The Prestressed Concrete Cylinder Pipe (PCCP) is widely applied to water delivery and water transfer projects at home and abroad due to the superior performance and higher cost performance. Prestressed wire breakage is the most common disease of PCCP, and common repairing and reinforcing methods comprise excavation maintenance and trenchless maintenance. The water delivery is interrupted to enter the pipeline for repair construction without excavation repair, the construction period is long, the broken wire pipe section needs to be exposed by excavation for excavation repair, and the water delivery can be uninterrupted. On the whole, because the PCCP is mostly used for long-distance water transmission main pipes, and the water cut-off maintenance seriously influences the daily life water of urban residents, the PCCP maintenance mostly adopts an excavation non-water cut-off maintenance method at present, however, because the diameter of the PCCP is large, the PCCP is mostly connected in a socket joint mode, if the suspended pipe sections cannot be effectively supported in the excavation maintenance process, the pipe joints are easily damaged, and even pipe burst accidents occur. Therefore, it is necessary to develop a fast and efficient PCCP pipe joint supporting device.

Detailed Description
As shown in figure 1, strutting arrangement is restoreed in PCCP pipeline excavation, includes arc steel sheet support 6 and jack, and the radian of arc steel sheet support 6 is laminated with 1 external diameter radian of PCCP pipeline to make PCCP pipeline 1 can receive stable even jacking force, arc steel sheet support 6 is located PCCP pipeline 1 below. Support brackets 7 are arranged at two ends of the arc-shaped steel sheet support 6, a jack 10 is supported below the support brackets 7 in a matched mode, specifically, a clamping groove 8 is formed in each support bracket 7, an end head 9 is arranged at the top of the jack 10, the end head 9 is matched in the clamping groove 8, and the jack 10 is supported below the support brackets through the matching of the clamping groove and the end head. The bottom of the jack 10 is connected with a steel plate 11, and the steel plate 11 is connected to a supporting device bottom plate 13 through a bolt 12.
A jack 10 is matched below each support bracket 7, the two jacks 10 are synchronous jacks, the two jacks 10 can be synchronously jacked, a force sensor is arranged in each jack 10, and jacking force of the PCCP pipeline 1 is controlled in the jacking process of each jack 10.
The supporting device bottom plate 13 is high elastic die steel material that is difficult for taking place to warp, is provided with support earthwork 4 below the supporting device bottom plate 13, and sets up on supporting earthwork 4 in the centering of supporting device bottom plate 13, and the seam crossing of two sections PCCP pipeline 1 is tube coupling 3, supports earthwork 4 and is located under tube coupling 3.
The use process of the supporting device 5 is as follows:
(1) excavating the pipe section at the broken wire part of the PCCP pipeline 1 until the distance is 15mm from the bottom of the PCCP pipeline 1, stopping excavating, wherein the distance 15mm from the bottom of the PCCP pipeline is a first excavation reference surface, continuing excavating after the first excavation reference surface is excavated, excavating supporting earthwork 4 right below the pipe joints, and tamping the supporting earthwork 4;
(2) placing the support device bottom plate 13 on the support earthwork and centering the support device bottom plate so that the support device bottom plate is placed at the center of the upper plane of the support earthwork;
