Isexwayiso Esibalulekile: Lona umbhalo wengobo yomlando womlando, hhayi ukucaciswa komshini wamanje, ukubala umthamo, ukuhlola ubungozi noma imanuwali yokusebenza. Izindlela zokuqinisa, amamodeli, ubukhulu, isivinini, amafomula, abahloli nezinqubo kufanele zihlolwe ngokuya ngemithetho esebenzayo, imibhalo yomkhiqizi kanye nemithetho ephephile yokusebenza.
Lo mbhalo awukona ukunikezwa kwemishini, izihloli noma amadokhumenti esevisi ye-Savo Kusić. Okunikezwayo kwamanje kugxile kumafasitela, iminyango nezixazululo ezihambisanayo.
Ukuqinisa isaha kuhlaka
Ngama-gutters, amasaha kufanele avikelwe kahle futhi aqinise kuhlaka. Lapho usebenza ngamasaha ane-tensioned weak, shard ngendlela ye-wavy cut, njll. Indlela ejwayeleke kakhulu yokuqinisa isaha usebenzisa i-wedge, i-eccentric, isikulufu (Fig1), kanye nendlela yokuqinisa usebenzisa amadivaysi e-hydraulic. Ukuqinisa isaha ngama-wedges kubi kunezinye izindlela. Inani elikhulu lezimboni likhiqiza inani elikhulu lezinhlobo zamasaha anamandla, ahamba ngokushesha, akhiqiza kakhulu. Lawa masaha akhiqiza kakhulu asebenza ezimbonini ezinkulu zokucubungula izinkuni embonini yezokwakha. Izici zobuchwepheshe zalawa ma-gaiters anikezwe etafuleni1.

Ukukhiqiza kwe-Gator kubalwa ngokuya ngefomula: P = K - Δtnq/1000L m3. Lapho u-K kuyi-coefficient yokusetshenziswa kwesango. Okwezintambo zikamshini K = 0.93, kanye nalezo ezinomshini omncane K = 0.90; Δ - ukususwa endaweni eyodwa kwe-shaft yesango; n - inombolo yezinguquko ze-shaft yesango ngomzuzu; t - isikhathi sokusebenza kwesango ngemizuzu; q - ivolumu yelogi, m3; L - ubude bezingodo, m.
Ukubalwa ngokomlando kokukhiqiza
Uma kunqunywa isilinganiso sonyaka sokukhiqiza kwesango leshifu eyodwa, ukumiswa, okwenzeka ngenxa yezizathu ezihlukahlukene (ukulungiswa, ukuntuleka kwezinto zokusetshenziswa, njll.) kufanele kucatshangelwe. Lokhu kulahlekelwa kunqunywa i-coefficient yokuhlola u-Kgod = 0.9 - 0.92.
Ngakho-ke, isilinganiso sonyaka sokukhiqiza somgcinisango weshifu eyodwa sinqunywa ifomula ethi P = Kgod x K x Δntq/1000L m3 yeshifu eyodwa.
Izici zobuchwepheshe zamasaha esango zinikezwe kuthebula 3.

Amasaha enziwa ngamaphrofayili amazinyo amabili: anonqenqema lwangemuva oluphukile futhi anomphetho oqondile wangemuva (isib.2). Uma ukhetha ubukhulu obufunayo be-saw, kufanele uqondiswe ubude befreyimu yesango, ubukhulu bokushaywa kwayo kanye nobubanzi bezingodo ezizonqunywa. Ubude obudingekayo besaha bunganqunywa ifomula L = Dmax + H + (300ku350) mm, lapho L kuwubude besaha, mm; I-Dmax - ububanzi obukhulu bezingodo okufanele zinqunywe;300-350- isibonelelo ngenxa yokufakwa kwamabhodi nama-battens; H - ukuphakama kwe-stroke, mm.

Ubukhulu besaha kanye nephimbo lamazinyo kufanele kuhambisane nobude bokusikwa kanye nohlobo lokusikwa. Lobu budlelwano bokuzwana bunikezwe etafuleni4.

Amasaha afakwa kanye nama-stirrps anamathela engxenyeni engezansi yesaha kanye nesethi yama-stitrups amabili namabhawodi ayisikhombisa engxenyeni engenhla. Ama-stirrups ahlanganiswe nesaha ema-engeli angakwesokudla emaphethelweni ayo angemuva. Imiphetho egobile ye-stirrup kufanele ibhekane. Ngaphambi kokuhlehlisa i-stirrup, imiphetho yesaha kufanele ibhekwe ukuze kubonakale ukuthi iqondile futhi ihambisana yini, futhi uma ingahambisani, kufanele isikwe ngomshini wokulola isaha.
