Polymer-sand pobzeb: tshuaj xyuas, kev lag luam kev lag luam

Yog tias peb tham txog qhov yuav tsum tau txhim kho vaj tsev nyob ze ntawm ib lub tsev ntiav, yuav siv tau cov xim polymer-sand, thiab txheeb xyuas txog nws tau nyeem hauv qab no.

Cov nta polymer-xuab zeb vuas

Lub pob zeb-pob zeb, cov txheeb xyuas txog tus tswv yuav tsum tau kawm ua ntej pib ua hauj lwm, raws li crushed polymers, uas muaj lwm cov khoom xyaw rau hauv qhov nyiaj ntawm 25 feem pua. Lawv ua raws li lub caij sib txuas. Feem ntau cov high-pressure polyethylene siv nyob rau hauv no muaj peev xwm, polystyrene los yog polypropylene yuav siv tau. Muaj cov khoom xyaw thiab xuab zeb, uas yog lub ntsiab ntawm cov tub luam, nws ntxiv rau ntawm 75 feem pua. Cov xim ntawm cov khoom yog muab los ntawm dyes, uas yog feem ntau inorganic pigments. Lub pob zeb-xuab zeb, uas feem ntau tsuas yog kev txheeb xyuas, yog ua rau noj nyiaj rau cov xuab zeb, uas yuav tsum muaj qhov nruab nrab ntawm kev ua kom zoo thiab purity. Cov khoom yog ntxuav thiab calcined ntawm high kub. Rau zus ntawm vuas, txoj kev kub pressing ntawm ib tug sib tov raws li polymer-xuab zeb muaj pes tsawg leeg yog siv. Lub tshuab ntawm vibrocompression ntawm ib tug sib tov nyob rau hauv qhuav daim ntawv, thiab raws li kev co, yuav siv tau, thaum lub sij hawm uas plasticizers ntxiv. Lub tom kawg ob txoj kev ua nws tau mus rau kev tsim khoom nrog ib tug tsawg porosity.

Cov khoom zoo ntawm cov khoom polymer-xuab zeb

Lub pob zeb-xuab zeb, uas yog qhov feem ntau pom zoo, muaj ntau yam zoo. Ntawm lawv, peb tuaj yeem paub qhov txawv txav ua haujlwm, zoo li lub zog zoo. Cov khoom muaj ib qib qis ntawm kev puas tsuaj thiab zoo heev noo noo. Cov kua no tsis tuaj yeem txeem tau cov qauv ntawm cov khoom, thiab thaum nws hits nws qhov chaw, nws tshua muaj nyob rau hauv daim ntawv ntawm cov mob. Cov khoom yuav raug cuam tshuam los ntawm roj av thiab roj, tab sis lawv tsis ua phem rau cov khoom.

Kub siab ntawm cov khoom

Cov vuas polymer-xuab zeb, cov khoom siv uas yog ua tiav raws li kev siv tshuab, tiv taus kom tsis muaj peevxwm, yog li cov khoom siv yuav siv txawm tias lub cim ntawm tus pas ntsuas kub yuav poob mus -70 degrees. Cov khoom yog zoo nyob rau hauv tus ntawm aggressive tshuaj media. Vuas polymer-xuab zeb, cov zus uas siv cov khoom siv lub teeb, muaj qhov hnyav negligible, uas yog yooj yim heev rau kev tsim kho. Raws li ib tug shortcoming ntawm cov ntaub ntawv tau piav, tsuas yog lub peev xwm ua kom muaj peev xwm nyob rau hauv tus ntawm kub tau txawv, tab sis qhov no rho tawm tau los ntawm txoj kev ntawm muab ib tug sib txawv nruab nrab ntawm cov khoom nyob sib ze ntawm 4 millimeters.

Nta ntawm nteg vuas

Ua tsaug rau cov ntaub ntawv qhia tau hais los saum toj saud, cov ntau hom paving slabs tuaj yeem tso tau ob qho tib si hauv nroog loj thiab hauv lub tshav puam tsev. Yog li, cov nplaim ntawm cov khoom yuav muaj peev xwm tiv tau qhov feem xyuam ntawm lub tsheb qhov hnyav thiab puas, uas yog siv rau qhov chaw ntawm cov neeg taug kev. Kev txhim kho ntawm cov khoom tuaj yeem nqa tau los ntawm ib qho ntawm cov qauv uas twb muaj lawm: thawj ua rau kev npaj ntawm cov xuab zeb puag, thaum lub sijhawm ob los mus ua kom tiav ntawm ib pob zeb uas muaj tawv ncauj.

Cov lus pom zoo rau kev ua haujlwm

Xuab zeb-polymer paving slabs, xyuas cov uas tsuas lub feem ntau zoo, yuav pw rau ntawm cov xuab zeb qhuav. Nws muaj peev xwm ua tau xuab zeb thiab cement sib tov, uas yog npaj tsis tau ntxiv dej. Nyob rau hauv qhov chaw uas nws yuav tsum tau pw, nws yog ib qhov tsim nyog yuav tsum tau tshem ntawm saum npoo ntawm cov av, lub thickness ntawm uas yuav tsum sib npaug mus rau 20 cm Lub hauv paus yuav tsum tau sib npaug, txawm li cas los, nws yog ib qhov tsim nyog los xyuas kom meej lub slope thiab compact cov av. Ntawm cov npoo nws yog qhov tseem ceeb rau tsim cov curb ditches tsawg, hauv qab uas yuav tsum tau kaw zoo. Nyob rau hauv lub kwj deg ntawm lub pob zeb ntawm ntug kev, cov xuab zeb yuav tsum tau hliv, lub thickness ntawm uas yuav tsum tsis txhob muaj ntau tshaj 5 cm. Cov saum npoo yog dej thiab compacted zoo. Tom qab, kos tus kab ntawm cov ntug kev, thiab tom qab ntawd tsav lub pegs mus rau hauv av, rub ib hlua los yog qaum ntawm lawv.

