PURPOSE: A trench cover is provided to ensure excellent structural rigidity and easy installation in various field conditions and to minimize noises caused by friction or impacts. CONSTITUTION: A trench cover(100) is configured as follows. Supporting parts(120) are integrally formed on the right and left ends of a horizontal portion. A plurality of vertical portions are projected on the top of the horizontal portion between the supporting parts. A buffer material(150) is coupled to coupling grooves, which are formed to open on side and bottom surfaces of the supporting parts, in order to reduce impacts and noises. Rubber pads(140) are inserted in insertion grooves formed on the top of the vertical portions and partially protrude outside to provide elasticity for noise and slip prevention. |
