Description
本発明は、シートパイル（鋼矢板）、鋼管杭などの杭を地中に圧入して、杭列を構築する杭列施工システム及び杭列施工方法に関し、特に狭隘な敷地での施工を可能とする技術に関する。 The present invention relates to a pile row construction system and a pile row construction method for constructing a pile row by press-fitting piles such as sheet piles (steel sheet piles) and steel pipe piles into the ground, and enables construction particularly in a narrow site. Related to technology.
杭列の施工方法として、無振動・無騒音の圧入工法が知られており、また、狭隘地、水上、傾斜地での圧入工法の実施のため、圧入済みの杭列を利用するノンステージ工法が知られている。 The vibration method and noise-free press-in method are known as the pile row construction method, and the non-stage method using the press-fitted pile row is used for the press-in method in narrow, water and sloping land. Are known.
これは、圧入済みの杭列上に、圧入施工の進行方向前方から後方に、圧入機、パワーユニット、クレーン、杭搬送台車を配置し、それぞれ移動可能とする。
ここにおいて、圧入機は、圧入済みの杭列と連続する位置に杭を圧入する。パワーユニットは、圧入機の動力源（油圧源及び電源）となる。クレーンは、最後方の杭搬送台車により搬送される杭を吊り上げ、１８０°旋回して、最前方の圧入機に供給する。
In this, a press-fitting machine, a power unit, a crane, and a pile transport carriage are arranged on the pile row that has been press-fitted from the front to the rear in the direction of the press-fitting construction, and can be moved.
Here, the press-fitting machine press-fits the pile at a position continuous with the press-fitted pile row. The power unit is a power source (hydraulic power source and power source) of the press-fitting machine. A crane lifts the pile conveyed by the last pile conveyance carriage, turns 180 degrees, and supplies it to the forefront press-fitting machine.
特許文献１には、圧入済みの杭列上に、圧入施工の進行方向前方から後方に、圧入機（杭圧入引抜機）、パワーユニット（エンジンユニット）、クレーン（ブーム）、杭搬送台車（搬送車）を配置したものが開示されている。
特許文献１のクレーン（ブーム）は、杭を吊り上げて水平面内を旋回するのではなく、ブーム先端の保持体により杭を掴み、杭列を含む垂直面内を回動して、圧入機に供給するように構成されている。
In Patent Literature 1, a press-fitting machine (pile press-fitting / pulling machine), a power unit (engine unit), a crane (boom), a pile transporting carriage (carrying vehicle) on the pile row that has been press-fitted, from the front to the rear in the direction of press-fitting construction ) Is disclosed.
The crane (boom) of Patent Document 1 does not lift the pile and swivel in the horizontal plane, but grips the pile with the holding body at the tip of the boom, rotates it in the vertical plane including the pile row, and supplies it to the press-fitting machine Is configured to do.
しかしながら、上記の背景技術のうち、クレーンが１８０°旋回するものは、旋回スペースを確保する必要から、狭隘地での実施が困難となる。
また、クレーン（ブーム）を垂直面内で回動させるものは、クレーンと圧入機との間にパワーユニットがあるので、パワーユニットの上を越えて杭を供給することが難しく、実施は容易ではない。すなわち、杭を掴み、杭の姿勢を制御しつつ、移動させる必要があるが、杭の姿勢の制御は容易ではない。
However, among the above-mentioned background arts, a crane turning 180 ° is difficult to implement in a narrow area because it is necessary to secure a turning space.
Moreover, since the thing which rotates a crane (boom) in a vertical plane has a power unit between a crane and a press-fitting machine, it is difficult to supply a pile over a power unit and implementation is not easy. That is, it is necessary to grab the pile and move it while controlling the posture of the pile, but it is not easy to control the posture of the pile.
本発明は、このような実状に鑑み、クレーンへの杭の受け渡しを工夫することで、クレーンの旋回を最小角度にとどめ、狭隘地での施工を可能にすることを課題とする。 In view of such a situation, an object of the present invention is to devise the delivery of piles to a crane so as to keep the crane from turning at a minimum angle and enable construction in a narrow area.
