Technical Field

The invention relates to the field of civil engineering, in particular to a small-diameter rapid pile pulling device for civil engineering and a using method thereof.

Background

Pile-lifting devices are often needed in civil engineering, and the existing pile-lifting methods are roughly divided into two types, namely a full-slewing drilling machine pile-pulling method: the method has unique effect on the cast-in-situ bored pile which is easy to generate uneven pile diameter, namely, the method is very suitable for cast-in-situ bored piles with collapsed hole walls or large bellies in construction. However, for removing other prefabricated square piles, immersed tube cast-in-place piles and prestressed pipe piles, the equipment is over-expensive, the construction efficiency is lower and the pile pulling cost is high. In the pile pulling process, equipment can generate hundreds of tons of counter-force on the ground, if the foundation is not firm, the construction safety and the construction quality are greatly influenced, and therefore, reinforced concrete is required to be completely adopted to harden in the field of the pile pulling area; the other method is a flushing pile pulling method: after the steel pipe larger than the diameter of the old pile is vibrated into the soil layer by a vibration hammer, a large amount of high-pressure water and high-pressure air are used in the pipe to flush the soil around the pile into slurry, the slurry is pumped out and discharged by a pump, and then the pile is pulled out after a pile cap is welded in a hole or a steel wire rope is sleeved on the pile cap by manpower. The method has the advantages of low construction cost and high efficiency. However, due to the pollution of a large amount of mud, the old pile position is rotten and becomes muddy, and the old pile hole cannot be densely backfilled. In the east of China or in cities with soft soil foundations along rivers, the underground water level is 1-2m below the ground, and accidents such as water burst, mud burst, ground collapse, settlement of surrounding buildings, cracking and the like can occur when the shield machine passes through the muddy water vertical well regions. A

Therefore, a pile pulling device which has higher construction speed than other pile pulling methods, lower construction cost and no mud pollution is urgently needed.
