Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering construction, and more specifically, to a tooling for fixing a pump pipe in the inner cavity of a hollow high pier. Background Art

[0002] The construction of hollow high piers generally adopts the construction technology of flip mold or hanging formwork. The segment height is generally 4.5m or 6m. When pouring concrete, a high-pressure pump pipe needs to be extended from the outside of the uncast segment template into the center of the section, and a rotating flange is used to match the string tube for material distribution. During the construction of hollow high piers, due to the high segment height, large cross-sectional size and the fact that the pump pipe is only constrained at the previous segment, the concrete output end has a large degree of freedom, which can easily cause phenomena such as pipe jumping, pump pipe impacting the formwork, and unstable pumping pressure, causing a huge impact on the formwork support system, and multiple re-vibrations of the lower layer of concrete cause over-vibration segregation of the lower layer of concrete or cracks in the initial setting stage. The size and rigidity of traditional inner cavity construction tooling are small, inconvenient to disassemble, and the overall cost is high. In addition, it cannot provide a construction platform for high-altitude operations for pump pipe disassembly. In view of the problem of fixing the pump pipe in the inner cavity of hollow high piers, a safe, convenient and economical tooling is urgently needed to solve the shortcomings of the existing technology.
