Kutshanje sinikezele nge-Intanethi enesantya esiphezulu kunye nonxibelelwano oluphathwayo kumacandelo aphezulu e-Elbrus ski slopes. Ngoku umqondiso apho ufikelela kubude beemitha ezingama-5100. Kwaye oku kwakungekho lula ukufakwa kwezixhobo - ukufakwa kwenzeka kwiinyanga ezimbini kwiimeko ezinzima zemozulu. Makhe sikuxelele ukuba kwenzeka njani.
Ukulungelelanisa abakhi
Kwakubalulekile ukulungelelanisa abakhi kwiimeko zeentaba eziphakamileyo. Abafakeli bafika kwiintsuku ezimbini ngaphambi kokuqala komsebenzi. Ukuhlala ubusuku obubini kwelinye lamagumbi okunyuka intaba akuzange kubonise naluphi na utyekelo lokugula entabeni (isicaphucaphu, isiyezi, ukuphefumla nzima). Ngosuku lwesibini, abafakeli baqalisa umsebenzi olula wokulungisa isiza. Kabini kukho ikhefu lobuchwepheshe elithatha iintsuku ezi-3-5 nganye, xa abakhi behla ethafeni. Ukuziqhelanisa okuphindaphindiweyo kwaba lula kwaye ngokukhawuleza (usuku lwayanele). Kakade ke, iimeko zabo zatshintsha ngesiquphe imozulu. Umzekelo, kwafuneka sithenge izifudumezi ezongezelelweyo zokuzifudumeza ukuze siqinisekise iimeko eziqhelekileyo zokusebenza kubafaki.
Ukukhetha indawo
Kwinqanaba lokukhetha isiza sokwakhiwa kwesikhululo esisisiseko, kwafuneka kuqala sithathele ingqalelo iimeko ezithile zemozulu kwiindawo eziphakamileyo. Okokuqala, indawo kufuneka ifakwe umoya. Kwangaxeshanye, iidiphozithi zekhephu ze-windward kunye ne-leeward akufanele zidalwe ezithintela ukufikelela kwisiza. Ukuzalisekisa le miqathango, kubalulekile ukuchonga isalathiso somoya okhoyo, apho ukuhamba komoya kudla ngokufika kwindawo enikiweyo + amandla ayo.
Uphononongo lwexesha elide lwemozulu lunike la maxabiso aphakathi kwe-wind rose (%). Ulwalathiso oluphambili lugxininiswe ngobomvu.
Ngenxa yoko, sakwazi ukufumana ungqameko oluncinane olunokufikelelwa ngaphandle kobunzima obungako ebudeni belo xesha likhithikayo. Ubude bayo buziimitha ezingama-3888 ngaphezu komphakamo wolwandle.
Ukufakwa kwezixhobo zeBS
Ukuphakanyiswa kwezinto kunye nezixhobo zenziwa kwiikhephu zekhephu, kuba izixhobo ezinamavili zazingenamsebenzi ngenxa yokuqala kwekhephu. Ebudeni bemini, ikhephu lalingakwazi ukuphakama ngaphezu kwezihlandlo ezibini.
Izixhobo ezincinci zaziswa ngemoto yentambo. Umsebenzi wawuqala ukuphuma kwelanga. Kunokwenzeka ukuxela kwangaphambili imozulu kwithambeka le-Elbrus, kodwa ngeqondo elincinci lokunokwenzeka. Kwimozulu ecacileyo, ilifu linokuvela phezu kweencopho (njengoko besitsho, uElbrus wabeka umnqwazi wakhe). Emva koko inokunyibilika, okanye ngeyure ijike ibe yinkungu, ikhephu, okanye umoya. Xa imozulu imbi, kubalulekile ukugquma izixhobo kunye nezixhobo kwangethuba ukuze ungagrumbi kamva.
Xa kuyilwa, "indawo" yaphakanyiswa ngaphezu komhlaba malunga neemitha ezintathu ngokugalela emhlabeni. Oku kwenziwa ukuze indawo ingagqunywa likhephu kwaye kungabikho mfuneko yokuyiqengqeleka rhoqo ngeekhephu.
Umsebenzi wesibini wawukukhusela ngokukhuselekileyo isakhiwo "sesiza", ekubeni isantya somoya ekuphakameni kwesikhululo sesiseko sifikelela kwi-140-160 km / h. Ukuthathela ingqalelo iziko eliphakamileyo lobunzima, ukuphakama kwesakhiwo kunye ne-windage yayo, kwagqitywa ukuba singayikhawuleli kwi-concreting imibhobho yokumisa emhadini. Ngaphezu koko, xa umba umhlaba wokufaka izixhaso, sadibana namatye anzima kakhulu, ngoko sakwazi ukujula kuphela imitha (phantsi kweemeko eziqhelekileyo, ukujula kwenzeka ngaphezu kweemitha ezimbini). Kwafuneka sifake iintsimbi zohlobo lwe-gabion (i-mesh enamatye - bona ifoto yokuqala).
