【発明の属する技術分野】
本発明は、廃棄物処分場の内面に、石灰系の固化剤を混入した泥を塗着して不透水層を形成し、廃棄物は全て処分の度に石灰系の薬剤で安定化してから投入し、重機等により踏み固めて汚水が地下に浸透しない不透水層とし、この作業を繰り返してグランドレベル迄埋立て、その上部を改質・安定化した廃棄物を利用した盛土により埋立てた廃棄物処分場の埋立作業に必要な空間を確保して埋立地である廃棄物処分場を覆う屋根設備に関するものである。
【0002】
【従来の技術】
従来は、廃棄物処分場を被覆する施設である建築構造物として、地上に突出する形状となるため、周辺環境との調和を図るように配慮したもので、固定式として常時外界と遮断するテント式のアーチ、トラス、ラーメン、スペースフレーム、シェル、サスペンション、ハイブリッド等の設備と、これらを開閉式として必要に応じて降雨および日射の侵入、大気の移動を許して環境を制御する方式とかがあるが、その一例として、廃棄物を投棄する埋立てピットの両側に、隣接する組立ヤードに跨る区間に亘り走行レールを敷設したならば、前記組立ヤードにおいて走行レール上に収縮状態で蛇腹式テント屋根構造物を組み立てるとともに、該蛇腹式テント屋根構造物の内部にフレームを利用して被覆用遮水シートを取付け、次いで前記蛇腹式テント屋根構造物を前記走行レール方向に伸長させると同時に、前記被覆用遮水シートを展張し、前記埋立てピットを覆う屋根体を構築する屋根設備の構築工程と、前記埋立てピット内に廃棄物を投棄し埋め立てを行う埋立て処理工程と、埋立てピット内に廃棄物の投棄を終えたならば、前記被覆用遮水シートを蛇腹式テント屋根構造物から切り離し、埋立て領域を被覆する遮水シートを敷設する被覆処理工程と、前記蛇腹式テント屋根構造物を収縮し撤去するとともに、前記被覆用遮水シートの上面に覆土を行う埋立て最終処理工程と、からなることを特徴とする埋立て処理方法(例えば、特許文献1参照)が存在している。
また、被覆施設の設置方法として、埋立地全体を一つの構造物で覆うタイプと、埋立地を分割して一部の区画のみ覆い、埋立の進行に合わせて被覆施設を順次移設・移動していくタイプとがある。

【発明が解決しようとする課題】
従来の廃棄物処分場における屋根設備は、蛇腹式テント屋根で、組み立ての際は、小面積の組立ヤードにより構築できる効果はあるが、埋立ピット全体を一つのテント屋根で覆うタイプの場合は、大容量の埋立地を造成できるため、スケールメリットによるイニシャルコストの低減が期待できるが建築法上の制約があり、強風、雪の重さ等に対応する必要がある。また、被覆施設の移動がないので、一定の環境管理を継続すれば安定した環境保全が図られるが、一方、換気および照明設備などの維持管理施設と環境保全施設とが大規模となり、施設の維持管理費が嵩む可能性もある。また、埋立ピットを分割して一部の区画毎に覆うタイプの場合は、埋立地を分割するための構造物が必要となるが、各埋立地が小規模となるため、被覆施設や浸出水処理設備などの建設費を軽減できる。また、埋立地として利用する範囲が制限でき、跡地利用および環境保全面で有利となる。さらに、小規模な埋立地となるため、管理が容易となる。しかし、全体として制作費が嵩むという欠点がある。
【0005】
これに対して、本発明に係る廃棄物処分場を覆う屋根設備は、本発明者が既に発明をした特許第3131684号公報で示された廃棄物処分場の内面に、石灰系の固化剤を混入した泥を塗着して乾燥固化して不透水層を形成し、廃棄物は全て廃棄の度に改質・固化施設により改質・固化してから投入し、重機等により踏み固めて汚水が地下に浸透しない不透水層とし、その上面に溜った自然の雨水を貯め、ポンプアップして廃棄物の改質・固化施設に送り、この作業を繰り返してグランドレベル迄埋立て、その上部を改質・固化廃棄物を利用した盛土により埋立てた廃棄物処分場の埋立工法によって処理される埋立てピットを覆う廃棄物処分場を覆う屋根設備のため、換気および維持管理施設とが小規模で良く、施設の制作費用および維持管理費が安価ですむものである。また、埋立ピットの設置場所によって天井高さに制限があっても全く問題がないものである。
【0006】
本発明は、このような事情に鑑み、建築法上の制約も回避でき、強風、雪の重さにも全く問題のない。しかも換気、維持管理施設は不要であったり、小規模で良かったり、制作費が低減でき、天井高さの制約という問題も解決した屋根設備を提案するものである。
【0007】
【課題を解決するための手段】
本発明は、前記課題の解決を図ったもので、次のような技術手段を採用した。請求項1記載の発明においては、廃棄物を投棄する埋立ピットを覆う屋根設備において、選択した平坦な土を掘削して埋立地を形成し、その掘削土で外周に堰堤を築き、前記埋立地中央に入口から反対側に通じる廃棄物運搬通路を確保して残りの範囲を金属パイプ、ブラケット、連結金具で足場を組むように縦横に組み立て、縦設した金属パイプの高さを略堰堤の高さにして、中央の廃棄物運搬通路の上部には、網状金属板、パンチメタル等を敷設し、残りの堰堤迄は縦設した金属パイプと堰堤間をベニヤ板等の平板を敷設し、この網状金属板、平板の上に長尺細幅シートの被覆シートを長手方向端部が重なるように並べて張り、これ等を含んだ屋根設備全体をネットカバーで覆うという技術手段を採用した。
【0008】
