Background

When the concrete mixed by the concrete mixer is used for pouring the member, air bubbles in the concrete must be removed, and tamping is carried out to ensure that the concrete is tightly combined, so that the phenomena of honeycomb pitted surface and the like of the concrete are eliminated, the strength of the concrete is improved, and the quality of the concrete member is ensured. The concrete is vibrated in the process of eliminating air bubbles and tamping the concrete. Classified by the method of transmitting vibrations: there are three kinds of internal vibrator, external vibrator and surface vibrator; according to the power source of the vibrator: there are three types of electric, internal combustion and pneumatic, and the electric application is the widest; classifying according to the principle that the vibrator generates vibration: there are both eccentric and planetary. The eccentric vibrating rod is characterized in that an eccentric vibrating system is arranged in the eccentric vibrating rod, and the eccentric vibrating rod rotates at a high speed under the driving of a motor or compressed air to generate unbalanced centrifugal force to drive a rod head to perform high-frequency micro-amplitude circumferential vibration.

The use of an insertion vibrating rod is to insert quickly and pull slowly: the quick insertion is to prevent the surface concrete from being compacted firstly and from layering and segregation with the lower layer concrete; the slow pulling is to make the concrete to fill the space formed when the vibrating rod is pulled out.

The plug-in vibrating rod is generally manually controlled, when the vibrating rod is pulled out manually, the slow pulling rate of the vibrating rod is difficult to control reasonably, the high strength is consumed, and the vibrating rod is difficult to pull out at a uniform slow pulling rate, so that the condition that the concrete filling space is not compact is easily caused.
