在重大工程施工过程中,因受工程场地局限、工程材料管理和运输成本费用高以及成品保护难度大等问题的影响,在工程现场或工程场地附近进行成品加工和预制,减少了工程运行的环节,提高了工程效益,节约了工程成本,本文以南宁市轨道交通1号线一期工程南湖站、金湖广场站顶管施工工程为例,论述了顶管现场预制的各个环节和质量控制要素,确保了工程质量。 During the construction of major projects, the processing and prefabrication of finished products are carried out near the project site or project site due to the limitation of project site, the high cost of project material management and transportation costs and the difficulty of finished product protection, which reduces the operation of the project , To improve the project efficiency and save the project cost. This paper takes the construction of the pipe jacking of Nanhu Station and Jinhu Square Station of Nanning Metro Line 1 as an example, and discusses the various aspects of on-site precasting and quality control elements , To ensure the quality of the project.
