Description

TECHNICAL FIELD

[0001] The present application relates to the field of geodetic engineering surveying, in particular to a continuous GNSS antenna support system suitable for various geological conditions. BACKGROUND

[0002] At present, most of the traditional geodetic continuous GNSS antenna support systems in China are based on steel bars and cement piles, which have the following disadvantages in the construction and use process: (1) The traditional one-dimensional steel-cement support system and the thermal expansion and contraction and cracking of cement increase the instability factors of the GNSS antenna.

[0003] (2) During the construction of the support system, strict requirements are placed on the geological conditions, such as the bedrock area can better meet the station construction requirements; while in the area covered by thick quaternary sediments, it is necessary to dig through the sediments to the bedrock to ensure the stability of the GNSS antenna, thereby consuming a large amount of manpower and material resources.

[0004] (3) After the construction of the support system, the antenna cannot be installed until the cement is solidified, which will lose a large amount of post-seismic deformation data.

[0005] (4) The magnetism of the metal materials used will affect the satellite signals received by the GNSS antenna.

[0006] Based on the above problems, it is necessary to design a three-dimensional steel support system for a more stable geodetic continuous GNSS antenna suitable for various geological conditions. SUMMARY
