図５は、本発明に係るレーザ照射装置設置台の基準ピンに検尺棒を当接した状態を示す切断面図である。図５を用いてレーザ照射装置設置台１０の立坑への設置方法を説明する。下水道管等の配管は、所定の勾配となるように、設置位置及び高さが厳格に決められている。そして、地上の基準点から立坑中央に位置する配管の内側下頂部までの長さを管渠底高といい、この管渠底高となるように地上の基準点から立坑中央に向けて検尺棒５が挿入される。検尺棒５は目盛が付されている長尺な棒であり、検尺棒５の一端が０となるように目盛が付されている。
FIG. 5 is a cross-sectional view showing a state in which a measuring rod is in contact with a reference pin of the laser irradiation apparatus installation base according to the present invention. The installation method to the shaft of the laser irradiation apparatus installation stand 10 is demonstrated using FIG. Installation positions and heights of piping such as sewer pipes are strictly determined so as to have a predetermined gradient. The length from the ground reference point to the inner bottom top of the pipe located at the center of the shaft is called the pipe bottom height, and the scale is measured from the ground reference point toward the shaft center so that this pipe bottom height is reached. The bar 5 is inserted. The measuring bar 5 is a long bar with a scale, and the scale is attached so that one end of the measuring bar 5 becomes zero.
したがって、レーザ照射装置設置台１０の設置作業は、先ず、立坑内にいる作業者が、レーザ照射装置設置台１０を立坑の底面の中央位置に載置した後、検尺棒５の一端が基準ピン３に当接するようにする。ここで、検尺棒５の一端の一部は収容孔１３ａに収容されることによって、検尺棒５の一端側が基準ピン３以外の設置台本体に干渉するのを防いでいる。次に、地上にいる作業者は、地上の基準点の位置が、検尺棒５の他端側における目盛位置であることを立坑内にいる作業者に伝える。そして、立坑内にいる作業者は、検尺棒５の目盛位置が管渠底高よりも大きい場合には、レーザ照射装置設置台１０の４本のボルトにより形成された支持脚２、２・・が長くなる方向に回して調節し、検尺棒５の目盛位置と管渠底高とが一致するように調節する。また、検尺棒５の目盛位置が管渠底高よりも小さい場合には、レーザ照射装置設置台１０の４本のボルトにより形成された支持脚２、２・・が短くなる方向に回して調節し、検尺棒５の目盛位置と管渠底高とが一致するように調節する。尚、前述したように、レーザ照射装置設置台１０の補強板６、６の上面は、４本の支持脚２、２・・の長手方向と一致する仮想直線に対して垂直な面となるように設置されており、この補強板６、６の上面に水準器を設置して４本の支持脚２、２・・の長さを調節することによって、レーザ照射装置設置台１０を精度よく設置することができる。
Therefore, the installation work of the laser irradiation apparatus installation table 10 is performed by first placing an operator of the measuring rod 5 on the center of the bottom surface of the shaft after an operator in the vertical shaft places the laser irradiation apparatus installation table 10 at the center position. Abut on the pin 3. Here, a part of one end of the measuring rod 5 is accommodated in the accommodating hole 13 a, thereby preventing the one end side of the measuring rod 5 from interfering with the installation base body other than the reference pin 3. Next, the worker on the ground informs the worker in the shaft that the position of the ground reference point is the scale position on the other end side of the measuring rod 5. And when the scale position of the measuring rod 5 is larger than the pipe bottom height, the operator in the shaft has support legs 2, 2.・ Rotate in the direction that lengthens, and adjust so that the scale position of the measuring rod 5 matches the tube bottom height. Further, when the scale position of the measuring rod 5 is smaller than the height of the bottom of the tube, the support legs 2, 2... Formed by the four bolts of the laser irradiation apparatus installation base 10 are turned in the direction of shortening. It adjusts and it adjusts so that the scale position of the measuring rod 5 and the pipe rod bottom height may correspond. As described above, the upper surfaces of the reinforcing plates 6 and 6 of the laser irradiation apparatus installation base 10 are perpendicular to an imaginary straight line that coincides with the longitudinal direction of the four support legs 2. By installing a level on the upper surface of the reinforcing plates 6 and 6 and adjusting the lengths of the four support legs 2,. can do.
