Ukuhlaziywa Kwezimbobo Zokubhoboza Izinqwaba ze-Precast kanye namapayipi oDrill we-Cast-In-Place Piles -1

Ngokwezindlela ezahlukene zokwakha, izinqwaba zingahlukaniswa zibe yinqwaba ye-precast (inqwaba yamapayipi ane-prestressed) kanye nenqwaba yendawo (i-drill-pipe cast-in-place piles). Zombili zisetshenziswa kakhulu ezisekelweni zenhlabathi ethambile kanye nezisekelo ezingcwatshwe ngokujulile. Banezici zomthamo omkhulu wokuthwala, ukuzinza okuhle, izindawo zokuhlala ezincane, kanye nokusetshenziswa okuphansi kwezinto ezibonakalayo futhi zingahlangabezana ngokuphumelelayo namandla, ukuguqulwa, nokuzinza kwesakhiwo. Lezi zinhlobo ezimbili zezinqwaba zinezici zazo, izindlela ezahlukene zokwakha, imishini ehlukene, kanye namasu okwakha. Indlela yabo kanye nokusetshenziswa kwayo kuyahlukaniswa. Lesi sihloko sizoqhathanisa lezi zinhlobo ezimbili zezinqwaba futhi sihlaziye izinzuzo, ukungalungi, kanye nesicelo sazo ukuze sinqume ukuthi singakhetha yini izinqwaba zamapayipi ane-prestressed noma inqwaba enesizungu.

Inqwaba yamapayipi agxilile iyipayipi elingenalutho eliwumzimba omncane ozacile kakhonkolo owenziwe ngobuchwepheshe be-pre-tensioning, indlela yokubumba enesivinini esiphezulu se-centrifugal yesitimu esihlanganisa nokwengeza i-ejenti yokunciphisa amanzi esebenza kahle kakhulu. Ikakhulukazi yakhiwe ngomzimba wenqwaba eyi-cylindrical, i-endplate, ne-hoop yensimbi.

Inqwaba enesithukuthezi inqwaba eyenziwe ngokubhoboza umgodi endaweni yobunjiniyela, ukumba umgodi we-slag lapho kuphukile khona inhlabathi, ukubeka uhlaka lwensimbi emgodini wenqwaba, bese uthela ukhonkolo enqwabeni.

Izinqwaba zamapayipi acindezelwe kanye nezinqwaba ezibhokile ziqhathaniswa futhi zihlaziywe ngombono wemishini, izimo zokwakha, ubuchwepheshe bokwakha, kanye nezindleko zokwakha.

Indlela

Izinqwaba zamapayipi acindezelwe zingafinyelela ukujula okudingekayo ngokucindezela kwepayipi lokubhoboza. Phakathi nenqubo yokunqwabelanisa, inhlabathi ezungezile ezungeza umzimba wenqwaba iyakhanywa, ibangele umfutho wamanzi ezimbotshana, ukuphakamisa, nokucindezelwa kwezinhlangothi ngesikhathi esifushane. Emhlabathini, ukucindezeleka kuzothinta ububanzi bezakhiwo ezikhona, okuqukethwe kanye nokuguqulwa kwemigwaqo. Ngesikhathi esifanayo, izokhama inqwaba yokwakha eqediwe ukuze iyenze intante futhi intante.

Ipayipi lokubhoboza izinqwaba ezibhodwe zenziwa ngendlela yokugcina udaka eyomile noma. Ngesikhathi senqubo yokubunjwa kwama-pore kanye nokwakheka kwenqwaba, izinqwaba ezizungezile azinawo umphumela wokukhama emhlabathini, futhi ngeke zibangele ukucindezela kwamanzi amboza kakhulu emhlabathini. Ngakho-ke, ukwakhiwa kwezinqwaba ngeke kubeke engozini ukuphepha kwezakhiwo eziseduze nemigwaqo. Ngakho-ke, uma kuqhathaniswa nezinqwaba zamapayipi acindezelwe, izinqwaba ezinesithukuthezi zinezici zokungadlidlizi, azinawo umthelela wokuhlangana, kanye nomthelela omncane ezakhiweni ezizungezile. Kodwa amandla okukhonkolo kanye namandla okuthwala umzimba wenqwaba aphansi futhi ukuhlaliswa kukhulu.

Uma unentshisekelo kuma-tungsten carbide rod futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
