The water supply and drainage pipeline engineering is a pipeline system engineering for conveying and distributing industrial water supply and domestic drinking water and collecting, conveying and discharging industrial wastewater, domestic sewage and rainwater. The water supply and drainage pipeline engineering is an integral part of a water supply and drainage system, plays an important role in the whole water supply and drainage system, and comprises the pipeline system, various structural engineering on the pipeline system and the like. The ribbed pipe is commonly used in the market at present as a water supply and drainage system pipeline, and is characterized in that the outer wall of the pipe is provided with radial reinforcing ribs, so that the ring stiffness of the pipe is improved, the thickness of the pipe wall can be reduced under the condition of meeting the requirement of the same bearing strength, and the impact resistance is improved under the condition of realizing the effect of saving materials.

The pipeline connection mode comprises hot melt connection and socket joint connection, and because the construction operation is relatively complex and the construction efficiency is low, socket joints are generally adopted on site to be relatively more. At present, the drainage pipeline which is connected by the socket joint of the sealing ring is mostly adopted in water supply and drainage engineering, a larger gap is left between the socket and the spigot in consideration of the factor of convenient installation, and the connection is realized by simply inserting the spigot with the sealing ring into the socket. After the pipeline is filled with soil and backfilled, the bell and spigot is deformed by extrusion force, the compression amount of the rubber ring in the bell and spigot is inconsistent after the rubber ring is extruded, water can easily leak from a loose part, the ground can be collapsed due to water leakage, and great potential safety hazards exist.

During connection, because the rubber ring is difficult to fix and the socket force controls deviation, the pipeline joint is easy to damage or the sealing is not tight, and water leakage is caused to seriously affect the engineering quality; because the protection measures are not in place or the connection is not timely, when the groundwater is high, a large amount of silt often flows into the pipe, so that rework and loss are caused.
