The invention provides a circular pipe culvert construction lifting appliance and a lifting method.The circular pipe culvert construction lifting appliance comprises a longitudinal rod, a lifting rod, a supporting rod and a bottom rod, the lifting rod, the supporting rod and the bottom rod are sequentially and fixedly arranged on one side of the longitudinal rod from top to bottom in parallel, supporting plates are evenly arranged on the two sides of the supporting rod, and one end of each supporting plate is hinged to the side face of the supporting rod; a supporting plate adjusting mechanism used for adjusting vertical swing of the supporting plate is arranged at the bottom of the supporting rod. A limiting mechanism is arranged at the end, away from the longitudinal rod, of the supporting rod. According to the lifting device, the supporting plate is vertically swung and adjusted through the supporting plate adjusting mechanism, so that the supporting plate is matched with the radian of the inner side of the circular pipe culvert, the contact area between the supporting plate and the inner side of the circular pipe culvert is increased through the supporting plate, stress on the inner side of the circular pipe culvert is dispersed, damage to the inner side of the circular pipe culvert in the lifting process is avoided, and meanwhile the lifting stability is improved.

    本发明提供一种圆管涵施工吊具及吊装方法,圆管涵施工吊具,包括纵杆,所述纵杆的一侧由上至下依次固定设置的相平行的吊杆、托杆及底杆,所述托杆的两侧均匀设置有托板,所述托板的一端与所述托杆的侧面相铰接,所述托杆的底部设置有用于对所述托板上下摆动调节的托板调节机构;所述托杆上背离所述纵杆的一端设置有限位机构;本发明中,通过托板调节机构对托板上下摆动调节,使托板与圆管涵的内侧弧度相匹配,通过托板增大与圆管涵内侧之间的接触面积,分散圆管涵内侧受力,避免在起吊过程中对圆管涵内侧造成损坏,同时提升起吊稳定性。
