Background
Pipe jacking construction is an underground engineering construction method developed following shield construction, and a pipe jacking machine is main construction equipment of the method. The main principle of the pipe jacking machine construction is that the pipe joint and the pipe jacking machine are pushed together to penetrate through the soil layer from the working well and are lifted in the receiving well by means of the thrust of the main jacking oil cylinder. In the construction process, new pipe joints are required to be continuously placed into the working well along with the forward propulsion of the pipe joints and the pipe jacking machine. The new pipe joint is lowered generally by fixing the pipe joint with a special pipe joint lifting tool, then lifting the pipe joint lifting tool by a crane through a steel wire rope and other devices, lowering the pipe joint to a specified position, then separating the pipe joint lifting tool from the pipe joint, enabling a main jacking cylinder to act on the new pipe joint, and enabling a pipe jacking machine to start forward tunneling. At present, the commonly used tube push bench mainly has two types of circular and rectangular. The rectangular pipe jacking machine is higher in section space utilization rate, widely applied to underground space construction of subway station access & exit, underground comprehensive pipe gallery, underground parking garage and the like, and correspondingly, the pipe joint used for rectangular pipe jacking machine construction is also rectangular. The traditional rectangular pipe section lifting appliance comprises a cross beam, lifting rings fixed on the upper portion of the cross beam, a pair of lifting arms symmetrically arranged at two ends of the cross beam, a steel bar arranged at the lower end of the lifting arms and a steel bar limiting device. In the process of fixing and loosening the pipe joints, the steel bar needs to be repeatedly inserted and pulled out, the weight of the steel bar is large, great manpower and time are consumed in the process, and the working efficiency is reduced.
