Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems wherein residual landfilling quantity is calculated heretofore by a method for calculating volume by dividing landfilling quantity, which is calculated by measuring investigation using a measuring device due to a technical expert or measured on the basis of a weight, by a supposition unit volume weight to estimate and calculate existing landfilling quantity and a method for simply measuring already known landfilling height to form and calculating a cross section drawing but cost is required for measurement in the first method and, since a unit weight is largely different according to the kind of waste in the second method, the precision of the calculated value is bad while, in a third method, an index for measuring height can not used for a long period of time. <P>SOLUTION: In this calculation method of the residual landfilling volume, a landfilling index is installed around the landfilling disposal site, the slope distance up to a landfilling surface is measured from the index as shown by Fig. 3 to be input to calculate a cross-sectional area as shown by Fig. 4 and the residual landfilling quantity is calculated by an average cross section method. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to the calculation of the remaining landfill capacity of a waste landfill site.

  The conventional method for calculating the remaining landfill capacity of a landfill site is as shown in FIG. 1, which is a vertical cross-sectional view calculated by a survey survey calculated by the average cross-sectional method (hereinafter referred to as the first method), The amount of landfill measured by weight is divided by the assumed unit volume weight, the volume is obtained, the existing landfill volume is estimated, and the remaining landfill capacity is obtained by dividing from the whole (hereinafter referred to as the second method). In addition, there is a method (hereinafter referred to as a third method) that has already been disclosed by the present inventor, that measures the landfill height by simple measurement, creates a cross-sectional view, and calculates the average cross-sectional method.

However, according to the above technique, in the first method, when calculating the remaining landfill capacity, it is necessary to carry out surveying surveys that require specialized techniques using surveying equipment, and there is a problem in reducing surveying costs. In the second method, since the unit weight varies greatly depending on the type of waste, the accuracy of the remaining landfill capacity is poor.
In the third method, a number of indicators for measuring the height are provided on the water-impervious sheet, but the display is made with paint so that the sheet is not damaged, and it is difficult to use for a long time.
Accordingly, an object of the present invention is to calculate the remaining landfill capacity over a long period of time while maintaining necessary accuracy by simple measurement that does not require specialized technology.

  In order to solve the above problems, the invention sets a landfill index around the landfill disposal site as shown in FIG. 2, and measures and inputs the slope distance from the index to the landfill surface as shown in FIG. This is a method of calculating the value of the location shown in FIG. 4, obtaining the cross-sectional area from the value, and calculating the residual landfill capacity by the average cross-sectional method.

  According to the present invention, measurement by a specialist using a surveying instrument is not required, and a remaining landfill capacity can be calculated by a person who does not have specialized skill only by simple measurement using a distance measuring instrument. In addition, by installing the landfill index outside the disposal site, it is possible to use piles and dredging as the index, and the index can be used for a long time. In addition, the distance from the index is directly input and converted in this system, thereby improving the ease of work.

One embodiment of the present invention is shown in FIG. 2, FIG. 3, FIG. 4, and FIG.
An installation example of the measurement index in the method of the present invention is shown in FIG. A measuring method using this index is shown in FIG. FIG. 4 shows the locations calculated by inputting the measured values. FIG. 5 shows an input / calculation result using the spreadsheet software.

"Effect of the embodiment"
According to this embodiment, without performing survey survey using surveying equipment by a specialist, rather than the remaining landfill capacity calculated by converting from the carry-in weight by simple measurement performed by the disposal facility managers themselves, It is possible to calculate the remaining landfill capacity with high accuracy, and it is possible to create materials useful for the maintenance of the landfill site at low cost.

"Other embodiments"
In the embodiment of FIG. 3, the measurement is performed by installing an index at both ends of the landfill disposal site, but it may be obtained by setting an intermediate point in the landfill disposal site and subdividing the area of A3 in FIG. 4. .

It is sectional drawing by a prior art. It is an installation figure of a landfill index showing one embodiment of this invention. It is a method figure of the simple measurement which shows one Embodiment of this invention. It is sectional area calculation explanatory drawing which shows one Embodiment of this invention. It is the calculated value of the remaining landfill capacity which shows one Embodiment of this invention.
