Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide that a kind of perfusion that exceeds setting mixes that the part of doubting native pile crown absolute altitude is rooted out easily, the time spent is few, the reinforcing bar master muscle of pile crown and exposed portions serve is difficult for the processing method of the elevation-exceeding part of impaired concrete pouring pile head.
Realize the technical measures of above-mentioned purpose:
The processing method of elevation-exceeding part of concrete pouring pile head, its step:
1) after the concrete pouring pipe is extracted≤10 minutes in, in the compressed gas arm insertion concrete in the concrete pouring pile head treating apparatus that the control valve that will go up the adjusting main valve installed and pressure meter by compressed gas house steward, the compressed gas arm that is connected with the compressed gas house steward and compressed gas source, compressed gas house steward, connects on the compressed gas arm is formed, and make the bottom of compressed gas arm and pouring pile head require 100~500 mm distance are arranged between the absolute altitude;
2) successively open control valve on the compressed gas arm in the concrete pouring pile head treating apparatus and the adjusting main valve on the compressed gas house steward, make the bottom ejection of compressed gas via the compressed gas arm;
3) after the concrete surface layer of perfusion begins to occur mud bubble in 3~10 minutes, successively close adjusting main valve on the compressed gas house steward in the concrete pouring pile head treating apparatus and the control valve on the compressed gas arm, stop the input of compressed gas;
4) stop the input of compressed gas after, extract with the compressed gas arm that is about in the concrete pouring pile head treating apparatus;
5) part of the setting absolute altitude that exceeds pouring pile head is rooted out.
It is: the compressed gas pressure in the compressed gas arm is 0.3~1.0Mpa.
The present invention compared with prior art, it is owing to adopt Compressed Gas, make the material of the different compositions of each proportion in the concrete material under the effect of gas, produce separating layer, cause cement paste, sand, building stones produce segregation and reduce the intensity of redundance concrete greatly, the bottom that is separating layer is heavy building stones, the upper strata is the little cement paste of proportion, the intermediate layer is the sand material of proportion between building stones and cement paste, mix the part-structure feature that doubtful native pile crown exceeds standard high according to the perfusion after this compressed gas separation, cause the processing of this part is easy to, and the not main reinforcement of easy damaged pouring pile head and pile crown concrete quality, thereby effectively having guaranteed to irritate mixes the pouring quality of doubting native pile crown, for follow-up construction engineering quality has been laid solid foundation.
