Drilling, pile splicing and pile planting all-in-one machine and construction method thereof

Abstract

The invention discloses a drilling, pile splicing and pile planting all-in-one machine and a construction method thereof. The drilling, pile splicing and pile planting all-in-one machine comprises a walking mechanism, a base plate, a plurality of hoisting devices and a rotary disc capable of rotating relative to the base plate. Operation pile position holes for drilling and pile planting are formed in the base plate; a tower which has a circular truss structure and is coaxial with the rotary disc is fixed on the rotary disc; a pipe pressing power head, a plurality of drilling power heads, a plurality of rotary welding devices for lengthening and welding upper and lower pipe piles and a pile feeding pipe driving head are sequentially arranged along the outer circumference of the tower; eachpipe pressing power head, each drilling power head, each rotary welding device and each pile feeding pipe driving head can be located over the corresponding operation pile position holes in sequenceafter rotating along with the rotary disc of a rotary disc device; and pile pressing equipment driven by an oil cylinder for pile planting is mounted on the base plate through a guide rail. Accordingto the drilling, pile splicing and pile planting all-in-one machine, drilling, pile splicing and pile planting construction can be completed on one device, the height of the device is relatively low,the concentricity of devices with multiple functions on the rotary disc is good, and the stability of the device is high.

Description

technical field

[0001] The invention relates to the technical field of building pile foundation construction, in particular to an integrated machine for drilling, connecting and planting piles and a construction method thereof. Background technique

[0002] In the field of building pile foundation construction technology, foundation piles such as prefabricated pipe piles are implanted into the soil. The traditional construction method is a single pile machine operation, and a drilling rig is used for drilling. Hammer drilling rigs work in turns; for pile planting, the pile driver can only press piles, and if hammer piles are needed, vibratory hammers are also used; The construction of a pile position can only be completed by the supporting use of multiple pile machines with different functions. Cross construction is likely to cause deviation of pile positions, the site required for construction is large, the construction process is intermittent, and the construction efficien...
