Abstract

The invention relates to an overhead line apparatus for power communication transmission, in particular to a concrete electric pole used for erecting a transmission line and a production process thereof. The electric pole comprises a concrete pole body and a steel reinforcement cage buried in the pole body. The concrete pole body is of a cone shape of which the conical degree of the concrete polebody is 1:75. The head of the concrete pole body is provided with an end cover. The steel reinforcement cage is formed by binding a plurality of main reinforcements, internally spiral reinforcements and externally spiral reinforcements which are equal in length. The main reinforcements are uniformly distributed in the annular side wall of the concrete pole body with the central line of the concrete pole body as an axis. The internally spiral reinforcements and externally spiral reinforcements are uniformly wound and distributed on the inner and outer sides of the main reinforcements with the central line of the concrete pole body as an axis as well. A concrete protective layer of the steel reinforcement cage in the concrete pole body is no less than 10mm.

Description

[technical field [0001] The invention relates to an overhead line equipment for power communication transmission, in particular to a concrete pole for erecting a power transmission line and a production process thereof. 【Background technique】 [0002] The structure of traditional prestressed concrete poles generally consists of main reinforcements of equal length, plus a number of non-prestressed reinforcements evenly arranged on vertically distributed erecting rings, and then external spiral reinforcement is wound outside the main reinforcements to form a reinforcement cage. Afterwards, after pouring the concrete again, it forms a kind of prestressed concrete electric pole and its production process disclosed in the patent literature as the Chinese patent application number 200710027089. Segmented structure; concrete grout is poured into the mold by the steel cage, and after centrifugal molding and steam curing, it is formed into reinforced concrete above C80 grade. Among ...
