Ndi chitukuko cha misewu ikuluikulu padziko lapansi, mavuto ambiri adawonekera panthawi yomwe amagwiritsidwa ntchito, monga kuwonongeka kwa msewu ndi kukhazikika kwa misewu. Mavutowa adzakhudza chitetezo ndi chitonthozo cha galimoto, komanso adzakhudza moyo utumiki wa galimoto. Taishaninc geogrid shed ndi mtundu watsopano wazinthu za geosynthetic. Poyerekeza ndi zipangizo zina, ili ndi ntchito yake yapadera komanso yothandiza. Ili ndi mphamvu zambiri, mphamvu yonyamula katundu, kukhazikika kwamphamvu, zomangamanga zosavuta komanso moyo wautali wautumiki. Pogwiritsa ntchito polyester geogrid reinforcement kuti apititse patsogolo kukula kwa nthaka yofewa ndikuchepetsa kukhazikika kwake pambuyo pomanga, luso la zomangamanga la polyester geogrid reinforced subgrade linakambidwa mwadongosolo, ndipo njira zoyendetsera zomangamanga zomwe zingatheke zinafotokozedwa mwachidule. Zotsatira za kukhazikitsidwa kwa polojekitiyi zikuwonetsa kuti polyester geogrid ili ndi ubwino wokhala ndi mphamvu zambiri, mphamvu zonyamula katundu, kukhazikika kwamphamvu, kumanga kosavuta, ndi moyo wautali wautumiki, ndipo angagwiritsidwe ntchito m'mapulojekiti ofanana.

Taishaninc polyester geogrid reinforced subgrade pavement imagwiritsidwa ntchito kwambiri pomanga misewu yayikulu ku Europe. Ntchito zazikuluzikulu za polyester geogrid zomwe zimagwiritsidwa ntchito m'misewu yayikulu zimaphatikizapo kulimbikitsa, chitetezo, kusefera, ngalande ndi kudzipatula. Polyester geogrid ndi yoyenera kwambiri panjira yofewa ya nthaka yofewa, kulimbitsa pang'ono, kubwezeretsanso nsanja, kuphatikizika kwamisewu yatsopano ndi yakale, kusefera ndi ngalande, etc.

(1) Asanamangidwe mokhazikika, zida za polyester geogrid ziyenera kusankhidwa malinga ndi kapangidwe kake. Polyester geogrid yomwe imagwiritsidwa ntchito pantchitoyi ndi yotambasulidwa mopanda malire ya polyethylene polyester geogrid. Asanayake, polyester geogrid iyenera kuyang'aniridwa. Ngati makwinya apezeka, akuyenera kuwongoledwa ndi makina kapena pamanja.

2) Zodzaza zomwe zimagwiritsidwa ntchito mu polojekitiyi ziyenera kukwaniritsa zofunikira izi: kutsekemera kwa madzi kwa chodzaza madzi kuyenera kukhala kwabwino, ndipo mbali yake yotsutsana yamkati iyenera kuyendetsedwa mkati mwa 30 °. Ngati ndi kotheka, mayeso a geotechnical pamasamba ayenera kuchitidwa pa filler; pali nsonga zakuthwa ndi ngodya mu filler. Dothi lokhala ndi dothi liyenera kuyendetsedwa mkati mwa 15% ya kuchuluka kwazinthu zonse kuti zisawonongeke ndi polyester geogrid chifukwa chakuthwa m'mphepete; kukula kwa tinthu ting'onoting'ono ta dothi mu filler kuyenera kuyendetsedwa mkati mwa 100mm.

