Beckman Beam Pavement Deflection Tester Rebound Deflection Tester 3.6m 5.4m 7.2m

Beckman beam txoj kev yog ib txoj kev uas tsim nyog rau kev ntsuas qhov elastic deflection tus nqi ntawm txoj kev nto nyob rau hauv zoo li qub loading los yog qeeb ceev loading, thiab nws muaj peev xwm zoo cuam tshuam tag nrho lub zog ntawm txoj kev nto.

Khoom siv: aluminium alloy

Ntev: 3.6m, 5.4m, 7.2m

Test Method cov kauj ruam:

1. Peb yuav tsum npaj cov ntsiab lus ntawm qhov kev xeem, qhov kev ncua deb yog nyob ntawm qhov kev xav tau ntawm kev xeem.Lub ntsuas ntsuas yuav tsum yog nyob rau ntawm lub log khiav txoj siv sia ntawm txoj kab tsheb ciav hlau thiab cim nrog cov xim dawb lossis chalk.2. Rau lub tsheb xeem peb yuav siv, lub rear log sib txawv ntawm lub tsheb xeem yog raws li nyob rau hauv txoj hauj lwm txog 3 ~ 5cm tom qab lub ntsuas taw tes, uas yog conducive rau peb soj ntsuam.3. Tom qab ntawd, peb ntxig lub ntsuas deflection rau hauv qhov sib txawv ntawm lub log tsheb ntawm lub tsheb, ua raws li cov kev taw qhia ntawm lub tsheb, lub nqaj caj npab yuav tsum tsis txhob kov lub log, lub deflection gauge sojntsuam yog muab tso rau ntawm qhov ntsuas, thiab lub dial taw qhia yog ntsia rau ntawm deflection Ntawm lub ntsuas pas nrig ntawm lub ntsuas.4. Lub deflection meter peb xav tau tuaj yeem ntsuas ntawm ib sab, lossis nws tuaj yeem ruaj khov rov qab mus rau xoom ntawm ob sab, thiab qhov taw qhia dial yog ntsia rau ntawm lub ntsuas pas nrig ntawm deflection meter.5. Thaum kawg, tus tester tshuab lub xuav kom lub tsheb txav mus tom ntej maj mam, thiab lub dial taw qhia txuas ntxiv tig mus rau pem hauv ntej thaum txoj kev deformation nce.Thaum txhais tes tig mus rau tus nqi siab tshaj plaws, sai sai nyeem qhov pib nyeem L1.
