Problems solved by technology

However, the disclosed method and reinforcing member in CN1438101A have the following disadvantages: (1) because the reinforced utility poles may have different inner diameters, different sizes of reinforcing member deploying devices are required, that is, one deploying device cannot be applied to different diameters of utility poles. inner diameter of the pole; (2) inserting and placing the reinforcement inside the pole is difficult and time consuming; and (3) the reinforcement inside the pole cannot be in close contact with the interior of the pole, and therefore cannot achieve optimal Enhanced effect of

Embodiment Construction

[0049] In the present invention, unless otherwise specified, "telephone pole" generally means an existing hollow concrete utility pole in use. Usually, the utility pole has different inner diameters up and down, for example, the inner diameter of the upper part is smaller than that of the lower part. The invention is also applicable to the reinforcement of utility poles with the same upper and lower inner diameters.

[0050] In the present invention, unless otherwise specified, "open" and / or "closed" are relative concepts relative to the central support rod. For example, "closed" means that the connecting rod is parallel to the central support rod or the smallest angle it is allowed to achieve relative to the central support rod in the stiffener. "Open" means that the angle (acute angle) between the connecting rod and the central support rod is greater than 0 degrees to equal to 90 degrees, such as 10 degrees, 20 degrees, 30 degrees, 45 degrees, 60 degrees, etc., depending on...

Abstract

The invention provides a strengthening device used for strengthening a traditional telegraph pole, comprising a central support pole, one or a plurality of strengthening parts, one or a plurality of connecting poles and one or a plurality of control devices, wherein each strengthening part can express an opening and / or closing state relative to the central support pole; one end of each connecting pole can be rotatably connected to the central support pole, and the other end of each connecting pole can be rotatably connected to each strengthening part; and each control device is used for controlling opening or closing of each strengthening part. The invention also provides a method for strengthening the traditional telegraph pole.

Description

technical field [0001] The invention relates to a method for introducing a reinforcing device into an installed concrete utility pole to realize reinforcement and reinforcement of the utility pole. Background technique [0002] Installed existing concrete utility poles, the bottom of the concrete utility pole is buried in the ground, and its upper part is exposed on the ground. [0003] In order to strengthen the existing concrete utility poles to solve their aging and other situations, conventional strengthening methods such as enclosing reinforcement devices on the outer surface of concrete utility poles, such as aramid fiber epoxy resin composite materials or increasing the concrete cross-sectional area, can be used. [0004] Usually the range of reinforced concrete utility poles is the bottom of the ground, including the boundary part relative to the ground to its upper part. [0005] That is, when the concrete utility pole is reinforced using a conventional strengtheni...
