Xa ufaka ucingo, awukwazi ukwenza ngaphandle kweensika, ezisebenza njengenkxaso yesakhiwo kunye nokukhusela ngokuqinisekileyo izicingo. Kuzo ezo zinto ziqhotyoshelwe kwifowuni, ingaba ibhodi edibeneyo, izitena , amabhodi ngamaplanga okanye i-slate. Kodwa unokukhetha njani iipolisi zomcingo, ukuba i-assortment inikezela ezininzi iintlobo zezakhiwo ezixhasayo? Ngalokhu ngezantsi.
Ukwahlulelwa kwezibonda zecingo ngohlobo lwecandelo
Ezi mveliso zinokuhlukaniswa kwamanani amaninzi, kodwa ezona ziqhelekileyo zikwinqanaba lomnqamlezo kunye nezinto zokuvelisa. Ngokuxhomekeke kwimiqathango yecandelo, zonke iikholomu zingafakwa kwiintlobo ezintathu:
- Iintsika ezijikelezayo zocingo . Ziyasetyenziswa xa kuyimfuneko ukunciphisa umlinganiselo womsebenzi womhlaba, njengoko ziyakwazi ukubhaptizwa emhlabathini ngokukhangela okanye ukuqhuba. Ukongeza, ii-lags ziqhotyoshelwe kalula. Ukuxhamla, ukulula ukululaza, kulula ukukhusela kwi-corrosion ngepende. Umgca osikiweyo unamandla aphezulu (malunga neetoni ezi-1.2 ngelogi), elona lihlandlo elingaphaya komthwalo obangelwa ngumoya.
- Iintsika zesikwele kwicingo . Banobunzima obukhulu be-flexural, kodwa ngenjongo yokufakela kufuneka ifaniswe ngokuthe ngqo kumcingo. Kodwa kukho enye i-drawback - indawo ye-lag ukuya kwipayipi iba ngumthombo wokubola, ongenakuvalwa. Oku kubangelwe ukuba inqwelo engavaliyo yokuvuthwa yenziwa kwindawo apho iibhobho zifihla khona, apho amanzi angagcina khona. Yaye le yimeko apho intsimbi ihlahlela ngokukhawuleza. Umgca weld wandisa kuphela imeko. Kwaphela iminyaka engama-3-4 i-spike ene-welded iyatshatyalaliswa ngokupheleleyo kwaye ucingo kufuneka lulungiswe okanye lutshintshwe. Ukongeza kwintsilelo echazwe, kufuneka kwakhona kuqaphele iindleko eziphezulu zeemveliso (ityhubhu yesikwele iluhlu olungaphezulu kweyure elifanayo kunye nexabiso layo li malunga ne-30% phezulu) kunye nobunzima bokufakela (kubalulekile ukuba ubuso obunye bexande lukwindiza efanayo kunye nocingo).
- Gweba izithuba zocingo . Umbono olungeleyo weembalo, ezinesipoti ekugqibeleni kunye nomtya. Ziyakwazi ukufakwa kuyo nayiphi na impumulo, ngaphandle kokusebenzisa amandla okucima. Ngokuxhomekeka kwintambo, ungakhetha ububanzi bebumba. Ngoko, ukuba igridi inqwaba ye-55 mm iyakusondela, kwiprofayili yentsimbi - ububanzi be-76 mm.

Uluhlu lwecandelo lubalulekile xa kubalwa izindleko zocingo kunye nesantya sofakelo.
Uluhlu
Iintlobo ezithandwa kakhulu yiintsika zensimbi zomcingo. Zihlala zizinzileyo, zidibaniswe ngokupheleleyo kunye naluphi na uhlobo locingo kwaye zingasetyenziswa kwakhona. Imilenze eyenziwe yensimbi isetyenziswa rhoqo xa ufaka ucingo lweshidi elifayiliweyo, iintonga zensimbi okanye i-slate flat. Ngaphambi kokufakela, izithuba kufuneka zenziwe peyinti ukukhusela ukubola kwesimbi kwithuba elizayo.

Ukuba ufuna uhlahlo lwabiwo-mali, ungasebenzisa izibonda zokhuni. Bangakwazi nokuba neklasi okanye isigaba esinqamlekileyo setyhula. Ngaphambi kokufakela, izibonda kufuneka zicutshungulwe, umthi uphathwe kakhulu kwimpembelelo nomoya. Inxalenye eya kungcwatyelwa emhlabathini kufuneka iphathwe ngokunyanzelwa kwe-bituminous, eya kwenza ukukhutshwa komthi ngamanzi kunye nama-acids. Ingxenye ephezulu yenkomo ingaba nepeyinti enebala. Ngaphambi kokucubungula, ungalibali ukuma kwaye uphuthule imilingo.

Izibonda zokuhlobisa ucingo
Abanye abanikazi babhekisela kwipheno njengesakhiwo esikhulu, esiza kusebenza njengokhuselo kunye nokuhlobisa indlu iminyaka emininzi. Kwaye ukwenza iyingxenye ebalulekileyo yefowade yendlu, izinto ezinje zokugqiba izitena, ilitye lasendle kunye neebhloko zokucingo ezikhethekileyo zisetyenzisiweyo. Ukumisa ityitye okanye insika yetyholo yocingo, kuyimfuneko ukuba uzalise isiseko kwaye ulungiselele ubumbano ngokwecebo elikhethiweyo. Umsebenzi unzima kakhulu, kodwa umphumo wokugqibela ufanelekile umzamo.
