摘要
暗挖施工通常采用“竖井+横通道+正线隧道”的施工方法,北京市通州区某综合管廊工程将暗挖横通道与临时施工竖井合二为一,采用倒挂井壁法施工横通道。既有助于缩短管廊暗挖施工周期,并为后续廊内机电安装设备、材料的进出创造了空间,有效的缓解了管廊工期压力。
Underground excavated construction usually adopts construction method of"shaft+horizontal passage+main line tunnel".A comprehensive pipe gallery project in Tongzhou District,Beijing combines underground excavated transverse passage with temporary construction shaft,and adopts the inverted shaft wall method to construct horizontal passage,which not only helps to shorten construction period of underground excavation of the pipe gallery,but also creates space for entry and exit of mechanical and electrical installation equipment and materials in subsequent gallery and effectively relieves pressure of pipe gallery construction period.
