Description
Technical field
The present invention relates to power transmission and transformation power line construction technical fields, are not only restricted to draw at the top of pole more particularly to one kind
The method for assembling of the UHV transmission steel tower suitable for mountain area sternness location of line unfolding.
Background technique
Tower erection construction is important link in transmission line construction, great in constructing amount, security risk is high.For Zang Dong,
The western high mountain in river, uplift plateau equal ripple drop are big, ravines and guillies criss-cross, the special construction environment with steep cliff, steep bank, because of the bracing wire of pole top
It can not unfold, the group for usually limiting UHV transmission steel tower stands the development of work.
Supertension line tower erection itself is installed there are the boom of pole and dismounting is inconvenient, hoisting weight is big, Zong Xianggao
Big, Hoisting Position is spent far from problems such as steel tower centers.
In addition, on the one hand since the research of the vertical technique of extra-high voltage iron tower group is rarely found in the prior art；On the other hand existing
There is combined pole to be essentially the straight bar section using the connection of multiple standard components, generallys use interior suspension in tower erection construction
External cable formula pole split tower erection or inner suspended inner guy formula pole split tower erection, it is very big that the former is in height difference variation for tower position
Butte, halfway up the hill even precipitous cliff area etc. be not easy to the place of bracing wire, landing external cable over the ground horizontal plane angle it is difficult to ensure that not
Greater than 45 °, the latter is it is difficult to ensure that the stability lifted, therefore, prior art location group severe for steep cliff, steep bank etc. are stood extra-high
Pressure electric power pylon difficulty has reference place.
