Sisanda kunikezela nge-inthanethi yeselula enesivinini esikhulu kanye nokuxhumana kweselula ezindaweni ezingaphezulu zemithambeka ye-Elbrus ski. Manje isignali lapho ifinyelela ukuphakama kwamamitha angu-5100. Futhi lokhu kwakungeyona ukufakwa okulula kwemishini - ukufakwa kwenzeka ezinyangeni ezimbili ezimweni ezinzima zezulu. Ake sikutshele ukuthi kwenzeka kanjani.
Ukujwayela abakhi
Kwakubalulekile ukuvumelanisa abakhi nezimo eziphakeme zezintaba. Abafake izicelo bafike sekusele izinsuku ezimbili kuqale umsebenzi. Ukuhlala ubusuku obubili kwelinye lamaqhugwana akhuphuka izintaba akuzange kuveze noma yikuphi ukuthambekela kokugula kwasezintabeni (isicanucanu, isiyezi, ukuphelelwa umoya). Ngosuku lwesibili, abafakeli baqala umsebenzi omncane wokulungisa indawo. Kabili kwaba khona amakhefu ezobuchwepheshe athatha izinsuku ezingu-3-5 lilinye, lapho abakhi behlela ethafeni. Ukuzijwayeza okuphindaphindiwe kwaba lula futhi kushesha (usuku belwanele). Yiqiniso, ukushintsha kwesimo sezulu kungazelelwe kwanquma izimo zabo. Isibonelo, kwakudingeka sithenge izifudumezi ezengeziwe zokuzishisisa ukuze siqinisekise izimo zokusebenza ezivamile zabafaki.
Ukukhetha isayithi
Esigabeni sokukhetha isiza sokwakhiwa kwesiteshi esiyisisekelo, kwakudingeka siqale sicabangele izimo ezithile zezulu ezihlala ezindaweni eziphakeme. Okokuqala, indawo kufanele ifakwe umoya. Ngesikhathi esifanayo, amadiphozi eqhwa abheke emoyeni kanye neleeward akumele adalwe avimba ukufinyelela kusayithi. Ukufeza lezi zimo, kubalulekile ukukhomba isiqondiso somoya okhona, lapho ukugeleza komoya kuvame ukufika endaweni enikeziwe + amandla ayo.
Ukubhekwa kwesikhathi eside kwesimo sezulu kunikeze lawa manani aphakathi nendawo (%). Isiqondiso esivelele sigqanyiswe ngokubomvu.
Ngenxa yalokho, sakwazi ukuthola unqenqema oluncane olungafinyelelwa ngaphandle kobunzima obuningi phakathi nenkathi yeqhwa. Ukuphakama kwawo kungamamitha angama-3888 ngaphezu kwezinga lolwandle.
Ukufakwa kwemishini ye-BS
Ukuphakanyiswa kwezinto zokwakha kanye nemishini kwenziwa kuma-snowcats, njengoba imishini enamasondo yayingenamsebenzi ngenxa yokuqala kokuwa kweqhwa. Phakathi namahora asemini, ikati eqhweni lakwazi ukuphakama izikhathi ezingaphezu kwezimbili.
Imishini emincane yalethwa ngemoto yekhebula. Umsebenzi waqala ekuseni. Kungenzeka ukubikezela isimo sezulu emthambekeni we-Elbrus, kodwa ngesilinganiso esincane samathuba. Esimweni sezulu esicwebezelayo, kungase kubonakale ifu phezu kweziqongo (njengoba besho, u-Elbrus wafaka isigqoko sakhe). Khona-ke ingancibilika, noma ngehora iphenduke inkungu, iqhwa, noma umoya. Lapho isimo sezulu siba sibi, kubalulekile ukumboza amathuluzi nezinto zokwakha kusenesikhathi ukuze ungamba kamuva.
Lapho kuklanywa, “isiza” saphakanyiswa ngaphezu komhlabathi cishe ngamamitha amathathu ngokuthululelwa enhlabathini. Lokhu kwenzelwa ukuthi indawo ingambozwa iqhwa futhi asikho isidingo sokuyigingqa njalo ngama-snowcats.
Umsebenzi wesibili kwakuwukuvikela ngokuphepha isakhiwo "sesayithi", njengoba isivinini somoya ekuphakameni kwesiteshi sesisekelo sifinyelela ku-140-160 km / h. Kucatshangelwa isikhungo esiphezulu se-mass, ukuphakama kwesakhiwo kanye ne-windage yayo, kwanqunywa ukuthi singagcini ngokufaka i-concreting yamapayipi emgodini. Ngaphezu kwalokho, lapho simba inhlabathi yokufaka izisekelo, sahlangana namadwala aqine kakhulu, ngakho sakwazi ukujula imitha kuphela (ngaphansi kwezimo ezijwayelekile, ukujula kwenzeka ngaphezu kwamamitha amabili). Kwakudingeka futhi sifake izisindo zohlobo lwe-gabion (i-mesh enamatshe - bheka isithombe sokuqala).
