Description

Ground compaction device for civil engineering

technical field

Specifically, the invention relates to a ground compaction device for civil engineering, and relates to the field of ground compaction equipment.

Background technique

At present, in civil engineering infrastructure construction, it is generally necessary to use tamping equipment for tamping operations in the initial stage of construction in order to ensure the firmness and reliability of the foundation. The current tamping equipment generally uses a tamping machine for tamping operations. The tamping machine uses a tamping hammer to tamp up and down. The tamping hammer adopts a vertical drop method for tamping. The tamping force depends entirely on the weight and drop height of the tamping hammer. The height of the tamping hammer and the hammer is required to be relatively large, and for some civil engineering, this method is often difficult to implement due to space reasons, and the swing-beating hammer tamping with structures such as cams and connecting rods will produce a huge impact. The vibration of the tamping machine causes the side of the tamping machine away from the tamping hammer to need a heavier counterweight for counterweight, which makes the tamping machine relatively heavy and affects the tamping efficiency.
