Ngesikhathi kuvubukulwa nezinhlobo zayo

Ngesikhathi kuvubukulwa - umgodi esenzelwa e idwala emva kumbiwa kwenza amaminerali kanye amatshe.

Kuye injongo, umsebenzi kanye rock zihlukaniswe izinhlobo.

Incazelo yenqubo

ezimayini ezingaphansi komhlaba libhekene kuleso sigaba yayo cross has umbuthano avaliwe, kungakhathaliseki kukhona ukufinyelela ngqo ebusweni. Ngaphezu imisebenzi komhlaba abazenzi ukuthi run anjalo phasi. Kumbiwa evulekile evulekile iluphu cross kwesigaba.

Lapho indlela komhlaba usebenza, kungaba:

- izimayini kanye ukuhlola;

- izimayini kanye dolobha;

- izimayini kanye nokulungiselela;

- threaded;

- mortgage;

- yokuhlanza.

Ngesikhathi kuvubukulwa, ngokuya ngendawo okuyiwa kuyo, kuyinto ukuhlola production. Eyokuqala osetshenziselwa ukuhlola search for imali entsha, kwesibili - sokuthuthukiswa ezifakwa ukuze kukhishwe kusukela namaminerali kugcwele. umsebenzi Isondlo kuthiwa selihlukene laba kuveze ukulungiselela ukuhlanzwa.

yokwemba Ukudalula yakhelwe ukuvula eyami kanye nokufinyelela zemfundo izidubedube.

Ilungiselela umsebenzi kuyalungiswa sokuthuthukiswa inkambu okwami, futhi inqubo ukuhlanzwa we amaminerali ore zikhishwa.

Buka edwaleni inquma kumiswa noma ukuthuthukiswa kuyoba ensimini. Kokuthoma ibekwa phezu kwesigubhu, kwesibili - edwaleni imfucuza.

Ngesikhathi kuvubukulwa lungaboniswa futhi ivolumu ukuthi kunqunywa lihlela isilinganiso phakathi kwama kwesigaba longitudinal kanye cross kwesigaba endaweni edwaleni ngayo. Enwetshiwe, ngaphezu, kukhona ovundlile, enalokho kuthambekela futhi mpo.

Vula yokwemba sehlukaniswe imisele, emiseleni, imithombo, congresses.

kwesigaba engu-

Isiphambano ukuma Sectional indlela evundlile incike izakhiwo idwala bese isimo sazo, isiqondiso namandla idwala ingcindezi, ubude isevisi kanye isakhiwo support.

Arched ukuma cross-Sectional unamathisele ekwakhiweni, okuyinto alinamathiselwe, njengoba okulingana ukuma lwaleli zemvelo.

Uma kungekho i-lateral ingcindezi imishini yokusaha izingodo, unxande ukuma cross-Sectional isetshenziswa. Kulokhu, okukhiphayo kuyinto ugodo esinqunyiwe, ezihlangene noma espagnolette lokubopha.

umumo trapezoid umelana kokubili ingcindezi mpo futhi lateral. Ukukhweza wenziwe ngokhuni, ukhonkolo Precast nensimbi.

Isigaba engu- nakho kungaba ukuma isiyingi, arched futhi arched.

ifomu Arched esetshenziswa ukhonkolo wokwakha kokungathembeki.

fastener Arched elisetshenziswa ingcindezi mpo futhi lateral edwaleni. Kulokhu, ukuthuthukiswa uqiniswa metal nemengamo.

Lapho ukucindezela kwabanye eliphelele kangcono isiyingi ukuma cross-Sectional. Uglespusknye imithombo ayikwazi ukulungiswa nhlobo. Elliptical kwesigaba engu- isetshenziswa, uma omunye ingcindezi kakhulu ezinye izingxenye.

Ngenkathi kwakhiwa imihubhe, izakhiwo wokubacindezela, ngezitimela ezigcwele esetshenziswa empambana okweqanda nge eksisi evundla mpo. umumo Sectional incike inhloso senzelwe yokwemba, kanye kusukela izimo yezimayini. Ikakhulu, i-vector ukuma kuthinta esiphezulu umthelela ingcindezi izingxenye, okuyinto abe-eksisi parallel we lesiyingi.
