CONSTRUCTION METHOD OF MANHOLE WITH GUIDE PASSAGE, AND VERTICAL PIPE WITH GUIDE PASSAGE
To provide a construction method of a manhole with a guide passage capable of exhibiting appropriate damping performance without causing turbulent flow of flowing down sewage, and allowing direct reception of soil pressure, and allowing direct setting into a temporary vertical shaft even when a concrete manhole is not available.SOLUTION: A construction method of a manhole with a guide passage includes: a step 1 of preparing a vertical pipe 10 with a guide passage having a linear vertical pipe body 11, a spiral guide passage 14 spirally provided along a shaft core O of the vertical pipe body 11 and allowing spiral flow-down of inflow fluid, and branch pipes 12 connected to openings 16 formed to one end side and the other end side of the vertical pipe body 11; a step 2 of forming an earth retaining wall 51 to a vertical hole 50; and a step 3 of installing the vertical pipe 10 with the guide passage inside the earth retaining wall 51.SELECTED DRAWING: Figure 1
【課題】流下する下水の流れに乱れを生じさせることなく、適切な減衰性能を発揮させることを可能にするとともに、直接、土圧を受け持つことを可能にし、コンクリート製のマンホールが無くても、仮設の立坑に直接、設置することを可能にする。【解決手段】案内路付きマンホールの施工方法は、直管状の縦管本体１１と、縦管本体１１の軸芯Ｏに沿って螺旋状に設けられ、流入した流体を螺旋状に流下させる螺旋案内路１４と、縦管本体１１の一端側と他端側に形成された開口部１６に接続する枝管１２と、を備える案内路付き縦管１０を準備する工程１と、竪穴５０に土留め壁５１を形成する工程２と、土留め壁５１の内側に案内路付き縦管１０を設置する工程３と、を含む。【選択図】図１
