Tapered grouting construction method based on longitudinal crack of swelling earth channel slope
The invention discloses a tapered grouting construction method based on a swelling earth channel slope crack. The grouting construction of the channel slope crack is completed in a series of steps ofselecting a test section, cleaning the crack, preliminarily blocking the crack, presetting a grout pipe, preparing grouting materials, preparing grout, grouting and coring.Compared with the prior art,the tapered grouting construction method of the technical scheme has the advantages that the soil filling within the range of 90 to 115 cm below a road surface is compact, the crack is wide, the moisture content is low, when the ground tapered grouting method is adopted at the moment, only the asphalt road surface is excavated, the grouting effect is good, the channel slope crack can be effectively blocked, and no cracks can be kept for a long time.
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。
