Recently, with the continuous deepening of urban underground space development and utilization, underground passages, as important infrastructure connecting urban commercial districts, transportation hubs, and residential areas, play an increasingly important role in alleviating surface traffic pressure, improving urban traffic efficiency, and enhancing urban functions.

Recently, with the continuous advancement of water conservancy engineering construction, various water conservancy facilities such as reservoirs, dams, channels, and pump stations play an important role in flood control, irrigation, water supply, power generation, and other aspects. As the core link of hydraulic engineering construction, anti-seepage and leakage prevention are directly related to the safety, stability, service life, and operational efficiency of the project.

Recently, with the continuous improvement of urban fine management level, municipal pipelines, as the "underground network" of the city, undertake important functions such as water supply, drainage, gas, and communication.

Recently, with the continuous acceleration of urban infrastructure construction, various infrastructure projects such as roads, bridges, municipal pipelines, and industrial plants have been steadily advancing. As the core bearing part of building infrastructure, the stability and bearing capacity of the foundation directly affect the construction quality, structural safety, and service life of the entire project. However, in the actual construction process, many project sites have problems such as insufficient foundation bearing capacity, excessive settlement, and uneven soil layers. If not treated scientifically, it can easily lead to safety hazards such as building cracking, deformation, and even collapse.

Recently, with the continuous promotion of urban ecological construction, landscaping projects have become an important carrier for improving urban livability and ecological environment. As the core foundation for the growth of landscaping plants, the quality of soil directly affects the survival rate, growth, and landscape effect of plants. However, many current landscaping projects have problems such as soil compaction, pH imbalance, nutrient deficiency, and poor air permeability on site, which seriously restrict the quality of greening engineering.

Recently, with the transformation of urban construction towards high efficiency and green, steel structure engineering has been widely used in various engineering projects such as large venues, high-rise buildings, industrial parks, etc., relying on its advantages of lightweight and high strength, convenient construction, energy conservation and environmental protection. The construction quality of steel structure engineering is directly related to the safety, stability, and durability of buildings, and a scientifically standardized construction process is the core prerequisite for ensuring engineering quality.
