Nyob rau hauv kev tsim kho ntawm cov txheej txheem, ib qho kev xam thawj zaug ntawm nws cov kev hnav tsis kam thiab kev coj tus kheej yog qhov tsim nyog. Qee txoj hauv kev yog siv rau cov neeg taug kev, thiab ib txoj hauv kev sib txawv kiag li yog siv los tsim cov txheej txheem tsheb. Lub hauv paus tshwj xeeb pab tiv thaiv qhov kev ntxhov siab uas ua rau cov pavements nyob rau hauv kev khiav tsheb khiav. Rau nws txoj kev tsim, av stabilization yog siv, uas yog siv cov organic thiab inorganic khoom.

Ground Stabilization Overview

Lub hom phiaj tseem ceeb ntawm qhov kev tshwm sim no yog tsim kom muaj lub hauv paus ruaj khov nyob rau hauv txoj kev lossis lub platform, uas yuav tsis deform thiab kis tau thaum lub sijhawm ua haujlwm. Tag nrho cov haujlwm ua haujlwm tuaj yeem muab faib ua plaub theem. Ua ntej ntawm tag nrho cov, cov av stabilization technology muab rau kev npaj ntawm cov khoom los ntawm uas ib hom cushion yuav raug tsim. Tsis tas li ntawd, ib qho kev sib xyaw ua ke yog tsim los ntawm cov khoom nrog cov yam ntxwv xav tau. Twb tau nyob ntawm qhov chaw siv, nrog kev pab los ntawm cov cuab yeej tshwj xeeb, qhov loj yog siv rau thaj chaw ua haujlwm. Cov theem kawg suav nrog kev faib tawm thiab ib hom kev sib xyaw ntawm cov tshuaj nrog cov av hauv paus.

Nws yog ib qho tseem ceeb kom nkag siab tias qhov nocov txheej txheem nws tus kheej tsuas yog ib theem nrab ntawm kev ua raws li tag nrho txoj kev thiab qhov chaw tsim kho qhov project. Thaum av stabilization tiav lawm, insulating los yog technical txheej ntawm lub neej yav tom ntej txheej yog nteg ncaj qha rau ntawm lub hauv paus npaj.

Feem ntau siv cov cement thiab txiv qaub puag. Xuab zeb thiab pob zeb kuj tseem siv tau ua cov thinners - lawv cov concentration nyob ntawm qhov yuav tsum tau ua rau yav tom ntej txheej. Hauv kev tsim kho thiab tsim cov pavement, cov av hauv zos yuav tsum tau siv. Piv txwv li, yog hais tias av stabilization yog nqa tawm nrog txiv qaub, ces nws yuav tsim nyog kom muaj xws li cov ntaub ntawv pob zeb, uas yuav tsim ib tug tsim nyog shock-absorbing zog. Lwm qhov yog tias qhov kev ntxiv no yuav tsum tau ua ntej crushed nrog tshwj xeeb cutters. Ncaj nraim ntawm qhov chaw rov qab, qhov ruaj khov yuav yog kwv yees li 10-20% ntawm cov av hauv zos, uas yuav ua lub hauv paus rau txoj kev nto.

Daim ntawv qhia tshwj xeeb rau kev tsim cov khoom sib xyaw yog txiav txim siab los ntawm cov yam ntxwv uas yuav tsum tau txais tom qab ua tiav ntawm kev ua haujlwm. Piv txwv li, av stabilization txoj kev nrog lub hauv paus monolithic xav tau kev ua tiav ntawm cov txheej txheem zoo li shear resistance thiab nce elasticity. Raws li ib feem ntawm cov kev sib xyaw ua ke, feem ntau siv cov cement-lime ua ke, uas tseem yog diluted nrog cov tshauv nquag thiab cov av hauv zos. Txawm li cas los xij, nws qhov sib txawv tseem ceeb yog kev cais tawm tag nrho ntawm rubble. Yog li ntawd, lwm yam khoom tseem ceeb kuj ua tiav.coatings, ntawm cov uas yog capillary-interrupting zog thiab ib tug nce nyob rau hauv tshav kub-insulating kev kawm.