図６は、本発明に係るレーザ照射装置設置台にレーザ照射装置を設置した状態を示す切断面図である。図６に示すように、レーザ照射装置７は、着脱可能な支持脚７ａ、７ａと、レーザ光線照射部７ｂとを有している。そして、着脱可能な支持脚７ａ、７ａの長さは、設置する配管の内径に対応して予め決められている。即ち、レーザ照射装置７を対応する配管の内部に直接載置した場合には、レーザ光線照射部７ｂから照射されるレーザ光線が配管の中心軸線と一致するように着脱可能な支持脚７ａ、７ａの寸法が設定されている。尚、下水道管等の埋設工事に使用される為の市販されているレーザー照射装置は、通常、上記の構成を備えている。
FIG. 6 is a sectional view showing a state in which the laser irradiation apparatus is installed on the laser irradiation apparatus installation base according to the present invention. As shown in FIG. 6, the laser irradiation device 7 has detachable support legs 7a and 7a and a laser beam irradiation unit 7b. The lengths of the detachable support legs 7a and 7a are determined in advance corresponding to the inner diameter of the pipe to be installed. That is, when the laser irradiation device 7 is directly placed inside the corresponding pipe, the support legs 7a and 7a are detachable so that the laser beam irradiated from the laser beam irradiation unit 7b coincides with the central axis of the pipe. The dimensions are set. In addition, the commercially available laser irradiation apparatus for using for burial work, such as a sewer pipe, is normally equipped with said structure.
上述のようにレーザ照射装置７が構成されているため、レーザ照射装置設置台１０の略円弧状のレーザ照射装置設置面１２にレーザ照射装置７を載置することにより、レーザ光線照射部７ｂから照射されるレーザ光線が、立坑から横方向に延長施工された配管の中心軸線と一致するようになる。即ち、前述したように、レーザ照射装置設置台１０の略円弧状のレーザ照射装置設置面１２は、略円弧状のレーザ照射装置設置面１２を含む仮想円筒４の内径と、設置される配管の内径とが略等しくなるように形成されていることから、着脱可能な支持脚７ａ、７ａの長さが設置する配管の内径に対応して予め決められているレーザ照射装置７を略円弧状のレーザ照射装置設置面１２に載置するだけで、レーザ光線照射部７ｂから照射されるレーザ光線が、設置された配管の中心軸線と一致するようになるのである。

That is, as described above, the laser irradiation device installation surface 12 of the laser irradiation device installation base 10 has the inner diameter of the virtual cylinder 4 including the substantially arc-shaped laser irradiation device installation surface 12 and the piping to be installed. Since the inner diameter is formed to be substantially equal, the length of the detachable support legs 7a and 7a is determined in accordance with the inner diameter of the pipe to be installed. The laser beam irradiated from the laser beam irradiation unit 7b only coincides with the central axis of the installed pipe simply by being placed on the laser irradiation device installation surface 12.
尚、レーザ光線の上下方向の傾斜角度の位置決めは、レーザ照射装置７に予め傾斜角度を入力しておくことによって、自動的に位置決めがなされる。また、レーザ光線の左右方向の位置決めは、設置しようとする前方の配管上方に位置する地上の基準位置から垂直に糸を垂らし、この糸にレーザ光線を当てることによって左右方向の位置決めがなされる。
The positioning of the tilt angle in the vertical direction of the laser beam is automatically performed by inputting the tilt angle to the laser irradiation device 7 in advance. Further, the laser beam is positioned in the left-right direction by hanging a thread vertically from a reference position on the ground located above the front pipe to be installed and applying the laser beam to the thread.
通常、下水道管等の配管設置工事は１日で完了するものでは無く、数日かけて行うものであることから、高価なレーザ照射装置７は、盗難に合うのを防ぐため、毎日の工事終了時に作業者が持って帰るものである。本発明に係るレーザ照射装置設置台１０は、前述のように構成されていることから、翌日のレーザ照射装置７の設置作業は容易でありながら精度良く設置することができ、作業時間を短縮することができ、施工コストの低減を図ることができるものである。

On the other hand, a male screw is formed on the outer peripheral surface of the support bar body 8a, and one end of the support bar body 8a is screwed with the support bar receiver 21a.
また、支持棒本体８ａの他方の端部側の外周面に形成されている雄ネジに螺合するように、引張コイルばね８ｂが装着されており、この引張コイルばね８ｂの一方の先端が棒状の接触部８ｃとなって、立坑の内周壁９に当接している。このように構成することによって、振動等による外力がレーザ照射装置設置台２０に加わった場合でもレーザ照射装置設置台２０の横方向へのずれを防ぐことができる。
Further, a tension coil spring 8b is mounted so as to be screwed into a male screw formed on the outer peripheral surface on the other end side of the support bar body 8a, and one end of the tension coil spring 8b is a rod-like shape. The contact portion 8c is in contact with the inner peripheral wall 9 of the shaft. With such a configuration, even when an external force due to vibration or the like is applied to the laser irradiation apparatus installation base 20, it is possible to prevent the laser irradiation apparatus installation base 20 from shifting in the lateral direction.
