Ukuhlaziywa Kwezimbobo Zokubhoboza Izinqwaba ze-Precast kanye namapayipi oDrill we-Cast-In-Place Piles -2

Izimo zokwakha

Inqwaba yamapayipi acindezelwe ifanele inhlabathi ethambile, inhlabathi eyisihlabathi, inhlabathi yepulasitiki, inhlabathi enodaka, isihlabathi esihle, kanye nenhlabathi ewugwadule exekethile engenamatshe noma amatshe antantayo. Ayingeni kalula esihlabathini esiwugqinsi nezinye izinhlayiya eziqinile kodwa ingangena kuphela ekujuleni kwesihlabathi, amatshe, ubumba oluqinile, amadwala anesimo esiqinile, nezinye izingqimba eziqinile ezisekelayo. Uma ukunqwabelanisa isihlabathi namatshe kunzima, izimbobo zokuhlola zingasetshenziswa. Lapho ushayela noma ucindezela ngokuqhubekayo inqwaba yepayipi elicindezelwe ngaphambili futhi usebenzisa ungqimba lwedwala oluqine kakhulu njengongqimba olusekelayo lwesisekelo senqwaba, umzimba wenqwaba uzodlula enhlabathini eminingi ebuthakathaka, inhlabathi ehlangene, kanye nongqimba lwamadwala oluqinile. Ngakho-ke ngeke kube nokumelana okukhulu nomzimba wenqwaba. Isibonelo, ukucwiliswa kwendawo kanye nokusatshalaliswa kwamadwala angawodwa kulo lonke idwala eliklanywe ngamatshe kungase kubangele ubunzima obuthile ezinqwabeni. Njengoba ukwakhiwa kudinga imishini emikhulu efana nezando zenqwaba ezinyakazayo nemishini yokuphakamisa, indawo yokwakha edingekayo inkulu uma kuqhathaniswa.

Izinqwaba zamapayipi okusanhlamvu zilungele inhlabathi enesihlabathi, inhlabathi ehlangene, kanye nenhlabathi yamatshe namatshe amatshe, kanye nokwakheka kwamadwala. Nokho, kunzima ukwakha udaka nezisekelo okungenzeka zibe nesihlabathi esigelezayo noma amanzi anomfutho. Ngakho-ke, uma kuqhathaniswa nezinqwaba zamapayipi ezicindezelwe, izinqwaba ezinezithukuthezi zinezici zemishini yokwakha elula, ukusebenza okulula, nokukhululeka emikhawulweni yendawo. Kodwa isikhathi sokwakha side kunezinqwaba zamapayipi ezigxiliwe, futhi ikhwalithi yokwakha ayizinzile.

Ubuchwepheshe bokwakha

Ubuchwepheshe bokwakha inqwaba yamapayipi acindezelwe yilokhu: ukulinganisa nokubeka → ukubekwa nokubeka phakathi nendawo komshini wenqwaba → ukucindezela inqwaba → ukuhlanganisa inqwaba → ukulethwa kwenqwaba noma ukusika → inqwaba yokucindezela okumile ukuze ufinyelele ukuphakama komklamo.

(1) Isilinganiso nokuma: Beka shaft nenqwaba ngayinye ngaphambi kokwakhiwa, futhi upende ukuze wenze uphawu lube sobala.

(2) Ukubekwa nokuqondanisa komshayeli wenqwaba: umshayeli wenqwaba usetshenziselwa ukuqalisa i-theodolite.

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