Nekuvandudzwa kwemigwagwa mikuru munyika, matambudziko mazhinji akafumurwa panguva yekushandiswa, sekukuvadzwa kwepamusoro pemugwagwa uye kugadzirisa migwagwa. Aya matambudziko achakanganisa kuchengetedzeka uye kunyaradza kwekutyaira, uye zvakare anokanganisa hupenyu hwebasa remotokari. Taishaninc geogrid shed imhando nyowani ye geosynthetic zvinhu. Zvichienzaniswa nezvimwe zvinhu, ine maitiro ayo akasiyana uye efficacy. Iine simba guru, simba rekutakura mutoro, kusimba kwakasimba, kuvaka nyore uye hupenyu hurefu hwebasa. Nekushandisa polyester geogrid reinforcement kuvandudza kugona kwekubereka kwevhu rakapfava uye kudzikisira kugadzikwa kwaro mushure mekuvaka, tekinoroji yekuvaka yepolyester geogrid yakasimbiswa subgrade yakakurukurwa zvakarongeka, uye inogoneka yekuvaka kutonga kwehunyanzvi matanho akapfupikiswa. Mhedzisiro yekuitwa kwepurojekiti iyi inoratidza kuti polyester geogrid ine zvakanakira simba rakakwirira, simba rekutakura mutoro, kusimba kwakasimba, kuvaka kuri nyore, uye hupenyu hurefu hwebasa, uye inogona kushandiswa mumapurojekiti akafanana.
Taishaninc polyester geogrid reinforced subgrade pavement inoshandiswa zvakanyanya muEuropean mugwagwa wekuvaka. Basa guru re polyester geogrid rinoshandiswa mumigwagwa mikuru rinosanganisira kusimbisa, kuchengetedza, kusefa, kudhiraivha uye kuzviparadzanisa nevamwe. Polyester geogrid inonyanya kukodzera mugwagwa mukuru wakapfava ivhu rekugadzirisa kurapwa, subgrade reinforcement, chikuva kudzoreredza, kupatsanurwa kwemigwagwa mitsva neyekare, kusefa uye dhiraivha, nezvimwe.
(1) Pamberi pekuvakwa kwepamutemo, polyester geogrid zvinhu zvinoda kusarudzwa zvinoenderana nezvinodiwa zvekugadzira. Iyo polyester geogrid inoshandiswa muchirongwa ichi yakatambanudzwa unidirectionally yakakwira-density polyethylene polyester geogrid. Usati waisa, polyester geogrid inofanira kuongororwa. Kana makwinya akawanikwa, anofanira kutwasanudzwa nemagetsi kana nemaoko.
2) Iyo inozadza inoshandiswa mupurojekiti inofanirwa kusangana nezvinodiwa zvinotevera: kupetwa kwemvura kwekuzadza kunofanirwa kuve kwakanaka, uye kona yayo yemukati yekukwesha inofanira kudzorwa mukati me30 °. Kana zvichidikanwa, pane-saiti geotechnical bvunzo dzinofanirwa kuitwa pane yekuzadza; kune micheto yakapinza uye makona mune filler. Ivhu remukati rinofanirwa kudzorwa mukati me15% yehuwandu hwehuwandu hwezvinhu kuti udzivise kukuvadza kune polyester geogrid inokonzerwa nemicheto yakapinza; iyo particle size yezvimedu zvevhu mufiller inofanira kudzorwa mukati me100mm.
