Dab tsi yog fiberglass geogrid?

Tsav tsheb ntawm txoj kev du lossis kev nrawm nrawm ntawm - txoj kev tsheb ciav hlau ceev, tej zaum koj yuav tsis xav txog tias hauv qab ntawm qhov chaw thiab nyob rau hauv txoj kev yog ib qho "tsis pom kev txhawb nqa zoo kawg nkaus"-fiberglass geogrid. Zoo li tsuas yog cov khoom siv mesh nyias, nws ntsiag to dais lub luag haujlwm hnyav ntawm kev cuam tshuam kev ntxhov siab, tiv thaiv kev tawg, thiab ruaj khov ntawm txoj kev hauv tsev, ua rau nws yog ib qho tseem ceeb ntawm cov khoom tseem ceeb hauv cov phiaj xwm niaj hnub no.

 

Niaj hnub no, peb yuav nkag siab qhib cov ntsiab lus kev paub ntawm fiberglass geogrid, los ntawm nws yog dab tsi thiab nws qhov zoo rau nws cov ntawv thov, xaiv, thiab teeb tsa- piav qhia txhua yam hauv ib tsab xov xwm.

 

I. Ua ntej, cia peb nkag siab: Dab tsi yog fiberglass geogrid?

 

Fiberglass geogrid, tseem hu ua iav fiber ntau geogrid, yog ib nrab -cov khoom siv geosynthetic ua los ntawm siab - zog, alkali- dawb iav fiber. Nws yog tsim los ntawm kev siv thev naus laus zis warp knitting los tsim lub mesh substrate, uas yog tom qab ntawd coated nrog kev kho tshwj xeeb nto (xws li hloov asphalt lossis polyester resin). Nws yog ib qho ntawm cov khoom siv dag zog thiab kev tiv thaiv ntau tshaj plaws hauv kev tsim kho vaj tse.

Hauv cov ntsiab lus yooj yim, nws zoo li "tsis pom kev tiv thaiv net" rau cov haujlwm tsim kho vaj tse. Nws combines lub siab zog ntawm fiberglass nrog corrosion kuj thiab compatibility ntawm ib txheej. Cov txheej nyias no muab lub zog txhawb zog, ntsiag to tiv thaiv kev ruaj ntseg thiab kav ntev ntawm ntau yam haujlwm.

Cov txheej txheem tseem ceeb yog qhov yooj yim: fiberglass (lub cev pob txha, muab lub zog tseem ceeb) + txheej txheej (txheej txheej tiv thaiv, txhim kho kev sib raug zoo nrog asphalt thiab pob zeb thiab nws cov kav ntev). Nws cov qauv mesh tso cai rau nws nruj nreem sib cuam tshuam thiab sib koom ua ke nrog cov ntaub ntawv nyob ib puag ncig, tsim kom muaj kev tiv thaiv zoo sib xws uas hais txog lub hauv paus ua rau muaj teeb meem xws li tawg thiab kev sib hais haum hauv engineering tej yaam num.

 

II. Cov txiaj ntsig tseem ceeb: Vim li cas nws tau dhau los ua qhov nyiam hauv kev tsim kho vaj tsev?

 

Fiberglass geogrids tau dav siv nyob rau hauv ntau yam kev tsim kho vaj tse, tsis yog vim lawv qhov kev zoo nkauj, tab sis vim lawv cov txiaj ntsig kev ua tau zoo. Txhua qhov chaw hais meej meej txog qhov mob tseem ceeb hauv cov haujlwm engineering. Cia peb rhuav nws ib qho los ntawm ib qho, thiab koj yuav nkag siab nws cov txiaj ntsig zoo tshaj:

 

1. High Tensile Strength thiab tsis tshua muaj elongation

Lub zog tensile ntawm fiberglass geogrids deb tshaj ntawm cov khoom siv geosynthetic zoo tib yam. Nws cov warp thiab weft tensile lub zog tuaj yeem ncav cuag 60-120 kN / m, lossis siab dua, thaum nws qhov elongation ntawm qhov tawg yog tsawg dua 3%, piv rau qhov toughness thiab lub zog ntawm "infrastructure steel reinforcement." Qhov no txhais tau hais tias nws tuaj yeem cuam tshuam qhov kev ntxhov siab ntawm txoj kev ntawm txoj kev thiab subgrade, tiv thaiv lub zog tensile los ntawm lub tsheb hnyav thiab geological deformation, thiab yuav tsis yooj yim deform. Qhov no txo ​​cov kev sib txawv ntawm qhov chaw xws li rutting thiab tawg los ntawm qhov chaw, ua rau qhov project ruaj khov.

 

2. Huab cua thiab Corrosion Resistant, Ultra-Long Lifespan: Fiberglass nws tus kheej yog cov khoom siv tsis muaj sia, feem ntau yog tsim los ntawm silicon dioxide, muaj lub cev thiab tshuaj lom neeg ruaj khov heev. Ua ke nrog cov txheej txheej tshwj xeeb, nws nthuav tawm cov huab cua zoo tshaj plaws thiab kev tiv thaiv corrosion: kub kub tsis kam (lub ntsiab lus melting ntau tshaj 1000 degree, nws yuav tsis soften los yog deform thaum paving asphalt), tsis kub tsis kam (kev ua tau zoo nyob ruaj khov ntawm -}40 degree, tsis cuam tshuam los ntawm huab cua txias), thiab tiv taus acidic thiab alkaline av, nag erosion. Nws lub neej kev pabcuam tuaj yeem ncav cuag 15-20 xyoo, txo cov nqi kho tom qab tsim kho thiab muab cov nqi zoo.

