Kungani mgodi ihlanganisa round - ke kuyimfuneko noma isiko?

Kungani mgodi nesembozo round? Futhi lokho basengaba? Kwakucatshangwa ukuthi the dweba kungaba ukuma isikwele noma unxande. Kodwa a design okunjalo, kunalokho - okuhlukile ngokuqondene nalo mthetho. Dweba - akuyona imbobo lula, kumele ngokuphephile ivaliwe. Kufanele kube lula ukusebenza futhi ephephile ukuyisebenzisa.

Uma lula - kungcono i amateur, ezingeni zokulawula, ukuthembeka umthwalo linganikeza round cap design. It incike ukuma ukucushwa base okuyilokho, eqinisweni, kuyinto mgodi amapayipi.

isimiso sokuthutha indle

Sewer inethiwekhi - a eziyinkimbinkimbi zezakhiwo eyenzelwe ukuqoqwa nokususwa wamanzi anokungcola achithayo kusukela luhlobo ukuphathwa kubasebenzisi. Lokhu kalula kakhulu kwenziwe ngosizo Izinsiza ngomshoshaphansi. Dug nomsele, yabeka ipayipi, okuzokwenza angakhishwa lamanzi anokugcola.

Ukuze sikwazi ukwenza isevisi uhlelo emva ibanga elithile ukuhlola okudingekile kwemayini. Ngokuya ingqalasizinda ezisemadolobheni kanye izakhiwo obukhulu ithuba indle kuphela emigwaqweni noma ngokuqondile ngaphansi kwabo. Kulokhu, lo vehicular traffic kubhaklazeka kufanele aqiniswe ivaliwe. Kodwa kungani mgodi ihlanganisa round? Kufanele abe namandla anele ukumelana esiphezulu kungenzeka umthwalo ezokuthutha.

Edolobheni elikhulu inani manholes futhi zonke izinhlobo ezimayini kungaba amakhulu ezinkulungwane. Akukhona indle kuphela, namanje inethiwekhi zokuxhumana: amanzi, Ukushisa, ugesi, igesi, ucingo nokunye.

manholes

Ukuze kube lula ukufinyelela wezokuxhumana kushaft kahle ngokuvamile eyenziwa esiyindilinga ukuma. Ikhala amapayipi esetshenziselwa ukwakhiwa izakhiwo ezinjalo, ngokuvamile sasakhiwe ngokhonkolo nakakhulu.

Ukuma cylindrical womthombo afanelekile kakhulu isevisi. Kulezi ezimayini ukukhiqiza umsebenzi ngokunethezeka. Ziyakwazi efanelekayo ukupholisa, kusukela nokusakazwa emoyeni into bunjwa cylindrical okukhulu ngaphezulu.

Usayizi ikhava endaweni base futhi ububanzi kwangaphakathi ekhethiwe ngokuvumelana ngenhloso yokubuka le kushaft. Kulokhu, zonke izakhi ze-uhlelo kuyoba okuhambisana kakhulu. Ucabangela indawo, kungenzeka umthwalo, traffic umfutho.

Kungani mgodi nesembozo round?

It incike ukuma ikhava. Ngakolunye uhlangothi, izisebenzi kumelwe kube lula ukufinyelela Izinsiza ngomshoshaphansi. Ngakolunye uhlangothi, i-kahle kumele ngokuphephile ivaliwe ukuze uvimbele noma yikuphi ingress lezinto angaphandle, ukuqinisekisa ukuhamba ephephile labahamba kanye traffic. Isivalo esijikelezayo kangcono salokhu, ngakho kumele kube umumo dweba.

Kuye injongo bahlukene ngokuvumelana uhlobo ukuxhumana, wabeka ngaphansi kubo: ubunjiniyela ikhebula amanethiwekhi, amanzi, igesi amapayipi, Ukushisa amapayipi, isiphepho amanzi angcolile amanzi. Usayizi owawugcwele emazweni ahlukahlukene lihlukile. ERussia, ubukhulu standard (645 kanye 800 mm) zivame kakhulu asetshenziswa. Kubhaklazeka, ekhiqizwa hhayi ngezindinganiso isimo, yakhelwe futhi lakhiwa abakhiqizi ngokuhambisana oda nezimfuneko enqophileko.

