場合には、該基礎の砂も流動する為、管４の沈下
が生じるという欠点があつた。 If the ground for laying water pipes, etc. is soft ground, as shown in Figure 1, after driving sheet piles 2, 2 into the ground 1, excavate the space between the two sheet piles to a predetermined depth and lay the pipes. A path 3 is formed, and a foundation 5 is laid in the pipe installation path 3 to prevent the pipe 4 from sinking, and the pipe 4 is laid. This foundation 5 is a concrete foundation if the pipe 4 is a concrete pipe, or a sand foundation if it is a synthetic resin pipe. Next, after filling the pipe laying path 3 with sand 6, the sheet piles 2, 2 are pulled out and embanked. When the sheet piles 2, 2 are pulled out, the sand 4 flows toward the space equal to the thickness of the sheet piles 2, 2 created after the pulling out. Therefore, according to this conventional construction method, the foundation 5 is
If the foundation is made of concrete, the pipe 4 will not sink due to the flow of sand, but if the foundation is made of sand, the sand of the foundation will also flow, causing the pipe 4 to sink. Ta.

を提供することを目的とする。 This invention was made in order to eliminate the above-mentioned conventional drawbacks, and by erecting a floating protection wall that extends along both sides of the pipe by driving the piles deeply, the sinking of the pipe after the sheet pile is pulled out is prevented. The purpose of the present invention is to provide a pipe installation method that can prevent the above problems and improve the quality of the pipe line compared to conventional methods.
以下、この発明の一実施例を図について説明す
る。 An embodiment of the present invention will be described below with reference to the drawings.

抜き、盛土する。 In FIGS. 2 and 3, 7 and 8 are flow protection fences, which are installed on both sides of the synthetic resin pipe 4.
It extends along the channel of the tube 4. Flowing protection fence 7
After finishing the excavation of pipe laying route 3, piles 9, 9, 9 were installed.
... into the pipe installation path 3 deeper than the penetration depth of the sheet piles 2, 2, and install flow protection plates 10, 1 between the piles.
It is constructed by connecting 0, 10.... Flowing protection fence 8
The pipes are placed in the pipe installation path 3 in the same way, and then the sand foundation 5 is laid at the bottom of the pipe installation path 3, the pipe 4 is laid, the pipe installation path 3 is filled with sand 6, and then the sheet piles 2, 2 are Pull it out and fill it up.
なお、流動防護塀７の設置は、管４の後であつ
ても矢板引き抜き前であれば良い。 Note that the flow protection wall 7 may be installed after the pipe 4 or before the sheet pile is pulled out.

ず、矢板引き抜き後の管４の沈下が防がれる。 In this construction method, when the sheet piles 2, 2 are pulled out, sand flows toward the space after the sheet piles are pulled out in the upper and outer parts of the flow protection walls 7, 8, but the piles 9, 9, 9... If it is driven deeper than the penetration depth of the sheet piles 2 and 2, there is no risk that the flow protection walls 7 and 8 will tilt even if sand flow occurs, and the sand 6 and the sand between the pipe 4 and the flow protection walls 7 and 8 will be removed. Since the foundation 5 is restrained by the flow protection walls 7 and 8, it does not flow, and the pipe 4 is prevented from sinking after the sheet pile is pulled out.

大きく傾斜しない深さであればよい。 Note that it is sufficient for the flow protection walls 10, 10, 10, . Also, the driving depth of the piles 9, 9, 9... does not need to be deeper than the driving depth of the sheet piles 2, 2, and it is sufficient as long as the floating protection walls 7, 8 do not tilt significantly due to the sheet piles being pulled out. .

めることができる。 As described above, according to the present invention, flow protection walls extending along the pipe are erected on both sides of the pipe to be laid in the pipe laying path made on soft ground by excavating between the sheet piles. By driving the piles deeply, it is possible to prevent the pipe from sinking after the sheet pile is pulled out, so the quality of the pipe can be improved compared to the conventional method by a simple means.
