Underwater cast-in-situ bored pile reverse circulation efficient hole-forming construction device and method
The invention relates to an underwater cast-in-situ bored pile reverse circulation efficient hole-forming construction device and method, and relates to the field of cast-in-situ bored pile construction. The underwater cast-in-situ bored pile reverse circulation efficient hole-forming construction method comprises the following steps that construction is prepared; a mud pit is manufactured; a slurry pipe and a slurry groove are designed; holes are drilled; slurry reverse circulation work is carried out; and slurry firstly enters a settling pond before entering a slurry pit, and the slurry in the settling pond overflows into the slurry pit. According to the underwater cast-in-situ bored pile reverse circulation efficient hole-forming construction device and method, the slurry pit is arranged on a drilling platform in situ, so that the arrangement of a complex slurry long-distance pipeline is avoided, the construction difficulty is reduced, and the construction efficiency is improved; and a gate is adopted to control slurry feeding and stopping of the slurry pit, meanwhile, a slurry differential reverse circulation system is utilized to enable a water head in a steel casing to get rid of control over the slurry surface of the slurry pit, the hole collapse risk is reduced, and the hole forming efficiency is improved.
本申请涉及一种水中钻孔灌注桩反循环高效成孔施工装置及其方法，涉及灌注桩施工的领域，水中钻孔灌注桩反循环高效成孔施工方法包括如下步骤，施工准备；泥浆池制作；泥浆管以及泥浆槽设计；钻孔；泥浆反循环工作；泥浆进入到泥浆池前首先进入到沉淀池内，沉淀池中泥浆溢流至泥浆池内。本申请在钻孔平台上原位布设泥浆池，避免了复杂泥浆长输管道的布设，降低了施工难度，提高了施工效率的效果，采用闸门控制泥浆池进浆、停浆，同时利用泥浆差位反循环系统使得钢护筒内水头摆脱了泥浆池浆面的控制，降低了塌孔风险，提高了成孔效率。
