Posachedwapa tapereka intaneti yothamanga kwambiri komanso mauthenga a m'manja kumadera akumtunda a Elbrus ski slopes. Tsopano chizindikiro kumeneko ukufika kutalika kwa 5100 mamita. Ndipo izi sizinali zosavuta kukhazikitsa zida - kukhazikitsa kunachitika kwa miyezi iwiri m'malo ovuta a nyengo yamapiri. Tiye tikuuzeni mmene zinachitikira.
Kusintha kwa omanga
Zinali zofunikira kusintha omangawo kuti agwirizane ndi mapiri aatali. Oyikirawo adafika masiku awiri ntchito isanayambe. Kukhala usiku kuΕ΅iri mβkanyumba kena kokwera mapiri sikunasonyeze chikhoterero chirichonse cha matenda a mβmapiri (mseru, chizungulire, kupuma movutikira). Patsiku lachiwiri, oyikapo adayamba ntchito yopepuka yokonzekera malowo. Kawiri panali zopumira zaukadaulo zomwe zimatha masiku 3-5 aliyense, pomwe omanga adatsikira pachigwa. Kusintha mobwerezabwereza kunali kosavuta komanso mofulumira (tsiku linali lokwanira). Nβzoona kuti kusintha kwadzidzidzi kwa nyengo kunachititsa kuti asinthe. Mwachitsanzo, tinkafunika kugula ma heater owonjezera odzitenthetsera kuti titsimikizire kuti okhazikitsa akugwira ntchito bwino.
Kusankha malo
Posankha malo oti amangepo siteshoni yapansi panthaka, choyamba tinayenera kuganizira za nyengo ya kumapiri. Choyamba, malowa ayenera kukhala ndi mpweya wabwino. Panthawi imodzimodziyo, ma deposits a snowward ndi leeward sayenera kupangidwa zomwe zimalepheretsa kupeza malo. Kuti mukwaniritse zikhalidwezi, ndikofunikira kuzindikira komwe mphepo ikupita, komwe mpweya umatuluka nthawi zambiri kudera lomwe mwapatsidwa + mphamvu zake.
Kuyang'ana kwanyengo kwanthawi yayitali kunapatsa mitundu iyi yamtunduwu (%). Kuwongolera kwakukulu kumawonetsedwa mofiira.
Chifukwa cha zimenezi, tinakwanitsa kupeza kanjira kakangβono kamene tingafikeko popanda vuto lililonse mβnyengo ya chipale chofewa kwambiri. Kutalika kwake ndi mamita 3888 pamwamba pa nyanja.
Kuyika zida za BS
Kukweza zida ndi zida kunkachitika pamiyala ya chipale chofewa, popeza zida zamawilo zinali zopanda ntchito chifukwa cha kugwa kwa chipale chofewa. Masana, chipale chofewacho sichinkakwera kupitirira kawiri.
Zida zing'onozing'ono zinaperekedwa ndi galimoto ya chingwe. Ntchito inayamba kutuluka kwa dzuwa. N'zotheka kulosera nyengo pa malo otsetsereka a Elbrus, koma ndi pang'ono digiri Mwina. M'nyengo yowala kwambiri, mtambo ungawoneke pamwamba pa nsonga (monga amanenera, Elbrus amavala chipewa chake). Kenako imatha kusungunuka, kapena mu ola limodzi kusanduka chifunga, matalala, kapena mphepo. Nyengo ikayamba kuipiraipira, ndikofunikira kuphimba zida ndi zida munthawi yake kuti musakumbidwe pambuyo pake.
Popanga, "malo" adakwezedwa pamwamba pa nthaka ndi pafupifupi mamita atatu pothira m'nthaka. Izi zinachitidwa kuti malowo asakutidwe ndi chipale chofewa komanso kuti pasakhale chifukwa cholipiritsa nthawi zonse ndi mapiri a chipale chofewa.
Ntchito yachiwiri inali yotetezera bwino dongosolo la "malo", popeza mphepo yamkuntho pamtunda wa siteshoni yoyambira imafika 140-160 km / h. Poganizira malo apamwamba a misa, kutalika kwa kapangidwe kake ndi mphepo yake, adaganiza kuti tisamangokhalira kupanga zitoliro mu dzenje. Komanso, pofukula nthaka kuti tiyike zothandizira, tinakumana ndi miyala yolimba kwambiri, kotero tinatha kupita mozama mita imodzi (muzochitika zabwino, kuzama kumachitika kupitirira mamita awiri). Tidayeneranso kukhazikitsa zolemera zamtundu wa gabion (ma mesh okhala ndi miyala - onani chithunzi choyamba).
