【０００１】
【発明の属する技術分野】
本発明は、工場や家庭の汚水桝や雨水桝から地中へと連設された排水取付管の補修方法及び該方法に用いる補修装置に関するものであり、より詳しくは、工場や宅内に設置された汚水桝や雨水桝から下水道本管に接続された既設の埋設排水取付管に亀裂や破損が生じた際に、掘り起こすことなく非開削で取付管内面に補修材層を張設して取付管を更生する技術に関する。
【０００２】
【従来の技術】
〔特許文献１〕特開２００１−３０３５７号公報
各家庭内には宅内桝、即ち汚水桝が設置してあり、該汚水桝から道路下面の下水道本管までは地中に埋設した排水取付管で連通してあるが、取付管は経年変化による老朽化や外的荷重、或いは地震等によって破損や継目の開離が生じ、これに伴う地下水や土砂の流入、或いは汚水の地中への流出等が生じるため、取付管の修繕改築が必要となる。
【０００３】
従来の、宅内桝から下水道本管へ連結した排水取付管の最も一般的な修繕改築方法は、取付管に単にひび割れ等で漏水を生じている程度の場合でも、埋設されている取付管を掘り出して既設取付管を撤去し、新たに取付管を設置埋設する開削工法である。
しかし、市街地での該開削工法では、道路を掘り返すため、交通事情に悪影響を及ぼす点、近隣住民への影響等、住環境問題面から好ましくない。
従って、近年は、このような開削工法に代る非開削工法が開発され、実用化されている。
【０００４】
非開削工法としては、ＩＰＣ（Ｉｎｖｅｒｓｉｏｎ Ｃｈｅｍｉｃａｌ Ｐｉｐｅ）ブリース工法やＬＩＰ（Ｌａｔｅｒａｌ ｉｎ Ｐｉｐｅ）工法の反転工法があり、ＩＰＣブリース工法は、合成樹脂含浸補修材の反転挿入を本管側から取付管側へ圧縮空気によって行い、温水を補修材内へ充填注入して補修材を硬化させるものであり、ＬＩＰ工法は、宅内の汚水桝側で補修材の端部を取付け、圧縮空気によって既設取付管内に補修材を反転挿入し、補修材を硬化後、本管内及び汚水桝内に突出した部分を切断除去するものである。
【０００５】
本発明者は、ＩＰＣブリース工法やＬＩＰ工法とは全く異なる画期的な排水取付管補修の新規工法を、特願２０００−３０９１５８号（特開２００１−３０３５７号）として提案した。
即ち、該提案発明は、図１６に示すものであって、硬化性合成樹脂を含浸させた補修材５を反転ゴム４と接続紐１２で連係させて共に反転ガイド２内に装着し、高圧流体Ａを供給しながら反転ロープ１１によって反転ゴム４と補修材５とを共に排水取付管Ｐ１内に反転挿入し、図１６（Ｂ）の如く、補修材５の布材５１で取付管Ｐ１の内面を被覆圧接した状態で補修材の布材５１を硬化処理し、図１６（Ｃ）の如く、排水取付管Ｐ１の内周全面を布材５１の硬化管層で更生補修するものである。
【０００６】
【発明が解決しようとする課題】
図１６の画期的な排水取付管補修方法は、補修材５を反転ゴム４が圧接した状態で補修材を硬化処理するため、布材５１によって形成される更生管層の内面は、流水に支障を生ずるような皺は発生せず平滑面となり、また、反転ゴム４の反転挿入可能な形態の取付管全てに補修施工が可能となるもので、作業面からも、補修更生管の品質面からも、極めて優れたものである。
【０００７】
しかし、図１６（Ｂ），（Ｃ）に示す如く、取付管Ｐ１の内周面に対する布材５１による新規更生管層の形成であるため、排水取付管Ｐ１の管口ＰＥでは、取付管Ｐ１内から本管Ｐ０内に至るクラックＫ１や、取付管Ｐ１と本管Ｐ０との連結部の隙間Ｋ２の補修は出来ない。
そして、クラックＫ１や隙間Ｋ２の存在は、取付管周囲の地層からの雨水や地下水、土砂等の本管Ｐ０内への流入を生ずるため、必要に応じて、別途本管Ｐ０内側から別の補修材で、取付管口ＰＥ周囲を補修する必要がある。
本発明は、該図１６の補修方法を画期的に改善するものであり、特願２０００−３０９１５８号（特開２００１−３０３５７号）の発明の実施に際し、１本の補修布材５１によって取付管内周面の更生補修と同時に、取付管口ＰＥの周囲をも補修可能とするものである。
【０００８】
【課題を解決するための手段、及び作用】
本願の補修方法の発明は、例えば図１、図２に示す如く、合成樹脂を含浸させた筒状の補修布材５１を含む補修材５と、筒状の反転ゴム４とを連係させて反転ガイド２内に装着し、高圧流体Ａの反転ゴム４への作用によって、反転ゴム４及び補修材５を反転ガイド２から排水取付管Ｐ１内へ、補修材５が反転ゴム４の外側になるように反転挿入して補修布材先端５１Ｅ（図１３）を本管Ｐ０内に突出し、反転ゴム４を本管Ｐ０内に配置した支持プレート９４に当接した状態で反転ゴム４の反転作用を停止し、次いで、反転ゴム４内の高圧流体Ａの圧力のみを増加し、反転ゴム４の先端で支持プレート９４と管口ＰＥ間で変形した膨出バルーン４Ｂを形成し、補修材５を取付管Ｐ１内周面に圧接すると共に、補修布材先端５１Ｅを取付管Ｐ１の管口ＰＥを覆う鍔Ｒ形態に拡開圧接した状態で含浸合成樹脂を硬化し、補修布材５１の硬化後に反転ゴム４を引抜き、反転ガイド２を補修材５から切離すものである。
【０００９】
尚、補修布材としては、長さ方向及び径方向に自在に変形する従来の補修材が適用出来、布材先端５１Ｅが鍔Ｒ状に拡開変形可能な編地組織、又は拡開用切れ目を入れた布の重層形態としても使用可能であるが、典型的には、合成樹脂の含浸保持能、及び変形自在性を備えている横メリヤスパイル組織の筒状編布である。
また、膨出バルーン４Ｂは、図１に示す如く、補修布材先端５１Ｅを管口ＰＥの外側に鍔Ｒ形態に押圧すれば良く、支持プレート９４による膨出バルーン４Ｂの変形形態も補修布材先端５１Ｅの寸法に応じて決定すれば良い。
また、筒状の補修材５の筒状の反転ゴム４との連係は、反転ゴム４の反転挿入時に補修材５が共に反転挿入されれば良く、補修材の基端５Ｅが反転ガイドに保持され、補修布材先端５１Ｅが反転ゴム４の内側に引込まれていれば良い。
また、支持プレート９４は、反転ゴム４の頭部の膨出を支持して膨出バルーン４Ｂが補修布材先端５１Ｅを管口ＰＥに押圧するように膨出バルーン４Ｂを規制すれば良く、手作業で本管Ｐ０内に配置固定した板材でも、或いは本管Ｐ０内で移動可能な車台に取付けた板材でも良い。
【００１０】
尚、ここで言う、「取付管Ｐ１」は、宅内桝から下水道本管へ連結した取付管をはじめ、家庭や工場の雨水桝から下水道本管に連結した排水取付管や、工場の廃液処理桝からの排水用取付管等、地表に設置した水溜め（桝）から地下の排水本管Ｐ０（下水道本管）に連結した地中埋設の取付管を広く意味するものであり、「反転ゴム」は、合成ゴム、天然ゴム等、ゴム弾性を有するシート材等、膨出バルーン４Ｂの形成出来る材料を広く意味するものであり、「合成樹脂」は、光硬化、熱硬化、自然硬化（経時硬化）する合成樹脂を広く意味するものであり、「流体」は、空気、加熱又は常温の水、ガス等を意味するものである。
【００１１】
従って、補修材５は、高圧流体作用を受ける反転ゴム４と共に反転ガイド２から取付管Ｐ１内へ連係して一緒に反転挿入されるため、反転ゴム４の反転挿入可能な場所は全て補修材の反転挿入も可能であり、取付管Ｐ１が弯曲、或いは屈曲していても補修材の取付管Ｐ１内への挿入配置は可能である。
更に、寸法安定性に乏しい補修材５が反転ゴムの外側へ反転されて行くため、補修材の反転挿入部が反転ゴム４の膨張加圧力で、順次取付管Ｐ１内周面に押圧されて行き、取付管Ｐ１の屈曲部での補修材の皺の発生も最小限となり、例え少し発生する皺も反転ゴム４の加圧によって補修材５の反転ゴム４と当接した内周面は流路として支障のない程度の平滑面となる。
【００１２】
更に、補修材５の反転挿入作業は、反転ガイド２先端を取付管Ｐ１の入口部に近接配置して実施出来るため、補修材５の必要長は補修対象取付管Ｐ１の長さに対応設定出来、従来の反転硬化工法（ＬＩＰ工法）の如き補修材の先端部と基部での長寸の切断廃棄部分が生じなく、補修材及び合成樹脂等の材料の使用が合理化出来る。
更に、補修材５の反転挿入のための準備作業が補修対象取付管Ｐ１から離れた地上で実施可能であるため、施工準備作業が合理化出来る。
【００１３】
しかも、補修布材先端５１Ｅを本管Ｐ０内に突出して、反転ゴム４の先端を支持プレート９４に当接した状態で加圧膨張させるため、膨出バルーン４Ｂは、比較的小径のバルーンが横方向拡開した偏平形態となり、補修布材先端５１Ｅを管口ＰＥに鍔Ｒの形態で当接出来、鍔Ｒの形成が、反転ゴムの負荷を最少限に抑制して合理的に実施出来る。
そして、鍔Ｒは取付管Ｐ１の管口ＰＥに当接硬化するため、図１６に示す如き取付管Ｐ１から本管Ｐ０へと連なるクラックＫ１や、取付管Ｐ１と本管Ｐ０との取付部の隙間Ｋ２を閉止補修出来、本発明の補修は、反転ゴム４の反転作用によって、取付管内周面の更生補修施工に加え、従来では別施工でしか実施出来なかった取付管口ＰＥの補修も同時に施工出来る。
従って、本発明によれば、取付管Ｐ１の内周全面と、取付管Ｐ１の本管Ｐ０への取付部の管口ＰＥとが、同時に補修布材５１によって更生補修出来、排水取付管の画期的な補修手段の提供が可能となる。
【００１４】
また、本願補修方法の発明にあっては、反転ゴム４が支持プレート９４に当接した状態で反転ゴム４の反転作用を停止し、次いで、反転ゴム４内の高圧流体Ａの圧力のみを増加し、反転ゴム４の先端を支持プレート９４と管口ＰＥ間で偏平に変形した膨出バルーン４Ｂとする。
支持プレート９４は、図１３に示す如く、本管Ｐ０内で移動可能であり、補修布材先端５１Ｅが本管Ｐ０内に露出した段階で反転作業を停止するため、支持プレート９４の取付管口ＰＥへの配置が容易である。
そして、反転ゴム４は、先端の突出長を支持プレート９４への当接で固定するため、反転ゴム４の膨出負荷を鍔Ｒの形成に必要な程度に抑制出来る。
【００１５】
従って、本発明によれば、反転ゴム４が支持プレート９４に当接した状態で反転ゴムの反転作用を停止するため、反転ゴム４の先端の突出量を最少限に抑制出来、支持プレート９４による規制された膨出バルーン４Ｂの偏平形態変形によって、補修布材先端５１Ｅへの合理的な当接押圧が可能となり、反転ゴム４の膨出負荷の規制された比較的小さな偏平形態の膨出バルーン４Ｂによって、補修布材先端５１Ｅでの管口ＰＥの被覆に必要な鍔Ｒの形成が可能となる。
【００１６】
また、本願補修方法の発明にあっては、支持プレート９４を取付管Ｐ１の管口ＰＥに略平行に配置するのが好ましい。
尚、「管口ＰＥに略平行」の意味は、管口ＰＥの仮想平面と支持プレート９４が略平行を意味し、取付管口ＰＥが地面に対して傾斜して本管Ｐ０に開口しておれば、支持プレート９４も傾斜配置することを意味する。
