Open excavation hidden roof construction method for large-pipe-diameter reinforced concrete pipeline
The invention discloses a large-pipe-diameter reinforced concrete pipeline open excavation and hidden roof construction method which comprises the steps of open excavation of a foundation pit, installation of jacking equipment, jacking of a pipeline, backfilling of the foundation pit, pipeline grouting and the like, open excavation and hidden roof are combined for construction, an excavator open excavation process is used for detecting underground pipelines and structures along the way, a hydraulic jack hidden roof pipeline process is adopted, and a large-pipe-diameter reinforced concrete pipeline is constructed. The pipeline is ingeniously used as a foundation pit wall support, the excavation distance is short, and the construction cost is greatly reduced. The upper part of the pipeline is mechanically excavated, the lower part of the pipeline is manually repaired and leveled, the upper part and the lower part are simultaneously performed, the efficiency is high, excavated earthwork is excavated and pulled at the same time, the project progress is accelerated, and the construction period is shortened.
本发明公开了一种大管径钢筋混凝土管道明挖暗顶施工方法，包括明挖基坑、安装顶进设备、顶进管道、基坑回填、管道注浆等步骤，明挖+暗顶相结合进行施工，利用挖掘机明挖工艺探明沿途地下管线及构筑物，采用液压千斤顶暗顶管道工艺，巧妙借助管道自身作为基坑壁支护，挖掘距离较短，施工成本大大降低。管道上部采用机械开挖，管道下部采用人工修缮平整，上下同时进行，效率高，挖掘的土方随挖随拉，加快了工程进度，缩短了工期。
