Description

【0001】
【発明の属する技術分野】
この発明は、連続地中壁の構築時に供されて、当該連続地中壁の先行エレメントの接合鋼板の継手部に付着するスライムの除去を行う、連続地中壁のスライム除去装置に関する。
【0002】
【従来の技術】
従来、連続地中壁を構築する場合には、掘削溝にベントナイト等の安定液を充填しつつ掘削を行う泥水工法が多用されている。
この泥水工法は、形成された掘削溝に鉄筋かごを垂下させて建込むとともに、構築される連続地中壁の幅方向の側部面に接合鋼板を装着し、該鉄筋かごの垂直が保持された後にトレミー管からコンクリートが打設され、連続地中壁の構築が行われる、という工法である。
【0003】
掘削溝の壁面や接合鋼板の継手部には掘削機によって乱された土であるスライムが付着している。このような状態のままでコンクリートの打設を行った場合には、コンクリート内にスライムを巻き込みコンクリートの強度の低下を生じ、また構築後の連続地中壁にスライムが混在した場合には、スライムが水の通過経路となり止水性を低下させる等の問題が生じるために、スライムの十分な除去が絶対的な条件とされている。
【0004】
そこで、接合鋼板に付着するスライムの除去に主に採用される方法としては、以下の方法がある。
鉄筋かごを建込む際に用いられるクレーンにより吊り下げられ、掘削溝の壁面や接合鋼板の継手部に沿って下降するスライム除去装置において、
(1)このスライム除去装置に固定配置される高圧洗浄装置の高圧ノズルから洗浄液を吐出させて除去を行う方法、
(2)このスライム除去装置に固定配置される固定カッタを接合鋼板面に当接させてスライムを殺ぎ落とし除去を行う方法、
(3)このスライム除去装置に固定配置される固定ブラシを接合鋼板面に当接させてスライムの除去を行う方法、
等である。
【0005】
【発明が解決しようとする課題】
しかしながら、上記(1)の高圧ノズルにより除去を行う方法においては、高圧ノズルに供給される洗浄液の吐出圧の変動に伴って吐出量も変動するために、的確なスライムの除去が困難であり、また、高圧ノズルの吐出口から距離のある箇所にスライムが付着する場合には、その吐出量によっては除去処理は困難なものとなる。ここで仮に、確実な除去を図るために複数箇所に高圧ノズルを配置した場合には、その結果として吐出流量が増加して安定液中にスライムが分散することとなり、その回収には手間を要することとなる。
【0006】
一方、上記(2)の固定カッタによる殺ぎ落とし除去を行う方法においては、特に接合鋼板の継手部表面には、タイロッド固定用のナット等の突起物が突設されており、これらの突起物が固定カッタの障害となって円滑な殺ぎ落とし除去ができない。
【0007】
また、上記(3)の固定ブラシにより除去を行う方法においては、スライムがブラシ自体に付着して目詰まりを生じるために長時間の除去作業には適さないとともに、掘削溝の壁面や接合鋼板の継手部等との磨耗により変形が生じるため寿命が短いという欠点がある。
さらに、ブラシの毛先の長さによっては、接合鋼板と掘削溝底の角部に堆積する砕石を移動させることや、この砕石に付着するスライムの除去ができない、という欠点がある。
【0008】
このような事情に鑑み本発明はなされ、従来のスライム除去装置同様、高圧ノズルとブラシによるスライム除去装置ではあるが、ブラシの目詰まりを生ずることなく確実にスライムの除去ができ、また、接合鋼板と掘削溝底の角部に堆積する砕石の移動やこの砕石に付着するスライムの除去ができ、従って、後続して構築する地中壁の質の向上と止水性の向上を図ることができる、連続地中壁のスライム除去装置の提供を課題とするものである。
【0009】
【課題を解決するための手段】
本発明はこのような課題を解決するため、連続地中壁の構築時に供されて、当該連続地中壁の先行エレメントの接合鋼板の継手部に付着するスライムの除去を行う装置であって、
掘削溝内に配置され、前記接合鋼板に沿って下降する昇降体と、
前記昇降体に備えられ、前記接合鋼板に接触しつつその上下方向の往復回動によりスライムの除去を行うブラシと、
前記昇降体に備えられ、前記接合鋼板と掘削溝底部との角部に堆積する砕石等の移動とスライムの除去を行う高圧ノズルとから構成することである。
【0010】
【発明の実施の形態】
このような構成とする本発明に係る連続地中壁のスライム除去装置の実施の形態について、添付する図面に基づいて説明を行う。
【0011】
図1は本発明に係る連続地中壁のスライム除去装置の側面図、図2は図1の一部破断側面図である。
【0012】
図に示すスライム除去装置1は、連続地中壁の構築時に供されて、当該連続地中壁の先行エレメントE1の接合鋼板SPの継手部に付着するスライム3の除去を行う装置であって、
掘削溝内に配置され、前記接合鋼板SPに沿って下降する昇降体2と、
前記昇降体2に備えられ、前記接合鋼板SPに接触しつつその回動により前記スライム3の除去を行うブラシBと、
前記昇降体2に備えられ、前記接合鋼板SPと掘削溝底部との角部に堆積するスライム3aの除去と砕石3bの移動を行う高圧ノズルNにより構成されている。
【0013】
前記昇降体2は、先行エレメントE1の接合鋼板SPの側部に、その高さ方向に沿って突設されたガイドレールGに摺動を自在とするブラケット6を介して装着されていて、その摺動、即ち昇降体2の降下・上昇は地上に配置されるクレーン等のベースマシン(図示せず)からのワイヤーロープWの巻き上げ・巻き戻しの操作により行われる。昇降体2の降下速度は掘削溝の深さにもよるが、概ね2M/分程度の降下速度とするものである。
