Description
本考案は、橋梁工学の分野、具体的に橋梁ケーブル保護用複合シースに関する。 The present invention relates to the field of bridge engineering, specifically, a composite sheath for protecting bridge cables.
橋梁ケーブルシステムは、吊橋、斜張橋、アーチ吊橋の主な耐荷重構造であるが、河川や湖にまたがる過酷な作業環境（潮汐腐食、風侵食、応力腐食など）にあるので、事故が発生すると、橋梁が発火しやすく、ケーブルが変形したり、橋本体も倒壊したりして、損傷が発生すると、非常に重大な安全事故や経済的損失を引き起こすことになる。したがって、橋梁構造物の安全を確保するためには、ケーブルを保護する必要がある。日本では、カルシウム鉛酸や高分子有機鉛などで構成された改良型パテ材（ＨＳ）を使用して、アクリル樹脂プライマー＋ＨＳパテワイヤーラップ＋塩素化ゴムトップコートの保護システムを形成している。中国の保護システムは、最初のアスファルトのコーティングの後、ガラス繊維布で包み、次にエポキシ樹脂でコーティングし、ガラス布を３層包むことから、現在の亜鉛メッキ鋼線の熱間押出した高密度ポリエチレン（ＰＥ）層保護システム、即ち高強度複合テープをワイヤーロープの外側に巻き付けた後、熱押し出したＰＥ層まで、長年にわたって開発されてきたが、輸送や施工などの過程で多少の欠陥があるため、ケーブルの寿命が短くなるなどの重大な問題につながる。 The bridge cable system is the main load-bearing structure of suspension bridges, cable-stayed bridges, and arch suspension bridges, but accidents occur due to the harsh working environment (tidal corrosion, wind erosion, stress corrosion, etc.) that straddles rivers and lakes. Then, the bridge is easily ignited, the cable is deformed, the bridge body is collapsed, and damage occurs, which causes a very serious safety accident and economic loss. Therefore, in order to ensure the safety of the bridge structure, it is necessary to protect the cable. In Japan, an improved putty material (HS) composed of calcium lead acid, high molecular weight organic lead, etc. is used to form a protection system of an acrylic resin primer + HS putty wire wrap + chlorinated rubber top coat. China's protection system first coats asphalt, then wraps it in fiberglass cloth, then coats it with epoxy resin, and wraps the glass cloth in three layers, thus hot-extruded high density of current zinc-plated steel wire. A polyethylene (PE) layer protection system, a high-strength composite tape wrapped around the outside of a wire rope and then heat-extruded, has been developed for many years, but has some defects in the process of transportation and construction. Therefore, it leads to serious problems such as shortening the life of the cable.
