Indlela yokwakha ye-geogrid yepulasitiki yendlela eyodwa

1, Uma isetshenziselwa ukwakhiwa kwe-subgrade kanye nokugandaywa kwezinyawo, umbhede wesisekelo uzombiwa, kuhlinzekwe umcamelo wesihlabathi (onomehluko wokuphakama ongeqile ku-10 cm), ugingqelwe endaweni yesikhulumi, bese kubekwa i-geogrid.Izikhombisi-ndlela ze-longitudinal ne-axial kufanele zihambisane nezikhombisi-ndlela ezithwala ingcindezi.Ukujula komugqa kufanele kube ngu-15-20 cm, futhi isiqondiso esiphambene kufanele sibe ngu-10 cm.Ukugqagqana kuzoboshwa nge-tape yepulasitiki, futhi ku-geogrid egandayiwe, izipikili ezimise okwe-U zizosetshenziswa ukuze zilungiswe phansi njalo ngo-1.5-2m.I-geogrid egandayiwe izogcwaliswa ngemuva komhlabathi ngesikhathi esifanele, futhi inani lezendlalelo ze-geogrid lizoncika ezimfuneko zobuchwepheshe.

I-2, Uma isetshenziselwa izindonga zokugcina umhlaba eziqinisiwe, ukusatshalaliswa kokwakhiwa kungokulandelayo:

1. Isisekelo sizosethwa futhi sakhiwe ngokuvumelana nohlelo oluklanyelwe udonga.Lapho kukhethwa amaphaneli kakhonkolo aqiniswe ngaphambili, ngokuvamile asekelwa esisekelweni sikakhonkolo esinogqinsi luka-12-15cm.Ububanzi bawo akumele bube bukhulu kuno-30cm, ukujiya kwawo akumele kube ngaphansi kuka-20cm, futhi ukujula kwawo okungcwatshwe akumele kube ngaphansi kuka-60cm ukuvimbela umthelela wesithwathwa esishisayo esisekelweni.

2. Ukulinganisa isisekelo sodonga, ukumba nokulinganisa ngokuvumelana nezidingo zokuklama.Inhlabathi ethambile idinga ukuhlanganiswa noma ukushintshwa, futhi ihlanganiswe kubukhulu obudingekayo, okufanele budlule kancane ububanzi bodonga;

3. Lapho ubeka ukuqinisa, isiqondiso esiyinhloko samandla sokuqiniswa kufanele sibe yi-perpendicular ebusweni bodonga futhi silungiswe ngezikhonkwane;

4. Ukugcwalisa udonga, ukugcwaliswa kwemishini kuzosetshenziswa, futhi ibanga phakathi kwesondo nokuqiniswa kuzogcinwa okungenani u-15 cm.Ngemuva kokuhlanganisa, ungqimba lomhlabathi kufanele lube ngu-15-20 cm ubukhulu;

5. Ngesikhathi sokwakhiwa kodonga, udonga kufanele luboshwe nge-geotextile ukuvimbela ukuvuza kwenhlabathi.
