摘要：【中文】本发明公开了一种基于膨胀土渠坡裂缝的贴嘴式灌浆施工方法，通过选取试验段、清理裂缝、初步封堵缝隙、预置灌浆管、准备灌浆材料、制备浆液、灌注浆液及取芯等一系列步骤，完成对渠坡裂缝的灌浆施工。与现有技术相比，本发明采用的技术方案表明路面以下90‑115cm范围内土体填筑密实、裂缝宽，含水率低，此时采用地面贴嘴式灌浆，仅挖除沥青路面，灌浆效果较好，不仅能有效封堵渠坡的裂缝，而且能保持较长时间不再有裂缝。 【EN】The invention discloses a nozzle-attaching grouting construction method based on expansive soil channel slope cracks, which completes grouting construction of channel slope cracks through a series of steps of selecting a test section, cleaning cracks, primarily plugging the cracks, presetting a grouting pipe, preparing a grouting material, preparing slurry, pouring the slurry, coring and the like. Compared with the prior art, the technical scheme adopted by the invention shows that the soil body within the range of 90-115cm below the road surface is densely filled, has wide cracks and low water content, and at the moment, the nozzle-attached grouting is adopted, only the asphalt road surface is dug, the grouting effect is better, the cracks of the channel slope can be effectively blocked, and the cracks can be kept for a longer time without any more.
