Geogrid msewu: ntchito ndi katundu

Chaka chilichonse, anaika kukonza masauzande makilomita misewu. latsopano yomanga nthawi zonse umachitikira ndi katundu panopa ndi ntchito umisiri watsopano, koma kukonzanso kwa nsalu alipo, otchedwa kungokonza mbali zowonongeka, nthawi zambiri njira lotha wosabereka.

The chifukwa komaliza ali otsika khalidwe. Geogrid msewu - makono dongosolo ma kugwiritsidwa ntchito mu yokonza misewu. Technology zokhudza ntchito ya nkhaniyi ndi mkulu khalidwe la ntchito anachita.

Ntchito geogrids Road

Ntchito yomanga latsopano ndi konzanso misewu alipo zolinga zosiyanasiyana - nthambi yaikulu msewu geogrid ntchito. malingana ndi luso atagona angathe kuchitidwa mu zigawo zonse za padziko msewu. Waukulu cholinga geogrid msewu:

• Ndime zolimba pansi kukonza. Geogrid anaika pa phula kuonongeka gawo ndi chivundikiro atsopano aikidwa pamwamba pa izo. Kandalama katundu wa gululi ndi kuteteza kukhudzana pakati padziko latsopano losweka akale. Pamene wosanjikiza izi adzatenge mbali yaikulu ya mavuto yopingasa.
• The madera ndi katundu yaikulu pa njira ya akhoza kupanga dents ndi younikira. Pamene akukonza geogrid yaikidwa mu recess pamwamba pa m'manda phula simenti. Zimenezi zimathandiza kuti kugawira katundu wogawana pa malo lonse, kuteteza mapangidwe dents latsopano.
• Kuika geogrid mu pamwamba msewu ikuchitika ndi pairing zosiyanasiyana zokutira (mwachitsanzo, phula, simenti ndi simenti) pofuna kupewa akulimbana.

• Kulimbikitsa zimfundo pakati pa slabs konkire. Pamene ntchito ndi phula ❖ kuyanika pa maziko a slabs konkire mu malo mating anapanga zofooka zimene kwa ikuthandizira ukonde yaikidwa geogrid msewu.
• Pa kukula kwa msewu pamphambano ya zokutira wogwila latsopano akhoza osokoneza. Pofuna kupewa izi, olowa analimbitsa ndi geogrid.
• zamakono zambiri kupereka kuyambirira nthaka zolimba. Komanso ntchito geogrid msewu. Ntchito wosanjikiza ikuthandizira pomanga tsamba msewu ndi mbali yofunika kwa ndondomekoyi.

Zosiyanasiyana geogrids ndi katundu

View geogrids Mzimuyo tanthauzo lake. Kuwonjezera pa zinthu zakuthupi ndiponso kukula kwa selo, ndi kusiyana ndi njira kupanga zinthu: biaxial (lathu wapawiri) ndi uniaxial (monoorientirovannye). mankhwala Biaxial ndi maselo amakona anayi lakonzedwa kumanga misewu, kuphatikizapo pa nthaka yofewa. Geogrids lathu wapawiri katundu bwino anagawira, amene kumawonjezera moyo. Uniaxial wosanjikiza maselo elongated mkulu kwamakokedwe mphamvu kwambiri kuti mulimbitse dothi, kugumuka ndi maziko obsypnyh.

Zamgululi kwa zolimba wa phula simenti

Geogrid kwa zolimba wa phula simenti msewu limakupatsani kugawira m'dera katundu kunja pa buku lonse mu nsalu pafupi. Nkhanizi ntchito kutalikitsa moyo wa misewu ndi maziko konkire, amene chaka chilichonse umakhala ndi zambiri. Komanso, mauna izi kugawira nkhawa mkati akuwuka kwa shrinkage pang'onopang'ono kuumitsa konkire.

Konkire zolimba Chitsulo mauna sakhalitsa ndipo mtengo. Fiberglass ndi polima geogrids ndi mtengo njira kwa zolimba zachitsulo ndi kukhala nthawi yomweyo zinthu zonse zofunikira:

• Zakuthupi nkhani ndi mankhwala inert, ndi sizinakhudzidwe ndi kusinthasintha kutentha ndi malo konkire zamchere.
• Iwo ali ndi luso lapadera kugawira katundu m'deralo.
• Iwo ali kulemera otsika, moyo wautali, unsembe zosavuta ndi mtengo angagulidwe.

