Abstract

This invention relates to a walking-type electric dry vibration pneumatic bottom-discharge stone pile machine, comprising a chassis, a column fixedly mounted on one side of the chassis, an electric vibrator slidably mounted on the column, a pile pipe fixedly connected to one end of the electric vibrator via a connecting flange, and a pile head detachably mounted on the end of the pile pipe away from the electric vibrator. After the pile head and pile pipe are driven into the soil to a specified depth, the hinge is forcibly opened by the pressure of compressed air, applying pressure to the stone material, so that the stone material flows evenly into the pile hole, ensuring the amount of stone fed. This completely avoids the "empty pile" quality problem that occurs in traditional construction processes. The pile body produced under the vibration of the pile head has a 100% first-pass quality rate. During hole drilling, compressed air helps the pile pipe and pile head resist the vacuum adhesion resistance of soft soil and maintain the shape of the pile hole.

The dry vibration pile pipe process has the advantages of no water operation, no muddy water pollution, accurate pile diameter control, complete pile shape, good perpendicularity (the upper limit is 1%), good equipment integrity (all functions can be integrated on one pile machine), and the like, and is particularly suitable for the foundation reinforcement treatment with low shear strength such as sandy soil, silt soil, crushed stone soil and soft clay.
