The present invention is to provide a trench cover which is simply and easily installed, while a mobility and occurrence of noise caused by a friction and an impact are minimized, and a function of a speed bump can be effectively performed. Disclosed is the trench cover comprising: a body formed as a square or a right-angled triangle of which one side is hypotenuse when viewed on a plane, in which a plurality of drainage holes are formed on an inner side of a border; support legs formed projecting downwards, respectively, in apex areas, when viewed on a plane, in a bottom border of the body; connection holes of which bases are horizontally formed, respectively, parallel to the side on a vertical side and a hypotenuse, when viewed on a plane, in the side of the body; and connection hooks having a shape of being connected and coupled by corresponding to the connection holes, of which bases are horizontally formed parallel to the side on the vertical side and the hypotenuse, when viewed on a plane, in the side of the body, in which a hypotenuse side and a vertical side of the body are connected in a point symmetry, respectively, to a hypotenuse side and a vertical side of a body of another trench cover. |