従って、支持プレート９４を管口ＰＥに略平行配置するため、反転ゴム４の先端の膨出バルーン４Ｂの支持プレート９４による偏平化変形は管口ＰＥに対して均斉となり、比較的小さな膨出バルーン４Ｂであっても布材先端５１Ｅによる均斉な鍔Ｒの形成が合理的に実施出来、強度劣下及び損傷の生じ易い反転ゴム４の耐久性が向上する。
【００１７】
また、補修材５の基端５Ｅを反転ガイド２の先端２Ｔの外周に締着し、補修材先端５Ｔを反転ゴム４内に引込んで接続紐１２によって反転ゴム先端４Ｔと接続し、反転機１の巻芯１３から巻戻しされる反転ロープ１１に反転ゴム先端４Ｔを接続し、反転ゴム４の反転ガイド２からの排水取付管Ｐ１内への反転延出によって補修材５を反転ゴム４の外側へ反転延出するのが好ましい。
この場合、接続紐１２と補修材先端５Ｔとの接続は、反転ゴム４の引抜き作用により解除される程度の弱い仮固定で実施出来る。
【００１８】
従って、補修材基端５Ｅが反転ガイド２の先端２Ｔの外周に締着されているため、補修材５の反転ガイド先端２Ｔからの反転作用がスムーズとなり、反転ガイド先端２Ｔを取付管Ｐ１の口部に近接して施工することにより補修材５の補修後の廃棄長を最少限に節約出来、使用材料の合理化が可能となる。
更に、補修材先端５Ｔと反転ゴム先端４Ｔ間には接続紐１２が存在するため、補修材５の反転ゴム４内への挿入作業は、接続紐１２を引張ることによって容易となり、反転ガイド２内への補修材５及び反転ゴム４の装着作業も容易となる。そして、反転ゴム４は、補修材５全長を取付管Ｐ１内に反転挿入した後も補修材先端５Ｔを越えて反転挿入出来、反転ゴム先端の膨出バルーン４Ｂの選択形成も可能となり、補修材５の鍔Ｒ部分を含む全長を覆って加圧することにより、補修材５の取付管Ｐ１内周面全長と取付管口ＰＥの鍔Ｒに対する押圧硬化が均斉に実施出来る。
【００１９】
また、補修材５が、少なくとも合成樹脂の含浸した布材５１と、外側のシート５２と、内側のシート５３の遊離重層形態の３層を含んでいるのが好ましい。
布材５１、外側シート５２、内側シート５３が遊離形態であれば、図７の如く、補修材５への合成樹脂液の含浸注入作業が容易であると共に、補修材５の取付管Ｐ１内周面への当接順応性、及び布材先端５１Ｅの鍔Ｒ形態での管口ＰＥへの当接性も良くなり、しかも、硬化処理後の内周面のシート５２（外側シートが反転したもの）の引き剥がしも容易である。
【００２０】
布材５１としては、合成樹脂を含浸保持し易い厚みを備え、且つ変形自在なもの、即ち、径及び長さ変化（縦、横変化）の容易な横メリヤスパイル布が好ましく、また、内外層のシート５３としては、施工過程で合成樹脂液を保持する機能を奏すれば良いが、反転作用で取付管Ｐ１内周面に当接する内側シート５３は補修後も取付管Ｐ１内周面と補修布材５１間に残存するため、取付管Ｐ１からの漏水を閉止する機能を発揮する耐水性フィルムが好ましく、ゴムシートを適用すれば、小地震等による補修更生管層５１への小振動応力も好適に吸収して補修取付管Ｐ１を保護する機能が期待出来るので好ましい。
また、外側シート５２は、反転により補修布材５１の内側となるため、補修施行後の反転ゴム４の引抜きと共に剥離破断出来るものが良い。
典型的には、外側シートも内側シートも、薄くて水不透過の合成樹脂フィルムが施工面、及び入手面から好適である。
【００２１】
また、補修材５の外側シート５２が先端に延出部５２Ｔを備え、布材５１が内側シート先端５３Ｔから補修材先端５１Ｅを突出しているのが好ましい。
この場合、外側シートの延出部５２Ｔのみを接続紐１２に止着して補修材先端５Ｔを反転ゴム先端４Ｔと接続出来、補修材５の硬化後の反転ゴム４の引抜き作用により、硬化補修材５の内面に存在する外側シート５２を小さな引張り力で補修布材５１からきれいに剥離除去出来、従って、延出部５２Ｔの存在により、補修材５の反転ゴム４との仮固定及び切離しが容易となる。
そして、延出部５２Ｔは、外側シート５２のみであって、反転ゴム４の反転作用によって布材５１の内側となるため、反転ゴム４の膨出バルーン４Ｂ形成時には、反転ゴム４の拡開作用によって破れるが、反転ゴム引抜き時には接続紐１２によって支障なく剥離脱去出来る。
【００２２】
また、外側シート５２の延出部５２Ｔには、図６（Ｄ）の如く、長手方向の裂け目Ｃ５２を形成しておくのが好ましい。
この場合、補修材５及び反転ゴム４の反転作用終了後の反転ゴム先端による膨出バルーン４Ｂ形成作業時に、反転ゴム４による外側シート５２の裂開が所定位置から縦方向にスムーズに遂行出来、膨出バルーン４Ｂで破られた外側シート５２が接続紐１２と連なった形態となるため、鍔Ｒの硬化処理後の反転ゴム４の引抜きに伴う接続紐１２による外側シート５２の剥離脱去が、スムーズに実施出来る。
【００２３】
また、反転ゴム基端４Ｅ及び補修材基端５Ｅを共に反転ガイド２に対して空密的に保持し、補修材５の反転中の先導部５Ｌに高圧流体ａの圧力を付与した状態で補修材５を反転ゴム４で反転挿入するのが好ましい。
補修材５を、先端５Ｔの垂れた状態で反転ゴム４によって反転挿入する場合は、取付管内面の直角屈曲角や小さな摩擦突起等により補修材５に皺を生ずる危険があるが、図１６に示す如く、補修材５の反転先導部５Ｌに高圧流体ａの圧力を作用させながら反転ゴム４に先導的に反転挿入するので、補修材５自体も反転ゴム同様に、取付管Ｐ１内の角や小突起に関係なく、膨張形態で平滑に順次反転挿入出来、従って、補修材５は皺を発生することなく取付管Ｐ１内に反転挿入出来て、補修布材先端５１Ｅも設計どおりに本管Ｐ０内に突出出来、結局、取付管Ｐ１内周面の形態に関係なく内面の平滑な取付管補修、及び取付管口ＰＥの均斉な鍔Ｒ被覆補修が可能となる。
【００２４】
また、反転ゴム４に反転機１からの高圧流体Ａを供給する反転ガイド２の流路に流路遮断用のバルブＶを配置し、反転ゴム４が補修材５全長を反転挿入して取付管Ｐ１内周面に圧接加圧すると共に、先端の膨出バルーン４Ｂで補修布材先端５１Ｅを管口ＰＥに鍔Ｒ形態で圧接した段階でバルブＶが反転ガイド２の流路を遮断し、反転ゴム４の高圧膨張状態を維持して補修材５を硬化するのが好ましい。
【００２５】
この場合、反転機１は、バルブＶの流路遮断作用中は圧力付与のための稼動の必要は無く、従って、比較的長時間を要する補修材５の硬化作業（自然硬化：８５〜１１５分）中は、反転機１は休止することが出来、バルブ作用によって反転機の稼動エネルギーが節約出来るのは勿論、反転機に次の作業の準備をすることも、或いは硬化作業中の反転ガイド２から反転機を切離して次の現場へ移動して稼動することも可能となるため、設備費のかかる反転機の稼動率向上が達成出来、排水取付管Ｐ１補修作業の経済的、合理的施工が可能となる。
【００２６】
また、バルブＶが反転ガイド２の流路に設けたゴム筒２５と、該ゴム筒２５の圧接手段３３，３４，３５とを含み、ゴム筒２５の圧接手段の下流には調整バルブＶ０を介した高圧流体調整用のチューブｔ１を付設するのが好ましい。
この場合は、ゴム筒２５を両側から圧接するだけでバルブＶの閉止が可能となるため、例えば、図９（Ｂ）に示す如き、進退用スクリューロッド３４の先端に圧接板３５を取付けた単純なバルブ開閉手段で容易に実施出来る。
しかも、消耗品としてのゴム筒２５の空密的取付けも、両端をバルブ装着用に切離した両側の反転ガイド端にバンドで空密的に締着するだけで可能であり、ゴム筒２５の取換えが容易となる。
【００２７】
そして、バルブＶには圧力計Ｍ及び調整バルブＶ０を設けてバルブＶの下流側（加圧力維持側）の圧力を検知し、圧力減が生じた際には、調整バルブＶ０から圧力流体を補充する慣用の圧力機器からチューブｔ１を介して圧力流体Ａ１を付加することにより、膨出バルーン４Ｂの高圧状態が維持出来、少々の圧力漏れの生ずる若干ラフなバルブＶの採用も可能となり、バルブの製作面からも、作業実施面からも有利となる。
【００２８】
また、本願補修方法の発明の実施に用いるための支持台車ＳＶは、図１０に示す如く、車輪９１を備え、ロープ９２ａによって前後移動可能な車台９０の前部と後部に一対の角度調整枠９３を配置し、下面にステ−９５を備えた支持プレート９４を前後の角度調整枠９３間に張設し、支持プレート９４の加圧降下によってステ−９５が着地し、車台９０の移動を阻止する構造である。
【００２９】
尚、角度調整枠９３は、支持プレート９４が反転ゴム４先端の膨出バルーン４Ｂを適切に支持出来るように、排水取付管Ｐ１の管口ＰＥの本管Ｐ０に対する接続角度に応じて車台９０に対して、即ち水平面に対して、支持プレート９４を傾斜調整付設可能とするものであるので、支持プレート９４を角度調整可能に取付けられれば良く、支持プレート９４を角度０°（水平）から左右４５°位まで調整傾斜可能であれば通常の排水取付管Ｐ１の補修が可能である。
また、ステ−９５は、支持プレート９４の自由状態、即ち、無負荷状態では、下端９５Ｅが車台９０の下面から若干下方に突出した形態に構成すれば良く、支持プレート９４の降下寸法との関係でステ−下端９５Ｅの突出寸法を決定すれば良い。
また、支持プレート９４は、前後両端をゴム板、スプリング等のバネ弾性を備えた形態で角度調整枠９３に取付ければ良い。
【００３０】
本発明の支持台車ＳＶは、支持プレート９４が排水取付管Ｐ１の管口ＰＥの取付角度に対応して角度調整の下に取付けるため、補修対象取付管Ｐ１に応じて支持プレート９４を管口ＰＥ面に平行に配置出来、反転ゴム４の頭部に形成する膨出バルーン４Ｂを、合理的に、且つ、補修布材先端５１Ｅが均斉な鍔Ｒを管口ＰＥの周囲に形成出来るように、支持プレート９４を配置出来る。
【００３１】
また、膨出バルーン４Ｂが支持プレート９４を押圧すれば、支持プレート９４の降下によってステ−下端９５Ｅが着地して支持台車ＳＶの移動を阻止するため、膨出バルーン４Ｂによる補修布材先端５１Ｅの鍔Ｒ形態での硬化処理中の長時間の押圧状態を適切に維持出来、鍔Ｒの硬化処理が高品質に実施出来る。
しかも、ステ−９５は、支持プレート９４の自由状態では、下端９５Ｅが地面から浮上った状態であるため、支持台車ＳＶの本管Ｐ０内での移動は、ステ−下端９５Ｅが本管Ｐ０底部の土石に妨害されずに、車輪のみで平滑に実施出来る。
【００３２】
また、本発明の支持台車ＳＶにあっては、前後の角度調整枠９３間に弾性変位可能にゴム板９６を張設し、支持プレート９４とステ−９５とをゴム板９６に挟着固定するのが好ましい。
この場合は、ゴム板９６の前端及び後端を角度調整枠９３に取付け、前後の角度調整枠９３と支持プレート９４の前後端の間にゴム板のみの弾性変位域９６Ｆを形成するだけで、支持プレート９４及びステ−９５に所望機能が付与出来、図１２の如く、ゴム板９６を、弾性変形域９６Ｆを残して上面の支持プレート９４と下面のステ−９５とで締着ボルト等で挟着固定すれば良いので、支持台車ＳＶの製作が簡単、且つ容易となる。
