Combined mold for box column grouting

The utility model discloses a combined die for grouting a box column, which comprises a concentric-square-shaped limiting pouring box, and a vibration steel pipe limiting structure is mounted on the concentric-square-shaped limiting pouring box; the utility model relates to the technical field of cement column grouting, cement in the concentric-square-shaped limiting pouring box is subjected to sound wave vibration through the vibration steel pipe limiting structure, bubbles in the cement are vibrated out through sound wave vibration, unnecessary stress generated by the cement due to too many bubbles in the cement is avoided, the hardness of the cement is enhanced, and the service life of the cement is prolonged. And meanwhile, through the damping assembly, the phenomenon that the square-hole-shaped limiting pouring box shakes, and cement forming deviates is avoided. 本实用新型公开了一种箱型柱灌浆用组合模具，包括：回形限位浇注箱，所述回形限位浇注箱上安装有限位结构以及震动钢管限位结构；本实用新型涉及水泥柱灌浆技术领域,通过震动钢管限位结构将回形限位浇注箱内的水泥进行声波震动，通过声波的震动将水泥内的气泡震动出来，避免了水泥内的气泡过多，使得水泥的产生
