【摘要】 地下水患是井筒掘进施工中最大的技术难题之一。石灰岩层水文地质特征复杂多变，赋水状况无规律可寻，极易造成突水事故，延误工期、影响工程质量，危及人员安全。本文结合铧子石膏矿井筒石灰岩层突水进行了理论与应用技术研究，系统分析了突水对施工的影响与危害，在研究了石灰岩层水文及突水特征的基础上，制定了综合治水方案，进行了室内试验和现场实验，对止浆垫的设计和施工进行了较深入的研究，尤其解决了超深水下灌注混凝土这一前沿性的技术难题，研究了水(泥浆)下混凝土的流动规律及水下灌注混凝土的质量变异，研究了注浆材料及注浆过程检测技术，综合治水达到了预期的目标，取得了显著的经济、技术和社会效益，为相关类似工程的建设和施工提供了有价值的参考经验。更多还原

【Abstract】 The underground flood is one of the biggest technological difficult problems while constructing the pit shaft tunnels. The hydrogeological characteristic in lime rock stratum is complicated and changeable and have no law to seek about the composing water state, so it is extremely apt to cause dashing for ward water accident, delay time limit for a project, influence project quality, and threaten the security of personnel. This text combine Ore pit shaft with sub gypsum of ploughshare and lime rock stratum dash for ward to go on the theory and application technical research, and analyze the influence and danger systematically which dashing for ward water enforce in constructing. On the basis of studying lime rock stratum hydrology and dashing for ward water characteristic, it has made the scheme of administrate underground flood, had carried on the indoor test and on-the-spot experiment, has carried on deeper research to design and construct the cushion which stopping the thick liquid. Especially has solved the front technological difficult problem which pours into the concrete under exceed the deep water. It has study the flow law of laying the concrete and the variation quality of pouring into the concrete under water (mud). And it has study the detection technique in material and course of pouring into the concrete that made the administrating underground flood reach the anticipated goal, This text has make remarkable economy, technology and social benefit, and has offered valuable reference experience for the relevant construction and construction which are similar to the project.更多还原
