Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, and in particular to a drilling and drilling equipment for piling in construction. Background Art

[0002] In the field of construction, especially in foundation engineering, piling is a key step in building a stable foundation structure. Traditional drilling and perforating equipment uses a rotating drill rod to drill soil or rock to create holes for placing pile foundations. However, under some geological conditions, such as soft soil, sandy soil or the presence of groundwater, the hole wall may become unstable after drilling, increasing the risk of hole collapse. Once collapse occurs, not only does it need to be re-drilled, which increases construction costs and time, but it may also pose a threat to the safety of the construction site.

[0003] Traditionally, in order to prevent the hole from collapsing, a casing (conduit) is usually installed in advance, that is, a casing made of steel or other materials is pressed into the ground during the drilling process to keep the hole wall stable. However, this method also has its limitations: for example, the use of casings adds additional costs and workload, and in some cases, due to complex geological conditions, the casing is difficult to insert smoothly, or when it is pulled out, it will disturb the surrounding soil, which will affect the stability of the hole wall.
