Construction method of solidified soil pile
The invention provides a construction method of a solidified soil pile. The construction method comprises the following steps (1) pre-mixing solidified soil; adding water into an air hardening inorganic cementing material for dilution and blending to form initial material slurry, blending the initial material slurry with a powdery curing agent to form curing agent slurry, and mixing the curing agent slurry with soil to form on-site blended solidified soil; (2) downward drilling to form a hole; firstly drilling downwards to a designed depth, and arranging a soil sampling device on a drill rod; (3) lifting a bit, pressing and filling solidified soil; and pressing and pouring the solidified soil in the step (1) into a pile hole to form the solidified soil pile. According to the solidified soil pile constructed through the method, the air hardening inorganic cementing material is added, the solidification time of solidified soil is adjusted, and the acid-base property of the solidified soil is adjusted; and the slag is doped to reduce the cement consumption, the cost is greatly saved, the pile body strength is high, the bearing capacity is high, the construction process is simple, and the construction efficiency is high.
本发明提供一种固化土桩的施工方法，包括以下步骤：1)预拌固化土；将气硬性无机胶凝材料加水稀释拌和成初始物料浆液，初始物料浆液与粉状固化剂拌和形成固化剂浆液，固化剂浆液与泥土混合形成现场拌和的固化土；2)下钻成孔；先下钻至设计深度，钻杆上设置有取土装置；3)提钻压灌固化土；向桩孔内压灌步骤1)中的固化土，形成固化土桩。本方法施工的固化土桩，添加有气硬性无机胶凝材料，调节固化土的凝固时间，调节固化土的酸碱性；掺入矿渣减少水泥用量，大大节省成本，桩身强度高，承载力强，施工工序简单，施工效率高。
