Tool-type pile cap device for high-frequency vibration of steel pipe pile

Abstract

The invention relates to a tool-type pile cap device for high-frequency vibration of a steel pipe pile. The tool-type pile cap device includes an upper part of a pile cap and a lower part of the pilecap. The lower part of the pile cap sleeves a reinforcing ring of the steel pipe pile closely, the lower part of the pile cap and two orthogonal holes reserved in the reinforcing ring of the steel pipe pile are buckled together through two bolt pins in cross, the heads of bolt pints are closely attached to the lower part of the pile cap, the tail parts of the bolt pins are fastened to the outer wall of the lower part of the pile cap through nuts and are locked by pin holes, and it is ensured that relative displacement is not generated between the pile cap device and the steel pipe pile when the steel pipe pile is hit in a high-frequency vibrating mode by a vibrating hammer. The tool-type pile cap device is easy to operate, the pile cap is closely attached to the steel pipe pile by using the bolt pins, the close reinforcement of the steel pipe pile is realized by using a pin bolt cross pin reinforcement method, and the deformation of the pile cap and of the steel pipe pile at the time of high-frequency pile sinking is reduced; and the pile sinking quality of the steel pipe pile is effectively ensured, while on-site construction time and material input are reduced, and the construction cost is saved.

Description

technical field [0001] The invention is a tool-type pile cap device for high-frequency vibration of steel pipe piles, in particular a pile cap device suitable for the construction of small-diameter steel pipe piles. Background technique [0002] At present, the minimum distance between conventional vibratory hammer clamps is 650mm, which can meet the requirements for embedding large-scale steel pipe piles. However, conventional clamps cannot be used for pile sinking in engineering parts that require high demand for small-size steel pipe piles such as ramp construction. The conventional method on site is to weld steel pipe piles that can meet the size of the fixture. This method requires manual climbing and welding. The construction is difficult and will also cause corresponding safety hazards. The effect is not ideal, which prolongs the construction period and increases labor input. It also increases the usage of on-site materials, which significantly increases the construct...

The conventional method on site is to weld steel pipe piles that can meet the size of the fixture. This method requires manual climbing and welding. The construction is difficult and will also cause corresponding safety hazards. The effect is not ideal, which prolongs the construction period and increases labor input. It also increases the amount of materials used on site, which significantly increases the construction cost
