Uma kukhulunywa ngokwakhiwa kanye nobunjiniyela bomphakathi, ukukhethwa kwempahla kubalulekile ukuze kuqinisekiswe ubuqotho nokuphila isikhathi eside kwesakhiwo. Enye impahla enjalo eye yazuza idumela eliqinile emboniniI-ASTM A252 Ibanga lesi-2AmaPipe Piles. Le bhulogi izocubungula imininingwane, izakhiwo, kanye nezidingo zokumaka ze-ASTM A252 Grade 2 ukuze ithole ukuqonda okuphelele ngokubaluleka kwayo kumaphrojekthi wokwakha.
Iyini i-ASTM A252 Grade 2?
I-ASTM A252 iwukucaciswa okujwayelekile kwezinqwaba zensimbi ezishiselwe nezingenamthungo zokusetshenziswa kwesisekelo. IBanga lesi-2 lingelinye lamabanga amathathu ashiwo kuleli zinga, iBanga loku-1 liphansi kakhulu kanti iBanga lesi-3 liphakeme kakhulu ngokwamandla esivuno. Izinqwaba zamashubhu ze-ASTM A252 zeBanga lesi-2 zenzelwe ukunikeza ibhalansi yamandla kanye ne-ductility, izenze zifanelekele ukusetshenziswa okuhlukahlukene, okuhlanganisa izisekelo ezijulile, izakhiwo zasolwandle, nezinye izimo ezithwala imithwalo.
Izakhiwo ezibalulekile ze-ASTM A252 IBanga lesi-2 zifaka amandla amancane esivuno angama-35,000 psi kanye namandla amancane okudonsa angama-60,000 psi. Lezi zakhiwo ziqinisekisa ukuthi ama-piles angakwazi ukumelana nemithwalo ebalulekile kanye nokucindezeleka, okuwenza alungele ukusetshenziswa ezindaweni eziyinselele.
I-ASTM A252 yeBanga lesi-2 Izidingo Zokumaka Izinqwaba zamapayipi
Isici esibucayi se-ASTM A252 Grade 2 piles siyisidingo sokumakwa okufanele. Inqwaba ngayinye kufanele imakwe ngokucacile ukuze inikeze ulwazi olubalulekile mayelana nomkhiqizo. Lokhu kumakwa kubalulekile ekulandeleleni, ukuqinisekiswa kwekhwalithi, nokuhambisana nezindinganiso zomkhakha. Imininingwane elandelayo kufanele ifakwe ekumaka:
1.Igama lomkhiqizi noma uhlobo: Lokhu kukhomba umkhiqizi wenqwaba, ukuqinisekisa ukuthi umsebenzisi angakwazi ukulandelela umkhiqizo awubuyisele emthonjeni wawo.
2.Inombolo Yokushisa: Inombolo yokushisa iyinkomba ehlukile eyabelwe inqwaba ethile yensimbi. Ivumela umsuka nezici zezinto ezibonakalayo ukuthi zilandelelwe, okubalulekile ekulawuleni ikhwalithi.
3.Inqubo Yomkhiqizi: Lokhu kubonisa indlela esetshenziswa ukukhiqiza inqwaba, kungakhathaliseki ukuthi ishiselwe noma ingenamthungo. Ukuqonda inqubo yokukhiqiza kusiza ekuhloleni izici zokusebenza zenqwaba.
4.Spiral Joint Type: Uhlobo lwejoyinti elivunguzayo elisetshenziswa ku-inqwaba yepayipikufanele imakwe, uma ikhona. Lolu lwazi lubalulekile ekuqondeni ubuqotho besakhiwo senqwaba.
5.Ububanzi Bangaphandle: Ububanzi bangaphandle benqwaba kufanele buphawulwe ngokucacile njengoba buwubukhulu obubalulekile ekubalweni kokufakwa nokulayisha.
I-6.Ukushuba kodonga lwegama: Ukuqina kodonga lwenqwaba kungesinye isilinganiso esibalulekile esithinta amandla ayo kanye namandla okuthwala.
7.Ubude nesisindo ngobude: Ubude obuphelele nesisindo ngobude benqwaba kufanele buchazwe. Lolu lwazi lubalulekile ekuhleleni izinto nokufaka.
8.Igama Elicacisiwe kanye neBanga: Okokugcina, ukumakwa kufanele kufake negama elicacisiwe (ASTM A252) kanye nebanga (iBanga lesi-2) ukuze kuqinisekiswe ukuthotshelwa kwezindinganiso zemboni.
Ekuphetheni
AmaPipe Piles e-ASTM A252 eBanga lesi-2 ayingxenye ebalulekile yokwakha yesimanje, ehlinzeka ngamandla adingekayo kanye nokuqina kwezinhlelo zokusebenza ezihlukahlukene. Ukuqonda izimfuneko zokucaciswa nokumaka kubalulekile konjiniyela, osonkontileka, nabaphathi bephrojekthi ukuze baqinisekise ukuthi basebenzisa izinto ezifanele kumaphrojekthi abo. Ngokunamathela kulawa mazinga, imboni yezokwakha ingagcina izinqubo zekhwalithi ephezulu futhi iqinisekise ukuphepha nokuphila isikhathi eside kwezakhiwo ezakhelwe kulawa malungu esisekelo.
