The skirting board on the fence of the foundation pit can be painted with black-yellow or white-red paint, which can effectively warn pedestrians or vehicles around it. It can prevent debris from falling into the foundation pit. Because the mesh of the fence pit fence is small, this can prevent some debris from falling into the foundation pit, and prevent accidents caused by the construction workers below due to the debris falling. When the foundation pit fence is used to protect the building from the side, it can effectively prevent the danger of personnel falling.
