The present invention relates to a block structure which is used for sidewalks, roadways, and river slopes. Provided is a block structure capable of being equipped with both a filler block and a vegetation material, which includes the following parts: a main body block where multiple fixed blocks are arranged and fixed at the inside, vertically punctured insertion holes are formed among the fixed blocks, semicircle connection holes are formed on the exterior at regular intervals, and a ground-touching part is formed to be extended a little bit between the connection holes； a filler block which is inserted into the insertion holes and the connection holes, and performs the function of a block along with the main body block and the fixed blocks； and a vegetation material which is put into the insertion holes and the connection holes, and where a plant grows. The ground-touching part is interconnected with a ground-touching part of another main body block, which is desired to be connected, and enables the semicircle connection holes to make a circle, and the filler block and the vegetation material are selectively formed at the insertion holes and connection holes of the main body block. Therefore, convenience of use is improved by enabling the filler block and the vegetation material to be selectively formed at the insertion holes and connection holes of the main body block； the filler block is inserted into the main body block and stably performs the function of a block； and an eco-friendly design is realized by enabling the vegetation material to be formed at the main body block.본 발명은 인도, 차량용도로, 하천법면에 사용되는 블럭의 구조에 관한 것으로서, 내부로 다수의 고정블럭이 고정배열되고, 고정블럭 사이로 상, 하가 관통되어 이루어지는 인입공이 형성되고, 외측으로 반원형태의 연결공이 간격을 두고 형성됨과 동시에 상기 연결공 사이에 일부 연장되는 접지부가 형성되는 본체블럭； 상기 인입공과 연결공에 인입되어 본체블럭, 고정블럭과 더불어 블럭의 기능을 수행하는 채움블럭； 및 상기 인입공과 연결공에 채움되어 식물이 식생되는 식생재；가 포함되어 구성되어, 상기 접지부가 연결하고자 하는 다른 본체블럭과 상호 접지되어 반원형태의 연결공이 원형을 이루도록 연결되며, 상기 채움블럭과 식생재가 본체블럭의 인입공과 연결공에 선택적으로 형성됨을 특징으로 하는 채움블럭 및 식생재가 겸용으
