1980s, China's development of prestressed concrete pole ring centrifugation. Its manufacturing process is mainly the steel skeleton longitudinal tension in the steel and the concrete under the centrifugal force out excess moisture, thus greatly improve the density and strength of the concrete. In order to make concrete can quickly reach more than 70% of the design strength can be steam curing, to shorten the stripping cycle. The use of prestressed concrete pole than saving steel with reinforced concrete poles, but also improve the crack resistance and service life. In general, the line is longer, thicker wire diameter cement poles, the line tension is large, according to the thickness of the cement poles parameter line segment of length, diameter, which is based on the size of the line to determine the tension of the cable thickness, pull the disk size, the thickness of the pull rod. Cross-section of the cable to pull the wire with the corresponding cross-section of its strength design safety factor of not less than 2, the minimum size of not less than 35mm2. Rod diameter of not less than 16mm cement poles manufacturing, pull the disc is not less than 40cm × 60cm. Burial depth Drawers should be based on soil conditions and determine the pole overturning moment, its pullout stability safety factor of not less than the following data: linear rod 1.5, 1.8 Tension rods, corner bar, rod terminal 2. 0, depth generally not shallower than 2m. Wholesale required cement poles, the bottom portion of the exposed length of the floor should be 0.3 ~ 0.5m. Rod slightly shorter, pull the disc can be shallow depth of some, but not shallow burial depth in the line of poles.
