Electric power wind-resistant and overturn-preventing straight electric pole foundation

Abstract

The invention provides an electric power wind-resistant and overturn-preventing straight electric pole foundation. The electric power wind-resistant and overturn-preventing straight form electric polefoundation is arranged underground and used for supporting an electric pole to enable the electric pole to have higher wind resistance, overturn-preventing capacity, pulling resistance and the like,;when the electric pole is changed or a circuit is transferred later, the foundation can be repeatedly used without investment waste. The electric power wind-resistant and overturn-preventing straightelectric pole foundation is characterized in that a thread is formed in the external part of the foundation; a bellmouth and a mud outlet connected with a cylindrical hole are formed in the lower surface of the interior of the foundation; an inverted trumpet shaped counterbore is formed the upper surface of the interior of the foundation; positioning bolts are arranged on the periphery of the upper surface of the inverted trumpet shaped counterbore; the foundation is put on the ground, then, the base is rotated to automatically bury the foundation underground, and mud extruded out of the mudoutlet is automatically compressed and formed; an electric power pole is inserted in the inverted trumpet shaped counterbore, the lower end of the electric power pole is clamped at the bottom of the inverted trumpet shaped counterbore, the perpendicular degree of the electric power pole is adjusted through the positioning bolts on the upper side, then, a wedge block is put in the inverted trumpetshaped counterbore to further fix the electric power pole, and finally, the cylindrical hole is filled with mud.

Description

technical field [0001] The invention relates to an electric pole foundation. Background technique [0002] The pole tower is the general term for the pole and the iron tower. It is vertically arranged on the ground as a support device for the overhead line. Keep a certain safe distance between objects; the underground devices of the tower are collectively called the foundation, and the foundation is used to stabilize the tower so that the tower will not be pulled up, sinking or toppled due to vertical load, horizontal load, accidental disconnection tension and external force. [0003] The excavation of the traditional power grid pole foundation usually requires two people to use a "shovel and scoop" to excavate a foundation pit with a depth of about 2 meters. It takes 4 hours to complete, which is inefficient and consumes too much physical strength of the workers. Large, in the case of water accumulation in the foundation pit, use the water and mud scooped out when digging ...

AI Technical Summary

Problems solved by technology

When the traditional power grid pole foundation does not meet the windproof requirements, the windproof reinforcement measures adopted have different degrees of advantages and disadvantages. For example, the installation of windproof pull wire measures has a better effect on the overall reinforcement of the pole, but it needs to occupy a large area of ​​the ground. Land acquisition Difficult, some on-site conditions make it difficult to implement and affect the appearance; if the sleeve foundation of the pole is added, the overturning resistance of the foundation is better, but it is necessary to pull out the pole and bury the sleeve foundation and then re-lift the pole, which requires a power outage. Moreover, the sleeve foundation lacks an adjustment mechanism, which makes it difficult to correct the poles; if the cast-in-place concrete foundation for the poles is added, the foundation and the poles will be integrated after construction. When the poles are replaced or the lines are moved later, the foundation cannot be reused. waste of investment

In addition, there are many types of poles in the distribution network because the foundation does not meet the windproof requirements, and the problem of land acquisition often becomes a difficult problem that restricts the windproof reinforcement of the poles, so there is always the risk of serious damage after the typhoon comes.
