The using method of the super filling of underwater cast-in-place pile concrete detector is as follows:
(1), play detector toward putting under water with lining rope, resistance can become greatly when arriving laitance layer, and detector stops to sink, and with lining rope pull-up 50cm up, loosens lining rope then, and this moment, laitance was washed the upper and lower fan sheet that arranges on the leak-proof valve open, and detector continues sinking; When detector no longer sinks, the scale of record good this moment of stake aperture lining rope is mentioned detector then, and the laitance in the coring tube is spread the upper and lower fan sheet on the leak-proof valve out under the effect of gravity, mouth has been guaranteed that by shutoff the detection thing of gathering in the coring tube is not missed at the bottom of the coring tube;
(2), after coring tube is suggested a hole, judge by observation port the interface of laitance and concrete to measure the degree of depth of watering concrete under water, judge by this whether the concrete face is design elevation in hole.
Above-mentioned lower fan sheet is provided with 2 collars.
The outer lower portion of the above-mentioned collar is provided with card article.
Be provided with anti-joint strip between two collars on the above-mentioned lower fan sheet.
The other end end of above-mentioned lining rope is connected with tape measure.
The sharp edge of a knife is arranged in the lower end of above-mentioned coring tube.
Advantage of the present invention is:
The present invention compares with prior art, can carry out underwater cast-in-place pile concrete accurately and build height detection, simultaneously can understand underwater grouting concrete surface condition or pile bottom sediment thickness etc., effectively prevent at the bottom of the Kong Qing unclean, or the inaccurate phenomenon of the face absolute altitude of concrete pouring under water, the use of this detector can make underwater cast-in-place pile reach designing requirement, reduce concrete waste simultaneously, reduce the possibility that potential safety hazard takes place.
