Scope

Main technical content: At present, the problems encountered in the use of axial force self-compensating steel supports in China include: 1. Different types of axial force self-compensating support systems are used in the industry, with varying results. There are single-control axial force systems and dual-control axial force/displacement systems, but there are no basic standards for equipment. 2. Lack of design standards, with no clear requirements for applied axial force values, equipment, and supporting facilities such as steel supports and embedded parts. 3. No reference standards for equipment operation, with a lack of construction standards for axial force control, displacement monitoring, data analysis, and equipment maintenance. Therefore, through research, it is necessary to provide unified technical standards and control points for axial force self-compensating steel supports, standardize construction techniques in the industry, and control deformation in foundation pit projects. It is also important to regulate the construction behavior of pre-stressed self-compensating steel supports and ensure their safety and effectiveness. The Technical Regulations for Axial Force Automatic Compensating Steel Supports summarize current construction experience and research results, providing systematic regulations and guidance for product equipment and construction operations. The regulations include: 1. General Provisions; 2. Terminology; 3. Basic Requirements; 4. Design; 5. Materials and Tools; 6. Site Implementation; 7. Inspection and Maintenance; 8. Safety Management. In terms of design, the regulations specify that the design plan should provide the axial force design calculation values, maximum and minimum alarm values for axial force, and ultimate bearing capacity values. It also defines the upper limit of applied axial force and control requirements. In terms of design and construction, the regulations stipulate the system's layou
