Geocell Nta:

1. Nws tuaj yeem ncab tau yooj yim, tuaj yeem tawg thaum lub sijhawm thauj mus los, thiab tuaj yeem ncab mus rau hauv ib lub net zoo thaum lub sij hawm tsim kho, thiab ntim nrog cov ntaub ntawv xoob xws li av, pob zeb, pob zeb, thiab lwm yam, los tsim cov qauv nrog cov kev txwv tsis pub muaj zog thiab siab rigidity.

2. Cov khoom siv yog lub teeb, hnav-tiv taus, ruaj khov hauv cov khoom siv tshuaj, tiv taus lub teeb thiab oxygen aging, acid thiab alkali resistant, haum rau cov av sib txawv thiab cov suab puam thiab lwm yam av.

3. High lateral txwv thiab tiv thaiv plam, tiv thaiv deformation, zoo txhim khu lub peev xwm ntawm lub subgrade thiab disperse lub load.

4. Hloov geocell qhov siab, vuam nrug thiab lwm yam geometric qhov ntev tuaj yeem ua tau raws li qhov xav tau ntawm engineering sib txawv.

5. Kev nthuav dav dawb thiab kev cog lus me me, kev thauj mus los me me; kev sib txuas yooj yim thiab kev tsim kho ceev ceev.

Engineering daim ntawv thov ntawm chav cell:

1. Ua haujlwm nrog ib nrab-sau thiab ib nrab-subgrade

Thaum tsim ib qho embankment ntawm txoj kab nqes nrog ib qho kev nqes hav tsuas yog 1: 5, cov kauj ruam yuav tsum tau khawb ntawm lub hauv paus ntawm embankment, thiab qhov dav ntawm cov kauj ruam yuav tsum tsis pub tsawg tshaj 1M. Thaum txoj kev yog ua nyob rau hauv theem los yog rebuilt thiab widened, lub hlws ris ntawm lub qub thiab tshiab subgrade sau slopes yuav tsum tau qhib. Rau kev khawb cov kauj ruam, qhov dav ntawm cov kauj ruam ntawm txoj kev loj yog feem ntau 2M. Geocells tau nteg nyob rau theem ntawm txhua kauj ruam, thiab cov geocell tus kheej facade sab-limited reinforcement nyhuv yog siv los daws qhov teeb meem ntawm qhov tsis sib xws.

2. Subgrade nyob rau hauv cua thiab xuab zeb

Txoj kev taug kev hauv thaj tsam cua daj cua dub yuav tsum yog qhov qis qis, thiab qhov siab qhov siab feem ntau tsis tsawg dua 0.3M. Vim yog cov kev cai ntawm txoj kev qis qis thiab hnyav hnyav hauv kev tsim kho hauv txoj hauv kev hauv cov xuab zeb cua, kev siv cov geocells tuaj yeem ua lub luag haujlwm sab nraud hauv xoob txhaws. Qhov siab txwv kom ntseeg tau tias cov subgrade muaj siab rigidity thiab lub zog los tiv thaiv cov kev ntxhov siab ntawm cov tsheb loj.

3. Reinforceing av filling rau subgrade tom qab ntawm lub platform

Kev siv geocells tuaj yeem ua tiav lub hom phiaj ntawm abutment back reinforcement. Cov geocells thiab fillers tuaj yeem tsim kom muaj kev sib txhuam txaus kom txo tau qhov tsis sib haum xeeb ntawm kev sib cais thiab cov qauv, thiab thaum kawg ua kom zoo "abutment jump" Qhov cuam tshuam ntxov ntawm kev puas tsuaj ntawm choj lawj los ntawm "tsheb" kab mob.

4. Subgrade nyob rau hauv permafrost cheeb tsam

Nyob rau hauv kev tsim kho ntawm cov subgrades nyob rau hauv permafrost cheeb tsam, qhov tsawg kawg nkaus filling qhov siab yuav tsum tau mus txog rau tiv thaiv av nkos los yog txo qis ntawm lub sab sauv txwv ntawm cov khov txheej, uas ua rau ntau heev kev sib haum xeeb ntawm embankment. Qhov tshwj xeeb façade reinforcement nyhuv ntawm geocells thiab tag nrho kev kaw ntawm kev siv tau zoo tuaj yeem ua kom qhov tsawg kawg nkaus qhov siab nyob rau hauv qee qhov chaw tshwj xeeb rau qhov loj tshaj plaws, thiab ua kom lub filling muaj lub zog zoo thiab nruj.

5. Kev kho kom tsis txhob muaj kev poob qis

Rau txoj kev loj thiab thawj-chav loj txoj kev hla dhau los ntawm collapsible loess thiab loess seem nrog zoo compressibility, los yog thaum lub tso cai bearing muaj peev xwm ntawm lub hauv paus ntawm lub siab embankment yog qis dua lub load ntawm lub tsheb thiab lub siab ntawm lub embankment tus luj ntawm lub subgrade. kuj yuav tsum tau kho raws li qhov yuav tsum tau muaj peev xwm bearing. Lub sijhawm no, qhov zoo tshaj ntawm geocell yog undoubtedly nthuav tawm.

