CONSTRUCTION METHOD FOR TEMPORARY DRAINAGE DITCH
To provide a construction method for a temporary drainage ditch which is easy to construct and remove and can stably drain rainwater flowing through the temporary drainage ditch even during heavy rain.SOLUTION: A construction method for a temporary drainage ditch includes a step of excavating the ground to form a ditch, covering the surface of the ditch with a sheet material, and fixing the sheet material to the ground by a fixing member to form a temporary drainage ditch. The sheet material comprises a nonwoven fabric and a mesh-like reinforcing net disposed on the surface of the nonwoven fabric, and the nonwoven fabric has a basis weight of 30 to 60 g/m2.SELECTED DRAWING: Figure 2
【課題】施工および撤去が容易であり、強雨の際にも仮排水溝を流れる雨水を安定して排水することができる仮排水溝の施工方法を提供すること。【解決手段】仮排水溝の施工方法であって、地面を掘削して溝部を形成し、前記溝部の表面をシート材で被覆し、固定部材によって前記シート材を地面に固定して、仮排水溝を形成する工程を含み、前記シート材は、不織布と、前記不織布の表面に配設された網目状の補強ネットとを備え、前記不織布の目付量が３０～６０ｇ／ｍ２である。【選択図】図２
