The present invention relates to a grating to prevent landslide using a water permeable block and a method to manufacture the same. The present invention relates to a grating with an improved disaster reduction function capable of preventing sediment inflow and draining water easily so as to prevent occurrence of a heat island phenomenon and city flooding due to increase of impervious area in accordance with urbanization, and a method to manufacture the same. According to the grating to prevent landslide using the water permeable block according to the present invention, a porous water permeable block using waste shells is installed in an inner space of a grating structure by applying the grating structure so as to solve a blockage problem of a drain pipe due to all sorts of wastes and sediment inflow of a conventional steel grating. Thus, the sediment inflow is prevented, and water permeation and walking can be facilitated easily. Therefore, the grating apparatus can be applied to various rainfall characteristics, and maintenance costs thereof during operation also can be reduced. |
