Arc-shaped double-clamp system required by high-frequency vibration of steel pipe pile

Abstract

The invention relates to an arc-shaped double-clamp system required by high-frequency vibration of a steel pipe pile. A cross beam is fixedly connected to a vibrating hammer through a bolt, two arc-shaped clamps are embedded into a cross beam slot and can move bidirectionally in the cross beam slot to adjust the separation distance for meeting the clamping demands of steel pipe piles with different diameters, the two arc-shaped clamps with the adjusted separation distance are fixedly connected to the cross beam through bolts, and the two arc-shaped clamps are in reinforced connection to through a steel connecting plate and a bolt, so that the adjusted arc-shaped double clamps do not generate displacement when the vibrating hammer vibrates at a high frequency. The system provided by the invention is simple to operate. As an arc-shaped fixed clamp piece and the steel pipe pile are tightly laminated, a hydraulic retractable clamp piece can move freely to clamp and loosen the steel pipe pile, and the double clamps are locked in relative positions through a limiting steel plate and the bolt, so that the mechanical deformation at the end port of the steel pipe pile during high-frequency pile sinking is greatly reduced, and therefore, the steel pipe pile butt joint quality is effectively ensured, and meanwhile, the field construction steps and labor force investment are reduced, and the construction cost is lowered.

Description

technical field [0001] The invention relates to an arc-shaped double clamp system for high-frequency vibration construction of steel pipe piles, in particular to a clamp system suitable for the construction of small-diameter steel pipe piles. Background technique [0002] At present, the conventional vibratory hammer clamp adopts the flat clamp, and it is not a big problem when setting steel casings and other measures that do not require high measures. The port is very easy to deform too much due to heat, clamps not tightly bonded, slack, etc., resulting in poor butt joint of the upper and lower section steel pipe piles, causing engineering hidden dangers. At the same time, there are no mature tools for pile mouth shaping of steel pipe piles available, and manual work is required For plastic surgery, the construction is very difficult and the effect is not ideal, which prolongs the construction period, increases labor input, and significantly increases the construction cost....