上記の課題を解決するために、本発明に係る杭列施工システムは、圧入済みの杭列上に移動可能に設置される圧入機と、前記圧入機の後方で、圧入済みの杭列上に移動可能に設置され、杭を吊り上げて前記圧入機に供給可能なクレーンと、圧入済みの杭列に並行して設けられる補助走行路と、前記補助走行路上を移動可能で、前記クレーンに受け渡すため、杭を搬送する台車と、を含んで構成される。
ここにおいて、前記台車は、杭の長手方向を前記補助走行路の走行方向と一致させた状態で、杭の吊り上げ側の端部（すなわち、杭の両端部のうち、クレーンのワイヤを掛けて吊り上げる側の端部）が前記クレーンの旋回中心より前方に位置するように、杭を搬送することを特徴とする。
In order to solve the above-mentioned problem, a pile row construction system according to the present invention includes a press-fitting machine movably installed on a press-fitted pile row, and a press-fitted pile row behind the press-fitting machine. A crane that is movably installed and can lift a pile and supply it to the press machine, an auxiliary travel path that is provided in parallel with the press-fitted pile row, and is movable on the auxiliary travel path and delivered to the crane For this reason, it is comprised including the trolley | bogie which conveys a pile.
Here, the bogie is lifted by hanging the wire of the crane among the ends on the lifting side of the pile (that is, the both ends of the pile, with the longitudinal direction of the pile aligned with the traveling direction of the auxiliary traveling path) The piles are transported so that the end portion on the side is positioned forward of the turning center of the crane.
また、本発明に係る杭列施工方法は、圧入済みの杭列上に、圧入機とクレーンとを前後に設置し、圧入済みの杭列に並行して設けられる補助走行路により、杭の長手方向を前記補助走行路の走行方向に一致させた状態で、杭を搬送して、杭の吊り上げ側の端部を前記クレーンの旋回中心より前方に位置させ、この位置から、前記クレーンにより杭を吊り上げて、前記圧入機に供給することを特徴とする。 Moreover, the pile row construction method according to the present invention includes a press-fitting machine and a crane installed in front and back on a press-fitted pile row, and an auxiliary traveling path provided in parallel with the press-fitted pile row, With the direction matched to the traveling direction of the auxiliary travel path, the pile is transported, and the end of the pile lifting side is positioned forward from the turning center of the crane. From this position, the pile is moved by the crane. It is lifted and supplied to the press-fitting machine.
本発明によれば、杭列の側方に補助走行路を設ける必要があるものの、クレーンは補助走行路上の一位置（クレーンの旋回中心より前方の杭の吊り上げ側の端部の搬送位置）から、圧入機の杭受け入れ位置まで、最小角度を旋回すれば足り、補助走行路を超える旋回スペースを確保する必要はない。従って、狭隘地であっても、補助走行路さえ設けることができれば、実施可能であり、狭隘地での施工が可能となる。 According to the present invention, although it is necessary to provide an auxiliary traveling path on the side of the pile row, the crane is moved from one position on the auxiliary traveling path (conveying position of the end portion on the lifting side of the pile ahead of the turning center of the crane). It is only necessary to turn the minimum angle to the pile receiving position of the press-fitting machine, and it is not necessary to secure a turning space beyond the auxiliary travel path. Therefore, even if it is a narrow area, as long as an auxiliary traveling path can be provided, it can be implemented, and construction in a narrow area becomes possible.
以下、本発明の実施の形態について、詳細に説明する。
図１〜図３は本発明に係る杭列施工システムの一実施形態を示し、図１は側面図、図２は正面図、図３は工程別の平面図である。
尚、本実施形態では、杭として、図４（Ａ）に示すように、凹凸があり、両端に継ぎ手を有するシートパイル（鋼矢板）を用い、図４（Ｂ）に示すように、継ぎ手をつなげることで、シートパイルの列により土留壁を構築する。但し、これに限るものではなく、様々な形状のシートパイルを用いることができることはもちろん、鋼管杭などを用いることもできる。
Hereinafter, embodiments of the present invention will be described in detail.
