱空开裂的处治方法，涉及公路养护技术领域。本发明包括在砾石层的钻探过程中采用跟管钻进；灌注填充浆液时，注浆过程中若出现填石路基脱空开裂处大量跑浆时，应采用间歇式注浆或减小泵量的措施，阻止浆液从地面大量流失。本发明通过使用无损检测技术，能够充分获取填石路基脱空开裂的相关信息，指导后续钻注浆孔有利于实现可靠修复，通过设置检测、开孔和灌注填充物，在对填石路基的脱空开裂位置进行处治时，先对脱空开裂处进行检测，然后开设钻孔，通过钻孔向填石路基中脱空开裂处进行灌注填充物，减少了需要对路面结构进行破坏的情况发生，从而减少了对脱空开裂进行处治时影响交通的情况。
