Standardised monopole strengthening

摘要

A monopole hollow strengthening tower is provided comprising stages that each comprise a pair of half-pipe sections that fit around the monopole. Each pair of sections is connected to the stage below and to each other. A first stage is connected to the footing of the monopole, a second stage is connected to the top of the first stage and includes cable ports. Subsequent stages extend above the second stage, finally there is a top stage which incorporates a clamping system to grip the monopole. This stage is the only stage above the footing where the monopole and the strengthening tower are in contact with each other. This results in minimisation of outages and disturbances, shortest timeframe, minimum strengthening and avoids significant enlargement of the monopole footprint

主权项

1. A monopole hollow strengthening tower comprising:
a plurality of stages, each comprising a pair of half-pipe sections adapted to fit around a monopole, the plurality of stages comprising: a first stage adapted to be connected to a footing of a monopole, wherein the footing for the monopole is strengthened by causing a concrete foundation around an existing footing and setting an upper level of the foundation at a first predetermined distance below a lowest cable tray, and, wherein the half-pipe sections of the first stage have a height equal to the first predetermined distance; a second stage adapted to be connected to a top portion of the first stage, the second stage comprising at least one cable port designed for a particular cabling requirement of the monopole; a third stage, wherein the half-pipe sections thereof have the same diameter as the half-pipe sections of the first stage; a plurality of subsequent stages, each subsequent stage adapted to be connected to a top portion of a preceding stage; and a top stage having a top flange, which incorporates a clamping system located on the top flange, such that the top stage is the only stage above the footing of the monopole where the monopole and the strengthening tower are in contact with each other when the monopole hollow strengthening tower is assembled.
