Several Methods for Controlling Elevations of Runway Pavers

There are many methods for controlling the elevation of pavers, which can be roughly divided into the following methods. Let's take a look together:
Physical benchmark method. Control the height of the paving material by setting physical benchmarks next to the rubber paver. This method is easy to operate and cost-effective, but requires setting up benchmark locations on site and adhering to strict benchmark elevation requirements. The physical benchmark method may result in errors due to the displacement or damage of the benchmark.
Laser control method. During the construction process of the runway paver, laser electronic ranging instruments are used to measure the ground height and determine the elevation level. This method has high accuracy, fast control speed, and can be used for long-distance control, but requires on-site installation of paving equipment and distance measuring instruments for fine maintenance, which is costly and may be affected in adverse weather conditions.
GPS control method. Determine the position and height information of the rubber paver through precise satellite positioning. This method has high accuracy and can be controlled over a large range without the need for physical benchmarks. However, it requires certain operational skills and maintenance costs, and may result in errors in narrow construction environments.
Manual adjustment. Suitable for simple ground subgrade construction. The operation includes finding the height adjustment device of the runway paver, adjusting it to the design requirements, and maintaining consistent height during the construction process.
Automatic adjustment. Using laser or GPS devices with small errors to automatically adjust the height of the rubber paver, improving construction efficiency and accuracy. This is usually achieved by inputting elevation information into the paver through an onboard computer and setting the control height before construction.
Fixed reference method (suspension line method). Use fixed benchmarks, such as high-strength steel wires with a diameter of 2 millimeters, to accurately control the design elevation, pavement thickness, and smoothness. The operation includes setting the steel wire reference line, monitoring the elevation of the upright pole, and maintaining its stability during the construction process.
Contact span floating balance beam. Use balance beams to improve flatness, especially when laying bends. The balanced beam has a good filtering effect, which can avoid the influence of fixed reference lines and human errors.
Non contact electronic balance beam. Use laser or ultrasonic modes to measure and adjust elevations electronically to improve paving quality and flatness.
These methods for adjusting runway pavers each have their own advantages and disadvantages, and are suitable for different construction conditions and requirements. Friends can flexibly adjust the elevation method during the construction process.
