Concrete pole with high crack resistance and preparation method thereof
The invention discloses a high-crack-resistance concrete pole and a preparation method thereof, and the high-crack-resistance concrete pole comprises a pouring mold which is used for limiting the shape and appearance of the concrete pole; the electric pole comprises an electric pole body, a main steel bar frame is arranged in the electric pole body, the main steel bar frame is formed by sequentially and annularly arranging a plurality of steel bars, and a plurality of stirrups which are vertically arranged are arranged outside the main steel bar frame. The heat capacity of the electric pole is increased by adding sand into the hollow spiral pipe at the low temperature, loss of heat in the electric pole is relieved, the temperature of concrete can be kept, stress caused by temperature change can be relieved, and therefore the risk that the concrete electric pole cracks under temperature fluctuation is reduced; by means of evaporation and conduction characteristics of water, the overall temperature of the electric pole is reduced, material performance degradation caused by high temperature and thermal expansion and cold contraction of concrete and reinforcing steel bars are prevented, the service life of the electric pole is prolonged, the electric pole is prevented from being cracked and damaged, and the crack resistance of the electric pole is effectively improved.
本发明公开一种抗裂性高的混凝土电杆及其制备方法，包括：浇筑模具，浇筑模具用于限制混凝土电杆的形状和外观；电杆主体，电杆主体的内部设置有主钢筋架，主钢筋架由多个钢筋依次呈环状排列而成，主钢筋架的外部设置有多个垂直排列的箍筋。本发明低温时通过向中空螺旋管中添加沙子增加电杆的热容，减缓电杆内部热量的散失，有助于保持混凝土的温度，帮助缓解因温度变化引起的应力，从而降低混凝土电杆在温度波动下裂缝的风险，高温时通过向中空螺旋管中加入水，利用水的蒸发和传导特性，降低电杆的整体温度，防止因高温导致的材料性能劣化、混凝土和钢筋的热胀冷缩，延长电杆使用寿命，防止电杆干裂和损伤，有效提高电杆的抗裂性。
