Description

Technical Field

[0001] This application relates to the field of water conservancy engineering technology, such as a seepage prevention device at the bottom of a sluice gate. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] In sluice gate engineering, waterstops are key components for preventing seepage, typically installed on the sides and bottom of the sluice gate to ensure its sealing and seepage prevention performance. However, due to differences in installation location and operating environment, waterstops face varying friction and stress conditions during actual operation. The bottom waterstop, in particular, directly bears the scouring of water flow and the abrasion of silt, resulting in a harsher working environment and a significantly shorter service life compared to the side waterstops. When seepage occurs in the bottom waterstop, current technology usually requires replacing all waterstops in the sluice gate simultaneously, rather than replacing the bottom waterstop separately. This practice not only increases maintenance costs but also leads to premature replacement of the side waterstops before they reach their service life, resulting in resource waste. Therefore, extending the service life of the bottom waterstop and reducing its replacement frequency has become an urgent technical problem to be solved in the field of sluice gate engineering.
