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.

[0037] The anti-corrosion reinforcement method of the transmission line tower foundation provided in this embodiment, s...

Abstract

The invention provides an anticorrosion reinforcing method of a transmission line tower foundation. The anticorrosion reinforcing method is used for repairing and reinforcing the transmission line tower foundation which is corroded and destroyed and is characterized in that the foundation is in a reversed T shape, and step-shaped projections are arranged at the joint of a stand column and a base plate of the foundation; the repairing and reinforcing method includes cleaning, reinforcing, grouting and painting, normal work of the damaged foundation is guaranteed, and anticorrosion capacity of the foundation is improved. Compared with anticorrosion reinforcing methods in the prior art, the anticorrosion reinforcing method of the transmission line tower foundation has the advantages that through simple and convenient construction, the foundation which is corroded and destroyed is repaired and reinforced, strength of the foundation is improved, service life of the foundation is prolonged, and foundation maintenance expenses are saved.

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...