1 to 3 show an embodiment of a pile row construction system according to the present invention. FIG. 1 is a side view, FIG. 2 is a front view, and FIG.
In addition, in this embodiment, as shown in FIG. 4 (A), as a pile, a sheet pile (steel sheet pile) which has an unevenness | corrugation and has a joint at both ends is used, and a joint is used as shown in FIG. 4 (B). By connecting, the retaining wall is constructed by the row of sheet piles. However, the present invention is not limited to this, and various types of sheet piles can be used, and a steel pipe pile or the like can also be used.
図１では、地盤Ｇに、既に、複数の杭（シートパイル）１が圧入され、土留壁の一部をなす杭列２が構築されている。本実施形態では、圧入済みの杭列２を利用し、杭列２に連続させて、更に新規の杭１を圧入することで、杭列（土留壁）２を延長する。 In FIG. 1, a plurality of piles (sheet piles) 1 have already been press-fitted into the ground G, and a pile row 2 forming a part of the retaining wall has been constructed. In this embodiment, the pile row (soil retaining wall) 2 is extended by press-fitting a new pile 1 in succession to the pile row 2 using the pile row 2 that has been press-fitted.
圧入済みの杭列２上には、圧入施工の進行方向前方から後方に、圧入機１０、クレーン２０、パワーユニット３０を配置し、これらはそれぞれ杭列２上を移動可能とする。 On the pile row 2 that has been press-fitted, a press-fitting machine 10, a crane 20, and a power unit 30 are arranged from the front to the rear in the direction of press-fitting construction, and these can be moved on the pile row 2 respectively.
圧入機１０は、杭列２上を移動し任意の位置でクランプ可能な本体１１と、本体１１の前方に設けられて圧入方向に往復動する杭チャック部１２と、を含んで構成される。杭チャック部１２は、杭１を掴んで下降する動作と、杭１を解放した状態で上昇する動作とを交互に繰り返して、杭１を圧入する。尚、図示は省略するが、圧入に際しては、オーガ掘削と圧入とを連動させるクラッシュパイル工法を採用するのが望ましい。 The press-fitting machine 10 includes a main body 11 that can move on the pile row 2 and can be clamped at an arbitrary position, and a pile chuck portion 12 that is provided in front of the main body 11 and reciprocates in the press-fitting direction. The pile chuck | zipper part 12 press-fits the pile 1 by repeating alternately the operation | movement which grasps the pile 1, and descend | falls and the operation | movement which raises the pile 1 in the released state. In addition, although illustration is abbreviate | omitted, in the case of press-fit, it is desirable to employ | adopt the crash pile construction method which links auger excavation and press-fit.
クレーン２０は、杭列２上を移動し任意の位置でクランプ可能な本体２１上に旋回体２２が搭載され、これらがクレーン２０のベースマシンをなす。旋回体２２は、伸縮可能でかつ傾動可能なブーム２３を備え、ブーム２３の先端部には吊り上げフック部２４が吊り下げられている。
クレーン２０は、吊り上げフック部２４により杭１を吊り上げて、圧入機１０に供給する。
The crane 20 is mounted on a main body 21 that can move on the pile row 2 and can be clamped at an arbitrary position, and these constitute a base machine of the crane 20. The revolving structure 22 includes a boom 23 that can be expanded and contracted and tiltable, and a lifting hook portion 24 is suspended from the tip of the boom 23.
The crane 20 lifts the pile 1 by the lifting hook portion 24 and supplies it to the press-fitting machine 10.
