Problems solved by technology

[0003] In view of the related technologies mentioned above, the inventor believes that when the steel casing is buried, if the pile foundation is deep and the length of the steel casing is not enough, it is necessary to weld multiple steel casings coaxially together, and the multiple steel casings must be welded together. After the tubes are welded together and then lowered, it is difficult to lower the steel tube because the steel tube is too long; manual spot welding is required for the tube to be lowered while welding, which is likely to cause the butt offset of the steel tube during welding, resulting in the steel tube after welding. The shell of the pile is skewed, which makes it very difficult to bury the steel casing of the deep pile foundation

Abstract

The invention relates to a deep pile foundation construction device and a construction method thereof, and belongs to the technical field of pile foundation construction. The deep pile foundation construction device comprises a rack, a positioning plate is arranged on the rack, a positioning hole allowing steel casings to be inserted is formed in the positioning plate, a positioning butt joint mechanism is arranged on the position, located above the positioning plate, of the rack, and the positioning butt joint mechanism is used for performing coaxial butt joint on the two steel casings; and a welding gun, an adjusting mechanism and a driving mechanism are further arranged on the positioning plate, the welding gun is used for welding the abutting position of the two steel casings, the adjusting mechanism is used for adjusting the height of the welding gun, and the driving mechanism is used for driving the welding gun to do circular motion around the steel casings. The deep pile foundation construction device has the effect of reducing the difficulty of embedding the steel casings in a deep pile foundation.

Description

technical field [0001] The present application relates to the field of pile foundation construction technology, in particular to a deep pile foundation construction device and a construction method thereof. Background technique [0002] Pile foundation is a deep foundation that connects the tops of several piles into a whole through caps to bear dynamic and static loads together. Pile is a vertical or inclined foundation component set in the soil, and its function is to pass through the weak high compression The soil layer or water transfers the load borne by the pile to the harder, denser or less compressible foundation bearing layer. We usually refer to the piles in the pile foundation as foundation piles. When constructing pile foundations, the steps of drilling positioning-embedding steel casing-drilling rig in place-punching construction-clearing holes-adjusting and placing reinforcement cages are generally carried out. [0003] In view of the related technologies ment...
