1, Asphalt impregnation kurapwa pamusoro pekumanikidza inonamira inonamatira ye geogrid
Iyo geogrid yepamusoro yakamisikidzwa ne-self-adhesive pressure-sensitive adhesive kudzora geogrid.Asphalt yakamisikidzwa yekuzvinamira kumanikidza-inonzwa inonamira pamusoro pe geogrid ndiyo huru geosynthetic zvinhu zve geogrid.Kuenzaniswa nedzimwe geosynthetics, HDPE geomembrane inoratidza zvizere huchokwadi hwayo uye kushanda kwayo.Geogrid inowanzo shandiswa sekusimbisa zvinhu zveyakasimbiswa pasi chimiro kana yekusimbisa zvinhu zvealuminium alloy geotextile mugadziri.
Geogrid yakakamurwa kuita zvikamu zvina: plastiki geogrid, simbi-plastiki geogrid, girazi faibha geogrid uye girazi faibha polyester geogrid.Plastiki geogrid izere rectangular kana rectangular polymer network zvinhu zvinogadzirwa nekuveura kunofambira mberi.Zvinoenderana nekuenderana kweiyo extrusion kutungamira panguva yekukopa maitiro, inogona kukamurwa kuva mhando mbiri: imwe-nzira yekuveura uye maviri-nzira extrusion.
Iko kubaya maburi pane mamwe maplateti epolymer akabatwa neextrusion, uye wobva wasundira kumberi kutatarika kwakananga pasi penzvimbo yekutonhodza.Kana kutsemuka kwe geotextile kuri kusvika 10% yehukuru hwepumburu, isu tinofanirwa kushandisa chikamu chakakanganisika, tobva tabatanidza mafungu maviri epasi zvakanyanya.Mukuwedzera, kana gomba riri pamusoro pemateru kusvika ku10% yehukuru hwepumburu, iyo geotextile roll inofanira kubviswa uye kutsiviwa nemupumburu mutsva.Iyo yekuputira iyo inoshandiswa neiyo geogrid geomembrane mugadziri mune mushure mekurapa maitiro anonangwa kune asphalt composite inogadzira zvinhu.
Imwe neimwe fiber yakavharwa zvachose uye inopindirana zvizere neasphalt, kuitira kuti ive nechokwadi chekuti girazi fiber geogrid muasphalt layer haizogurwe kubva kune asphalt composite zvinhu, asi yakanyatsobatanidzwa.Iyo geogrid ichaiswa pane yakapfava yezasi inotakura layer zvinoenderana neyakagadzirirwa saizi yekupamba.Muzadzisi wekosi yepasi yepamusoro haafaniri kubaya marara egeogrid.Kana geogrid yaiswa, sipidhi yemhepo inokwira zvakanyanya kuti iyambuke pakati pepakati pemuchinjiko.Geogrid inoradzikwa kureba.Kuiswa kunofanira kusimbiswa kudzivirira kuunyana, kumonyoroka kana kupinza.
Iyo geogrid yakabatana yakatwasuka nenzira inopindirana, uye saizi yekutasva haina kupfuura 20cm.Mushure mekunge geogrid yaiswa, iyo manyorero yekuisa yekumusoro layer yekuzadza ichapedzwa nekukasira kudzivirira kuratidzwa kuzuva gore rose.Wobva waita kutakura zvinhu zvemuchina, kuyera uye kutenderedza.Iyo mechanical paving uye rolling inoitwa kubva kumativi ose maviri kusvika kumativi ose, uye kutenderera kunoitwa kubva kumativi ose kusvika kumativi ose maviri, uye compactness inochengetwa kuti iwane kubviswa kwakafanana.
2、 Geogrid ine simba rekusimba resimbi yakapfava
Iyo geogrid inoronga patsva cheni refu hydrocarbon mamorekuru epolymer mumutsara wakatwasuka uchitevedza nzira inotatamuka kuburikidza neyakasiyana tekinoroji maitiro.Simba rekusunga pakati pecheni dzemamorekuru rinosimbiswa zvakanyanya, saka rine simba repamusoro rekusimba uye kureba kwakadzika.Semuyenzaniso, kusimba kwesimba kunosvika 5-10 nguva dzakakwirira kupfuura iyo isati yatambanudzwa, uye elongation inongova 10% - 15% yakakwirira kupfuura iyo isati yatambanudza.Simba rinopindirana rezvikamu mugridhi rinowedzera, uye friction coefficient inowedzera zvakanyanya.Zvinogona kutaurwa kuti pakati peakawanda geosynthetics, simba rekusimba re geogrid ndiro rakakwirira pasi pedambudziko rakafanana, uye simba rayo rekusimba riri pedyo neresimbi nyoro.Pamusoro pesimba rayo rakasimba rekusimba, iyo geogrid inewo kusimba kwakanaka, nekuti iyo geogrid zvinhu zvakagadzirwa nepamusoro-density polyethylene kana polypropylene plastiki seyakanyanya mbishi zvinhu, uye ine anti-kuchembera zvinowedzera seUV uye kabhoni dema, inogona kudzivirira kukukurwa kwezvinhu zvinonyungudutsa zvemuchadenga zvakaita seasidhi, alkali, munyu, doro, peturu uye UV.Zvinoenderana nedata rakakodzera, hupenyu hwesevhisi yegeogrid inogadzirwa nevagadziri vegeogrid inogona kusvika makore zana nemakumi maviri pasi peyakajairwa tembiricha mamiriro uye dhizaini inotenderwa mutoro.Ehe, chikonzero nei ma geogrids achishandiswa zvakanyanya ndechekuti ma geogrids anotsanangurwa pazasi ane hunhu hwakanakisa.Muchirongwa chekunakisa kwemateru, purasitiki geocell yemugadziri wegeogrid, mushure mekunge geocell yawedzerwa nekuvhurwa, inopa muzinga wehutatu-dimensional geocell, uye inozadza geocell nevhu nematombo kana kongiri zvinhu kuti zvigadzire chivakwa chine yakasimba lateral kuzvidzora uye. kuoma kukuru kuumba kugadzikana mhedzisiro pamateru.Inogona zvakare kurima zvimwe zvinomera, kana zvikwenzi zvidiki uye zvimwe zvinomera mugeogrid, kugadzira yakatarisana negirazi fiber grid ndiyo huru geosynthetic zvinhu, ine kuita kwakafanana uye mhedzisiro kana ichienzaniswa nezvimwe zvinhu zve geosynthetic.Girazi fiber grid inowanzoshandiswa sekusimbisa kune yakasimbiswa zvivakwa zvevhu kana zvinhu zvinoumbwa