Mapangidwe a malo oyambira pa Elbrus adakhala awa: m'lifupi mwake - 2,5 * 2,5 metres (kutengera kukula kwa kabati yotenthetsera momwe zida ziyenera kuyikidwira). Kutalika - 9 m. Analikweza pamwamba kwambiri kotero kuti siteshoniyo inkalandira mpweya wabwino komanso wosakutidwa ndi chipale chofewa. Poyerekeza, masiteshoni apansi apansi samakwezedwa mpaka kutalika kotere.
Ntchito yachitatu inali yotsimikizira kukhazikika kokwanira kofunikira kuti zida zotumizirana mawayilesi ziziyenda mokhazikika pamphepo zamphamvu. Kuti akwaniritse izi, dongosololi linalimbikitsidwa ndi zingwe za chingwe.
Kuonetsetsa kuti kutentha kwa zidazo kunali kovuta. Chotsatira chake, zipangizo zonse zamasiteshoni zomwe zimalandira ndi kutumiza mauthenga a wailesi zinayikidwa mu bokosi lapadera lotetezera, lomwe limatsimikizira kugwira ntchito kosasokonezeka kwa siteshoni pa nyengo iliyonse. Zotengera zotere zotchedwa Arctic zidapangidwa kuti zikhale zovuta za Arctic - kuchuluka kwa mphepo komanso kutentha koyipa. Amatha kupirira kutentha mpaka -60 madigiri ndi chinyezi chambiri.
Musaiwale kuti panthawi yogwiritsira ntchito zipangizozo zimawotcha, choncho kuyesetsa kwakukulu kunagwiritsidwa ntchito pofuna kuonetsetsa kuti kutentha kuli bwino. Apa tinayenera kuganizira zinthu zotsatirazi: kuchepetsa kwambiri mpweya wa mumlengalenga (520 - 550 mmHg) kumawononga kwambiri kutentha kwa mpweya. Kuphatikiza apo, kutseguka kwaukadaulo nthawi yomweyo kumaundana, ndipo chisanu chimalowa m'chipindacho kudzera mumpata uliwonse, kotero ndizosatheka kugwiritsa ntchito "kuzizira kwaulere" machitidwe osinthira kutentha.
Zotsatira zake, dera la insulation la makoma ndi njira yogwiritsira ntchito kabati yotenthetsera idasankhidwa moyesera.
Tinayeneranso kuthetsa vutoli ndi chitetezo chapansi ndi mphezi. Vuto ndilofanana ndi la ogwira nawo ntchito kumadera a kumpoto pa permafrost. Kumeneko kokha tinali ndi miyala yopanda kanthu. Kukaniza kwa loop kumasinthasintha pang'ono kutengera nyengo, koma nthawi zonse kumakhala 2-3 magnitude apamwamba kuposa ovomerezeka. Choncho, tinayenera kukoka waya wachisanu pamodzi ndi magetsi opita kumalo osungirako magetsi a galimoto ya chingwe.
Mafotokozedwe a Base station
Poganizira zofuna za Unduna wa Zadzidzidzi ku Russia, kuwonjezera pa malo oyambira a 3G, pulojekitiyi idaphatikizaponso kumanga 2G BS. Zotsatira zake, tidalandira mawonekedwe apamwamba kwambiri a UMTS 2100 MHz ndi GSM 900 MHz kutsetsereka konse kwakummwera kwa Elbrus, kuphatikiza njira yayikulu yokwerera popindika (mamita 5416) a chishalo.
Chifukwa cha ntchitoyi, masiteshoni awiri amtundu wogawidwa adayikidwa pa "malo," opangidwa ndi base frequency processing unit (BBU) ndi remote radio frequency unit (RRU). Mawonekedwe a CPRI amagwiritsidwa ntchito pakati pa RRU ndi BBU, kupereka kugwirizana pakati pa ma modules awiri pogwiritsa ntchito zingwe za kuwala.
GSM muyezo - 900 MHz - DBS3900 yopangidwa ndi Huawei (PRC).
WCDMA muyezo - 2100 MHz - RBS 6601 yopangidwa ndi Ericsson (Sweden).
Mphamvu ya transmitter imangokhala 20 Watts.
Malo oyambira amayendetsedwa kuchokera kumagetsi amagetsi a magalimoto a chingwe - palibe njira ina. Mphamvu yamagetsi ikazimitsidwa, ogwira ntchito amazimitsa malo oyambira a 3G ndipo gawo limodzi lokha la 2G limatsalira, kuyang'ana ku Elbrus. Izi zimathandiza kuti nthawi zonse muzilumikizana, kuphatikizapo opulumutsa. Mphamvu zosunga zobwezeretsera zimatha maola 4-5. Kupereka mwayi kwa ogwira ntchito kuti akonze zida sikuyenera kubweretsa vuto lililonse pomwe chingwe chagalimoto chikugwira ntchito. Pazifukwa zadzidzidzi komanso kuchuluka kwachangu, kukweza ndi ma snowmobile kumaperekedwa.
