Shallow-buried tunnel over-arch open-construction under-arch undercutting construction method
The invention discloses a shallow-buried tunnel over-arch open-cut under-arch undercutting construction method, and relates to the technical field of tunnel construction. The method comprises the following steps that S1, a gutter is leveled, and a side slope is excavated; S2, an arch part is excavated through an open cut method; S3, an arch support is constructed; S4, a backfill surface on the arch is carried out; S5, three steps and a temporary inverted arch are excavated; S6, secondary lining is carried out; and S7, a waterproof layer is laid. According to the shallow-buried tunnel over-arch open-cut under-arch undercutting construction method, in shallow-buried under-crossing tunnel construction, ground surface settlement is effectively controlled, ground buildings are protected, the ground buildings are not affected by tunnel construction, the result of removing the ground buildings is avoided, the construction time is greatly saved, therefore the cost is saved, a tunnel secondary lining structure is reasonable in design, the construction method is simple, and the construction quality is easy to control, so that the construction cost can be greatly reduced, the construction period is shortened, the construction safety can be ensured, and good social benefits are achieved.
本发明公开了一种浅埋隧道拱上明作拱下暗挖施工方法，涉及隧道施工技术领域。包括以下步骤：S1、平整天沟和开挖边坡；S2、明挖法开挖拱部；S3、施作拱部支护；S4、拱上回填面；S5、三台阶+临时仰拱开挖；S6、二次衬砌；S7、铺设防水层。该浅埋隧道拱上明作拱下暗挖施工方法，本发明在浅埋下穿隧道施工中，有效的控制了地表沉降，保护了地面建筑物，使地面建筑物不因隧道施工而受到影响，避免了拆除地面建筑物的结果，大大节约施工时间，从而节约了成本，隧道二次衬砌结构设计合理且施工方法简单、施工质量易于控制，从而能大幅度降低施工成本，节约施工工期，并能确保施工安全，具有良好的社会效益。
