The application discloses a steel cross-bracing
axial force system for controlling deformation of a foundation pit lattice column and a construction method, relates to the technical field of deep foundation pit construction, and discloses a steel cross-bracing
axial force system for controlling deformation of a foundation pit lattice column, which comprises a foundation pit
enclosure structure, a lattice column and a steel cross-bracing
servo axial force system. The lattice column comprises angle steels and patch plates. The steel cross-bracing
servo axial force system comprises a steel sleeve box, a plug-in steel cross-bracing, a
deformation monitoring sensor, a
monitoring system and a hydraulic jack. The application has good
deformation control effect and high precision, can prevent the weakening of vertical stress capacity caused by the deformation of the lattice column, ensures the stability of the foundation pit, and guarantees the safety of the foundation pit construction.
