大瑞铁路大柱山隧道燕子窝断层集高压富水、大型岩溶、超长断层、异常破碎等特点于一体，采用常规注浆工艺已无法通过，经长期多方案比选，最终采用“远排近堵，超高压分段聚合注浆”工艺施工，得以安全顺利通过。
大瑞鐵路大柱山隧道燕子窩斷層集高壓富水、大型巖溶、超長斷層、異常破碎等特點于一體，採用常規註漿工藝已無法通過，經長期多方案比選，最終採用“遠排近堵，超高壓分段聚閤註漿”工藝施工，得以安全順利通過。
대서철로대주산수도연자와단층집고압부수、대형암용、초장단층、이상파쇄등특점우일체，채용상규주장공예이무법통과，경장기다방안비선，최종채용“원배근도，초고압분단취합주장”공예시공，득이안전순리통과。
Darui railway Dazhushan tunnel Yanziwo fault sets the high-pressure water-rich, large karst, long fault and broken abnormal features in one, so the use of conventional grouting technology is not suitable. Through the comparison of multi-program in long term, the construction technology of "outside-drainage and inside-plugging and ultrahigh pressure section grouting" is finally adopted and succeeded.
