【摘要】 介绍了一种极恶劣情况下,为防水害和垮井事故发生而研究的特殊的破井壁超前加固技术。该技术综合应用了材料力学、弹塑性力学、混凝土学、钢骨混凝土理论等,其最大的特点在于井壁的开挖位于加固之后,即使用超前加固方法在井壁上开设一个大直径通风口。该技术方法为钻井法施工的井筒在极恶劣环境下通过破壁增开通风道提供了一种极为安全的技术方法,对我国上世纪80年代期间建造的钻井井筒具有很大的参考价值。更多还原

【Abstract】 This paper introduces a special advanced reinforcement technology for the breaking shaft in an extremely disgusting circumstances in order to prevent water damage and collapse shaft collapsing.In this research,materials mechanics,elastic-plastic mechanics,concrete places,such as steel reinforced concrete theory are applied.The greatest feature of this technology is that breaking shaft is located after the reinforcement,that is,an advanced reinforcement method is used to open a large-diameter ventilation hole.For setting a ventilation tunnel in an extremely disgusting circumstances,the techniques researched in this paper provides a very safe technique method for the shaft constructed by drilling method.The research result plays a significant role in drilling shaft constructed during the eighties of the last century.更多还原
