摘要： PURPOSE:To supply ground water and to lower the temperature of the area by boring a large number of water permeable through holes and water holding non-through holes in a block of a material provided with specific water hold capacity, and laying it on the ground surface. CONSTITUTION:A block 1 is constituted of a brick-like substance provided with physical water-absorbing efficiency, such as a capillary phenomenon, and chemical hydrophilic efficiency and 5 - 15% of water-hold capacity. After that, water permeable through-holes 2 through which water on the ground surface permeates a lower layer and non-through water-holding holes 3 to keep the water thereon into the holes are bored in the block 1 so that they are arranged mutually in a plurality of rows at certain intervals lengthwise and crosswise. Boring is made in a state to incline to the extent of 245 - 60 against the ground surface. Then, the block 1 is laid on the ground surface. According to the constitution, the permeation capacity of rainwater, etc. is increased through the water permeable through-holes 2 and, at the same time, the water storage capacity of the non-through water holding holes 3 is increased, and the temperature of the area where the block 1 is laid on the ground surface can be lowered by water-holding latent heat of vaporization.
