Embodiment 1
[0047] Example 1 Environment-friendly low-stress concrete pole and its preparation
[0048] The environmentally friendly low-stress concrete pole is formed by wrapping steel rod skeleton with concrete, wherein the steel rod skeleton includes main reinforcement and auxiliary reinforcement, the main reinforcement is axially arranged inside the pole, and the auxiliary reinforcement is spirally welded to the periphery of the main reinforcement;
[0049] Wherein, the main reinforcement is a prestressed steel bar, which is a medium-carbon alloy hot-rolled steel bar 30nmsi, which is formed through electrothermal quenching and tempering heat treatment, and the auxiliary reinforcement adopts cold-drawn low-carbon steel wire. 60mm, the helical pitch within 1000mm from the end of the spiral rib is 60mm, and the helical pitch of the remaining length of the spiral rib is 100mm;
[0050] Said concrete consists of 100 parts of cement, 120 parts of sand, 260 parts of gravel, 4.0 parts of nano...
