Vibrating device and vibrating method of cast-in-place pile concrete

Abstract

The invention relates to a vibrating device and a vibrating method of cast-in-place pile concrete. The vibrating device comprises a vibrating ring, one or more motors, a positioning barrel, and one ormore vibrating sleeves, wherein the motors are arranged at the periphery of the vibrating ring in a circumferential direction; rotating shafts of the motors inwards penetrate through the vibrating ring in a radial direction of the vibrating ring; the positioning barrel is a hollow tube body and coaxially arranged in the center of the vibrating ring; the vibrating sleeves are connected between thepositioning barrel and the vibrating ring and internally provided with vibrating shafts; one end of each vibrating shaft is connected with each rotating shaft of the motor; an eccentric block is arranged at the other end of each vibrating shaft; and when the vibrating shafts rotate, the eccentric block continuously collide peripheral internal walls of the vibrating sleeves to further drive the vibrating ring to generate high-frequency vibration. A compaction pile foundation is filled with the concrete vibrated by the vibrating device of the cast-in-place pile concrete, and the grip of the concrete and a steel reinforcement cage is better. The pile body concrete is bonded with soil around the concrete more securely. A conduit vibrates by the action of the vibrating device; the flow of theconcrete in the conduit is accelerated; and a blocking phenomenon due to poor placeability of the concrete is avoided.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a concrete vibrating device for a cast-in-place pile and a vibrating method thereof. Background technique [0002] At present, concrete is an overall dense engineering composite material formed by combining aggregates with cementitious materials (cement). It has been widely used in basic construction fields such as construction engineering, bridge engineering, and traffic engineering. Under normal circumstances, the bored pile does not use the mechanical vibration filling method, that is, the dense concrete is used, but the concrete mixture will be mixed with a certain amount of air during the stirring, transportation, and pouring process, and the concrete will be mixed with the admixture after adding the admixture. Bubbles increase, and the internal porosity increases after the concrete solidifies and hardens. After coring the concrete of the bored pile, it is found that th...

Problems solved by technology

[0003] If the concrete is not dense, the section of the pile will be weakened and the bearing capacity will decrease.

Moreover, because the concrete is not dense, there are tiny holes and cracks, and the external moisture, salt and gas can easily invade the interior, corrode the steel bars, cause premature damage to the structure, and affect the life of the structure.

However, the current plug-in concrete vibrating device cannot effectively vibrate the concrete of the bored pile, so it is necessary to further improve the current concrete vibrating device to avoid the danger of uncompacted concrete vibration
