1. The Double Pursuit of Efficiency and Precision in Modern Pavement Construction
Against the background of the continuous advancement of global infrastructure construction, high-quality asphalt pavement has become the core demand of road engineering. Whether it is the upgrading of urban trunk roads, or the expansion of highway network extension, the smoothness, durability and service life of the pavement construction has put forward stringent standards.
However, the traditional asphalt pavement construction, long-term faced with a number of pain points: asphalt sprinkling uneven pavement quality varies, material waste seriously increase construction costs, the discontinuity of the production chain is directly slowing down the progress of the project. In order to solve these industry problems, a fully automatic asphalt sprinkler equipped with advanced technology, with the appropriate continuous mixing equipment to stabilize the supply, for modern pavement construction to inject new vitality.
2. The core advantages of Full Automatic Asphalt Distributor
1) Intelligent control: Siemens PLC and colorful touch-screen operation
The sprinkler is equipped with Siemens PLC control system and TFT colorful touch-screen operation interface, which realizes one-button operation in the driver’s cab. The operator can complete the spraying volume setting directly in the cab, and the system can automatically match the speed of the vehicle and display the asphalt pump flow, asphalt temperature, liquid level and other key data in real time, so that there is no need to frequently go back and forth to different operation areas of the body, which greatly enhances the convenience and intelligence level of the construction, and allows one person to complete the whole operation process.
2) Extreme spraying precision: full-width coverage without dead angle
adopts folding rear spraying bar design, the maximum spraying width can reach 6 meters, which can be adapted to the construction needs of different widths of road surface. It is equipped with a maximum of 39 nozzles, and each nozzle is independently operated by a solenoid valve-controlled pneumatic cylinder, which can be adjusted in any combination according to the construction environment. Whether it is large area sprinkling of conventional road surface or precise operation of complex road sections such as curves and ramps, it can realize uniform coverage of the whole width without dead angle and ensure stable and reliable sprinkling quality.
3) Efficient Heating and Energy Saving: Independent Energy Management System
In terms of the heating system, the Italian RIELLO G20 burner is selected to be matched with a 5KW generator drive, which realizes the separate operation of the heating system and the truck engine. This design not only saves 70% of fuel consumption, but also avoids the extra loss caused by long time running of the engine.
At the same time, the equipment adopts U-shaped burner tube lined with thermal oil coils, the heat can be synchronously transferred to the asphalt tank, asphalt pumps and spraying rods, through the Siemens temperature control system to accurately regulate the temperature of the thermal oil, effectively preventing asphalt in the process of conveying and spraying due to the temperature is too low for the aging of the pipeline clogging and other problems, to protect the continuity of the construction.
4) Convenience of maintenance: double cleaning and self-priming function
In order to prolong the service life of the equipment, both sides of the asphalt tank are equipped with toolboxes, and both air cleaning system and diesel cleaning system are integrated. After the construction is completed, the pipeline and pump body can be fully cleaned through the double cleaning system to avoid residual asphalt curing affect the performance of the equipment. The new generation of products also added automatic self-priming function, further simplifying the operation and maintenance process of the equipment, reducing the cost of manual maintenance.
3. Application Scenario: Covering the whole life cycle of road
1) Pervious layer and adhesive layer construction in new construction
In the new construction of road, the construction quality of the pervious layer and adhesive layer directly affects the adhesion between the structural layers of the pavement. The spreader can accurately control the asphalt spreading rate between 0.25-3.0 L/m² to ensure that the asphalt uniformly penetrates into the grassroots or adheres to the surface layer, which effectively enhances the integrality of each structural layer of the pavement, improves the road’s load-bearing capacity and resistance to water damage, and lays a solid foundation for a high-quality pavement.
2) Preventive Maintenance: Chip Seal
Preventive maintenance is the key means to prolong the service life of a road that has been put into use. In the Chip Seal operation, the sprinkler can work together with the gravel spreading equipment, first evenly sprinkle a layer of asphalt binder, and then synchronously spread gravel to form a solid protective layer. This process can effectively repair minor cracks on the pavement, aging and other diseases, restore the anti-skid performance and waterproof performance of the pavement, compared with the traditional overhaul program, with low cost and short construction period of significant advantages.
3) Special terrain and large-scale road and bridge construction projects
In the construction of mountain roads, bridges and tunnels and other special terrain, the stability and adaptability of the equipment is crucial. Sprinkler trucks rely on sturdy chassis design (optional Dongfeng, Haworth and other well-known brands of chassis), can adapt to the transportation and operational needs of complex road conditions. Its accurate control of the sprinkler can meet the strict requirements of the road and bridge project on the amount of asphalt sprinkler, to ensure that the project successfully passed the quality acceptance.
4. The construction of the upstream quality assurance: Continuous Asphalt Mixing Plant
construction site of efficient sprinkling, inseparable from the back-end of the stable, high-quality asphalt mixture supply. Zoomline machinery Continuous Asphalt Mixing Plant can realize continuous production of 20-200t/h to meet the material demand of different scales of projects, and its modular design facilitates rapid transfer and installation, and the sprinkler trucks form an efficient construction connection to ensure the smooth advancement of the process.
5. Synergistic Application Value: Creating Efficient Construction Chain
1) Enhance the overall progress of the project
The uninterrupted production of the continuous mixing equipment can provide the construction site with a continuous and stable supply of mixed materials, avoiding the interruption of the material source that leads to the stagnation of the sprinkler operation. The efficient spraying ability of the sprinkler trucks can quickly apply the material to the road surface, which can reduce the waiting time of the process and significantly accelerate the construction progress.
2) Reducing overall operation and maintenance costs
The independent heating system of the spreader truck echoes the low-consumption design of the continuous mixing plant, which reduces fuel costs. At the same time, both types of equipment have convenient maintenance characteristics, which can reduce downtime and lower labor and spare parts operation and maintenance costs.
3)Digital Project Management
The PLC control system of the sprinkler truck can record the amount of sprinkles and vehicle speed during the construction process. If it is paired with the production data collection function of the mixing equipment, it can be used to realize the digital monitoring of the key aspects of the construction process through the simple data interoperability in the future, which can provide the basic support for the tracing of the project quality.
6. Choose reliable equipment, achievement of high-quality projects
This automatic asphalt sprinkler truck with 20 years of technical accumulation, the product footprint has been all over the world’s 65 countries and regions, in all kinds of road projects to show excellent performance and reliability.
With its core advantages of intelligence, high precision and energy saving, it has become the preferred equipment for modern pavement construction, and with the stable supply of continuous mixing equipment, it can provide a powerful assistance for the project to improve quality and efficiency. In the context of high-quality development of infrastructure construction, the selection of high-quality, automated construction equipment is not only the key to improve the quality and efficiency of the project, but also an important way to enhance the core competitiveness of enterprises.
