Combined with the basic plan of the asphalt mixing plant equipment, a series of survey preparation work should be done before the installation of the asphalt mixing plant equipment to ensure that the power lines, water supply pipelines, and oil supply pipelines are installed on site. Preliminary preparations: Before the installation of the asphalt mixing plant, preliminary observation of the terrain was made, a topographic plan was drawn, the elevation relative to the ground was determined, and the construction team was arranged to level the site. Then make a preliminary arrangement on the topographical plan according to the topographical plan and the basic plan of the asphalt mixing plant equipment. The stone storage, the location of the mechanical equipment, the transportation lane, the powder area, the operating room, the fuel supply area, the asphalt supply area, the pipeline, the power line, Control lines, living areas, etc. are arranged separately so that each area is relatively suitable, without interfering with each other, without affecting each other, compact installation, convenient operation and observation. Finally, draw a construction drawing and put the line on site for excavation construction.
Basic construction: During the installation of the asphalt mixing plant, the asphalt mixer building is higher than the ground and the column load is heavy, which is the focus of the entire asphalt mixing plant. Therefore, it is determined that the foundation plane of the four columns of the mixing building and the finished product silo column is a relative elevation of ±0.00. First excavate the foundation of the four columns of the mixing building and the finished silo column, the depth of which is not less than 1.5m, and the base surface pressure Foundation degree ≥25N/cm2 can be implemented. C1# concrete is placed under 1m away from elevation ± 0.00; reinforced mesh is placed above 1m, and embedded steel reinforcement is placed, and c25 cement concrete is placed to elevation. In order to ensure the overall strength of the foundation, the four columns are connected by ∮14 threaded steel mesh; in order to prevent the earthquake from causing the rack to fall over, the overall quality of the foundation is determined to be ≥ 2 times the quality of the mixer building. For the excavation and pouring of the foundation of other components, it is required that the bearing capacity of the foundation surface ≥15N/cm2 can be carried out according to the size and structural requirements of the drawing.Asphalt Mixing Plant
