PURPOSE: A water-permeable pile for pavement is provided to improve the durability of concrete and an elasticity paving material by increasing the permeability at the time of a localized torrential downpour, thereby smoothly discharging rainwater to the ground. CONSTITUTION: A water-permeable pile for pavement includes a cover (10), a pile for construction (20), a cylindrical supporting unit (30). The cover has coupling holes (11) at every corner thereof, and slots (12) so that water is flowed in. The pile includes coupling holes (21), a mesh receiving part, a drain (23), drain grooves (25), and a string receiving hole (26). The pile for construction and the cylindrical supporting unit are fixed through the string receiving hole by using a wire or a string, and are used by being tied and fixed with a string that is withdrew through an upper through hole (27) of the pile for construction. |
