Treatment method of karst tunnel
The invention discloses a treatment method of a karst tunnel. The treatment method comprises the following steps that a construction area is arranged on the bottom face of the karst tunnel; a bored pile is mounted in the construction area; a pore structure is formed in the top surface of the bored pile; a foundation pit is excavated in the construction area; a pile head, protruding out of the foundation pit, of the bored pile is chiseled away, so that the top face of the bored pile is flush with the bottom face of the foundation pit; and concrete is poured into the foundation pit so that the concrete can permeate into the pore structure of the top face of the bored pile, and after the concrete is solidified, a foundation is formed. It can be understood that the stable foundation is formed,and the problem that the bottom wall of the construction tunnel collapses is avoided.
本发明公开一种岩溶隧道的处理方法，包括以下步骤：在岩溶隧道的底面设置施工区域；安装钻孔桩于所述施工区域；其中，所述钻孔桩的顶面开设有孔隙结构；在所述施工区域开挖基坑；凿除所述钻孔桩凸出所述基坑的桩头，以使所述钻孔桩的顶面与所述基坑的底面相平；向所述基坑中浇筑混凝土，以使所述混凝土渗透进入所述钻孔桩的顶面的孔隙结构之中，待所述混凝土固化后，形成地基。可以理解的，本发明形成了稳定的地基，避免了施工隧道底壁坍塌的问题。
