Small-diameter rapid pile pulling device for civil engineering and using method thereof
The invention provides a small-diameter rapid pile pulling device for civil engineering and a using method thereof, and relates to the field of engineering instruments. The small-diameter rapid pile pulling device for civil engineering comprises a disc-shaped base, a cylinder body is fixedly connected to the upper end of the base, a piston and a push rod are sequentially arranged in a cavity in the cylinder body from bottom to top, the lower end of the push rod is hollowed out to be provided with a combustion chamber, and a clamping mechanism is fixedly connected to the upper end of the push rod; and a hydraulic oil cavity is arranged below the piston. The combustion chamber is arranged, impact force generated by detonation of the combustion chamber is used for pile pulling, and due to the impact force generated instantly, in the pile pulling process, the soil carrying amount of a pile body can be reduced, damage to a soil layer is reduced, and the pile pulling speed is greatly increased.
本发明提供一种土木工程用小直径快速拔桩装置及其使用方法，涉及工程器械领域。该一种土木工程用小直径快速拔桩装置，包括盘形底座，所述底座的上端固定连接有缸体，所述缸体内部的腔室中由下往上依次设置有活塞和推杆，所述推杆的下端掏空设置有燃烧室，所述推杆的上端固定连接有夹持机构，所述活塞的下方为液压油腔。通过设置燃烧室，在其爆燃产生的冲击力用于拔桩，由于瞬间产生的冲击力在拔桩过程中，可以减少桩体携土量，降低对土层的破坏，并且大大提高拔桩的速度。
