Posachedwa, kr90a romotary rig yobowoleza maziko a tyhen adapanga maziko olimbikitsa a Luyang, dera la Henan. Amanenedwa kuti geology imabweza miyala ndi silt, malo osungiramo maziko adzayambitsa ming'alu ndikusokoneza chitetezo cha zojambulazo. Njira yomwe ili pamalo ogwiritsira ntchito yoyambirira imaphatikizapo zolipirira zoyambira ndi mipata yobwerera, kenako ndikugwiritsa ntchito mulu wobowola kuti apange chithandizo cha maziko a malo olimbikitsira.
Mavuto a ntchitoyi ndi awa:
1. Ntchito yomanga mu fakitale yokhala ndi malire 12 m, malo omanga ndi ochepa, mabowo 600mm ndi kubowola 20 ~ 25m.
.
3. Kuti athane ndi mavutowa, mainjiniya ochokera ku Tyhen maziko adakonza njira yaukadaulo. Adasankha ogwiritsa ntchito aluso ndikusinthasintha rig ya kr90a yobowola yobowola, pogwiritsa ntchito mitu yotsika pansi ndi mitu yozungulira ndi mitu yobowola. Njirayi idawalola kuti aziwongolera zovuta za Rig ndikugwiritsa ntchito mawonekedwe ake obiriwira, kuzimitsa bwino strata yobwezeretsa. Zotsatira zake, ndalama zomangamanga zidachepetsedwa kuti kasitomalayo, apeze matamando osagwirizana ndi omwe akukhudzidwa ndi polojekiti.
Tysim kr90a coratala yobowola imakhala ndi injini ya 86kw, imalemera matani 25, ndipo imatha kumeta matonje ndi mainchesi mpaka 1200mm, ndi kuya kwakukulu kwa mita 28. Rig idapangidwa ndi zomanga zopepuka, zomwe zimapangitsa kuti kumwa kwambiri ndi injini chifukwa cha kuchepa kwake. Pansi pazinthu zofananira, mphamvu zambiri za injini zimaperekedwa kuti zigule. Kuphatikiza apo, ndodo zobowola zomwe zimagwiritsidwa ntchito ndi zopepuka, zimalola kuthamanga kwamphamvu ndikutsika kwa 75m / min pansi pazinthu zomwezi. Kuthamanga kwa Rig kumatha kufikira 5r / min, ndipo mutu wamphamvu umatha kuzungulira mwachangu pa 8-30r / min. Kupanga izi kumawonetsetsa kuti nthaka ikhale ilentation, mafuta ochepa mafuta, komanso luso la kapangidwe kake.
