Bridge tower cantilever gradient concrete synchronous construction method
The invention discloses a bridge tower cantilever gradient concrete synchronous construction method. A bridge tower consists of a cantilever at the upper part and a support at the bottom part, wherein the cantilever inclines to midspan and comprises two layers of concrete structures, namely an inner layer concrete structure and an outer layer concrete structure, and the strength of the outer layer concrete structure is larger than that of the inner layer concrete structure, during pouring gradient concrete, 50cm of outer layer concrete is first poured, and 30cm of inner layer concrete is then poured, after performing synchronous vibration, under the condition of keeping 20cm of altitude difference of the inner and outer layers, the pouring and vibration are performed upwards synchronously layer by layer until the pouring of the bridge tower is completed. The bridge tower cantilever gradient concrete synchronous construction method provided by the invention has the advantages that the adaptability is good, the structure is simple, the manufacturing is convenient, the operability is good, safety and reliability are realized, the economy is good, and the application prospect is good.
