Description

Technical Field

[0002] The purpose of water conservancy projects is to control surface water and groundwater in order to achieve the goal of eliminating harm and promoting benefits. Water conservancy projects can prevent floods and waterlogging disasters by controlling water flow. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's life and production for water resources. The construction of water conservancy projects requires water conservancy pipes to facilitate the control of water flow. A large number of right-angle pipes will be used in the process of assembling water conservancy pipes.

Due to the characteristics of the right-angle pipe, the silt is more likely to accumulate at the corners, resulting in blockage in the right-angle pipe after long-term use. Once the right-angle pipe is blocked, it is difficult to clean. At present, the staff generally disassembles the right-angle pipe and then cleans the inside of the right-angle pipe, which makes the cleaning process more cumbersome. Utility Model Content
