1. It can adapt to different geological conditions. Construction is possible from clay and sand to gravel layers, as well as from Quaternary soft soils to hard rocks, at depths of over 50 cm. Construction can be carried out even in extremely complex geological conditions such as high groundwater levels or very soft silty clay layers, without the need for dewatering measures; thus, any impact of dewatering on nearby buildings can be avoided. 2. During construction, there is virtually no vibration or noise; the construction speed is fast, the depth of excavation can be great, and the precision of trench formation is high. 3. The construction clearance is small, allowing for efficient use of land. Since no slope stabilization is required during the construction of diaphragm walls, a distance of only 0.5 m or even 0.2 m is needed from adjacent buildings, allowing for the construction of underground projects and deep foundations in densely built areas with minimal impact on nearby buildings and road traffic. 4. High load-bearing capacity and great structural stiffness. Due to its integrity, impermeability, and durability, as well as its strength and stiffness that can meet various requirements, it has multiple functions. It can serve as part of the underground structural framework, helping to reduce the costs associated with retaining structures. It can be used in projects such as high-rise buildings, underground railways, underground storage areas, underground factories, water supply and drainage facilities, shafts, docks, locks, piers, and dams. 5. The equipment investment is high, and the construction technology is relatively complex. 6. A large amount of stabilizing fluid is required, slag and slurry removal are labor-intensive tasks, and environmental pollution is relatively severe.

1. High stiffness and large excavation depth; suitable for all soil types； 2. High strength, low deformation, good water resistance, and can also serve as part of the main structural framework ； 3. Can be used near buildings and structures, with minimal environmental impact ； 4. High cost.
