湖南旺旺医院(二期)深基坑出土施工技术

Excavation Construction Technology for Deep Foundation Excavation in Hunan Want Want Hospital (the Second Phase)

针对传统深基坑出土模式出土困难和效率不高的问题,以湖南旺旺医院(二期)为工程背景,在参考传统出土模式的基础上,采用新型深基坑出土施工技术。该技术有效解决在逆作法岩土方施工中垂直运输问题,能有效降低土石方出土成本,实现土石方白天、晚上同时作业,提高出土功效、加快施工速度从而缩短工期。该技术实用、安全可靠、操作性强,社会效益和经济效益明显,具有推广价值。

In view of the difficulty and low efficiency for deep foundation excavation with traditional excavation mode,relying on the project of Hunan Want Want Hospital (the second phase),a new excavation construction technology is adopted on the basis of traditional excavation mode. This technology can effectively solve the problem of vertical transportation. It can effectively reduce the cost of earth and stone excavation,realize the simultaneous operation of earthwork in the daytime and at night,improve the efficiency of excavation,accelerate the construction speed,and shorten the construction period. The technology is practical,safe and reliable,with strong operability,has obvious social and economic benefits,and is worth popularizing.
