在施工中采用了许多新材料和新工艺，主要有电气绝缘、轨道板的吊装与铺设、CA砂浆、轨道板的张拉等。应用了高度可调节的底座板模板，改进了轨道板粗铺定位方法，从而保证了施工精度要求；设置的临时端刺以及移动门式起重机配合吊车的轨道板吊装就位方法加快了施工进度。工程实践证明，该法精度高，施工工期短，经济效益明显。 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. |
