Background

The pile foundation engineering is used as a subsection engineering, plays a crucial part in the whole engineering construction, and determines the safety performance of the building. According to the occupied area of the building, the planned height of the building and the geological condition, the design unit performs scheme comparison and selection to finally obtain the design depth of the pile foundation, and further, different stratum through which the pile foundation passes are determined, such as: clay layer, sand layer, soft rock or hard rock etc., adopt heavy-calibre to dig the rig soon to carry out the drilling to get soil to pile foundation place position, reach pile foundation design degree of depth, this stage is simply referred to as "pore-forming" stage, this stage is accomplished smoothly, marks and can carry out "grout" stage.

In pile foundation engineering, since the shaft of a bored pile passes through various strata, the bored pile has a clay layer with high cohesive force and a sand layer with lower cohesive force. To improve the hole forming efficiency, the method mainly starts from the two aspects of 'collection' and 'taking'. By "harvesting" is meant that rotation of the drill barrel into the ground collects soil and inside the drill barrel and lifts it to the surface. The 'taking' means that the soil body in the drilling barrel can be smoothly taken out and piled on the ground so as to be convenient for carrying out next rotary digging and collecting.

The Chinese utility model patent application number is as follows: CN201220740502.4, the patent name is a bored concrete pile spiral pore-forming machine, and soil on the drilling tool can be removed by lifting the drilling tool through the reverse screw.