Iiparameters zoyilo lwesikhululo sesiseko kwi-Elbrus zajika zibe zilandelayo: ububanzi besiseko - 2,5 * 2,5 yeemitha (ngokusekelwe kubukhulu bekhabhinethi yokufudumala apho kufuneka kufakwe izixhobo). Ubude - 9 yeemitha. Bawuphakamisela phezulu kangangokuba esi sikhululo sasinokungena umoya ukuze singagqunywa likhephu. Ukuthelekisa, izikhululo ezisezantsi aziphakanyiselwanga kubude obunjalo.
Umsebenzi wesithathu yayikukuqinisekisa ukuqina okwaneleyo kwesakhiwo esiyimfuneko ekusebenzeni ngokuzinzileyo kwezixhobo zosasazo lukanomathotholo kwimimoya ebhudla ngamandla. Ukufezekisa oku, isakhiwo saqiniswa ngeentambo zentambo.
Ukuqinisekisa ukuba iimeko ezishushu zezixhobo zajika zaba nzima. Ngenxa yoko, zonke izixhobo zesikhululo ezifumana kunye nokuhambisa izibonakaliso zerediyo zifakwe kwibhokisi ekhethekileyo yokukhusela, eqinisekisa ukusebenza okungaphazamisekiyo kwesitishi kuyo nayiphi na imeko yemozulu. Izikhongozeli ezinjalo ezibizwa ngokuba yi-Arctic zenzelwe iimeko ezinzima zeArctic - ukunyuka kwemithwalo yomoya kunye namaqondo obushushu abi. Ziyakwazi ukumelana namaqondo obushushu ukuya kutsho kwi -60 degrees kunye nokufuma okuphezulu.
Ungalibali ukuba ngexesha lokusebenza izixhobo zifudumeza, ngoko ke umzamo omkhulu wachithwa ekuqinisekiseni iimeko eziqhelekileyo zokushisa. Apha kwafuneka sithathele ingqalelo ezi zinto zilandelayo: ukunciphisa kakhulu uxinzelelo lwe-atmospheric (520 - 550 mmHg) kuphazamisa kakhulu ukuhanjiswa kobushushu komoya. Ukongezelela, ukuvuleka kwezobuchwepheshe ngokukhawuleza kukhenkceka, kwaye ikhephu lingena kwigumbi ngokusebenzisa nayiphi na i-gap, ngoko akunakwenzeka ukusebenzisa "ukupholisa kwamahhala" iinkqubo zokutshintsha ubushushu.
Ngenxa yoko, indawo ye-insulation yeendonga kunye nemodi yokusebenza yekhabhinethi yokufudumeza ikhethwe ngokulinga.
Kwaye kwafuneka ukuba sisombulule lo mba nge-grounding loop kunye nokhuseleko lombane. Ingxaki iyafana naleyo yoogxa babo kwimimandla esemantla kwi-permafrost. Kuphela apha sasinamatye angenanto. Ukuxhathisa i-loop kutshintsha kancane ngokuxhomekeke kwimozulu, kodwa ihlala i-2-3 imiyalelo yobukhulu obuphezulu kunokuba buvumelekile. Ngoko ke, kwafuneka sitsale ucingo lwesihlanu kunye nombane kwisikhululo sombane semoto yentambo.
Iinkcukacha zesikhululo esisisiseko
Ukuqwalasela iminqweno yeSebe leeNgxaki zaseRashiya, ngaphezu kwesikhululo sesiseko se-3G, le projekthi yayiquka ukwakhiwa kwe-2G BS. Ngenxa yoko, sifumene umgangatho ophezulu we-UMTS 2100 MHz kunye ne-GSM 900 MHz ukugubungela yonke i-slope esemazantsi ye-Elbrus, kuquka indlela ephambili yokunyuka ukuya kwi-jind (5416 m) yesali.
Njengomphumo womsebenzi, izikhululo ezimbini ezisisiseko ezisasazwayo zifakwe kwi "site," equlethwe yiyunithi ye-frequency processing unit (BBU) kunye ne-remote radio frequency unit (RRU). I-interface ye-CPRI isetyenziswe phakathi kwe-RRU kunye ne-BBU, inika uxhulumaniso phakathi kweemodyuli ezimbini usebenzisa i-optical cables.
Umgangatho we-GSM - 900 MHz - DBS3900 eyenziwe yiHuawei (PRC).
Umgangatho we-WCDMA - 2100 MHz - RBS 6601 eyenziwe nguNokia (eSweden).
Amandla okuhambisa alinganiselwe kwii-Watts ezingama-20.
Isikhululo sesiseko sinikwe amandla kwiinethiwekhi zombane zeemoto zekhebula - akukho ndlela yimbi. Xa umbane ucinyiwe, abasebenzi abasebenzayo bacima isikhululo sesiseko se-3G kwaye icandelo elinye kuphela le-2G eliseleyo, lijonge ngase-Elbrus. Oku kunceda ukuhlala unxibelelana, kuquka nabahlanguli. Amandla okugcina ahlala kwiiyure ze-4-5. Ukubonelela ngofikelelo kubasebenzi kwizixhobo zokulungisa akufanelekanga naziphi na iingxaki ezithile xa i-cable car isebenza. Kwimeko yongxamiseko kunye nokunyuka kongxamiseko, ukunyuswa kweemoto zekhephu kubonelelwa.
