[0002] Ductile cast iron pipe has the advantages of good tensile strength and pressure resistance, strong anti-seismic and foundation settlement resistance, convenient installation, strong corrosion resistance, good sealing, long service life, low construction cost and high detectability, and is widely used in urban water supply and drainage pipeline systems. Ductile cast iron pipes are generally connected by socket joints. The main advantages of socket joints are convenient and fast connection, good sealing performance and high connection efficiency. However, the axial tensile and transverse bending resistance of socket joints are insufficient, so a sand foundation with a certain compaction coefficient is required when ductile cast iron pipes are buried, and a support pier is required at the joint when the pipes are overhead.
[0003] When the pipe sand foundation or support pier is damaged, the joint position will be suspended, and the socket connection position will be prone to deformation and rupture under the action of the pipe's own weight, which will cause leakage of the medium in the pipe, affecting the normal operation of the pipe and possibly causing damage to construction personnel and facilities. Therefore, when the pipe is suspended, the suspended pipe needs to be supported and reinforced as soon as possible. The commonly used reinforcement method requires a large amount of manpower and mechanical equipment, and the construction speed is slow and the efficiency is low, which cannot achieve the purpose of rapid support and rescue.