請求項2記載の発明においては、選択した平坦な土を掘削して埋立地を形成し、その掘削土で外周に堰堤を築き、前記埋立地中央に入口から反対側の堰堤まで通じる廃棄物運搬通路を形成し、この廃棄物運搬通路部分を除いた範囲を金属パイプ、ブラケット、連結金具で堰堤の高さと略同等の高さまで縦横に足場のように仮設組み立てし、前記中央の廃棄物運搬通路の上部に網状金属板、パンチメタル等を敷設し、残りの外周に形成した堰堤迄は、組み立てた仮設足場と堰堤間にベニヤ板等の平板を敷設し、該網状金属板、平板の上に長尺細幅シートの被覆シートを長手方向端部が重なるように並べて張り、これ等を含んだ屋根設備全体をネットカバーで覆い外周を固定するという技術手段を採用した。
【0009】
【実施例】
先ず、本発明の廃棄物処分場について簡単に説明する。
ゴミ(主にリサイクルの輪から外れた可燃ゴミの焼却灰)を資源として活用するための廃棄物処分場である。これは「最終処分場」ではなく、「セメント原料の保管施設」で、貝殻と同じ「カルシウム」を用いて国土の環境保全に努めながら、安定した循環型社会を築いていくための廃棄物処分場である。
【0010】
それは、図2に示すように埋立前の作業として、選択した平坦な土地を掘削して埋立地1(掘削地)を形成し、その掘削土で外側に堰堤2を築き、基礎地盤に石灰石3を敷いて底部と側部に不透水層4を施し、上部に遮水シート5を張る。
【0011】
次に、図3に示すように埋立中として、石灰系の薬剤で安定化した焼却灰6(図4参照)を埋め立て、埋立層の表面を防水シート7で覆い、掘削土で築いた堰堤2を崩して防水シート7の上部に覆土8を施し、さらに覆土8を保護するために法面を緑化9する。
【0012】
さらに図4に示すように埋立後の作業として、覆土8の全面を緑化10して安定化した焼却灰6を保管しながら、跡地を公園等に活用し、安定化した焼却灰6は循環型社会を築いてからセメント原料としてリサイクルするものである。
【0013】
この廃棄物処分場(ゴミを捨てない保管型処分場)は選択した土地の広さにより、図5に示すように掘削広さに合わせて周囲を土堰堤2で覆うようにし、中央に水処理施設11を設け、区画堤12で略4等分して4つの埋立区画13を形成して、順次石灰系の薬剤で安定化した焼却灰6を埋め立てて、4つの埋立区画13を埋め立てるものである。さらに、図6に示すように区画するには、その土地に合わせて種々の形状が採用できる。
【0014】
そして、黒色の部分は水処理施設、白色抜きの部分は区画された埋立区画で、(a)(b)(c)(e)(g)(h)は4区画、(d)は18区画、(f)は26区画にしたものをそれぞれ示すものである。この他区画数は適宜選択できることはいうまでもない。
【0015】
以下、本発明の一実施例を図1に基づいて詳細に説明する。
図1は、本発明の第一実施例を示し、例えば台風等、強風にさらされる地域、雪の多い地域に設置する場合に有効なものである。
一実施例としては、図1に示すような屋根設備で、選択した平坦な土を掘削して埋立地1を形成し、その掘削土で外周に堰堤2を築き、前記埋立地中央に入口から反対側に通じる廃棄物運搬通路14を確保して残りの範囲を金属パイプ15、ブラケット、連結金具で足場を組むように縦横に組み立て、縦設した金属パイプ15の高さを略堰堤2の高さにして、埋立地中央の廃棄物運搬通路14の上部には、網状金属板16、パンチメタル等を敷設し、残りの堰堤2迄は縦設した金属パイプ15と堰堤2間をベニヤ板等の平板17を敷設し、この網状金属板16、平板17の上に長尺細幅シートの被覆シート18を長手方向端部が重なるように並べて張り、これ等を含んだ屋根設備全体をネットカバー19で覆うようにした廃棄物処分場を覆う屋根設備で、沖縄県、高知県等、台風が上陸することが多い地域などに設備すると、風圧に耐える、しかも建築法の制限を受けない、廃棄物処分場を覆う屋根設備を得ることができる。
【0016】
上記のような構成を有するので、入口20(図2を参照)から、反対側の奥側に一定量の廃棄物を前記構成のように堰堤2間に張り渡したベニヤ板等の平板17と網状金属板16等の上部に長尺細幅シートの被覆シート18を並べて張った屋根設備がある下に貯蔵し、この貯蔵した廃棄物を天候を見計らって、入口20の反対側から前記屋根設備(長尺細幅シートの被覆シート18、平板17、網状金属板16等)と仮設用金属パイプ15の一部を解体して廃棄物を盛土状に埋め立てる。なお、悪天候の時は埋立作業を休んで廃棄物の上に防水シートを被せて置く。そして、前記解体した屋根設備と仮設用金属パイプ15は屋根設備がある下に保管しておいて別な区画で再利用する。
【0017】
また、埋立作業については、貯蔵した廃棄物を前記屋根設備の下で盛土状に埋め立てて、その後に仮設用金属パイプ15を引き抜き、前記屋根設備を解体する方法を用いることもできる。
【0018】
前記埋め立てた後、堰堤2の一部を崩して盛土状に埋め立てた廃棄物の上に覆土を施す。また、埋立地中央の廃棄物運搬通路14の上は網状金属板16を採用しているので明り取りになる。また、被覆シート18が複数の長尺細幅シートで構成されているので部分的に取り外すことができる。さらに、屋根設備が仮設用金属パイプ15、連結金具、網状金属板16、ベニヤ板等の平板17、長尺細幅シートの被覆シート18、ネットカバー19等で構成されているので建築コストや解体コストが安価である。
