The construction steps of the synovial paver are briefly described 2, what are the construction methods of bored piles?
The slide type paver does not need a template, and the track paver needs a template
Slip form construction is a construction technology of cast-in-place concrete project. Compared with the conventional construction method, the construction process has fast speed, high degree of mechanization, can save formwork and scaffolding required quantity, can be more convenient and flexible assembly and break up the template can be used repeatedly. This method is often used in reinforced concrete chimneys and circular structures. The lifting power of slipform construction generally adopts hydraulic device, that is hydraulic jack. At present, many sliding mode projects adopt large tonnage hydraulic jacks.At present, there are two main ways, one way to light mechanical configuration, the main work done by machinery, auxiliary work done by hand and small machines, large concrete mixing paving site configuration of large Slipform Paver and supporting the social rented vehicle concrete by bulldozers or digging cloth, do not configure cloth machine and napping, life, health napping done by hand. Another heavy chain mechanical configuration in large synovial paver configuration before and after the spreader and galling life, and configuration of large frame type multi blade cutting machine, the background configuration of large concrete mixing building enough, while 8~24 m share 3 of the allocation of transport vehicles, to achieve full mechanization and rapid construction.Control of the key process is mainly: 1, paver speed should be controlled in 1m/s, not much material quickly, no material stop wait; 2, truck unloading meters height not more than 1.5 meters, with anti segregation of aggregates; 3, duringpacking shall not throw throw.
The slide type paver needs a template track paver and needs a template
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.
