Description

Shallow well digging device for building foundation excavation

Technical Field

The invention relates to a shallow well digging device, in particular to a shallow well digging device for building foundation digging.

Background

The foundation refers to the portion of the soil body that is subjected to the load of the superstructure. The soil or rock mass under the foundation that bears the entire load of the building is called the foundation. The foundation does not belong to the building component, but has a very important role in ensuring the firmness and durability of the building. Is a part of the earth.

The foundation refers to the soil or rock mass of the supporting foundation under the building. Is not part of the building, but has a very important role in ensuring the firmness and durability of the building. The foundation includes natural foundation and artificial foundation. Natural foundations are layers of natural soil that do not require human reinforcement. The artificial foundation needs reinforcement treatment by people, and a stone chip cushion layer, a sand cushion layer, mixed lime-soil backfill, tamping and the like are common.

From the point of view of field construction, the foundation can be divided into natural foundation and artificial foundation. The foundation is the bearing rock-soil bearing layer under the foundation. The natural foundation can meet the requirement of bearing all loads of the foundation in a natural state, a natural soil layer reinforced by people is not needed, the engineering cost is saved, and the foundation does not need manual treatment. Natural foundation soils fall into four major categories: rock, gravel soil, sandy soil and cohesive soil. Artificial foundation: artificially treated or improved foundation. When the geological condition of the soil layer is better and the bearing capacity is stronger, a natural foundation can be adopted; under the condition of poor geological conditions, such as sloping fields, sandy fields or silt geology, or when the texture of the soil layer is good but the upper load is too large, in order to ensure that the foundation has enough bearing capacity, the foundation is artificially reinforced, namely the artificial foundation.

Building safety has always all been the important index of building, so there is the foundation of difference to the building of difference, the higher building of some floors just needs very deep foundation, so need dig the foundation well, but dig the foundation well in a lot of places now and all still the workman take the hoe to dig slowly, still can have the stone layer when digging to deeper, just at this moment just can only be dug with the chisel, do so not only the speed of digging slow, and extravagant a large amount of manpower and materials still, consequently need a quick building dig the foundation with digging shallow well device.
