Description

Technical Field

[0002] In construction, pine piles are often used for soft foundation treatment, and the traditional construction pile foundation removal device generally directly breaks the pine piles for removal during use. This direct destruction treatment method not only cannot make the pine piles reused, resulting in waste of building materials, but also produces a lot of noise during the removal process, affecting the normal life of nearby residents, and working under the noise for a long time is likely to affect the hearing health of construction workers, which is not convenient for promotion and use;

[0003] The existing construction pile foundation removal device, for example, has a publication number of CN212641453U, which discloses a construction pile foundation removal device, including a working platform, a mobile mechanism, a lifting platform, a removal mechanism and a lifting mechanism. At least three mobile mechanisms are connected to the bottom of the working platform, and a lifting mechanism is arranged between the lifting platform and the working platform. The removal mechanism is installed at the bottom of the lifting platform. After the removal mechanism is connected to the pile foundation, an external force is applied to the removal mechanism, thereby removing the pile foundation from the ground. There is no violent breaking action in the whole process, and the pile foundation such as pine piles can continue to be used after being pulled out, which increases the utilization efficiency of building materials and is more environmentally friendly and energy-saving. Although the existing construction pile foundation removal device can ensure the integrity of the pile foundation during the process of pile foundation removal, the pile foundation cannot be clamped only by the threaded drill rod, so it is difficult to ensure the stability during subsequent removal, which leads to the fact that the use efficiency and stability of the construction pile foundation removal device cannot be improved.
