Description

本発明は、埋め立て地等の軟弱地盤や地下水が生ずる悪条件の廃棄物処分場において廃棄物の減容（廃棄空間の拡大）や埋設廃棄を実現する廃棄物処理工法及び前記廃棄物処理工法に使用する掘削体に関するものである。   The present invention relates to a waste disposal method that realizes volume reduction (expansion of disposal space) and buried disposal in a poorly disposed waste disposal site that generates soft ground such as landfill or groundwater, and the waste disposal method. The present invention relates to an excavation body to be used.

一般廃棄物や産業廃棄物等のうち再利用されない廃棄物は、廃棄物処分場に投棄しているもので、投棄は単に従前の廃棄物の上になされ、廃棄物が順次積層されていくものである。放置しておくと自重による自然の圧縮以外に減容がなされない。このため処分場が満杯になると別の処分場を探さなければならない。   Waste that is not reused, such as general waste and industrial waste, is dumped in the waste disposal site, and dumping is simply performed on the previous waste, and the waste is sequentially stacked. It is. If left unattended, there is no reduction in volume other than natural compression by its own weight. For this reason, when the disposal site is full, another disposal site must be found.

そこで廃棄物処分場において、外周にコテ部を備えた掘削土砂圧密形のオーガ（掘削体）を使用して、無排出で掘削穿孔して圧密孔を形成し、前記圧密孔によって新たに廃棄物廃棄空間を形成し、当該空間に廃棄物を廃棄充填する廃棄物処理工法が知られている。   Therefore, in a waste disposal site, a drilled earth and sand compacted auger (excavated body) with a trowel on the outer periphery is used to form a consolidated hole by excavating and drilling without discharge. 2. Description of the Related Art There is known a waste processing method that forms a waste space and discards and fills the space with waste.

例えば特許文献１（特開平１０−２７２４３２号公報）には、圧密孔を形成した後に掘削体を孔内に差し入れた状態で逆回転をさせて引き抜きながら、孔口から廃棄物を投入し、孔底へと落下させながらコテ部（圧密板）で孔壁に圧密させ、更に残りを孔底に順次堆積させる手段が開示されている。   For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 10-272432), after forming a consolidation hole, waste is thrown in from the hole opening while the excavation body is inserted into the hole and rotated backward and pulled out. A means is disclosed in which a hole portion (consolidation plate) is pressed against a hole wall while dropping to the bottom, and the remainder is sequentially deposited on the hole bottom.

特許文献２（特開２００１−２８６８４３号公報）には、圧密コテ（圧密板）を周面に設けたケーシングと、このケーシング内を通し且つ先端から突出する掘削ヘッドを有する掘削ロッドとからなる掘削体を使用し、ケーシングの圧密コテで無排出掘削を行い、ケーシングを残した状態でケーシング内に表層廃棄物を投入し、後にケーシングを引き抜く廃棄物処理工法が開示されている。   Patent Document 2 (Japanese Patent Laid-Open No. 2001-286843) discloses a excavation comprising a casing provided with a consolidation trowel (consolidation plate) on the peripheral surface and a drill rod having a drill head passing through the casing and protruding from the tip. A waste processing method is disclosed in which a body is used, non-discharge excavation is performed with a compacting trowel of the casing, surface layer waste is put into the casing with the casing remaining, and the casing is later pulled out.

特許文献３（特開２００６−１５２６２号公報）には、無排出圧密孔を形成しオーガを引き抜いた後に、圧密孔に外周面が平滑なケーシングを立て込み、ケーシング内に廃棄物を投入充填しながら若しくは充填後にケーシングの引き抜きを行う処理工法が開示されている。   In Patent Document 3 (Japanese Patent Application Laid-Open No. 2006-15262), after forming an exhaustless compaction hole and pulling out the auger, a casing having a smooth outer peripheral surface is set up in the compaction hole, and waste is charged into the casing. However, a processing method is disclosed in which the casing is pulled out after filling.

更に特許文献４（特開２００８−３０２２７３号公報）には、圧密コテ部を周設した筒状本体の先端に、逆円錐台形状の掘削部を設けた掘削ヘッドと、前記掘削ヘッドと連続連結したケーシングとで圧密孔を形成保持し、掘削部材を引き抜いた後に圧密孔に廃棄物を投入する廃棄物処理工法が開示されている。   Further, Patent Document 4 (Japanese Patent Application Laid-Open No. 2008-302273) discloses a drilling head in which an inverted frustoconical drilling part is provided at the tip of a cylindrical body provided with a consolidation iron part, and a continuous connection with the drilling head. A waste treatment method is disclosed in which a compact hole is formed and held with the casing and the excavation member is pulled out, and then waste is put into the compact hole.

