Description

Technical Field

[0002] Drainage wells are mostly used in foundations with relatively deep surface weak permeable layers and lower strong permeable layers, and in foundations with many lenses and strong water-bearing zones. Since the embankment foundations of most projects are multi-layer foundations with complex geological conditions, drainage wells are widely used in the application of drainage measures. The principle of drainage is to guide the seepage water flow from the upstream of the dam into the drainage pressure relief well through the filter pipe, and prevent the seepage water flow from flowing downstream, so as to quickly reduce the pressure head, protect the stability of the dam and reduce the downstream groundwater level.

[0003] However, after being used for a period of time, the existing drainage wells are prone to accumulate a lot of debris at the bottom of the well, requiring cleaning personnel to go down the well to clean it, which is labor-intensive and easily affects the personal safety of the cleaners, and is prone to clogging the drainage well. Therefore, most existing drainage wells use a crane to lift and clean the filter screen plate inside the drainage well. For example, a new type of urban rainwater drainage well disclosed in the Chinese patent authorization announcement number: CN 210013308 U has a lifting ring on the cleaning plate, which plays the role of pulling the first steel cable, the connecting ring and the second steel cable to pull the cleaning plate upward, so that the cleaning plate pulls up the debris inside the drainage well body, which is conducive to cleaning the debris inside the drainage well body.
