Abstract

The invention relates to the field of transmission equipment, in particular to a concrete pole. Concrete is uniformly distributed on a reinforcing steel bar mesh, so that the pole is formed. The concrete comprises raw materials in parts by mass as follows: 480-550 parts of low-alkaline Portland cement or ordinary Portland cement with an average grain diameter of 30-60 mu m, 120-140 parts of silica fume with an average grain diameter of 0.18 mu m and the SiO2 content of no less than 85%, 80-110 parts of I-level pulverized fuel ash with an average grain diameter of 10-20 mu m, 110-140 parts of slag powder with the level higher than S95 and an average grain diameter of 10-30 mu m, 510-550 parts of quartz sand with a grain diameter of 0.16-1.63 mm, 860-920 parts of cobbles with a grain diameter of 5-14 mm, 14-18 parts of a compound high-efficiency slushing agent with a water-reducing rate higher than 30%, 7-12 parts of a corrosion inhibitor, 120-140 parts of water, 70-110 parts of a copper plating steel fiber with a diameter of 0.18-0.25 mm and a length of 10-15 mm and 0.8-1.5 parts of a polypropylene fiber. Prestressed wires with a diameter of 4.8-10.7 mm and taken as main bars and high-strength hard-drawn wires with a diameter of 3.0-5.0 mm and taken as circular structural bars are woven, so that the reinforcing steel bar mesh is formed.

Description

technical field [0001] The invention relates to the field of power transmission equipment, in particular to a concrete pole. Background technique [0002] RPC (Reactive Powder Concrete) is a new type of concrete material with ultra-high strength, high toughness, high durability and stable volume developed by Western countries such as France in the early 1990s. This material is now mainly used and promoted abroad. It is 200MPa level, the performance compression index can reach 130~200MPA, the flexural strength can reach 16~50MPA, the elastic modulus is above 45GPa, the impermeability is generally above P30, the carbonization detection is 0 in 28 days, and the electric flux is less than 40 Cullen. In China, RPC materials have been continuously researched and developed. They are mainly used in railway engineering and bridge prefabrication, and their application in the concrete pole engineering industry for power transmission is still blank. At present, concrete poles for powe...
