| titleOfInvention | Concrete drain structure having l-type drain hole |
| abstract | The concrete drainage structure of the present invention, which is buried in the ground (1) and has one upper portion positioned at the other edge of the sidewalk portion 20, includes a concrete body portion 100; A boundary stone 200 coupled to the upper end of one side of the main body 100; including, a side drain hole 200h formed on the other side of the boundary stone 200 and a main body portion drain hole formed on an upper surface of one side of the main body 100 (100h) provided with an L-type grating (300, grating) fitted to the L-type drain hole (h) so as to cover the L-type drain hole (h) and the L-type drain hole (h) formed by interconnecting, the The boundary stone 200 is 68 to 81 wt% of fine powder pulverized to a size of 0.6 to 1 mm by recycling waste tires; 15-28 wt% of liquid urethane binder; It is a boundary stone of a rubber material containing; 2.2 to 5% by weight of a flame retardant. The present invention is characterized in that it prevents flooding of the road and can drain it quickly because it drains the rainwater generated by the torrential rain to the lower surface and the side at the same time using the L-shaped drain hole. The boundary stone applied to the present invention is a recycled waste tire that is treated as waste, and the waste tire goes through the bead wire removal step, the first crushing step, the second crushing step, and the 3rd to 4th crushing step to determine the average particle; It is produced as fine powder of waste tires through a centrifugal force dust collection step and a steel separation and screening step to remove internal iron. |