廃棄物処理場の地盤状況にあっては、前記した圧密孔を形成した際に、圧密孔に直ぐに地下水が侵入する場合がある。特に埋立地の廃棄物処理場では、埋め立てに際して浚渫土砂や建築廃材や焼却灰等の廃棄物で行われていたために、地盤自体が緻密ではなく堆積廃棄物が海水面下まで達している場合は、前記の圧密孔を掘削形成しても、直ぐに海水が浸透してきて圧密孔が崩壊してしまう。   In the ground situation of the waste disposal site, when the above-described consolidation hole is formed, there is a case where groundwater enters the consolidation hole immediately. Especially in landfill waste disposal sites, when the landfill was done with waste such as dredged soil, building waste and incineration ash, the ground itself was not dense and the accumulated waste reached below sea level. Even if the above-mentioned consolidation hole is formed by excavation, seawater immediately permeates and the consolidation hole collapses.

前記の状況下で特許文献１記載の工法を採用したとしても、ケーシングで圧密孔の孔壁を保持するものではないので、廃棄物投入作業時に圧密孔の孔壁が崩壊してしまう虞がある。しかも掘削体の先端ビットで態々堆積廃棄物を粉砕して圧密孔を形成する無駄があり、また掘削した圧密孔内に掘削体（オーガ軸）が存在する状態で、掘削孔への廃棄物の投入を行うため、孔底への通過断面が狭く廃棄物投入が効率的に行われない等、その作業効率の点に問題がある。   Even if the construction method described in Patent Document 1 is adopted under the above circumstances, the hole wall of the consolidation hole is not retained by the casing, and therefore there is a possibility that the hole wall of the consolidation hole may collapse during the waste charging operation. . Moreover, there is a waste of pulverizing the accumulated waste with the tip bit of the excavated body to form a consolidated hole, and in the state where the excavated body (auger shaft) exists in the excavated consolidated hole, There is a problem in terms of work efficiency, for example, because the cross-section to the bottom of the hole is narrow and waste input is not efficiently performed.

また地下水問題がある廃棄物処理場では、前記特許文献３記載の工法のように圧密孔形成後にケーシングを圧密孔に投入設置する手段では、ケーシングの設置前に圧密孔が崩壊してしまう虞があり、特許文献４記載の工法のように、掘削体を引き抜いて圧密孔自体の形状保持を前提とする手法では圧密孔の崩壊によって成立しない。   Further, in a waste disposal site where there is a groundwater problem, there is a possibility that the consolidation hole may collapse before the casing is installed by means of introducing the casing into the consolidation hole after forming the consolidation hole as in the construction method described in Patent Document 3. In addition, as in the construction method described in Patent Document 4, the method based on the assumption that the excavated body is pulled out and the shape of the consolidated hole itself is maintained cannot be established due to the collapse of the consolidated hole.

更に特許文献２記載の廃棄物処理工法のように、ケーシングを残したまま廃棄物投入を行う手段は、地下水問題には対応できるが、掘削体をケーシングと、掘削ロッド及び掘削ロッドからなる掘削部の二重構造が必要となり、而も回転駆動装置も掘削圧密時の掘削ロッド駆動機構とケーシング引抜時のケーシング駆動機構が必要となり、装置全体が複雑になってしまう。   Further, as in the waste treatment method described in Patent Document 2, the means for throwing in waste while leaving the casing can cope with the groundwater problem, but the excavating body is a excavation section comprising a casing, a excavation rod and an excavation rod. Therefore, the rotary drive device also requires a drill rod driving mechanism at the time of excavation compaction and a casing drive mechanism at the time of pulling out the casing, which complicates the entire apparatus.

そこで本発明は、地下水問題に対応できる新規な掘削体及び前記掘削体を使用する廃棄物処理工法を提案したものである。   Therefore, the present invention proposes a novel excavation body that can cope with the groundwater problem and a waste treatment method using the excavation body.

