Isishwankathelo seeBhari zeNsimbi ezingenanto zeAnchor
Iibha zentsimbi ezingenanto ezifakwe kwi-anchor ziveliswa ngamacandelo anobude obuqhelekileyo obuyi-2.0, 3.0 okanye 4.0 m. Ububanzi obuqhelekileyo bangaphandle beebha zentsimbi ezingenanto buqala kwi-30.0 mm ukuya kwi-127.0 mm. Ukuba kuyimfuneko, iibha zentsimbi ezingenanto ziyaqhubeka kunye neenati zokudibanisa. Iindidi ezahlukeneyo zeebhithi zokubhola ezizincamayo zisetyenziswa ngokuxhomekeke kuhlobo lomhlaba okanye ubunzima bamatye. Ibha yentsimbi engenanto ingcono kunebha eqinileyo enendawo efanayo yokunqumla ngenxa yokuziphatha kwayo okungcono ngokwesakhiwo ngokubambelela, ukujikeleza kunye nokuqina kokugoba. Isiphumo kukuba i-buckling ephezulu kunye nokuzinza kwe-flexural kwinani elifanayo lentsimbi.

Usetyenziso lweeNtonga zeAnchor zokuzigqobhoza
Kwiminyaka yakutshanje, ngenxa yokwanda kwemfuno yenkxaso ye-geotechnical, izixhobo zokumba ziye zahlaziywa kwaye zaphuhliswa rhoqo. Kwangaxeshanye, iindleko zomsebenzi kunye nerenti ziye zanda, kwaye iimfuno zexesha lokwakha ziye zanda kakhulu. Ukongeza, ukusetyenziswa kweentonga ze-anchor ezingenanto zokuzibhoboza kwiimeko zejoloji ezinokuthi zidilike kunemiphumo emihle yokuzibopha. Ezi zizathu zikhokelele ekusetyenzisweni okubanzi kweentonga ze-anchor ezingenanto zokuzibhoboza. Iintonga ze-anchor ezingenanto zokuzibhoboza zisetyenziswa kakhulu kwezi meko zilandelayo:
1. Isetyenziswa njengenduku ye-anchor exinezelekileyo: isetyenziswa kwiimeko ezifana ne-slopes, ukumba ngaphantsi komhlaba, kunye ne-anti floating ukuze kuthathelwe indawo iintambo ze-anchor. Iinduku ze-anchor ezingenanto zigrunjwa ngokwazo ukuya kubunzulu obufunekayo, emva koko kwenziwa i-grouting yokugqibela. Emva kokuqina, kufakwa uxinzelelo;
2. Zisetyenziswa njengee-micropiles: Iintonga ze-anchor ezingenanto zingagrunjwa kwaye zibekwe phantsi ukuze zenze ii-micropiles, ezisetyenziswa rhoqo kwiziseko zenqaba yesikhululo samandla omoya, iziseko zenqaba yokudlulisela, iziseko zokwakha, iziseko zeenqwaba zodonga ezigcinayo, iziseko zeenqwaba zebhulorho, njl.njl.;
3. Isetyenziselwa izikhonkwane zomhlaba: isetyenziswa rhoqo ekuxhaseni ukuthambeka, ithathe indawo yeentonga zentsimbi zesiqhelo, kwaye ingasetyenziselwa nasekuxhaseni ukuthambeka okunzulu komngxuma wesiseko;
4. Isetyenziselwa izikhonkwane zamatye: Kwezinye iindawo ezisematyeni okanye kwiitonela ezinemozulu embi okanye uphuhliso oludibeneyo, iintambo ze-anchor ezizigqobhozayo zingasetyenziselwa ukubhola kunye nokudibanisa iibhloko zamatye ukuze zidibanise kunye ukuphucula uzinzo lwazo. Umzekelo, iindawo ezisematyeni zeendlela ezinkulu kunye neekaloliwe ezinokuthi zidilike zinokuqiniswa, kwaye iishedi zepayipi eziqhelekileyo nazo zingatshintshwa ukuze ziqiniswe kwiindawo ezivulekileyo zeetonela;
5. Ulawulo olusisiseko lokuqinisa okanye lwentlekele. Njengoko ixesha lokuxhasa inkqubo yokuxhasa ye-geotechnical yokuqala lisanda, ezi zakhiwo zokuxhasa zinokudibana neengxaki ezithile ezifuna ukuqinisa okanye unyango, ezinje ngokuguqulwa kwethambeka lokuqala, ukuhlaliswa kwesiseko sokuqala, kunye nokuphakama komphezulu wendlela. Iintonga zeankile ezingenanto zingasetyenziselwa ukugqobhoza kwithambeka lokuqala, isiseko, okanye umhlaba wendlela, njl.njl., ukuze kugrunjwe kwaye kudityaniswe iintanda, ukuthintela ukwenzeka kweentlekele ze-geological.
