In order to meet the needs of foreign projects, and considering the impact of transportation costs, management costs, equipment purchase costs and other factors, construction enterprises usually remove the existing asphalt mixing plant to the project site and set up a mobile asphalt mixing plant. Whether a mobile asphalt mixing plant can be set up quickly is an important factor to determine whether it can be put into operation early and ensure the project progress. Therefore, this paper analyzes the construction of mobile asphalt mixing plant.
You can access the official asphalt website of Lutong Asphalt Equipment Professional Manufacturer to learn more about the asphalt station.
The establishment of mobile asphalt hot mix plant (the web version detailed information is here) mainly includes site selection, planning and construction, demolition, commissioning and production of asphalt mixing plant.
1. Site selection of mobile asphalt mixing plant (the mobile asphalt batching plant is one type, seen here)
The site selection of the mixing plant shall not only consider the impact on the surrounding residents and environment, but also consider the economic rationality. Therefore, the following factors shall be taken into account in site selection:
(1) The distance between the location of the mixing station and the asphalt pavement paving construction site should be reasonable. It is better to build the mixing station near the midpoint of the construction bid section for transportation. The transportation channel is convenient, so as to save the transportation cost of finished materials and improve economic benefits. At the same time, consider whether the water and electricity sources are convenient.
(2) There should be a certain distance from residential areas and ecological crop areas to minimize the impact of noise, smoke and dust on the surrounding environment, avoid unnecessary environmental complaints, and establish a good construction image and corporate image.
(3) The site can provide sufficient space for placing, storing and running the mixing plant. The geological conditions are good, and the leveling and solidification costs of the site are the lowest.
2. Site planning and construction of mobile asphalt mixing plant
The site planning of asphalt mixing plant shall be scientific and reasonable to maximize the utilization and effectiveness of the site and meet the production demand as much as possible.
3. Demolition of asphalt mixing plant
Generally, in the process of building a mobile asphalt mixing plant, the demolition speed of the asphalt mixing plant is the key factor to determine the construction progress. In order to economically and quickly complete the demolition of the mixing plant, three aspects of work should be done well:
(1) According to the characteristics of the equipment, plan the disassembly sequence of the mixing plant.
(2) Select the appropriate disassembly team.
(3) Strengthen on-site regulation and reasonable division of labor.
(4) Do a good job of equipment transportation safety to ensure that the equipment is not damaged and the components are not missing.
4. Commissioning and production of asphalt mixing plant
After the installation of the asphalt mixing plant is completed, the commissioning can be carried out. First of all, pressure test shall be carried out on the pipeline to ensure that there is no leakage at all welds of the pipeline and between the heat transfer oil pipeline and the asphalt pipeline. If leakage is found, it shall be repaired in time and pressure test shall be carried out again until no leakage is found. Secondly, the mixing plant shall be fully maintained, and the power supply system and control system shall be subject to necessary reliability testing. Then, the mechanical parts shall be powered on and tested in the way of inching control to see whether the control effectiveness and the rotation direction of each motor are correct. After all inching controls are successful, the whole mixing plant shall be tested by automatic control. Then, the accuracy of the electronic measuring scale is verified and calibrated. Finally, the screening test and grading design of aggregate are carried out, and the trial production is carried out. The finished material can be put into production after passing the inspection.