本発明に係る掘削体（請求項４）は、掘削部と１個又は複数のケーシングからなり、掘削部が、筒状本体の上端縁にケーシング接続部を設け、回転方向に対応して外周方向に張り出し、回転方向終端側が掘削孔と対応する径とした圧密板を複数備えると共に、下方開口部に閉口時に逆円錐形状となる開閉刺突部を設けてなり、ケーシングが、その上下端縁に前記掘削部又は他のケーシングと連続して接続する連結部を設けてなることを特徴とするものである。更に本発明の掘削体（請求項５）は、前記の掘削体において、掘削部の外周面における各圧密板の形成位置より下方に、螺旋間欠状に配置した攪拌羽根を設けてなるものである。   An excavation body according to the present invention (Claim 4) includes an excavation part and one or a plurality of casings, and the excavation part is provided with a casing connection part at an upper end edge of the cylindrical main body, and an outer peripheral direction corresponding to the rotation direction. And a plurality of compaction plates having a diameter corresponding to the excavation hole on the end side in the rotational direction, and an opening / closing piercing portion having an inverted conical shape when closed at the lower opening, and the casing is formed at the upper and lower ends of the casing. A connecting portion that is continuously connected to the excavating portion or another casing is provided. Furthermore, the excavated body of the present invention (Claim 5) is provided with stirring blades arranged in a spiral intermittently below the formation position of each compaction plate on the outer peripheral surface of the excavated part in the excavated body. .

本発明（請求項１）に係る廃棄物処分場における廃棄物処理工法は、前記掘削体を使用するもので、ケーシングの先部に掘削部を連結し、ケーシングを抱持して回転掘削する掘進機構を備えた掘削装置で、所望の深さの掘削孔を無排出で形成する掘削工と、前記掘削工の後に、ケーシング上部開口箇所から廃棄物を投入すると共に、開閉刺突部を開口してケーシングを順時引き抜いて、掘削孔に廃棄物を満たす埋め戻し工とを、掘削位置を変更して順次繰り返してなることを特徴とするものである。   The waste disposal method in the waste disposal site according to the present invention (Claim 1) uses the excavation body, and connects the excavation part to the front part of the casing, and holds the casing to rotate and excavate. Excavator with a mechanism to form an excavation hole with a desired depth without discharge, and after the excavation, waste is introduced from the upper opening of the casing and the opening and closing pierce is opened. Thus, the casing is pulled out in order and the backfilling work for filling the excavation hole with waste is sequentially repeated by changing the excavation position.

而して廃棄物処分場で掘削体を使用して圧密孔を形成し、掘削体をそのままにして廃棄物投入を行うものであるから、地下水（海水も含む）を含む層に達する深さまで圧密孔を形成しても、圧密孔の孔壁崩壊の虞が無い状態での廃棄物投入が可能となり、開閉刺突部を開放状態で掘削体を引き抜くことで、掘削体内の投入廃棄物は、圧密孔内に残される。   Thus, the excavated body is used to form a consolidation hole at the waste disposal site, and waste is input while leaving the excavated body as it is, so the consolidation is performed to a depth that reaches the layer containing groundwater (including seawater). Even if the hole is formed, it becomes possible to input the waste in a state where there is no risk of collapse of the hole wall of the consolidation hole, and by pulling out the excavated body with the opening and closing piercing part opened, the input waste in the excavated body is Left in the consolidation hole.

また本発明は、特に前記掘削部の外周面における各圧密板の形成位置より下方に、螺旋間欠状に配置した攪拌羽根を設けた掘削体を使用し、掘削時に孔壁面構成物を攪拌圧密して無排出掘削孔を形成してなるもので、無排出圧密孔の構築を速やかに行うことができたものである。   Further, the present invention uses a drilling body provided with stirring blades arranged in a spiral intermittently below the formation position of each compaction plate on the outer peripheral surface of the excavation part, and stirs and consolidates the hole wall structure during excavation. In this way, no discharge excavation holes are formed, and no discharge consolidation holes can be quickly constructed.

本発明は上記のとおりで、圧密孔を掘削して圧密孔に廃棄物投入を行うに際して、埋め立て地等の地下水層や海面下に達する悪条件の廃棄処分場でも、圧密孔を維持した状態での廃棄物投入が可能となったもので、廃棄物減容処理は勿論のこと、埋め立て地等への直接の廃棄物埋設処理をも実現したものである。   The present invention is as described above, and when the consolidation hole is excavated and waste is put into the consolidation hole, the consolidation hole is maintained even in a groundwater layer such as a landfill or a waste disposal site that reaches under the sea level. In addition to waste volume reduction processing, direct waste burying processing in landfills and the like has also been realized.