Ciam thiab pobzeb tso

Khoom siv rau cov vuas polymer-sand tsis yog yuav tsum tau, qhov no simplifies thiab txo tus nqi ntawm cov txheej txheem. Nyob rau hauv lub tom ntej no theem ntawm lub qab ntawm lub grooves yuav tsum tau sau nrog xis mas sib tov, thiab ces teem lub curbstone. Nyob rau hauv compacted txheej ntawm av nws yog ib qhov tsim nyog los nteg linen ntawm geotextile, muab ib tug sib tshooj ntawm 20 centimeters. Nws yog ib qho tseem ceeb kom kho cov npoo nrog ib daim kab xev nplaum. Nyob rau theem tom ntej, cov xuab zeb yog nchuav tawm, cov khaubncaws sab nraud povtseg muaj cov voj voog, txhua tus uas yuav tsum tau muab ntub nrog dej thiab ua noj ua ke rau hauv tus account nqes hav. Tam sim no nws yog ua tau kom nteg vuas, txhua tus neeg cov khoom yog kev txhawb zog ntawm qhov saum toj-hais deb ntawm txhua lwm yam. Nyob rau hauv cov ntaub ntawv no, nws yog ib qhov tsim nyog yuav tau nqa tawm kab rov tav tuab, siv cov roj hmab rauj los kho txoj haujlwm. Ua ntej yuav muab ib lub pob zeb-xuab zeb, koj tuaj yeem ntim cov mesh reinforcing, lub hlwb uas muaj qhov ntev ntawm 50 x 50 millimeters. Tom ntej, ib txheej ntawm qhuav cement-sand sib tov yog tso. Xuab zeb thiab cement yuav tsum tov siv ib feem ntawm 3 mus rau 1. Qhov muaj pes tsawg leeg yuav tsum tau me ntsis moistened. Lub tiav lawm txheej yog nteg pobzeb. Tom qab cov cheeb tsam tsim, nws yog ib qhov tsim nyog yuav tau sau rau hauv cov xuab zeb, uas yuav ua hauj lwm raws li ib tug muab tub lim rau lub dawm.

Dab tsi ntxiv koj yuav tsum paub txog kev tso cov khoom

Cov cuab yeej ntawm kev muab cov xuab zeb-polymer vuas pom zoo tseem muab cov installation ntawm cov khoom ntawm lub hauv paus ntawm crushed pob zeb. Rau qhov no, nyob rau hauv thawj theem, lub siab tshaj txheej txheej ntawm lub ntiaj teb yog muab tshem tawm, hauv qab yog compacted thiab leveled. Ntxiv deepening ua rau lub installation ntawm ntug kev lub pob zeb. Qhov chaw uas tau muab faib rau cov pobzeb yuav tsum tau them rau cov npuas, qhov feem ntawm qhov sib txawv ntawm 20 mus rau 40 millimeters. Daim ntawv no ua kom zoo dua. Tsis tas li ntawd, nyob rau hauv raws li lub txoj kab nqes, ib txheej ntawm qhob screed yog poured, lub thickness ntawm uas yuav ua tau los ntawm 50 mus rau 100 mm. On ib txheej ntawm ib tug daws ntawm xuab zeb thiab xis mas, uas muaj ib tug tuab ntawm 3 centimeters, nws yog ib qhov tsim nyog los nteg lub nplais. Es tsis txhob muab daws, nplais kua nplaum yuav siv tau (raws li qee tus masters, nws yuav zoo dua). Tom qab ntawd tib lub quag yog rubbed ntawm vuas, rau qhov no koj yuav siv tau ib tug txhuam txhuam. Lub cheeb tsam uas tsim tau yuav tsum tau muaj dej nrog.

Kev xyuas neeg mob

Yog tias koj xaiv cov xuab zeb-polymer vuas, qhov tso ntawm cov khoom no, raws li tus paub tswv hais tias, yuav tsum tau nqa tawm ntawm lub lauj kaub nplaum. Qhov no muaj pes tsawg tus yuav tsum tau khov kho kho cov khoom. Cov neeg yuav khoom tom qab lub installation ntawm cov vuas, nco ntsoov tias txoj haujlwm - nws yog ib qho khoom plig, vim koj tsis xav kom ntshai tias cov khoom yuav tawg lossis tawg. Qhov no cia koj tshem tawm txoj kev sib yuav thiab txuag nyiaj. Nyob rau lub caij ntuj no, raws li nyeem tau hauv cov qhua tuaj noj mov, cov pobzeb yuav tu tau los ntawm daus, thiab nws yuav tsis raug puas ntsoog li. Polymer-xuab zeb vuas nrog lawv tus kheej tes kom haum yooj yim, raws li private developers.
