Sibutsetelo se-T76 Full Threaded Steel CORKING ROCK BOLT
Ama-anchors wokuzibandakanya aluhlobo olukhethekile lwamahange. I-anchor yokuzibamba iqukethe umhlatshelo omncane wokudla, ibha yensimbi engenalutho yobubanzi obungaphandle nobungaphakathi kanye namantongomane ahlanganayo. Umzimba we-anchor wenziwa ngeshubhu lensimbi engenalutho enentambo eyindilinga yangaphandle. I-Tube yensimbi inomhlatshelo omncane ekugcineni okukodwa kanye ne-nati ehambisanayo enepuleti lokuphela lensimbi. Izikhonkwane zokuzibandakanya zisetshenziswa ngendlela engekho lutho lwensimbi (induku) enokudla okuhambisanayo komhlatshelo ngaphezulu kwayo esikhundleni se-classic drill bit.

Inzuzo nokusetshenziswa kokuzimba izinduku zehange
Umsebenzi we-hollow groung spiral anchor induku uyamangalisa, ngakho-ke futhi ibizwa ngokuthi yi-throuting pied. Ingajikelezwa ekuhleleni okuphelele ukufeza ingcindezi eyinhloko. Ngaphansi kwengcindezi, ukuthambekela kwangaphakathi kuyaphuma, okungagcini nje ngokuba nomthelela olungiselelwe ngokwako, kepha futhi kungena emgodini we-anchor lapho ichichima i-slurry, idlala indima ekuhlanganiseni idwala eliseduze. Inezinzuzo zayo ekusetshenzisweni nasekuhlelweni, ngakho-ke ingakhombisa izinzuzo zayo ekusetshenzisweni:
1, yingaphansi kwalomphumela ukuthi umphumela wokusekelwa okusheshayo we-Rapid ngokushesha ungatholakala futhi ukuguqulwa kwedwala elizungezile kungalawulwa kahle ukuthi umphumela wokuqina wokuqina ungatholakala.
2, isebenzisa indlela eyize ekuhleleni, ehlanganisa izinduku ze-anchor kanye namapayipi endlala. Yilolu hlobo lokuhlela olunezinzuzo ezinhle kakhulu. Uma kuyipayipi lendabuko lendabuko, kungadala ukulahleka ngenxa yokudonswa emuva nasekudonseni, okungeke kube khona into enjalo.
I-3, ingathuthukisa kakhulu ikhwalithi yephrojekthi, okuyinto ngokunembile ngoba ingafinyelela izinga elikhulu lokugcwala ngesikhathi sokulahla, futhi kanye ne-grouting, kungafinyelela umphumela wokucindezela kwengcindezi.
4 Ukungathathi hlangothi kwalo kuhle. Ngokungezwa kwezinye izesekeli ngesikhathi sokusetshenziswa, kukhulisa ukungathathi hlangothi kwayo, okuvumela ama-slurry asonge yonke ihange le-anchor eliyize. Kuyinto ngokunembile ngenxa yalokhu ukugqwala ngeke kubonakale ngesikhathi sokusebenzisa futhi kungakwazi ukukuthola ngempela ukusetshenziswa kwesikhathi eside.
5, futhi kulula kakhulu kudivayisi, okubaluleke kakhulu. Uma nje kulula kudivayisi, kunganciphisa isikhathi sokulungisa iphutha nezokwakha. Ngokubambisana nedivayisi, azikho ezinye izikulufa ezidingekayo ukuze zihlangabezane nezidingo ze-nati ne-pad.
