In highway construction, the construction effect of laser concrete leveling machine is the best. Bulldozers: cutting force is enough, but the width is not enough, the efficiency is low, it is not easy to automatically leveling, roughness is difficult to grasp, operation is complex, and the density uniformity of roadbed material is more difficult to grasp. Milling machine milling shaping effect is good, the effect is obvious, but the cost is high, single function, rectification, in the old road renovation in use.
The lime soil mixing method mostly adopts road mixing method. According to the requirement, we use manual grader to mix the ash manually, and the road mixer is mixed in many ways. When the width is bigger, it is scraped with a grader, and then compacted. When the grader is manually paved with ash, the thickness error is large, the process is many, the construction period is long, the road mixer is mixed many times, the grader scraps normally, the auxiliary operation machinery is many, the process is many, the allocation is complex.
Some laser concrete leveling machines in China have shallow mixing depth, which may lead to hidden danger of plain soil interlayer. Meanwhile, because of mechanical turbulence and unstable operation, the error of mixing roadbed height is large or uneven. In the mixing stage, some foreign road mixing machines can be used, such as the good quality of the mixing machine and good crushing performance.
The laser concrete leveling machine is one of the indispensable machinery in the construction, so it is necessary to stick to the principle of quality priority when selecting and buying machines.
