However, in the actual construction process, the verticality accuracy and direction angle of the lattice column cannot be accurately controlled, and the lattice column is prone to excessive verticality deviation and excessive torsion angle. Large verticality deviation and excessive torsion angle of the lattice column will greatly reduce the force performance of the lattice column, affect the stability of the foundation pit, and also increase the construction difficulty of the reinforced concrete support beam.
