摘要
排水箱涵由于施工质量、运输车辆重型化、使用年限增加等原因常常发生渗漏,结合非开挖修复排水箱渠的工程实例,分析了渗漏原因、注浆堵漏的技术难点等。总结出适用的注浆堵漏方式、注浆堵漏材料和压力,可为在复杂施工条件和不良土层地质条件下的箱涵修复提供借鉴。
Aiming at the leakage phenomenon of drainage culvert due to construction quality problems,heavy transport vehicles and increased service life,the causes of leakage and the technical difficulties of grouting plugging were studied in combination with the engineering example of drainage culvert trenchless repair.The applicable grouting plugging methods,grouting plugging materials and pressures are summarized,which could provide reference for culvert repair under complex construction conditions and poor soil geological conditions.
