Pile pressing equipment

Abstract

The invention discloses pile pressing equipment. The equipment comprises a base, first clamping mechanisms fixed to the two sides of the bottom of the base correspondingly, a first lifting oil cylinder fixed to the rear end of the base, a guide rail closed into a middle hole of the base in a sliding sleeving mode, and a horizontal moving oil cylinder which is arranged on the guide rail and the base and used for moving the base or the guide rail front and back. The equipment further comprises a pile pressing device arranged at the front end of the guide rail, and second clamping mechanisms arearranged on the two sides of the bottom of the pile pressing device. The equipment further comprises a crawler device and a lifting device which enable the base and the pile pressing device to be placed at the top of a planted pile. The front end of the guide rail is in the shape of an arc, the rear end of the pile pressing device is hinged to the front end of the guide rail, and turning oil cylinders used for enabling the pile pressing device to turn horizontally are arranged on the two sides of the front end of the guide rail; fixing blocks used for fixing lifting oil cylinders are hinged tothe rear end of the guide rail; and a rotary drilling machine is mounted on the pile pressing device. The pile pressing equipment can travel to the top end of the planted pile and is positioned or moved, and in addition, the pile pressing device can horizontally turn.

Description

technical field [0001] The invention relates to the technical field of foundation construction, in particular to pile pressing equipment. Background technique [0002] In the field of foundation construction technology, in many occasions, piles need to be closely attached to each other, pressed into the soil and extended along the length direction to form support piles or river cofferdams. The pressure piles or pile planting in the prior art generally initially plant a plurality of piles with a guide device, then set guide frames and other devices on the piles that have been planted, and then use a crane to place the piles to be implanted, such as rectangular piles, into the piles. Or hoist the I-shaped piles into the guide frame, and then use other piling equipment to plant piles in sequence. Obviously, large piling equipment is still needed, especially the guide device still needs other hoisting equipment to be hoisted to the piles that have been planted, and there is no ...

AI Technical Summary

Problems solved by technology

Obviously, large piling equipment is still needed, especially the guide device still needs other hoisting equipment to be hoisted to the piles that have been planted, and there is no piling equipment itself, and because the piles are close to each other, it is easy to rub when the piles are planted As a result, the adjacent piles are forced to sink, so it is difficult to control the piles to be level and equal in height

Another more obvious disadvantage is that the guiding device is difficult to flexibly adapt to the needs of some sites such as the river bank edge horizontally to the continuous zigzag turning pile planting.

In addition, the existing pile planting equipment sometimes encounters hard soil or rocks and other ground conditions, making it impossible to plant piles, and additional large-scale drilling equipment is required, which is costly and time-consuming and seriously affects construction efficiency.
