Asphalt mixing stations are constructed according to a certain process, which can not only ensure the construction quality, but also ensure that the asphalt mixing station is not damaged. Although construction details are critical, the key skills of asphalt mixing station construction must be mastered.
Before the construction of the asphalt mixing station, the top surface of the asphalt mixing station construction range should be removed, and the site elevation should be kept dry and flat to meet the design requirements. If the surface is too soft, the foundation should be reinforced to prevent the construction machinery from losing stability and ensure that the pile frame is vertical.
Then the on-site construction machinery should be inspected to ensure that the machinery is intact and assembled and tested under the premise of meeting the requirements. The verticality of the asphalt mixing station should be ensured, and the deviation of the gantry guide and the mixing shaft from the verticality of the ground should not exceed 1.0%.
Regarding the layout of the asphalt mixing station, it should be operated according to the pile position plan layout diagram, and the error should not exceed 2CM. The asphalt mixer is equipped with 110KVA construction electricity and Φ25mm water pipes to ensure that its power supply and various transportation management are normal and stable.
When the asphalt mixing station is positioned and ready, the mixer motor can be turned on, and the wet spraying method can be used to pre-mix the cut soil to make it sink; after the mixing shaft sinks to the designed depth, the drill can be lifted and sprayed at a speed of 0.45-0.8m/min.
