Cement stirring pile and construction technology thereof
The invention relates to the field of cement stirring piles, and particularly discloses a cement mixing pile and a construction technology thereof. The cement stirring pile construction technology comprises the following steps that (1), construction preparation is conducted; (2) a pile machine is in place; (3) pre-stirring and sinking are conducted; (4) cement paste is prepared, specifically, 380-450 parts by mass of undisturbed soil, 45-55 parts by mass of cement, 0.2-0.25 part by mass of calcium formate, 0.15-0.2 part by mass of anhydrous sodium sulfate and 0.1-0.15 part by mass of nano barium sulfate are added into a paste collecting barrel and uniformly stirred to obtain the cement paste, and sieving is conducted for later use; (5) guniting and stirring are conducted; (6) stirring and sinking are repeated; (7) guniting is conducted, and stirring and lifting are repeated; and (8) pile machine displacing is conducted. The cement stirring pile has higher early strength and better reinforcing effect.
本申请涉及水泥搅拌桩领域，具体公开了水泥搅拌桩及其施工工艺。水泥搅拌桩施工工艺，包括以下步骤：步骤1）施工准备；步骤2）桩机就位；步骤3）预搅下沉；步骤4）配制水泥浆：将原料380‑450质量份原状土、45‑55质量份水泥、0.2‑0.25质量份的甲酸钙、0.15‑0.2质量份的无水硫酸钠、0.1‑0.15质量份的纳米硫酸钡加入到集浆桶，搅拌均匀，得到水泥浆，过筛，备用；步骤5）喷浆搅拌；步骤6）重复搅拌下沉；步骤7）喷浆重复搅拌提升；步骤8）桩机移位。本申请的水泥搅拌桩具有更高的早期强度及更好的加固效果。
