Thaum ua ntej, tusNtsia Hlau NtausFeem ntau yog siv los ua kom nruj cov paib khawm thiab cov phaj ib qho rau cov ntoo pw tsaug zog. Nrog kev tsim kho thiab kev txhim kho ntawm cov qhob footers, cov ntsia hlau spikes ua lub luag haujlwm tseem ceeb hauv kev tsheb ciav hlau fastening nrog kev pab los ntawm cov yas dowel. Txhawm rau kom tau raws li kev siv sib txawv thiab cov qauv ntawm cov ciav hlau sib txawv, cov ntsia hlau spikes tuaj yeem faib rau ntau hom. Tam sim no txhua txoj kev tsheb ciav hlau txawv yog ua tawm ntawm cov hlau ua hlau. Los ntawm cov kev cai sib txawv tshwj xeeb xws li qhov ntev, diametway, heexaging screat hlau loj thiab ob npaug {{4} he}} Lub taub hau ntsia hlau ntsia hlau loj.
4.6 qib SS See feefer ntsia hlau Spike yog tus ciav hlau ceev ceev siv los rau ntoo lossis cov neeg pw ua ke. Ua los ntawm 35 # Pa roj carbon hlau, nws muaj cov zog zoo thiab kev tiv thaiv kom tiv thaiv kev tawm ntawm cov haujlwm kev qhia.