次に本発明工法の実施の形態について説明する。本発明の実施装置は、掘削体１と、掘削装置２と、バックホー３と、クレーン装置４で構成される。   Next, an embodiment of the method of the present invention will be described. The implementation apparatus of the present invention includes an excavation body 1, an excavation apparatus 2, a backhoe 3, and a crane apparatus 4.

実施形態として示した掘削体１は、掘削部１１と、２個のケーシング１２ａ，１２ｂで構成している。   The excavation body 1 shown as an embodiment is constituted by an excavation part 11 and two casings 12a and 12b.

掘削部１１は、筒状本体１１１の上端縁にケーシング接続部１１２を設け、外周面に攪拌羽根１１３と圧密板１１４を設け、下端部分に開閉刺突部１１５を設けたものである。   The excavation part 11 is provided with a casing connection part 112 at the upper end edge of the cylindrical main body 111, an agitation blade 113 and a compaction plate 114 on the outer peripheral surface, and an opening / closing piercing part 115 at the lower end part.

攪拌羽根１１３は、掘削孔（圧密孔）Ａと対応する外径で、螺旋状で且つ間欠的に設けたものである。圧密板１１４は、攪拌羽根１１３の上方に回転方向終端側が掘削孔Ａと対応する径で、且つ回転方向に対応して順次上方に設け、上下位置でその一部が重なるように複数周設したものであり、開閉刺突部１１５は、筒状本体１１１の下方開口部に閉口時に逆円錐形状となるものである。   The stirring blade 113 has an outer diameter corresponding to the excavation hole (consolidation hole) A and is provided spirally and intermittently. The compaction plate 114 is provided above the agitating blade 113 in a plurality of circumferences so that the end of the rotation direction has a diameter corresponding to the excavation hole A and sequentially above the rotation direction, and a part thereof overlaps at the vertical position. The opening / closing piercing portion 115 has an inverted conical shape when closed at the lower opening of the cylindrical main body 111.

ケーシング１２ａ，１２ｂは、筒状本体１１１と同一径で、上下端縁に前記掘削部１１及び他のケーシング１２ａ，１２ｂと互いに連続して接続する連結部１２１を設けてなるものである。   The casings 12a and 12b have the same diameter as the cylindrical main body 111, and are provided with connecting parts 121 connected to the excavation part 11 and the other casings 12a and 12b continuously at the upper and lower ends.

掘削装置２は、エクセル機と称される既存の装置で、前記ケーシング１２ａ，１２ｂを抱持して回転掘削する掘進機構２１を備えたものである。またバックホー３と、クレーン装置４は、周知の既存機器を使用する。   The excavation apparatus 2 is an existing apparatus called an excel machine, and includes an excavation mechanism 21 that holds the casings 12a and 12b and rotates and excavates them. The backhoe 3 and the crane apparatus 4 use well-known existing equipment.

次に前記実施装置を使用して本発明工法（施工作業）の実施について説明する。実施形態は、集積廃棄物Ｂが存在する処分場を例にしたが、埋め立て地のように直接廃棄物を埋設する場合にも本発明工法は適用されるもので、その場合、掘削対象は軟弱地盤となる。   Next, implementation of the present invention construction method (construction work) will be described using the above-described implementation apparatus. In the embodiment, the disposal site where the accumulated waste B exists is taken as an example. However, the present construction method is also applied to the case where the waste is buried directly like a landfill, in which case the excavation target is soft. It becomes the ground.

本発明工法の施工は、掘削工と埋め戻し工を実施するもので、掘削工は、掘削部１１とケーシング１２ａを連結した掘削体１を掘削装置２の掘進機構２１に装着し、掘削孔の掘穿予定位置において掘削を開始する。   The construction method according to the present invention involves excavation and backfilling. The excavator attaches the excavation body 1 connecting the excavation part 11 and the casing 12a to the excavation mechanism 21 of the excavation apparatus 2 to form the excavation hole. Drilling is started at the planned drilling position.

掘削は掘進装置２１で、掘削体１を回転させながら押し込むもので、掘削部１１の開閉刺突部１１５が閉口の逆円錐形の状態で集積廃棄物（又は軟弱地盤）Ｂに喰い込み、更に攪拌羽根１１３の作用で集積廃棄物Ｂ内に捻り込みながら集積廃棄物Ｂを攪拌して押し上げて掘進する。この掘進によって圧密板１１４で連続的に孔壁が押圧されて圧密状態となる。   The excavation is performed by the excavating device 21 while the excavating body 1 is rotated, and the opening / closing piercing portion 115 of the excavating part 11 bites into the accumulated waste (or soft ground) B in the closed conical state, and further The accumulated waste B is agitated and pushed up while being twisted into the accumulated waste B by the action of the stirring blade 113 to dig. By this excavation, the hole wall is continuously pressed by the compaction plate 114 to be in a compacted state.

