摘要： PROBLEM TO BE SOLVED: To obtain an impervious sheet capable of feeding water supplied by rain or various sprinkling means to a greening materials on impervious sheet simply and surely even if its installing position is a steep slope surface by forming specific blocking weirs on its surface in a prescribed arranging pattern. SOLUTION: This impervious sheet 11 installed at a slope surface such as a waste material disposing place, slope surface of a landfill, roof top of a structure, etc., is obtained by forming water blocking weirs 1b capable of damming up and storing the water flowing down over the impervious sheet 11 by a prescribed amount on the surface of the impervious sheet 11 in a prescribed arranging pattern. In this case, the impervious weirs 1b are preferably formed as one unit with the impervious sheet 11. Also, it is possible to install these impervious sheets 11 on the slope surface as an installing object, arrange a water- holding agent capable of planting in a surrounded space in at least these impervious weirs 1b on the surface of the laid impervious sheet 11 and provide plantings such as plant seeds or saplings for greening the slope.

摘要： PURPOSE:To provide a water barrier sheet used in a waste disposal yard capable of easily preventing the leakage of sewage from a destructed place even when the sheet is damaged. CONSTITUTION:For example, a water barrier sheet is constituted of a lower water barrier sheet 12 composed of a sheet member formed from a soft synthetic resin or rubber, an upper water barrier sheet 13 composed of the same member as the lower water barrier sheet 12 and forming planar hermetically closed space along with the lower water barrier sheet 12 and the water swellable nonwoven fabric 14 arranged to the planar hermetically closed space 15. When sewage is leaked by the damage of the water barrier sheet 11, the water swellable nonwoven fabric 14 absorbs sewage to be swollen and the upper and lower water barrier sheets 13, 12 are brought to a close contact state to prevent the passage of sewage and the leakage of sewage.

摘要： PURPOSE:To provide a defective point detection method for the joint part of a water-barrier sheet, which allows easy and prompt detection work an the spot and specifies a defective point with precision. CONSTITUTION:In the direction of extension of a joint part 13, the joint part 13 is covered for a specified range, and while a flexible permeability member 15 is rolled in, an air-tight adhesive tape 14 is banded on the upper surface of a water-barrier sheet 11, so that an air space 16 is formed at the end face of the joint part 13. Further, while bath ends of the air space 16 are sealed up with sealing-up seals, a pressure-proof hose is inserted into one end, and air is sucked with a vacuum pump, so that the air space 16 comes into negative- pressure state. Then, while the negative-pressure state is left alone far a while, changes in pressure is observed, and by detecting drop in the negative-pressure, presence of defective points is detected.

摘要： PROBLEM TO BE SOLVED: To provide a roof structure capable of enhancing energy efficiency for snow melting work in winter and preventing an increase in internal temperature in summer. SOLUTION: The outer and inner side parts of a roof material 3 are covered with roof membranes 4 and 5, for which, for example, a sealing sheet is substituted, for the purpose of constructing a building for allowing the upper section of a disposal site 1 to be fully sheltered from outside. Warm air is uniformly distributed and sent to the respective parts of a garret space through a blast duct 6 wherethrough the warm air is issued into the space. Plural suction holes 8 are opened on the top part of a roof, and the warm air blown into the in-ceiling space can be discharged outside through a suction pipe 9 connected to the suction holes 8. The air pressure of the warm air is set equal to or slightly lower than atmospheric pressure because the roof membranes 4 and 5 are expanded when blast quantity is larger than suction quantity.

摘要： PROBLEM TO BE SOLVED: To repair water leakage points easily by forming a filling space partitioned with a partitioning member between a water impervious sheet and a sand protective sheet, detecting a leak current by electric detecting terminals on the impervious sheet so as to specify the leakage points, and filling the specified filling space with an impregnant for repair and solidifying it. SOLUTION: The horizontal electric field distribution in a waste treatment site 10 that is measured by electrodes 17 provided on a water impervious sheet 12 and the resistivity measured in advance are used to specify the water leakage points. After the points are specified, a block partitioned with a mat-like unwoven cloth 15 is filled with an impregnant for repair and solidified thereafter. Namely, an injection pipe 20 is installed toward the filling space held by a net resin mat 16 in a block including water leakage position, at such a position that it is brought into contact with a sand protective sheet 18, and an impregnant is injected and solidified. When the impervious sheet 12 is laid with a laying structure 14, the pipe 20 is arranged in advance on the bottom and slope of the site 10 in a manner that it may communicates with the filling spaces of respective blocks. Thus, the water barrier sheet can be repaired without removing the waste 11.
