本考案は、下水道管等の埋設に当り、開削溝中
に泥水を満たしその中に管体を沈設する場合に使
用する管体埋設装置に関する。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a pipe burying device used when burying a sewer pipe or the like by filling an cut trench with muddy water and sinking the pipe therein.
近年、下水道管等の管体を、泥水で満した開削
溝中に沈設させ、連設する方法が一部実用化され
ている。
In recent years, some methods have been put into practical use in which pipe bodies, such as sewer pipes, are sunk into cut-and-cover trenches filled with muddy water and installed in series.
この沈設には、従来、各管体ごと沈設するよう
にしている。しかし、これではその都度の沈設作
業となり、施工性がきわめて悪い。しかも、先の
沈設管体に次の沈設管体を泥水中で連結すること
は、泥水中であるため、管体が目視できず、著し
く困難である。 Conventionally, each pipe body has been sunk in this process. However, this requires submersion work each time, and the workability is extremely poor. Moreover, it is extremely difficult to connect the next submerged pipe to the previous submerged pipe in muddy water because the pipe cannot be visually observed.
さらに、この種の埋設にあたつては、管体群の
直線性が要求されるが、個別に沈設する場合に
は、その作業がきわめて難しい。 Furthermore, this type of burying requires straightness of the tube group, which is extremely difficult to do when burying the tubes individually.

れがために施工性の低下を招く。 On the other hand, although a concrete pipe or the like may be used as the pipe body, a lightweight pipe body such as a vinyl chloride pipe may also be used. This type of lightweight pipe body often has difficulty sinking under its own weight due to muddy water. Therefore, in order to increase the sinking force, steel materials such as H-shaped steel or channel steel are attached to the lower part of the pipe body, or to both the upper and lower parts. In this case, the steel material is placed along the tube and secured by winding a steel band around key points. However, in order to prevent the steel material from easily coming off the pipe, the band must be tightened strongly, but if the band is tightened too tightly, the pipe may bend or the cross section may become deformed if the pipe is made of vinyl chloride. . Furthermore, due to the deformation of the tube body,
Sometimes the tube cannot be set in the desired position. Therefore, installation of steel materials requires careful attention, which leads to a decrease in workability.

The present invention solves the above-mentioned conventional problems, significantly improves workability when burying lightweight pipes, facilitates straight burying, and provides upper support even for lightweight pipes. It is an object of the present invention to provide a device for burying a pipe body that is easy to bury due to the presence of the member and the lower support member.

から外して撤去する。他の部材は埋殺しとなる。 Such a tube embedding device is used as follows. That is, as shown in FIGS. 4 and 5, first, a trench 12 is excavated while being filled with slurry such as bentonite slurry 11. 13 is a guide wall. Next, as shown in FIG. 6, a predetermined number of unit tubes are arranged in series on the ground, and an annular holder 2 and support members 3, 4 are attached to each unit tube. This attachment is carried out by first covering the tubular body 1 with the ring pieces 21 and 22, arranging the supporting members 3 and 4, and assembling them with the connecting bolts 5 and 7. Finally, the suspension member 10 is screwed onto the suspension receptacle 9. The tube group of a predetermined length obtained in this way is then suspended via each suspension member 10 by an interlocking type electric chain block 15 etc. provided on the pedestal 14, as shown in FIG. It is sunk into the trench 12. after that,
As shown in Figure 8, use a leveling rod 16, etc. to confirm the sinking depth (position), and when it reaches the correct depth,
The upper part of the hanging member 10 is fixed to a support stand 17 made of H-shaped steel or the like, and the muddy water 11 is waited for to solidify. Note that illustration of the annular holder 2 and supporting members 3 and 4 is omitted in FIG. Once muddy water 11 has solidified,
Rotate each suspension member 10 in the opposite direction, and
Remove and remove. Other parts will be buried.

場合、一方のフランジ部相互を枢着し、他方のフ
ランジ相互を拡閉させるようにしてもよい。 By the way, although the annular holder in the above example is of a split type, it may be an integral annular body if necessary. In this case, it is attached by fitting in relatively from the end of the tube. Moreover, when using a split type, one flange part may be pivotally connected to each other, and the other flange parts may be made to expand and close each other.

Bolt connection at the flange part can be easily and firmly fixed. Note that the lower support member 4 can be omitted when an integral annular holder or the like is used. As the support members 3 and 4, in addition to channel steel, H-beam steel or other appropriately shaped members without deflection can be used.
以上の通り、本考案によれば、複数の管体を同

As described above, according to the present invention, multiple pipe bodies are sunk at the same time, which improves work efficiency.
In addition, since each pipe body is connected on the ground, construction efficiency is improved compared to connecting them in muddy water.

できる。 In addition, we provided a support member made of steel that also functions as a sinking force increasing member, so if it is a lightweight pipe, it is easy to sink it while filling the pipe with water, while if it is a heavy pipe, it can be placed inside the pipe. There is no need to fill it with water and then sink it, making the installation process easier. Furthermore, since the supporting member does not bend, when the whole is lifted up, there is no bending deformation even if the tube is made of vinyl chloride or the like.
Furthermore, since the annular holder attached to each target tube is attached to a support member provided along the group of connected target tubes, the presence of the support member allows the connected tubes to be moved vertically and horizontally. This makes it possible to level the tube group and prevent it from swinging from side to side, which has been extremely difficult in the past, in an extremely simple and stable manner.
かくして、全体として沈設作業が円滑となり、
正確な沈設が可能となる利点がもたらされる。 In this way, the entire sinking work becomes smooth, and
This provides the advantage of allowing accurate placement.
