I-Soil Nailing

Ukuphakamisa umhlabathi kungumkhuba wokuvuselela nokuzinzisa umhlaba okusebenzisa ukufakwa kwemiyalo yensimbi enedatha encane noma ama-reinforcing bars emithini yomhlaba, eqiniswa ngokuqhuba ukuze kwakhiwe isakhiwo somhlaba oqinisiwe. Le ndlela ye-geotechnical ibaluleke kakhulu ku-engineering yeziqalo zanamuhla nokuthuthukiswa komhlaba, ihlinzeka ngezixazululo ezikahle zokuzinza kwemifantu, ukweseka ukumba, nokuvuselela umhlaba ezimweni ezinzima zomhlabathi. Le ndlela iye yathandwa kakhulu emaphrojekthini okwakha adinga ukwesekwa komhlaba okwethulwa okwesikhashana noma okungapheli, ikakhulukazi lapho izinhlelo ze-piling noma izisekelo ezijulile zingase zibe yindleko ezingafanele noma ezingakaze zisebenze. Ukuphakamisa umhlabathi kusebenzelana nokuqinisa amandla okuphazamiseka komhlabathi okuzungezile okutholakala emiyalweni efakiwe, kwakha isakhiwo sokugcina isisindo esingakwazi ukumelana nengcindezi yomhlaba ehambelayo futhi sigcine ukuzinza ezinzululweni eziphakeme noma ezikhaleni ezivertical. Inqubo yokuphakamisa umhlabathi ivamise ukuqala ngokuqhubekayo ekuhambeni komhlaba ngokwaziswe kumangqamuzana kanye nasemigangatho, ilandela ukufakwa kwamabhakede ensimbi noma imiyalo nokufaka umjovo wegrout ophakeme ukuhlanganisa imiyalo nomhlaba ozungezile. Ubude bemiyalo ejwayelekile buhamba phakathi kuka-5 no-15 amamitha kuye ngobukhulu bokumba kanye nezimo zomhlaba, lapho imingcele ivamise phakathi kuka-1 no-2.5 amamitha kokubili phezulu nangokwejwayelekile. Uhlelo lwezinhlelo, olungase luhlanganise i-shotcrete, umgogodla wensimbi, noma amaphaneli e-concrete aqinisiwe, lufakwa njengoba ukumba kuqhubeka ukuze kuhlanganyelwe izinsiza futhi kuqinise imigwaqo. Ukuphakamisa umhlabathi kusebenze kahle ezithombeni ezinzima zokusebenzisa i-clays, umhlaba olungiselelwe, kanye nezindonga ezishisayo, lapho amandla afanele nokubamba kungatholakala phakathi kwemiyalo nomasipala womhlaba. Le ndlela ilungele ukuguquguquka ezimweni zomhlaba ezahlukahlukene nasemaphakathini alandelanayo, yenze kube yisixazululo esisebenziseka kalula ezinselelweni ezinzima zokuqinisa izisekelo ezindaweni zasemadolobheni nasezindaweni ezifile zokwakha. Izicelo zokuphakamisa umhlabathi zifaka izinkalo eziningi okubandakanya ukwesekwa kwemifantu okwesikhashana ngesikhathi sokumba kwezindaweni, ukuzinza okungapheli kwemigwaqo nokwakha, ukwesekwa kwemifantu ekhona, kanye nokuvuselela izifunda eziphakeme eziyingozi. Emaphrojekthini ezisekelo ezijulile nasezindaweni ezisemhlabeni, ukuphakamisa umhlabathi kuhlinzeka ngesisekelo esikhulu ngesikhathi sokumba kwepile cap nokwakha indawo, kuvumela ukufinyelela komhlaba okuphathwayo nokuphepha. Le ndlela ibaluleke kakhulu ku-engineering ye-geotechnical lapho ingaxubana nezinye izindlela zokuthuthukiswa komhlaba ezifana ne-micropiling, i-jet grouting, noma i-ground anchoring ukuze kwakhiwe izixazululo ezihlanganisiwe zezakhiwo. Ukuphakamisa umhlabathi kunezithako ezinkulu ezimnandi mayelana nesivinini sokufaka, ukusizakala kwezimali uma kuqhathaniswa nezindonga ezijwayelekile, ukuphazamiseka okuncane kwemhlaba, kanye nokwenziwa kweminye imikhawulo yesayithi ekhona. Imishini nezinto ezidingekayo—kubandakanya ama-drilling rigs, ama-grouting pumps, ama-grout mixers, insimbi yokwakha, kanye nezinhlelo zokufaka—zitholakala kalula ngeziphathimandla nezinkampani ezimisiwe ezigxile emsebenzini wokuvuselela umhlaba nezokwakha.
