Description

A foundation compaction device with a buffer structure

Technical field

The utility model relates to the technical field of construction engineering, specifically a foundation compaction device with a buffer structure.

Background technique

Building foundations are divided into natural foundations and artificial foundations. Foundations that can directly bear the load of buildings without treatment are called natural foundations. On the contrary, foundations that need to be processed through foundation treatment technology are called artificial foundations. Today's building foundations are generally made of lime, soil and water mixed in proportion and tamped in layers. This is my country's traditional masonry method of brick and wood structures. In modern times, it is often used in conjunction with concrete structures to build low-rise residences, school buildings, offices, etc. architecture. Building foundations need to be compacted. If the compaction is not sufficient, the building ground will be prone to depressions in the later period. In severe cases, collapse accidents will occur, affecting the service life of the building and the safety of residents.

For example, the Chinese patent publication number is CN212801478U. The technical solution disclosed in the patent document is as follows: the foundation compaction equipment for construction projects is used to flatten uneven parts of the foundation and has the characteristics of simple operation and high efficiency. However, the existing compaction equipment used in construction projects does not have a buffer device, and the pressure plate is in direct contact with the foundation. The instant impact force generated by the direct contact can easily cause damage to the equipment, and the existing compaction equipment has poor structural strength and stability.

but:

In the above-mentioned patent, the foundation compaction device relies on springs to form a buffer layer. However, the buffer layer formed by springs alone is too thin, and there are too many springs. If a single spring is damaged, it cannot be judged whether the entire flattening device is level, resulting in the level of the flattening device. It cannot be guaranteed, and the flattening device cannot be moved, which makes the use of the flattening device more limited.
