<p>PROBLEM TO BE SOLVED: To provide a method for removing rain water in a waste disposal site in which rain water is rapidly flowed down toward drainage facilities by easily and forcedly draining rain water retained on a seepage control sheet. SOLUTION: In the method for removing rain water in a waste disposal site, the waste disposal site is divided into a plurality of sections 20. While the landfill layer of waste 13 in a part of the sections 20 is covered with a seepage control sheet 14 and landfill work of waste 13 is continued in the other section 20', landfill of waste 13 is performed. A drainage channel 30 is provided around the sections 20 covered with the seepage control sheet 14. Also, in the case of covering the landfill layer, air bags 31 are interposed between the upper face of the landfill layer and the seepage control sheet 14. When rain water deposits on the upper face of the laid seepage control sheet 14, air is supplied into the air bags 31 to expand them. Rain water is flowed into the drainage channel 30 and drained by raising the seepage control sheet 14.</p> |
