RESERVING AND PENETRATING CONSTRUCTING METHOD IN GROUND BY HONEYCOMB PLATE

PURPOSE:To temporarily reserve draining water and prevent the flood of draining quantity by providing drainage side-gutters provided with catch basins in proper positions along both sides of a subgrade, and laying a honeycomb plate in the ground between them. CONSTITUTION:A drainage side-gutters 3 are provided along both sides of a subgrade 1, and catch basins 4 are disposed in proper positions in the course. The catch basins 4 are mutually connected through a penetrating trench 5 charged with crushed stones. Under the penetrating trench 5, a honeycomb plate 6 is laid. The honeycomb plate 6 is formed of a honeycomb structure 6a and a permeable sheet 6b. Draining water such as rainwater is temporarily reserved in the ground, whereby the draining quantity can be suppressed to prevent disasters such as flood.