【0019】
本発明の屋根設備は以上のような構成を有しているので、強風や豪雪に耐える構造であり、屋根設備の下で貯蔵しておいた廃棄物の中間処理(石灰系の薬剤を混合して安定化させる処理)ができ、廃棄物の最終処分場専用の屋根設備なので多少の雨漏りがあっても許容されるものである。
また、内部に溜った雨水は廃棄物の中間処理に利用できるし、内部に溜った雨水を廃棄物の中間処理に利用しない場合は、天気の良い日には、屋根設備を簡単に解体できるので、屋根設備の一部を開放して埋立区画全体に雨水を散水することによって蒸発させることができる。
【0020】
【発明の効果】
本発明は、以上の構成を採用した結果、次のような効果を得ることができる。(1)廃棄物処分場を覆う屋根設備として、強風、雪等の重さに耐えることができるものである。
(2)廃棄物処分場を覆う屋根設備として、設備費が廉価である。
(3)埋立ピットの設置場所の制約をうけることがなく、強風が多い地域、寒冷地で問題なく簡単に対応できる。

BACKGROUND OF THE INVENTION
In the present invention, a mud mixed with a lime-based solidifying agent is applied to the inner surface of a waste disposal site to form an impermeable layer, and all waste is stabilized with a lime-based chemical agent at every disposal. The impermeable layer where sewage does not penetrate into the basement by stepping on and solidifying with heavy machinery, etc., is repeated to the ground level by repeating this work, and the upper part is buried with embankment using reformed and stabilized waste The present invention relates to a roof facility that covers a waste disposal site that is a landfill site by securing a space necessary for a landfill operation of the waste disposal site.
[0002]
[Prior art]
Conventionally, as a building structure that covers a waste disposal site, it has a shape that protrudes above the ground, so it has been designed to harmonize with the surrounding environment, and it is a fixed type tent that is always shut off from the outside world. There is a type of arch, truss, ramen, space frame, shell, suspension, hybrid, etc., and these can be opened and closed to control the environment by allowing rain and solar intrusion and atmospheric movement as necessary However, as an example, if a traveling rail is laid on both sides of a landfill pit for dumping waste over a section spanning an adjacent assembly yard, the bellows-type tent roof is contracted on the traveling rail in the assembly yard. While assembling the structure, a water shielding sheet for covering is attached to the inside of the bellows-type tent roof structure using a frame, and then the bellows-type Extending the roof structure in the direction of the running rail, and at the same time, extending the covering water shielding sheet and constructing a roof body that covers the landfill pit, and discarding it in