【００３３】
また、前後一対の角度調整枠９３が左右両側に調整孔Ａｈを備え、ゴム板９６の前後端部９６Ｅの左右側端を調整孔Ａｈへ選択固定して、ゴム板９６を車台９０に対して角度調整自在とするのが好ましい。
この場合、ゴム板９６の前後端の各左右側端と角度調整枠９３の調整孔Ａｈとを慣用の締着ボルト、係止ピン等で固定すれば良く、ゴム板側にネジボルトや係止ピンを付設して置けば良いが、図１２（Ｂ）の如く、ボルト孔９８ｈを備えた挟着板（取付プレート）９７Ｂを固定し、ゴム板の左右側端に亘って１本の調整ボルト（ネジボルト）９８を挿通するのが好ましい。
従って、ゴム板９６の前後端部９６Ｅを角度調整枠９３に選択固定するだけで、支持プレート９４は取付管口ＰＥの傾斜に対応した傾斜角に設定出来、ゴム板９６の着脱が容易であるため、各作業場所での支持プレート９４の傾斜調整が容易であると共に、消耗品であるゴム板の取換えも容易である。
【００３４】
また、本発明の支持台車ＳＶにあっては、図１１に示す如く、角度調整枠９３が環状板Ｃ９３であり、左右両側の略１／４周長に、スリットＳと切込み溝ｇ群から成る調整孔Ａｈを備え、ゴム板端９６Ｅに貫入した調整ボルト９８を調整孔Ａｈに係止するのが好ましい。
角度調整枠９３は、力学的強度付与に有利な環状板体であるため、比較的薄い鋼板での製作が可能となり、支持プレート９４の角度調整も、左右対称円弧の調整孔Ａｈ上での位置変更であるため、傾斜角調整も容易となり、支持プレート９４のゴム板９６やスプリング等の取付弾性部材の引張りによって調整ボルト９８をスリットＳ内で摺動させ、所定の切込溝ｇ内に再嵌合させることにより、支持プレート９４の角度調整も簡便に実施出来る。

また、本発明の支持台車にあっては、車台９０が、前部及び後部に広幅の取付部９０ａと、両取付部９０ａ間に細幅の連結部９０ｂとを備え、ステ−９５が連結部９０ｂを広く跨いでいるのが好ましい。
この場合、連結部９０ｂとその前後に連なる取付部９０ａとを、図１１に示す如き、上向き円弧凹面板とすれば、環状板Ｃ９３の固定が容易であると共に、比較的薄い鋼板でも十分な力学的強度が得られて有利である。
従って、ステ−９５が、連結部９０ｂを広く跨いでいるため、支持プレート９４の角度調整によるステー９５の必要傾斜回動も、車台の連結部９０ｂと干渉無しに実施出来る。
【００３６】
【発明の実施の形態】
本発明を宅内汚水桝から下水道本管に埋設連結した下水道取付管に実施する場合について詳述する。
本願発明の補修方法で下水道取付管Ｐ１の補修更生を実施する場合は、まず、事前調査工としての施工箇所の確認、障害物の確認をＴＶカメラで行い、次いで、事前処理工としての障害物等の除去を了えた後、図２に略示する如く、反転機１と、該反転機１に接続する反転ガイド２と、反転機１により巻取り巻戻しする反転ロープ１１によって反転ガイド２から出没させる反転ゴム４とを含む補修装置と、反転機１に高圧流体Ａを供給するための慣用のコンプレッサーとを用い、事前調査に基づいて選定準備した補修材５を該装置の反転ガイド２に装着し、反転ゴム４によって補修対象取付管Ｐ１内へ補修材５を反転挿入する。
【００３７】
次いで、補修布材先端５１Ｅが本管Ｐ０内に突出した状態で、本管Ｐ０内に対応配置した支持プレート９４に反転ゴム先端を当接加圧して膨出バルーン４Ｂを形成し、該バルーン４Ｂによって補修布材先端５１Ｅを鍔Ｒ形態に変形して取付管口ＰＥに圧接し、反転ゴム４による補修材５の取付管Ｐ１内周面、及び管口ＰＥへの加圧硬化を達成し、反転ゴム４を取付管Ｐ１内から抜取り、硬化した補修材の入口端部を処理して補修施工を終了する。
【００３８】
〔反転機（図８）〕
反転機１は、特願２０００−３０９１５８号の発明の実施に採用したものであって、本体が耐圧空密構造のドラム形態であり、図８に示す如く、車輪ＷとステイＹを備えた機台１４に支持脚１５及び調節脚１６で支持し、上部には作業用の開閉ハッチ１７、及びコンプレッサー（図示せず）と接続するための供給口金１８を設け、前方には反転ガイド２に接続するための接続口１９を備え、本体内部には外側のハンドル（図示せず）により回動させる巻芯１３を備えており、調節脚１６の調節孔ｈ群による本体前部の選択支持により接続口１９が上下に位置調節出来る構造である。尚、接続口１９先端にはカプラーＣ０を螺合し、反転ガイド２の基端との着脱を容易にしている。
また、機台１４が車輪ＷとステイＹとを備えているため、移動時は前方のステイＹを持ち上げて車輪Ｗによる移動を行い、現場に設置すればステイＹが反転機の移動を阻止するものである。
【００３９】
〔反転ガイド〕
反転ガイドも、特願２０００−３０９１５８号の発明の実施に採用したものであって、反転ガイド２全体構造は、反転機１側より、反転機１の接続口１９と接続するための第１ガイド片２１、第２ガイド片２２、弯曲した第３ガイド片２３、可撓ガイド片２０、及び弯曲した先端ガイド片２４相互を着脱自在に連結したものであり、第１ガイド片２１、第２ガイド片２２、第３ガイド片２３及び先端ガイド片２４は等径（１４０mm径）の軽量金属パイプであり、可撓ガイド片２０はサニーパイプ（商品名）である。
【００４０】
そして、図８に示す如く、第１ガイド片基端２１Ｅは、反転機１の接続口１９上のカプラー手段Ｃ０と螺合着脱出来る構造であり、第２ガイド片２２と第３ガイド片２３との間にはバルブＶを介装して着脱する構造（図９）であり、図２に示す如く、第３ガイド片２３下端にはクランプ手段Ｃ１を介して中空の第１接続管７を連結し、第１接続管７外周に可撓ガイド片２０上端をバンドＢ２により締着し、図３に示す如く、可撓ガイド片２０の下端は、中空の第２接続管８上端にバンドＢ３により締着し、図２に示す如く、第２接続管８の下端を先端ガイド片２４上端とクランプ手段Ｃ２で連結する構造である。
【００４１】
クランプ手段Ｃ１は、図４に示すとおり、第３ガイド片２３下端には係合環７１をネジＳ１，Ｓ２で螺合連結し、第１接続管７の上端の嵌入部７４を係合環７１内に嵌入してパッキン７１´に当接し、係合環上の係止片７２の回動により突起７２´を第１接続管７の嵌入部７４上の凹部７４´に嵌入止着する構造である。
また、クランプ手段Ｃ２は、図５に示す如く、先端ガイド片２４の上端に係合環８１をネジＳ３，Ｓ４で螺合連結し、第２接続管８下端の嵌合部８４内に係合環８１を嵌入してその上端を嵌合部８４のパッキン８４´に当接し、嵌合部８４上の係止片８２の回動により突起８２´を係止環８１上の凹部８１´に嵌入止着する構造である。即ち、クランプ手段Ｃ１とクランプ手段Ｃ２とは、共に係止片７２（８２）の手動起伏操作により、ワンタッチ着脱可能とする。
【００４２】
また、先端ガイド片２４は、中間部には口金ｔ０を配置し、加圧流体供給機（図示せず）からのチューブｔを口金ｔ０に接続して先端ガイド片２４の内周面に高圧流体ａ（図１６）の供給を可能とし、ガイド片２４先端外周には補修材５の基端５Ｅの空密締着を容易とするための締着溝Ｍを配置する。
また、第１接続管７には、図２に示す如く、ゴム製の弾性パイプ９を取付け、可撓ガイド片２０内を垂下させてその先端に反転ゴム基端４Ｅ装着用の取付部材１０を締着可能とする。
尚、先端ガイド片２４は、種々の取付管Ｐ１内径に対応した種々の径の補修材５が装着出来るように、先端２４Ｔの径のみの異なるもの（例えば、取付管径１００用の７５，１５０用の１３０，２００用の１７０）を用意しておく。
【００４３】
〔バルブＶ（図９）〕
バルブＶは、図９に示す如く、鉄板で溶接形成した方形筒のカバー３１を、取付片３２によって、第２ガイド片２２端から第３ガイド片２３端にかかり、ゴム筒２５を覆う形態に取付ける。カバー３１の中間部には補強板３１´で補強し、両側の補強板３１´にはガイドナットＮを固定し、各ネジロッド３４を各ガイドナットＮに螺合嵌入し、各ネジロッド３４の先端には厚さ３cm、幅２．５cmで長さがカバー３１の内面縦寸法に略等しいゴム製の角棒状の圧接板３５をネジロッド３４の回転が伝達されないように慣用の手段で取付け、ネジロッド３４の外側基端にはハンドル３３´を備えたプーリー３３を固定する。
【００４４】
そして、カバー３１の内面四隅には圧接板３５を両側から挟持する形態にガイド板Ｇを固定する。即ち、ハンドル３３´を回転すればネジロッド３４がガイドナットＮに案内されて出没し、各圧接板３５がカバー３１内で上下左右のガイド板Ｇに案内されながら前進又は後退出来る構造であり、両側の圧接板３５の内方進出作用によってゴム筒２５の中央部分を両側面から圧接出来る構造である。
尚、上下左右計８板の四隅のガイド板Ｇに換えて、カバー３１の内面にガイド溝を形成して圧接板３５の両端がガイド溝内を摺動するようにしても良い。
【００４５】
また、ゴム筒２５の内部と圧力計Ｍ及び調整バルブＶ０とは連通形態であり、ゴム筒２５内部の圧力低下を圧力計Ｍが検出すれば調整バルブＶ０を開いて高圧源（図示せず）から高圧流体（空気）を付加してゴム筒２５内部の圧力を所望の値に回復出来、高圧源と切離して調整バルブＶ０を開けばゴム筒２５内の高圧流体（空気）を放出出来る構造である。
【００４６】
〔反転ゴム４の装着（図２、図３、図６）〕
反転ゴム４は、反転ガイド２の内径より小径のゴム管であり、基端４Ｅを可撓ガイド片２０内に延出した取付部材に装着し、先端４Ｔを反転ロープ１１に係止する。
即ち、図２及び図３に示す如く、クランプ手段Ｃ１で第３ガイド片２３下端に着脱自在で第３ガイド片２３と略同径の金属製筒部材から成る第１接続管７の先端外周に、反転ゴム４より伸縮性が小で厚手のゴム管から成る弾性パイプ９の基端９Ｅを嵌めてスクリューバンドＢ５で空密的に締着し（図３）、弾性パイプ９の先端をプラスチック成形体の中空取付部材１０の基端１０Ｅ上に空密的にスクリューバンドＢ６で締着する。
【００４７】
そして、反転ガイド２内に挿通した反転ゴム４の基端４Ｅを取付部材先端１０Ｔ（図３）から外側へ折り曲げて取付部材１０の先端外周面にスクリューバンドＢ４で空密的に締着し、反転ゴム先端４Ｔは、図６に示す如く、中心にネジ孔Ｈ０を備えた閉止形態の５０mm径の面板部４１を有する円筒状の先端金具４０の外周に固定バンドで空密的に締着し、面板部４１の周縁部に突設した止め環４２に反転ロープ１１の先端を結び付け、反転ロープ１１の基端は反転機内の巻芯１３に係止巻回する。
【００４８】
〔補修材の準備（図７）〕
