UNDERGROUND DRAINAGE TOOL AND UNDERGROUND DRAINAGE STRUCTURE
To provide an underground drainage tool and an underground drainage structure capable of smoothly discharging groundwater without causing clogging due to particles such as earth and sand.SOLUTION: An underground drainage device 1 for discharging groundwater w permeating into the ground comprises a tubular member 2 formed in a hollow interior and inserted into the ground in an obliquely downward posture in the length direction, a water passage hole 4 which is formed through a pipe wall 2c of the pipe member 2 and whose lower edge appears when the pipe member 2 is in an obliquely downward posture, and a cover portion 5 that is provided on the pipe member 2 in the length direction of the pipe member 2 from the lower edge position of the water passage hole 4 so as to cover the water passage hole 4 with respect to the ground, and defining and forming an inlet 8 opening toward the ground between the lower edge and itself. The underground drainage device 1 is used for an underground drainage structure. The underground drainage device 1 is inserted into the ground with the inlet 8 and the pipe member 2 facing obliquely downward. The obliquely downward tip of the pipe member 2 is arranged to be exposed from the ground to the ground surface as an insertion end.SELECTED DRAWING: Figure 3
【課題】土砂などの粒分によって目詰まりが生じることがなく、地下水を円滑に排出することが可能な地中排水具及び地中排水構造を提供する。【解決手段】地中に浸透している地下水ｗを排出する地中排水具１は、内部中空に形成され、長さ方向に沿って斜め下向きの姿勢で地中に挿入される管材２と、管材２の管壁２ｃに貫通形成された穴形態であって、管材２が斜め下向きの姿勢で下縁が現れる通水孔４と、管材２に、地中に対して通水孔４を覆うように、通水孔４の下縁位置から管材２の長さ方向に沿って設けられると共に、下縁との間に、地中に向けて開口される流入口８を区画形成する覆い部５とを備えた。地中排水構造は、上記地中排水具１を用い、地中排水具１は、流入口８及び管材２が斜め下向きとなる姿勢で地中に挿入され、管材２の斜め下向き先端は、挿入終端として地中から地盤面に露出されるように配置される。【選択図】図３
