Description

Technical Field

[0001] This utility model relates to the field of flood control technology for dikes and dams, specifically to a device for guiding piping in water conservancy facilities. Background Technology

[0002] Piping refers to the phenomenon where fine particles in non-cohesive soil are carried away or flushed out through the pores of a large particle skeleton under seepage, forming channels that lead to concentrated water inflow. This phenomenon is also known as seepage erosion. During flood control in dams, when the water level rises, the inflow carries more sand and soil, increasing the water volume. Channels caused by piping are easily formed on the outer side of dams and other hydraulic facilities. The occurrence of piping causes the soil at the bottom of the dam to be continuously discharged outward under the action of seepage force. After a long period of time, this will damage the soil skeleton of the dam foundation, enlarge the channels, and hollow out the foundation soil, causing the dam to collapse and resulting in dangerous situations such as dike breaches and dam failures. In order to promptly respond to and manage piping, it is necessary to use piping control devices in hydraulic facilities. By setting up a filter layer, reverse filtration and seepage are carried away and the seepage pressure is reduced. Ecological and dynamic balance is used to stop the sand carried by the inflow, prevent fine particles from being carried away by the water flow, and reduce and slow down the expansion of the piping holes.

[0003] However, in actual installation and use, the installation height of the piping diversion device in water conservancy facilities is mostly fixed, resulting in a limited thickness of the filter material inside the device. When the piping pressure is high, the reverse filtration and diversion effect on the piping is limited, which is insufficient. There is no measure to adjust the length of the diversion device.

[0004] Now, a new type of piping drainage device for water conservancy facilities is proposed to address the above-mentioned shortcomings. Utility Model Content
