Njira yozungulira yobowola granite ndi miyala ina yolimba

Makhalidwe a miyala yolimba monga granite ndi chiopsezo cha kupangika kwa mabowo. Popanga maziko a milu ya milatho ikuluikulu yambiri, miluyo imafunika kulowa mumwala wolimba wosweka mpaka kuzama kwina, ndipo kukula kwa miluyo yopangidwira maziko a miluyi nthawi zambiri kumakhala pamwamba pa 1.5mm. Ngakhale mpaka 2m. Kuboola milu yolimba yoteroyo kumaika zofunikira kwambiri pa mphamvu ndi kupanikizika kwa zida, nthawi zambiri kumafuna mphamvu yoposa 280kN.m. Poboola mu mtundu uwu wa mapangidwe, kutayika kwa mano oboola kumakhala kwakukulu kwambiri, ndipo zofunikira zapamwamba zimayikidwa pa kukana kugwedezeka kwa zida.

Njira yomangira yobowola mozungulira imagwiritsidwa ntchito m'miyala yolimba monga granite ndi miyala yamchenga. Njira zotsatirazi ziyenera kutengedwa kuti ziwongolere bwino kupanga mabowo ndikuchepetsa zoopsa.

(1) Zipangizo zokhala ndi mphamvu ya 280kN.m kapena kupitirira apo ziyenera kusankhidwa kuti zigwiritsidwe ntchito pobowola. Konzani mano obowola omwe ali ndi kuuma kwambiri komanso magwiridwe antchito abwino opera pasadakhale. Madzi ayenera kuwonjezeredwa ku mapangidwe a anhydrous kuti achepetse kuwonongeka kwa mano obowola.

(2) Konzani bwino zida zobowolera. Mukabowola mabowo a milu yayikulu m'njira yotereyi, njira yobowolera yosankhidwa iyenera kusankhidwa. Mu gawo loyamba, chobowolera cha migolo chotalika chokhala ndi mainchesi a 600mm ~ 800mm chiyenera kusankhidwa kuti chichotse mwachindunji pakati ndikupanga nkhope yomasuka; kapena chobowolera chaching'ono cha mainchesi chiyenera kusankhidwa kuti chibowole kuti chipange nkhope yomasuka.

(3) Mabowo opendekeka akapezeka m'matanthwe olimba, zimakhala zovuta kwambiri kusesa mabowo. Chifukwa chake, mukakumana ndi malo opendekeka, ayenera kukonzedwa musanaboole bwino.
