Description
【０００１】[0001]
本考案は、地盤を掘削する時に発生する掘削残土の処理装置に関する。 The present invention relates to an apparatus for treating excavated soil generated when excavating the ground.
【０００２】[0002]
地下鉄工事、共同溝工事、及び大規模な建設工事などにおいて地下構築のため の掘削作業を行うにあたり、近年は特に掘削時に水のでないソイル柱列工法など 、止水性の高い山留工法が広く使用されている。特に都市部では狭いスペース内 でも適用でき、作業工程の簡略化や工期の短縮を可能にする等の利点から、該工 法を利用した施工工事が多用されるようになった。 In recent years, when performing excavation work for underground construction such as subway construction, joint ditch construction, and large-scale construction work, the highly water-stopping mountain retaining method such as the soil column method without water during excavation has been widely used. Have been. Especially in urban areas, it can be applied even in narrow spaces, and the construction work using this method has come to be used frequently because of its advantages such as simplification of the work process and shortening of the construction period.
【０００３】 上記工法に用いられる削孔機では、所謂オーガと呼ばれるスクリュー式の切り 欠き刃のある掘削軸が１本乃至複数本並列して備えられており、これらのオーガ を回転させながら地盤を掘削して削孔を行う。この際、セメント系懸濁液を先端 より地盤中に注入しつつ削孔攪拌するため、その削孔内はソイルセメントで充填 されることになり、後にＨ形鋼などの芯材をその中に埋め込んでソイル柱列など にする。[0003] The drilling machine used in the above-mentioned construction method is provided with one or a plurality of excavating shafts having screw-type notched blades, which are so-called augers, arranged in parallel. Drill and drill holes. At this time, drilling and stirring are performed while the cement suspension is injected into the ground from the tip, so that the drilling is filled with soil cement, and a core material such as H-section steel is later inserted into it. Embed it into a column of soil.
【０００４】 このオーガなどによる掘削作業中に、ソイルセメントを含む（その他ベントナ イトや地盤改良材などを含むこともある）掘削によって削り取られた土砂などが 、掘削残土として地上に揚土される。このようにして発生した掘削残土は、一時 的に現場内にプールされて、随時産業廃棄物として処分される。この種の産業廃 棄物は、焼却処理ができないばかりか、最終処分地の確保など、その処理も近年 は特に社会問題化しつつある。[0004] During the excavation work using the auger or the like, earth and sand or the like removed by excavation including soil cement (and may also include bentonite or ground improvement material) is excavated to the ground as excavated residual soil. Excavated soil generated in this way is temporarily pooled on site and disposed of as industrial waste at any time. In recent years, this type of industrial waste cannot be incinerated, and its disposal, such as securing final disposal sites, has become a social issue in recent years.
【０００５】 特公昭６１−４０８１４号は、そのような問題を解決するための構成を開示し ており、それによると、地盤掘削中に生じる残土（セメントミルクなどを含む） を、地上で一旦ふるいにかけてさらにセメントやフライアッシュ等の土砂固結剤 を混ぜて成分調整を行った後、掘削軸引き上げ時に、該軸から削孔内に充填する ようにしている。Japanese Patent Publication No. 61-40814 discloses a configuration for solving such a problem. According to this configuration, residual soil (including cement milk and the like) generated during excavation of ground is once sieved on the ground. After adjusting the components by further mixing soil and sand binders such as cement and fly ash, the excavation shaft is filled into the borehole when the shaft is lifted.
【０００６】 それにより、掘削軸引き上げ後に生じた掘削孔内の空隙に、前記掘削残土が充 填されるため、該掘削残土を廃棄物として処理する量が少なくなる。[0006] Accordingly, the void in the borehole formed after the lifting of the drilling shaft is filled with the residual soil, thereby reducing the amount of the residual soil to be treated as waste.