【0014】
また、軸受機構4に軸支されるブラシBは、ポリプロピレン等の材質若しくは同等以上の対磨耗特性に優れた材質からなり、概ねその線径を3ミリ程度とするとともにその長さを接合鋼板SPに接触する程度の長さとするものであって、その根元部位は軸支金具8により結束されている。
そして、この軸支金具8は軸受機構4に軸支されるとともにリンク機構9を介して油圧シリンダ5に連結されていて、この油圧シリンダ5の摺動作動により軸受機構4を回動軸として設定範囲内でのブラシBの往復回動が適宜回数をもって行われる。本実施の形態例においてはブラシBの往復回動数を8乃至10往復動/分とすることにより良好なスライム除去の結果が得られる。
【0015】
前記高圧ノズルNは、昇降体2の側面底部部位に固定、あるいはその吐出方向の調整を自在として配置されていて、昇降体2に配置される噴射用ポンプPに配管部材10を介して接続されている。この噴射用ポンプPの作動により高圧ノズルNから多量の高圧化された安定液が吐出され、接合鋼板SPと掘削溝底部との角部に堆積するスライム3aの除去と砕石3bの移動が行われる。
なお、この高圧ノズルNは接合鋼板SPと掘削溝底部との角部に堆積するスライム3aの除去と砕石3bの移動を目的として配置されているが、高圧ノズルNの昇降体2への装着を回動機構を介しての装着とすることにより、ブラシBの往復回動との併動とした場合には、接合鋼板SPに付着するスライム3は、さらに確実な除去が可能となる。
【0016】
このような連続地中壁のスライム除去装置1を用いて、接合鋼板SPに付着するスライム3、3aの除去および砕石3bの移動についての作用を説明する。
【0017】
後行するエレメントを構築するための掘削作業が完了すると、図示しない地上のクレーン等のベースマシンから吊り下げられている掘削機が巻き上げられて撤去される。そして、スライム除去装置1がベースマシンに連結されるとともに、図2に示す昇降体2がブラケット6を介して、先行エレメントE1の接合鋼板SPに突設されるガイドレールGに装着される。
【0018】
スライム除去装置1の運転準備が完了すると、前記ベースマシンの2M/分程度の下降運転と併せて、図2に示す油圧シリンダ5の摺動運転も開始される。この油圧シリンダ5の一端部は前述の如くリンク機構9を介して軸受機構4に軸支される軸支金具8に連結されているために、油圧シリンダ5の所定の摺動行程に伴って軸支金具8の所定角度の範囲内で、8乃至10往復/分程度の回動が行われる。
【0019】
前述の如くこの軸支金具8には、ポリプロピレン等の材質で線径を3ミリ程度であってその長さを接合鋼板SPに接触する程度の長さとするブラシBが結束されているために、軸支金具8の往復回動によりブラシBの先端部が接合鋼板SP面と接触し、従って、接合鋼板SPに付着するスライム3の除去が可能となる。そして、ベースマシンの下降運転に伴って、接合鋼板SPの上端部位から下端部位にかけてのスライム3の除去が可能となるとともに、ブラシBが回動するためにこの回動によってブラシBに付着するスライム3も振るい落とされ、ブラシB自体に目詰まりを生じることはない。
【0020】
この様にして、接合鋼板SPに付着するスライム3の除去が完了すると、スライム3は安定液中で沈殿し掘削溝の底部に堆積することとなるが、接合鋼板SPと掘削溝底部との角部には多くのスライム3aが堆積するとともに、掘削時に土中に含まれた砕石3bが当該箇所に落下して、この落下した砕石3bにスライム3aが付着して絡み合った状態となっている。
【0021】
このような状態におけるスライム3aの除去は、スライム除去装置1が接合鋼板SPの下端部位に位置すると、昇降体2に配置される噴射用ポンプPが作動して、この噴射用ポンプPに供給される安定液が高圧ノズルNから吐出される。そして、この高圧ノズルNから吐出される安定液が、前述の接合鋼板SPと掘削溝底部との角部に沈殿堆積するスライム3aや砕石3bを吹き飛ばし、スライム3aの除去と砕石3bの移動が行われる。
【0022】
【発明の効果】
以上説明を行った本発明の連続地中壁のスライム除去装置によれば次のような効果を奏する。
【0023】
(1)接合鋼板に当接させるブラシを回動自在とすることにより、その表面に突起物を突設状態とする接合鋼板の継手部であっても、突起物の下部に付着するスライムの除去ができ、ブラシに付着するスライムが振るい落とされブラシの目詰まりを生ずることなく確実にスライムの除去が可能となる。
(2)また、高圧ノズルをスライム除去装置の底面角部に配置することにより、接合鋼板と掘削溝底の角部に堆積する砕石に付着するスライムの除去と砕石の移動が可能となる。
(3)従って、後続して構築する連続地中壁の質の向上と止水性の向上を図ることが可能となる。

Conventionally, when a continuous underground wall is constructed, a mud construction method is often used in which excavation is carried out while filling excavation grooves with a stable liquid such as bentonite.
