公告昭５７−２０９３４号）。2. Description of the Related Art In underground pipes, it is sometimes necessary to arrange pipes having a directional cross section in a predetermined cross section direction. For example, in a sewer pipe, a pipe having an oval cross section (an oval pipe) is piped with the longitudinal axis of the cross section directed vertically, so that the water depth is deepened, and the water flow is accelerated accordingly to remove dirt and solids. Known to reduce sedimentation,
In this case, it is necessary to bury the oval tube in the ground with the longitudinal direction of its cross section vertical. Therefore, as shown in FIGS. 4A and 4B, the present applicant attaches a tube support base B ′ having horizontal portions 21 ′ and 22 ′ at lower ends on both sides of an inverted U-shaped cross section 1 ′. The cross-section of the oval tube A 'is resiliently fitted to the tube A', connected to the previous tube being installed, and placed on the tube laying base surface E 'of the tube support B'. It has already been proposed to orient the long axis direction in the vertical direction (U.S. Pat. No. 5,783,849).

The longitudinal direction of the cross-section of the pipe A 'is directed in the vertical direction by contact with the base surface E'. Unless a strict flat-out of the pipe-laying base surface is performed, it is difficult to perform a high-precision pipe cross-sectional direction. Further, the fulcrums n, n are below the center of gravity G of the tube A ', and the supporting state is unstable.

It is necessary to bury the above-mentioned pipe support and the pipe part in the vicinity thereof in the embankment so as not to cause the problem. In addition, if it is found that a deviation has occurred in the pipe cross-section direction before backfilling the pipe, it is necessary to correct the inclination direction of the pipe cross-section in the already-filled pipe support base. However, in the above-described pipe support, the embankment must be removed until the pipe laying foundation surface appears, and the repair work is troublesome.

In this way, after vertical alignment of the pipe section in the long axis direction and alignment of the pipe core, the protective sand or the high quality soil described above is placed on the stabilizer of the pipe support base and on the side and upper portions of the pipe in the vicinity thereof. The tube is raised, and the fixed state of the tube is strengthened against the load when the next tube is connected. Thereafter, by repeating the above, the pipes are connected and arranged while performing vertical alignment in the longitudinal direction of the pipe cross section and pipe core alignment,
After the installation of all pipes, the trenches will be backfilled.

If it is found that the direction of the pipe section is misaligned and it becomes necessary to correct the direction of the pipe section at a certain pipe support, the embankment on the pipe support to be corrected should be placed on the stabilizer plate. By removing one of the stabilizers and pressing either one of the left and right stabilizers according to the direction of the shift, the correction can be easily performed.
