Zida zopangira phula zosakaniza phula zimatha kupanga kusakaniza kwa phula, kusakaniza kwa phula, ndi kusakaniza kwa phula, komwe kumakwaniritsa zofunikira zomanga misewu yayikulu, misewu yayikulu, misewu yamatauni, ma eyapoti, madoko, ndi zina zambiri. kulondola, zinthu zabwino zomalizidwa, komanso kuwongolera kosavuta, kumalandiridwa kwambiri pama projekiti amiyala ya phula, makamaka mapulojekiti amisewu yayikulu, koma nthawi zina kupatuka kumachitika panthawi yantchito, ndiye tiyenera kuchita chiyani izi zikachitika?

Kwa chosakanizira cha asphalt cha chinsalu chogwedezeka: thamangani ulendo umodzi popanda katundu, ndikuyambiranso ulendowo. Pambuyo pochotsa chingwe chatsopano cha matenthedwe, cholakwikacho chidakalipo. Yang'anani kukhudzana, kukana kwa injini, kukana kwapansi ndi magetsi, ndi zina zotero, ndipo palibe mavuto omwe anapezeka; tsitsani lamba wopatsira, yambitsani chinsalu chogwedezeka, ammeter ikuwonetsa zachilendo, ndipo palibe vuto ndikudumpha kwa mphindi 30 popanda kunyamula katundu. Cholakwika sichili mu gawo lamagetsi. Pambuyo pokonzanso lamba wotumizira, chinsalu chogwedezeka chinapezeka kuti chagonjetsedwa kwambiri ndi chipika cha eccentric.
Chotsani chipika cha eccentric, yambani chinsalu chogwedezeka, ammeter akuwonetsa zaka 15; mita ya maginito imayikidwa pa mbale ya bokosi logwedezeka, kuthamanga kwa radial kumafufuzidwa polemba tsinde, ndipo kutulutsa kwakukulu kwa radial ndi 3.5 mm; ovality pazipita wa kubala m'mimba mwake ndi 0,32 mm. Bwezerani chithunzithunzi chogwedezeka, ikani chipika cha eccentric, yambitsaninso chinsalu chogwedeza, ndipo ammeter imasonyeza bwino. Palibenso maulendo.
