Description

Technical Field

[0001] The utility model belongs to the technical field of steel cage installation equipment, in particular to a hydraulic vibration cage lowering device for reversely inserting a steel cage of a bored and grouted pile. Background Art

[0002] Concrete piles are generally formed in the foundation according to the design requirements, and then concrete is poured into the hole to form a concrete pile or a steel cage is placed to form a reinforced concrete pile. According to the hole-forming process, it can be divided into pipe-sinking cast-in-place piles and drilling, digging, and punching cast-in-place piles. The former is to drive a steel pipe with a pile tip into the soil, put in a steel cage, pour concrete, and pull out the steel pipe to form a cast-in-place pile. The diameter is generally 300~500mm and the length does not exceed 25m. The latter is to directly use drilling, digging, and punching machinery to form a hole and then pour concrete in the hole or put in a steel cage and pour concrete. The diameter is generally 300~400mm, the maximum can be more than 600mm, and the depth can reach tens of meters. If the bottom of the pile hole is exploded by machinery or explosives or poured, the steel cage is tamped with a hanging hammer in the sunken steel pipe. In the construction of cast-in-place piles, a steel cage vibrator is required to apply force to the steel cage and vibrate it downward.

[0003] The currently used reverse-insertion steel cage vibration device uses a flat vibrator connected to a long steel pipe, and the bottom of the steel pipe is flush with the bottom of the steel cage. The disadvantages of this device are: the vibration force provided by the top is transmitted to the bottom of the steel cage through the long steel pipe, which has a large reduction, poor force effect, and slow speed of lowering the steel cage. Therefore, a bored and grouted pile reverse-insertion steel cage hydraulic vibration cage lowering device is needed. By adjusting the vibrator from the top of the steel cage to the bottom of the steel cage, the force is direct, the reduction is small, and the steel cage lowering speed is fast. At the same time, through the internal support structure on the outside of the vibrator, the vibrator can be centered and vertically separated from the inner cavity of the steel cage, thereby ensuring the verticality of the hammer head when applying force to the bottom of the steel cage, thereby improving the downward movement efficiency of the steel cage.
