A heavy hammer ramming device

Abstract

The invention relates to a heavy hammer ramming device, which effectively solves the problems of low hammer ramming efficiency and the inability to automatically correct ground deflection; the technical solution includes a combined hammer head, which includes a bottom block, a top block block and multiple middle blocks, the top block, bottom block and middle block are all columnar structures, the bottom block and each middle block are provided with stepped through holes, and a sphere is installed in each through hole, and the sphere can be Sliding and rotating in the through hole, the sphere is fixed on the lower end of the middle block or the top block above it, and the bottom of the combined hammer head is equipped with a plurality of vertical plates uniformly distributed around the circumference, and the vertical plates can rotate in one direction towards the center of the circle. The upper end of the block and the upper end of each middle block are provided with chamfers, and the lower ends of the top block and the middle block are concentrically provided with a ring-shaped convex edge. When the top block or the middle block slides down, the convex edge presses on the chamfer below. The present invention can realize multiple hammerings by one lifting, effectively improves the compaction efficiency, and can automatically realize the leveling of the inclined ground.

Description

technical field [0001] The invention relates to the field of roadbed construction, in particular to a heavy hammer ramming device. Background technique [0002] The heavy hammer compaction method refers to the ground treatment method that uses the impact energy generated when the heavy hammer falls freely from high altitude to make the soil layer in a certain depth under the ground reach a compact state; the current rammer is a single hammer head, which is lifted once to ram the ground. Once, the main time-consuming process of tamping is the lifting process of the hammer head, so the efficiency of the tamping operation is low and the construction period is long; moreover, the ground often has a deflection with one side high and the other side low during tamping, and the current hammer head cannot automatically correct the deflection. When the deflection is large, workers need to level it before tamping; in addition, in order to avoid the air layer under the hammer head from ...
