Isu nguva pfupi yadarika takapa nharembozha inomhanya zvakanyanya uye nharembozha kumatunhu epamusoro eElbrus ski materu. Iye zvino chiratidzo ipapo chinosvika kureba kwemamita 5100. Uye iyi yakanga isiri nyore kugadzwa kwemidziyo - kuiswa kwakaitika kwemwedzi miviri mumamiriro ekunze akaoma emakomo. Ngatikuudzei kuti zvakaitika sei.
Kugadziriswa kwevanovaka
Zvakanga zvakakosha kugadzirisa vavaki kumamiriro emakomo akakwirira. Mainstallers akasvika mazuva maviri basa risati ratanga. Kugara kweusiku huviri muimwe yedzimba dzokukwira makomo hakuna kuratidza kombamiro ipi neipi yechirwere chegomo (kusvotwa, dzungu, kutadza kufema). Pazuva rechipiri, vagadziri vakatanga basa rakareruka kugadzirira nzvimbo yacho. Kaviri pakanga paine tekinoroji kutyora kwakatora mazuva 3-5 imwe neimwe, apo vavaki vakaburukira kubani. Kudzokororwa kugadzirisa kwaive nyore uye nekukurumidza (zuva raive rakakwana). Chokwadika, kuchinja kwakamwe kamwe kwemamiriro okunze kwakaraira mamiriro avo ezvinhu. Semuenzaniso, taifanira kutenga mamwe maheater ekudziisa kuti tive nemamiriro ekushanda akajairika kune vanoisa.
Sarudzo yesaiti
Padanho rekusarudza nzvimbo yekuvaka chiteshi chepasi, takatanga tafunga nezvemamiriro ekunze emamiriro ekunze enzvimbo dzakakwirira. Chokutanga pane zvose, nzvimbo yacho inofanira kufefeterwa. Panguva imwecheteyo, windward uye leeward snow deposits haifaniri kugadzirwa iyo inotadzisa kuwana nzvimbo. Kuti uzadzise mamiriro aya, zvakakosha kuziva kutungamira kwemhepo iripo, kubva iyo inoyerera mhepo inowanzouya kune imwe nzvimbo yakapihwa + simba rayo.
Kutarisa kwenguva refu kwemamiriro ekunze kwakapa aya avhareji mhepo yakasimuka kukosha (%). Iyo inotungamira kutungamira inojekeswa mutsvuku.
Somuuyo, takakwanisa kuwana rukova ruduku runogona kusvikwa pasina kuoma kukuru mukati menhambo yechando zvikurusa. Kureba kwayo 3888 metres pamusoro pegungwa.
Kuiswa kweBS michina
Kusimudzwa kwezvinhu nemidziyo yakaitwa pamakatsi echando, sezvo michina yemavhiri yakanga isingabatsiri nekuda kwekutanga kwechando. Mukati memasikati, makati echando akakwanisa kusimuka zvisingapfuuri kaviri.
Midziyo midiki yakaunzwa nemotokari yetambo. Basa rakatanga kubuda zuva. Zvinokwanisika kufanotaura mamiriro ekunze pamateru eElbrus, asi nediki diki diki. Mumamiriro okunze akajeka, gore rinogona kuoneka pamusoro penhongonya (sezvavanotaura, Elbrus akapfeka ngowani yake). Ipapo inogona kunyungudika, kana muawa imwe kushanduka kuita mhute, sinou, kana mhepo. Kana mamiriro okunze akashata, zvakakosha kuvhara zvishandiso uye zvinhu munguva kuitira kuti usazochera gare gare.
Pakugadzira, "saiti" yakasimudzwa pamusoro pevhu nemamita anenge matatu nekudurura muvhu. Izvi zvakaitwa kuitira kuti nzvimbo yacho isafukidzwe nesinou uye paisazova nechikonzero chekugara ichiumburudzwa nekatsi dzechando.
Basa rechipiri raive rekuchengetedza zvakachengeteka "saiti" chimiro, sezvo mhepo inomhanya pahupamhi hwebhesi station inosvika 140-160 km / h. Tichifunga nezve nzvimbo yakakwirira yehuremu, kureba kwechimiro uye mhepo yaro, zvakasarudzwa kuti tisazviisa pachedu pakugadzira pombi inomira mugomba. Uyezve, pakuchera ivhu rekuisa zvitsigiso, takasangana nematombo akaoma kwazvo, saka takakwanisa kudzika mita imwe chete (pasi pemamiriro ezvinhu akajairika, kudzika kunoitika kupfuura mamita maviri). Isu taifanira kuwedzera kuisa gabion-mhando uremu (mesh nematombo - ona wekutanga mufananidzo).
