Construction method of building pile foundation
The invention relates to the technical field of pile foundation construction, in particular to a construction method of a building pile foundation. The method comprises the following steps of S1, drilling a pile hole; S2, sinking a steel reinforcement cage; S3, pouring concrete slurry till the concrete slurry is spilled from an opening of the pile hole; S4, striking off the concrete slurry; and S5, adopting a rigid object for sealing the opening of the pile hole, wherein the concrete slurry is prepared from, by mass, 100 parts of silicate cement, 180-200 parts of coarse aggregates, 220-250 parts of fine aggregates, 10-12 parts of a concrete expansive material, 5-8 parts of niobium pentoxide and 90-110 parts of water. The method has the effects that the pile body is stable in soil and therefore the stability of the pile foundation is high.
本发明涉及桩基施工的技术领域，具体涉及一种建筑桩基的施工方法，其包括以下步骤：S1.钻挖桩孔；S2.沉入钢筋笼；S3.浇注混凝土浆液至与桩孔口部溢出；S4.刮平混凝土浆液；S5.采用刚性物品封闭桩孔口部；混凝土浆液包括以下质量份数的组分：硅酸盐水泥100份；粗集料180‑200份；细集料220‑250份；混凝土膨胀剂10‑12份；五氧化二铌5‑8份；水90‑110份。本发明具有桩身在土壤中较为稳定，从而使得桩基的稳定性较高的效果。
