Lub network dej ntws sib xyaw ua ke yog tsim los ntawm ntau yam khoom

Hauv kev tsim kho vaj tse niaj hnub thiab kev tsim kho vaj tse, cov txheej txheem ntws dej yog qhov tseem ceeb heev. Cov dej ntws sib xyaw ua ke muaj kev ua haujlwm ntws dej zoo heev, muaj zog thiab ruaj khov, thiab feem ntau siv rau hauv txoj kev, txoj kev tsheb ciav hlau, qhov av, cov haujlwm txuag dej thiab cov chaw pov tseg. Yog li, nws muaj pes tsawg yam khoom?

Lub vas dej sib xyaw ua ke muaj peb lub ntsiab lus tseem ceeb: lub plawv yas mesh, geotextile uas dej nkag tau thiab ib txheej nplaum txuas ob qho tib si. Peb yam no ua haujlwm ua ke los xyuas kom meej tias cov dej ntws tau zoo, muaj zog thiab ruaj khov ntawm lub vas dej sib xyaw.

1, Yas mesh core

(1) Lub hauv paus yas yog qhov tseem ceeb ntawm cov kav dej sib xyaw ua ke, uas yog ua los ntawm cov polyethylene siab (HDPE) Cov khoom siv yas muaj zog sib npaug yog ua los ntawm cov txheej txheem extrusion tshwj xeeb. Nws muaj cov qauv peb-seem tshwj xeeb, uas yog tsim los ntawm kev sib dhos ntsug thiab kab rov tav. Cov kav no tsis yog tsuas yog muaj kev ruaj khov siab thiab tuaj yeem tsim cov kav dej zoo, tab sis kuj txhawb nqa ib leeg kom tiv thaiv cov geotextile los ntawm kev nkag mus rau hauv cov kav dej, kom ntseeg tau tias qhov ruaj khov thiab kev ua haujlwm ntawm cov kav dej hauv qab qhov hnyav siab.

(2) Muaj ntau yam qauv ntawm cov yas mesh core, suav nrog ob-seem mesh core thiab peb-seem mesh core. Ob-seem mesh core yog tsim los ntawm cov kua dej mesh core nrog ob-rib qauv, thaum peb-seem mesh core muaj peb lossis ntau dua ribs, uas tsim cov qauv nyuaj dua hauv qhov chaw, muab cov peev xwm ntws dej ntau dua thiab lub zog compressive. Tshwj xeeb tshaj yog peb-seem composite kua dej network, nws cov qauv tshwj xeeb tuaj yeem tso tawm cov dej hauv av ntawm txoj kev sai sai thiab thaiv cov dej capillary nyob rau hauv qhov hnyav siab, uas ua lub luag haujlwm hauv kev sib cais thiab kev txhawb nqa lub hauv paus.

2, Dej permeable geotextile

(1) Cov geotextile uas dej nkag tau yog lwm qhov tseem ceeb ntawm cov dej ntws sib xyaw, uas feem ntau sib txuas nrog ob sab lossis ib sab ntawm cov yas mesh core los ntawm cov txheej txheem thermal bonding. Cov geotextile uas dej nkag tau yog ua los ntawm cov koob punched non-woven geotextile, uas muaj dej permeability zoo heev thiab tiv thaiv kev lim dej. Nws muaj peev xwm tiv thaiv cov av thiab cov khoom me me kom tsis txhob nkag mus rau hauv cov kav dej ntws, nws kuj tso cai rau cov dej noo kom dhau mus dawb, ua kom ntseeg tau tias muaj cov dej ntws tsis muaj kev cuam tshuam.

(2) Kev xaiv cov geotextile uas dej nkag tau muaj feem cuam tshuam tseem ceeb rau kev ua haujlwm ntawm cov dej ntws sib xyaw. Cov geotextile zoo uas dej nkag tau tsis tsuas yog muaj qhov loj me zoo, dej nkag tau thiab permeability, tab sis kuj muaj lub zog puncture siab, lub zog tsim kua muag trapezoidal thiab lub zog tensile tuav, yog li ntawd nws tuaj yeem tiv taus ntau yam zog sab nraud thiab kev puas tsuaj ntawm ib puag ncig hauv kev siv mus sij hawm ntev.

3, Txheej nplaum

(1) Cov txheej nplaum yog qhov tseem ceeb los txuas cov yas mesh core thiab cov dej-permeable geotextile. Nws yog ua los ntawm cov khoom siv thermoplastic tshwj xeeb. Los ntawm cov txheej txheem kub bonding, cov txheej nplaum tuaj yeem sib xyaw ua ke cov yas mesh core thiab cov dej-permeable geotextile los ua ib lub network dej sib xyaw nrog cov qauv sib xyaw. Cov qauv no tsis yog tsuas yog ua kom muaj kev ruaj khov thiab ruaj khov ntawm lub network dej, tab sis kuj ua rau nws txoj kev teeb tsa thiab kev tso yooj yim dua thiab sai dua.

(2) Kev ua tau zoo ntawm cov txheej nplaum muaj feem cuam tshuam tseem ceeb rau kev ua haujlwm ntawm cov dej ntws thiab kev tiv thaiv kev laus ntawm cov ntaub thaiv dej sib xyaw. Cov txheej nplaum zoo tuaj yeem ua kom lub ntaub thaiv dej ntws yuav tsis tawg lossis poob thaum siv ntev, thiab tuaj yeem ua kom muaj kev sib txuas thiab ruaj khov ntawm cov txheej txheem dej ntws.

Raws li pom tau los ntawm saum toj no, lub vas dej sib xyaw ua ke muaj peb yam khoom: lub plawv yas mesh, geotextile uas dej nkag tau thiab txheej nplaum. Cov khoom no ua haujlwm ua ke kom ntseeg tau tias cov dej ntws tau zoo, muaj zog thiab ruaj khov ntawm lub vas dej sib xyaw.
