1. Keeb kwm Technology
Tam sim no, WIM systems raws li piezoelectric quartz hnyav sensors yog dav siv nyob rau hauv tej yaam num xws li overload xyuas rau choj thiab culverts, non-site overload tub ceev xwm rau txoj kev loj freight tsheb, thiab technological overload tswj. Txawm li cas los xij, kom ntseeg tau tias qhov tseeb thiab kev pabcuam lub neej, cov haujlwm zoo li no yuav tsum tau siv cov cement pob zeb ua kom rov tsim kho dua tshiab rau piezoelectric quartz hnyav qhov ntsuas qhov ntsuas qhov chaw nrog cov thev naus laus zis tam sim no. Tab sis nyob rau hauv qee qhov kev thov ib puag ncig, xws li choj decks lossis hauv nroog txoj hauv kev nrog cov tsheb thauj neeg hnyav (qhov twg cov cement curing lub sij hawm ntev dhau lawm, ua rau lub sij hawm ntev kaw txoj kev nyuaj), cov haujlwm no nyuaj rau kev siv.
Yog vim li cas piezoelectric quartz hnyav sensors tsis tuaj yeem ntsia ncaj qha rau ntawm txoj kev yooj yim yog: Raws li pom hauv daim duab 1, thaum lub log (tshwj xeeb tshaj yog nyob rau hauv qhov hnyav) mus rau ntawm txoj kev yooj yim, txoj kev nto yuav muaj qhov loj me me. Txawm li cas los xij, thaum mus txog qhov nruj piezoelectric quartz qhov hnyav sensor cheeb tsam, cov yam ntxwv ntawm lub sensor thiab cov pavement interface yog txawv. Tsis tas li ntawd, qhov hnyav hnyav sensor tsis muaj kab rov tav adhesion, ua rau lub ntsuas qhov hnyav sai sai thiab cais tawm ntawm txoj kev.
(1-log, 2-hloov sensor, 3-mos puag txheej, 4-txheej txheej txheej, 5-txoj kev yooj yim, 6-subsidence cheeb tsam, 7-ua npuas ncauj ncoo)
Vim muaj cov yam ntxwv sib txawv thiab qhov sib txawv ntawm txoj kev sib txhuam coefficients, cov tsheb dhau los ntawm piezoelectric quartz hnyav sensor muaj kev vibrations hnyav, cuam tshuam rau qhov hnyav tag nrho. Tom qab lub tsheb compression ntev ntev, qhov chaw yuav ua rau muaj kev puas tsuaj thiab tawg, ua rau muaj kev puas tsuaj rau lub cev.
2. Kev daws tam sim no hauv daim teb no: Cement Concrete Pavement Reconstruction
Vim qhov teeb meem ntawm piezoelectric quartz hnyav sensors tsis tuaj yeem ntsia ncaj qha rau ntawm asphalt pavement, qhov kev ntsuas dav siv hauv kev lag luam yog cement qhob pavement reconstruction rau piezoelectric quartz hnyav sensor installation cheeb tsam. Qhov kev tsim kho dav dav dav dav yog 6-24 meters, nrog qhov dav sib npaug ntawm txoj kev dav.
Txawm hais tias cov cement pob zeb reconstruction ua tau raws li lub zog yuav tsum tau rau kev txhim kho piezoelectric quartz hnyav sensors thiab xyuas kom meej lub neej kev pab cuam, ntau yam teeb meem loj txwv nws cov kev txhawb nqa, tshwj xeeb tshaj yog:
1) Extensive cement hardening reconstruction ntawm thawj pavement yuav tsum tau ib tug ntau ntawm cov nqi ntawm kev tsim kho.
2) Cement pob zeb reconstruction yuav tsum tau siv sij hawm ntev heev. Lub sijhawm kho rau cov cement pavement ib leeg xav tau 28 hnub (tus qauv yuav tsum tau ua), ua rau muaj kev cuam tshuam loj rau lub koom haum tsheb. Tshwj xeeb tshaj yog nyob rau qee kis uas tsim nyog WIM systems tab sis cov tsheb khiav ntawm qhov chaw siab heev, kev tsim kho feem ntau nyuaj.
3) Kev puas tsuaj ntawm cov qauv ntawm txoj kev qub, cuam tshuam cov tsos.
