IMPERVIOUS STRUCTURE, PIPE MEMBER UNIT USED IN IMPERVIOUS STRUCTURE, AND CONSTRUCTION METHOD OF IMPERVIOUS STRUCTURE
To provide: an impervious structure capable of enabling work at a construction site to be performed easily while increasing the reliability of maintaining water-tightness at the joint portion between a synthetic resin plate and a pipe member installed penetrating the inside and outside of a recess, and at the joint portion between the synthetic resin plate and an impervious sheet; a pipe member unit used in the impervious structure; and a construction method of the impervious structure.SOLUTION: An impervious structure is configured such that: a recess D formed in the ground is laid with an impervious layer comprising an impervious sheet 1 and a protective material 2, as well as, installed with a pipe member 3 penetrating the inside and outside of the recess; the pipe member 3 is integrally joined respectively with a first synthetic resin plate 41, through which the pipe member 3 penetrates, and a second synthetic resin plate 42 having a smaller outer peripheral shape than that of the first synthetic resin plate 41; and the first synthetic resin plate 41 is joined to a lower layer waterproof sheet 11, and the second synthetic resin plate 42 is joined to an upper layer waterproof sheet 12.SELECTED DRAWING: Figure 1
【課題】工事現場での作業を簡易にできるようにしながら、合成樹脂板と凹部の内外を貫通して設置される管部材との接合部分及び合成樹脂板と遮水シートの接合部分の水密性の維持の信頼性を高めることができる遮水構造、遮水構造に用いられる管部材ユニット及び遮水構造の構築工法を提供すること。【解決手段】地面に形成された凹部Ｄに、遮水シート１と保護材２とを備えた遮水層を敷設するとともに、凹部Ｄの内外を貫通する管部材３を設置するようにし、管部材３には、管部材３が貫通する、第一の合成樹脂板４１と、第一の合成樹脂板４１より外周形状が小さな第二の合成樹脂板４２とが、それぞれ一体に接合され、第一の合成樹脂板４１と下層遮水シート１１が接合され、第二の合成樹脂板４２と上層遮水シート１２が接合される。【選択図】図１
