Cov kav dej sib xyaw ua ke peb sab yog cov khoom siv feem ntau siv hauv cov haujlwm loj. Yog li, yuav tsum ua li cas thiaj txhawb tau nws?
1. Cov qauv yooj yim thiab cov yam ntxwv ntawm peb-seem composite dej ntws network
Cov dej ntws sib xyaw ua ke peb-seem yog ua los ntawm peb-seem geonet ob-sab sib txuas geotextile, yog li nws tsis tsuas yog muaj cov nyhuv tiv thaiv kev lim dej ntawm geotextile, tab sis kuj muaj cov dej ntws thiab kev tiv thaiv zoo li geonet. Nws cov qauv peb-seem tshwj xeeb tuaj yeem tiv taus cov khoom siv compressive siab thoob plaws kev siv thiab tswj tau qhov tuab ntau, uas tuaj yeem muab cov hydraulic conductivity zoo. Nws kuj muaj cov yam ntxwv zoo heev xws li lub zog tensile siab, lub zog shear siab, tiv taus corrosion thiab tiv taus kev laus.
2. Txoj kev txhawb zog ntawm peb-seem kev sib xyaw ua ke dej ntws network
1, Kev kho mob hauv paus
Ua ntej yuav tso cov kav dej peb sab sib xyaw ua ke, lub hauv paus yuav tsum tau kho kom zoo. Lub hauv paus yuav tsum tiaj tus thiab nias kom tsis muaj pob zeb ntse, cov cag ntoo thiab lwm yam khib nyiab, kom tsis txhob tho lub vas dej. Lub hauv paus tsis muaj zog yuav tsum tau txhawb kom zoo dua qub kom lub hauv paus muaj peev xwm thiab ruaj khov.
2 、 Sib tshooj thiab kho kom ruaj khov
Thaum tso cov kav dej sib xyaw ua ke peb-seem, qhov ntev sib tshooj yuav tsum tau txiav txim siab raws li qhov xav tau tsim thiab cov xwm txheej kev tsim kho tiag tiag, feem ntau tsis tsawg dua 15 cm. Txoj kev kho tuaj yeem siv U Hom rau tes, pob qij txha lossis cov hlua nylon, thiab lwm yam, xyuas kom meej tias qhov kev sib txuas ntawm lub vas dej ntws thiab lub hauv paus lossis lub vas dej ntws sib ze yog khov kho kom tiv thaiv kev swb thiab kev hloov chaw.
3 、 Backfill thiab compaction
Tom qab kev tso cov kav dej sib xyaw ua ke peb-seem tiav lawm, kev kho rov qab yuav tsum tau ua tiav raws sijhawm. Cov khoom siv rov qab yuav tsum xaiv cov xuab zeb lossis cov av xuab zeb uas muaj dej nkag tau zoo, thiab rov qab ntim thiab sib zog ua cov txheej. Qhov degree compaction yuav tsum ua tau raws li qhov yuav tsum tau tsim kom ntseeg tau tias muaj kev sib cuag zoo thiab cov kav dej ntws ntawm cov kav dej ntws thiab cov khoom siv rov qab.
4, Kev kho mob kom ruaj khov
Yuav kom txhim kho qhov cuam tshuam ntawm cov dej ntws sib xyaw ua ke peb-seem, cov khoom siv txhawb nqa, xws li geogrid thiab geotextile, kuj tuaj yeem muab tso rau ntawm nws. Cov khoom siv txhawb nqa tuaj yeem txhim kho lub zog tensile thiab lub zog shear ntawm cov dej ntws thiab txhim kho nws qhov ruaj khov tag nrho. Txoj kev tso thiab tus lej ntawm cov txheej ntawm cov khoom siv txhawb nqa yuav tsum tau txiav txim siab raws li cov kev xav tau tshwj xeeb ntawm engineering.
5, Kev ua ntug
Kev kho ntug ntawm lub vas dej peb-seem sib xyaw ua ke kuj tseem ceeb heev. Cov ntug yuav tsum tau kho nrog cov txheej txheem tshwj xeeb, xws li teeb tsa cov kwj dej ntws, txhim kho cov cuab yeej kho ntug, thiab lwm yam, uas tuaj yeem tiv thaiv dej kom tsis txhob ntws tawm ntawm ntug lossis ntug ntawm lub vas dej ntws kom tsis txhob puas.
3. Kev ntsuam xyuas thiab kev saib xyuas ntawm cov txiaj ntsig ntawm kev txhawb nqa
Tom qab ua tiav qhov kev txhawb nqa, nws cov txiaj ntsig txhawb nqa yuav tsum tau soj ntsuam thiab saib xyuas. Txoj kev ntsuam xyuas tuaj yeem siv kev sim hauv thaj teb, kev sim hauv chaw kuaj mob lossis kev sim lej, uas tuaj yeem txheeb xyuas seb qhov txiaj ntsig txhawb nqa puas ua tau raws li qhov yuav tsum tau tsim. Lub network dej ntws kuj tseem yuav tsum tau kuaj xyuas thiab tswj xyuas tsis tu ncua kom ntseeg tau tias nws ua haujlwm ruaj khov mus sij hawm ntev.
Los ntawm saum toj no, peb pom tau tias kev kho kom ruaj khov ntawm cov kav dej sib xyaw ua ke peb-seem yog qhov tseem ceeb kom ntseeg tau tias nws ua haujlwm tau zoo. Los ntawm kev kho lub hauv paus, kev sib tshooj thiab kev kho, kev rov qab sau thiab kev sib zog, kev kho kom ruaj khov thiab kev kho ntug, lub peev xwm dais thiab kev ruaj khov ntawm cov kav dej tuaj yeem txhim kho thiab nws lub neej ua haujlwm tuaj yeem ntev dua. Hauv kev tsim kho tiag tiag, nws yog qhov tsim nyog los xaiv cov txheej txheem thiab cov ntaub ntawv txhawb nqa raws li cov kev xav tau tshwj xeeb ntawm kev tsim kho thiab cov xwm txheej geological kom ntseeg tau tias qhov zoo thiab kev nyab xeeb ntawm kev tsim kho.
