Description

Technical Field

[0001] The present invention relates to the technical field of airport runway construction in polar environments, and particularly to a construction system and construction method for polar ice-concrete aircraft runways. Background Art

[0002] In polar environments, especially in the Antarctic region, the construction of airport runways faces great challenges. Currently, the construction of polar aircraft runways mainly relies on traditional ice and snow compaction or artificial modification of snow layer techniques, and these methods have many deficiencies. Since the blue ice areas in Antarctica are extremely rare, accounting for no more than 1% of the ice sheet surface area, and the number of blue ice airport runways that have been built and put into use is limited, it is particularly important to find alternative runway construction solutions. At the same time, most of the ice and snow runways already built in the Antarctic region are sled runways, and their construction techniques are limited to simple leveling and compaction treatments. Although they are relatively easy to build and have low costs, due to the insufficient hardness of the surface snow layer, they can only take off and land small sled-type aircraft, and such runways cannot meet the takeoff and landing requirements of large aircraft. In addition, although countries such as the United States and Russia have developed artificial snow surface modification techniques and built artificial modified snow layer runways, this technology is highly difficult and the construction cost is also relatively high. At the same time, in terms of the design and construction of large blue ice airports or large compacted snow layer runways in China, whether it is design parameters, technical means, or special construction equipment, it is basically blank.

[0003] To solve the above problems, the applicant has developed an ice-concrete material prepared from an ice-based composite cementitious material, coarse and fine aggregates, fiber reinforcing materials, and solution modifiers in a certain mixing ratio. This material has the advantages of high strength, high stability, and low cost, and is particularly suitable for the construction of aircraft runways in polar environments. However, the construction of ice-concrete materials requires special devices and processes to ensure that it can be evenly and quickly laid in the runway area and reach the required strength in a short time.

[0004] Therefore, in order to enable the takeoff and landing of large wheeled transport aircraft, it is urgent to develop a new construction system and construction method for polar ice-concrete aircraft runways. Summary of the Invention
