Structure capable of preventing transmission line concrete pole from uplifting and construction method thereof

Abstract

The invention discloses a structure capable of preventing a transmission line concrete pole from uplifting and a construction method thereof. The structure capable of preventing the transmission line concrete pole from uplifting comprises a concrete pole, a fixed ring, a fixed stay wire, tires and hubs. The construction method of the structure capable of preventing the transmission line concrete pole from uplifting comprises steps: 1 a concrete pole pit is excavated on a position which embeds a concrete pole; 2 the tires which are not full of gas are matched with the hubs to mount, and are horizontally arranged on the bottom portion of the concrete pole pit; 3 the fixed ring is sleeved on the concrete pole; 4 the concrete pole is vertically arranged in the concrete pole pit; 5 the fixed stay wire is arranged; and 6 the tires are inflated, and then the concrete pole pit is filled with ackfill and is compressed to enable the tires to be a compressed state, thereby completing construction. The structure capable of preventing the transmission line concrete pole from uplifting and the construction method thereof fundamentally solve the problem that concrete poles are uplifted because soils are frozen in winter and molten in summer in northern area of China, are simple in structure and convenient to construct, low in material cost and short in construction period, and greatly reduce maintenance cost which are required for solving the uplifting problem of concrete poles.

Description

Technical field: [0001] The invention relates to a structure for preventing cement poles from being pulled up and a construction method thereof, in particular to a structure for preventing cement poles from being pulled up in power transmission lines and a construction method thereof. Background technique: [0002] Soil heaving and the existence of a certain thickness of permafrost are the prerequisites for the uplifting of cement poles on transmission lines. In recent years, my country's power infrastructure construction has developed rapidly, and the amount of projects for transmission lines passing through permafrost regions is increasing day by day. The phenomenon of pulling up, tilting or even falling of cement poles has become more and more serious, seriously threatening the safety of transmission lines. Safe and stable operation. [0003] In the northeastern and western alpine regions of my country, the methods of uplifting cement poles are still mainly used for reinf...

Problems solved by technology

In addition, there are methods such as anchoring the lower part of the cement pole to exert a downward force, adding a water-resistant layer on the surface of the cement pole to reduce the uplift resistance, and wearing "overshoes" on the cement pole...Although the above methods are all to a certain extent It reduces or solves the problem of pulling up the cement pole, but due to the limitation of the cost of funds and engineering, the shape of the cross-section of the cement pole and the geographical characteristics, the above method is difficult to promote on a large scale