【０００７】[0007]
しかし上記構成では、掘削孔内に埋め戻す残土の成分調整を行っているため、 その成分調整次第で、周囲のソイルセメントの成分と埋め戻された残土の成分と が異なり、設計強度上問題になることがある。また残土中のセメントなどの残留 数値などが一定でない場合が多く、成分調整で追加混合するセメントなどの量が 直ちに決定しづらいなどの問題もある。さらにその成分調整のための手間がかか り、その分作業時間も余計に必要となる。 However, in the above configuration, since the component of the residual soil backfilled in the borehole is adjusted, the component of the surrounding soil cement and the component of the backfilled residual soil differ depending on the component adjustment, which causes a problem in design strength. May be. In addition, the residual values of cement and the like in the residual soil are often not constant, and there is a problem that it is difficult to immediately determine the amount of the cement and the like to be additionally mixed by adjusting the components. In addition, it takes time to adjust the components, which requires extra working time.
【０００８】 またこの技術では、残土を埋め戻すために、掘削軸内部から該残土を地中に充 填させるようにしているため、ふるいにかける時に十分細かな粒子のものにして おかないと、掘削軸内及び該掘削軸に連通するホース内で目詰まりを起こし、ス ムーズな埋め戻しはできない。またそのふるいわけのための手間がかかり、その 分作業時間及び作業スペースも余計に必要となる。Further, in this technique, in order to refill the surplus soil, the surplus soil is filled into the ground from the inside of the excavation shaft. Therefore, it is necessary to make particles of sufficiently fine particles when sieving. Clogging occurs in the drilling shaft and in the hose communicating with the drilling shaft, and smooth backfilling is not possible. In addition, it takes time and effort to sift it, which requires extra work time and work space.
【０００９】 本考案は、従来技術の以上のような問題の解決を図って、掘削残土の処理を有 効に実施できる装置構成を提供せんとするものである。The present invention is intended to solve the above-mentioned problems of the prior art and to provide an apparatus configuration capable of effectively performing the processing of the excavated soil.
【００１０】[0010]
そのため本考案に係る掘削残土処理装置は、掘削時に発生する掘削残土を吸い 取る吸い上げポンプと、掘削軸引き上げと共にその下に生じた、または引き上げ 後に生じている掘削孔内の空隙に、該残土を充填する排出ポンプとを備えること を基本的特徴としている。 Therefore, the apparatus for treating excavated soil according to the present invention uses a suction pump for sucking excavated excavated soil generated during excavation and a gap between the excavated shaft and the hole in the excavated hole generated below or after the excavation. It is basically characterized by having a discharge pump for filling.
【００１１】 上記装置構成によれば、掘削時に発生する掘削残土を、吸い上げポンプで吸い 取っておき、掘削軸引き上げと共にその下に生じた、または引き上げ後に生じて いる掘削孔内の空隙に、排出ポンプにより、前記掘削残土を充填するため、該掘 削残土を廃棄物として処理する量が少なくなる。そればかりか、ソイルセメント などで構成される掘削残土は、掘削時、もともとソイル柱列などの構成要素とな るものであるため、特に成分調整などを必要とせず、そのまま使用しても強度上 問題になることはない。またその成分調整のための手間が不要になり、その分作 業時間も短縮される。[0011] According to the above-described apparatus configuration, excavated soil generated during excavation is sucked by a suction pump, and the excavation shaft is lifted, and a discharge pump is used to fill a gap formed in or below the excavation hole with the excavation shaft. In addition, since the excavated soil is filled, the amount of the excavated soil as waste is reduced. In addition, excavated soil consisting of soil cement, etc., originally becomes a component such as a soil column at the time of excavation. No problem. In addition, the labor for adjusting the components becomes unnecessary, and the work time is shortened accordingly.
【００１２】 請求項２に係る掘削残土処理装置は、前記吸い上げポンプと排出ポンプが１つ の正逆転可能なポンプで構成されることを特徴としている。[0012] In a second aspect of the present invention, the excavated soil treatment apparatus is characterized in that the suction pump and the discharge pump are configured as a single reversible pump.
