Drilling pile connecting and planting integrated machine and its construction method

Abstract

The invention discloses an integrated machine for drilling, connecting piles and planting piles and a construction method thereof, which comprises a traveling mechanism, a chassis, a plurality of hoisting equipment, and a turntable capable of rotating relative to the chassis; on the chassis are working piles for drilling and planting piles. Position holes; a tower with a circular truss structure coaxial with the turntable is fixed on the turntable; along the outer circumference of the tower, a pressure tube power head, multiple drilling power heads, multiple extensions and welding up and down are arranged in sequence A rotary welding device for pipe piles, a driving head for sending pile pipes; after each pipe pressing power head, each drilling power head, each rotary welding device and each pile feeding pipe driving head rotate with the turntable of the turntable device, All can be located directly above the operation pile hole; a pile pressing device driven by an oil cylinder for pile planting is installed on the chassis through guide rails. The machine and the method can complete the drilling, pile connection and pile planting construction on one piece of equipment, and the equipment height is relatively low, the concentricity of the multifunctional device on the turntable is good, and the equipment stability 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...

AI Technical Summary

Problems solved by technology

But still there are following deficiencies in above pile driver: 1, need to drill the deeper hole such as the hole of about 75 meters, need to plant the longer pipe pile such as the 60 meter long pipe pile, require the height of single column too high, add Multiple columns have different heights and are scattered on the turntable, objectively there are potential safety hazards such as unstable center of gravity

2. During the actual construction, only one kind of construction can be carried out at the same time, and the welding of the piles, that is, the upper and lower pipe piles, needs to be welded by another equipment and hoisted to the pile planting equipment. It is still difficult to construct in a narrow site, and the continuity of construction , progress and construction efficiency are still unsatisfactory

3. It is difficult to control mud spillage after drilling, and it is difficult to keep the site dry and flat
