Six advantages of slip form paver

① Good dynamic evenness: due to continuous long-distance paving, the dynamic evenness of slip form pavement is far more than that of concrete pavement constructed by manual small machines and tools. It is difficult for manual small machines and tools to achieve the evenness of cement concrete pavement of 3M, and the straightedge is less than 3mm. Sliding construction can completely achieve the evenness level of asphalt concrete, The smoothness of cement concrete pavement will be better and better.

② , high strength, high density: as the vibration of the Slipform Paver is high frequency vibration. The vibration frequency is as high as 12000 times / min, which is dozens of times of manual vibration. The vibrator of wittgens SP850 slipform machine in Germany is hydraulic type. Its advantage is that the vibration frequency can be adjusted according to the slump of concrete on site, so that the concrete can be vibrated. At the same time, the uniformity of the paver is good (there will be no leakage vibration and other phenomena). Secondly, the concrete panel of slipform construction is formed by self weight and high strength extrusion of paver, which greatly improves the compactness of concrete. High density will inevitably produce high strength. We have done comparative tests. With the same concrete mix proportion, the bending strength of slipform construction is about 15% higher than that of manual construction, and it is less affected by human factors, so the guarantee rate of construction quality is high.

③ Construction speed, high degree of automation: paver by hydraulic sensor system automatic control of concrete center line and elevation, construction cloth vibration, extrusion, forming, pull rod, do surface and other processes in one go, on the basis of concrete mixture supply can keep up, each working shift can complete 800-1000 meters of road.

④ Long service life, low maintenance cost and significant long-term benefits.

⑤ Remarkable economic benefits: with the progress of science and technology, cement concrete pavement is widely used in all levels of highways. The reason: one of the outstanding points of cement concrete is its remarkable economic benefits. At present, the asphalt used on high-grade highways in our country basically depends on imports, which has huge investment and is not conducive to stimulating the local economy. On the contrary, cement is one of the pillar industries in China. Large output, low price and construction of cement concrete pavement can give full play to the advantages of domestic cement, which not only reduces the project cost, but also drives the development of local economy.

⑥ Low carbon environmental protection, less pollution to the environment.
