Background
In the concrete pouring process, in order to prevent the concrete from phenomena of void, unevenness, cellular pitted surface, incompact and the like, the concrete must be vibrated by a vibrating device in the pouring process.
When a large formwork is used to cast a concrete structure with a certain thickness in a closed manner (such as secondary lining casting in a tunnel), an attached slab vibrator is generally installed on the formwork to vibrate concrete attached to the surface of the formwork and a hand-held vibrating rod is generally used to vibrate the concrete deeply through a window formed in the formwork. Due to the limited excitation depth of the attached flat plate vibrator, the excitation depth of the handheld vibrating rod is enough, but the excitation range is limited, so that effective deep vibration is not carried out in many places (such as vault positions).