Technically, kev sib xyaw ua haujlwm yog ua los ntawm cov tshuab txhaj tshuaj tshwj xeeb. Cov cuab yeej siv niaj hnub no tso cai rau koj los sib xyaw ua ke raws li cov ntsuas tau nkag los ntawm kev tswj hwm hluav taws xob. Thawj qhov tsis muaj, raws li txoj kev av stabilized, yog pre-documented nyob rau hauv lub laboratory. Tsis tas li ntawd, cov ntaub ntawv tau los ua lub hauv paus rau kev tsim ib daim ntawv qhia thiab npaj kev sib xyaw kom muaj zog.

Ua ntej theem no, cov thawv tshwj xeeb-cov xa tawm tau npaj, uas cov khoom sib tov tau thauj khoom. Nyob rau tib theem, ntau yam kev hloov kho tuaj yeem muab ntxiv, los ntawm qhov kev ua tau zoo ntawm cov khoom loj tuaj. Ntawm qhov chaw ua hauj lwm, cov cuab yeej sib npaug faib cov dosed binders raws li cov cement thiab txiv qaub. Ntxiv dua thiab, nyob ntawm qhov tsim nyog yuav tsum tau, av stabilization tuaj yeem ua tiav nrog cov ntsiab lus xoob, uas yuav ntxiv cov qib siab dua ntawm kev cog lus ntawm qhov loj. Tsis tas li ntawd, cov txheej txheem pabcuam los npaj cov khoom sib xyaw rau kev faib khoom yuav suav nrog ua ntej xa khoom. Cov no tuaj yeem yog kev ua haujlwm ntawm kev ua haujlwm hauv, sib tsoo thiab sib tov cov khoom ntawm cov khoom loj. Qhov ua tau ntawm kev siv cov txheej txheem thev naus laus zis no nyob ntawm kev ua haujlwm ntawm cov cuab yeej tshwj xeeb. Feem ntau, cov tshuab ua haujlwm ntau yog siv, muab cov cam clutch mechanisms nrog kev tiv thaiv li qub, uas tshem tawm thaumoverloads.

Cov txheej txheem tuaj yeem ua los ntawm cov cuab yeej tshwj xeeb lossis manually. Qhov kev xaiv ntawm kev siv tshuab yog nyob ntawm qhov ua tau ntawm kev ua haujlwm ze ntawm thaj chaw nyob, chaw nres tsheb, chaw dav hlau, lossis huab cua phem. Feem ntau, cov tsheb laij teb nrog peb lub ntsiab lus hitch ntawm lub nraub qaum yog siv rau kev taw qhia zaum kawg ntawm cov khoom. Cutters cuam tshuam ncaj qha nrog cov khoom sib xyaw ua ke - qhov kev txiav txim zoo li loosening ua raws li kev cog lus. Raws li kev tsim qauv daws teeb meem, raws li kev siv cov av stabilization, kev tsim txoj kev ntawm theem no yuav suav nrog kev ua haujlwm ntxiv. Piv txwv li, tus neeg teb xov tooj tuaj yeem faib cov dej-emulsion binder tivthaiv, uas tseem yuav ua haujlwm rau hauv av raws li cov khoom siv sib cais.

Technologies rau kev npaj ntawm txoj kev chaw muaj kev tshwj xeeb rau kev tsim cov txheej tiv thaiv. Lub xub ntiag ntawm cov rwb thaiv tsev zoo thiab cov dej ntws tawm tso cai rau koj los tiv thaiv txoj kev yav tom ntej los ntawm ntau yam tsis zoo. Nyob rau hauv lem, lub stabilization ntawm cov av tsim ib hom ntawm lub hauv paus, uas lub cev siab tom qab ntog. Cov foob no yuav tsum tsis yog tsuas yog tiv thaiv kev ntxhov siab xwb, tab sis kuj ua kom muaj kev ncaj ncees ntawm tag nrho cov qauv ntawm txheej. Nws yog rau qhov no tias viscous Cheebtsam yog ntxiv rau stabilizing mixs. Nyob rau hauv ib qho complex nrog txiv qaub thiab cement, lawv tsim muaj zog, Frost-resistant thiablub platform permeable rau yav tom ntej txoj kev los yog qhov chaw.
