Telegraph pole and its mounting and fixing method

Abstract

The invention discloses a telegraph pole and an installing and fixing method thereof. The lower end of the telegraph pole is provided with through holes which cross through the telegraph pole body; the installing and fixing method comprises the following steps: a pre-buried pit is dug at the installing position of the telegraph pole, a steel bar is penetrated into the through holes at the lower end of the telegraph pole, the two ends of the steel bar are arranged outside the telegraph pole which is upright in the pre-buried pit, and a pouring frame with the shape being adapted to that of the pre-buried pit is constructed outside the two ends of the steel bar; and pouring is carried out in the pouring frame by using concrete, thus forming a base seat which is integrated with the telegraph pole. At least two pairs of through holes at the lower end of the telegraph pole are distributed uniformly and alternately; the cross section of the pre-buried pit is a regular quadrangle; the pouring frame is in the shape of a regular quadrangle frustum with small top and big bottom, and the pouring frame consists of hollow-out net boards. As the cast-in-situ base seat which forms into one firm body with the telegraph pole is added, and the surface is unsmooth, the force bearing area of the telegraph pole is increased, the gravity center is reduced, the anti-inclination and anti-toppling capacity of the telegraph pole is increased, and the telegraph pole is safe and reliable.

Description

technical field [0001] The invention relates to a power facility product and its installation method, in particular to an electric pole and its installation and fixing method. Background technique [0002] At present, the utility poles for erecting electric wires, no matter cement utility poles or utility poles made of other materials, are mostly in the shape of a truncated cone from top to bottom, and this utility pole is in the form of a truncated cone from top to bottom. Usually the installation method on the ground is to dig a foundation pit at the installation location, and after the electric pole is erected in the pit, it is fixed by backfilling with flakes and soil. The result is poor stability of the utility pole. Under the condition of external force, such as the pulling force of the wire, or the strong wind, no matter the external force or the wind comes from any direction, the utility pole is prone to inclination, and even causes the utility pole to break and fall...

AI Technical Summary

Problems solved by technology

Its shortcoming is that only the hollow part of the utility pole has been strengthened, and its anti-breaking ability has been improved to a certain extent, but its anti-dumping ability has not changed significantly.

Its shortcoming is that although it has played a certain role in strengthening the utility pole, due to structural limitations, its supporting area is small, and the effect of anti-dumping and breaking ability is not obvious
