NON FLAMMABLE RESIN RETAINING WALL BLOCK AND CONSTRUCTION METHOD FOR VEGETATION RETAINING WALL USING THAT

The present invention comprises: a block main body including an inclined surface provided on a front surface thereof and an accommodation space provided at the rear; an accommodation groove portion provided on the inclined surface and providing a vegetation space where plants grow; and a barrier provided in the block main body to divide the accommodation space into the accommodation groove portion and a retaining groove portion. The block main body is manufactured by using a sheet type complex molding material formed with 5-25 parts by weight of a flame retardant agent with respect to 100 parts by weight of a mixture composed of a thermosetting resin composition and glass-reinforced fibers. The flame retardant agent is made of one or at least two substances from a group consisting of hydrate-based, halogen-based, antimony-based, nitrogen-based, and phosphorus-based substances. According to the present invention, a flame-retardant synthetic resin retaining wall block is capable of providing a vegetation environment where plants can grow. 본 발명은, 전면에 경사면을 구비하고, 후방부에 수납공간이 구비되는 블록본체; 상기 경사면에 구비되고, 식물이 자라는 식생공간을 제공하는 수납홈부; 및 상기 수납공간을 구획하여 수납홈부 및 유지홀부로 구분하도록 상기 블록본체에 구비되는 격벽을 포함하고, 상기 블록본체는, 열경화성 수지 조성물 및 유리강화섬유로 이루어지는 혼합물 100중량부에 대하여 난연제 5~25중량부로 이루어지는 시트 형태의 복합성형재료를 사용하여 제조되고, 상기 난연제는 수화물계, 할로겐계, 안티몬계, 질소계, 인계로 이루어진 그룹에서 하나 또는 둘 이상으로 이루어는 것을 특징으로 한다.
