在施工中采用了許多新材料和新工藝,主要有電氣絕緣、軌道板的吊裝與鋪設(shè)、CA砂漿、軌道板的張拉等。應(yīng)用了高度可調(diào)節(jié)的底座板模板,改進了軌道板粗鋪定位方法,從而保證了施工精度要求;設(shè)置的臨時端刺以及移動門式起重機配合吊車的軌道板吊裝就位方法加快了施工進度。工程實踐證明,該法精度高,施工工期短,經(jīng)濟效益明顯。 many new materials and new technology were adopted in the construction, mainly including electrical insulation, the hoisting and laying of track plate, CA mortar, the tensioning of track plate and so on. The technology, which are application of height-adjustable base plate moulding board and improving the method of track plate rough pavement positioning, ensured the construction precision. The setting of temporary end thorn and mobile gantry crane with derrick truck for hoisting and laying of track plate sped up the construction progress. Engineering practice indicates that the improved technology has advantages of higher precision, shorter construction period, and obvious economy benefit. |
