Yuav ua li cas ua Pile Integrity Test?


Tus PIT ua qhov kev sib npaug ntawm lub hauv paus uas tsis yog lub hauv paus tshawb fawb uas paub hu ua Low Cawv Impact Ntsuas Cov Kev Ntseeg los sis Qis Tshaj Tawm Dynamic Tests. Cov kev kuaj no tej zaum yuav ua tau los ntawm Pulse (los yog Sonic) Echo los yog Transient Response Methods.


Qhov kev ntsuam xyuas PIT muaj txuas ib lossis ob lub iav accelerometer mus rau lub hauv paus thiab siv lub tawb plaub hau los cuam tshuam rau nws. Tus PIT khaws cov ntaub ntawv siv ceev thiab qhia cov curves uas qhia txhua yam kev hloov tseem ceeb hauv tshooj ntawm seem uas muaj nyob hauv cov ncej.


Cov pawg saum taub hau yuav tsum mus yoojyim, dej saum toj, thiab huv ntawm cov xoob qhob av, av los yog lwm yam ntaub ntawv txawv teb chaws los ntawm kev tsim kho. Txhua hom kev kis kab mob yuav tsum tau muab tshem tawm (siv ib lub pob zeb) kom ncav cuag lub pob zeb thiab cov pob zeb. Cov kauj ruam no tseem ceeb heev, vim hais tias qhov kev sib txuas ntawm lub sensor thiab cov pob zeb yuav tsum yog khoom (sib cuag hu). Qhov chaw nyob ntawm tus sensor yuav tsum raug xaiv kom deb ntawm cov ntug ntawm pawg. Kev kuaj kom muaj kev ncaj ncees yuav tsum tau ua tsis tau sai dua 7 hnub tom qab uas muab zais los yog tom qab muab pob zeb ua kom tiav tsawg kawg 3/4 ntawm nws cov qauv tsim, seb qhov twg tshwm sim ua ntej.

Ib tug rauj (nrog los yog tsis muaj kev txhuaj ntsuas ntsuas) yog siv rau kev cuam tshuam cov pawg sab saum toj; qhov feem cuam yuav tsum tau thov ua haujlwm nrog pawg. Motion transducer yuav tsum muaj peev xwm nrhiav tau thiab teev cov thaub qab reflected hla saum pawg. Kev siv ceev, kev tshaj tawm, lossis kev hloov chaw mus los yuav siv tau rau lub hom phiaj no. Qhov tsawg, acceleration transducer yuav tsum muaj Analog rau Digital Converter nrog 12 ntsis kev daws teeb meem; thiab Tus Qauv Ua Zauv ntawm tsawg kawg 25 KHz.


Cov Pile Integrity Tester muaj nyob rau hauv ntau qhov kev teeb tsa kom haum cov kev xav tau ntawm txhua tus neeg siv. Nrhiav seb tus qauv twg yog rau koj nyob ntawm no: https://www.cqtopgeo.com/pile-tester/pile-integrity-tester/low-strain-pile-integrity-tester.html
