Botha concrete wire PNSV: ingqokelela icebo kunye necebo

Botha scheme eziphathekayo ukubekwa wire PNSV neya echazwe ngezantsi, kusetyenziswa xa besebenza ngaphandle ebusika. zazo Ezo eyimfuneko ngenxa yokuba xa phantsi kubushushu obuphantsi isisombululo kancinane uyaqala ukufumana amandla, oko nje amanzi iqalisa ukutshaza ibe ngumkhenkce. ukuqaqadeka elide ikhonkrithi isizathu sokuba umsebenzi yayiqhubeka iiveki neenyanga, ukongeza, kukho kungenzeka ukuba uyilo akuthethi kufumana amandla efanelekileyo iya ukuwa iyasetyenziswa.

Umgaqo esebenza ngayo wire

wire eziphathekayo zifudumele technology PNSV silele yokuba phambi kokuba kuqale ukulahlwa uthabathe ayimfuneko cable cross-candelo kunye stress ibhuqiwe, uze emva koko wathulula. Ngoko ke ngentambo eziplagwe kulo. Musa ukoyika ukuba umgangatho eziphathekayo ziza kutshintsha phantsi kwempembelelo lobushushu eliphezulu, amadlu musa ayikhangeleki njengokuba iintanda emva ephilisa, kodwa inkqubo ephilisa abuyi wayeka kwamaqondo obushushu aphantsi, nto leyo eza kunika uyilo eqinileyo nethembekileyo.

iimpawu iingcingo Technical ukuba eziphathekayo

Wire ukufudumeza eziphathekayo PNSV lidla ezinye iimpawu ezikhethekileyo. Le umqhubi ngokuqhelekileyo yangoku-ekuthwaleni, esingaba ukutyabeka ubushushu. Ukhuseleko kufuneka senziwe ipholiyesta okanye Polyvinyl chloride. Xa ubukhulu ngu 1.2 mm, kodwa umlinganiselo ukumelana elingana 0,15 Ohm / m. Ungayisebenzisa kuluhlu lobushushu -60- + 50 ° C. Xa umsebenzi, ngoku inokuba kulingana 14-16 amperes.

Ukubeka enokwenziwa kwi -25- + 50 ° C. Phambi kokuba uthenge kufuneka ukumisela kusetyenziswa mangaphi iingcingo, ukuze ngenxa 1 m ³ isisombululo kuya kufuneka malunga 55 m.

Winter ukufudumeza eziphathekayo cable PNSV ekhuselekileyo ngokupheleleyo, ngenxa yokuba kuveliswe le mveliso ifumana yokugquma esemgangathweni ukunqanda umlilo. Akukho phantse akukho ingozi ukuba ophilileyo eyaphuke, njengoko anele. akufuneki actuate kwicingo gama nje akayi batywiliselwe isisombululo. Kungenjalo, uya ecima ngenxa ngoku landa. Nangona kunjalo, izigqibo ningoyiki izinto ezinjalo, kuba iqanjwa iingcingo ngaphezu umdla cross-candelo, ehambisa iziphelo ekuthiwa-ebandayo. Bona ezenziwe APV-4, ubude oluyi-1 m.

Ububanzi bokusebenzisa

Iindlela ngokushushubeza ucingo PNSV eziphathekayo kubandakanya ubuchule ukulisebenzisa nje kuphela ekhaya, kodwa ngendlela mveliso. Ngamanye amaxesha yavelisa ekufakweni

iziseko kunye neengcingo.

Ndiqhuba ufakelo cable

Ukusingatha ezintambo ithetha yokuphatha uxanduva. Phambi kokuba uqale inkqubo ngokubekwa, kuyimfuneko ukukhulula kumphezulu kobutyobo kunye izinto zasemzini esebenzayo ezo zinto ukuba kunokonakalisa wire. Ebudeni oku kubalulekile ukuqinisekisa ukuba intambo leyo angazange aguqe. Kucetyiswa ukuba ukuphumeza engamzondi kwisangqa, kodwa akufuneki ukuba abunjwe kwimimandla ezingenanto. Njengoko indlela ingqokelela kakhulu elula izenzo inyoka.

