Description

Technical Field

[0001] The utility model relates to the technical field of piling devices, and more specifically to a piling device for highway bridge construction. Background Art

[0002] The process of bridge construction according to the design content mainly refers to the bridge construction technology and construction quality. The spiral pile driver is a pile driving equipment that uses a power head to drive the drill rod and drill bit to drill holes underground. The spiral pile driver can be divided into two parts, the pile frame and the drilling part.

[0003] The shortcomings of the existing technology: Usually, the piling equipment first needs to be moved to the piling site and then the piling is carried out. However, the piling process may cause the pile frame to shake. The usual stabilization method is to insert steel nails into the soil to form a simple stable structure. However, this stabilization method is less effective and may cause the steel nails to loosen. It is not suitable for long-term piling operations, and it is also more troublesome to pull out the steel nails later. For this reason, we propose a piling device for highway bridge construction.

[0012] 1. The utility model supports the equipment on the ground through the action of the fixing seat, and then by rotating the threaded rod, the threaded rod will drive the threaded pin to rotate into the ground.
