AI Technical Summary
Existing curb stones are prone to clogging after prolonged use, making it difficult to drain water effectively and in a timely manner, posing a safety hazard, especially during heavy rain.
A drainage structure for curb stones in greening roads is adopted, including a main frame, a primary filter element and a secondary filter element. The dual filtration system of the primary and secondary filter elements is detachably installed on the main frame and respectively set in the first installation space and the second installation space. The filter pore size gradually decreases to intercept debris.
It effectively prevents drainage channels from becoming clogged, has a simple structure, is easy to disassemble and maintain, and can effectively filter out most debris, reducing the risk of clogging and ensuring smooth drainage of rainwater.