In this mud construction method, a reinforcing steel cage is suspended in the formed excavation groove, and a steel plate is attached to the side surface in the width direction of the continuous underground wall to be constructed, so that the verticality of the reinforcing steel cage is maintained. After that, concrete is cast from the tremy pipe, and a continuous underground wall is constructed.
[0003]
Slime, which is soil disturbed by the excavator, adheres to the wall surface of the excavation groove and the joint portion of the joined steel plate. When concrete is placed in such a state, slime is entrained in the concrete, resulting in a decrease in the strength of the concrete, and when slime is mixed in the continuous underground wall after construction, As a result, there is a problem that water becomes a passage route for water and the water stoppage is lowered. Therefore, sufficient removal of slime is an absolute condition.

In addition, when slime adheres to a location at a distance from the discharge port of the high-pressure nozzle, the removal process becomes difficult depending on the discharge amount. Here, if high-pressure nozzles are arranged at a plurality of locations for reliable removal, the discharge flow rate increases as a result, and slime is dispersed in the stable liquid. It will be.
[0006]
On the other hand, in the method of performing the killing and removal with the fixing cutter of (2) above, protrusions such as nuts for fixing tie rods are projected particularly on the joint surface of the bonded steel sheet, and these protrusions However, it becomes an obstacle to the fixed cutter and cannot be removed smoothly.
[0007]
Further, in the method of removing with the fixed brush of (3) above, the slime adheres to the brush itself and clogs it, so that it is not suitable for long-time removal work, and the wall of the excavation groove and the bonded steel plate There is a drawback that the life is short because deformation occurs due to wear with the joints and the like.
Furthermore, depending on the length of the brush tip, there is a drawback that the crushed stone deposited on the corners of the bonded steel plate and the bottom of the excavation groove cannot be moved, and the slime adhering to the crushed stone cannot be removed.
[0008]
In view of such circumstances, the present invention has been made, and it is a slime removing device using a high-pressure nozzle and a brush as in the conventional slime removing device, but it can surely remove the slime without causing clogging of the brush, and the bonded steel plate. It is possible to move the crushed stone deposited at the corner of the bottom of the excavation groove and remove the slime adhering to this crushed stone, and therefore it is possible to improve the quality of the underground wall to be constructed subsequently and improve the water stoppage. An object of the present invention is to provide a slime removing device for a continuous underground wall.
[0009]

The lifting body 2 is mounted on a side of the joining steel plate SP of the preceding element E1 via a bracket 6 that is slidable on a guide rail G that protrudes along the height direction thereof. Sliding, that is, lowering / raising of the lifting body 2 is performed by winding and unwinding the wire rope W from a base machine (not shown) such as a crane disposed on the ground. Although the descent speed of the lifting body 2 depends on the depth of the excavation groove, the descent speed is approximately 2 M / min.
[0014]
Further, the brush B pivotally supported by the bearing mechanism 4 is made of a material such as polypropylene, or a material having an equivalent or better anti-abrasion property, and has a wire diameter of about 3 mm and a length of the bonded steel plate SP. The base portion is bound by a shaft support fitting 8.
The shaft support 8 is pivotally supported by the bearing mechanism 4 and is connected to the hydraulic cylinder 5 via the link mechanism 9, and the sliding mechanism of the hydraulic cylinder 5 sets the bearing mechanism 4 as a rotation axis. The reciprocating rotation of the brush B within the range is performed at an appropriate number of times. In the present embodiment, a satisfactory slime removal result can be obtained by setting the reciprocating rotational speed of the brush B to 8 to 10 reciprocating movements / minute.
[0015]
The high-pressure nozzle N is fixed to the side surface bottom portion of the elevating body 2 or can be freely adjusted in the discharge direction, and is connected to the injection pump P arranged in the elevating body 2 via the piping member 10. ing.
