Abstract

The invention provides an auxiliary device for hitting an ultralong steel pipe pile and an application method thereof and belongs to the technical field of civil engineering machinery. The auxiliary device for hitting the ultralong steel pipe pile comprises a base, a lower wellhead mechanism and an upper wellhead mechanism, wherein the lower wellhead mechanism is detachably connected to the base;a center clamping space of the lower wellhead mechanism is adjustable; the upper wellhead mechanism is connected to the lower wellhead mechanism; a center clamping space of the upper wellhead mechanism is adjustable; and the lower wellhead mechanism and the upper wellhead mechanism with adjustable center clamping spaces are used for clamping the ultralong steel pipe pile. According to the auxiliary device for hitting the ultralong steel pipe pile provided by the invention, telescopic components of the center clamping spaces inside the two wellhead mechanisms are simultaneously adjusted to clamp the steel pipe pile; subsequently the steel pipe pile is hit; the perpendicularity of the steel pipe pile is guaranteed; the auxiliary device is also applicable to steel pipe piles different in diameter; and the friction resistance between the telescopic components and the steel pipe pile is reduced as well.

Description

technical field [0001] The invention belongs to the technical field of civil engineering machinery, and in particular relates to a driving auxiliary device capable of maintaining the verticality of super-long steel pipe piles and a usage method thereof capable of continuous operation. Background technique [0002] The ultra-long steel pipe pile is a commonly used enclosure structure for underwater deep foundation pit excavation construction, and the verticality control of its construction is a major difficulty. The traditional verticality control of steel pipe piles is carried out by hanging the vertical line, the operation process is cumbersome, and the verticality control of steel pipe piles is not accurate. Contents of the invention [0003] In view of this, the object of the present invention is to provide an auxiliary device for driving super-long steel pipe piles, so as to solve the problem of using the method of hanging vertical lines in the prior art. The operation...
