Embodiment 1
[0025] Such as figure 1 , 2 As shown, a pole anti-seismic mechanism includes a base 1, the base 1 is a prism, the upper end of the base 1 is provided with a positioning groove 2, and a vertical orientation is set between the bottom of the pole 3 and the positioning groove 2 The spiral pressure spring 4 locks the bottom of the electric pole 3 and the base 1, and a disc hoop 5 is arranged around the pole 3, and the disc hoop 5 is provided with equidistant circular holes 6, and the base 1 and the disc The hoop 5 is formed by pouring concrete.
[0026] The concrete is made of the following raw materials in parts by weight: 70 parts of P.O42.5 portland cement, 10 parts of steel fiber, 10 parts of polyacryl alcohol fiber, 20 parts of fly ash, 50 parts of mineral powder, medium 50 parts of sand, 25 parts of water and 10 parts of polycarboxylate superplasticizer. Add the above-mentioned various raw materials into the blender in turn, and mix evenly to obtain the product.
[0027] ...
Embodiment 2
[0032] The anti-seismic mechanism of the electric pole in this embodiment is as described in Embodiment 1, and the same parts will not be repeated. Some differences are: the positioning groove 2 is filled with asphalt, and the lower end of the helical pressure spring 4 is embedded in the in asphalt.
[0033] The concrete is made of the following raw materials in parts by weight: 75 parts of P.O42.5 portland cement, 5 parts of steel fiber, 13 parts of polypropylene alcohol fiber, 30 parts of fly ash, 60 parts of mineral powder, medium 50 parts of sand, 26 parts of water and 15 parts of polycarboxylate superplasticizer. Add the above-mentioned various raw materials into the blender in turn, and mix evenly to obtain the product.
[0034] The steel fiber is hook-shaped, with a diameter of 0.2-0.5mm, a length of 20-30mm, and a tensile strength of ≥1000N / mm 2 .
[0035] The diameter of the polypropylene alcohol fiber is 0.6-0.8mm, the length is 40-60mm, and the tensile strength i...
Embodiment 3
[0039] The anti-seismic mechanism of the electric pole in this embodiment is as described in Embodiment 2, and the same parts will not be repeated. Some differences are: the base is a circular platform, and the cross-sectional area of the helical pressure spring 4 is the same as that of the electric pole 3 .
[0040] The concrete is made of the following raw materials in parts by weight: 80 parts of P.O52.5 portland cement, 11 parts of steel fiber, 15 parts of polyacryl alcohol fiber, 30 parts of fly ash, 62 parts of mineral powder, medium 65 parts of sand, 30 parts of water and 20 parts of polycarboxylate superplasticizer. Add the above-mentioned various raw materials into the blender in turn, and mix evenly to obtain the product.
[0041] The steel fiber is hook-shaped, with a diameter of 0.2-0.5mm, a length of 20-30mm, and a tensile strength of ≥1000N / mm 2 .
[0042] The diameter of the polypropylene alcohol fiber is 0.6-0.8mm, the length is 40-60mm, and the tensile st...