補修材５は、図７に示す如く、取付管Ｐ１と略同径で、ガラス繊維又は合繊のマルチフィラメントの太い無撚糸の横メリヤスパイル組織筒編物を布材５１として採用し、布材５１を被覆するシートとしてプラスチックフィルムを採用し、外側フィルム５２及び内側フィルム５３を重ねた各層間がルーズな３層構造筒状体であって、補修布材５１の長さは、補修対象取付管Ｐ１より１００mm前後長い物を用意する。
【００４９】
そして、図７（Ｃ）に示す如き、前後二対の絞りローラ５６を備えたテーブル５５を用いて布材５１と内側フィルム５３との層間に注入パイプ５７を挿入し、所定時間（２時間〜２時間３０分）で硬化するように設定したビニールエステル樹脂（又はポリエステル樹脂）を矢印Ｆ０の如く注入パイプ５７より注入し、絞りローラ５６で合成樹脂液を均質浸澗させながら絞って矢印Ｆ５の如く補修材５を取出す。
尚、補修材５の先端５Ｔ側では、図６（Ｃ）の如く、外側フィルム５２を布材５１端より更に外方に延びた延出部５２Ｔとし、内側フィルムの端部５３Ｔから布材先端５１Ｅを１５０mm突出させ、内側フィルム５３は取付管Ｐ１の先端から５０mm手前まで延出する形態とする。
【００５０】
〔補修材５の反転ガイド２への装着（図２、図６）〕
図６（Ｃ）に示す如く、補修材５の外側フィルム延出部５２Ｔを紐又は粘着テープ等で接続紐１２基端のループＬに固定すると共に、図６（Ｄ）に示す如く、延出部５２Ｔには、外側フィルム５２をスムーズに破裂させるために、縦方向に２０mm前後の裂け目Ｃ５２を形成し、紐１２を引張って補修材５の先端５Ｔが反転ゴム先端４Ｔ近くに到るまで反転ゴム４内に挿入し、図６（Ａ），（Ｂ）に示す如く、紐１２の先端を予め中空ボルト４３及び閉止ボルト４４を外した先端金具４０のネジ孔Ｈ０に挿通して、補修材先端５Ｔが反転ゴム先端４Ｔから適宜長さを保った状態で紐１２の先端部を中空ナット４３の中心小径孔Ｏ１を貫通した状態で中空ナット４３をネジ孔Ｈ０に螺着すると共に、紐１２の端部に結び目を形成して結び目を大径孔Ｏ２の底部に着座し、閉止ボルト４４の中空ボルト４３への螺着により紐１２の先端を先端金具４０に止着する。
【００５１】
また、補修材５の基端５Ｅは、図２に示す如く、先端ガイド片２４の端部２Ｔから外方に折曲げて先端ガイド片２４の溝Ｍ（図５）上にバンドＢ７，Ｂ８で締着する。
尚、補修材５の反転ガイド２内、及び反転ゴム４内への挿入時も、クランプ手段Ｃ１，Ｃ２を外して反転ガイド２を分割し、反転ゴム４を反転ロープ１１の巻戻しにより後方へ出した状態で作業すれば、補修材先端５Ｔの装着固定も、補修材５の反転ガイド２、及び反転ゴム４内への挿入も容易に実施出来る。
【００５２】
〔支持台車ＳＶ（図１０、図１１、図１２）〕
支持台車ＳＶは、図１０に示す如く、車輪９１を備えた車台９０と、車台９０の前後に取付けた角度調整枠９３と、角度調整枠９３間に張設したゴム板９６と、ゴム板９６の前後にゴム板露見部９６Ｆを残して、ゴム板９６の上面には支持プレート９４を、下面にはステ−９５を取付けたものであり、ステ−９５の下端９５Ｅが地面から浮上っており、角度調整枠９３には、調整孔Ａｈを形成し、車台９０の前後にはロープ固定環９２があり、ロープ固定環９２に牽引ロープ９２ａを取付け、マンホール（図示せず）から本管Ｐ０内に入れて本管Ｐ０内を移動させて取付管Ｐ１の補修施工に用い、施工作業終了後はマンホールから地上に回収するものである。
【００５３】
内径２５０mmの本管Ｐ０に好適に適用出来る支持台車ＳＶは、図１１に示す如く、車台は全長Ｌ９０が５５０mm、取付部９０ａの幅Ｗａが８０mm、連結部幅Ｗｂが３０mm、連結部長Ｌｂが３００mmであって、鋼板を円弧凹面に成形したものであり、前後取付部９０ａの下面の円弧凸面には、図１１（Ｃ）の如く、左右一対の車輪９１を円弧面から放射状に有し、中央の前後端部にはロープ固定環９２を備えている。
また、角度調整枠９３は、幅Ｗ９３が５０mm、径Ｄ９３が１８０mmの金属製環状板体であって、車台９０の取付部９０ａの凹曲面に固定したものであり、左右両側の各１／４周長に亘って、幅Ｗｓが１０mmのスリットＳと、スリットＳから切り込んだ幅Ｗｇが１０mmの溝ｇ群を備えた長尺の調整孔Ａｈを備えたものである。
【００５４】
また、図１２に示す如く、ゴム板９６は、幅Ｗ９６が１７０mm、長さＬ９６が５２０mmで、厚さｔ９６が５mmであり、ゴム板９６の両端には、幅Ｗ９７が６０mmの鋼製の上側取付プレート９７Ａと中央にボルト孔９８ｈを備えた下側取付プレート９７Ｂとを挟着してボルト９９で固定し、ゴム板９６の中央部には、幅Ｗ９４が２００mm、長さＬ９４が３００mmで１０mm厚の木製の支持プレート９４を上部に配し、下面には、支持プレート９４の前部及び後部にステ−９５を配し、支持プレート９４とステ−９５とでゴム板９６をボルト９９で挟着固定する。
【００５５】
また、ステ−９５は、図１２（Ｃ）に示す如く、車台９０を広く跨ぐように、ステ−下端９５Ｅ間を広くした２脚タイプとし、支持台車ＳＶの移動時には、本管Ｐ０内の土石と干渉しないように、図１０の如く、ステ−下端９５Ｅが地面より浮上った形態に配置する。
そして、ゴム板９６の角度調整枠９３への取付けは、ネジボルト９８を前後の下側取付プレート９７Ｂのボルト孔９８ｈ、及び角度調整枠９３の調整孔Ａｈの溝ｇに挿通し、蝶ネジ９８ｓで両端を固定する。
【００５６】
従って、本実施例の支持台車ＳＶは、本管Ｐ０内の移動は、ステ−９５が浮上ってステ−下端９５Ｅが土石に干渉しないで平滑移動出来、支持プレート９４に反転ゴムの膨出バルーン４Ｂの圧力が加われば、ステ−９５の着地によって膨出バルーン４Ｂを定位置で支持出来、また、支持プレート９４の角度変更は、両頭ネジボルト９８の調整孔Ａｈの所望溝ｇへの変更取付けにより可能であり、本管Ｐ０の径寸法に応じて、支持プレート９４の上下配置変更も、角度調整枠９３の上部又は下部にネジボルト９８の差渡し位置を変更することにより可能である。
【００５７】
〔取付管Ｐ１の補修工程〕
補修施工は下記の１）から１４）までの工程で実施する。尚、所要時間は、宅内汚水桝から本管への下水道取付管Ｐ１での所要時間である。
１） まず、補修の必要な取付管Ｐ１の内周面を高圧洗浄により洗浄する（所要時間約５分）。
２） 次いで、洗浄済取付管内部の状況を調査する（所要時間約５分）。
３） 次いで、反転機１を現場に設置し、反転ガイド２、反転ゴム４及び反転ロープ１１を準備し（所要時間約１０分）、同時並行作業で補修材５に樹脂を含浸する（所要時間約２０分）。
【００５８】
４） 次いで、合成樹脂を含浸させた補修材５を反転ゴム４内に引込み反転ガイド２に装着し、同時並行作業で支持台車ＳＶを調整して本管Ｐ０内に入れる（所要時間約２０分）。
５） 次いで、先端ガイド片２４の先端２Ｔを位置決め設置する（所要時間約５分）。
６） 次いで、用意した慣用のエアーコンプレッサー（図示せず）からチューブｔを介して先端ガイド片２４と補修材５との間に高圧空気ａを供給し、反転機１の本体ドラム内にも高圧空気Ａを供給し、図１６に示す如く、圧力計Ｍを見ながら反転ロープ１１を徐々に巻戻し（矢印Ｒ１）、チューブｔから供給した高圧空気ａで膨張した補修材先導部５Ｌで自力先行する補修材５と、高圧空気Ａで加圧膨張した後方の反転ゴム４とを取付管Ｐ１内へ反転進出させて、補修材５の全長が取付管Ｐ１内に挿入され、外側フィルム５２及び補修布材先端５１Ｅが本管Ｐ０内へ突出した状態を本管Ｐ０内のテレビカメラが検出した状態で反転作用を一時停止する（反転の所要時間約１０分）。
尚、補修材先導部５Ｌ内への高圧空気ａの供給は、反転ゴム４が反転開始して補修材５の内面に当接すれば供給不能となるが、その後、先導部５Ｌは高圧空気ａの封入された状態を維持して補修材５を先導し、補修材先端５Ｔが挟圧中の反転ゴム４から突出した状態（図１３）となれば、高圧空気ａは外側フィルム５２の裂け目Ｃ５２から放出する。
【００５９】
７） 次いで、図１３の如く、予め取付管Ｐ１の傾斜角に調整した支持台車ＳＶを、テレビカメラで目視しながら牽引ロープ９２ａによって補修管口ＰＥに位置合せする（所要時間約５分）。
８） 次いで、再び反転ロープ１１を徐々に緩め、反転ゴム４及び外側フィルム５２を本管Ｐ０内に出して、図１４の如く、支持台車ＳＶ上の支持プレート９４上に当接した段階で反転ロープ１１を固定保持する（所要時間約５分）。
９） 次いで、反転ゴム４内の圧力を最大圧０．８kg／cm２まで徐々に上昇させ、図１に示す如く、反転ゴム先端を外側フィルム５２の裂け目Ｃ５２から外側フィルム５２を破って突出させ、反転ゴム先端には支持プレート９４で支承された偏平形態の膨出バルーン４Ｂを形成して、管口ＰＥから１００mm突出した布材先端５１Ｅを管口ＰＥ周囲へ鍔Ｒ状に押圧する（所要時間約５分）。
【００６０】
１０） 膨出バルーン４Ｂの形成と同時にバルブＶを操作し、両側のゴム製の圧接板３５によってゴム筒２５を圧接して空密的に遮断した後、反転機１側の高圧空気を抜き、反転機１を開けて反転ロープ１１を巻芯から外すと共に、カプラーＣ０によって反転機１を第１ガイド片２１から切離して反転機を撤去する（所要時間約１０分）。
尚、切離した反転機１は次の現場へ移動し、前述の３）から９）までの工程遂行に使用する。
１１） 補修材の硬化（所要時間約８５分〜１１５分）
前述１０）の工程で反転機１を切離し撤去した後も、反転ガイド２は、補修材５の合成樹脂が硬化するまでは反転作業時の状態を維持し続け、圧力計Ｍによって硬化処理中の反転ゴム４の内圧（補修材５への圧接力）を維持管理し、内圧降下に対しては調整バルブＶ０からの高圧空気供給調整で対処する。
【００６１】
補修材５が硬化すれば、１２）管口切断（所要時間約１０分）、→１３）反転ガイド２の分解撤去及び管口仕上（所要時間２０分）、→１４）取付管内の補修状態調査確認（所要時間約１０分）する。
１本の取付管Ｐ１の標準的な補修施工は、以上の１）乃至１４）の工程で終了し、所要時間は約３時間である。
しかし、反転機１は、工程３）から工程１０）まででのみ使用するだけであるので、１台の反転機１を複数個所へ移動使用出来、反転機の稼動率が従来の工法での使用に比して３倍以上に高まる。
【００６２】
しかも、補修布材５１が横メリヤス筒編物であるため、布材先端５１Ｅが好適に拡開して鍔Ｒを形成し、管口ＰＥのクラックＫ１や隙間Ｋ２を完全に被覆し、内側フィルム５３を短くして取付管Ｐ１の管口ＰＥから管口ＰＥ周囲に亘る範囲を布材先端５１Ｅのみで接着硬化したため、従来の別途施工で補修する管口ＰＥの仕上げと同等、又はそれ以上の高品質の管口ＰＥの更生補修となる。
そして、取付管Ｐ１の本体部と本管Ｐ０内の管口ＰＥ部の補修施工が同時に実施出来るため、従来の本管Ｐ０内側からの排水取付管口ＰＥへの別途の施工が不要となる。