 

3. Tsis Ntev -Lub Sij Hawm Taug Kev, Muaj Zog Muaj Zog: Raws li cov khoom siv dag zog engineering, "ntev- lub sijhawm tsis yog- deformation" yog qhov yuav tsum tau ua, thiab fiberglass geogrid zoo kawg nkaus ua tau raws li qhov no - nws tsis dhau mus ntev - lub sij hawm nkag (piv txwv li, nws yuav tsis maj mam deform 8} lub sijhawm ua haujlwm ntev sij hawm. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov hauv paus hauv av, hnyav -load pavements, thiab siab - qib highways-scenarios nrog cov kev xav tau ruaj khov siab heev- cuam tshuam tsis zoo rau subgrade kev sib haum xeeb thiab pavement cracking, kom lub sij hawm ntev - stability ntawm qhov project.

4. Kev tsim kho yooj yim thiab tus nqi zoo heev -Kev ua tau zoo

Nws yog lub teeb yuag thiab yoog raws, tso cai rau kev txiav yooj yim thiab splicing. Nws yooj yim yoog mus rau qhov chaw nyuaj xws li nkhaus thiab qhov chaw siab tshaj, tsis tas yuav tsum muaj cov cuab yeej siv loj. Nws tuaj yeem muab tso rau hauv manually lossis mechanically, uas ua rau muaj kev tsim kho siab heev. Tib lub sijhawm, nws txo qis cov khoom siv raw siv hauv qhov project, txo cov nqi tsim kho thiab ntsuas kev yooj yim thiab kev lag luam. Nws tuaj yeem hloov kho tau yooj yim rau ob qho loj - cov phiaj xwm loj thiab cov phiaj xwm me me - nplai tu.

 

III. Daim Ntawv Thov Scenario: Nws Nyob Hauv Cov Cheeb Tsam no

 

Daim ntawv thov ntau ntawm fiberglass geogrid yog dav dua li koj xav. Nws tuaj yeem pom nyob rau hauv yuav luag txhua qhov xwm txheej uas xav tau kev txhawb nqa, kev tiv thaiv tawg, thiab ruaj khov. Nws cov ntawv thov tseem ceeb yog nyob rau hauv 5 qhov chaw loj, tom qab ntawd koj yuav tsis hnov ​​​​tsw tsis paub nrog nws:

 

1. Kev Loj Hlob Engineering (Cov Txheej Txheem Kev Thov Txheej Txheem)

 

Txawm hais tias nws yog txoj kev loj tshiab, txoj kev hauv nroog, lossis kev txhim kho txoj kev qub thiab "dawb-rau-dub" txoj kev ua haujlwm, fiberglass geogrid yog cov khoom siv tseem ceeb. Pw nruab nrab ntawm asphalt nto txheej thiab lub hauv paus txheej, nws zoo tiv thaiv kev cuam tshuam cov kab nrib pleb thiab rutting ntawm txoj kev nto, disperses kev ntxhov siab los ntawm lub tsheb hnyav loads, ncua kev pab cuam lub neej ntawm txoj kev, thiab txo qhov zaus ntawm kev kho tom qab. Qhov no kuj yog qhov xwm txheej uas peb feem ntau ntsib nws hauv peb qhov kev mus ncig txhua hnub.

 

2. Railways thiab Rail Transit: Nyob rau hauv subgrade reinforcement ntawm siab - ceev thiab cov pa railways, fiberglass geogrids zoo suppress subgrade kev sib hais haum thiab tiv thaiv txoj kev deformation, ua rau lawv tshwj xeeb tshaj yog haum rau railway kev tsim kho nyob rau hauv cov av mos mos. Lawv txhim khu tag nrho lub zog ntawm subgrade, disperse vibrations thiab loads los ntawm lub tsheb ciav hlau kev khiav hauj lwm, xyuas kom meej smoothness, thiab ua kom lub tsheb ciav hlau kev nyab xeeb thiab ruaj khov.

 

3. Kev txuag dej thiab kev tiv thaiv kev nqes hav: Hauv cov dej txuag dej xws li cov pas dej, cov ntug dej hiav txwv, thiab cov chaw slopes, fiberglass geogrids tuaj yeem siv los txhawb cov slopes, tiv thaiv av yaig, tiv thaiv dej nag yaig thiab av lwj, txhim khu kev ruaj ntseg ntawm cov dams thiab txoj kab nqes, kom tsis txhob muaj av nkos thiab kev sib tsoo, thiab tiv thaiv kev ruaj ntseg ntawm cov dej.

 

4. Tshav dav hlau thiab Cargo Yards: Tshav dav hlau runways thiab cargo yards yuav tsum tau tiv taus siab -frequency hnyav loads los ntawm aircraft thiab hnyav freight tsheb thauj khoom, yuav tsum tau heev heev hauv av muaj zog thiab stability. Tso fiberglass geogrids zoo txhim kho qhov cuam tshuam hauv av, tiv thaiv kev tawg hauv av thiab kev tawg, ncua kev pab cuam lub neej, thiab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.

 

5. Lwm yam Infrastructure Scenarios

Ntxiv rau cov xwm txheej saum toj no, nws kuj tau siv dav hauv chaw nres tsheb, chaw nres nkoj thiab chaw nres nkoj, qhov hauv ob sab phlu, xuab zeb tswj thiab lwm yam haujlwm. Raws li "tus neeg saib xyuas tsis pom", nws ntsiag to ua lub luag haujlwm hauv kev txhawb nqa, kev tiv thaiv kev tawg thiab kev ruaj khov, dhau los ua "kev txhawb nqa lub luag haujlwm" hauv cov txheej txheem niaj hnub no, tab sis txhawb nqa "kev ruaj ntseg foundation" ntawm qhov project.
