Grillage: kuyini futhi ziyini?

Eminyakeni yamuva nje kuye kwaba waba ukwanda okukhulu kwezincwadi ivolumu ukwakhiwa. Ngakho-ke, Sinesithakazelo esikhulu izinhlobo izisekelo esetshenziswa. Ngokuvamile, ukwakhiwa kwezinye izakhiwo ezincane ezisetshenziswa grillage. Kuyini lokhu? Ngakho embonini yezokwakha abizwa ngokuthi imishayo noma slabs, okuyinto asethe njó yinqwaba ezijulile angcwatshwe. Ku-ukwakhiwa kwalo, ngokuvamile yimani niqonde okugeza. Ngaphezu kwalokho, abantu abalwazi kahle ulimi strip isisekelo isihlenga, lapho ububanzi likhulu kakhulu.

Ngeshwa, uma kungukuthi usuwake wayisebenzisa lolu hlobo isisekelo ukuze kwakhiwe indlu, khona-ke bambe egumbini ngeke aphumelele. Nokho, unikezwa yokuthi isisekelo isihlenga (kuyini, kuye kwashiwo ngenhla) ngokuvamile efakwe nenhlabathi okuxekethile kwezimo abasebenza ngaphansi kwazo Iqhwa, lokhu yokusilela akuyona eziphawuleka ngokukhethekile.

Indlela ukukhetha inqwaba?

Ngokuvamile, abakhi zisebenzisa ukhonkolo, ngokhonkolo njalo nakakhulu futhi steel yinqwaba. zinhlobo kakhulu ezingavamile izinkuni esetshenziswa. Modern isisekelo - isihlenga isisekelo - ukwenza usebenzisa yinqwaba, kodwa evame ukusetshenziswa hlobo nemijovo, lapho ukwesekwa ethelwa ngokuqondile ezinhlamvwini endaweni. izinhlobo ezinhle kakhulu futhi Precast, okuyiwona ukufakwa ufuna ukusebenzisa imishini ekhethekile.

Ukuze grillage (okungukuthi, vele sesiyazi) ukuthola okunokwethenjelwa, udinga njalo enze izinyathelo ngezansi. Ukuze uqale, kufanele wazi ukuthi ezimweni eziningi, kuthatha impela eningi yinqwaba, okuyinto zitholakala at ibanga 1.5-2 amamitha ngaphandle. Njengoba isivikelo umswakama isetshenziswa noma asbestos usimende ipayipi, noma ikhoyili ka esiku impahla ukufulela.

Okokuqala, kunengqondo ukufuna usizo inkampani geodetic, okuyinto ochwepheshe eyonquma enhlabathini, linqoba endaweni yangakini. Ngeshwa, iningi akazange acabange ukuthi kungani ngezinye izikhathi zinqwabelane isisekelo isihlenga ngaphansi imithwalo esindayo kakhulu, okuyinto bungase buholele ukusonteka ngisho nokubhujiswa izindonga.

Okungukuthi ukuze azivikele imiphumela enjalo enqabayo balungiselela isihlabathi isiguqo design kuvimbela ukusonteka ngenxa emhlabathini ukunyakaza.

Yamba izimbobo for yinqwaba, futhi ungakhohlwa mayelana lokuthi ngokushesha ibekwe asbestos-usimende amapayipi noma ukufulela impahla, ayezosebenza njengabaqondisi umswakama isithiyo. Ngaphakathi valve sifakwe, okwathi ngemva kwalokho ekhiqizwa ethela ukhonkolo nodaka. Kufanele kuqashelwe ukuthi nokufakwa kwamanzi Wheel kumele aphume ashone ngaphezu kwamanzi inhlabathi: ukuthululwa isisekelo isihlenga ke kudingeka ixhunywe ku kwesisekelo salo.

Ngemva ukuqinisa efanele izisekelo isakhiwo sonke ligcwele ukhonkolo. Ngomqondo onabile, isakhiwo esinjalo, futhi ngesizathu esihle kungenziwa ngokuthi i izisekelo strip inqwaba. Kufanele kuqashelwe ukuthi i-tape ngokwayo alaneliswa ngokushesha emva kokuphothulwa umsebenzi nge yinqwaba. Ngaphezu kwakho konke, isisekelo isihlenga is concreted ngokwayo esikhathini esingangesonto. Phawula ukuthi njengoba ugcwalisa ukusetshenziswa ezinhle polystyrene enwetshiwe okuxekethile, ngokumangalisayo ekuthuthukiseni nangokuvikela ukhonkolo.

Ngakho thina ngaye isisekelo simuke namanzi. Kuyini futhi ziyini, manje uyazi!