Paunenge uchichera uye kuvaka kwebhedha yenheyo, iwe unongoda kutevera iyo yakawanda yekuvaka tekinoroji yemubhedha wenheyo. Hapana imwe tsananguro muchinyorwa chino. Nekudaro, panguva yekuchera bhedha yekuchera bhedha, kutarisisa kwakanyanya kunoda kubhadharwa kuve nechokwadi chekuti bhedha rekuchera rinosangana nedhizaini. uye zvinodiwa pakuvaka. Panguva imwecheteyo, kudzivirira mvura uye matanho emvura anofanira kutorwa mugomba renheyo kuti kuderedze migumisiro yakaipa yemvura. Kana kucherwa kwebhedhi renheyo kwakasimudzwa uye kuumbwa, cushion yematombo inogona kuiswa mushure mekuedzwa kuti ive nechokwadi chekuti inokodzera. Ukobvu hwayo hunofanira kudzorwa pa30cm. Mushure mekunge cushion yematombo yaiswa, inofanira kuenzaniswa nenguva, uye mutsauko unobvumirwa wepamusoro wepamusoro pamusoro pemutsara unofanirwa kudzorwa mukati me10cm. Mushure mekunge mutsara wematombo waiswa, kuiswa kwepolyester geogrid kunogona kutanga. Kutanga, cheka pasi yakasimbiswa grating maererano nezvinodiwa zvekugadzira, uye wozoisa kunze maererano nezvinodiwa zvekugadzira mifananidzo. Humwe hurefu hwegireti hunofanirwa kuchengetwa kunze kwenzvimbo yakatsetseka kuitira kudzosera kumashure. Munguva yekugadzika kwepolyester geogrid, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune chokwadi chekuti kushushikana kwekutungamira kwepolyester geogrid kunofanirwa kuiswa pamwe neiyo longitudinal axis. Polyester geogrids haifanirwe kunge iine majoini padivi peiyo huru yekushushikana kutungamira.
Pakuisa polyester geogrid, nzvimbo, kureba uye nhungamiro yakaiswa mumadhizaini ekugadzira inofanira kuteverwa. Kuwedzera kwehupamhi munzira inofanirwa kudzorwa pa10cm. Mushure mekunge kuiswa kwapera, zvipikiri zvakaumbwa neU zvinoshandiswa kutsigira polyester geogrid. Kupatsanuka kwezvipikiri zveU-kunofanirwa kuchengetedzwa pachinhambwe chakakodzera. Kugadziriswa kweU-yakaita zvipikiri kunogona kudzivirira iyo polyester geogrid kubva pakuchinja panguva yekuzadza kuvaka. Majoini epolyester geogrid pamwe chete neasiri-main stress directions anosungwa netambo dzenaironi, pasina kudiwa kwekupindirana. Kupatsanura pakati pezvisungo kunofanirwa kudzorwa mukati me lm.
Mushure mekunge polyester geogrid yaiswa sezvinodiwa, kuvakwa kwekudzosera kunofanirwa kuitwa nenguva. Nguva yekuratidzwa yepolyester geogrid haifanirwe kunge yakareba kudzivirira matambudziko ekuchembera anokonzerwa nekubuda kwezuva. Munguva yekuvaka kwekudzosera kumashure, saizi yechikamu chekuzadza chinoshandiswa hachifanire kudarika 1/2 yeiyo rolling layer. Munguva yekuzadza kuvaka, iyo migumo miviri yepolyester geogrid inofanira kutanga yazadzwa uye iyo longitudinal chikuva kana nzira yemigwagwa inofanira kuumbwa. , uye ipapo chiyero chekudzosera kumashure chinofanira kukwidziridzwa. Munguva yekudzokororwa kwekuvaka maitiro ekuzadza, traffic yemotokari inorambidzwa pane yakapedzwa polyester geogrid.
Backfill leveling inogona kuitwa nemichina kana nemaoko. Mushure mekuyera kurapwa, mutsauko wepanzvimbo wehurefu pamusoro pepamusoro unofanirwa kudzorwa mukati meScm. Kana kupeta kuvakwa kunoitwa, kunofanira kuitwa zvakarongeka kubva kumativi maviri kusvika pakati. Reverse sequential kuvaka nzira hazvibvumidzwe. Panguva yekuvaka, iyo mugwagwa weiyo mugwagwa unofanirwa kutyaira uchitevedza iyo longitudinal nzira yekumisikidza kudzivirira chiitiko che horizontal kutyaira uye kukunguruka. Mushure mekugadzirwa kwekugadzira kwega rega rekuzadza kwapera, kusungirirwa kwayo kunofanira kuongororwa kuti ione kuti inosangana nezvinodiwa isati yaenderera mberi nekuvaka kwechikamu chinotevera chekuzadza. Iyo compaction degree yekuzadza inodzorwa zvinoenderana neyakajairwa zvinodiwa zveembankments.
