3. Alternative kuvaka ventilation zvirongwa zvezvikamu zvakasiyana zvekuvaka
3.1 Nheyo dzeKuvaka Ventilation Dhizaini
3.1.1 Maererano neventilation uye hutsanana mitemo yekuvaka tunnel munzvimbo dzakakwirira-yakakwirira, uye tichifunga nezvekugadzirisa coefficient yehuremu hwemhepo mubani, maitiro ekupa mhepo uye simba remichina yechiso chemugero inotarwa.
3.1.2 Zvinoenderana nehukuru hwechikamu cheiyo shaft yakatemerwa uye kureba-kure kwemhepo kunoda, iyo dhayamita yepasi pevhu yemhepo ducts muyakarerekera shaft ndeye 1500mm ~ 1800mm.
3.1.3 Kuti uwane simba rekuchengetedza zviri nani uye kushanda zvakanaka, edza kushandisa bipolar speed regulating axial flow fan. Kana iyo mhepo inodiwa yakakura, fan inomhanya nekumhanya kukuru; kana vhoriyamu yemhepo inodiwa yakadzikira, fan inogona kumhanya nekumhanya kwakaderera.
3.2 Isai shaft kuvaka uye 2 yekushanda kumeso kwekuvaka mhepo chirongwa
Panguva ino, imwe-head press-in ventilation inoshandiswa, sezvinoratidzwa mumufananidzo 1. Muchigadziro, chiso chega chega chekushanda chinotora kumanikidzwa mukati memhepo yemhepo kusvika kuburikidza, imwe neimwe yakarerekera shaft inotsigira 2 kushanda chiso chekugadzirisa, chiso chimwe nechimwe chekushanda chinotora 1 pasi pevhu ventialtion duct, 1 kana kupfuura mafeni mumutsara kana kwete munhevedzano, maererano nemhepo chaiyo yemhepo, simba remhepo rinodiwa.
3.3 Tsvagiridzo paVentilation Scheme yeMulti-face Kuvaka
3.3.1 Ventilation scheme ye-double-fan uye kaviri-channel exhaust uye kumanikidza-mukati kwechiso chega chega chinoshanda.
Mukuvaka kwekuwedzera-refu tunnel ine akawanda ebetsero tunnels, zvakajairika kuchera zviso zvekushanda zvakawanda panguva imwe chete. Muchirongwa ichi, mafeni maviri anogadzikwa pazasi peshaft yakarerekera kudzvanya mweya yakasviba nematanho maviri, uye mweya mutsva unopinda mumugero uchibva kune yakatemerwa shaft nzira, wobva wadzvanya mune yega yega inoshanda kubva kune yemuno fan. Ona Mufananidzo 2.
3.3.2 Mixed ventilation scheme ye inclined shaft bulkhead roadway
Muchidzidzo chechirongwa chekufefetera, chakasanganiswa neyakarerekera shaft clearance dhizaini, iyo refu yakarerekera shaft yakakamurwa kuita epamusoro uye ezasi zvikamu zvechikamu chemuchinjikwa (urefu x hupamhi 5.2mx 6.6m, nzvimbo yemuchinjikwa ye31.4m2), radius yepamusoro ye 2.6m semicircle, semhepo itsva yekupinda mugero, 4 mafeni anoiswa pamharadzano yepasi peyakarerekera shaft uye gomba guru. Iyo yakamanikidzwa kufefetera system inoumbwa ine tunnel ventilation ducts kuti ipe mweya kune 4 kushanda zviso zvemutsara I uye Line II zvakateerana. Mhepo yekudzokera kumashure inoburitswa kunze kwegomba kuburikidza nenzira ine rectangular pazasi peyakarerekera shaft (hupamhi x kureba 6.6mx 3.34m)
Mufananidzo 3 ndiyo dhiyabhorosi yekuparadzanisa shaft yakarerekera. Bhodhi rekuparadzanisa rakagadzirwa nePVC board uye rakanamwa neglue; kuwirirana pakati pebhodhi rekuparadzanisa uye rusvingo rwemativi evhavha yakarerekera yakavharwa nemusanganiswa we107 glue uye putty powder kana girazi glue.
Iyo purogiramu ine zvinotevera zvakanakira:
1. Mushure mekuparadzaniswa kwemhepo yemhepo, huwandu hwemhepo hunowedzera pachena. Mushure mekuparadzaniswa kwemhepo duct, iyo imwe-lane yakarerekera shaft inogona kusangana nezvinodiwa zve3 kushanda zviso panguva imwe chete, uye kaviri-lane yakarerekera shaft inogona kusangana nezvinodiwa zve4 kushanda zviso panguva imwe chete, iyo inopa inodiwa yekufemesa vimbiso yekumhanyisa kuvakwa kweguan Jiao tunnel. Ona Mufananidzo 4.
2. Chirongwa chekufemesa chiri nyore uye chinogona kukamurwa kuita maviri mamiriro ekushanda: shaft kuvaka uye gomba guru rekuvaka. Mamwe mamiriro anogona kurerutswa pahwaro hwechirongwa ichi.
3. Inovimbisa kuti mhepo yose inopiwa kumeso imhepo yakachena, nepo kusakanganiswa kwemamwe magadzirirwo emhepo ari kumanikidzira mumhepo yakasvibiswa yakasvibiswa nemotokari yemotokari panguva yekufambisa kwepamusoro.
Naizvozvo, yakarerekera shaft ndiro air flue ventilation inogamuchirwa muNo.5, No.
