象山隧道4号斜井复杂溶岩区段注浆加固堵水技术研究

Research on Grouting Technology in Krast section In No.4 Inclined Shaft of Xiangshan Tunnel

首先介绍了龙厦铁路象山隧道4号斜井岩溶区段工程地质和水文地质情况,结合现场进行了现场试验,以左线DK30+026～+056段的注浆循环为例,在注浆参数、材料选用、注浆顺序、施工工艺、机具设备配置以及注浆效果评定等方面,对岩溶地段全断面超前注浆加固技术做了介绍,为今后类似工程积累了经验。

The engineering geology and hydro--geology of the karst section of Xiangshan tunnel on Longyan--Xiamen railway is presented. The full--face advance grouting technology for karst area, including grouting parameters, grouting materials, grouting procedure, grouting technique, grouting equipment and grouting effect assessment are described, with the grouting in DK30＋026-- ＋056 section of Xiangshan tunnel as an example. This paper can provide reference for similar projects in the future.
