What are the slip type paver and track paver?
Slide type paver does not need template, it uses its own protruding formwork for laying, construction speed, quality is goodRail type spreading machine, first laying the template, and then spreading, and now generally use the sliding model paver mainly.For the concrete pavement and severe heavy traffic levels, transverse expansion and contraction joints will be dowels, because the general case is not a contraction joint dowel bar basting.
Slipform paving technology began in mid 1960s 1963, the world's first paver manufacturer by Belgium's SGME-Moser manufacturing, imagine the Slipform Paver is mainly to solve the fixed template construction method is time-consuming, improve work efficiency. But there are many other defects, and the continuous research and improvement of Germany, America, Switzerland and other countries have been perfected and put into use constantly, thus opening up the era of large-scale use of Slipform Paver in the world. Now the world's manufacturers are mainly the United States CMI and COMACO company, Powercuber company, Germany's Wittgen company and so on, while Belgium's SGME-Moser company gradually decline, in 1970s bankruptcy.China's earliest introduction of Slipform Paver is introduced in 1986 by the American Powercuber company curb paver, type 2000 road in Heilongjiang province in 1989 from the American COMACO company with Slipform Paver, and Jiangxi in 1990, Hubei has introduced the United States, COMACO2000 and 2500, until 2000, the provinces of our country has a variety of slide spreading machine more than 30 Taiwan, the Slipform Paver process of high grade highway 2100 kilometers.The use of rail paver [1], found some correct use method, the paper introduced the factors effecting smoothness and pay attention to the problem, and the influence of cement concrete pavement quality of the stand itself, at the same time, some methods to improve the paving quality.