the landfill pit After the landfill processing step of dumping and landfilling, and the dumping of waste in the landfill pit, the covering water shielding sheet is separated from the bellows-type tent roof structure to cover the landfill area A covering treatment process for laying a water shielding sheet and a landfill final treatment process for shrinking and removing the bellows-type tent roof structure and covering the top surface of the covering water shielding sheet, There is a landfill processing method (see, for example, Patent Document 1).
In addition, as a method of installing the covering facility, the type that covers the entire landfill site with one structure, and the landfill site is divided to cover only some sections, and the covering facility is moved and moved sequentially as landfill progresses. There are some types.

[0004]
[Problems to be solved by the invention]
The roof equipment in the conventional waste disposal site is a bellows type tent roof, and when assembled, there is an effect that can be built with a small area assembly yard, but in the case of the type where the entire landfill pit is covered with one tent roof, Since a large-capacity landfill can be created, the initial cost can be reduced due to the merit of scale. However, there are restrictions on the construction method, and it is necessary to cope with strong winds and the weight of snow. In addition, since there is no movement of covering facilities, stable environmental conservation can be achieved by continuing certain environmental management. On the other hand, maintenance and management facilities such as ventilation and lighting facilities and environmental conservation facilities are large-scale, Maintenance costs may increase. In addition, in the case of the type that divides the landfill pit and covers every section, a structure to divide the landfill is required, but each landfill becomes smaller, so the covering facility and leachate Construction costs such as processing equipment can be reduced. Moreover, the range used as a landfill can be limited, which is advantageous in terms of site use and environmental conservation. Furthermore, since it becomes a small landfill, management becomes easy. However, there is a drawback that the production cost increases as a whole.
