In the opening and steel bridge pier for coagulating native bucker.
Beneficial technique effect：
Air-tightness steel bridge bearing waterproof construction provided by the utility model, by under armored concrete bucker and bridge
Rubber fastening band is set between portion's structure, can effectively anti-water-stop body enter bucker space in, by box beam bottom set
Box skirtboard, it ensure that under the conditions of rubber fastening band partial failure, into the water body liquid level of armored concrete bucker
Below bearing liner plate, bearing will not be by influence on water body.
Air-tightness steel bridge bearing waterproof construction provided by the utility model, by being protected in first layer --- rubber fastening band
Protected with the second layer --- set between box waterproof skirtboard it is independent it is unidirectional calm the anger and discharge pipe line, in armored concrete waterproof
Can be easily by the method for from the injecting compressed air to air pipe by the water in armored concrete bucker during cover water inlet
Body is discharged from discharge pipe line, has the characteristics of easy to maintenance.
Air-tightness steel bridge bearing waterproof construction provided by the utility model, it is simple in construction, it is easy for construction, there is very high reality
With value.
