改良型阿特拉斯钻机在宁波轨道交通的实践应用研究

Practical Application of Improved Atlas Drilling Rig in Ningbo Rail Transit

轨道交通工程建设涉及众多管线,在轨道交通工程建设过程中如何确保管线运行安全,一直是工程界面对的棘手难题。以宁波轨道交通4号线双东路站北端头加固为背景,在施工场地狭义以及燃气、雨水、污水等市政管线无法迁改的前提下,应用改良型阿特拉斯钻机进行土体加固,最大限度地减少了管线周边土体的扰动,保证了管线运行安全。

The construction of rail transit project involves many pipelines.How to ensure the safety of pipeline operation in the construction process of rail transit project has always been a difficult problem for the engineering interface. Taking the reinforcement of the north end of Shuangdong Road Station of Ningbo Rail Transit Line 4 as the background,under the premise that the construction site is narrow and the municipal pipelines such as gas,rainwater and sewage can not be changed,the improved Atlas rig is applied to reinforce the soil,which minimizes the disturbance of the soil around the pipeline and ensures the safe operation of the pipeline.