パワーユニット３０は、圧入機１０とは別ユニットで設けられ、圧入機１０の動力源（油圧源及び電源）となる。
パワーユニット３０は、杭列２上で、クレーン２０の後方に、移動可能に配置され、最前方の圧入機１０に対し、図示しない１５ｍ程度のホースで接続される。従って、ホースの届く範囲であれば、パワーユニット３０の位置は自由であり、圧入機１０の移動のたびにパワーユニット３０を移動させる必要はない。
The power unit 30 is provided as a separate unit from the press-fitting machine 10 and serves as a power source (hydraulic power source and power source) of the press-fitting machine 10.
The power unit 30 is movably disposed on the pile row 2 behind the crane 20 and is connected to the forefront presser 10 with a hose of about 15 m (not shown). Therefore, the position of the power unit 30 is arbitrary as long as the hose can be reached, and it is not necessary to move the power unit 30 every time the press-fitting machine 10 moves.
図２及び図３に示されるように、杭列２の側方には、地上に、杭列２に並行して補助走行路４０が設けられる。補助走行路４０は、杭１の圧入施工の進行に伴って敷設される。
そして、補助走行路４０上には、クレーン２０に受け渡すため、杭１を搬送する台車５０が配置される。
尚、補助走行路４０は、Ｃ型鋼（チャンネル鋼）、Ｉ型鋼などの鋼材により形成できるが、杭としてシートパイルを搬送する場合は、シートパイルを利用してもよい。すなわち、シートパイルを図４（Ａ）のように開口部を上向きにして敷設し、その凹溝内にて車輪付きの台車５０を走行させる。
As shown in FIGS. 2 and 3, an auxiliary traveling path 40 is provided on the ground side in parallel with the pile row 2 on the side of the pile row 2. The auxiliary travel path 40 is laid along with the progress of the press-fitting construction of the pile 1.
And on the auxiliary | assistant driving path 40, in order to deliver to the crane 20, the trolley | bogie 50 which conveys the pile 1 is arrange | positioned.
In addition, although the auxiliary | assistant driving path 40 can be formed with steel materials, such as C type steel (channel steel) and I type steel, when conveying a sheet pile as a pile, you may utilize a sheet pile. That is, the seat pile is laid with the opening facing upward as shown in FIG. 4A, and the wheeled carriage 50 is caused to travel in the groove.
台車５０は、杭１の長手方向を補助走行路４０の走行方向と一致させた状態で、すなわち、杭１を横に倒して補助走行路４０に向きを合わせた状態で、杭１を一端側から搬送する。
また、台車５０は、杭１の一端側を載置する前側台車５１と、杭１の他端側を載置する後側台車５２との、少なくとも２つに分割されている。
The cart 50 is in a state in which the longitudinal direction of the pile 1 coincides with the traveling direction of the auxiliary traveling path 40, that is, in a state in which the pile 1 is tilted sideways and aligned with the auxiliary traveling path 40, Transport from.
Further, the carriage 50 is divided into at least two parts: a front carriage 51 for placing one end of the pile 1 and a rear carriage 52 for placing the other end of the pile 1.
また、台車５０、特に後側台車５２は、駆動源を有する自走台車５３に互いのジョイント５２ａ、５３ａを介して切り離し可能に連結されている。自走台車５３は作業基地（杭のストックヤード）から杭１を搬送する場合に使用する。
従って、台車５０（５１、５２）は、自走台車５３が走行可能な場合は、自走台車５３に押されて走行するが、自走台車５３の幅員を確保できず自走台車５３が走行できない狭隘地では、自走台車５３から切り離されて、人力（手押し）で走行する。
Further, the carriage 50, particularly the rear carriage 52, is detachably connected to a self-propelled carriage 53 having a drive source via mutual joints 52a and 53a. The self-propelled carriage 53 is used when the pile 1 is transported from the work base (pile stock yard).
Accordingly, when the self-propelled carriage 53 can travel, the carriage 50 (51, 52) travels while being pushed by the self-propelled carriage 53, but the width of the self-propelled carriage 53 cannot be secured and the self-propelled carriage 53 travels. In confined areas where it is impossible, the vehicle is separated from the self-propelled carriage 53 and travels with human power (by hand).
