综合管廊下出线节点施工技术研究与应用

Construction Research and Application of the Lower Outlet Point of Comprehensive Utility Tunnel

管廊节点作为管廊整体的一个重要组成部分,在管廊系统中扮演管线的"十字路口"角色。其中节点主要分为上出线节点和下出线节点。六盘水地下综合管廊主要采用下出线节点的结构形式。重点介绍了管廊下出线节点的关键施工技术。以突出下出线节点的施工重难点为主线,主要从主体结构施工、施工细部处理以及机电工程施工等3方面来对下出线节点施工技术做详细描述。

As an important part in utility tunnel, the joints play the role of pipeline crossroad, which include the upper outlet joints and lower outlet joints. Liupanshui underground comprehensive utility tunnel mainly applies the lower outlet joint. This paper mainly introduces the key construction technology of the lower outlet joint. In order to highlight the construction of the lower outlet joint as the main line, mainly includes the main structure construction, construction details and electromechanical engineering construction to do a detailed description.
