A TRENCH STRUCTURE WITH FOLDABLE FUNCTIONAL COVER

摘要

PURPOSE: A trench structure with a foldable cover is provided to reduce work time and costs by simplifying the coupling and decoupling work of a trench when the trench is cleaned. CONSTITUTION: A trench structure with a foldable cover comprises a trench(100) and one or more trench covers(200). The trench has a drainage way(110) and cover support protrusions(120). A portion of the drainage way is buried in the ground. The cover support protrusions are integrally formed on both sides of the top of the drainage way. The trench covers are installed in the cover support protrusions and have multiple recessed inlets(210).
