Treatment method for underground pipeline or karst cave
The invention discloses a treatment method for an underground pipeline or a karst cave, and relates to the technical field of concrete pouring. The method comprises the following steps that materials are prepared, specifically, an outer pile casing, an inner pile casing, a reinforcement cage, a concrete body and clay are prepared; the outer pile casing is installed, specifically, the outer pile casing is installed till the outer pile casing is installed to a preset position; clay backfilling is conducted, specifically, clay is backfilled into the outer pile casing, and a clay layer is formed; hole digging is conducted, specifically, mechanical equipment is used for digging holes in the clay layer, and pile foundation construction holes are formed; pile foundation forming preparation is carried out; and a pile foundation is formed. According to the method, through cooperation of all the steps, the phenomenon of hole collapse caused by the influence of the underground pipeline or karst cave when the pile foundation construction holes are dug during underwater construction can be effectively avoided, the situation that piles cannot be formed due to the ash leakage phenomenon during concrete pouring can be effectively avoided, the construction amount is effectively reduced, and the construction efficiency is improved.
本发明公开了一种针对地下管线或者溶洞处理方法，涉及混凝土灌注技术领域。本发明包括有以下步骤：材料准备，对外护筒、内护筒、钢筋笼、混凝土本体和黏土进行准备；外护筒安装，对外护筒进行安装，直至外护筒安装至预定位置；黏土回填，将黏土回填进入外护筒的内部，形成黏土层；挖孔，使用机械设备对黏土层进行挖孔，形成桩基础施工孔；桩基础成型准备；桩基础成型。本发明通过各个步骤的配合能够有效的避免在水下进行施工时，因受到地下管线或者溶洞的影响，对桩基础施工孔进行挖孔时出现塌孔现象，且能够有效的避免在浇筑混凝土时因出现跑灰现象而无法成桩，并有效的减少施工量，提升施工效率。
