Ukusetyenziswa kwe-geogrid yentsimbi-plastiki ekuqiniseni nasekukhuliseni i-subgrade

1. Umgaqo wokuqinisa

• Yandisa uzinzo lomhlaba
  • Amandla okutsalwa kwe-geogrid yentsimbi-yeplastiki athwalwa yintambo yentsimbi enamandla aphezulu elukiweyo nge-warp kunye ne-weft, evelisa i-modulus yokutsalwa ephezulu kakhulu phantsi komthamo omncinci wokutsalwa. Isiphumo sokusebenzisana kweembambo ezinde nezinqamlezileyo sinokunika ukusebenza okugcweleyo kwisiphumo sokutshixa segridi emhlabeni, sithintele ngokufanelekileyo ukufuduka komhlaba ecaleni kwaye sonyuse uzinzo lulonke lwe-subgrade. Kufana nokongeza isakhelo esiqinileyo kumhlaba okhululekileyo, ukuze umhlaba ungabi lula ukuwuguqula.
• Ukuphucula amandla okuthwala umthwalo
  • I-warp kunye ne-weft yeengcingo zentsimbi zeembambo ezinde nezinqamlezileyo zilukwa zibe yinethi, kwaye umaleko wokusonga wangaphandle wenziwa ngaxeshanye. Ingcingo yentsimbi kunye nomaleko wokusonga wangaphandle unokulungelelanisa, kwaye ulwandiso lokusilela luphantsi kakhulu (lungadluli kwi-3%). Iyunithi yoxinzelelo oluphambili yingcingo yentsimbi, kwaye ukuqhekeka kuphantsi kakhulu. Ezi mpawu zivumela i-geogrid yentsimbi-plastiki ukuba ithwale amandla amakhulu okutyhala kwi-subgrade, yabelane ngoxinzelelo lwezithuthi kunye neminye imithwalo kwi-subgrade, ngaloo ndlela iphucula amandla okuthwala kwe-subgrade, njengokongeza amanqaku amaninzi okuxhasa kwi-subgrade ebuthathaka.
• Yandisa i-coefficient yokungqubana
  • Ngokusebenzisa unyango lomphezulu weplastiki kwinkqubo yemveliso, iipateni ezirhabaxa ziyacinezelwa, nto leyo ephucula uburhabaxa bomphezulu wegridi kwaye iphucule umlinganiselo wokungqubana phakathi kwegridi yentsimbi-yeplastiki nomhlaba. Oku kunceda ukubopha ngcono igridi nomhlaba, okuvumela igridi ukuba idlale indima yokuqinisa esebenza ngakumbi kwaye ithintele ukuhla komgangatho ekutyibilikeni phantsi komthwalo.

2. Ukusetyenziswa okuthe ngqo ekuqiniseni nasekukhuliseni umgangatho ongaphantsi

• Ukusetyenziswa kwesiphambuka se-subgrade entsha nendala
  • Nciphisa ukuhlalisana okungalinganiyo：Kwiprojekthi yokwandiswa nokwakhiwa kwakhona kwendlela endala, kulula ukwenzeka ukungalingani kwindawo edibana kuyo indlela entsha nendala. I-geogrid yentsimbi-plastiki inamandla okutsalwa, ibekwe phakathi kwendlela entsha nendala, inokuphucula uzinzo lwendlela xa idibana iindlela ezintsha nezindala, inciphise okanye ithintele ngempumelelo isiganeko sokuqhekeka okubangelwa kukungalingani kokuhambelana kwendlela entsha nezindala, yenze iindlela ezintsha nezindala zibe zizonke, iqinisekise uzinzo lwendlela。
  • Unxibelelwano oluphuculweyo：Ingadibanisa ngcono umhlaba we-subgrade entsha nomhlaba we-subgrade endala, ukuze ii-subgrade ezintsha nezindala zikwazi ukuthwala amandla kunye. Umzekelo, xa indlela endala inwetshiwe, i-geogrid yentsimbi-yeplastiki ibekwa kwinqanaba lokudibana kwe-roadbed entsha nendala, kwaye iimbambo zayo ezinde nezithe tye zinokutshixwa ngokuqinileyo nomhlaba kumacala omabini, ukuze kuphuculwe amandla okuthwala kunye nokuzinza kwe-roadbed entsha nendala, kwaye kuthintelwe iingxaki ezinje ngokuqhekeka okanye ukudilika ngexesha lokusetyenziswa okulandelayo。
• Ukwandisa inxalenye yokuqinisa i-subgrade
  • Amandla okucheba aphuculweyo：Kwi-subgrade ebanzi, i-geogrid yentsimbi-plastiki inokuphucula amandla okucheba komhlaba ongaphantsi komhlaba. Xa i-subgrade iphantsi kwamandla angqindilili afana nokuqhuba imoto, i-grille inokumelana nala mandla okucheba angqindilili kwaye ithintele ukungaphumeleli kokucheba komhlaba ongaphantsi komhlaba. Umzekelo, kwiiprojekthi zokwandisa iindlela ezinkulu, ukubeka i-geogrid yentsimbi-plastiki kwi-subgrade ebanzi kunokuphucula kakhulu ukumelana nokucheba komhlaba ongaphantsi komhlaba kwaye kuqinisekise ukhuseleko kunye nokuzinza kwesakhiwo se-subgrade ebanzi。
  • Ukuthintela ukufuduka ecaleniNgenxa yokusebenza kakuhle kokutsalwa kwe-geogrid yentsimbi-plastiki, inokuthintela ngokufanelekileyo ukuguquka kwe-lateral yokuzaliswa kwe-subgrade. Ngexesha lenkqubo yokwakha yokwandisa i-subgrade, umhlaba ozaliswayo unokufuduselwa ngaphandle phantsi kwesenzo sobunzima bomzimba kunye nomthwalo wangaphandle. I-geogrid yentsimbi-plastiki inokubonelela ngokuthintela ecaleni, igcine imo kunye nobukhulu be-subgrade, kwaye iphephe ukudilika kwe-subgrade slope.
