Foundation tamping device for building

Abstract

The invention discloses a foundation tamping device for a building. The foundation tamping device comprises a movable bottom plate; the middles of the two sides of the movable bottom plate are connected with one ends of a U-shaped push handle correspondingly, and the middle of the movable bottom plate is provided with a through tamping groove opening; a fixed plate is fixedly installed on the movable bottom plate through a bracket, a first air cylinder is installed at the center of the fixed plate, and a piston rod of the first air cylinder is arranged downwards in the vertical direction and fixedly connected with a tamping plate; the positions, located on the two sides of the tamping groove opening, of the movable bottom plate are symmetrically provided with movable guide rails in the length direction, the two movable guide rails are both provided with movable bases, and second air cylinders are fixedly installed on the movable bases. According to the foundation tamping device, in thetamping process, when too much soil adheres to the tamping plate, a soil scraping plate abuts against the bottom face of the tamping plate through the second air cylinders, the movable bases drive the soil scraping plate to move along the bottom face of the tamping plate, the soil on the tamping plate is scraped off, the work efficiency of the tamping device is improved, and the workload of manpower is decreased.

Description

Technical field [0001] The invention relates to the field of construction technology, in particular to a foundation compaction device for construction. Background technique [0002] Foundation refers to the soil or rock mass supporting the foundation under the building. The soil layer as the foundation of the building is divided into rock, gravel soil, sand, silt, cohesive soil and artificial fill. There are two types of foundation: natural foundation and artificial foundation (composite foundation). The natural foundation is a natural soil layer that does not require reinforcement by humans. Artificial foundations need to be reinforced by humans, such as stone chip cushions, sand cushions, mixed lime soil backfilling and compaction. From the perspective of on-site construction, foundations can be divided into natural foundations and artificial foundations. The foundation is the pressure-bearing rock and soil bearing layer below the foundation. The natural foundation is a na...

Problems solved by technology

[0003] When the building is being built, the foundation needs to be excavated first. After the foundation is excavated, the foundation must be compacted to improve the stability of the subsequent building construction. A large amount of soil is often attached to the side where the ground contacts, and the soil layer accumulates thicker and thicker, resulting in an uneven bottom surface of the tamping plate, which cannot play a role in compaction. It is necessary to manually clean the ground of the tamping slab at regular intervals, which leads to the tamping device The work efficiency is low, which increases the amount of manual labor. For this reason, we have designed a construction foundation compaction device to solve the above problems
