预埋技术在城市地铁工程建设中的应用与推广
|
摘要
地铁隧道内要悬挂多种管线、接触网和疏散平台等构件,国内自从建地铁以来,一直采用传统的打孔植筋技术,即用打孔机在隧道的主体结构上打孔,再安装支架固定管线。这种传统的方法会对主体结构造成永久性的和不可逆的破坏,严重影响隧道的使用寿命。因此,急需寻找替代方案以克服传统方法的缺陷。以深圳地铁9号线盾构区间为实例,介绍了预埋技术在城市地铁领域内的成功应用及在全国范围内的推广。
In the subway tunnel,varieties of components are required to be installed after tunnel structure is completed,including pipelines,OCS,evacuation platforms etc. Since the construction of the subway in our country,the traditional method of drilling-hole and planting-bolt has always been used for the components installation. Drilling machine is used to bore holes on the main structure of the tunnel,then to install the bracket in holes to fix the components. This traditional method causes permanent and irreversible damage to the tunnel main structure,which seriously affects the service life of the tunnel. Therefore,there is an urgent need to find alternatives to overcome the shortcomings of traditional method. Taking the shield tunnel of Shenzhen Metro Line 9 as an example,the successful application of pre-embedded technology in the field of urban subway and its promotion nationwide are introduced.
