Description
Technical field
The present invention relates to a kind of pylons to deviate dynamic observation system, especially a kind of based on ultrasonic displacement sensor
Pylon adjusts cable system 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, the bridge of rich Sha County Yongdinghe River 7 of the main span 150m built for 1966
It is the concrete arch-type bridge of largest domestic span at that time.China is concentrated mainly on construction method for the research of concrete arch-type bridge
Optimization aspect.With non-support cable crane system method, limited bracket construction method, cantilever-construction, construction by swing, Synchronous lifting
The successive appearance of the construction methods such as method, stiff skeleton construction method, concrete arch-type bridge have welcome the spring of development.2007, China
Concrete arch-type bridge --- the white sand ditch 1# bridge of 150m has been built up using Hanging Basket cantilever pouring technology for the first time.However, using Hanging Basket
When cantilever pouring construction method pours arch ring concrete, the dynamic measurement of pylon offset and correction, knotted rope (anchor cable) are continuous pre-
It is tightly construction Difficulties and priority control technique.Do not had using common construction method practical to pylon offset and each Suo Li
The automatic collection of the data such as stress, 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.
