Ukuthululela ukhonkolo ngaphansi kwezimo ezikhethekile

Abaningi kwakudingeka abhekane nesimiso inkinga ukuqaliswa izibopho ukhonkolo, ikakhulukazi ebusika. Ukuthululela ukhonkolo ebusika kuyahluka kakhulu emsebenzini onjalo, okuyinto kwenziwe ehlobo, futhi kudinga ulwazi ezicini ezithile.

Enye izifundo esikoleni kusukela physics yaziwa ukuthi amanzi kwamakhaza ashubisa umnkantsha kuthatha ngesimo okuqinile, isb ludlulele ice, okuyinto izikhathi eziningana umthamo wamanzi siba sikhulu. Ngakho-ke, lapho ethela ukhonkolo amanzi ebusika indlela ezivamile, ingxenye yiqhwa isixazululo, oluvimbe inqubo solidification futhi yakha amakhefu umqulu.

Sahlazo kukhona ukhonkolo lokushisa amaconsi. Kuphelile, asikwazi ukuthi akekho kunanoma yisiphi isimo, kodwa ngemva incibilikiswa okuphindaphindiwe okokuqandisa, ethela ukhonkolo phakathi formwork anganika zero yi.

kanjani ukukhiqiza imisebenzi ukhonkolo emakhazeni?

Ukusebenza izixazululo ukudala ukulingana kwasekuqaleni kumele kwenziwe imithetho jikelele ezikhona ukwakhiwa. izidingo ezimbili ukusebenzisa. Okokuqala, ukudala izibopho kudingeka ukulungiselela eliphezulu, ukuhambisana ukhonkolo. Ekulethweni esizeni yayo kangcono ukusebenzisa ukhonkolo. Ngaphezu kwalokho, omakhi kubeka umthwalo ukulungiswa isikhala esizayo ethela futhi eminye sokwelapha.

Lokho ikhambi esesindile kahle, izonikeza cishe amaphesenti angu-75 amandla alo, kubalulekile ukudala izimo lokushisa ukulondolozwa. Ukuze qualitative okuqinile ukhonkolo screed ukugcwaliswa kumele kwenziwe ngesikhathi lokushisa 10 ngenhla zero. Ngakho-ke, umsebenzi esikhiqiza screed kumele kwenziwe endlini efudumele, esesikhundleni izindonga, nophahla bafudumale.

(Nokho, okuyinto izinga ubuncane lapho ungakwazi ukusebenza nge usimende, ngesikhathi elapha ngezinye izikhathi lenyuke) Lapho ukhonkolo ethela ikhiqizwa endaweni nge lokushisa kuma 5 degrees kufanele uthathe izinyathelo ezilandelayo. Okokuqala, ukusetshenziswa for izithasiselo ukhonkolo noma izithasiselo chemical (akunconywa ukudala izibopho) ngoba braking inqubo okokuqandisa. Ukhonkolo kumele batheleka formwork, okuyilona elidingekayo ukuze pre-efudumele. Formwork ungakwazi afihle ukufulela wazizwa, amaminerali uvolo, solomitom, kamyshitom futhi phakathi amabhodi ugcwalise slag, sawdust noma bagcwalise isikhala amagwebu. Ingasetshenziselwa for amalahle infrared ukushisa imithombo etholakalayo. Ngaphezu kwalokho, fillers ukufuthelana: amanzi, isihlabathi noma amatshe.

Kule kusobala ukuthi indlela engcono kakhulu ukuqinisekisa solidification evamile yesixazululo kanye microclimate efiswayo ingumuthi ukusetshenziswa kwesihenqo emoyeni, futhi isicelo umthombo ukushisa, uma ukufakwa ledzingekako kagesi noma igesi ukushisa izibhamu.

Kumele kukhunjulwe mayelana nemithetho yokusetshenziswa Ukushisa imishini. Engafanele efakwe ukushisa isibhamu uzokwenza okwengeziwe umonakalo izibopho eyodwa esifundeni kungase wome, kanti eyesibili - nqabela.

Uma ukuthelwa ukhonkolo Kwenziwa kuhambisana nemibandela kanye nokwesekwa okuqhubekayo (mayelana 4-5 izinsuku) umbuso ezishisayo, for izinga layo abakwazi ukhathazeke.

Ngezinye izikhathi kuyenzeka ukuthi ukhonkolo eqina ngenxa yamakhaza. solidification wayo ingabuyiswa ngokubheja ngenhla zero lokushisa (hhayi ngaphansi kuka 10 degrees). Kuvamile lokhu ngesikhathi yesithwathwa ekwindla. Kodwa kulokhu, awukwazi ukusinda umonakalo onjalo abandayo ezinkulu ukhonkolo ngeke akwenze. Kungaba ubhujiswe kuphela engenhla ungqimba elincanyana.

Uma uthayi buhlangene, nesidingo esiphuthumayo alisibekele ifilimu obukhulu polyethylene ngenyanga futhi uma kuncibilika iqhwa akababhubhisanga ukhonkolo. Kulokhu amandla Kuthi aphansi, kodwa lokhu kuphela isendlalelo engenhla.
