Vibratory Hammer Device

Abstract

The invention discloses a vibratory hammer device which comprises shock excitation devices. The shock excitation devices are connected with a vibration reduction plate, a connection plate is arranged between the vibration reduction plate and the shock excitation devices, piles are vertically arranged on the lower surface of the vibration reduction plate and close to the two ends of the vibration reduction plate, the two piles are connected through a loading plate, the two ends of the loading plate penetrate through the piles and extend out of the piles, the tops of the two piles are connected with the vibration reduction plate, the bottoms of the two piles are connected to the upper surface of a hydraulic plate, and the piles are fixedly connected with the hydraulic plate; a connection mechanism is vertically arranged in the middle of the loading plate and movably connected with the loading plate, and the bottom of the connection mechanism is arranged on the upper surface of an auxiliary stress plate. The number of the shock excitation devices is two, one shock excitation device is arranged on the upper surface of the vibration reduction plate, and the other shock excitation device is arranged between the hydraulic plate and the auxiliary stress plate. The vibratory hammer device is good in stability and high in output efficiency, periodic exciting force generated by the shock excitation devices enables the piles to vibrate, soil around the piles is liquefied, friction of the soil on the piles is lowered, and the using effect is good.

Description

technical field [0001] The invention relates to a civil construction facility, in particular to a vibratory hammer device. Background technique [0002] Vibratory hammer is one of the important equipment in pile foundation construction. It is widely used in civil construction, and its purpose is to drive piles of buildings. When the vibratory hammer is working, the spring arranged on the vibratory hammer will move up and down, sometimes causing the horizontal displacement of the spring, which will damage the pile body, resulting in the need to replace the pile body, and then continue piling. Vibration pile sinking of prefabricated piles and pipes can greatly save construction costs. From the perspective of operation, it usually only needs to impact 10% of the pile sinking hammer. However, in some special cases, the vibration pile hammer may fail to make the pile under In addition, if the friction between the pile and the soil is too large, ordinary vibrating pile hammers ca...

Problems solved by technology

When the vibratory hammer is working, the spring arranged on the vibratory hammer will move up and down, sometimes causing the horizontal displacement of the spring, which will damage the pile body, resulting in the need to replace the pile body, and then continue piling. Vibration pile sinking of prefabricated piles and pipes can greatly save construction costs. From the perspective of operation, it usually only needs to impact 10% of the pile sinking hammer. However, in some special cases, the vibration pile hammer may fail to make the pile under In addition, if the friction between the pile and the soil is too large, ordinary vibrating pile hammers cannot penetrate the soil, which will affect the efficiency of piling and affect the progress of construction.
