Recently, with the continuous deepening of urban ecological construction, landscaping has become an important measure to enhance urban livability, beautify the urban environment, and improve ecological quality. As the core carrier of landscaping projects, the planting quality and later maintenance level of garden seedlings directly affect the shaping effect, survival rate, and long-term stability of the green landscape.

Recently, with the transformation of China's construction industry towards green and industrialization, steel structures have been widely used in various projects such as large venues, high-rise buildings, bridge engineering, industrial parks, etc. due to their advantages of lightweight and high strength, convenient construction, energy conservation and environmental protection. Welding, as the core process of steel structure connection, has a direct impact on the overall integrity, bearing capacity, and durability of the steel structure. Poor welding quality can easily lead to safety hazards such as weld cracking and structural deformation, seriously affecting the service life and operational safety of the project.

Recently, with the continuous acceleration of railway construction in China, the networks of conventional and high-speed railways have been continuously improved. As the core load-bearing structure of railway lines, the roadbed directly affects the safety, stability, and comfort of railway operation. The railway subgrade is subjected to the repeated effects of train loads for a long time, and is also affected by natural factors such as precipitation, groundwater, and geological conditions, which can easily lead to subgrade settlement, slope collapse, erosion and other diseases.

Recently, with the rapid advancement of China's rail transit construction, shield tunneling technology has become the core method for underground tunnel construction in urban rail transit due to its characteristics of minimal environmental interference, high construction efficiency, and strong adaptability.

Recently, with the continuous improvement of China's highway transportation network, highway engineering construction is steadily advancing towards high quality and long service life. As the foundation of highway structure, the roadbed directly carries the vehicle load transmitted from the road surface, and its compaction quality is directly related to the smoothness, stability, and service life of the highway. As a core indicator for measuring the quality of roadbed compaction, if the compaction degree does not meet the standard, it is easy to cause roadbed settlement, pavement cracking, rutting and other diseases, which affect the safety and comfort of highway traffic and increase the cost of later maintenance.

Recently, with the continuous promotion of transportation infrastructure construction in China, bridge engineering, as the core hub connecting urban and rural areas and connecting the road network, directly affects the construction quality of traffic operation safety, engineering service life, and public travel guarantee.