特にケーシング１２ａ，１２ｂは筒状本体１１１と同径であるので、圧密孔Ａの孔壁との間に空隙が生し、掘削体１の掘進がスムーズに行われると共に、ケーシング１２ａによって圧密孔Ａの孔壁が多少崩壊しても掘削孔が維持されることになる。   In particular, since the casings 12a and 12b have the same diameter as the cylindrical main body 111, a gap is formed between the hole wall of the consolidation hole A, the excavation body 1 is smoothly advanced, and the consolidation hole A is formed by the casing 12a. Even if the hole wall of the hole collapses somewhat, the drilling hole is maintained.

掘削がある程度進行すると、ケーシング１２ａに次段のケーシング１２ｂをクレーン装置４で吊り上げて連結し、更に所定の深さまで掘削を行ない、掘削工を終了する（図２）。   When excavation progresses to some extent, the casing 12b of the next stage is lifted and connected to the casing 12a by the crane device 4, and further excavation is performed to a predetermined depth, thereby completing the excavation work (FIG. 2).

前記掘削工の後には、ケーシング１２ｂの上部開口箇所から、処分場への搬入廃棄物や処分場の表層廃棄物をかき集めた廃棄物Ｃを、バックホー３を使用して投入する。前記の廃棄物Ｃの投入に際して、クレーン装置４で吊下げたウエイトで投入廃棄物Ｄを填圧すると、より大量の廃棄物Ｃの投入が可能となる。   After the excavator, the waste C obtained by collecting the waste brought into the disposal site and the surface layer waste from the disposal site is introduced from the upper opening portion of the casing 12 b using the backhoe 3. When charging the waste C, if the input waste D is filled with the weight suspended by the crane device 4, a larger amount of the waste C can be input.

ある程度の廃棄物Ｃを投入すると、掘削体１の開閉刺突部１１５を開口して、掘進機構２１を逆転させて掘削体１を上方に移動させると、投入廃棄物Ｄは、そのまま圧密孔Ａに残存することになる。   When a certain amount of waste C is thrown in, the opening / closing piercing portion 115 of the excavating body 1 is opened, and when the excavating mechanism 21 is reversed to move the excavating body 1 upward, the thrown waste D is directly put into the consolidation hole A. Will remain.

掘削体１の上昇でケーシング１２ｂが露出すると、ケーシング１２ｂの連結を解除してクレーン装置４で吊り下げて取外し、再度ケーシング１２ａの上方開口部から廃棄物Ｃを投入する（図３）。圧密孔Ａを投入廃棄物Ｄで満たすと、掘削体１を全て引抜き、埋め戻し工を終了する（図４）。   When the casing 12b is exposed as the excavated body 1 is raised, the connection of the casing 12b is released and the casing 12b is suspended and removed by the crane device 4, and the waste C is again introduced from the upper opening of the casing 12a (FIG. 3). When the consolidation hole A is filled with the input waste D, the entire excavated body 1 is pulled out and the backfilling operation is completed (FIG. 4).

前記の掘削工及び埋め戻し工を終了すると、次の掘削予定位置に移動して、次の掘削工、埋め戻し工を順時実施し、これを繰り返すことで一杯となっている廃棄物処分場で更に大量の廃棄物を廃棄することができるものである（図５）。   After completing the excavation and backfilling, move to the next planned excavation position, carry out the next excavation and backfilling in order, and repeat this to complete the waste disposal site In this way, a larger amount of waste can be discarded (FIG. 5).

特に本発明は、形成した圧密孔Ａを掘削体１で保護した状態のまま圧密孔Ａ内への廃棄物投入を行うものであるから、圧密孔が崩壊しやすい埋め立て地等に設けた廃棄物処分場でも、何ら支障なく廃棄物減容処理が可能となったものであり、また近接地に連続して圧密孔Ａへの廃棄物投入減容処理が可能で作業効率も高められたものである。   In particular, according to the present invention, waste is provided in the consolidation hole A while the formed consolidation hole A is protected by the excavating body 1, so that the waste provided in a landfill or the like where the consolidation hole is likely to collapse. Even at the disposal site, it is possible to reduce the volume of waste without any problem, and it is possible to reduce the volume of waste into the compaction hole A continuously in the vicinity, improving work efficiency. is there.
