With the advancement of high-speed and heavy-duty rail transit and railway network construction in China, the accuracy of track laying has become a core element that determines the quality of track engineering, the safety and comfort of train operation, and directly affects the durability and operational stability of track structures.

With the continuous improvement of China's highway network construction, asphalt pavement is widely used in various transportation projects such as highways, urban main roads, rural roads, etc., due to its advantages of smoothness, comfort, wear resistance, skid resistance, and convenient construction.

Recently, with the continuous promotion of highway, railway, and urban bridge construction in China, prestressed tensioning construction, as the core key process of bridge structure construction, directly affects the bearing capacity, stability, and durability of bridges.

Recently, with the continuous improvement of urban infrastructure construction in China, underground passages have become an important carrier for alleviating surface traffic pressure and connecting urban functional areas.

Recently, with the continuous promotion of water conservancy infrastructure construction in China, water conservancy dams, as the core project of flood control and disaster reduction and water resource allocation, are widely distributed in rivers, lakes, reservoirs and other regions, and their stability and disaster resistance capability are directly related to the safety of life and property of people along the coast, ecological environment security and regional economic development.

Recently, with the continuous promotion of industrial production and urban infrastructure construction in China, pressure pipelines, as the core equipment for transporting gases, liquids and other media, have been widely used in various fields such as petrochemicals, heating and water supply, and energy transportation. The installation and pressure testing quality of pressure pipelines are directly related to the safety and stability of medium transportation. If the installation is not standardized and the pressure testing is not in place, safety hazards such as medium leakage and pipeline damage may occur. In severe cases, it may cause safety accidents such as fires and explosions, threatening the safety of personnel and property.
