Abstract

The invention discloses an annular concrete pole and a segmented assembling method thereof. The annular concrete pole is composed of multiple segments of branch pole bodies. Multiple columnar holes are formed in the axial direction of the top end face of each segment of branch pole body. Threaded grooves are formed in the hole walls of the columnar holes. Multiple inserting rods are arranged on the bottom end face of each segment of branch pole body. The positions of the inserting rods are in one-to-one correspondence to the positions of the columnar holes. Each inserting rod is composed of aninner core shaft and an outer shaft sleeve, the inner core shafts are fixedly connected with the bottoms of the branch pole bodies, the inner walls of the outer shaft sleeves are rotationally connected with the inner core shafts, and the outer diameter of each outer shaft sleeve is equal to the inner diameter of each columnar hole. Threaded strips are arranged on the outer walls of the outer shaft sleeves and can be completely screwed into the threaded grooves. According to the annular concrete pole, the segmented assembling method is adopted, transporting is convenient, and the field construction difficulty is reduced; and during assembling, only the branch pole bodies need to be lifted and aligned, threaded connection of adjacent segments can be completed through the self gravity of thebranch pole bodies, connecting firmness is guaranteed, and the field assembling efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of power poles and towers, in particular to an annular concrete pole and a segmented assembly method thereof. Background technique [0002] In recent years, with the rapid development of my country's electric power industry, urban and rural industrial and agricultural development has higher and higher requirements for power transmission and distribution lines. Due to the continuous improvement of voltage levels and fluxes, new and higher requirements have been put forward for concrete pole products technical requirements. In the design of overhead transmission and distribution lines, the selection of pole types is generally divided into three types: iron towers, steel pipe poles and concrete poles. However, due to the poor corrosion resistance of iron towers and steel pipe poles, high cost, short service life, large footprint, cumbersome installation process, and long construction period, similar steel struc...
