Problems solved by technology

[0002] Cement mixing pile is one of the commonly used equipment in construction at present. It is used to build the foundation for the building. The cement is mixed with the soft soil in the ground soil layer to form a solid pile through the cement mixing method. Cement mixing piles are driven through processes such as drilling, mixing, high-pressure grouting, and lifting; in order to ensure the stability of the building, deep piles need to be driven into the ground, and longer drill pipes are required at this time, so the volume of traditional cement mixing piles It is large, cumbersome to assemble, and difficult to transport. During the operation, a high bracket is required to fix the drill pipe. It needs to be equipped with a very powerful motor to drive the rotation. At the same time, the cement slurry needs to be lifted more than ten meters before being sprayed into the ground pile. It causes a great waste of energy and seriously affects the operation efficiency; in addition, there are safety risks such as drill pipe falling off and workers being injured

Abstract

The invention relates to a chain type cement mixing pile machine which comprises a drill rod, a driver, a bearing frame and a grouting machine. The drill rod comprises a drill bit and a rod body, therod body is formed by splicing transmission columns end to end, the transmission columns are provided with transmission holes in the axis, a bearing pipe is sleeved with the transmission columns in series, and the transmission columns can freely slide on the bearing pipe. One end of the bearing pipe is connected with the drill bit, the other end of the bearing pipe is connected to the grouting machine, the outer column faces of the transmission columns are provided with driving teeth, the driving teeth are engaged with an upper driving wheel on the driver, the driving teeth can be moved relative to the driving wheel in the axial direction of the transmission columns, the bearing frame comprises a lifting arm matched with the bearing pipe, and the bearing pipe can be moved up and down underpulling of the lifting arm. According to the chain type cement mixing pile machine, the structure is novel and unique, conveying and assembling are convenient, operation efficiency is effectively improved, construction occupied space is small, use is safe and efficient and saves energy, and grouting efficiency is improved.
