MANHOLE FOR PIPE CONDUIT, PIPE CONDUIT CONNECTION STRUCTURE OF END PART OF PIPE CONDUIT, JOINT ELEMENTS FOR PIPE CONDUIT, AND PIPE CONDUIT CONSTRUCTION METHOD
To provide a pipe conduit connection structure, a pipe conduit joint element, and a pipe conduit construction method that have water-stop properties and durability in order to solve a technical problem that may cause a difference in crimping between a connection part and a coupling member, and a technical problem that it is difficult to prevent water from seeping in from the connection part because it is not possible to integrate a pipe opening and the coupling member with the same material.SOLUTION: The present invention relates to a manhole, a pipe conduit connection structure of an end part of the pipe conduit, a joint element for the pipe conduit, and a pipe conduit construction method. The pipe conduit connection structure comprises: an injection material layer covering a wall surface of the manhole; a liner covering a surface of the injection material layer; a joint element with an embedded heating wire; and an input terminal of an external power supply, wherein an inner surface of the pipe conduit and an inner wall surface of the joint element have a multilayer structure including, from the outside, an outer film, an intermediate layer, and an inner film of thermoplastic resin, and one surface of the intermediate layer is covered with the outer film, and the other surface of the intermediate layer is covered with the inner film.SELECTED DRAWING: Figure 1
【課題】結合部と連結部材の圧着に差異が生じ得るという技術的課題と、管口と連結部材を同一素材で一体化することができないため、結合部からの浸入水を防ぐことが難しいという技術的課題を解決するための、止水性及び耐久性を兼ね備えた管渠のための管渠結合構造、管渠継手要素と管渠工法の提供。【解決手段】人孔と、管渠の端部の管渠結合構造であって、人孔の壁面を被覆する注入材層と、当該注入材層の表面を覆うライナと、継手要素であって、電熱線が埋設された前記継手要素と、外部電源の入力端子と、前記管渠の内表面及び継手要素の内壁面に、外側から、熱可塑性樹脂のアウターフィルム、中間層及びインナーフィルムを含む多層構造が構成され、前記中間層の一方の面がアウターフィルムによって被覆され、前記中間層の他方の面によってインナーフィルムが被覆する管渠結合構造、管渠用継手要素と管渠工法。【選択図】 図１
