摘　　要：为有效提升装配式综合管廊工程的施工质量,以北京市万盛南街-曹园南大街的地下综合管廊工程为例,研究一种装配式综合管廊全机械化拼装施工技术.施工前先浇筑混凝土以确保基础平整,安装导轨以确保构件移动精确;构件配备定位装置和调节杆,实现垂直校正;利用拼装系统和吊装轴,机械化完成构件安装;进行灌浆和防水处理,满足要求后回填土方.测试结果表明:运用该技术完成全机械化拼装施工后,装配式综合管廊多个构件的轴线偏差在10 mm以内,可以提高拼装施工的工程质量.The objective of this study is to identify effective methods for enhancing the quality of prefabricated comprehensive pipe gallery construction projects.To this end,a comprehensive analysis is conducted on the potential benefits of fully mechanized assembly construction technology for prefabricated comprehensive pipe galleries.The underground comprehensive pipe gallery project from Wansheng South Street to Caoyuan South Street in Beijing is selected as a case study to illustrate the feasibility and potential outcomes of this technology in a real-world context.It is recommended that concrete be poured prior to construction in order to ensure the creation of a smooth foundation.Additionally,the installation of guide rails is advised in order to guarantee the precise movement of components.The components are equipped with positioning devices and adjustment rods,which facilitate the achievement of vertical correction.The installation of the components should be carried out using mechanical assembly systems and lifting shafts.Subsequently,the application of grout and waterproofing treatments should be undertaken,and the soil should be backfilled once the requisite conditions have been met.The test results demonstrate that the newly proposed technology,when employed for the fully mechanized assembly construction,results in a maximum axis deviation of 10mm for multiple components in the prefabricated comprehensive pipe gallery.It is evident that this improvement in engineering quality of assembly construction is a significant advancement.
