Description

【０００１】
【発明の属する技術分野】
本発明は、地盤に形成される切土や盛土の法面の設計勾配と、該法面ののり肩位置やのり尻位置とを表示するための丁張装置、及び、丁張装置を用いた法面の施工方法に関する。
【０００２】
【従来の技術】
一般に、切土又は盛土の法面を地盤に形成する場合、例えば、図５に示すように、設計上の計算値と、地盤Ｇの所定位置に設置された計量機器によって求められた計測値とで、切土や盛土の法面Ｎの施工を始める位置を地盤Ｇに設定し、のり肩やのり尻の位置に丁張装置を設置する。この丁張装置は、前後に立設される上下方向の水杭３０，３０と、該両水杭３０，３０に架設される水平方向の水ぬき板３１と、後方の水杭３０と水ぬき板３１とに傾斜して架設されるのりぬき板３２とから構成されている。なお、のりぬき板３２の基端部側の水杭３０に比して、のりぬき板３２の先端部側の水杭３０は低くなっている。
【０００３】
そして、丁張装置ののりぬき板３２の先端部により法面Ｎののり肩やのり尻の位置が示されることになり、のりぬき板３２の傾斜角度により法面Ｎの設計勾配が示され、この丁張装置に基づいて法面Ｎが地盤Ｇに形成されるようになっている。
【０００４】
また、従来の丁張装置としては、例えば、特開平５−１０７５９号に示すように、傾斜角度が調整可能に構成されると共に、直立されたシャフトを上下動可能に構成されたレーザ発光装置と、該レーザ発光装置の傾斜角度の調整、及び、高さの位置調整を遠隔より自動制御する遠隔操作装置を具備したものが公知になっている。
【０００５】
【発明が解決しようとする課題】
しかしながら、前者の場合、のりぬき板３２を、後方の水杭３０と水ぬき板３１とに傾斜して架設する際、作業員が釘をのりぬき板３２に直接打ち込んで固定しているため、その作業が煩雑であると共に、のりぬき板３２を精度よく固定するのが困難で、法面Ｎの施工に支障をきたすという問題がある。
【０００６】
また、後者の場合、レーザ発光装置を遠隔から自動制御する装置が必要となるため、非常に高価になるという問題がある。
【０００７】
そこで、本発明は上記問題点に鑑み、のりぬき板を精度よく容易に架設できると共に、法面の施工精度を向上できる安価な丁張装置及び丁張装置を用いた法面の施工方法を提供することを目的とする。
【０００８】
【課題を解決するための手段】
上記課題を解決するために、本発明の丁張装置は、請求項１に示す如く、切土や盛土の法面が形成される地盤に立設された水杭と、該水杭に架設される水平方向の水ぬき板と、水杭及び水ぬき板に傾斜して架設されるのりぬき板とを備え、のりぬき板の傾斜角度によって、前記法面の設計勾配が示されると共に、のりぬき板の先端部によって、法面ののり肩やのり尻の位置が示される丁張装置において、のりぬき板の基端部と、のりぬき板の基端部側に立設される水杭、又は、のりぬき板の基端部側に配される水ぬき板とに取り付けられた支持部材によって、のりぬき板の基端部を回動可能に支持すると共に、のりぬき板の先端部と、のりぬき板の先端部側に立設される水杭、又は、のりぬき板の先端部側に配される水ぬき板とに取り付けられた固定部材によって、のりぬき板の先端部を前記法面の設計勾配に合わせて固定するようにしたものである。
【０００９】
したがって、のりぬき板の基端部及び先端部が、取り付けられた支持部材や固定部材を介して水杭や水ぬき板に取り付けられるため、のりぬき板を精度よく容易に取り付けられる。
【００１０】
また、請求項２に示す如く、のりぬき板の基端部側に立設される水杭、又は、のりぬき板の基端部側に配される水ぬき板に打ち込まれる釘と、該釘に一体に形成された水平軸と、のりぬき板の基端部に取り付けられた水平軸の軸受けとで支持部材を構成し、のりぬき板の先端部側に立設される水杭、又は、のりぬき板の先端部側に配される水ぬき板に打ち込まれる釘と、該釘に一体に形成された水平軸と、のりぬき板の先端部に取り付けられた水平軸の軸受けとで固定部材を構成するようにしたものである。
【００１１】
例えば、設計上の計算値、及び、計量機器の計測値によって求めたのり肩やのり尻の位置を、のりぬき板の基端部側の水杭や水ぬき板に線引きをし、この線上に釘を打ち込めば、のりぬき板の基端部の正確な位置が容易に確保されることになる。さらに、設計計算によって求めた法面の設計勾配に合った位置を、のりぬき板の先端部側の水杭や水ぬき板に線引きをし、この線上に釘を打ち込めば、のりぬき板の勾配を法面の設計勾配に正確且つ容易に合わせられる。
【００１２】
さらに、請求項３に示す如く、支持部材及び固定部材の水平軸に、軸受けからの逸脱を防止するためのストッパを設けることが好ましい。
【００１３】
そうすれば、法面の施工が完了するまで、のりぬき板が安定した状態で保持されることになる。
