An auxiliary construction apparatus of sidewalk blocks and a construction method for sidewalk blocks using the auxiliary construction apparatus are provided to install sidewalk blocks exactly and quickly, to construct sidewalk blocks eco-friendlily by permeating rainwater to the ground easily, to construct lawn or other raised blocks for as well as general blocks and to reduce labor cost by improving workability. The auxiliary construction apparatus of sidewalk blocks contains a base plate(21) where a hexahedral sidewalk block(10) is seated, many drain holes(23) formed on the base plate, coupling grooves(25) formed on adjacent two sides of the base plate, coupling projections(27) formed on the other two sides of the base plate, two outer walls(29) formed on the two sides where the coupling projections are formed, and many fixing pins(22) formed on the lower part of the base plate. The construction method for sidewalk blocks using the auxiliary construction apparatus comprises the steps of forming a primary lower rubble stable layer by paving rubble having the particle size of 40~50 mm to a thickness of 20~30 cm, forming a secondary middle rubble stable layer by paving rubble having the particle size of 15~15 mm to a thickness of 10~15 cm on the primary lower rubble stable layer, forming a third mat layer by spreading a mat having a thickness of 1~2 cm on the secondary lower rubble stable layer, forming a fourth sand layer by spreading a sand layer having the particle size of 3~5 mm to a thickness of 8~12 cm on the third mat layer, connecting and placing various shaped sidewalk block auxiliary construction apparatus on the fourth sidewalk block, setting various shaped or colored sidewalk blocks on each auxiliary construction apparatus and filling up the gap between the sidewalk block and the sidewalk block with rubble or sand having the small particle size. |