Iyo dhizaini paramita ye base station paElbrus yakave inotevera: base hupamhi - 2,5 * 2,5 metres (zvichienderana nehukuru hwekabati yekudziya umo michina yaifanira kuiswa). Kureba - 9 mamita. Vakaisimudza zvekuti chiteshi chacho chaibva chapinzwa mhepo uye chisingafukidzwi nechando. Kuenzanisa, zviteshi zvepasi pasi hazvina kusimudzwa kusvika pakukwirira kwakadaro.
Basa rechitatu raive rekuona kusimba kwechimiro chakakwana pakushanda kwakagadzikana kwemidziyo yeredhiyo mumhepo ine simba. Kuti izvi zviitike, chimiro chacho chakasimbiswa netambo dzetambo.
Kuve nechokwadi chekuti mamiriro ekupisa emidziyo akave asina kuoma. Nekuda kweizvozvo, ese midziyo yechiteshi inogamuchira uye inotumira masaini eredhiyo yakaiswa mubhokisi rakakosha rekudzivirira, iro rinoona kusakanganiswa kushanda kwechiteshi mune chero mamiriro ekunze. Izvi zvinodaidzwa kuti Arctic midziyo yakagadzirirwa mamiriro akaomarara eArctic - yakawedzera mitoro yemhepo uye tembiricha yakaipa. Vanokwanisa kumira tembiricha kusvika -60 madhigirii ane hunyoro hwepamusoro.
Usakanganwa kuti panguva yekushanda midziyo inopisawo, saka kuedza kwakawanda kwakashandiswa pakuona mamiriro ekupisa. Pano taifanira kufunga nezvezvinhu zvinotevera: kuderedzwa kwakanyanya kwemhepo yemhepo (520 - 550 mmHg) kunokanganisa zvakanyanya kupisa kwemhepo. Uye zvakare, iyo tekinoroji kuvhurika inokurumidza kutonhora, uye chando chinopinda mukamuri kuburikidza nechero gaka, saka hazvibviri kushandisa "yemahara kutonhora" kupisa kupisa masisitimu.
Nekuda kweizvozvo, nzvimbo yekudzivirira kwemadziro uye maitiro ekushandisa eiyo kabati yekudziya yakasarudzwa kuyedza.
Taifanirawo kugadzirisa nyaya yacho negrounding loop nekudzivirira mheni. Dambudziko rakafanana nerevamwe vaunoshanda navo munzvimbo dzekuchamhembe pane permafrost. Apa chete taiva nematombo asina chinhu. Iyo loop resistance inoshanduka zvishoma zvichienderana nemamiriro ekunze, asi inogara iri 2-3 maodha ehukuru hwepamusoro pane inotenderwa. Naizvozvo, taifanira kudhonza waya yechishanu pamwe chete nemagetsi kuchiteshi chemagetsi chemotokari yetambo.
Base station specifications
Tichifunga nezvezvishuwo zveRussia Ministry of Emergency Situations, kuwedzera kune 3G base station, chirongwa ichi chaisanganisira kuvakwa kwe2G BS. Nekuda kweizvozvo, takagamuchira yemhando yepamusoro UMTS 2100 MHz uye GSM 900 MHz kufukidzwa kweyese kutsetseka kwekumaodzanyemba kweElbrus, kusanganisira nzira huru yekukwira kubhenda (5416 m) yechigaro chechigaro.
Nekuda kwebasa, zviteshi zviviri zvakagoverwa-mhando yepasi yakaiswa pa "saiti," inosanganisira base frequency processing unit (BBU) uye kure radio frequency unit (RRU). Iyo CPRI interface inoshandiswa pakati peRRU neBBU, ichipa kubatana pakati pema modules maviri uchishandisa optical cables.
GSM chiyero - 900 MHz - DBS3900 yakagadzirwa neHuawei (PRC).
WCDMA chiyero - 2100 MHz - RBS 6601 yakagadzirwa na Ericsson (Sweden).
Transmitter simba rinogumira ku20 Watts.
Iyo base station inopihwa simba kubva kumagetsi network yetambo mota - hapana imwe nzira. Kana magetsi adzimwa, vashandi vanoshanda vanodzima 3G base station uye chikamu chimwe chete che2G chinosara, chakatarisa kuElbrus. Izvi zvinobatsira kugara uchibatana, kusanganisira nevanunuri. Simba rekuchengetedza rinogara kwemaawa 4-5. Kupa mukana kune vashandi kugadzirisa michina haifanire kuunza chero matambudziko kana mota yetambo iri kushanda. Muchiitiko chekukurumidzira uye kuwedzera kwekukurumidzira, kusimudzwa nemasnowmobiles kunopihwa.
