Abstract

The invention discloses a high-efficiency pulling-out device for underwater steel pipe piles. The high-efficiency pulling-out device for the underwater steel pipe piles comprises a flush deck barge platform, a power system and a pulling-out assembly; a U-shaped groove is formed in the head of the flush deck barge platform; the power system comprises a winding engine arranged at the tail of the flush deck barge platform and a diesel generator which continuously supplies power for the winding engine; and the pulling-out assembly comprises a mechanical arm, a pulley block, a hydraulic system, a steel wire rope , a vibrating hammer and hydraulic tongs, the bottom end of the mechanical arm is connected to the tail of the flush deck barge platform in a hinged manner while the top can verticallyswing above the U-shaped groove, the pulley block is arranged at the top end of the mechanical arm, the hydraulic system is used for the mechanical arm to swing vertically, the steel wire rope penetrates through the pulley block and the winding engine and is connected with the vibrating hammer hoisted at the top end of the mechanical arm, and the hydraulic tongs are arranged at the bottom end of the vibrating hammer. The device can flexibly move on the water surface, is convenient to operate and high in use safety, and can effectively pull out the underwater steel pipe piles.

Description

technical field [0001] The invention relates to the technical field of municipal bridge construction, in particular to an efficient removal device for underwater steel pipe piles. Background technique [0002] The beam-column support method is a commonly used support construction method in the construction of cast-in-place box girders. The specific construction method is to first set up steel pipe piles, then vertically arrange I-beams, set up Bailey beams and distribution beams, and then carry out subsequent formwork construction. The beam-column support method is especially suitable for the construction of cast-in-place box girders under conditions such as crossing roads, mountains, rivers, etc. where full supports cannot be erected and the foundation treatment is difficult. It has the advantages of short construction period, good support stability, and economical savings. [0003] The beam-column support needs to be dismantled after the bridge construction is completed. ...