【００１３】 上記構成では、両ポンプ構成を１つのポンプで兼ねる構成としているため、狭 い作業スペースに本装置構成を設置する場合でも、その設置スペースが小さくて 済むようになる。In the above configuration, since both pump configurations are combined with one pump, even when the present device configuration is installed in a narrow work space, the installation space can be reduced.
【００１４】[0014]
以上詳述した本考案の具体的実施形態につき説明する。図１及び図２は、本考 案の掘削残土処理装置の一実施形態に係る使用状態説明図である。図中１は掘削 孔、２は掘削軸であるオーガ、３は掘削残土、４ａは吸い上げポンプと排出ポン プの構成を兼ねる正逆転可能なポンプ、４ｂは該ポンプ４ａに接続されたホース 、５は貯留槽である。 A specific embodiment of the present invention described in detail above will be described. FIG. 1 and FIG. 2 are explanatory diagrams of a use state according to an embodiment of the excavated residual soil treatment device of the present invention. In the figure, 1 is an excavation hole, 2 is an auger as an excavation axis, 3 is excavated soil, 4a is a forward / reversible pump serving as a suction pump and a discharge pump, 4b is a hose connected to the pump 4a, 5 Is a storage tank.
【００１５】 図１に示す構成では、オーガ２を回転させながら地盤Ｅを掘削して掘削孔１を 構築している。この際、セメント系懸濁液をオーガ２先端より地盤中に注入しつ つ削孔しており、削られた土砂とセメント系懸濁液とが混練して、その掘削孔１ はソイルセメントで充填されることになる。In the configuration shown in FIG. 1, the ground E is excavated while rotating the auger 2 to construct the excavation hole 1. At this time, drilling was performed while pouring the cement suspension into the ground from the tip of the auger 2, and the shaved earth and sand and the cement suspension were kneaded, and the drill hole 1 was made of soil cement. Will be filled.
【００１６】 また同図では、この掘削時に発生し、地盤上に揚土される掘削残土３を、前記 ポンプ４ａ及びホース４ｂにより回収し、貯留槽５に溜めておく。In FIG. 1, excavated soil 3 generated during the excavation and excavated on the ground is collected by the pump 4 a and the hose 4 b and stored in the storage tank 5.
【００１７】 図２に示す構成では、所定の深さまで掘削が達進行した段階で、オーガ２を掘 削孔１から引き上げる。その際、オーガ２の下方の掘削孔１内に空隙が生ずるが 、本構成では、前記ポンプ４ａ及びホース４ｂにより、その空隙に向けて貯留槽 ５内の掘削残土３を供給し、充填する。その供給に際しては、ホース４ｂの放出 端をオーガ２の外周面に向けて上記掘削残土３を送り込む。そして該オーガ２の 回転と共に、スクリュー式の切り欠き刃の刃面に沿わせて、上記掘削残土３を供 給し、その周面を下降させる。尚、この埋め戻しの際、ホース４ｂについては、 貯留槽５側とオーガ２側を入れ替える必要がなく、ポンプ４ａの回転を逆にする だけで良い。In the configuration shown in FIG. 2, the auger 2 is pulled up from the excavation hole 1 when the excavation reaches a predetermined depth. At this time, a gap is formed in the excavation hole 1 below the auger 2. In this configuration, the pump 4a and the hose 4b supply and fill the excavated soil 3 in the storage tank 5 toward the gap. At the time of the supply, the excavated residual soil 3 is fed with the discharge end of the hose 4 b facing the outer peripheral surface of the auger 2. With the rotation of the auger 2, the above-mentioned excavated soil 3 is supplied along the blade surface of the screw-type notch blade, and the peripheral surface thereof is lowered. At the time of this backfilling, it is not necessary to exchange the hose 4b between the storage tank 5 side and the auger 2 side, and it is only necessary to reverse the rotation of the pump 4a.
