Description

Water pumping pipeline for water conservancy tunnel Technical Field The utility model relates to the technical field of pipelines, in particular to a water pumping pipeline of a water conservancy tunnel. Background The water conservancy tunnel occupies an important position in modern water conservancy projects, and is a key infrastructure for realizing the functions of reasonable water resource allocation, flood control, drainage, hydropower development and the like. In the operation process of a water conservancy tunnel, water pumping operation is an extremely important link, and the timely drainage of accumulated water in the tunnel is related to ensure the safety of a tunnel structure and the normal operation of equipment. The water pumping pipeline of the water conservancy tunnel is used as a core component of water pumping operation, the performance quality of the water pumping pipeline directly influences the efficiency and the stability of the water pumping operation, and the water pumping pipeline plays a decisive role in the reliable operation of the whole water conservancy tunnel system. In the existing water conservancy tunnel pumping pipeline technology, the connection stability between pipelines is a key problem. Conventional pipe connection methods generally rely on simple sleeving or welding means. When the sleeving manner is adopted, in the long-term pumping process, the pipeline joint is easily loosened due to the impact and vibration of water flow and the external force influence caused by the complex geological environment in the tunnel. The water leakage type tunnel structure is characterized in that the sleeve connection cannot effectively limit the relative displacement between the pipelines in all directions, the acting force generated by water flow impact can gradually increase the gap at the joint, the connection is invalid, the water pumping efficiency is reduced, the water leakage problem is possibly caused, and the tunnel structure is damaged. While the welding connection enhances the connection strength to a certain extent, in practical construction, the welding quality is difficult to be completely ensured, and the risk of welding defects exists.
