Ukufakwa Kwe-Press-in Sheet Pile

Ukufakwa kwemaphuzu esikhumbuzo asebenza ngocingo kukhonjiswa njengenqubo yokuthutha ethuthukisiwe yokufaka amaphuzu esikhumbuzo emhlabathini ngaphandle kokwenza umonakalo omkhulu noma umsindo, okwenza kube ubuchwepheshe obubalulekile ekwakhiweni kwemiphambili ejulile lapho izithiyo zemvelo, ububanzi bendlela, noma izimo zomhlaba ezinzima zidinga ukufakwa ngokunembile. Ngokwehlukana nezinqubo zokusebenza noma zokuvibrayo, ubuchwepheshe bokufaka buphakathi bokusebenzisa ing压力 elawulwayo ebhayisikobho ehlanganiswe nokusebenza okwenziwe ngokuvumelana ukuze kuthuthuke amaphuzu ngama-scale, kunika ukulawulwa okungcono kokufanisa, ukuthuthuka, kanye nokudlulela kwahlukeneyo phakathi nesikhathi sokufakwa. Izinhlelo zokufaka amaphuzu esikhumbuzo zisetshenziswa ezinhlelweni ezahlukahlukene kufaka phakathi udonga lwezikhumbuzo ezithungiwe nezithuthi ukuhlinzeka ngokunqwabelana nokufaka ama-cofferdams, ama-curtain anqanda imvelo nokulawulwa kokungcolisa, kanye nokwakhiwa kwamadwala e-diaphragm ezindaweni eziyinqaba lapho izithiyo zomculo nemisindo kufanele zilandelwe. Le teknoloji ibaluleke kakhulu ezimweni zomhlaba ezinekhono lokuphakanyiswa, ukufakwa okunamafutha, noma izindawo zomhlaba-nkanyezi lapho izindlela zokuvibrayo noma ezithungiweyo zikhola umonakalo omkhulu ngokuphana noma zikhuphule izinga lokufaka ngaphandle kokulawula, ngaleyo ndlela kuncishiswe ukulungiswa kokuphawula noma kudaleke umonakalo emsebenzini ongakhelwe ngaphezulu. Iziphuzo ezisebenzayo ziqhamuka nesistimu yokuphakamisa ye-hydraulic enamandla ethatha ing压力 elawulwayo—ngokuvamile 50–500 tone ngamaphuzu kuye ngekhono lemishini—nenketho yokusebenza evumelanisiwe yokwakha okungaphansi (12–18 Hz) ukuze kuncishiswe ukucwenga komhlaba futhi kube khona ukuvuselela. I-rig yokufaka i-ankhula kumaphuzu akhona noma kumaframu okuhlola, ibamba isigaba samaphuzu sikhathi esikhona ngendlela yokusebenza, futhi ithuthuke kancane kancane ngesikhathi ifaka ubukhulu be-load, ukunyakaza, nokugxila ngokuqhubekayo ngokusebenzisa ama-sensors ahlanganisiwe. Uma isigaba samaphuzu sifinyelela ekuqedeni, isigaba esilandelayo siqondiswa, sithungwa, futhi sifakwa ngempela. Le nqubo elawulwayo ivumela abashayeli ukuthi bagcine izilinganiso ezinqala zendawo yomqondo nokunyakaza, babe stopped ezindaweni ezithile, noma baphume amaphuzu ngokuphelele ukuze kusebenze okwesikhashana. Izinhlaka zemishini kule nsimu zihlanganisa ama-vibratory pile presses ahlanganisa ing压力 elawulwayo nokulungiswa kwamafrequencies alawulwayo, amasistimu aphezulu e-hydraulic press ukuhlola umhlaba osebenzayo noma obunzima, ama-reaction beam assemblies kanye namaphuzu ahlanganisa ukuqinisa i-rig, ama-clamps akhethekile uzakhamuzi akhiwe ukuze ahambisane nezinhlobo zephezu, kanye nemishini yokukhipha ephathwe kalula yokufakwa okwesikhashana. Izinhlelo zesimanje zihlanganisa ama-load cells, ama-inclinometers, kanye nezinhlelo zokubhalela ezizenzakalelayo ezinikeza ukuqinisekiswa okuqhubekayo kwedatha yokufaka kanye nezincwadi zokuqinisekisa. Izinqumo zokukhetha zifaka izibonakaliso zomhlaba (ukuphakanyiswa okungathwelekile, i-angles yokuhlangana, ukumelana nokufakwa kwe-cone), ububanzi bokufaka obufunwa, izinga lokuqedela isikhombisa kanye nezinyathelo zomthetho, imingcele emisha nemisindo (ngokuvamile 75–85 dB ezindaweni ezithile), isikhala esitholakalayo sokwakha i-rig, ukuguquguquka kokuhlanganiswa komhlaba, ukungena kwemikhawulo noma amasimu, izidingo zokukhiqiza, kanye nokuthi amaphuzu ayizinto ezihlala njalo noma ezikwenza kanye. Izindinganiso ezifanele zifaka phakathi i-EN 12699 (imishini yokufaka amaphuzu esikhumbuzo ngokusebenzisa ukubhalisa), i-EN 1997-1 (u-Eurocode 7—ukwakhiwa kwezobuchwepheshe), i-DIN 4014 (izindonga zamaphuzu esikhumbuzo), kanye ne-API RP 2A (izimiso zokwakhiwa). Lezi zindinganiso zakha izidingo zokuhanjiswa kwemishini, uqinisekiso lwezinqubo, izinhlelo zokuphathwa kwekhwalithi, nezincwadi zokufakwa ukuze kuqinisekiswe ubuqotho bokwakhiwa kanye nokusebenza okubuyisayo ngaphansi kokuhlangana kokwakhiwa.
