The invention discloses a variable-stiffness semi-rigid structure construction method suitable for rebuilding and renewal projects, a variable-stiffness semi-rigid structure is constructed by combining various assemblies, the stiffness is adjustable, different engineering requirements and load conditions are met, in the construction stage, a lower cable structure provides overall stiffness, safety and stability are ensured, and after an upper steel member is closed, the lower cable structure is connected with a lower steel member. The lower cable structure and the lower cable structure jointly form an overall stress system, structural rigidity is enhanced, wind resistance and seismic resistance are improved, external loads are effectively dispersed, the service life is prolonged, and in a construction changing and renewing project, the scheme flexibly adjusts the structural rigidity, adapts to a complex construction environment, is coordinated with an original structure and guarantees the stability of a new structure. Standardized components and modular design are adopted, the construction efficiency and quality are improved, dependence on single components and skills of constructors is reduced, the construction difficulty and risk are reduced, the construction period is shortened, and the construction method has remarkable technical advantages and is suitable for various complex construction scenes.

The invention relates to the technical field of power system high-voltage switchgear control. The invention provides a GIS high-voltage circuit breaker emergency opening method and system based on three-phase linkage. The method comprises the following steps: collecting a direct-current control power supply state and a three-phase circuit breaker operation state signal, and judging a direct-current control power supply power loss and electrical opening failure fault through a fault recognition model; generating a three-phase cooperative opening instruction containing a synchronous time sequence and a power parameter based on a judgment result; the instruction is synchronously issued to an execution device, and the three-phase moving contact is driven to be synchronously opened; and a contact position signal after opening is collected for verification, and if the preset state is not reached, parameters are adjusted for re-driving until opening is completed and a signal is output. The problems that when a direct-current control power supply loses power, an existing GIS high-voltage circuit breaker depends on a single-phase independently-operated manual emergency opening device, so that opening is different, operation is tedious, and the emergency efficiency is low are solved.

This application provides a beamless direct-connection prefabricated energy storage cabin foundation structure, including multiple prefabricated piles, each prefabricated pile having an adjustable height seat at its upper end, a bottom frame at the lower end of the energy storage cabin, multiple connecting plates at the lower end of the bottom frame, and a base assembly at the lower end of each connecting plate. Each base assembly docks with each adjustable height seat, the adjustable height seat having a docking seat with an inner conical surface in the center of the docking seat, and the base assembly including a docking plate with an outer conical surface, the outer conical surface engaging with the inner conical surface. This solves the problems of complex structure, long force transmission path, long construction period, and difficulty in disassembly and assembly in traditional three-stage energy storage cabin foundation structures.