【００１４】
加えて、請求項４に示す如く、丁張装置ののりぬき板の先端部の位置を調整する位置調整手段を固定部材に設けるようにしてもよい。
【００１５】
例えば、丁張装置ののりぬき板の先端部に、該のりぬき板の軸線方向に沿って長穴を形成する。さらに、ボルトの軸線がのりぬき板の軸線に対して直交するように、ボルトを長穴に挿通して移動可能にする。つぎに、該ボルトをのりぬき板の両側から挟持すべく、該ボルトに二つのナットを螺合させる。そして、法面の設計勾配と一致するのりぬき板の位置を、のりぬき板の先端部側に立設される水杭、又は、のりぬき板の先端部側に配される水ぬき板に設定する。その後、のりぬき板のボルトの位置が前記設定位置に位置するように調整して、のりぬき板のボルトの位置を固定する。また、長穴の代わりに、法面の設計勾配に合わせて設定された複数のガイド穴をのりぬき板の先端部に予め形成するようにしてもよい。
【００１６】
また、本発明の丁張装置を用いた法面の施工方法は、請求項５に示す如く、切土又は盛土の法面が形成される地盤に、設計上の計算値と、計量機器の計測値とで、前記法面ののり肩やのり尻の位置を設定し、つぎに、のり肩やのり尻の位置に水杭を前後に離間させて立設すると共に、該両水杭に、水ぬき板を上下に離間させて架設し、そして、支持部材を、のりぬき板の基端部と、のりぬき板の基端部側に立設される水杭、又は、のりぬき板の基端部側に配される水ぬき板とに取り付けて、のりぬき板の基端部を回動可能に支持すると共に、固定部材を、のりぬき板の先端部と、のりぬき板の先端部側に立設される水杭、又は、のりぬき板の先端部側に配される水ぬき板とに取り付けて、のりぬき板の先端部を前記法面の設計勾配に合わせて固定し、固定されたのりぬき板に基づいて前記法面を地盤に形成するようにしたものである。
【００１７】
この場合、丁張装置の設置作業が短時間で行われ、しかも、正確な勾配を有する法面を地盤に形成することができると共に、法面の施工作業が円滑に行われる。
【００１８】
【発明の実施の形態】
本発明の一実施形態につき、図１〜図４を参照して説明する。
本発明の丁張装置は、切土や盛土の法面Ｎが形成される地盤Ｇに前後に立設された二本の上下方向の水杭１，１と、該両水杭１，１に上下に架設される二本の水平方向の水ぬき板２，２と、上側の水ぬき板２と、下側の水ぬき板２とに傾斜して架設されるのりぬき板３と、のりぬき板３の基端部、及び、のりぬき板３の基端部側、即ち上側の水ぬき板２の後側に取り付けられた支持部材５と、のりぬき板３の先端部、及び、のりぬき板３の先端部側、即ち下側の水ぬき板２の前側に取り付けられた固定部材１５とから構成されている。
【００１９】
そして、上下の水ぬき板２，２は、図１に示すように、間隔Ｈが一定の寸法に保持されるように、水平に、且つ、平行に釘など（図示せず）によって取り付けられている。さらに、下側の水ぬき板２の前側の上面、及び、のりぬき板３の先端部側の下面には、のりぬき板３の傾斜角度を容易に設定できるように、複数のガイド穴１３，…、２３，…が予め形成されている。
【００２０】
支持部材５は、上側の水ぬき板２の後側に打ち込まれる平釘６と、該平釘６の略中央部に一体に溶着された水平軸７と、該水平軸７が挿脱可能に且つ回動可能に支持される軸受け８と、該軸受け８が固着された平面視矩形状の取付板９とを備えている。そして、水平軸７の先端部には、軸受け８からの逸脱を防止する樹脂製の環状のストッパ１０が嵌脱可能に嵌入されている。さらに、取付板９の両端部には、取付穴１１，１１が穿設され、該両取付穴１１，１１には、二重頭釘１２，１２が打ち込まれて取付板９がのりぬき板３の基端部側の下面に固定される。
【００２１】
固定部材１５は、支持部材５と同様の構成になっており、のりぬき板３の先端部側、即ち下側の水ぬき板２の前側に打ち込まれる平釘１６と、該平釘１６に一体化された水平軸１７と、該水平軸１７の軸受け１８と、該軸受け１８が固着された取付板１９とを備え、水平軸１７の先端部にストッパ２０が嵌入されると共に、取付板１９が二本の二重頭釘２２によってのりぬき板３の先端部側の下面に固定される。
【００２２】
つぎに本発明の丁張装置を用いた法面Ｎの施工方法について説明する。まず、従来と同様に、切土や盛土の法面Ｎが形成される地盤Ｇの所定位置に計量機器を設置し、該計量機器によって、計量機器の設置位置から法面ののり肩やのり尻の位置までの水平距離を求めると共に、計量機器の設置位置から法面ののり肩やのり尻の位置までの高さを求める。つぎに、計量機器の前記各計測値と、設計上の傾斜角度や計算値とで、法面ののり肩やのり尻の位置を地盤に設定する（図示せず）。
【００２３】
