The popularization and application of automatic control system of milling machine

Application of milling machine in pavement construction are more common on the application of milling machine in practical work, in this small series was summed up, and to share with you.

In the process of highway engineering construction, it is often necessary to transform or upgrade the old road surface. However, the old pavement pavement condition is poor, many places have emerged uneven situation, appear to hold the bag, rutting, pavement subsidence, milling large construction difficulty. So, if the milling on the pavement by milling method, it can only rely on the plate edge milling machine, is very limited for the existence of some of the original pavement flatness problem.

The application of automatic leveling system in milling machine can improve operation accuracy, decrease the cost, especially in the special sections of the renovation and rutting of pavement on the old road, has a good application effect. Below, we take the actual construction as an example, analysis of the specific application of milling machine automatic level control system in actual construction.

But because the edge plate milling machine is short, so it is only for copy milling is simple, can not change the shape of the original pavement. And the specific pavement leveling, but also with the paver automatic leveling system to complete.

But if the roughness of the original pavement is poor and the error has exceeded the design thickness, it will lead to too thin paving on the pavement, and even the mixture can not be paved. And the paver in the process of operation, general, paving to the high position of the road, will raise the screed.

Moreover, the uneven thickness of the paving also greatly causes the waste of the mixture, and can not get satisfactory results. In practical operation, in order to meet the requirements of the owner, often need to ensure the original design of slope pavement milling, but simply rely on the side plate of the milling machine for leveling, unable to meet the actual needs of the owners. Even make use of cross slope milling machine, must be in the side as a reference.

In the lower part of the road, the oil will be too thick, resulting in uneven paving degree. If the roller is used for rolling, the wave will appear and the roughness is poor.

But in the actual operation process, it is difficult to find a good linear and smooth edge, and even can not find it at all. So, we need to use the automatic leveling system to solve these problems.
