Problems solved by technology

[0003] During the rotation of the mixing blade, cement and soil will be consolidated, and the solidified cement and soil will adhere to the mixing blade, and the mixing blade will lose its mixing function. The quality of the resulting mixing pile is unqualified, the uniformity of the pile body is poor, and the construction efficiency is low.
That is, when the mixing blade is used in the construction of the clay layer, the clay is easy to stick to the mixing blade and rotate with the blade, which affects the pile mixing effect.
[0004] The rigidity of the traditional pile-planting drill pipe is low, and the verticality and cylindricity of the pile are poor. On the one hand, it affects the pile-forming effect, and on the other hand, it wastes cement slurry

Abstract

The invention provides a pile planting construction device. The pile planting construction device comprises a pile frame, wherein a drill rod is arranged on the pile frame, and a power device is arranged at the top of the drill rod. The pile planting construction device is characterized in that a hollow stirring cage is arranged at the lower end of the drill rod; the part, provided with stirring blades, of a stirring shaft at the lower end of the drill rod is located in the stirring cage; fixed blades are arranged in the stirring cage; the fixed blades and the stirring blades on the stirring shaft are arranged in a staggered mode; the drill rod drives the stirring shaft to rotate to cut a stratum; and an outer-layer sleeve and the stirring cage are fixed together and do not rotate. According to the pile planting construction device, the stirring cage is arranged, so that the front end of the drill rod does not shake, and vertical downward drilling in the drilling process is guaranteed.The fixed blades and the stirring blades interact within the range of the stirring cage, cement slurry is fully stirred, and the pile forming effect is good.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a foundation construction equipment. Background technique [0002] Mixing pile construction machinery, in the construction process, usually using a mixing pile machine for construction, the mixing pile machine is provided with a drill pipe, the drill pipe is provided with a stirring blade, the stirring blade rotates and cuts the soil layer, and mixes the cement slurry with the undisturbed soil to form a stream State cement soil. [0003] During the rotation of the mixing blade, cement and soil will be consolidated, and the solidified cement and soil will adhere to the mixing blade, and the mixing blade will lose its mixing function. The quality of the resulting mixing pile is unqualified, the uniformity of the pile body is poor, and the construction efficiency is low. That is, when the mixing blade is used in the construction of the clay layer, the clay is easy to stic...
