AI Technical Summary

Technical Problem

In existing technologies, drainage pipes inside dams are easily damaged by swaying and pressure, and the vibration generated when water flows through them may cause the pipes to break, affecting the stability and durability of the drainage structure.

Method used

An enclosure is set up inside the dam body, and a pumping mechanism and water delivery pipe are arranged inside the enclosure. The water delivery pipe is limited and vibration-damping supported by a buffer structure to form a relatively independent protective space, reducing the impact of water flow vibration on the pipeline. The vibration is absorbed by the buffer structure and rubber rings to reduce the risk of friction and compression.

Benefits of technology

This effectively prevents pipes from shaking and rubbing in the backfill layer, improves the stability and durability of the drainage structure, reduces the risk of pipe breakage, and enhances the reliability of equipment operation.

Abstract

The utility model relates to drainage technical field, concretely relates to a dam body drainage structure, including dam body ontology, the dam body ontology inside is equipped with the accommodation room, the accommodation room one end is linked with outside, be equipped with pumping mechanism in the accommodation room, pumping mechanism one end is connected with the pump water pipe, the other end is connected with the water delivery pipe, the outer wall of water delivery pipe with the inner wall of accommodation room is equipped with the buffer structure, through setting up the accommodation room of communication with outside in the dam body ontology inside, and arranging pumping mechanism in the accommodation room, water delivery pipe is arranged in the accommodation room, and the buffer structure is arranged between the outer wall of water delivery pipe and the inner wall of accommodation room, makes water delivery pipe effectively limit and damping support in the drainage process, reduces the influence that the vibration of water flow generates when passing to the pipeline, avoids the pipeline to shake and rub with surrounding material in the filling layer, thereby reduces the pipeline fracture risk.