4) Kev hloov pauv sai ntawm kev sib txhuam coefficient tuaj yeem ua rau skidding phenomena, tshwj xeeb tshaj yog nyob rau hauv rainy tej yam kev mob, uas yuav yooj yim ua rau raug xwm txheej.
5) Cov kev hloov hauv txoj kev tsim ua rau lub tsheb vibrations, uas cuam tshuam rau qhov hnyav ntawm qhov raug.
6) Kev tsim kho cov cement pob zeb tsis tuaj yeem ua tiav ntawm qee txoj kev tshwj xeeb, xws li cov choj nce siab.
7) Tam sim no, nyob rau hauv lub tshav pob ntawm txoj kev tsheb, txoj kev yog los ntawm dawb mus rau dub (hloov cov cement pavement rau asphalt pavement). Cov kev daws teeb meem tam sim no yog los ntawm cov xim dub mus rau xim dawb, uas tsis sib haum nrog cov kev xav tau, thiab cov chav tsim kho feem ntau tiv taus.
3. Txhim kho cov txheej txheem kev teeb tsa
Lub hom phiaj ntawm cov tswv yim no yog los daws qhov tsis txaus ntawm piezoelectric quartz hnyav sensors tsis tuaj yeem raug ntsia ncaj qha rau ntawm asphalt qhob pavement.
Cov tswv yim no ncaj qha tso cov piezoelectric quartz hnyav sensor rau ntawm cov txheej txheem nruj, zam qhov teeb meem tsis sib haum mus ntev los ntawm qhov ncaj qha embedding ntawm cov qauv nruj sensor rau hauv txoj kev yooj yim. Qhov no ua rau lub neej ua haujlwm ntev heev thiab ua kom qhov tseeb ntawm qhov hnyav tsis cuam tshuam.
Tsis tas li ntawd, tsis tas yuav ua cov cement pob zeb ua kev txhim kho ntawm qhov qub asphalt pavement, txuag nyiaj ntau ntawm kev tsim kho thiab txo lub sijhawm tsim kho, muab kev ua tau zoo rau kev nce qib loj.
Daim duab 2 yog daim duab schematic ntawm cov qauv nrog lub piezoelectric quartz hnyav sensor muab tso rau ntawm lub hauv paus mos.
(1-log, 2-hloov sensor, 3-mos puag txheej, 4-txheej txheej txheej, 5-txoj kev yooj yim, 6-subsidence cheeb tsam, 7-ua npuas ncauj ncoo)
4. Cov thev naus laus zis tseem ceeb:
1) Pretreatment excavation ntawm lub hauv paus qauv los tsim ib tug reconstruction qhov, nrog ib tug qhov tob ntawm 24-58 cm.
2) Leveling hauv qab ntawm lub qhov thiab nchuav cov khoom muab tub lim. Ib qho piv txwv ntawm quartz xuab zeb + stainless hlau xuab zeb epoxy resin yog nchuav rau hauv qab ntawm qhov, sib npaug sib npaug, nrog rau qhov tob ntawm 2-6 cm thiab leveled.
3) Pouring lub hauv paus txheej txheej thiab txhim kho qhov hnyav sensor. Muab cov txheej txheem nruj thiab embed lub ntsuas qhov hnyav rau hauv nws, siv lub tshuab ua npuas ncauj (0.8-1.2 hli) txhawm rau cais ob sab ntawm lub ntsuas qhov hnyav los ntawm cov txheej txheem nruj. Tom qab lub hauv paus txheej txheej solidifies, siv lub grinder los zom cov ntsuas qhov hnyav thiab cov txheej txheem nruj rau tib lub dav hlau. Lub hauv paus txheej txheej tuaj yeem yog ib qho nyuaj, semi-rigid, lossis txheej txheej txheej.
4) Casting ntawm txheej txheej. Siv cov khoom sib xws nrog cov txheej txheem yooj yim los ncuav thiab sau cov qhov siab ntxiv ntawm lub qhov. Thaum lub sij hawm pouring txheej txheem, siv ib tug me me compaction tshuab kom maj mam compact, kom lub zuag qhia tag nrho theem ntawm reconstructed nto nrog rau lwm txoj kev nto. Lub hauv paus txheej txheej yog nruab nrab-nplua granular asphalt nto txheej.
5) Qhov sib piv thickness ntawm cov txheej txheem nruj rau cov txheej txheem yooj yim yog 20-40: 4-18.
