後の堆砂によりパイプは埋設状態になる。In the invention of this application as described above, when burying a pipe with an opening, the sediment of the dam lake is dredged in a groove-like manner, or when a water level is lowered, a river channel is used and the eroded and excavated groove is used. The pipe with the opening is laid at the bottom of the groove. For newly constructed dams, pipes with openings will be laid at the bottom of the lake. In either case, the subsequent sedimentation causes the pipe to be buried.
【００１１】このパイプの上流開放端または上流部の水
中にある開口部は、堆砂で埋まることがない位置で、水
中に維持されることが必要である。[0011] The upstream open end of the pipe or the opening in the water at the upstream portion needs to be maintained in the water at a position where it is not filled with sediment.

めるが、パイプ内が周囲の静流体圧に比べて低圧となる
ために、開放端または開口部からパイプ周囲の堆砂を流
体とともに吸い込み排出する。By flowing flowing water through the pipe, the fluid starts to be sucked from the upstream open end or the opening in the upstream water. However, since the pressure in the pipe is lower than the surrounding static fluid pressure, the open end is reduced. Alternatively, the sediment around the pipe is sucked and discharged together with the fluid from the opening.
【００１３】この排出はパイプの開口部に沿って順次発

排出する。This discharge occurs sequentially along the opening of the pipe and discharges a wide range of deposits corresponding to the length of the pipe with the opening.

The flow rate is reduced, the suction power is reduced, and as a result dilution occurs. Conversely, when the concentration is low, the flow rate is high and the suction force is large, so that the concentration increases accordingly. Therefore, without using any control device, the suction force is automatically adjusted over the entire length of the pipeline with the opening by locating the opening in the water at the upstream end or the upstream in the water. Is realized.

It is also possible to bend into a J-shape and use a hole provided in the bent portion to excavate a groove or a recess from the upper portion of the deposition surface. At this time, the tip of the pipe can be moved by a boat or barge from the surface of the water, by a remote moving vehicle underwater, or manually by a diver.
