上下分体装配式预制管廊施工技术

Construction of Precast Utility Tunnel with Upper and Lower Assembly

现浇施工作为传统施工工法,在城市管廊建设中逐步暴露出不足之处,使我们不得不对管廊的施工进行研究和改进。在工厂预先制成管廊构件产品,有效控制质量,具有施工效率高、工期短等优势,弥补了许多传统现浇施工的不足。对六盘水地下综合管廊项目上下分体装配式预制管廊施工技术进行了详细介绍,主要包括预制管廊结构设计方案、预制管廊生产及安装。

As a traditional construction method, cast-in-place construction has gradually exposed its shortcomings in the construction of utility tunnel, so that it has to study and improve its construction. The product of utility tunnel component made in advance can effectively control quality, and has the advantages of high construction efficiency, short construction period and so on, so that it can make up for many shortcomings of traditional cast-in-place construction. Based on the background of Liupanshui underground utility tunnel project, the upper and lower assembly construction is introduced in detail, which mainly include /he structural design scheme of utility tunnel, precast components production and installation.
