Description

A tamping device for underground foundation construction

Technical field

The utility model belongs to the technical field of building construction, and specifically relates to a tamping device for underground foundation construction.

Background technique

The foundation refers to the soil or rock mass beneath the building that supports the foundation. The soil layer used as a building foundation is divided into rock, gravel soil, sand, silt, clay soil and artificial fill soil. There are two types of foundations: natural foundation and artificial foundation (composite foundation). A natural foundation is a natural soil layer that does not require human reinforcement. Artificial foundations need to be reinforced by people, and common methods include stone chip cushion, sand cushion, mixed lime soil backfill and then compaction, etc.

The public authorization number "218027604U" discloses a foundation compaction equipment, which includes a base plate. Four rollers are connected to the bottom of the base plate. Two support plates are fixedly welded to the upper end of the base plate. The support plates on one side are bolted. For the motor, a horizontal plate is fixedly welded to the support plate on one side, a proximity switch is installed on one end of the horizontal plate, and the output end of the motor is connected to the winding wheel. This utility model has two sets of limiting screws on the ramming base block to limit the installation of multiple counterweight blocks, increase the overall weight of the ramming base block, and adjust and compact soils of different geology. The two side plate bolts on the bottom plate Install the adjustment plate. The adjustment plate can adjust the installation height, thereby adjusting the pressing force on the spring at the bottom. The ramming base block uses the spring rod to limit the spring. During the vertical movement of the ramming base block, the spring is compressed and the ramming is released. When ramming the base block, the ramming base block can be accelerated to increase the tamping strength of the ramming base block.

The above-mentioned new ramming base block uses a spring rod to limit the spring. When the ramming base block moves vertically upward, the spring is compressed.
