Problems solved by technology

[0004] However, when the above-mentioned device is in use, the height of the pile hammer in the vertical direction is relatively short, and when the pile hammer falls, the energy generated on the pile cap is small, so that the pile is difficult to move downward.

Abstract

The invention discloses a vertical piling device for prefabricated piles. There is a guide cylinder on the top, and a pile hammer is arranged inside the guide cylinder. Two suspension rings are fixed on the upper end of the pile hammer. A suspension rope is threaded through the two suspension rings. The suspension rope slides and fits with the two suspension rings. Two hoists, the two ends of the suspension rope are fixedly connected with the two hoists, and the lower end of the pile hammer is provided with a pile cap. The structure of the present invention is reasonable, and the clamping device clamps the pile, and fixes the upper end of the pile with the lower end of the pile cap. The impact of the hammer on the pile cap can drive the pile into the ground, and the guide cylinder can make the pile hammer move in the vertical direction, so that the pile can enter the ground vertically.

Description

technical field [0001] The invention relates to the technical field of prefabricated pile driving, in particular to a vertical piling device for prefabricated piles. Background technique [0002] Pile driving device is also called pile driver, it is a kind of piling machine that uses impact force to penetrate piles into the ground, and is widely used in the construction of houses, tunnels and bridges. The quality of piling depends not only on the production quality of the pile itself, but also on the verticality of the pile to the horizontal section of the formation when the pile penetrates into the formation. The better the stress uniformity of the inserted pile, the better the stability of the pile and the higher the safety performance of the pile foundation. At present, in engineering practice, before piling, it is necessary to manually adjust the upper end of the pile directly below the pile hammer of the pile driver, so as to keep the verticality of the pile penetratin...
