Technical field:
The utility model relates to Temporary Piers counter-force the field of test technology, in particular to a kind of bridge construction stage Temporary Piers branch Counter-force monitoring device.
Background technique:
In bridge construction, the interim bridge pier set up for structure stress and safely is seen everywhere.Temporary Piers are as lower part The important component of support construction, its effect, importance and main pier have par during pushing tow.In girder steel pushing tow In the process, not only support reaction changes greatly Temporary Piers, and pressure pattern is changeable.No. 3 Temporary Piers of such as flat victory bridge are in girder Support reaction reaches maximum when pushing tow is to 165 operating condition, and value is 12000kN or so, in the 200th~the 285th operating condition of girder pushing tow When support reaction be zero;For the L2 Temporary Piers of two or seven Yangtze Bridge when girder is total to pushing tow 140m operating condition, girder is to L2 Temporary Piers slideway Pressure be uniformly abound with slideway length, but when girder is total to pushing tow 180m operating condition (not crossing pier), girder is to L2 Temporary Piers slideway Pressure is two-fold line load and load length only has 80cm or so.
On the other hand, although having carried out intensity and stability meter to interim pier structure in main beam supporting or before pouring Calculate, but engineering in practice, often due to exploration is insufficient, so that how much the parameter and theoretical value of the soil body will appear deviation.For For the sake of safety, the bridge construction being placed on for a long time on Temporary Piers especially for girder very must to the monitoring of Temporary Piers counter-force It wants.The construction technology in China realized rapid development in recent years, but to still no at present specific of the monitoring of Temporary Piers counter-force Method.
Summary of the invention:
The purpose of this programme is to provide a kind of bridge construction stage Temporary Piers support reaction monitoring device, to solve due to calculating Error and the excessive bring damage of support reaction caused by the different construction stages.