但し、地盤Ｇが傾斜していて補助走行路４０が勾配を有する場合には、台車５０（５１、５２）の逆走を防止するため、台車５０（５１、５２）は進行方向にのみ走行可能とするとよい。その手段としては、スイッチ操作により走行方向（制動方向）を切換えることができるラチェットブレーキを用いるのが好ましい。杭１の搬送時は進行方向にのみ走行可能とするが、杭１の供給を終えて作業基地（杭のストックヤード）に戻すときは、スイッチ操作により戻り方向にのみ走行可能とするためである。 However, when the ground G is inclined and the auxiliary travel path 40 has a slope, the carriage 50 (51, 52) can travel only in the traveling direction in order to prevent the carriage 50 (51, 52) from running backward. It is good to do. As the means, it is preferable to use a ratchet brake capable of switching the traveling direction (braking direction) by a switch operation. When the pile 1 is transported, it can travel only in the traveling direction, but when the supply of the pile 1 is finished and returned to the work base (pile stock yard), it can travel only in the return direction by a switch operation. .
ここにおいて、台車５０（５１、５２）は、杭１の吊り上げ側の端部（一般には前側台車５１により搬送される杭１の一端部）がクレーン２０の旋回中心（旋回体２２の中心部）より前方（詳しくは斜め前方）に位置するように、杭１を搬送する。 Here, as for the trolley | bogie 50 (51, 52), the edge part (generally one end part of the pile 1 conveyed by the front side trolley | bogie 51) of the lifting side of the pile 1 is the turning center of the crane 20 (central part of the turning body 22). The pile 1 is conveyed so that it may be located further forward (in detail, diagonally forward).
また、クレーン２０のブーム２３は、圧入機１０の圧入位置（杭１の受け入れ位置）より所定距離（Ｓ）後方のクレーン２０の旋回中心から、前記所定距離（Ｓ）を旋回半径として、補助走行路４０上の一位置から、圧入機１０の杭１の受け入れ位置まで、旋回させる。
上記の補助走行路４０上の一位置が、クレーン２０による杭１の吊り上げ位置であり、台車５０（特に前側台車５１）は、杭１の吊り上げ側の端部をこの位置まで搬送する。
In addition, the boom 23 of the crane 20 is assisted by using the predetermined distance (S) as a turning radius from the turning center of the crane 20 at a predetermined distance (S) behind the press-fitting position of the press-fitting machine 10 (receiving position of the pile 1). It is made to turn from one position on the road 40 to the receiving position of the pile 1 of the press-fitting machine 10.
One position on the auxiliary traveling path 40 is a lifting position of the pile 1 by the crane 20, and the carriage 50 (particularly the front carriage 51) conveys the end of the lifting side of the pile 1 to this position.
図５及び図６は補助走行路４０及び台車５０（５１、５２）の具体例を示し、図５は断面図、図６は平面図である。
この例では、補助走行路４０としてシートパイルが開口部を上向きにして地盤Ｇ上に敷設されている。台車５０（５１、５２）は、底部に車輪５４を有し、また側部にガイドローラ５５を有して、補助走行路４０（シートパイル）の凹溝内を走行する。そして、台車５０（５１、５２）の上に、杭１としてのシートパイルが開口部を上向きにして載置されて、搬送される。
尚、後側台車５２と自走台車５３とはジョイント５２ａ、５３ａで切り離し可能に連結されている。後側台車５２にはラチェットブレーキ５６が装備されている。
5 and 6 show specific examples of the auxiliary travel path 40 and the carriage 50 (51, 52), FIG. 5 is a sectional view, and FIG. 6 is a plan view.
In this example, a sheet pile is laid on the ground G with the opening facing upward as the auxiliary travel path 40. The carriage 50 (51, 52) has a wheel 54 at the bottom and a guide roller 55 at the side, and travels in the recessed groove of the auxiliary travel path 40 (sheet pile). And the sheet pile as the pile 1 is mounted on the trolley | bogie 50 (51, 52) with an opening part facing upward, and is conveyed.