上述の施工順に従って略真直ぐな形態の取付管Ｐ１から略直角状屈曲部形態の取付管Ｐ１までの種々の形態の下水道取付管に就いて試験施工を実施したところ、満足な結果が得られた。
【００６３】
本実施例の施工にあっては、支持台車ＳＶは、車輪９１が車台９０の円弧下面から放射状に配置されているため、車輪９１が本管Ｐ０の底面の土石を避け、且つ、本管Ｐ０の円弧内面に略垂直に着地してスムーズに転がると共に、ステ−下端９５Ｅも浮上って土石と干渉しないため、牽引ロープ９２ａを引張るだけで本管Ｐ０内を水平姿勢でスムーズに移動し、所定位置で水平状態を維持する。
【００６４】
また、補修材先端の外側フィルム延出部５２Ｔには裂け目Ｃ５２が存在するが、反転作用の初期は、補修材５の大部分は反転ゴム４で挟圧されて送り出されるため、チューブｔから供給する高圧空気ａによって補修材５の膨出先導部５Ｌが形成出来、外側フィルム延出部５２Ｔの裂け目Ｃ５２が反転ゴム４の挟圧から開放されるまで、即ち、補修材５の布材５１の反転挿入終了の直前まで、先導部５Ｌ（図１６）が補修材５の反転をスムーズに遂行する。
そして、裂け目Ｃ５２が反転ゴム４から突出した段階（図１３）で高圧空気ａが裂け目Ｃ５２から出るが、以後の反転末期段階は、高圧空気Ａによって取付管Ｐ１周面に圧接して進行する反転ゴム４の作用により、補修材５は、布材先端５１Ｅが本管Ｐ０内に突出するまで取付管Ｐ１内周に圧接引伸ばし作用を受け、補修材５の反転挿入が出来る。
【００６５】
そして、図１４に示す段階では、即ち、補修材先端５Ｔ及び反転ゴム４の先端が支持台車ＳＶ上の支持プレート９４に当接して反転ロープ１１を固定した段階では、もはや外側フィルム５２内には高圧空気ａが存在せず、外側フィルム５２は、反転ゴム４への高圧空気Ａの加圧供給によって裂け目Ｃ５２からきれいに破れ、反転ゴム４は、外側フィルム５２から外側へ出てスムーズに膨出バルーン４Ｂを形成する。
従って、布材５１の硬化処理完了後の、反転ゴム４の引抜き時に、外側フィルム５２は、反転ロープ１１と連なる接続紐１２の引抜きによって硬化布材５１からきれいに剥離出来る。
【００６６】
また、反転ゴム４の先端の膨出バルーン４Ｂは、高圧の下での長時間（合成樹脂の硬化時間）維持となり、反転ゴム４の劣下を生じるが、支持プレート９４を管口ＰＥに略平行に保持して膨出バルーン４Ｂを均斉に偏平変形するため、比較的小径の膨出バルーン４Ｂでも布材先端５１Ｅの管口ＰＥへの鍔Ｒ形態での押圧が可能となり、消耗品である反転ゴム４の耐久性が向上し、管口ＰＥを被覆する鍔Ｒも均斉に仕上がる。
【００６７】
また、取付管口ＰＥが本管Ｐ０の曲面に開口しているため、鍔Ｒは、本管Ｐ０の長手方向に長く、円周方向に短い外周楕円形態となるが、布材先端５１Ｅを本管Ｐ０内に１００mm位突出させて補修すれば、図１６に示すクラックＫ１及び隙間Ｋ２の被覆は十分である。
しかも、補修材５の先端５Ｔ側では、内側フィルム５３が布材５１より１５０mm短く、取付管口ＰＥの５０mm手前までであるため、布材先端５１Ｅは、取付管口ＰＥから本管Ｐ０内面に亘るコーナーを屈曲して鍔Ｒを形成するため、鍔Ｒは、管口ＰＥに対する接着硬化となり、強固なる補修鍔Ｒを形成する。
【００６８】
〔変形例〕
補修材５は、実施例では、ゴム編みの横メリヤスパイル組織筒状布の布材先端５１Ｅを内側フィルム５３より突出させたが、補修材５の先端で布材５１と内側フィルム５３とを同長とし、補修布材先端５１Ｅと管口ＰＥとの間に内側フィルム５３が存在しても、布材５１は鍔Ｒ形態で硬化するため、更生補修管口ＰＥとしては、クラックＫ１や隙間Ｋ２を内側フィルム５３を介して閉止出来、実用上は支障を生じない。
また、布材先端５１Ｅは鍔Ｒ形態に拡開出来れば良く、従来のＬＩＰ工法等の補修布材の複数板重層タイプとし、先端５１Ｅに拡開用の縦方向切れ目を散在させ、各切れ目が重ならないようにしても、本発明の実施が可能である。
また、実施例では、外側フィルム５２の延出部５２Ｔに縦方向の裂け目Ｃ５２を設けたが、裂け目Ｃ５２は反転ゴム４が膨出バルーン４Ｂ形成時に外側フィルム５２を容易に破裂するためであるので、ミシン目又はピンホール等を設けても外側フィルム５２の破裂は容易となり、外側フィルム５２の材料を適切に選択すれば、裂け目Ｃ５２等の破断部を設けなくとも本発明は実施可能である。
【００６９】
また、実施例では、角度調整枠９３は環状板体としたが、車台９０の取付部９０ａの左側と右側に、一対の板状又はバー状片を平行立設して１つの角度調整枠とし、支持プレート９４及びステ−９５を備えたゴム板９６を一対の立設枠間に慣用の係止スプリングで調整自在に張設しても良い。
この場合は、傾斜角変更による立設枠間の寸法変化にも係止スプリングの伸縮で対応出来、同時に、適用本管の内径変化に応じた支持プレート９４の上下保持位置変化にも自在に対応出来る。
また、ステ−９５を、例えば、望遠鏡式等、長さ変更可能に形成しておけば、本管Ｐ０の径変化に対応した支持プレート９４の高さ位置調整が容易となり、ゴム板９６の降下によるステ−９５の着地保持作用が合理化出来る。
【００７０】
また、支持プレート９４及びステ−９５は、実施例ではゴム板９６に挟着固定したが、支持プレート９４の下面に長短調整可能のステー９５を固定し、支持プレート９４の前部及び後部の左右両側端縁からフックを備えた引張スプリングを延出し、引張スプリングのフックを角度調整枠９３の調整用孔Ａｈに調整自在に係止しても、所期の目的は達成出来、この場合は、支持プレート９４の傾斜角調整、及び支持プレート９４の本管Ｐ０の内径の変化に対応するステ−９５の作用位置調整（長さ調整）も容易である。
【００７１】
【発明の効果】
補修布材５１を含む補修材５は、高圧流体の作用で反転進出する反転ゴム４と共に反転ガイド２から取付管Ｐ１内へ連係して一緒に反転進出するため、補修更生対象の取付管Ｐ１が弯曲、或いは屈曲していても、反転ゴム４の反転挿入可能な取付管内へは機械的に挿通可能であり、しかも、反転ゴム４が寸法安定性に乏しい補修材５の挿入部分を順次拡開して取付管内周へ加圧して行くため、硬化補修材５は内周面が反転ゴム４の外周面によって平滑に仕上げられ、挿入部に補修材５内面に例え皺が発生していても、流水障害を生じない滑らかな状態に硬化処理出来る。
【００７２】
また、補修材５も反転ゴム４と共に反転ガイド２に装着した状態で取付管Ｐ１を更生補修施工するため、補修施工の準備作業の全てが、補修対象取付管Ｐ１から離れた地上での作業となり、作業性及び施工性が向上する。
また、施工時には、反転ゴム４及び補修材５を装着した反転ガイド２の先端２Ｔを補修対象の取付管Ｐ１入口部に近接配置出来るため、補修材５の必要材料長も補修対象取付管Ｐ１の必要補修長（取付管Ｐ１長＋鍔Ｒ長）と略同一と出来、従来の反転硬化法（ＬＩＰ工法）の如き補修材の先端部と基部での長寸の切断廃棄部分が生じなく、補修材５及び使用硬化剤（含浸合成樹脂）の使用量が最少限に節約、合理化出来る。
【００７３】
しかも、補修布材先端５１Ｅを本管Ｐ０内に突出した段階で、反転ゴム４の先端を支持プレート９４に当接した状態で反転ゴム４の反転作用を停止し、反転ゴム４内の高圧流体Ａの圧力のみを増加して、反転ゴム４の先端で膨出バルーン４Ｂを形成させるため、膨出バルーン４Ｂは、比較的小径のバルーンを横方向拡開偏平形態とすることにより、補修布材先端５１Ｅを管口ＰＥに鍔Ｒ形態で当接出来、鍔Ｒの形成が、反転ゴム４の膨出負荷を抑制して合理的に実施出来る。
そして、鍔Ｒは取付管Ｐ１の管口ＰＥを被覆当接して硬化するため、取付管Ｐ１から本管Ｐ０内へと連なるクラックＫ１も、取付管Ｐ１と本管Ｐ０との取付部の隙間Ｋ２を閉止補修出来る。
【００７４】
従って、本願補修方法の発明は、排水取付管Ｐ１の全長に亘る内周面と、取付管Ｐ１の本管Ｐ０への取付部の取付管口ＰＥとが同時に１本の補修布材５１によって更生補修出来、従来の取付管の補修施工と、取付管補修施工後に別途実施する取付管Ｐ１と本管Ｐ０との取付部の補修施工とが１本の補修材での１回の施工によって同時に実施出来、しかも、連続補修布材５１による高品質な更生補修管が得られるものであり、排水取付管の画期的な補修手段の提供を可能とするものである。
【００７５】
また、本願方法発明の実施に用いる支持台車ＳＶは、支持プレート９４を前後の角度調整枠９３間に張設するため、各補修対象取付管Ｐ１毎の本管Ｐ０への取付角度の相違に対しても、支持プレート９４が、補修対象取付管Ｐ１の取付角度に略平行形態に配置出来、支持プレート９４によって支承される反転ゴム４の膨出バルーン４Ｂを均斉な偏平変形バルーン４Ｂと出来、最少限に抑制された膨出バルーン４Ｂによる補修布材先端５１Ｅの均質確実な鍔Ｒの形成を可能とし、膨出バルーン４Ｂを高圧力で形成し、長時間維持する反転ゴムの劣下を最少限に抑制出来る。
【００７６】
また、支持プレート９４は下面にステ−９５を浮上り状態で保持しているため、支持台車ＳＶの本管Ｐ０内での移動時は、ステ−９５が本管Ｐ０底面の土石の干渉を受けないで平滑に移動出来、支持プレート９４が膨出バルーン４Ｂを支持する際は、ステ−９５が降下着地して支持台車ＳＶの移動変位を阻止し、膨出バルーン４Ｂの定位置での長時間支持が可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a method for repairing a drainage attachment pipe connected from a sewage basin or rainwater basin in a factory or home to the ground, and a repair device used in the method, and more specifically, installed in a factory or home. When an existing buried drainage pipe connected to a sewer main from a sewage basin or rainwater basin is cracked or damaged, a repair material layer is stretched on the inner surface of the mounting pipe without digging, and the mounting pipe It is related with the technology to rehabilitate.