その後、設定した法面ののり肩やのり尻の位置の近傍に、丁張装置の二本の水杭１，１を前後に離間させて立設し、続いて、水平方向の二本の水ぬき板２，２を上下に離間させて両水杭１，１に直交して架設する。この状態で、上側の水ぬき板２の後側に、支持部材５としての平釘６を打ち込む一方、のりぬき板３の基端部の下面に、軸受け８が固着された取付板９を固定する。つぎに、平釘６に一体化された水平軸７に取付板９の軸受け８を挿通し、軸受け８を貫通した水平軸７の先端部にストッパ１０を嵌入し、のりぬき板３の基端部を回動可能に支持する。
【００２４】
この際、のりぬき板３の基端部の位置は、上側の水ぬき板２に固定された支持部材５の水平軸７によって決定されているため、誤差を生じることがない。
【００２５】
つぎに、法面Ｎの設計勾配に合わせてのりぬき板３の先端部を回動して調整し、下側の水ぬき板２のガイド穴２３，…を適宜選択して、即ちのりぬき板３の傾斜角度と法面Ｎの設計勾配とが一致するガイド穴２３，…を選択し、固定部材１５としての平釘１６を打ち込む一方、前記と同様に、のりぬき板３の先端部の下面のガイド穴１３，…を適宜選択して、のりぬき板３の先端部の下面に取付板１９を固定し、下側の水ぬき板２に固定された水平軸１７に、のりぬき板３に固定された取付板１９の軸受け１８を介してのりぬき板３の先端部を固定する。なお、この場合も、軸受け１８を貫通した水平軸１７には、ストッパ２０が嵌入されている。この際、のりぬき板３の先端部の位置は、下側の水ぬき板２に固定された固定部材１５の水平軸１７によって決定されているため、誤差を生じることがない。
【００２６】
そして、のりぬき板３を固定すれば、法面ののり肩やのり尻における丁張装置の設置作業が完了する。
【００２７】
なお、のりぬき板３の先端部の位置は、計量機器で求めた計測値、即ち計量機器の設置位置から法面ののり肩やのり尻の位置までの水平距離、及び、計量機器の設置位置から法面ののり肩やのり尻の位置までの高さと、設計計算で求めた法面Ｎの設計勾配とに基づき、三角関数を利用して容易に設定できる。
【００２８】
このように、本発明の丁張装置によれば、のりぬき板３を水杭１，１や水ぬき板２，２に直接固定することがないため、のりぬき板３の固定が正確に且つ容易に行われることになる。また、のりぬき板３の支持部材５や固定部材１５は、簡単な構成であり、安価である。
【００２９】
なお、前記実施形態の場合、のりぬき板３を用いて丁張装置を設置するようにしたが、支持部材５及び固定部材１５の平釘の代わりに二重頭釘を使用すると共に、のりぬき板３の代わりに糸や紐を用いてもよい。この場合、二重頭釘を、前後に立設された水杭１，１、又は、上下に配された水ぬき板２，２の所望の位置、即ち両二重頭釘に張設される糸や紐の傾斜角度と法面Ｎの設計勾配とが一致する位置に打ち込む。
【００３０】
また、前記実施形態の場合、支持部材５及び固定部材１５として、平釘６，１６に一体化された水平軸７，１７を用いたが、要するに、支持部材５及び固定部材１５としては、水平軸７，１７を、のりぬき板３の基端部側及び先端部側の水杭１，１や水ぬき板２，２に正確に固定できる構造のものであればよい。例えば、二つの固定穴を有する水平軸を使用し、のりぬき板３の基端部側及び先端部側の水杭１，１や水ぬき板２，２に固定するようにしてもよい。即ち、のりぬき板３を水杭１，１や水ぬき板２，２に直接固定しなければよい。さらに、前記実施形態の場合、図１において、のりぬき板３の基端部を上側、先端部を下側としたが、のりぬき板３の基端部を下側、先端部を上側としてもよい。この場合、下側の基端部を回動可能に支持した後、上側の先端部を固定するようにしてもよい。
【００３１】
【発明の効果】
以上説明したように、本発明の丁張装置によれば、丁張装置ののりぬき板の基端部と、のりぬき板の基端部側に立設される水杭、又は、のりぬき板の基端部側に配される水ぬき板とに取り付けられた支持部材によって、のりぬき板の基端部を回動可能に支持すると共に、のりぬき板の先端部と、のりぬき板の先端部側に立設される水杭、又は、のりぬき板の先端部側に配される水ぬき板とに取り付けられた固定部材によって、のりぬき板の先端部を法面の設計勾配に合わせて固定するようにしたため、のりぬき板を誤差を生じることなく安定した状態で簡単に取り付けられる。
【００３２】
また、のりぬき板の基端部側に立設される水杭、又は、のりぬき板の基端部側に配される水ぬき板に打ち込まれる釘と、該釘に一体に形成された水平軸と、のりぬき板の基端部に取り付けられた水平軸の軸受けとで支持部材を構成し、のりぬき板の先端部側に立設される水杭、又は、のりぬき板の先端部側に配される水ぬき板に打ち込まれる釘と、該釘に一体に形成された水平軸と、のりぬき板の先端部に取り付けられた水平軸の軸受けとで固定部材を構成するようにしたため、のりぬき板の基端部を正確な位置に容易に取り付けることができると共に、のりぬき板の勾配を、法面の設計勾配に正確且つ容易に合わせることができる。
