Construction method for pile foundation in karst area
The invention discloses a karst area pile foundation construction method. The karst area pile foundation construction method comprises the following steps that firstly, surveying and setting out are conducted; 2, a drilling machine is positioned and centered; thirdly, a drill bit and a steel sleeve are installed; 4, drilling construction is conducted; step 5, checking and accepting formed holes; sixthly, a reinforcement cage is manufactured; seventhly, a reinforcement cage is enclosed; eighthly, the reinforcement cage is hoisted and placed; ninthly, a guide pipe is installed; tenthly, concrete is poured; eleventhly, the steel sleeve is dismantled; and twelfthly, pile foundation and pile forming quality detection is conducted. According to the karst area pile foundation construction method, the engineering quality and safety are effectively guaranteed, the construction efficiency is improved, the concrete is prevented from exceeding the square, meanwhile, the construction cost is saved, and remarkable economic benefits are brought.
本发明公开了一种岩溶地区桩基施工方法，包括如下步骤：步骤一：测量放样；步骤二：钻机就位对中；步骤三：安装钻头及钢套管；步骤四：钻进施工；步骤五：成孔验收；步骤六：制作钢筋笼；步骤七：围挡钢筋笼；步骤八：吊放钢筋笼；步骤九：安装导管；步骤十：浇筑混凝土；步骤十一：钢套管拆除；步骤十二：桩基及成桩质量检测。本发明提供的一种岩溶地区桩基施工方法，有效保证了工程质量、安全，提高了施工效率，在避免出现混凝土超方的同时，节约了施工成本，带来了显著的经济效益。
