Problems solved by technology

[0003] The usual aramid fiber reinforcement method for power transmission and transformation steel-concrete structures includes replacing relevant components on site. This method requires large-scale and long-term power outages, which seriously affects the normal production order; followed by high costs and direct economic losses. Larger, so this method is difficult to use in practice

Abstract

The invention provides an aramid fiber reinforcing method for a reinforced concrete structure support frame for power transmission and transformation and the like and a reinforced structure support frame, wherein the reinforcing method comprises the following steps of: 1, repairing a crack of a power transmission and transformation structure support frame; 2, repairing the damage part of the power transmission and transformation structure support frame; 3, using aramid fiber or carbon fiber for reinforcing and enhancing the power transmission and transformation structure support frame; and 4, using fabrics for reinforcing and protecting the power transmission and transformation structure support frame. The fabrics and an infusion protection rubber layer are arranged on the outer surface of the reinforced structure support frame, and the infusion protection rubber layer is attached onto the surfaces of the fabrics. The reinforcing method has the technical scheme that on the site, the power transmission and transformation structure support frame is directly reinforced, enhanced and protected, so that the safety, the use function and the durability of the power transmission and transformation structure support frame are recovered. Technologies such as aramid fiber / carbon fiber reinforcement, macromolecule crack grouting, new and old material combination, high-strength micro expansion material / polymer mortar repairing and macromolecule fabric membrane protection are used, so that the on-line restoration, reinforcement or enhancement on high-voltage electric network structure support frames in various damage states is realized.

Description

technical field [0001] The invention relates to the reinforcement technology of existing buildings / structures, in particular to an aramid fiber reinforcement method for power transmission and transformation steel-concrete structure brackets and the reinforced brackets. Background technique [0002] my country has a vast territory, and the power load in many areas is mainly industrial load. The increase in the running time of the power system, the long-term effects of harmful substances such as acids, alkalis, and salts discharged from steel and chemical companies in the region, and the damage of freezing and thawing, carbonization, aging, temperature alternation, and salt corrosion have caused a large number of power transmission systems to The substation steel-concrete structure support is aging, corroded, cracked, peeling, bulged, and the steel bars are corroded. The damage of the structural support is gradually accelerating, which seriously threatens the safe and stable ...