Kungani kuyinto cover mgodi round?

Lokhu kulungiselela kunezinzuzo eziningana. Ngaphambili kubhaklazeka zazenziwe ezihlukile. Zingaba iinkwere, uncamane, okusaqanda ngisho unxantathu ukuze ukhombise isiqondiso kwamanzi. Nokho, ukuma esiyindilinga ikhava kwenzakala efaneleka kakhulu.

It alusoze lwaphela nanini ngaphakathi kahle, njengokungathi ayibuyi. Simbonyo isiyingi lula ukuvula, ngakho iphuzu phoqelela uhlelo lokusebenza kuphi mbuthano ngeke kuphinde kube njengasekuqaleni. Kungaba iphuma, wagqoka onqenqemeni. Ngo womshini isakhiwo esinjalo umnotho oholela kangcono.

Ukuma esiyindilinga ikhava lingaphansi kuncike subsidence. Kungaba ukumelana umthwalo omkhulu nge ukushuba ofanayo, okusho ukuthi zingenziwa ohlabayo ngaphandle kokwehlisa izinga lawo. Esikhathini ukukhiqizwa Castings round ube iphesenti eliphansi izici (izimbobo emazinyweni, ikhule ezimbotsheni, izimbotshana).

impahla

Kumila kanye cover mgodi ngoba ezibucayi manholes ngokuvamile enziwa cast iron. Le nto has a amandla, okuyinto eyenza umthwalo esithwele futhi ukugqwala ukumelana okwesikhathi eside ekuphileni inkonzo. Isisindo izakhiwo eyanele ukuthutha isihambi ayikwazanga engaqondile phakamisa bese ushelelezisa ikhava. Sakaza yensimbi nesembozo akhiqizwa sokuncibilikisa izinto zokusetshenziswa secondary, ishibhile nozakwabo steel.

Ezindaweni lapho kungekho traffic vehicular, ukufaka design ezisindayo futhi enamandla engeke asebenze. Okusanda kubhaklazeka plastic khona, polymers futhi izinto oluyinhlanganisela. Ziyakwazi kulula, eshibhile, babe nesilinganiso ezanele ukuphepha, impilo isevisi eside.

Ngasese izindlu konke ngoba indle amanzi, imishini manholes kanye ukonakala amathangi amapayipi ukusetshenziswa izindandatho sasakhiwe ngokhonkolo nakakhulu. Kulokhu buyafaneleka ukusetha phezu kwabo ngendlela efanayo ukuze dweba. Ikhava nayo ekhiqizwa kusuka ukhonkolo. Kuyinto ubukhulu amakhulu kunalo, kodwa ayiyona ingxenye inkatho, kodwa umane uvala kuvulwa dweba. ukwakhiwa Massive sinzima ngokwanele, ngeke ngephutha ukuhambisa. Linikeza ukuphepha kudingekile ngesikhatsi kokuhlinzwa.

Ukucaciswa kanye kophawu

kubhaklazeka esindayo (isigaba T) isetshenziselwa ukuthuthukisa traffic imithwalo. Bangase babe nesisindo 100 kg kanye ukushuba okungaphezulu kuka 100 mm. Lapho kungekho traffic vehicular inikezwa usebenzisa ukukhanya kubhaklazeka (Ikilasi). Ezakhiwe izingadi, utshani kanye nezinye izindawo (isigaba A) kufanele ububanzi 540 mm kanye ukushuba 50 mm.

Kungani mgodi ihlanganisa round futhi ibhalwe? Lokhu kwenziwa kube lula ukuqashelwa ukuthi leyo mikhaya ikuyiphi kuya ngezidingo. On nezigqoko imyutsya izinhlamvu: GS - igesi inethiwekhi, MG - igesi main GHG - umlilo hydrant, njll
