Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] The piling method of the spiral steel pile of the present invention is to punch out a deep hole equivalent to the buried depth of the spiral steel pile with a hole puncher 1, and then screw the spiral steel pile into the above-mentioned deep hole with a pile placing machine 2 . Since the bottom of the drilling machine and the pile driver are provided with wheels, they can move within a certain range so as to drive multiple spiral steel piles within a certain range. According to the different terrain and geological conditions, two guide rails can also be prepared, and the drilling machine or pile laying machine can be erected on the guide rails to perform operations and move on the guide rails.

[0026] see Figure 1 to Figure 4 , punching machine 1 among the present invention comprises pedestal 11, motor 12, hoist 13, pulley 14, stee...

Abstract

A piling method of a spiral steel pile includes that firstly a deep hole equal to burial depth of the spiral steel pile is punched through a punch, and then the spiral steel pile is screwed into the deep hole through an offsetting machine. The punch comprises a base frame, a motor, a winch, a pulley, a steel wire rope, a heavy hammer and a punching rod. The offsetting machine comprises a machine frame, a hydraulic motor, a hydraulic pump, two hydraulic columns, a sliding plate assembly, a rotary pile motor, an automobile stirring shaft, a geneva wheel, a bidirectional hydraulic jack and a hydraulic adjusting rod. During punching, the punching rod is arranged below the heavy hammer and is hit into earth through free falling of the heavy hammer. During offsetting, the spiral steel pile is connected on the lower surface of the geneva wheel, and the rotary pile motor and the hydraulic motor drive the geneva wheel to rotate horizontally and simultaneously move downwards so as to screw the spiral steel pile into the deep hole. The piling method can prevent the spiral steel pile from being damaged by stones or hard objects in the punching process, reduces damage probability of the steel pile, and is suitable for operating in various environments and geological conditions.

Description

technical field [0001] The invention relates to a construction method, in particular to a pile driving method of a spiral steel pile. Background technique [0002] At present, with the rapid development of the economy, the reserves of non-renewable energy such as oil and coal are becoming less and less, energy and environmental problems are becoming more and more prominent, and the development and utilization of renewable energy have attracted more and more attention. As one of the important clean energy sources, the current technology research and technology development using solar energy is developing rapidly all over the world. Equipment such as solar water heaters, solar cells, and solar cookers have been widely used. Solar photovoltaic power generation is one of the important technologies. However, the cost of solar photovoltaic power generation is relatively high. In addition to the high price of solar photovoltaic panels, the foundation of solar photovoltaic is also...
