<p><P>PROBLEM TO BE SOLVED: To provide a ground greening structure of a buried cleaning part capable of satisfactorily retaining the efficiency of deodorization with a simple constitution, moreover, greening the surface part of a deodorization zone and, at the same time, utilizing the greened part for other purposes too. <P>SOLUTION: This ground greening structure of buried cleaning part comprises a cleaning part 12 which is buried under ground 100 and contains a gravel layer 10 for making malodorous gas rise and pass therethrough, an air permeable sheet 14 with which the upper surface of the gravel layer is covered and a microorganism deodorization part 16 which is arranged on the upper surface side of the air permeable sheet. Further, the microorganism deodorization part 16 comprises a support base material 26 supported by a cleaning part structural material 18 so as to form a large void part 26A and a porous rigid structural body 30 which has a vertical through-hole 28, stores microorganism growth soil 32 in the vertical through-hole 28 and retains the microorganism growth soil 32 so as to prevent the soil from being compressed from the upper surface side. By making greening plants 34 vegetate on the surface layer side of the vertical through-hole 28 of the porous rigid structural body 30, the deodorization of malodorous gas, the greening, and the ground surface multi-purpose utilization are realized. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
