Shield interval collinear close-distance underneath-penetrating open cut tunnel under construction construction method
The invention relates to a shield interval collinear close-distance underneath-crossing open-cut tunnel under construction construction method, and belongs to the technical field of building construction, and the method comprises the following steps: S1, before shield underneath-crossing open-cut tunnel under construction, condition checking passes acceptance inspection, the position relation between the open-cut tunnel under construction and an interval tunnel and the geological condition of an underneath-crossing section are fully understood, and the underneath-crossing section is determined; a reliable construction scheme is formulated according to design requirements; s2, before the shield tunneling machine formally passes through the open cut tunnel under construction, the shield tunneling machine needs to be systematically and comprehensively checked and maintained once; s3, taking different measures according to different working conditions of the open cut tunnel under construction during undercrossing; s4, settlement control measures are taken for the ground surface at the stage that the shield penetrates through the open-cut tunnel under construction; and S5, safety construction is carried out after shield crossing. The construction method has the effect of improving the construction efficiency.
本申请涉及一种盾构区间共线近距离下穿在建明挖隧道施工方法，属于建筑施工的技术领域，其包括以下步骤：S1、盾构下穿在建明挖在建明挖隧道前条件核查通过验收，充分了解在建明挖隧道与区间隧道的位置关系及下穿段地质情况，根据设计要求制定可靠的施工方案；S2、盾构机正式穿越在建明挖在建明挖隧道前，需对盾构机进行一次系统而全面的检查和维保；S3、下穿时根据在建明挖在建明挖隧道所处的不同工况采取不同的措施；S4、对盾构下穿在建明挖在建明挖隧道阶段地表采取沉降控制措施；S5、盾构穿越后进行安全施工。本申请具有提高施工效率的效果。
