Road repair grouting method
The invention discloses a road repair grouting method in the field of road maintenance. The road repair grouting method comprises the following steps that S1, construction preparation is conducted; S2, paying off and positioning are carried out; S3, drilling is conducted; S4, pipe burying is conducted; specifically, a grouting pipe is inserted into a grouting hole, and after the grouting pipe reaches the hole distribution depth, a remaining gun head is inserted into the grouting hole and seals the grouting hole; S5, carrying out pulping; S6, grouting is conducted; specifically, the prepared grout is injected into the grouting pipe through the remaining gun head, high-pressure grouting is conducted according to 2-3 times of the grouting pressure at the beginning of grouting, grouting is conducted according to the designed grouting pressure after 2-3 s, and grouting is stopped when the grouting stopping condition is met; and S7, pipe drawing is carried out. According to the road repair grouting method, the grouting efficiency is improved, the road repair effect is improved, grout overflowing is greatly reduced, the road repair effect is improved; and meanwhile, cleaning work after road repair is relieved.
本发明公开了道路维修养护领域内的一种道路修复注浆方法。该种道路修复注浆方法包括以下步骤：S1施工准备；S2放线定位；S3钻孔；S4埋管：将注浆管插入注浆孔，到达布孔深度后，将留置枪头插入注浆孔内并封闭注浆孔；S5制浆；S6注浆：将制备好的浆液通过留置枪头注入注浆管内，注浆初始时按注浆压力的2～3倍的高压注浆，2～3s后按设计的注浆压力注浆，当满足停浆条件时终止注浆；S7拔管。该种道路修复注浆方法通过上述方式提升注浆效率、提高道路修复效果、大幅减少浆液外溢、提高道路修复效果，同时减轻对道路修复后的清理工作。
