이어서 상기 주형틀(4)을 해체하고 용탕이 응고된 미끄럼 방지 가로수보호덮개를 얻을 수 있었다(S70).Subsequently, the mold 4 was dismantled to obtain a non-slip roadside protective cover in which molten metal was solidified (S70).

상기와 같은 제조방법에 의하여 제조된 가로수보호덮개는 표면에 미끄럼 방지 요철이 형성되어 표면에 마찰력을 증가시켜 우천시와 결빙시 등에 보행자의 미끄럼을 방지하여 이로 인한 안전사고 등을 예방할 수 있는 것이다.
상기와 같은 제조방법에 의하여 제조된 가로수보호덮개는 분활 제작되는 것으로 가로수 하단의 둘레부분에 가로수보호덮개 받침틀을 설치하고 받침틀 위에 가로수보호덮개를 조립설치하여 가로수 하부의 흙에 공기나 물이 스며들게 하는 것이다.The roadside protective cover manufactured by the manufacturing method as described above is to prevent the slippery irregularities are formed on the surface to increase the frictional force on the surface to prevent the pedestrian's sliding in rainy weather and freezing, thereby preventing safety accidents.
The roadside protection cover manufactured by the manufacturing method as described above is manufactured by splitting the installation of the roadside protection cover support frame at the periphery of the bottom of the roadside and assembling and installing the roadside protection cover on the support frame so that air or water is infiltrated into the soil at the bottom of the roadside tree. will be.

이상에서는 본 발명의 바람직한 실시예에 대하여 도시하고 또한 설명하였으나, 본 발명은 상기한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 본 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 기재된 청구범위 내에 있게 된다.
