Kev soj ntsuam ntawm Drilling qhov rau Precast Piles thiab Drill Pipes rau Cast-In-Pile Piles -1
Raws li kev tsim kho sib txawv, pawg tuaj yeem muab faib ua pawg precast (cov yeeb nkab prestressed) thiab cast-in-place piles (drill-pipe cast-in-place piles). Lawv ob leeg tau siv dav hauv cov hauv paus av mos thiab cov hauv paus tob tob. Lawv muaj cov yam ntxwv ntawm kev muaj peev xwm siab, kev ruaj ntseg zoo, kev sib haum xeeb me me, thiab cov khoom siv tsawg thiab tuaj yeem ua tau raws li lub tsev lub zog, deformation, thiab stability. Ob hom pawg muaj lawv cov yam ntxwv, kev tsim kho sib txawv, cov cuab yeej siv tshuab sib txawv, thiab cov txheej txheem kev tsim kho. Lawv mechanism thiab daim ntawv thov yog txawv. Kab lus no yuav muab piv rau ob hom pawg no thiab txheeb xyuas lawv qhov zoo, qhov tsis zoo, thiab daim ntawv thov los txiav txim siab seb puas yuav xaiv cov yeeb nkab uas muaj zog los yog pawg dhuav.
Prestressed yeeb nkab pawg yog lub hollow yeeb nkab lub cev slender qhob prefabricated tivthaiv ua los ntawm pre-tensioning technology, high-ceev centrifugal chav curing molding txoj kev nrog ntxiv high-efficiency dej txo tus neeg sawv cev. Nws yog tsim los ntawm cov cylindrical pawg lub cev, endplate, thiab steel hoop.
Ib pawg dhuav yog ib pawg ua los ntawm kev khawb ib lub qhov ntawm qhov chaw engineering, khawb ib lub qhov slag qhov twg cov av tau tawg, muab cov hlau thav duab tso rau hauv lub pob qhov, thiab tom qab ntawd nchuav pob zeb rau hauv pawg.
Cov yeeb nkab prestressed thiab boring piles yog muab piv thiab soj ntsuam los ntawm cov kev xav ntawm mechanism, kev tsim kho, kev tsim kho technology, thiab kev tsim kho nqi.
Mechanism
Prestressed yeeb nkab pawg yuav ncav cuag qhov xav tau qhov tob los ntawm kev xyaum cov yeeb nkab siab. Thaum lub sij hawm piling txheej txheem, cov av ib puag ncig ib ncig ntawm pawg neeg yog squeezed tawm, ua rau lub pore dej siab, uplift, thiab lateral compression nyob rau hauv ib tug luv luv lub sij hawm. Hauv av, kev ntxhov siab yuav cuam tshuam rau thaj tsam ntawm cov tsev uas twb muaj lawm, cov ntsiab lus thiab deformation ntawm txoj kev. Nyob rau tib lub sijhawm, nws yuav nyem lub pob zeb ua tiav ua kom nws ntws thiab ntab.
Drilling yeeb nkab boring pawg yog tsim los ntawm cov txheej txheem qhuav los yog av nkos. Thaum lub sij hawm tus txheej txheem ntawm pore tsim thiab pawg tsim, cov nyob ib puag ncig pawg tsis muaj squeezing nyhuv ntawm cov av, thiab yuav tsis ua rau ntau heev pore dej siab nyob rau hauv cov av. Yog li ntawd, kev tsim kho ntawm pawg yuav tsis ua rau muaj kev nyab xeeb ntawm cov tsev nyob ib sab thiab txoj kev. Yog li ntawd, piv nrog prestressed yeeb nkab piles, boring pawg muaj cov yam ntxwv ntawm tsis muaj kev co, tsis muaj compaction nyhuv, thiab tsawg cuam tshuam rau cov vaj tse nyob ib puag ncig. Tab sis cov pob zeb muaj zog thiab cov kabmob muaj peev xwm ntawm pawg pawg yog qis dua thiab qhov kev sib haum xeeb loj dua.
Yog tias koj txaus siab rau tungsten carbide rods thiab xav tau cov ntaub ntawv thiab cov ntsiab lus ntxiv, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa ntawv xa mus rau peb hauv qab ntawm nplooj ntawv.