The rear carriage 52 and the self-propelled carriage 53 are detachably connected by joints 52a and 53a. The rear carriage 52 is equipped with a ratchet brake 56.
次に施工ステップについて説明する。
〔杭搬送工程〕
図３（Ａ）に示すように、台車５０（前側台車５１及び後側台車５２）に杭１を載せて搬送する。
Next, construction steps will be described.
[Pile transport process]
As shown to FIG. 3 (A), the pile 1 is mounted on the trolley | bogie 50 (the front side trolley 51 and the rear side trolley 52), and is conveyed.
詳しくは、前側台車５１に杭１の一端部を載せ、後側台車５２に杭１の他端部を載せる。尚、搬送時は、各台車５１、５２と杭１とをそれぞれロープ等で固縛して、脱落を防止する。
自走台車５３が走行可能な場合は、後側台車５２と自走台車５３とをジョイント５２ａ、５３ａにより連結し、自走台車５３により押して、前側台車５１及び後側台車５２により、杭１を搬送する。
Specifically, one end of the pile 1 is placed on the front carriage 51 and the other end of the pile 1 is placed on the rear carriage 52. In addition, at the time of conveyance, each trolley | bogie 51,52 and the pile 1 are each tied up with a rope etc., and drop-off is prevented.
When the self-propelled carriage 53 can travel, the rear carriage 52 and the self-propelled carriage 53 are connected by joints 52 a and 53 a, pushed by the self-propelled carriage 53, and the pile 1 is removed by the front carriage 51 and the rear carriage 52. Transport.
自走台車５３の幅員を確保できず自走台車５３が走行できない狭隘地では、後側台車５２と自走台車５３とを連結しているジョイント５２ａ，５３ａを切り離す。このとき、逸走防止用に、後側台車５２と自走台車５３とを適当な長さのロープで結ぶようにしてもよい。
この後は、前側台車５１、後側台車５２、あるいはこれらに固縛されている杭１を手押しなどして、前側台車５１及び後側台車５２により、杭１を搬送する。
In a confined area where the width of the self-propelled carriage 53 cannot be secured and the self-propelled carriage 53 cannot travel, the joints 52a and 53a connecting the rear carriage 52 and the self-propelled carriage 53 are disconnected. At this time, in order to prevent runaway, the rear carriage 52 and the self-propelled carriage 53 may be connected with a rope having an appropriate length.
After this, the pile 1 is conveyed by the front carriage 51 and the rear carriage 52 by manually pushing the front carriage 51, the rear carriage 52, or the pile 1 secured to them.
かかる搬送により、前側台車５１、すなわち杭１の一端部は、クレーン２０の旋回中心（旋回体２２の中心部）より、斜め前方に位置させる。この位置は、図３（Ｂ）に示すようにブーム２３を補助走行路４０側に旋回させたときの、ブーム２３の先端部の下方である。 With this conveyance, the front carriage 51, that is, one end of the pile 1 is positioned obliquely forward from the turning center of the crane 20 (the center of the turning body 22). This position is below the tip of the boom 23 when the boom 23 is turned toward the auxiliary travel path 40 as shown in FIG.
〔杭吊り上げ工程〕
次に、図３（Ｂ）に示すように、クレーン２０のブーム２３を補助走行路４０側へ旋回させ、前側台車５１により搬送された杭１の一端部の上方に位置させる。
[Pile lifting process]
Next, as shown in FIG. 3B, the boom 23 of the crane 20 is turned to the auxiliary traveling path 40 side and is positioned above one end of the pile 1 conveyed by the front carriage 51.
