Description
Technical field
The invention belongs to power industry electrical network electricity consumption tower technology field, be specifically related to a kind of triangular section electric power pylon.
Background technology
Along with the high speed development of power grid construction, being becoming tight line corridor day, transmission line of electricity is limited by external condition, high-tension electricity
The net problem by way of mining influence district is outstanding day by day.Mining influence district leaves large-area mined out Mian Ji lane after referring to mining
Road, due to the time that complex geologic conditions is changeable, size pit mining method Exploitation Status various, multiple influences each other or exploits
The not equal reason of process and depression situation, makes covering layer on ore body lose support, and surrounding rock body loses original poised state,
Produce bending or fracture therewith, cave in, cause earth's surface to produce differential settlement.At present, China's ultra-high-tension power transmission line self-supporting
The cross section of steel tower tower body is square, and four-point supporting is redundant structure, and the differential settlement of four lower limbs will make component not
Evitable generation retrains secondary stress.And it is general the biggest to retrain secondary stress, the most then make steel tower that substantially deformation occurs, heavy then make office
Portion's component destroys, the safe operation of serious threat transmission line of electricity.After monitoring steel tower deformation, general employing " lengthens ground
Foot bolt protruded length " and the method for " replacement column foot ", by hydraulic jack, jacking tower leg adds pad or replaces new tower
Foot, makes shaft tower restore to the original state as far as possible.Steel tower deformation method for correcting error of this type of " first run, afterwards administer " the most costly, effect
The poorest, and operation under electrification in high voltage, implement difficulty and greatly and there is obvious potential safety hazard.Therefore, exploitation one adopts shadow
Ring the technical scheme that the newly-built electric power pylon in district is suitable for, to ensureing that line security operation, expanding economy and society stablize, all have
Important meaning and practical engineering application is had to be worth.
