摘　　要：受成本、工期、条件等因素限制,微型盾构工程往往不具备充分的空间设置始发井和接收井。通过对狭小工作井内盾构半环分体始发、盾构分体接收的研究,解决了工作井尺寸不满足盾构整体始发、接收需求的问题,保证盾构施工按照计划节点顺利、安全始发、接收。总结的经验可供类似工程参考。Limited by cost, construction period, conditions and other factors, micro shield projects often do not have enough space to set the launching shaft and receiving shaft. Through the research on the semi ring split launching and split receiving of shield in the narrow working shaft, the problem that the size of the working shaft does not meet the overall launching and receiving needs of the shield has been solved, and the shield construction can be smoothly and safely launched and received according to the planned nodes. The summarized experience can be used as reference for similar projects.