【００３３】
さらに、支持部材及び固定部材の水平軸に、軸受けからの逸脱を防止するためのストッパを設けるようにしたため、法面の施工が完了するまで、のりぬき板を安定した状態で保持することができる。
【００３４】
加えて、丁張装置ののりぬき板の先端部の位置を、固定部材に設けられた位置調整手段によって調整するようにしたため、のりぬき板の先端部を、法面の設計勾配に合わせて容易に固定することができる。
【００３５】
また、本発明の法面の施工方法によれば、本発明の丁張装置を使用して法面を地盤に形成するようにしたため、丁張装置の設置作業を短縮できると共に、法面の施工精度を向上することができる。

[0005]
[Problems to be solved by the invention]
However, in the former case, when the glue board 32 is erected and installed on the rear water pile 30 and the water board 31 in an inclined manner, the worker directly nails the nail into the glue board 32 and fixes it. The work is complicated, and it is difficult to fix the glued plate 32 with high accuracy, which causes a problem in that the construction of the slope N is hindered.
[0006]
In the latter case, a device for automatically controlling the laser light emitting device from a remote place is required.
[0007]
In view of the above-mentioned problems, the present invention provides an inexpensive tensioning device and a method of constructing a slope using the tensioning device, which can easily and accurately install a glued plate and improve the accuracy of slope construction. The purpose is to do.
[0008]

[0014]
In addition, as described in claim 4, the fixing member may be provided with a position adjusting means for adjusting the position of the leading end of the stripping plate of the tensioning device.
[0015]
For example, an elongated hole is formed at the tip of the gluing plate of the drawing device along the axial direction of the gluing plate. Further, the bolt is inserted into the elongated hole so as to be movable so that the axis of the bolt is orthogonal to the axis of the strip. Next, two nuts are screwed into the bolt so as to clamp the bolt from both sides of the gluing plate. Then, the position of the seaming plate that matches the slope of the slope is set to a water pile that is erected on the tip end side of the seaming plate or a seawater plate that is arranged on the front end side of the seaming plate.