[0005]
On the other hand, the roof equipment covering the waste disposal site according to the present invention is provided with a lime-based solidifying agent on the inner surface of the waste disposal site disclosed in Japanese Patent No. 3131684 which the inventor has already invented. The mixed mud is applied and dried and solidified to form a water-impermeable layer, and all waste is reformed and solidified by a reforming and solidifying facility every time it is disposed of, and then dumped by heavy machinery etc. The impervious layer does not penetrate into the underground, the natural rainwater collected on the upper surface is stored, pumped up and sent to a waste reforming / solidification facility, this operation is repeated to the ground level, and the upper part is Ventilation and maintenance facilities are small because of the roof equipment covering the waste disposal site covering the landfill pit treated by the landfill method of the waste disposal site landfilled by embankment using reformed and solidified waste The facility production costs and maintenance Costs are those that live at low cost. Also, there is no problem even if the ceiling height is limited depending on the location of the landfill pit.
[0006]
In view of such circumstances, the present invention can avoid the restrictions on the construction method, and there is no problem with the strong wind and the weight of snow. Moreover, it proposes a roof facility that does not require ventilation and maintenance facilities, can be small-scale, can reduce production costs, and solves the problem of ceiling height constraints.
[0007]
[Means for Solving the Problems]
The present invention is intended to solve the above-described problems, and employs the following technical means. In the invention according to claim 1, in the roof equipment covering the landfill pit for dumping waste, the selected flat soil is excavated to form a reclaimed land, a dam is built around the excavated soil, and the landfill Assemble the waste transport passage from the entrance to the opposite side in the center and assemble the remaining area vertically and horizontally so that the metal pipes, brackets and connecting brackets form a scaffold, and the height of the vertically installed metal pipe is approximately the height of the dam In addition, a mesh metal plate, punch metal, etc. are laid on the upper part of the central waste transport passage, and a flat plate, such as a veneer plate, is laid between the vertical metal pipe and the dam to the remaining dam. A technical means was adopted in which a covering sheet of a long narrow sheet was placed on a plate or a flat plate so that the end portions in the longitudinal direction overlap each other, and the entire roof equipment including these was covered with a net cover.
[0008]
In the invention of claim 2, a landfill is formed by excavating the selected flat soil, and a dam is built around the excavated soil, and the waste is conveyed from the entrance to the opposite dam in the center of the landfill. Form the passage and remove the waste transportation passage part by metal pipes, brackets, and fittings, and tentatively assemble like a scaffold vertically and horizontally to the height of the dam. A flat metal plate, punch metal, etc. is laid on the upper part of the plate, and a flat plate such as a veneer plate is laid between the assembled temporary scaffolding and the dam to the remaining dam. A technical means was adopted in which covering sheets of narrow width sheets were stretched side by side so that the ends in the longitudinal direction overlapped, and the entire roof equipment including these was covered with a net cover and the outer periphery was fixed.
[0009]
【Example】
First, the waste disposal site of the present invention will be briefly described.
It is a waste disposal site for using trash (mainly incinerated ash of combustible trash that has fallen out of the recycling circle) as a resource. This is not a “final disposal site”, but a “cement raw material storage facility”, which uses the same “calcium” as seashells to conserve the environment of the country, while disposing of waste to build a stable recycling society. It is a place.
[0010]
As shown in FIG. 2, as an operation before landfill, a selected flat land is excavated to form a landfill 1 (excavated land), a dam 2 is built outside by the excavated soil, and limestone 3 is formed on the foundation ground. The impermeable layer 4 is applied to the bottom and sides, and the water shielding sheet 5 is stretched on the top.
[0011]
Next, as shown in FIG. 3, the incineration ash 6 (see FIG. 4) stabilized with a lime-based chemical is reclaimed, the surface of the landfill layer is covered with a waterproof sheet 7, and the dam 2 is constructed of excavated soil. The cover 8 is applied to the top of the waterproof sheet 7 and the slope is greened 9 to protect the cover 8.