[0002]
[Prior art]
[Patent Document 1] JP 2001-30357 A
In each household, there is a house slag, that is, a sewage slag, and the sewage sewage pipe from the sewage sewage main pipe is connected with a drainage sunk pipe buried in the ground. Due to aging, external loads, earthquakes, etc., breakage or seam breaks will occur, resulting in inflow of groundwater or earth and sand, or outflow of sewage into the ground. Become.
[0003]
The most common method for repairing and renovating the drainage pipe connected to the sewer main from the house pit is to dig out the buried pipe even if the pipe is simply cracked and leaking. In this method, the existing mounting pipe is removed and a new mounting pipe is installed and buried.
However, the excavation method in an urban area is not preferable from the viewpoint of the living environment such as adversely affecting traffic conditions and affecting neighboring residents because the road is dug up.
Therefore, in recent years, a non-cutting method instead of such a cutting method has been developed and put into practical use.
[0004]
Non-cutting methods include IPC (Inversion Chemical Pipe) breeze method and LIP (Lateral in Pipe) method reversal method. IPC breeze method reverses insertion of synthetic resin impregnated repair material from main pipe side to mounting pipe side. Compressed air is used to inject hot water into the repair material and harden the repair material. The LIP method attaches the end of the repair material on the sewage basin side of the house and repairs the existing installation pipe with compressed air. After the material is reversed and inserted and the repair material is cured, the portion protruding into the main pipe and the sewage basin is cut and removed.
[0005]
The present inventor has proposed an innovative new method for drainage pipe repair that is completely different from the IPC breeze method and the LIP method as Japanese Patent Application No. 2000-309158 (Japanese Patent Laid-Open No. 2001-30357).
That is, the proposed invention is shown in FIG. 16, and the repair material 5 impregnated with a curable synthetic resin is linked with the reversal rubber 4 and the connecting string 12 and mounted in the reversal guide 2 together. While supplying A, the reversing rubber 4 and the repair material 5 together with the reversing rope 11 are connected to the drainage mounting pipe P.116 and inserted into the mounting pipe P with the cloth material 51 of the repair material 5 as shown in FIG.1The covering material 51 of the repair material is cured in a state in which the inner surface of the drainage pipe is covered and pressure-welded, as shown in FIG.1The entire inner circumference is repaired and repaired with a hardened tube layer of the cloth material 51.
[0006]
[Problems to be solved by the invention]
In the revolutionary drainage pipe repair method of FIG. 16, the repair material is cured with the reversal rubber 4 pressed against the repair material 5. There will be no flaws that will cause trouble, and the surface will be smooth and the reversible rubber 4 will be able to be repaired on all mounting pipes that can be inserted in reverse. From the work surface, the quality of the repair and rehabilitation pipe Therefore, it is extremely excellent.
[0007]
However, as shown in FIGS. 16B and 16C, the mounting pipe P1Since the new renovated pipe layer is formed by the cloth material 51 on the inner peripheral surface of the drainage pipe P1At the pipe port PE, the mounting pipe P1Main P from inside0Crack K leading to the inside1And mounting pipe P1And main P0Gap K of the connecting part with2Cannot be repaired.
And crack K1And gap K2The existence of the main pipe P such as rainwater, groundwater, earth and sand from the formation around the mounting pipe0If necessary, separate main pipe P0It is necessary to repair the area around the mounting pipe PE with another repair material from the inside.
The present invention is an epoch-making improvement in the repair method shown in FIG. 16, and is attached by a single repair cloth material 51 in the implementation of the invention of Japanese Patent Application No. 2000-309158 (Japanese Patent Laid-Open No. 2001-30357). At the same time as repairing the inner peripheral surface of the pipe, the periphery of the mounting pipe PE can be repaired.
[0008]
[Means for solving the problems and actions]
  The invention of the repair method of the present application is, for example, as shown in FIGS. 1 and 2, the repair material 5 including the cylindrical repair cloth material 51 impregnated with the synthetic resin and the cylindrical reversal rubber 4 are linked to each other and reversed. Mounted in the guide 2, the reverse rubber 4 and the repair material 5 are removed from the reverse guide 2 by the action of the high-pressure fluid A on the reverse rubber 4.1The repair material 5 is inverted and inserted so that the repair material 5 is outside the reversal rubber 4.E(Fig. 13)0Protruding inward, reverse rubber 4 is connected to main pipe P0Against the support plate 94The reversal action of the reversing rubber 4 is stopped in the contact state, and then only the pressure of the high-pressure fluid A in the reversing rubber 4 is increased, and the swelling deformed between the support plate 94 and the pipe port PE at the tip of the reversing rubber 4.The out balloon 4B is formed, and the repair material 5 is attached to the mounting pipe P.1While pressing against the inner peripheral surface, the repair cloth material tip 51EMounting pipe P1The impregnated synthetic resin is cured in a state in which it is expanded and pressed into the shape of the ridge R covering the pipe PE, and after the repair cloth material 51 is cured, the reversal rubber 4 is pulled out, and the reversal guide 2 is separated from the repair material 5.
[0009]
In addition, as a repair cloth material, the conventional repair material which deform | transforms freely in a length direction and radial direction can be applied, and the cloth material front-end | tip 51 is applicable.ECan be used as a knitted fabric structure that can be expanded and deformed into a ridge shape, or as a layered form of a cloth with cuts for expansion, but typically it is capable of retaining and impregnating synthetic resin. It is a cylindrical knitted fabric of a horizontal knitted spire structure provided with.
Further, the bulging balloon 4B has a repair cloth material tip 51 as shown in FIG.EMay be pressed to the outside of the pipe opening PE in the form of a ridge R, and the deformed form of the bulging balloon 4B by the support plate 94 is also the repair cloth material tip 51EWhat is necessary is just to determine according to the dimension.
In addition, the cylindrical repair material 5 is linked to the cylindrical reversal rubber 4 as long as the repair material 5 is reversely inserted when the reverse rubber 4 is reversely inserted.EIs held by the reversing guide, and the repair cloth tip 51EMay be drawn into the inside of the reversal rubber 4.
Further, the support plate 94 supports the bulging of the head of the reversal rubber 4 and the bulging balloon 4B is fixed to the repair cloth material tip 51.EThe bulging balloon 4B may be regulated so as to press the pipe port PE against the pipe port PE, and the main pipe P is manually operated.0Even plate material placed and fixed inside, or main pipe P0The board | plate material attached to the chassis which can move within may be used.
[0010]
In addition, here, "attachment pipe P1”On the surface of the earth, including mounting pipes connected to the main sewer pipe from the house basin, drainage pipes connected to the main sewer pipe from rainwater tanks in the home and factory, and drainage pipes from the wastewater treatment tanks in the factory. Drainage main pipe P underground from the installed water reservoir (桝)0This means the underground pipe that is connected to the (sewer main), and “inverted rubber” can be used to form the bulging balloon 4B, such as synthetic rubber, natural rubber, or other sheet material having rubber elasticity. The term “synthetic resin” broadly means a synthetic resin that is light-cured, heat-cured, or naturally cured (cured with time), and “fluid” refers to air, heated, or room temperature water. , Meaning gas and the like.
[0011]
Accordingly, the repair material 5 is attached to the attachment pipe P from the reversing guide 2 together with the reversing rubber 4 which receives the high-pressure fluid action.1Since the reverse rubber 4 is reversely inserted and linked together, all the places where the reverse rubber 4 can be reversely inserted can be reversely inserted into the repair material.1Even if is bent or bent, the repair pipe P1An insertion arrangement inside is possible.
Furthermore, since the repair material 5 having poor dimensional stability is reversed to the outside of the reversal rubber, the reversal insertion portion of the repair material is sequentially applied by the expansion pressure of the reversal rubber 4 and the attachment pipe P1Pressed by the inner peripheral surface, the mounting pipe P1Occurrence of wrinkles of the repair material at the bent portion of the repair material is minimized, and even if wrinkles that occur slightly, the inner peripheral surface of the repair material 5 that is in contact with the reversal rubber 4 by pressurization of the reversal rubber 4 has no problem as a flow path. The surface becomes smooth.
[0012]
Further, the reversal insertion work of the repair material 5 is performed by attaching the tip of the reversing guide 2 to the mounting pipe P.1The required length of the repair material 5 is the installation pipe P to be repaired.1It can be set according to the length of the material, and there is no long cutting waste part at the tip and base of the repair material like the conventional reverse hardening method (LIP method), and the use of materials such as repair material and synthetic resin is streamlined I can do it.
Furthermore, the preparatory work for the reverse insertion of the repair material 5 is the mounting pipe P to be repaired.1Because it can be carried out on the ground away from the site, construction preparation work can be streamlined.
