摘要
根据北京南站十四号线南站预留工程区间过泵房段地质特点及工程概况,拟定了区间过泵房段施工方案设计,重点介绍了深孔注浆的设计及施工要点,证实了在卵石层中矿山法施工时深孔注浆预加固地层的有效性,为今后类似工程积累了经验。
Based on the geological characteristics and the engineering situation of the reservation engineering interval section of the south station of the fourteen line pass bythe interval pump house in Beijing southern station, the author makes the construction designing scheme of the interval section pass by the pump house, mainly introduces the design and the construction points of the deep hole grouting, confirmes the effectiveness Of the deep hole grouting pre-strengthening of the ground in the construction of the cobble layer by using the mining method, which accumulates the experience for the similar projects.
