跨座式单轨交通系统有三大关键技术:机车、道岔、PC梁。这种城市轨道交通,具有投资省、占地少、噪音低、客运能力大等优点。PC梁是一种预应力混凝土结构,梁体采用钢绞线、YM型锚具、钢筋骨架、一次性内模、C60混凝土浇注及后张法预应力施工工艺。中铁二十三局集团六公司(以下简称“六公司”)制造PC梁专用的高精度可调式模板、PC梁梁体和工法获得三项国家专利。重庆市轻轨交通在国内首开先河,轻轨PC梁是国内空
Hurdle monorail system has three key technologies: locomotive, turnout, PC beam. This kind of urban rail transit has the advantages of investment saving, small land occupation, low noise and large passenger capacity. PC beam is a kind of prestressed concrete structure. The beam body is made of steel strand, YM anchorage, steel skeleton, disposable internal mold, C60 concrete pouring and post-tensioned prestressed construction technology. China Railway 23th Bureau Group Six Company (hereinafter referred to as “six companies ”) to create PC-beam-specific high-precision adjustable template, PC beam body and method to obtain three national patents. Chongqing City, the first light rail traffic in China, light rail PC beam is empty