Imingcele yokuklama yesiteshi sesisekelo ku-Elbrus yaphenduka okulandelayo: ububanzi besisekelo - 2,5 * 2,5 amamitha (ngokusekelwe kubukhulu bekhabhinethi yokushisa lapho imishini kufanele ifakwe). Ukuphakama - 9 m. Bawuphakamisele phezulu kangangokuthi isiteshi sizongena umoya futhi singambozwa yiqhwa. Ukuze uqhathanise, iziteshi eziyisicaba aziphakanyiselwa phezulu kangako.
Umsebenzi wesithathu kwakuwukuqinisekisa ukuqina kwesakhiwo okwanele okudingekayo ekusebenzeni okuzinzile kwemishini yokudlulisa umsakazo emoyeni onamandla. Ukuze kuzuzwe lokhu, isakhiwo saqiniswa ngezinsimbi zekhebula.
Ukuqinisekisa ukuthi izimo ezishisayo zemishini kuye kwaba nzima kangako. Ngenxa yalokho, yonke imishini yesiteshi eyamukela futhi idlulise amasignali omsakazo yafakwa ebhokisini elikhethekile lokuvikela, eliqinisekisa ukusebenza okungaphazamiseki kwesiteshi kunoma yiziphi izimo zezulu. Iziqukathi ezinjalo ezibizwa nge-Arctic zenzelwe izimo ezinzima ze-Arctic - ukunyuka kwemithwalo yomoya kanye namazinga okushisa amabi. Ziyakwazi ukumelana namazinga okushisa aze afike ku--60 degrees ngomswakama ophezulu.
Ungakhohlwa ukuthi ngesikhathi sokusebenza imishini nayo iyashisa, ngakho-ke kwachithwa umzamo omkhulu ekuqinisekiseni izimo ezivamile zokushisa. Lapha kwakudingeka sicabangele izici ezilandelayo: ukunciphisa kakhulu ukucindezela komkhathi (520 - 550 mmHg) kuphazamisa kakhulu ukudluliswa kokushisa komoya. Ngaphezu kwalokho, ukuvuleka kwezobuchwepheshe ngokushesha kuba yiqhwa, futhi iqhwa lingena ekamelweni nganoma yisiphi igebe, ngakho-ke akunakwenzeka ukusebenzisa "ukupholisa kwamahhala" izinhlelo zokushintshanisa ukushisa.
Ngenxa yalokho, indawo yokufakelwa kwezindonga kanye nemodi yokusebenza yekhabhinethi yokushisa ikhethiwe ngokuhlola.
Kwadingeka futhi sixazulule inkinga nge-ground loop kanye nokuvikelwa kombani. Inkinga iyafana naleyo yozakwethu ezindaweni ezisenyakatho ku-permafrost. Kuphela lapha sasinamatshe angenalutho. Ukumelana ne-loop kuyashintshashintsha kancane kuye ngesimo sezulu, kodwa kuhlale kungama-oda angu-2-3 obukhulu ngaphezu kokuvunyelwe. Ngakho-ke, kwadingeka sidonse intambo yesihlanu kanye nogesi esiteshini sikagesi semoto yekhebula.
Ukucaciswa kwesiteshi okuyisisekelo
Ngokucabangela izifiso zoMnyango Wezimo Eziphuthumayo waseRussia, ngaphezu kwesiteshi sesisekelo se-3G, iphrojekthi ihlanganisa ukwakhiwa kwe-2G BS. Njengomphumela walokho, sithole ikhwalithi ephezulu ye-UMTS 2100 MHz kanye ne-GSM 900 MHz yawo wonke umthambeka oseningizimu we-Elbrus, okuhlanganisa umzila oyinhloko wokukhuphukela ejikeni (5416 m) lehhashi.
Njengomphumela womsebenzi, iziteshi ezimbili eziyisisekelo zohlobo olusabalalisiwe zafakwa "esizeni," esihlanganisa iyunithi yokucubungula imvamisa yesisekelo (BBU) kanye neyunithi yomsakazo oqhelile (RRU). I-interface ye-CPRI isetshenziswa phakathi kwe-RRU ne-BBU, inikeza uxhumano phakathi kwamamojula amabili usebenzisa izintambo ezibonakalayo.
I-GSM ejwayelekile - 900 MHz - DBS3900 ekhiqizwa i-Huawei (PRC).
I-WCDMA ejwayelekile - 2100 MHz - RBS 6601 eyenziwe ngabakwa-Ericsson (Sweden).
Amandla okudlulisa akhawulelwe kuma-Watts angama-20.
Isiteshi sesisekelo sinikwa amandla kusuka kumanethiwekhi kagesi ezimoto zekhebula - akukho okunye. Uma ugesi ucishiwe, abasebenzi abasebenzayo bacisha isiteshi sesisekelo se-3G futhi kusele umkhakha owodwa we-2G, ubheke ngase-Elbrus. Lokhu kusiza ukuthi uhlale uxhumene, okuhlanganisa nabatakuli. Amandla okulondoloza ahlala amahora angu-4-5. Ukunikeza ukufinyelela kwabasebenzi ezintweni zokulungisa akufanele kudale izinkinga ezithile lapho imoto yekhebula isebenza. Uma kunezimo eziphuthumayo kanye nokuphuthuma okwandisiwe, ukuphakamisa ngezimoto zeqhwa kunikezwa.
