Construction method of building pile foundation
The invention relates to the technical field of building construction, in particular to a construction method of a building pile foundation. The construction method includes the following steps of (1)alignment measurement; (2) excavation of an installing hole; (3) installation of a protective sleeve; (4) drilling; (5) hole cleaning; (6) hoisting and placement of a steel reinforcement cage; and (7) pouring of cement mortar, wherein the cement mortar comprises the following components including, by mass, 50-65 parts of cement, 15-20 parts of water, 60-80 parts of coarse aggregate, 30-45 parts of fine aggregate, 1-3 parts of borax, 0.5-1 part of zirconium oxychloride, and 0.1-0.2 part of ammonium molybdate. By means of the construction method of the building pile foundation, the effect of reducing influence, on the compressive strength of a pile foundation, of moisture in a pile foundation hole is achieved.
本发明涉及建筑施工的技术领域，涉及一种建筑桩基的施工方法，其包括以下步骤：步骤（1），放线测量；步骤（2），开挖安装孔；步骤（3），安装防护套；步骤（4），钻孔；步骤（5），清孔；步骤（6），吊放钢筋笼；步骤（7），灌注水泥砂浆；其中，水泥砂浆包括以下质量份数的组分：水泥50‑65份；水15‑20份；粗集料60‑80份；细集料30‑45份；硼砂1‑3份；氧氯化锆0.5‑1份；钼酸铵0.1‑0.2份。本发明具有减少桩基孔内的水分对桩基的抗压强度造成影响的效果。
