Amathambo e-Anchor (Amanzi)

Ishubhu esinamathread elicindezela izinsiza ezinhle kakhulu ezisetyenziswa ngaphakathi kwezingxenye zokufaka izimbobo zokuzilandelayo (SDA) ukuze kuhanjiswe umhlaba ophakeme kanye nokuzinza kwemizila ezindaweni ezigcwele izinselele ze-geotechnical. Lezi zinsiza ezikhethekile, ngokuvamile zenziwe ngezinto ezinegesi ezibuthakathaka zensimbi ephezulu enokudlula okulungile ubude bazo, zisebenza njengamalungu amakhulu okucindezela adlulisa imithwalo yesakhiwo ngqo emhlabeni osezingeni eliphezulu naphakathi kwezindonga. Ngesikhathi sokufakwa kwezingxenye zokuzilandelayo, izinsiza ezinamathread zibhujiswa kanye nezilungiswa zifakwa ngaphakathi kwemibobo kusetshenziswa ubuchwepheshe obuphambili be-SDA, kunciphisa isidingo sokukhipha izikhali ezahlukene futhi kudala ubuhlobo obuqhubekayo phakathi kwezinsiza, ikholomu yokugcwaliswa, kanye nomhlabathi ozungezile. Ubuhlobo bamathread bunomsebenzi ophindwe kabili: buvumela ukuhlanganiswa kwemishini ne-matrix ye-grout ye-cementitious phakathi kwemisebenzi yokugcwaliswa k压力 futhi bunikeza amandla okuthwala aphezulu ngokwandisa isikhala sezingxenye, kuqinisekisa ukuhamba kwemithwalo okukahle ngaphezu kwempilo yokwakha ende. Ukufakwa kwezinsiza ezinamathread kudinga imishini yokubhoboza ekhethekile ekwazi ukcutheka kanye nokugcwaliswa ngesikhathi esifanayo phakathi kwezixazululo zomhlaba ezahlukene, kufaka phakathi amagayidi alula, ama-berfoma, nezitsha eziphukile. Ukukhetha ububanzi bezinsiza, ubude, kanye nezikhala kuncike emabhukwini aphelele e-geotechnical ahlukanisa ama-profile emhlaba, abhalela amandla okushayisa, futhi asungula imithwalo yokwakha ngezinsiza. Izimo zomhlaba ezitholwa zifaka phakathi izinto ezithambile ezihlanganisa iklayi nephasi eline-oligo, ezinezinga eliphansi lokuthwala ukuya kokuphishekela okuphezulu, ama-gravels anokugudlukela, i-granite engxenyeni, kanye nezakhiwo eziphukile. Kwi-overburden ethambile, ugqoka olufushane olunamathafa amabili luveza izidingo; emashumini aphakeme, izinsiza ezinde ezinezikhala ezinkulu zenza umsebenzi ophumelelayo. Ingcindezi yokugcwaliswa kanye nomthamo kugcinwa ngendlela eqondile ukuze kufezwe ukuvuleka kahle phakathi komhlaba-umbobo-ukugcwaliswa kanti lokhu kugwenya ukungezelela okukhulu noma ukuphula umhlaba ezindaweni ezibucayi eziseduze nezakhiwo ezikhona. Izinsiza ezinamathread zisebenza ezintweni ezihlukahlukene ezihambelana nezokwakha ezivusa ukujula kwemizila emakhasi nakuma-dihapharam, ukwakhiwa okujulile kwezinsiza zomlando noma izakhiwo ezibucayi, ukweseka okuphakeme kwezimfunda ezijulile nezindonga ze-diaphragm, kanye nokuqiniswa kwemisebenzi yokumbiwa phansi nezinsiza. Emisebenzini yokubuyisela i-landsli, imigqa yemithwalo eminingi ivikela ukuhamba kokuqhubekayo komhlaba ngokusabalalisa ukucindezela ukujula ezindaweni eziqinile ngaphansi kobubanzi bokuphuma. Ukukhazana kokweluleka kwemithombo yeziqheshe nezindonga zokugcina kuzuza ekuthwaleni amandla aphezulu kanye nemikhuba yokubamba imithwalo eqinile ye-grouted threaded anchor systems. Abaqashi kanye nemisebenzi yeziqhubi esebenzisa ubuchwepheshe bokufaka izimbobo zokuzilandelayo bathola izinzuzo zokuncintisana ngokunciphisa isikhathi sezinhlelo uma kuqhathaniswa nemithomondzwane ye-drilling ne-grouting, kuncipha ukuhamba kwemfucuza ezindaweni zomhlaba ezithintekayo, futhi kuthuthukisa ukuqina ezimweni zomhlaba ezijolile lapho okukhuluma kudinga impumelelo. Ukuhlanganiswa kwezinsiza ezinamathread ngaphakathi kwezingxenye zokufaka izimbobo zokuzilandelayo kubonisa isixazululo esiphumelelako, esihlelwe kahle sokuphakamisa umhlaba okhona lapho ukwesekwa kwesikhashana noma sokubolekwa kuncishisiwe futhi ukwehluka kwezintaba kudinga izindlela zokufaka ezithathekayo nezenzekelayo ezihambelana nezimo zaphansi ezitholwe ngesikhathi sokwakha.
