Background

At present, in the construction process of transmission and transformation line engineering, when the foundation of a power line tower is built, a larger foundation pit needs to be excavated, and a base and a support column need to be installed in the foundation pit and concrete needs to be poured. Usually the support is located near the very center of the pit, and the height of the support is level with or slightly above the ground. In the construction process, the vibration rod is manually operated, and the levelness and the height are manually measured at the position of the strut, namely the center suspension position of the foundation pit. Constructors often need to set up higher scaffolds.

When the base and the support pillar need to be poured with concrete at the same time, the rooting points of the scaffold are not arranged, and the scaffold cannot be erected. Thus, concrete vibration defoaming and related measurement work of the strut will not be performed. Under the existing construction technology, the base can only be poured with concrete and cured, the base is used as a scaffold rooting point, a scaffold is erected on the base, and then other work of the foundation pit center pillar is completed. Therefore, a safe operation platform for construction on a foundation pit is needed to solve the problem of suspended operation in the center of the foundation pit.

At present, a construction mode is to pour a pillar and a base in two steps and erect a scaffold, so that the construction period is long, the operation steps are complicated, the construction period is not favorable to be saved, and more potential safety hazards exist.