【００１８】 上記構成では、オーガ２の引き上げと共にその下に生じた掘削孔１内の空隙に 、前記掘削残土３が充填され、該掘削残土３を廃棄物として処理する量が少なく なる。そればかりか、再度埋め戻されるソイルセメントなどで構成される掘削残 土３は、掘削時、もともとソイル柱列などの構成要素となるものであるため、特 に成分調整などを必要とせず、そのまま使用しても設計強度上問題を生ずること はない。また吸い上げポンプの構成と排出ポンプの構成を１つのポンプ４ａで兼 ねているため、狭い作業スペースに本装置構成を設置する場合でも、その設置ス ペースが小さくて済むようになる。さらにオーガ２の回転と共に、スクリュー式 の切り欠き刃の刃面に沿わせて、上記掘削残土３を送り込んでいるので、掘削残 土３がたとえ多少固化して塊状物になっていたとしても、粒子調整などを行う必 要がなく、またオーガ２やそれに連通するホースなどの目詰まりを起こすことも なく、スムーズにその空隙に充填できるようになる。さらに成分調整やふるい分 けの手間がなくなり、その分作業時間も短縮される。In the above-described configuration, the space in the excavation hole 1 formed below the auger 2 with the lifting of the auger 2 is filled with the excavated soil 3, and the amount of the excavated soil 3 to be treated as waste is reduced. In addition, the excavated soil 3 composed of soil cement, etc., which is backfilled, is originally a component such as a soil column at the time of excavation. Use does not cause any problem in design strength. In addition, since the structure of the suction pump and the structure of the discharge pump are shared by one pump 4a, even when the apparatus configuration is installed in a narrow work space, the installation space can be reduced. Further, with the rotation of the auger 2, the excavated soil 3 is fed along the cutting surface of the screw-type notch blade, so that even if the excavated soil 3 is slightly solidified into a lump, There is no need to adjust the particles, and the clogging of the auger 2 and the hose communicating therewith does not occur, so that the gap can be smoothly filled. In addition, labor for adjusting components and sieving is eliminated, and the working time is shortened accordingly.
【００１９】 その他、特公昭６１−４０８１４号の構成に比べて、ふるいにかける装置や成 分を調整する装置等の掘削残土を回収し調整するプラントなどが不要になる分設 置スペースを少なくすることができる。前述のように、当該工法が、特に都市部 における狭いスペースを利用して実施される地下鉄工事、共同溝工事、及び大規 模な建設工事などにおいて適用されるため、その利用価値は非常に高いものとな る。また余計な装置が不要になる分、組立時間も不要になったり、水洗いなどの メンテナンスも必要なくなる。さらに設備費用や現場への運搬費用も要らなくな る。In addition, as compared with the configuration of Japanese Patent Publication No. 61-40814, a space for separating and eliminating a plant for collecting and adjusting excavated soil such as a device for sieving and a device for adjusting the component is reduced. be able to. As mentioned above, this method is applied to subway works, joint ditch works, and large-scale construction works that are carried out using narrow spaces, especially in urban areas. It becomes. Also, as no extra equipment is required, assembly time is not required, and maintenance such as washing with water is not required. Furthermore, there is no need for equipment costs or transportation costs to the site.
【００２０】 尚、本構成では、掘削残土を一旦貯留槽５に溜めておくようにしているが、こ れに限られず、例えば地盤に穴を掘ってそこに直に仮置きしたり、他の方法で仮 置きしても良いことは言うまでもない。In the present configuration, the excavated soil is temporarily stored in the storage tank 5. However, the present invention is not limited to this. For example, a hole may be dug in the ground and temporarily placed there, Needless to say, the temporary storage may be performed by the method.
【００２１】 図３及び図４は、オーガ２が多軸の場合の本考案の掘削残土処理装置の使用状 態説明図である。基本的な使用の仕方は前記と同じなので、その詳細については 、省略する。FIG. 3 and FIG. 4 are explanatory views of the use state of the excavated soil disposal apparatus of the present invention when the auger 2 has multiple axes. Since the basic usage is the same as described above, the details are omitted.
