东山供水工程小断面土质引水隧洞施工技术

On the Technique to Construct a Small Section Water Supply Tunnel in Soil Stratum of the Dongshan Water Supply Project

小断面土质引水隧洞在施工时难以实现大型机械操作,如何高效、安全和快捷地完成施工任务,技术的实际应用和设备的选用是关键。文中以东山供水工程十六标隧洞为例,对小断面土质引水隧洞施工特点和难点进行分析,并针对本工程的情况,提出一些相应措施。

During constructing the small section water srpply tunnel in soil stratum,it is difficult to realize using and operating of the large-sized construction machnie. The actual use of technique and the selection of equipment are the key points on how to high-effectively,safely and speedily complete the construction task. Taking the 16 th tender section tunnel in the Dongshan Water Supply Project as an example,the paper analyzes the feature and difficulty points for constructing the small section water supply tunnel in the soil stratum and being aimed at this project＇s situation,presents some corresponding measures.
