I-Geosynthetics luhlobo olutsha lwezixhobo zobunjineli be-geotechnical, ezinokuthi zenziwe ngeepolymers zendalo okanye ezenziwe ngabantu (iplastiki, ifayibha yemichiza, irabha eyenziweyo, njl.njl.) kwaye ibekwe ngaphakathi, phezu komhlaba okanye phakathi kwamaleko omhlaba ahlukeneyo ukomeleza okanye ukukhusela umhlaba. umhlaba.
Okwangoku, i-Geotextiles isetyenziswe ngokubanzi kwiindlela, kwiindlela zomzila, ukugcinwa kwamanzi, amandla ombane, ukwakhiwa, amachweba, imigodi, imboni yezempi, ukukhuselwa kokusingqongileyo kunye nezinye iindawo.Iindidi eziphambili ze-geosynthetics ziquka i-geotextiles, i-geogrids, i-geogrids, i-geomembranes, i-geogrids, i-geo composites, i-bentonite mats, i-geological slopes, i-geo foam, njl. Kwizicelo zobunjineli, i-Geotextiles ingasetyenziswa yodwa okanye idityaniswe ne-geogrids, i-geomembranes kunye nezinye, imathiriyeli edibeneyo ye-geo.
Okwangoku, imathiriyeli ekrwada ye-geotextiles ubukhulu becala ziintsinga zokwenziwa, ezona ziqhele ukusetyenziswa ziintsinga zepolyester kunye neefiber zepolypropylene, zilandelwa ziintsinga zepolyamide kunye ne-polyvinyl acetal fibers.
Ifayibha yePolyester ineempawu ezilungileyo zomzimba nezomatshini, ukuqina okugqwesileyo kunye neempawu ezirhubuluzayo, indawo ephezulu yokunyibilika, ukumelana nobushushu obuphezulu, ukumelana nokwaluphala, itekhnoloji yemveliso evuthiweyo kunye nesabelo esikhulu sentengiso.Izinto ezingeloncedo yi-hydrophobicity engalunganga, kulula ukuqokelela i-condensate yezixhobo zokugquma i-thermal, ukusebenza kakubi kobushushu obuphantsi, kulula ukubetha, ukunciphisa amandla, i-asidi embi kunye nokuxhathisa kwe-alkali.
Ifayibha yePolypropylene ine-elasticity elungileyo, kwaye ukunwebeka kwayo kwangoko kunye nokomelela kwayo kungcono kune-polyester fiber.I-asidi elungileyo kunye nokumelana ne-alkali, ukuxhathisa ukunxiba, ukumelana nokungunda kunye nokumelana nobushushu obuphantsi;Ine-hydrophobicity elungileyo kunye nokufunxwa kwamanzi, kwaye inokudlulisela amanzi kumphezulu ongaphandle kunye ne-fiber axis.Ukuxinana kuncinci, kuphela i-66% yefiber yepolyester.Emva kwamaxesha amaninzi oyilo, i-fine denier fiber ene-compact structure kunye nokusebenza okuphezulu kunokufumaneka, kwaye emva kwenkqubo yokomeleza, amandla ayo angaphezulu.Into engalunganga kukumelana nobushushu obuphezulu, indawo yokuthambisa ye-130 ~ 160 ℃, ukunganyangeki kokukhanya, kulula ukubola elangeni, kodwa i-UV absorbers kunye nezinye izongezo zingongezwa ukuze zikwazi ukumelana ne-UV.
Ukongeza kwezi ntsinga zingentla, ijute fibers, polyethylene fibers, polylactic acid fibers, njl njl.Iintsinga zendalo kunye neentsinga ezikhethekileyo ziye zangena ngokuthe ngcembe kwiinkalo ezahlukeneyo zesicelo se-geotextiles.Ngokomzekelo, imicu yendalo (i-jute, i-fiber shell ye-coconut, i-bamboo pulp fiber, njl.) isetyenziswe kwi-subgrade, i-drainage, ukukhusela ibhanki, ukuthintela ukukhukuliseka komhlaba kunye nezinye iindawo.
Uhlobo lweGeotextile
I-Geotextile luhlobo lwe-geotextile ekwazi ukuvunywa eyenziwe ngeentsinga zepolymer ngokucinezela okushushu, isamente kunye nokuluka, okwakwaziwa ngokuba yi-geotextile, kubandakanya ukuluka kunye nee-nonwovens.
Iimveliso ezinithiweyo ze-Geotextile ziquka ukunitha (i-weave ecacileyo, i-weave engqukuva), ukunitha (i-plain weave, twill), ukunitha (i-warp knitting, ukunitha inaliti) kunye nezinye iinkqubo zemveliso.
I-geotextiles engabonakaliyo ibandakanya iinkqubo zokuvelisa ezifana ne-mechanical reinforcement method (indlela ye-acupuncture, indlela yokubhoboza amanzi), indlela yokudibanisa imichiza (indlela yokutshiza iglue, indlela yokungena), indlela yokudibanisa eshushu (indlela eshushu yokuqengqeleka, indlela yomoya oshushu), njl.
I-geotextile ephothiweyo yeyokuqala eyaziswa nge-geotextile, kodwa inemida yeendleko eziphezulu kunye nokusebenza kakubi.Ngasekupheleni kwee-1960, i-geotextiles engalukiweyo yaziswa.Ekuqaleni kweminyaka yee-1980, iChina yaqala ukusebenzisa le nto kumaqumrhu obunjineli.Ngodumo lwenaliti ephothiweyo yeenonwovens kunye ne-spunbonded nonwovens, ibala lesicelo le-nonwovens libanzi kakhulu kunelo le-geotextiles elikhubazekileyo, kwaye liphuhliswe ngokukhawuleza.I-China iye yaphuhla yaba ngumvelisi omkhulu we-Nonwovens emhlabeni, kwaye ngokuthe ngcembe isiya kumvelisi onamandla.
I-Geotextile filtration, ukunkcenkceshela, ukwahlula, ukuqinisa, ukuthintela ukubola, ukuthintela usulelo, ubunzima obulula, amandla aphezulu, ukungena kakuhle kunye nokumelana nokushisa okuphantsi, ukumelana nokubanda, ukumelana nokuguga, ukuxhathisa ukubola, ukuguquguquka njalo njalo, zisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo.Ubomi bomsebenzi ogqwesileyo wemetropolis okwethutyana bubonisa ngokupheleleyo ukuba alukho olunye usulelo.
Kutheni le nto kufuneka kwenziwe ubalo-mali oluthile ngaphambi kokwakhiwa kwe-geotextile?Iingcali ezininzi ze-novice azicaci kakuhle malunga nokubalwa kwe-geotextiles ngaphambi kokwakhiwa.Kuxhomekeke kwikhontrakthi yokucwangcisa kunye nendlela yokucaphuna yokwakha.Ngokuqhelekileyo, ibalwa ngokwendawo.Kufuneka ubeke ingqalelo kwi-slope.Kufuneka uyiphindaphinde nge-slope coefficient.
