Analysis of Hole Holes for Precast Piles and Drill Pipes for Cast-In-Place Piles -1

Ho ea ka mekhoa e fapaneng ea kaho, liqubu li ka aroloa ka liqubu tsa precast (liphaephe tsa prestressed) le liqubu tse lahliloeng (li-drill-pipe cast-in-place qubus). Ka bobeli li sebelisoa haholo metheong e bonolo ea mobu le metheo e tebileng e epetsoeng. Ba na le litšoaneleho tsa bokhoni bo phahameng ba ho jara, botsitso bo botle, libaka tsa bolulo tse nyane, le tšebeliso e tlase ea thepa 'me li ka kopana ka katleho le matla a moaho, deformation le botsitso. Mefuta e 'meli ea liqubu e na le litšobotsi tsa eona, mekhoa e fapaneng ea kaho, lisebelisoa tse fapaneng tsa mochini, le mekhoa ea kaho. Mochine oa bona le ts'ebeliso ea bona li khetholloa. Sengoliloeng sena se tla bapisa mefuta ena e 'meli ea liqubu le ho sekaseka melemo, mefokolo, le ts'ebeliso ea tsona ho fumana hore na u ka khetha liphaephe tse hahelletsoeng kapa liqubu tse borehileng.

Prestressed pipe pile ke sekoti se nang le 'mele o mosesaane oa konkreite o entsoeng ka theknoloji ea pele ho tsitsipano, mokhoa o phahameng oa lebelo la centrifugal mouoane oa ho folisa ka ho eketsa mokhoa o phahameng oa ho fokotsa metsi. Haholo-holo e entsoe ka 'mele oa cylindrical qubu, endplate, le tšepe hoop.

qubu e borehileng ke qubu e entsoeng ka ho phunya sekoti sebakeng sa boenjiniere, ho cheka sekoti sa slag moo mobu o robehileng, ho beha foreimi ea tšepe ka mokoting oa qubu, ebe o tšela konkreite ka har'a qubu.

Liphaephe tse hatelitsoeng esale pele le liqubu tse borehileng li bapisoa le ho hlahlojoa ho latela litebello tsa mochini, maemo a kaho, theknoloji ea kaho le litšenyehelo tsa kaho.

Mokhoa

Liphaephe tse hatelitsoeng pele li ka fihla botebong bo hlokahalang ka khatello ea lipeipi tsa ho phunya. Nakong ea ts'ebetso ea ho bokella, mobu o pota-potileng 'mele oa qubu oa hatelloa, o baka khatello ea metsi a pore, ho phahamisa le ho hatella ka mahlakoreng ka nako e khutšoanyane. Mobu, khatello ea maikutlo e tla ama boholo ba mehaho e teng, litaba le ho senyeha ha litsela. Ka nako e ts'oanang, e tla petetsa qubu ea kaho e phethiloeng ho etsa hore e hoholehe le ho phaphamala.

Liphaephe tsa ho cheka liphaephe tse boretsoeng li entsoe ka mokhoa o omileng kapa oa ho boloka seretse. Nakong ea ts'ebetso ea pore le ho etsoa ha qubu, liqubu tse potolohileng ha li na phello ea ho penya mobung, 'me li ke ke tsa baka khatello e feteletseng ea metsi a pore mobung. Ka hona, ho hahoa ha liqubu ho ke ke ha beha tšireletseho ea mehaho le litsela tse haufi le eona. Ka hona, ha li bapisoa le liphaephe tse hatelletsoeng pele, liphaephe tse boreleli li na le litšobotsi tsa ho se thothomele, ha ho na phello ea compaction, le tšusumetso e fokolang mehahong e potolohileng. Empa matla a konkreite le matla a ho jara a 'mele oa qubu a tlase' me ho rarolla ho hoholoanyane.
