Daim ntawv thov
Kev ua haujlwm, qhov tsos thiab qhov muaj txiaj ntsig zoo yog cov qauv uas tib neeg siv thaum xaiv cov khoom siv hauv tsev niaj hnub no.Cov ntaub ntawv steel yog nyob rau hauv txoj kab nrog peb cov ntsiab lus saum toj no: cov ntsiab lus ntawm nws cov khoom tsim tau muab cov qauv yooj yim thiab siv tau, ua tau raws li tag nrho cov kev xav tau ntawm cov qauv kev nyab xeeb thiab kev tiv thaiv ib puag ncig, thiab cov tsev ua tiav los ntawm steel phaj pawg muaj kev nyiam zoo.
Daim ntawv thov ntawm cov ntawv steel piles khiav los ntawm thiab txuas mus rau tag nrho kev tsim kho kev lag luam, los ntawm kev siv cov tsoos dej conservancy engineering thiab civil technology, nrog rau daim ntawv thov ntawm railway thiab tramway mus rau daim ntawv thov ntawm ib puag ncig muaj kuab paug.
Tus nqi tsim nyog ntawm cov ntawv steel pawg tau raug cuam tshuam los ntawm kev tsim khoom tshiab ntawm ntau yam khoom tshiab, xws li: qee qhov tshwj xeeb welded vaj tse;Hlau phaj ua los ntawm hydraulic vibratory pawg tsav tsheb;Sealed sluice thiab Hoobkas xim kho.Ntau yam ua kom ntseeg tau tias cov ntawv steel pawg tswj hwm ib qho tseem ceeb tshaj plaws tsim cov ntsiab lus, uas yog, nws tsis yog tsuas yog ua rau kev ua tau zoo ntawm cov hlau zoo, tab sis kuj muaj txiaj ntsig rau kev tshawb fawb thiab kev loj hlob ntawm cov ntawv steel pawg lag luam;Nws yog qhov tsim nyog rau kev tsim kho kom zoo dua ntawm cov khoom lag luam kom tau raws li qhov xav tau ntawm cov neeg siv khoom.
Kev txhim kho tshwj xeeb sealing thiab overprinting tshuab yog ib qho piv txwv zoo ntawm qhov no.Piv txwv li, HOESCH patent system tau qhib qhov chaw tseem ceeb tshiab ntawm cov ntawv hlau hauv kev tswj cov pa phem.
Txij li thaum HOESCH steel ntawv pawg tau siv los ua cov phab ntsa ntsug kaw hauv xyoo 1986 los tiv thaiv cov av tsis huv, nws tau pom tias cov ntawv hlau ua tau raws li txhua qhov yuav tsum tau ua los tiv thaiv cov dej xau thiab cov pa phem.Qhov zoo ntawm steel ntawv pawg raws li khaws cov phab ntsa yog maj mam siv nyob rau hauv lwm yam teb.
Cov hauv qab no yog qee qhov ua tau zoo dua geotechnical engineering thiab daim ntawv thov ib puag ncig rau kev siv cov ntawv steel piles:
* Coferdam
* Dej nyab kev hloov pauv thiab tswj
* Kev kho dej qhov system laj kab
* Kev tswj dej nyab
* Cov ntaub ntawv

* Kev tsim kho tuaj yeem nqa tawm ntawm lub nkoj yam tsis tau npaj lwm qhov chaw
Kev tsim kho
Npaj
1.Kev npaj kev tsim kho: ua ntej tsav tsheb pawg, qhov thais ntawm lub taub hau yuav tsum muab kaw kom tsis txhob muaj av squeezing, thiab lub qhov ncauj xauv yuav tsum tau coated nrog butter lossis lwm cov roj.Rau cov ntawv hlau uas tau tawm ntawm kev kho lub sijhawm ntev, deformed xauv lub qhov ncauj thiab xeb hnyav, lawv yuav tsum tau kho thiab kho.Rau khoov thiab deformed pawg, lawv tuaj yeem kho los ntawm hydraulic jacking lossis hluav taws ziab.
2.Division ntawm pawg tsav tsheb khiav seem.
3.Thaum tsav tsheb.Los xyuas kom meej qhov verticality ntawm steel ntawv pawg.Siv ob lub theodolite los tswj hauv ob qho kev qhia.
4.Txoj hauj lwm thiab kev taw qhia ntawm thawj thiab thib ob steel ntawv pawg yuav tsum tau tsav kom raug, thiaj li ua si lub luag hauj lwm ntawm kev taw qhia template.Yog li ntawd, kev ntsuas yuav tsum tau ua ib zaug txhua 1m ntawm kev tsav tsheb, thiab lub zog los yog steel phaj yuav tsum tau welded nrog purlin kev them nyiaj yug rau ib ntus fixation tam sim ntawd tom qab tsav tsheb mus rau qhov predetermined qhov tob.
