摘要
针对传统加固方式难以保证盾构的顺利始发和接收问题,通过对地质条件进行分析,对加固区进行计算,最终确定采用高压旋喷桩和地面袖阀管压密注浆联合加固技术,加固砂层,在富水软弱地层起到了很好的止水效果,从后期取芯验证,加固效果良好,确保了土体稳定,保证了盾构机顺利接收。
It is difficult to ensure the smooth start and reception of shields.After the analysis of thegeological conditions,compaction grouting combined with reinforcement technology are used to reinforcesand layer.A very good water-stop effect is achieved in the water-rich soft soil layer.From the late coreverification,one knows that reinforcement effect is good.It can ensure the stability of the soil and thesmooth reception of shield machine.
