On cushion block, described armored concrete bucker is the case structure with opening, opening up, described spherical rubber branch
Seat, cushion block, box waterproof skirtboard are located inside armored concrete bucker, the opening of armored concrete bucker and steel bridge pier it
Between connected with rubber fastening band, armored concrete bucker is internally formed sealing space；Described one-way water outlet valve group includes
Upper one-way water outlet valve and lower one-way water outlet valve, are connected between upper one-way water outlet valve and lower one-way water outlet valve by waterpipe, described
Unidirectional air inlet valve group include upper Unidirectional air inlet valve and lower Unidirectional air inlet valve, upper Unidirectional air inlet valve and lower one-way air inlet
Connected between valve by feed channel；Described upper one-way water outlet valve and upper Unidirectional air inlet valve are separately mounted to rubber fastening band
On, described lower Unidirectional air inlet valve is arranged on the top plate of box waterproof skirtboard, and described lower one-way water outlet valve is arranged on case
On the side wall of type waterproof skirtboard.
Described rubber fastening band upper surface sets galvanized steel plain sheet, and rubber fastening band is fixed on reinforcing bar by fastening bolt to be mixed
In the opening and steel bridge pier of solidifying soil bucker.
Beneficial technique effect：
The air-tightness steel bridge bearing waterproof construction that the present invention is provided, by armored concrete bucker and bridge lower junction
Rubber fastening band is set between structure, can effectively anti-water-stop body enter bucker space in, by box beam bottom set box
Skirtboard, it is ensured that under the conditions of rubber fastening band partial failure, the water body liquid level into armored concrete bucker is located at
Below bearing liner plate, bearing will not be by influence on water body.
The air-tightness steel bridge bearing waterproof construction that the present invention is provided, by being protected in first layer --- rubber fastening band and
Two layers of protection --- set between box waterproof skirtboard it is independent it is unidirectional calm the anger and discharge pipe line, enter in armored concrete bucker
During water can easily by the method for from the injecting compressed air to air pipe by the water body in armored concrete bucker from
In discharge pipe line discharge, with it is easy to maintenance the characteristics of.
The air-tightness steel bridge bearing waterproof construction that the present invention is provided, simple in construction, easy construction, with very high practical valency
Value.
