Manufacturing and mounting method of anti-freezing foundation pile for photovoltaic support in frozen earth area
The invention belongs to the technical field of building construction, and particularly relates to a manufacturing and mounting method of an anti-freezing foundation pile for a photovoltaic support in a frozen earth region, which comprises the following steps: 1, manufacturing a precast pile body, winding a spiral hoop around a longitudinal bar to form a stirrup, and welding the stirrup and a steel embedded part together to form the precast pile body; the outer layer of the precast pile body is pre-wrapped with a heat preservation layer, the heat preservation layer is taken down after pre-wrapping, and the inner surface of the heat preservation layer is coated with inner-layer industrial vaseline; 2, after the prefabricated pile body is transported to a construction site and the installation position is determined, a guide hole is formed in the frozen soil layer of the installation area, and the hole diameter of the guide hole is 250 mm larger than the outer diameter of the prefabricated pile body; and 3, a layer of polypropylene waterproof base cloth is laid in the guide hole, a pile casing is placed in the guide hole, the outer portion of the polystyrene foam board heat preservation layer is coated with industrial vaseline, then the polystyrene foam board heat preservation layer is placed in the pile casing, fine aggregate concrete is injected between the polystyrene foam board heat preservation layer and the pile casing, and after the fine aggregate concrete is completely solidified, installation of the foundation column is completed.
本发明属于建筑施工技术领域，具体涉及一种用于冻土地区光伏支架的防冻基础桩的制作及其安装方法，1、制作预制桩体，在纵筋的四周缠绕螺旋箍制成箍筋，将该箍筋与钢制预埋件焊接在一起制成预制桩体，预制桩体外层用保温层进行预包裹，预包裹后取下保温层，在保温层的内表面涂上内层工业凡士林；2、将预制桩体运至施工现场并确定安装位置后，在安装区域的冻土层下开引孔，引孔的孔径比预制桩体的外径大250mm；3、在引孔内铺设一层聚丙烯防水基布，将护筒放入引孔内，再将聚苯乙烯泡沫板保温层的外部涂上工业凡士林后放入护筒内，将细石混凝土注入聚苯乙烯泡沫板保温层和护筒之间，等待细石混凝土完全凝固后基础柱安装完成。
