Abstract

PURPOSE:To tighten reclaiming control and to efficiently perform reclamation by carrying out a landfill of various dusts which are stored in a storage area by time sharing processing corresponding to the amount and disposal way of various dusts. CONSTITUTION:Various dusts are classified into usual dust, earth and sand, coarse matter, incineration ash or the like. For example, a reclaimed land 3 is divided into three areas 3A, 3B, 3C and, first dusts of kinds predetermined from the various dusts temporarily stored in a dust storage area 9 are disposed to the reclaimed area 3A in order in predetermined amounts and, subsequently, the dusts are pressed from above, for example, by a bulldozer to uniformize dust pressure and covered with soil. Further, drain treatment is applied to the surface of soil. The dusts of kinds predetermined in the same way as mentioned above are disposed to the reclaimed area 3B in order in predetermined amounts during the pressing and soil covering treatment of the reclaimed area 3A. The reclaimed area 3C is for the next disposal of dusts.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a method for disposing of waste in a landfill.

(Conventional technology) Conventionally, garbage disposal companies would transport garbage regardless of its quality to a pre-designated landfill site by truck, dump it without any planning, and then compact the garbage with a bulldozer or the like. was doing the following.

(Problems to be Solved by the Invention) By the way, in the conventional garbage landfill method described above, various types of garbage are not disposed of uniformly, resulting in unstable ground and a portion of the garbage layer that is later discarded. There was a risk that the area would sink unevenly.

In addition, since various types of garbage were thrown away without permission, subsequent work was difficult and there was a risk of accidents occurring. Furthermore, the current situation is that there is no plan in place for the order of work in garbage landfills, and the area is chaotic and unmanaged.

The purpose of this invention is to improve the above-mentioned problems by time-sharing the type and amount of garbage according to the quality of the garbage and determining the order of work for reclamation, thereby stabilizing the ground and preventing uneven settlement. An object of the present invention is to provide a method for disposing of waste at a landfill site, which prevents waste from occurring, strengthens landfill management, and efficiently disposes of waste.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention temporarily stores various types of garbage in a garbage storage area provided beside a landfill site according to the quality of the garbage. The method is characterized in that the various types of garbage stored in the garbage storage area are stored in the landfill and are disposed of in a time-sharing manner according to the size of the landfill, the amount of various types of garbage determined in advance, and the method of disposing of the garbage. This is a method of disposing of waste at a landfill site.

Further, the present invention provides a method for disposing of waste at a landfill site, in which time-sharing processing is performed as a step of disposing of waste.

It is desirable to perform the compaction process, soil covering process, and drainage process in this order.

Furthermore, in the method for reclaiming waste at a landfill, the present invention divides the land into at least three parts, and divides the land into at least three parts, a place for efficiently disposing of various types of waste, a place for compaction/covering, and a place for the next landfill. It is desirable to separate the waste into landfills.

(Function) By adopting the garbage landfilling method at a landfill site of this invention, various types of garbage are transported by truck etc. and are temporarily stored in a garbage storage area set up beside the landfill site depending on the quality of the garbage. stored. Various types of garbage are stored in this storage area according to their quality, and various types of garbage are sent to the landfill for time-sharing processing depending on the size of the landfill, the predetermined amount of each type of garbage, and the method of disposing of the garbage. A certain percentage of waste is landfilled.

As a result, the ground of the garbage layer buried in the landfill is stabilized, so that uneven subsidence will not occur later. Since various kinds of garbage are disposed of in a predetermined amount in sequence through time-sharing processing, subsequent work management becomes easier and there is no risk of accidents occurring. Furthermore, all types of garbage are disposed of in a planned manner.

In addition, by performing the garbage disposal process, compaction process, soil covering process, and drainage process in order, various types of garbage, soil covering, and water treatment can be collected within a specified time and managed efficiently. Furthermore, the landfill site is divided into at least three parts, and the work of disposing of garbage, compaction, and covering with soil can be managed efficiently and without wasting time.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

Referring to Figure 1, there is a gate 5 to enter the landfill 3 on the side of the road 1, and garbage transporters who have transported various types of garbage, soil cover, etc. by truck enter the road 1. Pass through gate 5 and enter management room 7 for reception. In the control room 7, the type and amount of garbage, for example, are reported by the garbage transporter, and based on the report, the information is input into, for example, a computer.

For example, the computer installed in the management room 7
Since a plan has been made in advance as to which type of garbage should be thrown away, the various types of garbage carried by the garbage transporter are placed in the garbage storage area 9 set up next to the landfill site 3 according to the quality of the garbage. is temporarily stored. Moreover, various types of garbage are sorted and stored in this garbage storage area 9.

Various types of garbage include ordinary garbage, earth and sand, and bulky items.

It is classified to refer to incineration ash, etc.

The landfill site 3 is divided into three parts, for example, 3A, 3B, and 3C. First, the types and amounts of garbage are sequentially determined in advance from among various types of garbage temporarily stored in the garbage storage area 9 to the landfill site 3A. dispose of. Next, the garbage is compacted from above using a bulldozer, for example, to equalize the pressure of the garbage, and a covering soil is laid down. Furthermore, drainage treatment will be performed on the surface of the covered soil.

While compaction and soil covering are being carried out at the landfill site 3A, predetermined types and amounts of garbage are sequentially disposed of at the landfill site 3B in the same way as described above. Landfill 3C is the next landfill where garbage will be disposed of.

In this way, if the landfill site 3 is divided into three parts, for example 3A, 3B, and 3C, and the process of discarding garbage and the compaction/soil covering process can be performed alternately, the landfill can be efficiently carried out. .

The size of the landfill site 3 must be determined in advance, as well as the type of garbage.

By reliably obtaining the amount of waste and temporarily storing it in the waste storage area 9, the work of disposing of the waste in the landfill 3 can be carried out in a time-sharing manner. What's more, because specific waste is not collected in one place and thrown away, it is evenly distributed, which stabilizes the ground and prevents uneven subsidence later on.

By making a plan in advance, such as the order in which garbage should be disposed of, based on the size of the landfill site 3, the type and amount of garbage, and carrying out the work according to that plan, efficient landfilling can be carried out. Landfill management will be better.

In addition, in certain landfills, it is possible to quickly develop the area by filling in sections with only the same type of waste, and with regard to waste containing toxic substances, chemicals can be added to cause a reaction and treated to ensure that there are no problems before being sent to the landfill. It is also possible to

Note that this invention is not limited to the embodiments described above, and can be implemented in other forms by making appropriate changes.

[Effects of the Invention] As can be understood from the description of the embodiments described above, according to the present invention, various types of garbage are transported by trucks, etc., and the garbage is stored in a garbage storage area set up beside a landfill. Temporarily stored depending on the situation. The various types of garbage stored in this storage area depending on the type of garbage can be processed in time-sharing manner, depending on the size of the landfill, the predetermined amount of each type of garbage, and the method of disposing of the garbage. A certain percentage can be landfilled.

As a result, the ground of the garbage layer buried in the landfill is stabilized,
Unequal subsidence will not occur later.

Since various types of garbage are disposed of in a predetermined amount in order through time-sharing processing, subsequent work management becomes easier.
Accidents will no longer occur. Moreover, various types of garbage can be systematically processed and landfill management can be easily performed.

Further, by sequentially performing the garbage disposal process, compaction process, soil covering process, and drainage process, various types of garbage, soil covering, and water treatment can be efficiently managed as long as they are completed within a specified time. Furthermore, by dividing the landfill site into at least three parts, the work of disposing of garbage, compaction, and covering with soil can be managed efficiently and without wasting time.