Kusintha ntchitoyo gawo lapansi ntchito pomanga msewu, phula asamalira.

Geogrid kwa kumanga msewu

Chiwundwa tsiku pansi katundu mitsinje zoyendera kumene kumakhala kuchiwonongeko ake ndi mapangidwe maenje, mabowo ndi ming'alu. chifukwa chachikulu - kusowa malo maphunziro. Geogrid owaka miyala zimathandiza phula kuonjezera mphamvu makhalidwe intaneti motsatizana kukana ndi konza amaonera maganizo yopingasa.

Kugwiritsa ntchito zipangizo monga kumanga misewu yatsopano ndi kukonza alipo akhoza kwambiri bwino ntchito ndi kuonjezera moyo wa ❖ kuyanika. Ntchito geogrids kwa kumanga msewu osakaniza geotextile ndi kuchepetsa kumanga misewu chofunika buku zipangizo sanali zachitsulo chochuluka, amene kwambiri kuchepetsa ndalama polojekiti, popanda kusintha kapangidwe khalidwe.

polima geogrids

Geogrid msewu wa ulusi poliyesitala ndi ❖ kuyanika polima pogwiritsa ntchito nitevyazalnoy ndi luso tufting. Zimenezi zimathandiza kusunga koyamba mkulu mphamvu zakuthupi. Kapangidwe ka geogrids - atathana selo kukula, amene ndi woposa wodzazidwa nkhani zawo. Ndi kudzazidwa izi anachitira ndi patsinde pa (nthaka, thanthwe, maziko ina ya zipangizo ntchito pomanga).

zipangizo Polymeric ntchito ngati wosanjikiza ikuthandizira mu zigawo za mmusi za maziko msewu. The ntchito Intaneti polymeric mu zomangamanga msewu zimathandiza kulimbitsa msewu m'munsi ndi kuteteza interpenetration ya zipangizo polumikizana za zigawo zosiyana. Amveke zimatheka ndi kuchepetsa kayendedwe ka granules m'munsi mwa chuma chochuluka kunja kwa chipinda. Anapanga gulu wosanjikiza (granular chuma + geogrid) zatithandiza kukana kuti katundu zazikulu.

Fiberglass Zamgululi

Geogrids zochokera ulusi galasi ntchito ngati ikuthandizira zinthu ndi zigawo zoteteza kulekanitsa yomanga ndi kukonza boma ndi dera misewu, airfields, milatho ndi overpasses. Ntchito magalasi CHIKWANGWANI zolimba grids kwa zokutira phula angadwale nthawi zikugwira ntchito pakati overhauls 2-3. Ndalama kwa yokonza misewu m'madera fiberglass geogrids ntchito mwachangu, yafupika ndi 40%. zomangira mkulu makhalidwe luso m'thupi: kukana kuti media aukali, luso kupirira yopingasa mkulu ndi katundu kotenga. Geogrids fiberglass kwambiri bwino mphamvu ndi katundu mawotchi pomwe zinthu.

kupanga

Pakali pano, opangidwa zotsatirazi mitundu ikuluikulu ya geogrids:

• extruded polima;
• laminated fiberglass;
• Broaching mauna ulusi poliyesitala ndi ulusi galasi.

umisiri wamakono ndi zida ndi masiyanidwe lonse njira yopanga kulola kubala geogrid ndi katundu osiyana zinthu zosiyanasiyana ndi mindandanda yamasewera osiyana mu mfundo. The chofunika mu nkhani iyi ndi:

• kukana kuti zinthu zachilengedwe,
• kukana kuti mapangidwe aukali m'mikhalidwe opaleshoni;
• UV kukana;
• kukana kuti kudziwonengera;
• mphamvu ndi kukhazikika katundu.

Kusankha zinthu

Zosiyanasiyana mitundu ya geogrids ndi makulidwe awo zikhazikitsidwe kusankha kopita, ndondomeko mapangidwe maselo mtundu wa zopangira. interlayers The anapangidwa kuti zolimba, kulekana kwa zigawo, ulamuliro kukokoloka, kuwunikira ndi maziko. Popeza tafotokozera cholinga, muyenera kusankha mtundu wa geogrid ndi kukula kwake. Malinga zipangizo katundu khalidwe amasankhidwa, kumene kungakhale kugonjetsedwa hydro-, bio-, matenthedwe ndi himvozdeystviyu.
