Abstract

Since 1960, Korea the town center was developed intensively due to rapid industrial development. As a result of the development, the population was concentrated in urban areas and the green area was decreased. Due to the decrease of the green area, the circulation system of the rainwater was changed, hence the rainwater was not introduced into the groundwater., On the other hand, the water on the surface of the road was changed into the water for flowing to the river and evaporation. The changes in the water flow cause many problems, and the depletion of the groundwater does not create an environment in which microorganisms and plants can live. in Korea, permeable pavement construction is increased to solve these problems, but existing pavement blocks have many problems. The pores of the permeable block are clogged due to the accumulation of dust or whitening phenomenon, and the permeability is lost. In this study, the solution of the problems of existing permeable block were suggested by using polymer and artificial permeable pipe, and strength, permeability and service life are increased, The relationship between the substitution rate of the polymer and the mixing ratio of the artificial permeable pipe was analyzed.

인공투수관을 혼입한 폴리머 투수블록은 폴리머를 치환할 경우 강도, 공극률, 투수계수 등의 'KS F 4419'(보차도용 콘크리트 인터록킹 블록)의 기준보다 높은 결과 값이 측정되었으며, 제품의 경량화가 가능할 것으로 판단된다. 폴리머 재료의 단가 문제로 인해 경제성을 고려하여 시멘트와의 치환율을 14%로 선정하는 것이 효과적이라고 판단된다. 또한, 인공투수관의 혼입율의 3가지 수준 중 2.0%가 가장 적당하다고 판단되며, 3가지 수준에 대한 측정 값이 큰 차이를 보이지 않는 것으로 나타났다. 공극률과 투수계수의 경우 2%에서 개선된 값이 측정되었기 때문에 인공투수관 혼입율 2%의가 효과적일 것으로 판단된다. 투수블록 제품화를 하기 위해선 경제성을 고려해야 하며, 본 연구에서 사용된 폴리머 VAE 경제성이 떨어지기 때문에 다른 폴리머의 재료와 비교 실험을 진행하여 문제점을 개선 한다면 투수블록 제품화가 가능할 것이라 판단된다. 본 연구의 결과는 추후 폴리머 및 인공투수관을 활용한 연구의 기초적인 자료로 사용 가능 할 경우 효율적인 데이터로 활용이 가능할 것으로 판단된다.
