Shield tail brush replacement construction method for water-rich soft sensitive stratum
The invention discloses a shield tail brush replacement construction method for a water-rich soft sensitive stratum, and belongs to the technical field of tunnel construction. According to the construction method, the MJS construction method piles are constructed in a selected operation area on the ground for stratum pre-reinforcement; after reinforcement is completed, the strength and the permeability coefficient of a reinforcement body are detected through core pulling, the shield tunneling machine is tunneled to a designated position after the requirements are met, and then further water stopping operation is conducted through a segment separated from a shield tail and a water stopping ring; and after water stopping operation is completed, the shield tail first ring duct pieces are dismantled one by one, then shield tail brush replacement operation is carried out, duct piece assembly is recovered after replacement is completed, shield tail grease is injected into a shield tail grease cavity, and normal tunneling is recovered. According to the shield tail brush replacement construction method for the water-rich soft sensitive stratum, the safety of shield tail brush replacement operation of a shield tunneling machine in the water-rich soft sensitive stratum is effectively ensured.
本发明公开了一种用于富水软弱敏感地层的盾尾刷更换施工方法，属于隧道施工技术领域。本发明的施工方法，在地面选定作业区域施做MJS工法桩进行地层预加固；加固完成后，通过抽芯对加固体强度和渗透系数进行检测，满足要求后将盾构机掘进至指定位置，随后通过脱出盾尾的管片并施做止水环进行进一步止水作业；止水作业完成后，逐块拆除盾尾第一环管片，随后进行盾尾刷更换作业，更换完成后恢复管片拼装，在盾尾油脂腔注入盾尾油脂，恢复正常掘进。本发明的用于富水软弱敏感地层的盾尾刷更换施工方法，有效地确保了盾构机在富水软弱敏感地层更换盾尾刷作业的安全。
