Mulu wa pansi wopindikandi mulu wobowola pansi wopangidwa ndi screw drill, womwe umadziwika kuti uli ndi drill bit ndi drill payipi, ndipo drill bit kapena drill payipi imalumikizidwa ndi cholumikizira chamagetsi; Muluwo ukangoyendetsedwa pansi pa nthaka, sudzachotsedwa ndipo udzagwiritsidwa ntchito mwachindunji ngati mulu.
Zidutswa zomwe zafotokozedwa pamwambapa zikuphatikizapo pansi pa auger bit
1, chitoliro chapakati chachitsulo
2, Upper polumikiza chitoliro
3, Chitoliro chobowola chimakhala ndi chitoliro cholumikizira chapamwamba
4, ndodo yachitsulo yapakati
5, kutsinde lolumikizira lotsika
6, Pambuyo poyendetsedwa pansi pa nthaka, muluwu suchotsedwanso, koma umagwiritsidwa ntchito mwachindunji ngati mulu.
Pogwiritsa ntchito kapangidwe ka "mulu wonyamula katundu" ndi kapangidwe ka "mulu wokangana" pomanga, imagwiritsidwa ntchito kwambiri popanga milu yosiyanasiyana ya nthaka, zomangira nthaka ndi milu ya nthaka yopangidwa mwachisawawa.
Ukadaulo wokonza mulu wozungulira pansi
Kawirikawiri, milu yoyenerera ya nthaka imatha kupangidwa kudzera mu kudula, kusintha mawonekedwe, kuwotcherera, kusakaniza, kuyika ma plating otentha ndi njira zina zaukadaulo. Kusakaniza ndi kuyika ma galvanizing otentha ndi njira zofunika kwambiri zothanirana ndi dzimbiri, zomwe zimakhudza mwachindunji moyo wa ntchito ya milu yozungulira ya nthaka.
Mlingo wogwiritsira ntchito mulu wa nthaka umatsimikizira mwachindunji moyo wa mulu wa nthaka wachitsulo, monga ubwino wa chitoliro cholumikizidwa, kuchuluka kwa ubwino wa kulumikiza, ngati pali mabowo amchenga, kulumikiza konyenga ndi m'lifupi wa kulumikiza, zomwe zonse zimakhudza moyo wamtsogolo wa mulu wa nthaka ndi ubwino wa kulumikiza pambuyo pake. Kusankha ndi njira yofunika kwambiri yolimbana ndi dzimbiri, ndipo ubwino wa kulumikiza kotentha, monga nthawi yolumikizira kutentha ndi ubwino wa kulumikiza pamwamba, Zonsezi zimakhudza ubwino wa kulumikiza kotentha. Kawirikawiri, mulu wa nthaka wozungulira ungagwiritsidwe ntchito kwa zaka 40-80. Malo ndi njira yogwiritsira ntchito njira yogwiritsira ntchito zimakhudzanso moyo wa kulumikiza mulu wa nthaka, monga mlingo wa acid-base wa nthaka, ngati njira yogwirira ntchito ndi yoyenera, ndipo kugwiritsa ntchito molakwika kudzatsogolera ku kuwonongeka kwa pamwamba pa mulu wa nthaka wachitsulo, kuwonongeka kwa wosanjikiza woteteza chitsulo, kufulumizitsa dzimbiri la mulu wa nthaka wachitsulo ndi kuchepetsa moyo wa ntchito.
Chidziwitso chogwiritsa ntchito mulu wozungulira
Mulu wozungulira pansinthawi zambiri amagwiritsidwa ntchito kulimbitsa mahema m'nthaka yamchenga ndikuletsa mahema kuti asawombedwe ndi mphepo. Nthawi yomweyo, mphamvu yosungira nthaka yaZitsulo Zokulungira Milundi bwino kuposa mulu wa nthaka wopendekeka womwe uli m'nthaka yofewa yamchenga
