Chiyambi cha Zamalonda
Kuyika kwa chipangizo:
Safe Tunneling Technology mu Heterogeneous Ground
Mkhalidwe wa Geological:
Dothi lofewa, mawonekedwe osiyanasiyana (mchenga, miyala, kutsika kwambiri komanso kuthamanga kwamadzi)
The NPD mndandanda chitoliro jacking makina makamaka oyenera mikhalidwe geological ndi kuthamanga kwa madzi pansi ndi mkulu permeability coefficient nthaka. Slag yofukulidwa imatulutsidwa mumsewu ngati matope kudzera pampope yamatope, kotero imakhala ndi makhalidwe abwino kwambiri ogwira ntchito komanso malo ogwirira ntchito.
Malingana ndi njira zosiyanasiyana zoyendetsera matope pamtunda wofukula, makina a NPD omwe amawombera chitoliro akhoza kugawidwa m'mitundu iwiri: mtundu wowongolera mwachindunji ndi mtundu wamtundu wamtundu wamtundu (mtundu wowongolera mpweya wamagulu).
a. Makina owongolera amtundu wa chitoliro chowongolera amatha kuwongolera kuthamanga kwa tanki lamadzi lamatope posintha liwiro la pampu yamatope kapena kusintha kutsegulira kwa valavu yowongolera madzi amatope. Njira yowongolera iyi ndi yosavuta komanso yabwino, ndipo kulephera kwake kumakhala kochepa.
b. Makina osalunjika a chitoliro chojambulira mosadukiza amasintha kuthamanga kwa thanki yamadzi yamatope posintha kukakamiza kwa thanki ya mpweya. Njira yowongolera iyi imakhala ndi kuyankha kovutirapo komanso kulondola kwambiri.
1. The automatic control air cushion ikhoza kupereka chithandizo cholondola cha nkhope ya ngalandeyo, kuti zitsimikizire chitetezo cha kuyendetsa bwino kwambiri.
2. Tunneling itha kuchitidwanso ngati kuthamanga kwa madzi kuli pamwamba pa 15bar.
3. Gwiritsani ntchito matope ngati njira yaikulu kuti mugwirizane ndi kupanikizika kwa mapangidwe pamtunda wofukula wa ngalandeyo, ndikutulutsa slag kupyolera mumayendedwe oyendetsa matope.
4. NPD mndandanda chitoliro jacking makina ndi oyenera kumanga ngalande ndi kuthamanga kwa madzi ndi mkulu nthaka kukhazikika zofunika.
5. Kuyendetsa bwino kwambiri, kotetezeka komanso kodalirika, ndi njira ziwiri zoyendetsera kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.
6. The NPD mndandanda chitoliro jacking makina ndi zapamwamba ndi odalirika wodula mutu kapangidwe ndi kufalitsidwa matope.
7. The NPD mndandanda chitoliro jacking makina kutengera yodalirika kubala, chachikulu pagalimoto chisindikizo ndi main drive reducer, ndi moyo wautali utumiki ndi mkulu chitetezo factor.
8. Dongosolo la pulogalamu yodzipangira yokha, magwiridwe antchito a makina onse ndi otetezeka komanso odalirika, ndipo ntchitoyo ndi yabwino.
9. Nthaka yochuluka yogwira ntchito zosiyanasiyana, monga dothi lofewa, dongo, mchenga, miyala ya miyala, nthaka yolimba, yobwerera kumbuyo, ndi zina zotero.
10. Jekeseni wamadzi wodziyimira pawokha, dongosolo lotulutsa.
11. Liwiro lothamanga kwambiri ndi pafupifupi 200mm pamphindi.
12. Kumanga mwatsatanetsatane mkulu, chiwongolero mwina mmwamba, pansi, kumanzere ndi kumanja, ndi kwambiri chiwongolero ngodya madigiri 5.5.
13. Gwiritsani ntchito dongosolo lapakati lolamulira pansi, lotetezeka, mwachilengedwe, komanso losavuta.
14. Mndandanda wa mayankho opangidwa mwaluso angaperekedwe pazofunikira zosiyanasiyana za polojekiti.
