Manufacturing method for improving prestress of concrete pole
The invention provides a manufacturing method for improving the prestress of a concrete electric pole, and relates to the technical field of electric pole production processes. The manufacturing method for improving the prestress of the concrete pole comprises the following steps that S1, a mold A of a cement outer cylinder is prefabricated according to the outer diameter of the cement outer cylinder being 50-60 cm, the thickness of the cement outer cylinder being 50-70 mm and the height of the cement outer cylinder being 5-8 m; s2, a cement outer cylinder is manufactured according to the mold A in the step S1, and a mold B of an inner triangular steel frame is correspondingly manufactured. Sleeving the inner triangular steel frame finished product into a mold A, preparing a cement outer cylinder and obtaining a semi-finished product blank liquid, adding silica fume and silica fume into a stirrer, and mixing and stirring with the mixed adhesive cement A for 2-3 hours at the temperature of 100-110 DEG C and the rotating speed of 15-20 revolutions per minute to obtain a semi-finished product blank liquid; and the water consumption of the concrete is reduced under the combined action of the silica fume and the polycarboxylic acid water reducer, and the setting and hardening of the cement concrete are accelerated.
本发明提供一种提高水泥电杆应预力的制作方法，涉及电杆生产工艺技术领域。该提高水泥电杆应预力的制作方法，包括以下步骤：S1、首先根据水泥外筒的外径50～60厘米、厚度50～70毫米、高度5～8米尺寸预制出水泥外筒的模具A；S2、根据S1步骤所属的模具A制作出水泥外筒并对应制作出内三角钢架的模具B。通过再将内三角钢架成品套入至模具A内，制备水泥外筒并得到半成品坯液，微硅粉以及微硅粉加入至搅拌机内，在100～110摄氏度以及15～20转每分钟转速下与混合胶浆A混合搅拌2～3小时，得到半成品坯液，采用微硅粉与聚羧酸系减水剂共同作用降低混凝土的用水量，加速水泥混凝土的凝结硬化。
