Tunnel bottom combined type reinforcement treatment method for crossing large-scale fully-filled karst cave
The invention relates to the field of tunnel engineering, in particular to a tunnel bottom combined type reinforcement treatment method for crossing a large-scale fully-filled karst cave. A to-be-reinforced region is divided into at least two regions in the longitudinal direction of a tunnel, the regions comprise a first reinforcement region and a second reinforcement region. The following steps are sequentially carried out of S1, applying a lower reinforcement structure in the range of a lower beaded small karst cave to the first reinforcement region, and simultaneously applying an upper reinforcement structure in the range of an upper fully-filled karst cave to a second reinforcement region; and S2, applying the upper reinforcement structure in the range of the upper fully-filled karst cave to the first reinforcement region, and simultaneously applying the lower reinforcement structure in the range of the lower beaded small karst cave to the second reinforcement region. According tothe tunnel bottom combined type reinforcement treatment method for crossing the large-scale fully-filled karst cave, the working surface is increased, and the tunnel bottom reinforcement time is shortened.
本发明涉及隧道工程领域，具体涉及一种穿越大型全充填溶洞的隧底复合式加固处理方法，对待加固处理的区域进行分区，在隧道的纵向方向上，分为至少两个区域，包括第一加固区和第二加固区；依次进行以下步骤：S1.对第一加固区，施作下部串珠状小溶洞范围内的下部加固结构，同时对第二加固区，施作上部全充填溶洞范围内的上部加固结构；S2.对第一加固区，施作上部全充填溶洞范围内的上部加固结构，同时对第二加固区，施作下部串珠状小溶洞范围内的下部加固结构。本发明的一种穿越大型全充填溶洞的隧底复合式加固处理方法，能够增加作业面，缩短隧底加固时间。
