Problems solved by technology

[0002] Core wall roller compacted asphalt concrete paving machinery is the key machine for the construction of hydraulic earth-rock dam RCC anti-seepage core wall construction. The paving construction of domestic hydraulic earth-rock dam core wall RCC and transition materials relies on imports Equipment solution, only a few large foreign companies can manufacture hydraulic earth-rock dam anti-seepage core wall roller compacted asphalt concrete paver, its price and maintenance costs are high, which increases the project cost of the construction unit
Moreover, the maximum thickness of asphalt mixture paving of earth-rock dam anti-seepage core wall roller compacted asphalt concrete paver produced by foreign manufacturers is only 23cm, and it does not have temperature detection, electric control ignition, mixture insulation and heating power adjustment according to heating temperature, etc. At the same time, it is difficult to operate the transitional material paving width adjustment slide plate, and the transitional hopper car scraper does not have a visual control switch independent of the laser control system