Pamene pofukula ndi kumanga maziko bedi, muyenera kutsatira ambiri zomangamanga luso bedi maziko. Palibe kulongosola kwina m'nkhaniyi. Komabe, panthawi yomanga bedi la maziko, chisamaliro chapadera chiyenera kuperekedwa kuonetsetsa kuti kukumba kwa bedi la maziko kumakwaniritsa kapangidwe kake. ndi zofunikira zomanga. Panthawi imodzimodziyo, njira zotetezera madzi ndi ngalande ziyenera kutengedwa mu dzenje la maziko kuti muchepetse zotsatira zoipa za madzi. Pamene kukumba kwa bedi la maziko kumayendetsedwa ndi kuphatikizika, khushoni ya miyala imatha kuikidwa pambuyo poyesedwa kuti iwonetsetse kuti ndi yoyenerera. Makulidwe ake ayenera kuyendetsedwa pa 30cm. Pambuyo poyika khushoni ya miyala, iyenera kusanjidwa pakapita nthawi, ndipo kusiyana kovomerezeka kwa m'deralo pamwamba pa khushoni kuyenera kuyendetsedwa mkati mwa 10cm. Pambuyo poyika khushoni yamiyala, kuyika kwa polyester geogrid kumatha kuyamba. Choyamba, dulani pansi kulimbitsa grating malinga ndi zofunikira za mapangidwe, ndiyeno muyike molingana ndi zofunikira za zojambula zojambula. Utali wina wa grating uyenera kusungidwa kunja kwa malo otsetsereka kuti upake kumbuyo. Pa kuyika ndondomeko ya polyester geogrid, chidwi chapadera chiyenera kuperekedwa ku mfundo yakuti maganizo a polyester geogrid ayenera kuikidwa pambali patali. Ma polyester geogrids sayenera kukhala ndi zolumikizana motsatira njira yayikulu yakupsinjika.

Poyika polyester geogrid, malo, kutalika ndi njira zomwe zimayikidwa muzojambula zojambula ziyenera kutsatiridwa. Mtunda pakati pawo uyenera kukhala 10 cm. Kuyika kukamalizidwa, misomali yooneka ngati U imagwiritsidwa ntchito pothandizira polyester geogrid. Kutalikirana kwa misomali yooneka ngati U kuyenera kusungidwa patali yoyenera. Kukonzekera kwa misomali yooneka ngati U kungalepheretse polyester geogrid kuti isasunthike panthawi yomanga. Malumikizidwe a polyester geogrid motsatira njira zomwe sizovuta kwambiri amangiriridwa ndi zingwe za nayiloni, popanda kufunikira kodukizana. Kusiyana pakati pa zomangira kuyenera kuyendetsedwa mkati mwa lm.

Pambuyo poyika polyester geogrid ngati ikufunika, kumangidwanso kumayenera kuchitika munthawi yake. Nthawi yowonekera ya polyester geogrid isakhale yayitali kwambiri kuti tipewe mavuto okalamba omwe amayamba chifukwa cha kutenthedwa ndi dzuwa. Pakumanga kubweza, kukula kwa tinthu tazodzaza zomwe zimagwiritsidwa ntchito sikuyenera kupitilira 1/2 ya wosanjikiza. Pakumanga kudzaza, malekezero awiri a polyester geogrid ayenera kudzazidwa kaye ndipo nsanja yotalikirapo kapena njira yamagalimoto iyenera kupangidwa. , ndiyeno kuchuluka kwa kubwezeretsanso kuyenera kukulitsidwa motsatira. Panthawi yomanganso zodzaza, magalimoto amaletsedwa pa polyester geogrid yomalizidwa.

Kubweza kubweza kungatheke pamakina kapena pamanja. Pambuyo pochiza chithandizo, kusiyana kwa kutalika kwapafupi pamtunda kuyenera kuwongoleredwa mkati mwa Scm. Pomangamanga akugubuduza, ayenera kuchitidwa mwadongosolo kuchokera kumalekezero onse mpaka pakati. Njira zomangira motsatizana siziloledwa. Pomanga, wodzigudubuza msewu ayenera kuyendetsa motsatira malangizo kotalika kwa mpanda kupewa chodabwitsa cha yopingasa galimoto ndi anagubuduza. Pambuyo pomanganso gawo lililonse la filler kumalizidwa, kuphatikizika kwake kuyenera kufufuzidwa kuti kuwonetsetse kuti kumakwaniritsa zofunikira musanayambe ntchito yomanga gawo lotsatira la filler. Digiri ya compaction ya kudzaza imayendetsedwa molingana ndi zofunikira zonse za embankments.