Geocell siv txoj kev:

1. Lub ntsej muag ua haujlwm: qee qhov kev nqes hav tau ua tau raws li qhov yuav tsum tau ua, thiab kev txhim kho txoj kab nqes tseem tab tom ua, thiab lub ntsej muag ua haujlwm yuav raug muab ua ntu zus. Qhov smoothness ntawm txoj kab nqes yog cuam tshuam nrog kev vam meej lossis tsis ua haujlwm ntawm kev tiv thaiv geocell nyom cog. Thaum txoj kab nqes tsis sib npaug, kev tso ntawm geocells yog qhov ua rau muaj kev ntxhov siab, uas yuav tawg cov pob qij txha ntawm cov hlwb thiab ua rau cov hlwb ua rau thiab lwm yam. Yog li ntawd, txoj kab nqes yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua, thiab txoj kab nqes yuav tsum tau kho manually kom tshem tawm cov pob zeb thiab cov pob zeb txaus ntshai ntawm txoj kab nqes.

2. Sab txoj kab nqes ntawm cov pavement ntawm tes yuav tsum tau nruab nrog lub qhov dej ntws loj, nrog qhov deb ntawm 4m ntawm ob lub kwj deg uas nyob ib sab, thiab cov kwj deg yog txuas nrog sab ditch ntawm txoj kev, kom txoj kev ntog dej ntws. mus rau hauv cov dej ntws raws ntawm sab kwj dej thiab nkag mus rau ntawm ntug ntawm txoj kev, kom tsis txhob muaj cov dej sib xyaw ntawm txoj kev thiab tiv thaiv txoj kab nqes kev tiv thaiv los ntawm scouring cov hlwb.

3. Ua cov txheej txheem saum toj kawg nkaus ntawm txoj kab nqes saum npoo, tshem tawm qee cov khoom siv uas tsis zoo rau kev tso cov hlwb, thiab ua kom txoj kab nqes saum npoo tiaj thiab ruaj khov. Koj tuaj yeem nchuav ib txheej ntawm cov av zoo ua ntej los pab txhawb kev loj hlob ntawm cov nroj tsuag.

4. Lub xovtooj ntawm tes yuav tsum tau muab tso rau ntawm sab saum toj mus rau hauv qab ntawm lub ntsiab lus ntawm kev quab yuam, kom daim ntawv xovtooj ntawm tes yog perpendicular mus rau roadbed. Tsis txhob nteg horizontally.

5. Qhib tag nrho lub xovtooj sib dhos, thiab ntsia hlau rau hauv ib lub xov tooj ntawm tes rau saum. Qhov ntev ntawm cov rivet pawg yuav tsum yog ob zaug qhov siab ntawm lub cell nws tus kheej ntxiv rau 30cm. Piv txwv li, rau 5cm cell, nws cov rivet pawg yuav tsum yog 2 × 5cm + 30cm, 40cm nyob rau hauv ntev, 10cm cell, nws rivet pawg yuav tsum yog 2 × 10 + 30, 50cm nyob rau hauv ntev, thiab cov rivet pawg yog nailed raws cov kua. ditch ntawm ob sab, xyoob thiab ntoo pawg tuaj yeem siv tau, feem ntau yog qhib daim phiaj hauv nruab nrab thiab hauv qab, xyoob thiab ntoo pawg kuj tuaj yeem siv los rub lub cell. Sab saum toj riveting pawg tsuas yog ua lub luag haujlwm ntawm kev dai thiab riveting ntawm tes. Cov ntaub ntawv zoo dua, xws li steel rods, yuav tsum tau siv. Cov ncej steel yuav tsum yog nyob rau sab xis ntawm txoj kab nqes, thiab lwm qhov feem ntau ua lub luag haujlwm ntawm cov hlwb nro thaum tsim kho, thiab cov khoom siv tau yooj yim.

6. Tom qab lub cell yog stretched thiab riveted, sau qhov chaw ntawm tes los ntawm sab saum toj mus rau hauv qab nrog high-zoo av haum rau cog turf los yog nyom noob. Lub filling yuav tsum yog 1.2 npaug ntawm qhov siab ntawm lub cell, thiab nws yuav tsum tau patted khov kho thiab cog rau lub sij hawm ntawm cov nroj tsuag.

7. Thaum siv rau ntawm txoj kab nqes qis ntawm txoj kev, cov kwj deg yuav tsum tau txuas nrog txoj kev lub xub pwg tuav cov kwj deg kom yooj yim rau cov dej ntws ntawm txoj kev dej tsis muaj scouring txoj kev tiv thaiv txoj kab nqes. Thaum siv rau ntawm txoj kab nqes saum toj ntawm txoj kev, ib qho dej thaiv qhov kwj dej yuav tsum tau teeb tsa rau ntawm kab saum toj kawg nkaus ntawm txoj kab nqes. Ua kom cov dej sib xyaw ua ke ntawm qhov siab ntawm txoj kab nqes sab saud mus rau hauv qhov dej ntws los tiv thaiv cov dej hauv av los ntawm kev ntxuav ncaj qha rau txoj kab nqes. Txoj kab nqes saum toj yuav tsum sim siv qhov siab dua geocell.

8. Tom qab kev tsim kho tiav lawm, kev tshuaj xyuas rov qab ua haujlwm yuav tsum ua kom zoo, thiab cov riveting pawg uas tsis tau ncav cuag thiab tsis muaj zog yuav tsum tau rov ua dua nyob rau lub sijhawm kom txog thaum cov turf lossis nyom noob tag nrho.
