Ukugeleza kwenqubo yokwakha:
Ukulungiswa kokwakha (ukuthutha nokubeka impahla) → ukwelashwa kwesisekelo (ukuhlanza) → ukubeka i-geogrid (indlela yokubeka nobubanzi obudlulele) → isigcwalisi (indlela nosayizi wezinhlayiyana) → igridi egoqayo → ukubeka igridi ephansi.
Indlela yokwakha:
① Ukwelashwa okuyisisekelo
Okokuqala, ungqimba olungezansi kufanele lulinganiswe futhi lugoqwe.Ukucaba akumele kube kukhulu kuno-15mm, futhi ukubumbana kuzohlangabezana nezidingo zokuklama.Indawo engaphezulu akumele ibe nama-protrusions aqinile njengetshe le-block.
② I-Geogrid laying
A. Lapho ugcina futhi ubeka i-geogrid, gwema ukuchayeka elangeni nokuchayeka isikhathi eside ukuze ugweme ukonakala kokusebenza.
b.I-laying izoba yi-perpendicular to line direction, i-lapping izohlangabezana nezidingo zemidwebo yokuklama, futhi uxhumano kufanele luqine.Amandla oxhumano esiqondisweni sokucindezeleka akumele abe ngaphansi kwamandla we-design tensile wento, futhi ubude obugqagqene akumele bube ngaphansi kwama-20 cm.
c.Izinga le-geogrid lizohlangabezana nezidingo zemidwebo yedizayini.
d.Ukwakhiwa kufanele kuqhubeke ngaphandle kokuhlanekezela, ukushwabana nokugqagqana.Igridi izoqiniswa ukuze ikwazi ukuthwala amandla.Igridi izoqiniswa ngesandla ukuze ifane, isicaba futhi isondele endaweni engaphansi.Igridi kufanele ihlanganiswe nezikhonkwane nezinye izilinganiso.
e.Ku-geogrid, isiqondiso sembobo ende sizohambisana nesiqondiso sesigaba esiphambanayo somugqa, futhi i-geogrid izoqondiswa futhi ilethwe.Ukuphela kwe-grating kufanele kuphathwe ngokuvumelana nomklamo.
f.Gcwalisa i-geogrid ngesikhathi ngemva kokugandaya, futhi isikhawu ngeke sidlule ku-48h ukugwema ukuchayeka elangeni okuqondile.
③ Isigcwalisi
Ngemva kokuba i-grating igandayiwe, izogcwaliswa ngesikhathi.Ukugcwaliswa kuzokwenziwa ngokulinganayo ngokomgomo othi "izinhlangothi ezimbili kuqala, bese kuba phakathi".Akuvunyelwe ngokuphelele ukugcwalisa maphakathi ne-embankment kuqala.I-filler ayivunyelwe ukuthululwa ngokuqondile ku-geogrid, kodwa kufanele yehliswe endaweni egandayiwe yenhlabathi, futhi ukuphakama kokuthulula akubi ngaphezu kwe-1m.Zonke izimoto nemishini yokwakha akufanele zihambe ngqo ku-geogrid egandayiwe, kodwa kuphela eduze nonqenqema.
④ Goqa i-grille
Ngemva kokuba ungqimba lokuqala lokugcwalisa lufinyelele ugqinsi olunqunywe kusengaphambili futhi lugoqwe ekuhlanganisweni komklamo, igridi izogoqelwa emuva ngo-2m futhi iboshwe ungqimba lwangaphambili lwe-geogrid, futhi i-geogrid izosikwa ngesandla futhi ifakwe ihange.Uhlangothi lwangaphandle lwesiphetho somqulu kufanele lugcwaliswe emuva nge-1m ukuze kuvikelwe igridi futhi kuvinjwe umonakalo owenziwe umuntu.
⑤ Ungqimba olulodwa lwe-geogrid luzogandaywa ngokwendlela engenhla, kanti ezinye izendlalelo ze-geogrid zizogandaywa ngendlela efanayo.Ngemuva kokuthi igridi igandayiwe, ukugcwaliswa koqweqwe olungaphezulu kuzoqalwa.
Izinyathelo zokuphepha zokwakha:
① Isiqondiso samandla amakhulu wegridi kufanele sihambisane nesiqondiso sengcindezi enkulu.
② Izimoto ezinzima akufanele zishayelwe ngokuqondile ku-geogrid egandayiwe.
③ Inani elinqunyiwe kanye nenani lokuthunga le-geogrid lizoncishiswa ukuze kugwenywe ukungcola.
④ Ngesikhathi sokwakha ngezikhathi ezibandayo, i-geogrid izoba nzima, futhi kulula ukusika izandla nokusula amadolo.Naka ukuphepha.
