Manufacturing technology for autoclaving-free pole

Abstract

The invention provides a manufacturing technology for an autoclaving-free pole. The specific machining technology comprises the following steps that one, prestressed steel bars and screw-thread steelare machined; two, a steel bar framework is manufactured; three, a concrete mixture is manufactured; four, mold closing and formation of the autoclaving-free pole are conducted; five, natural curing is conducted; six, mold removing is conducted; and seven, finished product inspection is conducted. The manufacturing technology for the autoclaving-free pole has the beneficial effects that by means of improvement of raw material quality, optimization of mixing proportion and adoption of an efficient water reducing agent, a large amount of energy consumption is saved on the premise that physical and mechanical properties, durability and production time of the pole are guaranteed; a cost ranging from 30 rmb to 60 rmb can be saved by each pole; production cost is reduced greatly; the history ofhigh energy consumption of the pole is changed completely; a novel breakthrough of the pole is achieved; the concrete of the autoclaving-free pole is high in durability such as chloride corrosion resistance property, freezing resistance and the like and high in latter strength; a strength loss of 17% of steam curing is avoided; the autoclaving-free pole is artistic in appearance; a non-pulp-pouring technology is adopted; meanwhile, numerous troubles of the remaining pulp are avoided; and the manufacturing technology is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of electric pole production technology, in particular to the production technology of a steam-free electric pole. Background technique [0002] The production process of poles includes steel frame forming, concrete mixing, mold clamping, centrifugal forming, steam curing, mold removal, finished product inspection and other production processes. In the whole process of pole production, in order to improve the early strength of poles, shorten the demoulding time and improve work efficiency, steam curing is required, and water curing is carried out after demoulding. The steam curing process consumes a lot of energy, which not only increases the production of poles It also affects the concrete performance of the pole. It can be seen that how to effectively reduce energy consumption and reduce carbon emissions in the production process of poles on the basis of ensuring and improving pole performance and template...
