Due to the limitations of urban construction sites, more and more shield construction adopts the split starting method. During the split starting stage of the shield, the shield machine head needs to be disconnected from the rear supporting trolley and the trolley is placed on the ground. The required power, communication, grouting and other pipelines need to be extended from the rear supporting trolley on the ground to the shield machine. As the shield machine head advances into the tunnel, the rear pipeline needs to be extended accordingly. The previous processing method requires a large number of manual handling of the pipelines to extend forward with the shield excavation, which has low construction efficiency and high construction costs. In addition, there are many pipelines, which are easy to mix and there is a great safety risk when they are piled on the ground.

[0003] Therefore, the water pressure test of large-diameter water supply steel pipes requires a detachable back device with the following characteristics: 1) It can efficiently transport the pipeline and has sufficient bearing capacity; 2) The overall form is modular, which is convenient for rapid installation, dismantling and transportation, and can reduce construction time; 3) The device can be reused to reduce construction costs; 4) It is highly safe and reduces pipeline wear, so as to solve the above problems.