クレーン２０のブーム２３先端より吊り上げフック部２４を下降させ、吊り上げフック部２４に杭１の一端部をワイヤで連結する。そして、吊り上げフック部２４を巻き上げることにより、杭１を吊り上げる。この吊り上げ開始と同時に杭１の一端部は前側台車５１から離れて上方へ移動し、杭１の他端部は後側台車５２に載ったまま後側台車５２と共に前方に移動し、杭１は次第に起き上がり、最終的には真っ直ぐになって、後側台車５２から離れる。これにより、杭１の吊り上げが完了する。吊り上げ完了後は、前側台車５１及び後側台車５２を次の搬送のため後方へ戻す。 The lifting hook 24 is lowered from the tip of the boom 23 of the crane 20, and one end of the pile 1 is connected to the lifting hook 24 with a wire. And the pile 1 is lifted by winding up the lifting hook part 24. Simultaneously with the start of lifting, one end of the pile 1 moves away from the front carriage 51 and moves upward, and the other end of the pile 1 moves forward together with the rear carriage 52 while remaining on the rear carriage 52. Gradually get up and eventually straighten away from the rear carriage 52. Thereby, lifting of the pile 1 is completed. After completion of lifting, the front carriage 51 and the rear carriage 52 are returned to the rear for the next transport.
〔杭旋回・供給工程〕
次に、図３（Ｃ）に示すように、クレーン２０のブーム２３を圧入機１０側へ旋回させて、杭１を圧入機１０に供給する。
すなわち、補助走行路４０上で、ブーム２３先端により杭１を吊り上げた状態から、ブーム２３を旋回し、杭１を圧入機１０の杭受け入れ位置（杭チャック部１２）の上方へ移動させる。そして、吊り上げフック部２４と共に杭１を下降させ、圧入機１０の杭チャック部１２に杭１を受け渡す。受け渡し後、圧入機１０により杭１が圧入される。
[Pile turning / feeding process]
Next, as shown in FIG. 3C, the boom 23 of the crane 20 is turned to the presser 10 side to supply the pile 1 to the presser 10.
That is, the boom 23 is turned from the state where the pile 1 is lifted by the tip of the boom 23 on the auxiliary traveling path 40, and the pile 1 is moved above the pile receiving position (pile chuck portion 12) of the press-fitting machine 10. Then, the pile 1 is lowered together with the lifting hook portion 24, and the pile 1 is delivered to the pile chuck portion 12 of the press-fitting machine 10. After delivery, the pile 1 is press-fitted by the press-fitting machine 10.
尚、クレーン２０による杭１の吊り上げと圧入機１０への供給は、１本ずつ行うが、台車５０（５１、５２）による杭１の搬送は、複数本（例えば２本）ずつまとめて行うようにしてもよい。特に図４（Ａ）に示したようなシートパイルの場合は、開口部側を上（又は下）にすれば、重ね合わせて載せることが容易であるので、まとめて搬送しやすい。 In addition, lifting of the pile 1 by the crane 20 and supply to the press-fitting machine 10 are performed one by one, but conveyance of the pile 1 by the carriage 50 (51, 52) is performed collectively by a plurality (for example, two). It may be. In particular, in the case of a sheet pile as shown in FIG. 4A, if the opening side is set to the upper side (or the lower side), it is easy to superimpose and put them together, so that they can be easily conveyed together.
また、シートパイルを搬送する場合で、補助走行路４０の幅が制約を受ける場合は、シートパイルを横置きではなく縦置きにして、すなわち、図４（Ａ）のシートパイルを９０°回転させて、開口部を横向きにした状態で、搬送してもよい。 Further, when the sheet pile is transported and the width of the auxiliary travel path 40 is restricted, the sheet pile is placed vertically instead of horizontally, that is, the sheet pile shown in FIG. 4A is rotated by 90 °. Then, it may be transported in a state in which the opening is turned sideways.