[0012]
Further, as shown in FIG. 4, as the work after the landfill, the incinerated ash 6 that has been stabilized by greening 10 the entire cover soil 8 is stored and used for the park or the like, and the stabilized incinerated ash 6 is recycled. It is recycled as a raw material for cement after establishing a society.
[0013]
This waste disposal site (storage-type disposal site that does not throw away garbage) is covered with earth dam 2 according to the size of excavation according to the size of the selected land, and water treatment in the center The facility 11 is provided, and the landfill 12 is divided into approximately four equal parts to form four landfill sections 13. The incinerated ash 6 stabilized with a lime-based chemical is then landfilled, and the four landfill sections 13 are landfilled. is there. Furthermore, as shown in FIG. 6, various shapes can be adopted according to the land.
[0014]
The black part is a water treatment facility, the white part is a landfill section, (a) (b) (c) (e) (g) (h) is four sections, (d) is 18 sections , (F) shows 26 sections. Needless to say, the number of other sections can be appropriately selected.
[0015]
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG.
FIG. 1 shows a first embodiment of the present invention, which is effective when installed in an area exposed to strong winds such as a typhoon or a snowy area.
As an example, a landfill 1 is formed by excavating a selected flat soil with a roof facility as shown in FIG. 1, and a dam 2 is built on the outer periphery with the excavated soil. The waste transport passage 14 leading to the opposite side is secured and the remaining range is assembled vertically and horizontally so that the scaffolding is assembled with the metal pipe 15, brackets, and connecting metal fittings, and the height of the vertically installed metal pipe 15 is approximately the height of the dam 2 Then, a net-like metal plate 16, punch metal, etc. are laid on the upper part of the waste transport passage 14 in the center of the landfill, and a flat plate such as a veneer plate is provided between the metal pipe 15 and the dam 2 which are vertically provided up to the remaining dam 2. 17 is laid, and a covering sheet 18 of a long narrow sheet is stretched on the net-like metal plate 16 and the flat plate 17 so that the end portions in the longitudinal direction overlap each other, and the entire roof equipment including these is covered with the net cover 19. Cover the waste disposal site Root equipment, such as Okinawa Prefecture, Kochi Prefecture, and other areas where typhoons often land can provide roofing equipment that can withstand wind pressure and that is not subject to construction laws and that covers waste disposal sites. .
[0016]
Since it has the above-described configuration, a flat plate 17 such as a veneer plate in which a certain amount of waste is stretched between the dams 2 as described above from the inlet 20 (see FIG. 2) to the back side on the opposite side and a net-like shape. A long thin sheet covering sheet 18 is placed on top of a metal plate 16 or the like and stored under a roof facility. The stored waste is weathered, and the roof facility ( A part of the long thin sheet covering sheet 18, the flat plate 17, the net-like metal plate 16, etc.) and the temporary metal pipe 15 is disassembled and the waste is buried in a banking shape. In case of bad weather, rest the landfill and put a waterproof sheet on the waste. The dismantled roof equipment and the temporary metal pipe 15 are stored under the roof equipment and reused in another section.
[0017]
Moreover, about the reclamation operation | work, the stored waste can be buried in the embankment form under the said roof installation, the metal pipe 15 for temporary construction is pulled out after that, and the method of dismantling the said roof installation can also be used.
[0018]
After the landfill, a part of the dam 2 is broken to cover the waste landfilled in the form of embankment. Further, since the mesh metal plate 16 is adopted above the waste transport passage 14 in the center of the landfill, it becomes clear. Moreover, since the covering sheet 18 is composed of a plurality of long narrow sheets, it can be partially removed. Furthermore, since the roof equipment is composed of a temporary metal pipe 15, a connecting metal fitting, a net-like metal plate 16, a flat plate 17 such as a veneer plate, a cover sheet 18 of a long narrow sheet, a net cover 19, etc., construction costs and dismantling costs Is cheap.
