Anti-blocking reducing bidirectional cement mixing pile

Abstract

The invention discloses an anti-blocking reducing bidirectional cement mixing pile. The anti-blocking reducing bidirectional cement mixing pile comprises a drill rod body, a threaded connecting pipe and a threaded bottom pipe, wherein the center of the outer surface of the threaded connecting pipe is sleeved with a clamping ring, a first sealing ring is fixedly connected to the position, close tothe center, in the threaded connecting pipe, a bearing is embedded in the position, close to the edge of the top end, in the threaded connecting pipe, a connecting frame is embedded in the bearing, and first internal threads are formed in the inner surface wall of the connecting frame. According to the anti-blocking reducing bidirectional cement mixing pile, after the drilling rod reaches the designated depth, cement is effectively poured into equipment through a material guide pipe, at the moment, slurry can be injected into the drilling rod body through a material mixing opening due to rotation of the drilling rod body, and meanwhile excessive cement can be injected into the drilling rod body through a material discharging hole, and under the driving of the rotation of the material guidepipe, a second push sheet can effectively mix and push the mixture of cement and slurry downwards, so that the mixture can be injected into the next section of material guide pipe again through eachconnecting frame.

Description

technical field [0001] The invention belongs to the technical field of cement mixing pile equipment, in particular to an anti-blocking variable-diameter two-way cement mixing pile. Background technique [0002] Cement mixing pile refers to an effective form of soft foundation treatment. It is a main agent that uses cement as a curing agent. The cement is sprayed into the soil by a mixing pile machine and fully stirred to make a series of physical and chemical reactions between the cement and the soil. , to harden the soft soil and improve the strength of the foundation. Cement mixing piles are divided into single-axis, double-axis and three-axis mixing piles according to the main construction methods used. However, in the prior art, cement mixing piles are mostly directly poured into cement through the drill pipe, which makes the drill that has not been cleaned in time The inside of the rod is prone to blockage, which leads to the inability of the drill pipe to effectively ...

AI Technical Summary

Problems solved by technology

Cement mixing piles are divided into single-axis, double-axis and three-axis mixing piles according to the main construction methods used. However, in the prior art, cement mixing piles are mostly directly poured into cement through the drill pipe, which makes the drill that has not been cleaned in time The inside of the rod is prone to blockage, which leads to the inability of the drill pipe to effectively transport the cement, thereby affecting the overall construction process. At the same time, the existing cement mixing pile needs to be moved up the drill pipe at the same time when the cement is poured. The drill pipe needs to be submerged again, and then the cement and mud are stirred and mixed. This operation makes the actual use of the equipment less efficient and makes the actual use of the equipment less effective.
