Problems solved by technology

[0003] When the transmission line passes through corrosive geological conditions, with the increase of line operation time, part of the external concrete of the foundation will be damaged due to corrosion, resulting in insufficient reinforced concrete protective layer on the outside of the foundation, and even directly leading to the exposure of steel bars, thereby affecting the transmission line. Safe operation brings operational safety hazards
[0004] At present, there is no good treatment method for this kind of problem. Usually, it can only be dealt with by external brushing of mortar and anti-corrosion coating. corroded and destroyed again

Embodiment Construction

[0035] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] The transmission line tower foundation that the embodiment of the present invention provides, such as figure 1 As shown, the foundation is in the shape of an inverted T, and there is a stepped protrusion at the intersection of the column 1 and the bottom plate 2, including the column 1, the bottom plate 2, the anchor bolts 3, the reinforcement 4, and the concrete 5. The column 1, the bottom plate 2 and the step-shaped protrusion are poured into one body through concrete 5, and the vertical and horizontal intersecting reinforcement 4 is laid in the column 1 and the bottom plate 2, and the column 1 is inserted vertically through it and protrudes from the top surface of the column 1. foot bolt 3.

Abstract

The invention provides an anti-corrosion reinforcement method for a transmission line pole and tower foundation. The method is used for the repair and reinforcement of a transmission line pole and tower foundation damaged by corrosion. The improvement lies in that the foundation is in an inverted T shape, and a vertical column and a bottom plate are arranged at the intersection of the foundation. There are stepped protrusions; the methods of repair and reinforcement are cleaning, reinforcement, grouting and painting to ensure the normal operation of the damaged foundation and improve the anti-corrosion ability of the foundation. Compared with the prior art, the anti-corrosion reinforcement method for the transmission line pole and tower foundation provided by the present invention repairs and reinforces the foundation damaged by corrosion through simple and convenient construction, improves the strength of the foundation, prolongs the service life of the foundation, and saves money. Basic maintenance costs.

Description

technical field [0001] The invention relates to a foundation anticorrosion reinforcement method, in particular to a transmission line tower foundation anticorrosion reinforcement method. Background technique [0002] With the accelerating pace of electric power development, the power grid has also developed rapidly, the operating voltage level of the power grid system has been continuously improved, and the network scale has also been continuously expanded. Power grid construction has become the main content of electric power construction, and by 2020, a powerful smart grid will be built in an all-round way. [0003] When the transmission line passes through corrosive geological conditions, with the increase of line operation time, part of the external concrete of the foundation will be damaged due to corrosion, resulting in insufficient reinforced concrete protective layer on the outside of the foundation, and even directly leading to the exposure of steel bars, thereby aff...