[0013]
  In addition, the repair material tip 51EThe main P0Protruding inAnd antiThe tip of the roller 4 contacts the support plate 94AddedIn order to inflate, the bulging balloon 4B has a relatively small diameter balloon.ButLateral expansiondidFlat formNextRepair material tip 51ECan be brought into contact with the pipe port PE in the form of ridges R, and the formation of the ridges R can be carried out rationally while minimizing the load of the reversal rubber.
  And 鍔 R is the mounting pipe P1In order to abut and harden the pipe port PE, the mounting pipe P as shown in FIG.1From main P0Crack K1And mounting pipe P1And main P0Gap K of the mounting part with2Can be repaired, the repair of the present invention isBy the reversing action of the reversing rubber 4,In addition to repairing and repairing the inner peripheral surface of the mounting pipe, it is possible to repair the mounting pipe port PE, which was previously only possible with separate construction.
  Therefore, according to the present invention, the mounting pipe P1The entire inner circumference of the pipe and the mounting pipe P1Main P0At the same time, the pipe PE of the attachment part can be rehabilitated and repaired by the repair cloth 51, and it is possible to provide an epoch-making repair means for the drainage attachment pipe.
[0014]
  Further, in the invention of the repair method of the present application, the reversing action of the reversing rubber 4 is stopped while the reversing rubber 4 is in contact with the support plate 94, and then only the pressure of the high-pressure fluid A in the reversing rubber 4 is increased. The tip of the reversal rubber 4 is a bulging balloon 4B that is flatly deformed between the support plate 94 and the pipe port PE.The
  As shown in FIG.0Can be moved withinYesRepair material tip 51EIs the main P0Reverse work when exposed insideTo stopSupport plate 94ofMounting pipe port PEEasy to place.
  And since the reverse rubber 4 fixes the protrusion length of a front-end | tip by contact | abutting to the support plate 94, the swelling load of the reverse rubber 4 can be suppressed to the extent required for formation of the collar R.
[0015]
  Therefore,According to the present invention,Since the reversing action of the reversing rubber is stopped while the reversing rubber 4 is in contact with the support plate 94, the amount of protrusion of the tip of the reversing rubber 4 can be minimized, and the bulging balloon 4B restricted by the support plate 94 can be prevented. Due to the flat shape deformation, the repair material tip 51EThe bulging balloon 4B having a relatively small flat shape in which the bulging load of the reversing rubber 4 is regulated can be rationally pressed against the bulging rubber 4 and the tip 51 of the repair cloth material.EIt is possible to form the ridges R necessary for covering the pipe port PE.
[0016]
In the invention of the repair method of the present application, the support plate 94 is attached to the mounting pipe P.1It is preferable to arrange substantially parallel to the pipe opening PE.
The meaning of “substantially parallel to the pipe opening PE” means that the virtual plane of the pipe opening PE and the support plate 94 are substantially parallel, and the main pipe P0This means that the support plate 94 is also inclined.
Therefore, since the support plate 94 is arranged substantially parallel to the pipe opening PE, the flattening deformation of the bulging balloon 4B at the tip of the reversal rubber 4 by the support plate 94 is uniform with respect to the pipe opening PE, and a relatively small bulging balloon. Even if it is 4B, the cloth material tip 51EThe uniform soot R can be formed reasonably by the above, and the durability of the reversal rubber 4 which is easily deteriorated and easily damaged is improved.
[0017]
In addition, the base end 5 of the repair material 5EThe tip 2 of the reversing guide 2TFastened to the outer periphery of the repair material tip 5TIs pulled into the reverse rubber 4, and the reverse rubber tip 4 is connected to the connection string 12.TAnd the reversing rubber tip 4 on the reversing rope 11 rewound from the core 13 of the reversing machine 1TDrainage attachment pipe P from reversing guide 2 of reversing rubber 41It is preferable to reversely extend the repair material 5 to the outside of the reverse rubber 4 by reversely extending inward.
In this case, the connecting string 12 and the repair material tip 5TCan be connected by temporary fixing that is weak enough to be released by the pulling action of the reverse rubber 4.
[0018]
Therefore, repair material base 5EIs the tip 2 of the reversing guide 2TThe tip of the reversing guide 2 of the repair material 5TThe reversing action from is smooth and the reversing guide tip 2TMounting pipe P1By constructing in the vicinity of the mouth portion, the disposal length of the repair material 5 after repair can be saved to a minimum, and the use material can be rationalized.
Furthermore, repair material tip 5TAnd reverse rubber tip 4TSince the connection string 12 exists between them, the work of inserting the repair material 5 into the reversal rubber 4 is facilitated by pulling the connection string 12, and the repair material 5 and the reversal rubber 4 are attached to the reversal guide 2. Work becomes easy. The reversing rubber 4 has the entire length of the repair material 5 attached to the mounting pipe P.1Repair material tip 5 even after reverse insertionTThe bulging balloon 4B at the tip of the reversing rubber can be selectively formed, and by applying pressure over the entire length of the repairing material 5 including the heel R portion, the attachment pipe P of the repairing material 5 is applied.1It is possible to carry out the press hardening of the inner peripheral surface over the entire length of the inner peripheral surface and the flange R of the mounting pipe PE uniformly.
[0019]
Moreover, it is preferable that the repair material 5 includes at least three layers in the form of a free multilayer of a cloth material 51 impregnated with a synthetic resin, an outer sheet 52, and an inner sheet 53.
If the cloth material 51, the outer sheet 52, and the inner sheet 53 are free, the impregnation / injection work of the synthetic resin liquid into the repair material 5 is easy as shown in FIG.1Adaptability to contact with inner peripheral surface and cloth material tip 51EIn addition, the contact property to the pipe opening PE in the shape of the heel R is improved, and the sheet 52 on the inner peripheral surface after the curing process (in which the outer sheet is inverted) can be easily peeled off.
[0020]
The cloth material 51 is preferably a horizontal knitted fabric having a thickness that can easily be impregnated and held with a synthetic resin and is easily deformable, that is, a diameter knitted fabric that can easily change in length and length (vertical and horizontal changes). As the sheet 53, it is only necessary to have a function of holding the synthetic resin liquid during the construction process, but the mounting pipe P can be reversed.1The inner sheet 53 in contact with the inner peripheral surface is attached to the mounting pipe P even after repair.1Since it remains between the inner peripheral surface and the repair cloth 51, the mounting pipe P1A water-resistant film that exhibits the function of closing water leakage from the water is preferable. If a rubber sheet is applied, the small vibration stress applied to the repair and rehabilitation pipe layer 51 due to a small earthquake or the like is suitably absorbed and the repair mounting pipe P1Since the function which protects can be anticipated, it is preferable.
Moreover, since the outer side sheet | seat 52 becomes inside the repair cloth material 51 by inversion, what can peel and fracture | rupture with drawing | extracting of the inversion rubber 4 after repair execution is good.
Typically, for both the outer sheet and the inner sheet, a thin and water-impermeable synthetic resin film is preferable from the viewpoint of construction and availability.
[0021]
Also, the outer sheet 52 of the repair material 5 extends to the tip 52.TThe cloth material 51 has an inner sheet front end 53.TFrom repair material tip 51EIt is preferable to protrude.
In this case, the extended portion 52 of the outer sheetTOnly fix the connection string 12 to the repair material tip 5TReverse rubber tip 4TThe outer sheet 52 existing on the inner surface of the cured repair material 5 can be peeled off and removed from the repair fabric material 51 with a small tensile force by the pulling-out action of the reversal rubber 4 after the repair material 5 is cured. Part 52TDue to the presence of, temporary fixing and separation of the repair material 5 from the reversal rubber 4 are facilitated.
And the extension part 52TIs only the outer sheet 52 and becomes the inner side of the cloth material 51 by the reversal action of the reversal rubber 4. Therefore, when the bulging balloon 4B of the reversal rubber 4 is formed, it is broken by the reversal action of the reversal rubber 4. When pulling out, the connecting string 12 can be removed and removed without any trouble.
[0022]
Further, the extending portion 52 of the outer sheet 52TIn this case, it is preferable to form a slit C52 in the longitudinal direction as shown in FIG.
In this case, the tearing of the outer sheet 52 by the reversal rubber 4 can be smoothly performed in the vertical direction from the predetermined position at the time of forming the bulging balloon 4B by the reversal rubber tip after the reversal action of the repair material 5 and the reversal rubber 4 is completed. Since the outer sheet 52 torn by the bulging balloon 4B is connected to the connection string 12, the outer sheet 52 is peeled and removed by the connection string 12 with the withdrawal of the reverse rubber 4 after the heel R is cured. Can be implemented smoothly.
[0023]
Inverted rubber base 4EAnd repair material base 5EAre both kept airtight with respect to the reversing guide 2, and the leading portion 5 during the reversal of the repair material 5.LIt is preferable to reversely insert the repair material 5 with the reverse rubber 4 in a state where the pressure of the high-pressure fluid a is applied thereto.
Repair material 5 with tip 5TIn the case of reversing and inserting with the reversing rubber 4 in the state where it hangs down, there is a risk that wrinkles may occur in the repairing material 5 due to a right angle bending angle or a small friction projection on the inner surface of the mounting tube, but as shown in FIG. Inversion lead 5LSince the pressure of the high-pressure fluid a is applied to the reversal rubber 4, the repair material 5 itself is attached to the mounting pipe P in the same manner as the reversal rubber.1Regardless of the corners and small protrusions inside, it can be smoothly inserted in reverse in an expanded form, so the repair material 5 can be attached to the mounting pipe P without generating wrinkles.1It can be inverted and inserted into the repair cloth material tip 51.EIs the main P as designed0Can project inward, and eventually, the mounting pipe P1Irrespective of the form of the inner peripheral surface, it is possible to repair the mounting pipe with a smooth inner surface and to repair the uniform 鍔 R coating of the mounting pipe port PE.
[0024]
Further, a valve V for blocking the flow path is arranged in the flow path of the reversing guide 2 for supplying the high pressure fluid A from the reversing machine 1 to the reversing rubber 4, and the reversing rubber 4 reversely inserts the entire length of the repairing material 5 into the mounting pipe. P1While pressure-contacting and pressurizing the inner peripheral surface, the repair cloth material tip 51 is formed by the bulging balloon 4B at the tip.EIt is preferable that the valve V blocks the flow path of the reversing guide 2 at the stage where it is pressed against the pipe port PE in the form of a ridge R, and the repair material 5 is cured while maintaining the high-pressure expansion state of the reversing rubber 4.
[0025]
In this case, the reversing machine 1 does not need to be operated for applying pressure during the flow blocking action of the valve V.

Open the reversing machine 1 and remove the reversing rope 11 from the winding core.0Thus, the reversing machine 1 is separated from the first guide piece 21 and the reversing machine is removed (required time is about 10 minutes).
Note that the separated reversing machine 1 moves to the next site and is used to perform the processes from 3) to 9) described above.
11) Curing of repair material (required time: about 85 to 115 minutes)
Even after the reversing machine 1 is separated and removed in the step 10), the reversing guide 2 keeps the state of the reversing operation until the synthetic resin of the repair material 5 is cured. Maintains and maintains the internal pressure of the reverse rubber 4 (pressure contact force to the repair material 5), and adjusts the valve V against the internal pressure drop.0This is dealt with by adjusting the high pressure air supply.
