Abstract

The invention discloses a multistage grouting concrete filling pile which comprises a pile body and is characterized in that a plurality of expanding nodes are arranged on the outer surface of the pile body and fixedly connected with the pile body, and a pile tail is arranged at the lower portion of the pile body and fixedly connected with the pile body. Correspondingly, the invention further provides a construction process of the multistage grouting concrete filling pile. By means of the construction process of the multistage grouting concrete filling pile, the problems that a grouting tube cannot be pulled out, a reinforcement cage is difficult to manufacture, and the traditional grouting pile adapts to the geological conditions poorly can be effectively solved. The nano silica slurry expanding nodes can be arranged at different positions on the multistage grouting concrete filling pile according to actual engineering geological conditions, therefore, activity of common concrete is stimulated, and performance of the pile body is improved. Furthermore, the grouting system has functions of hole cleaning and grouting and can be recycled along with guide tubes after completion of the pile body construction for reutilization. Construction is convenient, and construction cost is reduced.

Description

[0001] technical field [0002] The invention relates to the field of pile foundation engineering of civil engineering, and more specifically, the invention relates to a multi-stage grouting concrete pouring pile and a construction process thereof. Background technique [0003] At present, concrete pouring piles have been widely used in strengthening soft soil foundations. Due to the complexity of engineering geological conditions, it is usually necessary to inject cement slurry at the pile tip and the weak point of the pile body to reduce the influence of pile tip void soil, sediment, mud skin, soil mutation and other factors on the quality of the pile, thereby improving the bearing capacity , to reduce the amount of sedimentation. At present, what is used in the prior art is usually to bind the grouting pipe on the steel cage, which makes it difficult to make the steel cage, and the grouting pipe cannot be pulled out and cannot be reused. At the same time, the pre-fixed ...