Emva kokutshintshela kwindlela imfuneko ukuqhubeka ngobulumko. Ngoko ke, kufuneka kubekho utshintsho ombane, ukuphumeza le njongo ufuna ukusebenzisa somfanekiso, kungenjalo kwicingo nje ecima kwaye susa oko akuyi kuba lula.

Ukuncoma scheme wire concrete PNSV apho kweli nqaku. Wakuba ukusiqhuba ku umkhuba, unako ukuvelisa ndikuzalisa kanye uqhagamshelwano, nto leyo equka UPawulos intambo umbane. Akukhuthazwa ukuba zisetyenziswe xa kuthelekiswa nesiguquli. Njengomgaqo, iingcali bacebisa ukusetyenziswa esitishini ukufudumeza brand SPB-40, SPB-80.

Uqhagamshelwano kwenziwe iziphaluka ezibini zombane, owokuqala ekuthiwa i "nkwenkwezi", ngoxa yesibini - i "unxantathu". Kwimeko yokugqibela, iingcingo kwi ngocingo zahlulwe iinxalenye 3 alinganayo kunye neengcingo nganye interfaced ngaxeshanye. Iiseti kwakhiwa kufuneka adityaniswe kwi esiludumbo 3 idityaniswe kwiitheminali isikhululo 3.

Iimpawu ze imfudumalo-up

Phambi kokuba uqale ngoko ke kufuneka ukwazi efudumeleyo eziphathekayo wire PNSV.

Ngeli xesha lokuqala, umxube uya shushu, ngaloo ndlela ngokungamkelekanga ukwandisa lobushushu lingaphezulu kwe-10 ⁰ C iiyure ezimbini. Ithuba lesibini kufuneka sikhatshwe ukunyuka kwamaqondo obushushu ngaphezu 80 ⁰ C. Ngelo Inqanaba lokugqibela le pholisa. Kulo mzekelo, naye, akufuneki sukela kwaye akufunekanga ibe ngaphezulu kwe-5 ⁰ C ngeyure enye ukwehla.

Botha concrete wire PNSV scheme kabani ingqokelela esichazwe apha, ohluke kakhulu ukusuka obandayo iteknoloji inkqubo "umgangatho efudumeleyo". Ukongeza, le ntambo kunokuba babandakanyeke ekuphumezeni ezi njongo. Nangona kunjalo, le nkqubo iza kufuneka ukugqiba kancinane, izakhiwo imicwe heater ye kwiindawana, lo gama encotsheni yale nkqubo kufuneka zikhuselwe usambathisa.

Ixabiso le-zokufudumeza cable

Phambi kokuba uthenge udinga ukuziqhelanisa wena kunye namaxabiso intambo. Kwiindawo ezahlukeneyo kulo malini ngeendlela ezahlukeneyo, kodwa ixabiso avareji kuhlala ingatshintshanga, nto ilingana engange-2. / M. Akufunekanga uthenge imveliso ngaphandle kokukhangela ukuba siyafana imigangatho zikarhulumente lusekiwe, ngoko intambo iveliswa ngokwemigangatho 12.1.013-78.

Ndiqhuba processing eziphathekayo emva ukufudumala

abakhi abaninzi bezibuza ukuba kunokwenzeka ukulawula ukusika okanye yokomba eziphathekayo emva ezuza amandla. Olu daba ibangwa kukuba ngexesha kokumisa nangoku uyilo ukufudumala a kundinqabele amandla kwibakala. Phendula lo mbuzo HIV, kodwa bamathidala. Sika, nangona kunokwenzeka, kodwa akwamkelekanga ukuvelisa kukothuka. Isisombululo ifanelekileyo kulo mzekelo isebenza ukusetyenziswa kwezixhobo idayimani. Ngoko ke, ukuba usebenzisa umsebenzi kwesi sigaba diamond zokomba, emingxunyeni concrete inzuzo elintlangothi agudileyo, neentanda akuyi kwenzeka. Ngaphezu koko, ukuba ukubaqhelisa umzimba eziphathekayo yi kancinane nedayimani, ngoko ukutshintsha isixhobo ngexesha semigudu weyisayo musa loo ilungelo ufakelo lwesamente.