First, in the same manner as before, a weighing device is installed at a predetermined position on the ground G where the slope N of the cut or embankment is formed. In addition to calculating the horizontal distance to the position, the height from the installation position of the weighing device to the position of the shoulder and the buttocks on the slope is also found. Next, the positions of the shoulders and the buttocks on the slope are set on the ground based on the measured values of the weighing device and the designed inclination angles and calculated values (not shown).
[0023]
After that, two water piles 1, 1 of the tensioning device are erected in the vicinity of the set shoulder and the bottom of the set slope with the front and back separated from each other. The boring plates 2 and 2 are vertically separated from each other and are installed orthogonally to the water piles 1 and 1. In this state, a flat nail 6 serving as a support member 5 is driven into the rear side of the upper water-draining plate 2, and a mounting plate 9 to which a bearing 8 is fixed is fixed to a lower surface of a base end portion of the gluing plate 3. I do. Next, the bearing 8 of the mounting plate 9 is inserted into the horizontal shaft 7 integrated with the flat nail 6, and the stopper 10 is fitted into the distal end of the horizontal shaft 7 that has penetrated the bearing 8, and the base end of the stripping plate 3. The part is rotatably supported.
[0024]
At this time, since the position of the base end of the gluing plate 3 is determined by the horizontal shaft 7 of the support member 5 fixed to the upper flushing plate 2, no error occurs.
[0025]
Next, the tip of the piercing plate 3 is rotated and adjusted in accordance with the design gradient of the slope N, and the guide holes 23,... Of the lower piercing plate 2 are appropriately selected. Are selected and the flat nail 16 as the fixing member 15 is driven in, and the lower surface of the tip end of the glue-cutting plate 3 is driven in the same manner as described above. .. Are appropriately selected, the mounting plate 19 is fixed to the lower surface of the tip of the gluing plate 3, and the horizontal shaft 17 fixed to the lower draining plate 2 and the gluing plate 3 The front end of the stripping plate 3 is fixed via the bearing 18 of the fixed mounting plate 19. In this case as well, a stopper 20 is fitted on the horizontal shaft 17 penetrating the bearing 18. At this time, since the position of the tip end of the gluing plate 3 is determined by the horizontal shaft 17 of the fixing member 15 fixed to the lower flushing plate 2, no error occurs.
[0026]
Then, when the gluing plate 3 is fixed, the installation work of the tensioning device on the slope shoulder or the glue end of the slope is completed.
[0027]
In addition, the position of the tip of the gluing plate 3 is a measured value obtained by the weighing device, that is, the horizontal distance from the installation position of the weighing device to the position of the slope shoulder or the butt of the slope, and the installation position of the weighing device. Can be easily set using a trigonometric function based on the height from to the position of the shoulder and the buttocks of the slope, and the design gradient of the slope N obtained by the design calculation.
[0028]
As described above, according to the drawing device of the present invention, since the gluing plate 3 is not directly fixed to the water piles 1, 1 or the flipping plates 2, 2, the fixing of the gluing plate 3 can be performed accurately and accurately. It will be easily done. Further, the support member 5 and the fixing member 15 of the gluing plate 3 have a simple configuration and are inexpensive.
[0029]
In the case of the above-described embodiment, the tensioning device is installed by using the gluing plate 3. However, instead of using the flat nails of the support member 5 and the fixing member 15, a double-headed nail is used. A thread or a string may be used instead of 3. In this case, the double-headed nails are placed at desired positions of the water piles 1, 1 erected in front and rear, or the water-draining boards 2, 2 arranged vertically, that is, a thread stretched on the double-headed nails. It is driven into a position where the inclination angle of the string and the design slope of the slope N match.
[0030]
In the embodiment, the horizontal shafts 7, 17 integrated with the flat nails 6, 16 are used as the support members 5 and the fixing members 15, but in short, the support members 5 and the fixing members 15 are horizontal. Any structure may be used as long as the shafts 7 and 17 can be accurately fixed to the water piles 1 and 1 and the water plates 2 and 2 on the base end side and the distal end side of the glue board 3. For example, a horizontal shaft having two fixing holes may be used and fixed to the water piles 1, 1 and the waterboards 2, 2 on the base end side and the distal end side of the gluing plate 3. That is, it is not necessary to directly fix the glue board 3 to the water piles 1, 1 and the water board 2, 2. Furthermore, in the case of the above embodiment, in FIG. 1, the base end of the cutting plate 3 is set to the upper side and the tip end is set to the lower side, but the base end of the cutting plate 3 may be set to the lower side, and the tip end may be set to the upper side. Good. In this case, the lower end may be rotatably supported, and then the upper end may be fixed.
