Oby\u010dejn\u00e1 kanalizace, kam se odpadov\u00e1 voda vypou\u0161t\u00ed. \u00b7 Mnoz\u00ed lid\u00e9 ani nep\u0159em\u00fd\u0161l\u00ed nad t\u00edm, jak u\u017eite\u010dn\u00e9 litinov\u00e9 poklopy jsou!

Vs\u00e1kly do asfaltov\u00fdch povrch\u016f? Samoz\u0159ejm\u011b, \u017ee ne. \u00b7 D\u00edky litinov\u00fdm poklop\u016fm se tak\u00e9 zam\u011bstnanci dostanou lehce k tomu, aby zkontrolovali hladk\u00fd pr\u016fb\u011bh pr\u016ftoku odpadn\u00edch vod. A \u017ee se st\u00e1le zmi\u0148ujeme o poklopech litinov\u00fdch?  Nen\u00ed divu, \u017ee je zm\u00ednka st\u00e1le jen o poklopech z litiny. Litina je slitina \u017eeleza a uhl\u00edku. A takov\u00e1 slitina m\u00e1 skv\u011bl\u00e9 vlastnosti. Je odoln\u00e1 proti teplot\u011b, tlaku, m\u00e1 n\u00edzkou m\u00edru pru\u017enosti. A tyto vlastnosti kvalitn\u00ed poklop pot\u0159ebuje. Nebo byste snad cht\u011bli, abyste se po \u0161l\u00e1pnut\u00ed na poklop zhoupli? Nebo, nedej bo\u017ee, propadli? Nemysliteln\u00e9, vi\u010fte?  A jen tak pro zaj\u00edmavost. Sl\u00e9v\u00e1n\u00ed bronzu je star\u0161\u00ed, ne\u017e sl\u00e9v\u00e1n\u00ed litiny. Prvn\u00ed zm\u00ednky o litin\u011b jsou zaznamen\u00e1ny v \u010c\u00edn\u011b, a to ve 4. stolet\u00ed p\u0159. n. l. Kde\u017eto do Evropy se sl\u00e9v\u00e1n\u00ed litiny dostalo a\u017e ve 14. stolet\u00ed. Trochu se zpo\u017ed\u011bn\u00edm, vi\u010fte? A tak\u00e9 je t\u0159eba zaj\u00edmav\u00e9 to, \u017ee prvn\u00ed zm\u00ednky o kanalizaci byly objeveny v Turecku na po\u010d\u00e1tku prvn\u00edho tis\u00edcilet\u00ed p\u0159ed na\u0161\u00edm letopo\u010dtem.