izincomo isazi

Botha concrete scheme wire PNSV engamzondi leyo nqaku kuveliswa coiling kwayo okokuqala kwi iintsimbi, ngoko kuyimfuneko ukuze kuqinisekiswe ukungabikho uxinzeleko. Uyakwazi ukubeka ngokulula phakathi iziqalelo ifreyim yesinyithi. Kufuneka kukhunjulwe ukuba wire angamchukumisi kumphezulu formwork, ezivelileyo kulo mzimba eziphathekayo emva kakhulu awaphalaza akufanele.

Intambo ukufudumeza ingafakwa kuphela emva kungekabekwa yesakhelo kugunyaziso sele yenziwe, akukho mfuneko yokuba baqale ekuqhubeni le misebenzi de kufike ixesha lokuba izinto eziqulethwe akayi kuvela isithuba isakhiwo ziluvingcile. umsebenzi welding kufuneka igcwaliswe ngeloo xesha. Botha wire PNSV eziphathekayo scheme kabani ingqokelela iboniswe kulo mzobo, kufuneka kuqhubeka emva ephilisa solution-50%.

Ubushushu ezithi zivele kwi engundoqo kufuneka ibe nako sifudumeza isisombululo 40-800 ⁰ C. Ixesha de mxube abaphumelela amandla epheleleyo, ziya kuxhomekeka iimpawu into, yaye ngokuqhelekileyo kuthatha iintsuku ezintathu. station Ukuzifudumeza-up kufuneka luphinda-ukusebenza imida elifutshane okanye elide. Inyathelo phakathi kwala macingo akufunekanga ibe ngaphezulu kwe-15 mm.

wire eziphathekayo zifudumele PNSV ubalo linikwa kwi nqaku, kodwa nokunyanzeliswa kwaso asisiniki impumelelo epheleleyo. Kakade ke, kubalulekile ukuba uthathe ingqalelo nobuchwepheshe ufakelo ekucetywa ukuba ecaleni wire zoqhagamshelwano okanye waliwela. Ukuze ukwazi ukulawula ubushushu isisombululo kwezakhiwo ayenamandla, kuyimfuneko ukuba wenze umgqobho okhethekileyo. Asimele uqale inkqubo ukuzifudumeza ukuya mzuzu de isisombululo wabeka ngokupheleleyo, ekubeni kuchasene yezizathu zokhuseleko, ukongeza, oko kunokonakalisa wire. Kukhethwa ukuba owonithemba nokuphunyezwa iingcali msebenzi, njengoko ufakelo cable lukhatshwa neengxaki ezithile kwaye ifuna izakhono master ekuqhutyweni zazo ezinjalo.

Wire ukufudumeza eziphathekayo yokubala

Ngenxa yoku kulapha ngasentla, sinako ukuzoba kwisigqibo ilandelayo: 1 ^{m3 of} eziphathekayo kuya kufuneka ukuchitha malunga ne-55 leemitha of cable. Ukuze kubalwe le ucingo, kuyimfuneko ekuqaleni ukufumana kangakanani yezisombululo obegalelwe kulo formwork. Ngenxa yoko, umxube 20 m ³ kumelwe 1100m.

Umsebenzi wokwakha jikelele Kukhethwa ukuba enze ngexesha kwiinyanga ezifudumeleyo, okuyinene ngokukodwa nabaphuhlisi abazimeleyo. Njengomgaqo, ulondolozo ukugalelwa ikhonkrithi kwixesha abandayo kungenxa imfuneko ukwenzeka into ukusa kwixesha elithile. msebenzi kwi ukwakhiwa ekhaya zibandakanya iindleko ezongezelelweyo ukulungiselela ukufumana ongeziweyo nokubanda, ukufudumeza iintambo kwakunye nezinye izinto. Ewe, kwaye iindleko zabasebenzi ebusika xa eziphathekayo obegalelwe kunzima kakhulu ngakumbi kuba ibhetshi iza unikezelo elandelayo umxube ngokuvumelana formwork.