Tsim
1. Xaiv txoj kev tsav tsheb
Cov txheej txheem kev tsim kho ntawm cov ntawv hlau phaj yog txoj kev tsav tsheb sib cais, uas pib los ntawm ib lub ces kaum ntawm cov ntawv phab ntsa thiab tau tsav ib qho los ntawm ib qho (los yog ob qho hauv ib pab pawg) kom txog thaum kawg ntawm qhov project.Nws qhov zoo yog kev tsim kho yooj yim thiab nrawm thiab tsis tas yuav muaj lwm yam kev txhawb nqa.Nws qhov tsis zoo yog tias nws yooj yim rau tilt daim ntawv pawg mus rau ib sab, thiab nws yog qhov nyuaj los kho tom qab kev ua yuam kev.Yog li ntawd, txoj kev tsav tsheb sib cais tsuas yog siv tau rau cov ntaub ntawv uas qhov yuav tsum tau muaj ntawm daim ntawv pawg phab ntsa tsis siab thiab qhov ntev ntawm cov ntawv pawg me me (xws li tsawg dua 10 m).
2.Txoj kev tsav tsheb ntawm lub vijtsam yog ntxig 10-20 steel ntawv pawg rau hauv cov kab lus qhia hauv kab, thiab tom qab ntawd tsav lawv hauv cov khoom siv.Thaum lub sij hawm tsav tsheb, cov steel ntawv pawg ntawm ob qho kawg ntawm lub vijtsam phab ntsa yuav tsum tau tsav mus rau qhov siab tsim los yog qhov tob kom ua cov ntawv teev cov pawg, thiab tom qab ntawd tau tsav nyob rau hauv nruab nrab ntawm cov kauj ruam ntawm 1/3 thiab 1/2 daim ntawv qhov siab. .Qhov zoo ntawm txoj kev tsav tsheb ntawm lub vijtsam yog: nws tuaj yeem txo qhov cuam tshuam ntawm inclination yuam kev, tiv thaiv ntau dhau inclination, thiab nws yog qhov yooj yim kom ua tiav kaw thiab xyuas kom muaj kev tsim kho zoo ntawm cov ntawv phab ntsa.Qhov tsis zoo yog tias qhov siab ntawm tus kheej sawv ntawm cov pawg ntxig yog qhov siab, thiab kev saib xyuas yuav tsum tau them rau kev ruaj ntseg thiab kev tsim kho kev nyab xeeb ntawm pawg ntxig.
3.Kev tsav tsheb ntawm cov ntawv steel.
Thaum lub sij hawm tsav pawg, txoj hauj lwm tsav tsheb thiab kev taw qhia ntawm thawj thiab thib ob steel phaj pawg yuav tsum tau tsav kom raug.Nws tuaj yeem ua lub luag haujlwm ntawm template kev taw qhia.Feem ntau, nws yuav tsum tau ntsuas ib zaug txhua 1m tsav.Kev tsim kho ntawm kaum thiab kaw cov ntawv steel pawg tuaj yeem txais cov ntawv tshwj xeeb-puab pawg, txoj kev sib txuas, txoj kev sib tshooj thiab txoj kev hloov axis.Txhawm rau kom muaj kev nyab xeeb kev tsim kho, nws yuav tsum tau saib xyuas thiab tiv thaiv cov kav dej tseem ceeb thiab cov kab hluav taws xob siab nyob rau hauv qhov kev ua haujlwm.
4.Kev tshem tawm cov kab ntawv steel.
Thaum backfilling lub hauv paus hauv paus, cov ntawv hlau yuav tsum tau rub tawm kom rov siv dua tom qab ua tiav.Ua ntej rho tawm, cov txheej txheem rho tawm, lub sijhawm rho tawm thiab cov txheej txheem kev kho ntawm cov ntawv hlau yuav tsum tau kawm.Txhawm rau kom kov yeej qhov kev tiv thaiv ntawm cov ntawv pawg, raws li pawg rub cov tshuab siv, cov txheej txheem rub tawm muaj xws li pawg rub tawm, kev co pawg rub thiab cuam tshuam pawg rub.Thaum lub sijhawm ua haujlwm tshem tawm, ua tib zoo saib xyuas thiab tiv thaiv cov kav dej tseem ceeb thiab cov kab hluav taws xob siab nyob rau hauv qhov kev ua haujlwm.[1]
Khoom siv
1.Impact piling machinery: dawb lub caij nplooj zeeg rauj, chav rauj, cua rauj, hydraulic rauj, diesel rauj, thiab lwm yam.
2.Vibratory pawg tsav tsheb tshuab: Cov tshuab no tuaj yeem siv rau ob qho tib si tsav tsheb thiab rub pawg, thiab feem ntau siv yog cov vibratory pawg tsav tsheb thiab rub rauj.
3.Kev vibration thiab cuam tshuam pawg tsav tsheb: lub tshuab zoo li no tau nruab nrog cov txheej txheem cuam tshuam ntawm lub cev ntawm cov tsav tsheb vibration thiab cov clamp.Thaum lub vibration exciter generates nce thiab nqis vibration, nws ua rau muaj kev cuam tshuam quab yuam, uas zoo heev txhim kho kev tsim kho efficiency.
4.Static pawg tsav tsheb tshuab: nias daim ntawv pawg rau hauv av los ntawm lub zog zoo li qub.
