Pouring device and method for steel shell-concrete composite orthotropic bridge deck slab structure
The invention belongs to the technical field of bridge engineering, and particularly discloses a pouring device and method for a steel shell-concrete composite orthotropic bridge deck slab structure. Comprising a discharging hopper, a shaping discharging section, a transition section and vibrators, the multiple vibrators are arranged in the transverse bridge direction and the longitudinal bridge direction, the multiple vibrators in the transverse bridge direction are synchronous, partition variable-frequency vibration in the longitudinal bridge direction is synergistic, and the frequencies of the vibrators are gradually reduced from bottom to top, so that the frequencies of the vibrators and a flow-state concrete mixture resonate; the steel shell concrete composite orthotropic bridge deck slab structure can stimulate the thixotropic property of the flow-state concrete, so that the flow velocity of the concrete mixture in each section of the steel shell concrete composite orthotropic bridge deck slab structure is equal, the cooperation of the vibration frequency and the flow velocity is realized, and the concrete mixture can continuously, uniformly and stably flow downwards. Through reasonable arrangement of the vibration exciters, resonance is formed between the vibration exciters and the filled concrete, the thixotropic performance of the vibration exciters is brought into full play, the flowability of the concrete is remarkably enhanced, and the problem of concrete pouring in a narrow space is solved.
本发明属于桥梁工程技术领域，并具体公开了一种钢壳‑混凝土复合正交异性桥面板结构的浇筑装置及方法。包括下料斗、整形下料段、过渡段和振动器，所述振动器沿横桥和纵桥方向布置多个，横桥方向多振动器同步、纵桥方向分区变频率振动协同，由底部向顶部逐渐减小振动器频率，使得振动器频率与流态混凝土拌合物共振，以激发流态混凝土的触变性能，使混凝土拌合物在钢壳混凝土复合正交异性桥面板结构的各个区段的流速相等，实现振动频率与流速协同，混凝土拌合物可以持续均匀稳定地向下流动。本发明通过合理的激振器布置，与内填混凝土形成共振，充分发挥其触变性能，显著增强了混凝土的流动性，解决了狭小空间混凝土浇筑的问题。
