Description
Technical field
The present invention relates to a kind of pylons to adjust cable system and method automatically.
Background technique
After founding of New, with the rapid development of bridge construction cause, a large amount of arch bridge has been built successively.Concrete arch
Bridge is applied to earliest among the railroad bridge construction in China, and the bridge of rich Sha County Yongdinghe River 7 of the main span 150m built for 1966 is
The concrete arch-type bridge of largest domestic span at that time.China is concentrated mainly on the excellent of construction method for the research of concrete arch-type bridge
Change aspect.With non-support cable crane system method, limited bracket construction method, cantilever-construction, construction by swing, Synchronous lifting method, strength
Property the construction methods such as skeleton construction method successive appearance, concrete arch-type bridge welcome the spring of development.2007, China was for the first time
The concrete arch-type bridge of 150m has been built up using Hanging Basket cantilever pouring technology --- white sand ditch 1# bridge.However, being poured using Hanging Basket cantilever
When building construction method and pouring arch ring concrete, dynamic measurement and correction, the continuous preload of knotted rope (anchor cable) of pylon offset are to apply
Work difficult point and priority control technique.Do not had using common construction method to pylon offset and each Suo Li actual loading etc.
The automatic collection of data, entirely with manual control, error is big, and risk is high.
When general concrete Arch Bridge Construction arch ring is poured, the offset of pylon is all by total station or GPS positioning system
System assists rectifying a deviation using the Suo Li, jack stroke, cable wind rope that manually adjust knotted rope and anchor cable, the preceding card of work progress
Then knotted rope and the single preload of anchor cable steel strand wires are integrally adjusted rope with large-tonnage jack, need to meet arch ring simultaneously by formula jack
Linear and pylon is stablized, and mainly by artificial observation and record, the method defect is as follows:
1) husky top grand bridge arch ring is constructed using Hanging Basket cantilever pouring, in concreting process, due to concrete weight
The increase of amount, pylon can be tilted along axis into bridge, if monitoring is improper with observation measures, pylon has unstability risk, be made
At serious safe mass accident.
2) since the steel strand wires that knotted rope (anchor cable) uses use the single preload of preceding clip type jack, jack stroke is short, by
It is many and longer in steel strand wires, it needs to carry out jack repeatedly to fall to open, preload can be met, labor intensity is big, effect
Rate is low, high altitude operation, increases security risk, since successively to pre-tighten stress inconsistent for each steel strand wires when single preload, steel is caused to twist
Line discontinuity, practical not to be able to satisfy the identical pretightning force of each steel strand wires, there are risks in anchoring procedure.
3) construction period is long, construction efficiency is low.
Summary of the invention
It is an object of that present invention to provide one kind can be automatically performed each knotted rope, anchor cable steel strand wires set the pre- of initial tensioning force
Tight work, and cable system is adjusted automatically with a kind of continuous pylon for adjusting cable stretching function.
