Umshini we-Static Pressure Caisson
Izici Zokusebenza
Umshini we-caisson ocindezelwe yi-static pressure unamandla okulawula ukunemba okuphezulu kokwakhiwa kanye nokulawula ukuma. Ungaqeda ukungena, ukumba kanye nokuvala phansi ngaphansi kwamanzi komthombo ongamamitha ayi-9 ukujula kungakapheli amahora ayi-12. Ngesikhathi esifanayo, ulawula ukuhlala komhlabathi kungakapheli amasentimitha ama-3 ngokugcina ukuqina kwengqimba yokuthwala. Imishini ingaphinda isebenzise ama-casing ensimbi ukunciphisa izindleko zezinto zokwakha. Ifanele futhi izimo ze-geological ezifana nomhlabathi othambile kanye nomhlabathi onodaka, ukunciphisa ukudlidliza kanye nemiphumela yokucindezelwa kwenhlabathi, futhi ayinawo umthelela omkhulu endaweni ezungezile.
Uma kuqhathaniswa nendlela yendabuko ye-caisson, ayidingi izindlela zokusekela zesikhashana njengezinqwaba ze-jet grouting ezinomfutho ophezulu, ukunciphisa izindleko zesakhiwo sokwakha kanye nokuphazamiseka komhlaba.

Izicelo
Umshini we-caisson ocindezelwe yi-static pressure uwuhlobo lwemishini yokwakha ekhethekile. Usetshenziswa kakhulu ekwakheni imithombo yokusebenza noma ama-caisson kumaphrojekthi angaphansi komhlaba. Ucindezela i-casing yensimbi engqimbeni yomhlabathi ngengcindezi engaguquki, futhi ngesikhathi esifanayo ubambisana nokumba kwangaphakathi ukuze kufezwe ukucwila.
Ukusetshenziswa kwayo okuyinhloko kufaka phakathi: Ngesikhathi sokwakhiwa kwe-caisson, umshini we-caisson wokucindezela okungaguquki uqinisa i-casing yensimbi ngedivayisi egobile bese usebenzisa ingcindezi eqondile, kancane kancane uyifake engqimbeni yomhlabathi. Ifanele ubunjiniyela bomasipala, izisekelo zamabhuloho, izitshalo zokuhlanza indle, izindlela ezingaphansi komhlaba
