PERFORATED PIPE
To provide a simple configuration of a perforated pipe capable of realizing ground improvement construction with good construction properties while allowing filling materials and sediment to flow into the perforated pipe.SOLUTION: A perforated pipe 100 has a first perforated pipe 10 and a second perforated pipe 20 both hollow. The first perforated pipe 10 is provided with a female screwing portion 11 having a screw thread 12 in a hollow wall surface of an end, and is provided with a first discharge hole 13 communicating with the screw thread 12 in the female screwing portion 11. The second perforated pipe 20 is provided with a male screwing portion 21 having a screw thread 22 on an outer peripheral surface of an end, and is provided with a second discharge hole 23 communicating with the screw thread 22 at the male screw portion 21. The female screwing portion 11 and the male screwing portion 21 are screwed together, and the filling material is discharged from the hollow H to the outside of the pipe through the communicating second discharge hole 23, the screw threads 12, 22 and the first discharge hole 13.SELECTED DRAWING: Figure 2
【課題】間詰め材や土砂の有孔管内への流入を許容しながら、良好な施工性の地盤改良施工を実現できる、簡易な構成の有孔管を提供する。【解決手段】共に中空の第一有孔管１０と第二有孔管２０を有する有孔管１００であり、第一有孔管１０は、端部の中空の壁面に螺子切り１２のある雌螺合部１１を備え、雌螺合部１１において螺子切り１２に連通する第一吐出孔１３を備え、第二有孔管２０は、端部の外周面に螺子切り２２のある雄螺合部２１を備え、雄螺合部２１において螺子切り２２に連通する第二吐出孔２３を備え、雌螺合部１１と雄螺合部２１が螺合され、連通する第二吐出孔２３と螺子切り１２，２２と第一吐出孔１３を介して中空Ｈから管外へ充填材が吐出される。【選択図】図２