本実施形態によれば、圧入済みの杭列２上に、圧入機１０とクレーン２０とを前後に設置し、圧入済みの杭列２に並行して設けられる補助走行路４０により、杭１の長手方向を補助走行路４０の走行方向に一致させた状態で、杭１を搬送して、杭１の吊り上げ側の端部をクレーン２０の旋回中心より前方に位置させ、この位置から、クレーン２０により杭１を吊り上げて、圧入機１０に供給するように構成した。これにより、狭隘地であっても、補助走行路４０さえ設けることができれば、実施可能であり、狭隘地での施工が可能となる。 According to this embodiment, the press machine 10 and the crane 20 are installed in front and rear on the press-fitted pile row 2, and the auxiliary travel path 40 provided in parallel with the press-fitted pile row 2 allows the pile 1 to The pile 1 is transported in a state in which the longitudinal direction coincides with the traveling direction of the auxiliary traveling path 40, and the end of the pile 1 on the lifting side is positioned forward from the turning center of the crane 20. Thus, the pile 1 is lifted and supplied to the press-fitting machine 10. Thereby, even if it is a narrow area, if it can provide even the auxiliary travel path 40, it can be implemented, and construction in a narrow area becomes possible.
また、本実施形態によれば、クレーン２０のブーム２３は、補助走行路４０上の一位置（クレーン２０の旋回中心より前方の杭１の吊り上げ側の端部の搬送位置）と、圧入機１０の杭受け入れ位置との間を旋回可能とすればよく、最小角度を旋回すれば足り、補助走行路４０を超える旋回スペースを確保する必要がなくなる。 In addition, according to the present embodiment, the boom 23 of the crane 20 has one position on the auxiliary travel path 40 (conveying position at the end on the lifting side of the pile 1 ahead of the turning center of the crane 20) and the press-fitting machine 10. It is sufficient to be able to turn between the pile receiving positions, and it is sufficient to turn the minimum angle, and it is not necessary to secure a turning space beyond the auxiliary travel path 40.
また、本実施形態によれば、パワーユニット３０は、クレーン２０の後方で、圧入済みの杭列２上に移動可能に配置される。従って、クレーン２０を圧入機１０に近づけて配置することが可能となる一方、パワーユニット３０の移動回数が減少し、作業工程の短縮化を図ることができる。 Moreover, according to this embodiment, the power unit 30 is arrange | positioned at the back of the crane 20 so that a movement on the press-fitted pile row 2 is possible. Therefore, the crane 20 can be disposed close to the press-fitting machine 10, while the number of movements of the power unit 30 is reduced, and the work process can be shortened.
また、本実施形態によれば、台車５０（５１、５２）は、駆動源を有する自走台車５３に切り離し可能に連結され、切り離し後は人力（手押し）で走行する構成とした。これにより、自走台車５３を使用可能な敷地では、これを有効利用でき、自走台車５３を使用できない狭隘地では、人力で操作可能となるように、切り離して小型化することができる。 Further, according to the present embodiment, the carriage 50 (51, 52) is detachably connected to the self-propelled carriage 53 having a drive source, and after the separation, the carriage 50 (manual push) is configured to travel. Thereby, in the site where the self-propelled carriage 53 can be used, this can be effectively used, and in a confined area where the self-propelled carriage 53 cannot be used, it can be separated and downsized so that it can be operated manually.
また、本実施形態によれば、台車５０（５１、５２）は、杭１の一端側を載置する前側台車５１と、杭１の他端側を載置する後側台車５２との少なくとも２つに分割されている。これにより、台車５０（５１、５２）を人力（手押し）での取り扱いが容易になるように小型化できる。従って、杭１の受け渡し（杭１の吊り上げ）後、台車５０（５１、５２）の作業基地（杭のストックヤード）への移動作業が容易となる。 Moreover, according to this embodiment, the cart 50 (51, 52) includes at least two of the front cart 51 on which one end side of the pile 1 is placed and the rear cart 52 on which the other end side of the pile 1 is placed. It is divided into two. Thereby, the cart 50 (51, 52) can be reduced in size so as to be easily handled by human power (hand-held). Therefore, after the pile 1 is delivered (pile 1 is lifted), the moving work of the carriage 50 (51, 52) to the work base (pile stock yard) is facilitated.
