摘要
通州文化旅游区云瑞南街西段综合管廊工程矿山法施工段斜交近距下穿南水北调通州支线1 800输水管道,对施工沉降控制要求极高,结合支护长度,采用跟管钻进大管棚中间搭接的方式进行支护,研究管棚搭接施工方法、精度和沉降控制措施,总结在沉降指标要求严格下的管棚搭接施工方法和控制措施。
The mining construction segment of comprehensive pipe gallery project along the west part of Yunrui South Street in Tongzhou Culture and Tourism Area passes through under the 1800 water pipe of South-to-North water diversion line,having high requirements for the control of construction settlement.Based on the supporting length,big tubular shed overlapping was adopted as supporting structure.This paper studied the tubular shed overlapping construction method and measures for accuracy control and settlement control,and summarized a set of construction methods and control measures for tubular shed overlapping under strict settlement requirements.
