Road semi-rigid base layer crack chemical treatment method
The invention relates to the technical field of crack treatment, and discloses a road semi-rigid base layer crack chemical treatment method which comprises the following steps: cleaning a crack, cleaning a treated road section, removing a crack pouring material for daily maintenance, blowing the crack by adopting a high-pressure air gun, removing impurities in the crack, and cleaning the crack by adopting a high-pressure air gun, and marking crack positions on the outer sides of the road shoulder plates, the guardrail plates and the outer sides of the stand columns in a classified mode. According to the road semi-rigid base layer crack chemical treatment method, drilling is conducted, hole sites are carefully checked before drilling, an electric hammer drill rod is vertically aligned with the hole sites during drilling, drilling is conducted slowly at a constant speed till the drilling depth meets the design requirements (the filling and soil excavation section is 70 cm, the stone excavation section is 48 cm, and the interchange zone ramp is 58 cm), and drilling is completed, a broom and an air blower are used for cleaning a drilled hole in time, a lower pipe is used for grouting, and the pipe goes down from a grouting hole, so that the damage to the road surface is small, traffic can be quickly recovered, and the treatment effect is good.
本发明涉及裂缝处治技术领域，且公开了一种道路半刚性基层裂缝化学处治方法，包括以下步骤，清理缝隙，将处治路段清扫干净，清除日常养护的灌缝材料，采用高压气枪将裂缝吹干净，并清除裂缝内的杂物，在路肩板、护栏板外侧及立柱外侧分类标记裂缝的位置。该道路半刚性基层裂缝化学处治方法，通过钻孔，钻孔前再仔细检查孔位，钻孔时使电锤钻杆垂直对准孔位，开钻匀速慢进的钻进，直到钻孔深度达到设计要求(填方及土质挖方段为70cm，石质挖方段为48cm，互通区匝道为58cm)，钻孔完毕，使用扫帚和吹风机及时对钻孔处进行清理，下管注浆，管通过从注浆孔下入，本方法对路面破坏小，可以快速恢复交通，处治效果较好。
