Reinforcing method in bored pile construction based on overwater operation platform
The invention discloses a reinforcement method in bored pile construction based on an overwater operation platform, which comprises the following steps: pile casing burying: pile casing burying is carried out along a reserved pile foundation position of the overwater operation platform, the pile casing is fixedly connected with the overwater operation platform, and the first section of pile casing extends to a position above the operation platform; the soil body on the periphery of the pile casing is subjected to grouting reinforcement, so that the soil body on the periphery of the pile casing is solidified, and an impervious layer is formed; and drilling and hole forming are conducted, specifically, drilling and hole forming operation in the pile casing are conducted along the overwater operation platform, sludge generated during drilling is separated and then mixed with pre-stored slurry, and the sludge flows back into the pile casing in the state of high-quality slurry. Through the steps of pile casing burying, pile casing reinforcing, slurry recycling and the like, underwater large-diameter deep and long pile foundation construction under the complex geological conditions such as a sludge stratum is achieved.
本发明公开了基于水上作业平台的钻孔桩施工中的加固方法，包括以下步骤，护筒埋设：沿水上作业平台的预留桩基位置，进行护筒埋设，所述护筒与水上作业平台固定连接，且第一节护筒延伸至所述作业平台之上；护筒加固：对所述护筒外周的土体进行注浆加固，使得护筒外周的土体固结，形成不透水层；钻进成孔：沿水上作业平台，分别进行护筒内的钻进和成孔操作，将钻进中产生的泥渣进行分离后，与预存泥浆混合，以优质泥浆的状态，回流至护筒内。本发明通过护筒埋设、护筒加固以及泥浆的循环利用等步骤，实现了对于淤泥地层等复杂地质条件的水下大直径深长桩基施工。
