Manufacturing method of environmentally friendly spheric Porous Concrete Cobble
The present invention relates to a method for manufacturing an environmentally friendly spheric porous concrete block (PCB), more particularly, in which the spheric PCB has a porosity of 21% or more and is excellent in permeability and durability. In addition to purification of the water quality of river polluted by sewage, the ecosystem can be preserved and restored due to vegetation. During a heavy rain period with tractive force over 45, the loss of soil and the collapse of the normal surface caused by clavicle can be prevented. The compressive strength of the PCB is 250 kgf/cm^2 and the concrete strength is maintained, so that the service life reaches 70 years, and in a case of installation in a river, the economic feasibility will be maintained even after the service life. Moreover, adsorption and removal of heavy metal contaminants such as lead, cadmium, zinc and the like in nonpoint-contaminated areas allow for purification work, a habitat for fish and shellfish in the water is provided to remove CO_2 in the water and red tide is prevented due to oxygen generation to restore ecosystem in the water.
본 발명은 친환경 다공성 구형체 자갈 블럭(Porous Concrete Block, PCB) 제조방법으로서, 더욱 상세하게는 구 형태의 PCB는 공극율 21% 이상으로 투수성과 투기성이 우수하고 오수에 의해 오염된 하천의 수질 정화 뿐만 아니라, 식생으로 인한 생태계의 보존과 복원을 할 수 있으며, 소류력이 45 이상으로 집중호우시 쇄골현상으로 인한 토사유실과 법면 붕괴를 막을 수 있고, 압축강도가 250kgf/㎠으로서 콘크리트 강도를 유지하여 사용 수명이 70년에 이르며, 하천에 설치시 사용수명 후에도 수질정화가 지속되어 산업폐기물 생성이 되지 않는 경제성이 보장될 뿐만 아니라 비점오염지역의 납, 카드뮴, 아연 등의 중금속 오염물질의 흡착 및 제거로 정화작업이 가능하고 수중의 어패류의 서식공간을 제공하여 수중의 CO2를 제거하고 산소발생으로 적조현상을 방지하는 등 수중생태계 복원이 가능한 특징이 있다.
