Description

A kind of bridge static loading test automaton and autocontrol method
Technical field
The present invention relates to bridge quality test equipment technical field, be specifically related to a kind of bridge static loading test automaton and autocontrol method.
Background technology
At home in high speed railway construction, the ratio shared by bridge is more and more higher, precast beam about 85%, Cast-in-situ Beam about 5% ~ 10%, and the quality of bridge is directly connected to railway operation safety, closely related with the life security of national wealth and the people.The security of bridge and not easily replaceability is most important.Therefore, design and standard-required bridge must 100% reach the century-old life-span.
At present, bridge static loading test is the only resource of evaluation bridge usability.Reach the requirement in century-old life-span in order to ensure bridge quality 100%, require that bridge static loading test must ensure to load accurately, it is correct to judge, test figure is true and reliable and record complete.Once static test generation error of test data is excessive or distortion, misregistration or omission, then can not the result of actual response beam static test, misjudgement will be caused or fail to judge, and immeasurable heavy economic losses must be caused to country and enterprise, also will cause bad impact to society.Highway beam, because not doing static test, causes the situation rupturing or collapse of common occurrence.Therefore, the requirement in strict accordance with TB/T 2092 " prestressed concrete railway bridge free beam dead load bends experiment method and evaluation criteria " is carried out precisely synchronously loading inspection to bridge, retains complete test data sheet and seems particularly important.
Although we have bridge static loading test standard, the bridge static loading test add load control do not matched with testing standard.A kind of method that simultaneously can realize the automatic control bridge static loading test of sync equalizing loading and dynamic auto balance is not had yet.For many years, railway expert is also exploring always and how to develop special bridge static loading test and load automaton, is difficult to control, each load(ing) point load can not automatic adjustable balance and can not the backward situation of data upload to change the sync rates loaded in current static test simultaneously.
In practice, there is following weak point in existing bridge static loading test apparatus and method:
(1) in load phase, be difficult to realize ten oil pumps and be synchronously loaded into same load.The two ends that when namely loading, reaction frame arches up and test beam lower flexure strain is little load fast, are out of shape large span centre and load slow, and mutually disturb between each load(ing) point.Holding the lotus period, because trial load causes the distortion that reaction frame arches up and test beam downwarp causes at each load(ing) point different, each load(ing) point payload values is caused to produce different decline, the respective ftercompction in limited time of each load(ing) point load, mutually to disturb, be difficult to adjustment balance, can not ensure to remain on the payload values of test determination holding each load(ing) point in the lotus time, namely repeatedly adjust holding each load(ing) point in the lotus time, test actual loading does not reach calculating load always.This is that static test guarantees loaded value accurately and the most scabrous problem.
(2) existing static test calculate single, test loads, hold lotus time, deflection metrology reading, provide test report etc. all by manual operation, deviation and mistakes are unavoidable.Once there is the situation artificially adjusting demarcation sensor, deflection value error in reading, artificial amendment test figure and make up static test report.Therefore, existing static-load testing device and Static Load Test Method cannot be monitored deviation, mistake, fraud.Once Carrying Capacity appears in bridge, bring about great losses to people's life safety and national wealth.
(3) because the installation deviation of reaction frame and lifting jack and reaction frame arch cause Qian Jin Ding Transverse beam corner, jack piston piston is made to produce side force, cause frictional resistance to increase, it is less than normal that the lifting jack causing pressure gauge reading to show loads force value, namely tests actual loading and do not reach calculating load.
(4) data upload and remote monitoring can not be realized because of the complete manual operation of bridge static loading test.
(5) process of the test is completed by manual operation and the manpower of at substantial completely.As the calculating of the supporting demarcation of loading equipemtn and linear regression before test, each jack oil meter reading, static test calculates single, test and loads, holds lotus time, deflection metrology reading, provides test report etc.Be loaded as example with double line box girder 10, pumper 10 people, prison table 10 people, dial gauge amount of deflection reading 6 people, separately need be equipped with commander in chief 1 people, timekeeper 1 people, gap observation 6 people, equipment safety supervision 1 people, amount to 35 people.
(6) be loaded as example with double line box girder 10, need 10 oil pumps, expend equipment purchasing fund, and 10 oil pumps are difficult to synchronous loading.
In sum, in order to bridge static loading test realizes synchronous loading and each load(ing) point load self-poise, warranty test data true, accurate, reliable, improve automaticity, reduce experimental labor and equipment, realize test figure and upload and remote monitoring, need to develop a kind of device that can realize automatically controlling bridge static loading test, meanwhile, also need to develop a kind of method that simultaneously can realize the bridge static loading test of sync equalizing loading and dynamic auto balance.
