Description
Szyby zamrazane sa dotychczas wy¬ kladane lanemi wiencami szybowemi lub tez zelbetonem.Obudowa z lanych wienców jest co- prawda szczelna, lecz nie posiada dosta¬ tecznej odpornosci, przy wielkiej grubosci pokladu kurzawki. Obudowy, wykonane z zelbetu, dla szybów zamrazanych wy¬ trzymuja wprawdzie cisnienie, tworzace sie przy roztapianiu gór, lecz nie sa w do¬ statecznym stopniu wodoszczelne.Wynalazek niniejszy dotyczy sposobu wytwarzania tego rodzaju znanej obu¬ dowy z zelbetu, prowadzacy jednak do zupelnego uszczelnienia scian i nie prze¬ puszczania wody. Z poczatku wytwarza sie obudowe na calej glebokosci szybu z konstrukcji zelaznej, zaopatrzonej w zna¬ ny sposób w zewnetrzna okrywe blasza¬ na i zapelniona ztylu betonem o malej za¬ wartosci piasku. Konstrukcje zelazna wy¬ konuje sie tak silna, ze sama ona moze wytrzymac cale cisnienie hydrostatycz¬ ne po roztajaniu góry. Po roztajaniu u- szczelnia sie okrywe blaszana i wklada po kolei wypelnienie betonowe.Z korzyscia wypelnia sie, celem rozta- jania, caly szyb woda i ogrzewa sie ja, np., przez przeprowadzanie pary. Woda przy¬ spiesza roztajanie i wytwarza na okrywie blaszanej wewnetrzne cisnienie, przeciw¬ dzialajace cisnieniu góry. Po roztajaniu odwadnia sie nastepnie szyb krok za kro¬ kiem i uszczelnia okrywe blaszana. Teraz dopiero wytwarza sie odstepami obudowe betonowa, na która juz nie moze oddzia¬ lywac szkodliwie dzialanie mrozu.Jak tylko stezeje jeden odstep betono¬ wy, moze byc porowaty beton, za okryweblaszana, uszczelniony oraz wzmocniony betonem cieklym. PLUntil now, the frozen panes have been lined with lane and glider wreaths or reinforced concrete. The cast wreath casing is airtight, but it does not have sufficient resistance due to the great thickness of the dust bed. Although reinforced concrete housings for frozen shafts withstand the pressure generated by the melting of the mountains, they are not sufficiently watertight. The present invention relates to a method for producing this type of known reinforced reinforced concrete housing, however leading to a complete seal. walls and not passing water. Initially, a casing is produced over the entire depth of the shaft from a steel structure, provided in a known manner with an outer sheet metal covering and filled with low sand concrete. The iron structure is made so strong that it itself can withstand the entire hydrostatic pressure after thawing the top. After thawing, the sheet metal is sealed and the concrete filler is put in successively. The whole pane is preferably filled with water for thawing and it is heated, for example, by passing steam. Water accelerates thawing and creates an internal pressure on the sheet metal, counteracting the pressure on the top. After thawing, the shaft is then drained step by step and the sheet metal is sealed. Only now are the spacings made of a concrete casing, which can no longer be adversely affected by frost. As soon as one concrete gap is fixed, it can be porous concrete, covered with a casing, sealed and reinforced with liquid concrete. PL
