Ventilation Technology Yomanga Tunnel Yapamwamba Kwambiri (Iti ipitilize)

3. Njira zopangira zopangira mpweya wabwino pamagawo osiyanasiyana omanga

3.1 Mfundo Zomangamanga Kapangidwe ka mpweya wabwino
3.1.1 Malinga ndi mpweya wabwino komanso ukhondo womanga ngalande m'madera okwera, ndikuganiziranso kuwongolera kwa mpweya wolemera mu mapiri, miyezo ya mpweya ndi mphamvu ya zida za nkhope ya ngalandeyo zimatsimikiziridwa.
3.1.2 Malingana ndi kukula kwa gawo la shaft yokhotakhota ndi zosowa za mpweya wautali wautali, kutalika kwa ma ducts olowera pansi pamtunda ndi 1500mm ~ 1800mm.
3.1.3 Kuti mukwaniritse kupulumutsa mphamvu kwabwino komanso zotsatira zabwino, yesani kugwiritsa ntchito liwiro la bipolar regulating axial flow fan. Pamene mpweya wofunikira umakhala waukulu, fani imathamanga kwambiri; pamene voliyumu yofunikira ya mpweya imakhala yochepa, fan imatha kuthamanga pa liwiro lotsika.

3.2 Kumanga shaft ndi njira ziwiri zogwirira ntchito zopangira mpweya wabwino

Panthawiyi, makina osindikizira amtundu umodzi amagwiritsidwa ntchito, monga momwe tawonetsera pa Chithunzi 1. M'dongosolo, nkhope iliyonse yogwira ntchito imagwiritsa ntchito kupanikizika mu mpweya wabwino mpaka kudutsa, aliyense wokonda kutsinde amathandizira 2 kumanga nkhope yogwira ntchito, nkhope iliyonse yogwira ntchito imatenga 1 pansi pa nthaka ventialtion duct, 1 kapena kuposa mafani mu mndandanda kapena ayi mndandanda, malinga ndi momwe mpweya weniweniwo umakhalira, zofuna za mphepo.

3.3 Kafukufuku wa Ventilation Scheme ya Multi-face Construction

3.3.1 Dongosolo la mpweya wabwino wa mafani awiri ndi ma tchanelo awiri komanso kupanikizika kwa nkhope iliyonse yogwira ntchito.

Pomanga ngalandeyo yayitali yokhala ndi ngalande zambiri zothandizira, ndizofala kukumba nkhope zingapo zogwirira ntchito nthawi imodzi. Muchiwembu ichi, mafani awiri amayikidwa pansi pa shaft yokhotakhota kuti akanikizire mpweya wodetsedwa ndi ngalande ziwiri, ndipo mpweya wabwino umalowa mumsewu kuchokera mumsewu wokhotakhota wa shaft, kenako ndikukankhira pankhope iliyonse yogwira ntchito kuchokera kwa fani yakomweko. Onani Chithunzi 2.

3.3.2 Dongosolo la mpweya wosakanikirana wa shaft bulkhead roadway

Pakufufuza kwa chiwembu cha mpweya wabwino, kuphatikiza kapangidwe kamene kamayendera kutsinde, tsinde lalitali limagawika kumtunda ndi kumunsi kwa gawo la mtanda (kutalika × m'lifupi 5.2mx 6.6m, gawo la mtanda ndi 31.4m²), utali wamtunda wa 2.6m semicircle, monga njira yolowera mpweya watsopano, mafani 4 amaikidwa pamzere wa pansi pa shaft yokhotakhota ndi dzenje lalikulu. Dongosolo la mpweya wabwino limapangidwa ndi njira zopangira mpweya kuti zipereke mpweya ku nkhope 4 zogwira ntchito za mzere Woyamba ndi Mzere II motsatana. Mpweya wobwerera m'mbuyo umatulutsidwa kunja kwa dzenje kudzera munjira yamakona anayi pansi pa shaft yokhazikika (m'lifupi x kutalika 6.6mx 3.34m)

Chithunzi 3 ndi chithunzi cholekanitsa cha shaft yokhazikika. Gulu lolekanitsa limapangidwa ndi bolodi la PVC ndikusindikizidwa ndi guluu; kugwirizana pakati pa bolodi lolekanitsa ndi khoma lakumbali la shaft yokhotakhota kumasindikizidwa ndi kusakaniza 107 guluu ndi putty ufa kapena galasi guluu.

Pulogalamuyi ili ndi zotsatirazi:

1. Pambuyo pa kupatukana kwa mpweya wa mpweya, kuchuluka kwa mpweya kumawonjezeka mwachiwonekere. Pambuyo kulekana kwa njira ya mpweya, njira imodzi yokhotakhota yokhotakhota imatha kukwaniritsa zosowa za nkhope za 3 zogwira ntchito nthawi imodzi, ndipo tsinde lamtundu wapawiri limatha kukwaniritsa zofunikira za nkhope za 4 zomwe zimagwira ntchito nthawi imodzi, zomwe zimapereka chitsimikizo cha mpweya wokwanira kuti mufulumizitse ntchito yomanga ngalande ya guan Jiao. Onani Chithunzi 4.

2. Dongosolo la mpweya wabwino ndi losavuta ndipo likhoza kugawidwa m'zigawo ziwiri zogwirira ntchito: kumanga shaft ndi kumanga dzenje lalikulu. Zinthu zina zitha kukhala zosavuta pamaziko a chiwembuchi.

3. Imawonetsetsa kuti mpweya wonse womwe umaperekedwa kumaso ndi mpweya wabwino, pomwe kuipa kwa njira zina zopumira mpweya kumakakamira mu mpweya wosungunuka woipitsidwa ndi utsi wagalimoto panthawi yoyendetsa kwambiri.

Choncho, ankakonda kutsinde mbale mpweya chitoliro mpweya mpweya amatengera mu No.5, No.6, No.8, No.9 ndi No.10 ankakonda kutsinde ntchito m'dera, ndi ngalande mpweya mpweya ngalande anatengera mu mipata ena.