[0061]
If the repair material 5 is hardened, 12) cutting the pipe opening (required time is about 10 minutes), → 13) disassembling and removing the reversing guide 2 and finishing the pipe opening (required time 20 minutes), → 14) investigating the repair state in the mounting pipe Confirm (requires about 10 minutes).
One mounting pipe P1The standard repair work is completed in the above steps 1) to 14), and the required time is about 3 hours.
However, since the reversing machine 1 is only used in steps 3) to 10), one reversing machine 1 can be moved to multiple locations and the operating rate of the reversing machine can be used in the conventional method. It is three times higher than
[0062]
In addition, since the repair cloth material 51 is a horizontal knitted tubular knitted fabric, the cloth material tip 51ESuitably expands to form ridges R and cracks K in the pipe opening PE1And gap K2Is completely covered, the inner film 53 is shortened, and the mounting pipe P1The leading end 51 of the cloth material extends from the pipe opening PE to the periphery of the pipe opening PE.EAs a result of the adhesive hardening only, it is a rehabilitation repair of a high quality pipe opening PE equivalent to or higher than the finishing of the pipe opening PE repaired by conventional separate construction.
And the mounting pipe P1Main body and main P0Because it is possible to carry out repair work on the PE port in the pipe at the same time, the conventional main pipe P0There is no need for separate construction from the inside to the drainage attachment pipe port PE.
According to the above-mentioned construction order, the mounting pipe P has a substantially straight shape.1To mounting pipe P in the form of a substantially right-angled bend1When the test construction was carried out on various types of sewer installation pipes up to the present, satisfactory results were obtained.
[0063]
In the construction of the present embodiment, the support carriage SV has the wheels 91 arranged radially from the bottom surface of the arc of the chassis 90, so that the wheels 91 are connected to the main pipe P.0Avoid the stones on the bottom of the main and P0The lower end of the step 95EWill not interfere with the debris, so just pull the tow rope 92a and the main P0The inside moves smoothly in a horizontal posture and maintains a horizontal state at a predetermined position.
[0064]
Also, the outer film extension 52 at the tip of the repair materialTIn the initial stage of the reversal action, most of the repair material 5 is clamped by the reversal rubber 4 and sent out, so that the high pressure air a supplied from the tube t guides the bulge of the repair material 5. Part 5LCan be formed, the outer film extension 52TUntil the tear C52 is released from the clamping pressure of the reverse rubber 4, that is, until just before the reverse insertion of the cloth material 51 of the repair material 5 is completed.L(FIG. 16) performs the reversal of the repair material 5 smoothly.
Then, the high pressure air a exits from the tear C52 at the stage where the tear C52 protrudes from the reversal rubber 4 (FIG. 13).1Due to the action of the reversal rubber 4 that advances in pressure contact with the peripheral surface, the repair material 5 is made of the cloth material tip 51.EIs the main P0Mounting pipe P until it protrudes in1The repair material 5 can be reversely inserted by being subjected to a pressure-stretching action on the inner periphery.
[0065]
Then, at the stage shown in FIG.TAt the stage where the tip of the reverse rubber 4 abuts on the support plate 94 on the support carriage SV and the reverse rope 11 is fixed, the high pressure air a no longer exists in the outer film 52, and the outer film 52 4 is torn cleanly from the tear C52 by the pressurized supply of high-pressure air A to 4, and the reverse rubber 4 exits from the outer film 52 to form the bulging balloon 4B smoothly.
Therefore, when the reversal rubber 4 is pulled out after the curing process of the cloth material 51 is completed, the outer film 52 can be cleanly separated from the cured cloth material 51 by pulling out the connection string 12 connected to the reverse rope 11.
[0066]
Further, the bulging balloon 4B at the tip of the reverse rubber 4 is maintained for a long time under high pressure (curing time of the synthetic resin), resulting in inferiority of the reverse rubber 4, but the support plate 94 is substantially omitted from the pipe port PE. Since the bulging balloon 4B is uniformly flattened while being held in parallel, even the bulging balloon 4B having a relatively small diameter is used as the cloth material tip 51.EIt is possible to press the pipe port PE in the form of 鍔 R, the durability of the reversal rubber 4 which is a consumable is improved, and the heel R covering the pipe port PE is finished uniformly.
[0067]
The mounting pipe PE is the main pipe P0鍔 R is the main pipe P.0The outer peripheral ellipse shape is long in the longitudinal direction and short in the circumferential direction.EThe main P0If it is repaired by protruding about 100 mm inside, the crack K shown in FIG.1And gap K2The coating of is sufficient.
Moreover, the tip 5 of the repair material 5TOn the side, the inner film 53 is 150 mm shorter than the cloth material 51 and is up to 50 mm before the attachment pipe port PE.EThe main pipe P from the mounting pipe port PE0Since the corner extending over the inner surface is bent to form the ridge R, the ridge R is bonded and hardened to the pipe opening PE to form a strong repair ridge R.
[0068]
[Modification]
In the embodiment, the repair material 5 is a cloth material tip 51 of a rubber knitted horizontal knitted spill tissue tubular cloth.EIs projected from the inner film 53, but the cloth material 51 and the inner film 53 have the same length at the tip of the repair material 5, and the repair cloth material tip 51EEven if there is an inner film 53 between the pipe PE and the pipe PE, the fabric material 51 is cured in the form of ridges R.1And gap K2Can be closed via the inner film 53, and there is no practical problem.
Also, the cloth material tip 51EAs long as it can be expanded into a ridge R shape, it is a multi-layered type of repair cloth material such as the conventional LIP method, and the tip 51EIt is possible to implement the present invention even if the vertical cuts for spreading are scattered and the cuts do not overlap.
In the embodiment, the extending portion 52 of the outer film 52 is also shown.TAlthough the tear C52 is provided in the longitudinal direction, the tear C52 is for the reverse rubber 4 to easily rupture the outer film 52 when the bulging balloon 4B is formed. If the material of the outer film 52 is appropriately selected, the present invention can be implemented without providing a breakage portion such as a tear C52.
[0069]
In the embodiment, the angle adjustment frame 93 is an annular plate, but a pair of plate-shaped or bar-shaped pieces are provided in parallel on the left and right sides of the mounting portion 90a of the chassis 90 to form one angle adjustment frame. The rubber plate 96 provided with the support plate 94 and the stage 95 may be stretched between a pair of standing frames so as to be adjustable by a conventional locking spring.
In this case, it is possible to respond to changes in dimensions between the standing frames by changing the inclination angle by expanding and contracting the locking spring, and at the same time, it is also possible to freely change the vertical holding position of the support plate 94 according to changes in the inner diameter of the main pipe I can do it.
Further, if the stage 95 is formed so that the length can be changed, for example, a telescope type, the main pipe P0Accordingly, the height position of the support plate 94 can be easily adjusted in accordance with the diameter change, and the landing holding action of the stage 95 due to the lowering of the rubber plate 96 can be rationalized.
[0070]
Further, in the embodiment, the support plate 94 and the stage 95 are clamped and fixed to the rubber plate 96, but a stay 95 that can be adjusted in length is fixed to the lower surface of the support plate 94, and the left and right sides of the front and rear portions of the support plate 94 are fixed. Even if the tension springs with hooks are extended from both side edges and the hooks of the tension springs are adjusted and locked in the adjustment holes Ah of the angle adjustment frame 93, the intended purpose can be achieved. Adjustment of the tilt angle of the support plate 94 and the main pipe P of the support plate 940It is easy to adjust the operating position (length adjustment) of the stage 95 corresponding to the change in the inner diameter.
[0071]
【The invention's effect】
The repair material 5 including the repair cloth material 51 is attached to the attachment pipe P from the reversing guide 2 together with the reversing rubber 4 that reverses and advances by the action of the high-pressure fluid.1In order to work together and turn over together, mounting pipe P for repair and rehabilitation1Even if bent or bent, the reversing rubber 4 can be mechanically inserted into the reversible insertion fitting tube, and the reversing rubber 4 sequentially expands the insertion portion of the repair material 5 having poor dimensional stability. Since the cured repair material 5 is opened and pressurized toward the inner periphery of the mounting pipe, the inner peripheral surface of the cured repair material 5 is finished smoothly by the outer peripheral surface of the reversal rubber 4, and even if wrinkles are generated on the inner surface of the repair material 5 at the insertion portion. Curing treatment can be performed in a smooth state that does not cause running water damage.
[0072]
The repair material 5 is also attached to the reversing guide 2 together with the reversing rubber 4 in the mounting pipe P.1In order to carry out rehabilitation repair work, all the preparation work for repair work is the installation pipe P to be repaired.1Work on the ground away from the work is improved and workability and workability are improved.
Further, at the time of construction, the tip 2 of the reversing guide 2 with the reversing rubber 4 and the repair material 5 attached thereto.TRepair pipe P to be repaired1Since it can be placed close to the inlet, the required material length of the repair material 5 is also the repair target mounting pipe P1Required repair length (Mounting pipe P1The length of the repair material 5 and the used curing agent (LIP construction) can be made substantially the same as the conventional reversal hardening method (LIP method). The amount of impregnated synthetic resin) can be minimized and streamlined.
[0073]
  In addition, the repair material tip 51EThe main P0The tip of the reversing rubber 4 comes into contact with the support plate 94 when protruding inwardIn this state, the reversing action of the reversing rubber 4 is stopped, and only the pressure of the high-pressure fluid A in the reversing rubber 4 is increased to form the bulging balloon 4B at the tip of the reversing rubber 4.Therefore, the bulging balloon 4B has a relatively small-diameter balloon in a laterally expanded flat shape so that the front end 51 of the repair cloth material is obtained.ECan be brought into contact with the pipe opening PE in the form of ridges R, and the formation of the ridges R can be carried out rationally while suppressing the bulging load of the reverse rubber 4.
  And 鍔 R is the mounting pipe P1Since the pipe mouth PE is covered and cured,1From main P0Crack K leading to the inside1The mounting pipe P1And main P0Gap K of the mounting part with2Can be repaired.
[0074]
Therefore, the invention of the repair method of the present application is the drainage pipe P1The inner peripheral surface over the entire length of the mounting pipe P1Main P0The attachment pipe port PE of the attachment part can be repaired and repaired at the same time by one repair cloth 51, and the conventional installation pipe repair work and the installation pipe P to be performed separately after the installation pipe repair work1And main P0The repair work of the attachment part can be carried out simultaneously by one work with one repair material, and a high-quality rehabilitation repair pipe with the continuous repair cloth 51 can be obtained. It is possible to provide innovative repair means.
[0075]
Further, since the support carriage SV used for carrying out the method invention of the present application stretches the support plate 94 between the front and rear angle adjustment frames 93, each repair target mounting pipe P1Main P every0Even if the mounting angle is different, the support plate 94 is attached to the mounting pipe P to be repaired.1The bulging balloon 4B of the reversal rubber 4 supported by the support plate 94 can be made into a uniform flat deformation balloon 4B, and the repair cloth material by the bulging balloon 4B suppressed to the minimum. Tip 51EIt is possible to form a uniform and reliable ridge R, to form the bulging balloon 4B at a high pressure, and to minimize the deterioration of the reversal rubber that is maintained for a long time.
[0076]
Further, since the support plate 94 holds the stage 95 in a floating state on the lower surface, the main pipe P of the support cart SV.0When moving inside, the stage 95 is connected to the main P0When the support plate 94 supports the bulging balloon 4B, it can move smoothly without receiving interference from the bottom of the earth and stone, and the stage 95 descends to prevent the displacement of the support carriage SV, and the bulging balloon 4B. Long-term support at a fixed position is possible.
