摘要
盐田隧道洞口段围岩条件不良,地下水丰富,隧道开挖进洞施工难度较大。结合工程实际与施工技术经验,确定采用井点法降水,并相应制定井点的布置与构造、成孔工艺、降水管理、降水监测、应急措施等内容。经施工实践证明,采用该方法进行降水,效果明显,有效保证隧道施工的顺利进洞。
Due to the unfavorable condition of the surrounding rock of Yantian tunnel and the rich groundwater, the tunnel excavation becomes more difficult. Combined with the engineering practice and construction technical experience, the method of well point drainage was applied and the corresponding layout and structure, well point hole forming process, precipitation, and precipitation monitoring content management were also set. The construction practice proves that the method of well point drainage is effective and has successfully guaranteed the construction of the tunnel.
