竖井突涌水淹井处理技术研究与应用
|
摘要
为妥善处理深大竖井由于地质复杂、地下水发育且补给足而快或开挖施工方法不当、技术及管理措施不到位等因素所致的突涌水淹井事故,以大瑞铁路高黎贡山隧道1~#竖井副井突涌水淹井为工程案例,详细介绍如何用静水压注改性水泥浆垫封水法处理深竖井淹井事故,并提出一套适用于工期紧、淹井深、地质复杂、水源补给足而快等条件下的淹井处理参数,为水深超过600 m的淹井处理提供经验借鉴。
In order to properly handle the water inrush and flooding accidents caused by complicated geology,rapid groundwater development with excessive recharging, improper excavation and construction methods, inadequate technology and management measures,this paper takes the inrush and flooding at the auxiliary shaft in the 1# shaft of Gaoligongshan Tunnel of Darui Railway as an example,and introduces the water sealing method with modified cement slurry under hydrostatic pressure in detail,which is used to deal with flooding accidents. A set of parameters apply to the cases such as tight construction period,deep flooding,complex geology,excessive and fast water supply are put forward,which can provide reference for the flooding treatment with water depth exceeding 600 meters.
