Artificial nyom yog ib qho zoo heev thiab siv tau lwm txoj hauv kev nyom nyom. Nws tau dhau los ua neeg nyiam nyob hauv tsev, chaw ua haujlwm, thiab cov chaw pej xeem vim nws tsis tshua muaj txij nkawm thiab kav ntev. Txawm li cas los xij, nws yog ib qho tseem ceeb kom paub tias dab tsi mus rau hauv cov nyom dag yog qhov tseem ceeb ib yam li cov nyom nws tus kheej. Qhov zoo thiab muaj pes tsawg leeg ntawm sub-base txheej thiab cov khoom siv infill siv ua lub luag haujlwm tseem ceeb hauv kev ua neej ntev, kev nyab xeeb, thiab kev ua haujlwm ntawm cov nyom dag.
Sub-Base Txheej:
Lub sub-base txheej yog lub hauv paus ntawm txhua qhov kev tsim nyom nyom nyom. Nws yog txheej txheej uas mus rau hauv qab cov nyom dag thiab yog lub luag haujlwm rau kev ruaj ntseg, kev tso dej, thiab kev txhawb nqa. Qhov zoo thiab muaj pes tsawg leeg ntawm sub-base txheej txiav txim siab npaum li cas cov nyom dag yuav ua tau zoo thiab yuav kav ntev npaum li cas.
Thawj kauj ruam yog tshem tawm cov nyom, av, lossis cov khib nyiab uas twb muaj lawm los ntawm thaj chaw uas cov nyom nyom yuav tshwm sim. Cov kauj ruam tom ntej yog ntsuas qhov cheeb tsam thiab kos tawm lub perimeter qhov twg sub-base txheej yuav muab tso rau. Thaum lub perimeter raug cim tawm, ib qho kev sib sau ua ke ntawm cov khoom siv hauv paus yog siv los tsim lub hauv paus ruaj khov rau cov nyom dag. Cov ntaub ntawv pom zoo rau sub-base txheej muaj xws li crushed pob zeb, gravel, thiab txoj kev hauv paus.
Thaum lub hauv paus cov khoom yog theem thiab compacted, ib txheej ntawm ntse xuab zeb los yog pob zeb hmoov av yog ntxiv. Cov txheej no tsim ib qho chaw du rau cov nyom dag kom muab tso rau. Cov xuab zeb los yog pob zeb plua plav txheej yog tom qab ntawd compacted los tsim ib qho chaw txawm. Nws yog ib qho tseem ceeb kom paub tseeb tias lub sub-base txheej yog zoo leveled thiab compacted kom tsis txhob muaj teeb meem thiab unevenness nyob rau hauv cov nyom dag.
Khoom siv:
Infill khoom yog ib txheej ntawm cov khoom me me uas mus rau saum cov nyom dag kom muab cushioning, hnyav, thiab kev txhawb nqa. Cov khoom siv infill ua rau cov nyom dag thiab ua haujlwm zoo li cov nyom nyom. Cov muaj pes tsawg leeg thiab cov khoom siv infilling yuav cuam tshuam rau kev ua haujlwm thiab kev nyab xeeb ntawm cov nyom dag.
Cov ntaub ntawv pom zoo rau cov nyom dag muaj xws li silica xuab zeb, crumb rubber, thiab sib tov ntawm cov xuab zeb thiab cov roj hmab crumb. Silica xuab zeb yog ib qho kev xaiv zoo heev vim nws huv si, muaj txiaj ntsig thiab tuaj yeem pab tiv thaiv cov nyom dag kom kub dhau. Crumb roj hmab yog lwm cov khoom siv nrov nrov, ua los ntawm cov roj hmab rov ua dua tshiab, nws muaj cushioning thiab durability.
Tus nqi ntawm cov khoom siv yuav tsum tau yuav nyob ntawm seb hom nyom dag thiab lub hom phiaj ntawm lub installation. Piv txwv li, kev ncaws pob thiab ncaws pob yuav tsum muaj cov khoom siv ntxiv los muab kev poob siab thiab cushioning. Infill cov ntaub ntawv yuav tsum tau ntxiv tusyees kom ntseeg tau tias cov nyom dag yog theem thiab muaj ib tug zoo sib xws.
Cov txiaj ntsig zoo ntawm Sub-Base Layer thiab Infill Material:
Kev txhim kho kom zoo ntawm cov txheej txheem sub-base thiab cov khoom siv ntxiv yog qhov tseem ceeb rau kev ua haujlwm thiab kev ua haujlwm ntev ntawm cov nyom dag. Cov txiaj ntsig muaj xws li:
1) Lub neej ntev: Ib txheej txheej sub-base thiab cov khoom siv ntxiv yuav txuas ntxiv lub neej ntawm cov nyom dag.
2) Cov dej ntws: Cov txheej txheej sub-base yuav muab cov kua dej kom zoo, tiv thaiv cov dej los ntawm kev sib koom ua ke ntawm qhov chaw.
3) Stability: Lub sub-base txheej ua kom cov nyom dag ruaj khov thiab tiv thaiv nws los ntawm kev hloov lossis txav mus.
4) Cushioning: Cov ntaub ntawv infill muab cov nyhuv cushioning, ua rau cov nyom dag kom zoo thiab siv tau zoo dua.
5) Kev pom zoo: Kev teeb tsa zoo ntawm cov txheej txheem sub-base thiab cov ntaub ntawv sau ua kom muaj qhov zoo ib yam, theem ntawm cov nyom dag.
Nkag siab txog dab tsi mus rau hauv cov nyom dag yog qhov tseem ceeb hauv kev ua kom muaj kev vam meej. Lub sub-base txheej thiab infilling cov ntaub ntawv ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm, kev nyab xeeb, thiab kav ntev ntawm cov nyom dag. Cov txheej txheem kev teeb tsa kom raug thiab cov ntaub ntawv pom zoo yuav tsum ua raws li ib txwm ua kom ntseeg tau tias qhov ua tau zoo tshaj plaws. Thaum txhim kho kom raug, cov nyom dag tuaj yeem yog qhov kev nqis peev zoo rau txhua lub cuab yeej, muab kev saib xyuas qis, ua haujlwm ntev, thiab kev zoo nkauj rau xyoo tom ntej.
