VII. Steel ntawv tsav tsheb.
LeeSen steel ntawv txheej txheem pawg tsim muaj feem xyuam rau cov dej nres thiab kev nyab xeeb thaum kev tsim kho. Nws yog ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws hauv txoj haujlwm no. Thaum kev tsim kho, cov kev tsim kho cov kev tsim kho hauv qab no yuav tsum tau sau tseg:
(1) Cov ntawv LowerSen steel piles tau tsav los ntawm crawler pawg tsav tsheb. Ua ntej tsav tsheb, koj yuav tsum paub txog cov xwm txheej ntawm cov raj hauv av thiab cov qauv thiab ua tib zoo tso tawm qhov tseeb ntawm txoj kab ntawm cov nyiaj txhawb nqa.
(2) Ua ntej tsav tsheb, tshawb xyuas txhua daim ntawv hlau pawg thiab tshem cov ntawv hlau pawg uas muaj xeb lossis txo qis ntawm kev sib txuas xauv. Lawv tsuas yog siv tau tom qab lawv raug kho thiab tsim nyog. Cov uas tseem tsis tau txais kev kho tom qab kho tau raug txwv.
(3) Ua ntej tsav tsheb, roj yuav siv tau rau lub xauv ntawm cov ntawv hlau pawg los pab txhawb kev tsav tsheb thiab tshem tawm cov ntawv hlau txheej txheem.
(4) thaum lub sijhawm tsav tsheb ntawm cov ntawv hlau nplooj pawg, txoj kab nqes ntawm txhua pawg yuav tsum tau ntsuas thiab saib xyuas kom tsis pub dhau 2%. Thaum deflection yog loj heev los tau hloov kho los ntawm rub txoj kev, nws yuav tsum rub tawm thiab tsav dua.
(5) Nco ntsoov tias cov ntawv hlau tsis muaj tsawg dua 2 metres tob tom qab kev khawb, thiab xyuas kom lawv tuaj yeem kaw tau yooj yim; Tshwj xeeb, plaub fab ntawm kev tshuaj xyuas kom zoo yuav tsum siv kaum hlau steel ntawv piles. Yog tias tsis muaj cov log hlau xws li, siv cov log tsheb qub lossis cov khoom lag luam los sau cov seams thiab lwm yam kev ntsuas ib qho kom tiv thaiv kom tsis txhob muaj av qeeg.
(6) Txhawm rau tiv thaiv cov av txuas ntxiv los ntawm cov hlau pov tseg, tom qab cov ntawv stainless tau txuas, siv cov ntaub ntawv hlau Ob tog ntawm qhib channel rau tag nrho, txog 1.5m hauv qab pawg saum toj kawg nkaus, thiab weld lawv nrog hluav taws xob vuam rods. Tom qab ntawd, siv hollow round hlau (200 * 12 hli) Txhua 5 metres, thiab siv cov pob qij txha tshwj xeeb los txhawb cov hlau ntawv hlau pawg ntawm ob tog symmetrically. Thaum txhawb nqa, lub txiv ntoo ntawm cov sib luag tau sib koom ua ke yuav tsum tau nruj kom ntseeg tau qhov tseeb ntawm cov ntawv nyeem kab ntsig thiab cov trenen cov txheej txheem ua haujlwm.
(7) thaum lub sij hawm khawb ntawm lub hauv paus trench, saib cov kev hloov pauv ntawm cov ntawv hlau piles txhua lub sijhawm. Yog tias muaj qhov pom tseeb los yog upift, tam sim ntawd ntxiv cov kev txhawb nqa ncaj qha rau qhov ntxeev siab lossis txhawb nqa ntu.
Ⅷ. Kev tshem tawm cov hlau hlau piles
Tom qab lub hauv paus lub zog yog backfilled, cov ntawv steel piles yuav tsum tau muab tshem tawm rau kev rov siv dua. Ua ntej tshem cov ntawv hlau pawg, cov txheej txheem tshem tawm ntawm pawg, pawg tshem tawm thiab kev kho rau cov av yuav tsum tau ua tib zoo kawm. Txwv tsis pub, vim muaj kev co ntawm pawg tshem tawm thiab cov av muaj kev cuam tshuam nrog cov vaj tse uas nyob ib sab ntawm cov tsev, vaj tse lossis cov raj hauv av. Nws yog ib qho tseem ceeb heev uas yuav tau sim txo cov av nqa los ntawm cov piles. Tam sim no, kev ntsuas lub ntsiab siv yog kev txhaj tshuaj dej thiab cov xuab zeb txhaj.
(1) pawg kab sib txawv
Qhov project no tuaj yeem siv Rauj Rauj kom rub cov av thiab rhuav tshem cov av hlau kom kov yeej cov kab mob sib tsoo kom dhau mus rau kev rho tawm ntxiv, thiab cia siab rau kev nqa khoom ntxiv yuam kom tshem lawv.
(2) kev ceev faj thaum rub tawm pawg
a. Pib taw tes thiab ua ntu zus ntawm pawg extraction: rau kaw steel phaj cuam tshuam yuav tsum muaj ntau tshaj 5 deb ntawm lub kaum kaum. Qhov pib taw tes ntawm pawg extraction tuaj yeem txiav txim siab raws li qhov xwm txheej thaum cov piles tau siv tau yog tias tsim nyog. Qhov kev txiav txim ntawm pawg extraction yog qhov zoo tshaj yog kom rov qab mus rau pawg tsav tsheb.
b. Kev co thiab rub tawm: Thaum rub tawm cov pawg, koj tuaj yeem siv lub rauj viber kom txo tau cov nplaum ntawm cov av, thiab tom qab ntawd rub nws tawm thaum vibrating. Rau cov ntawv pawg uas nyuaj rau rub tawm, koj tuaj yeem siv lub rauj siv hluav taws xob ntau, koj tuaj yeem hloov pauv thiab rub tawm nrog lub rauj rauj.
(3) Yog tias cov ntawv hlau sau tsis tuaj yeem rub tawm, cov kev ntsuas hauv qab no tuaj yeem ua:
a. Siv lub rauj rauj kom tsoo nws dua kom kov yeej cov kev tawm tsam nrog cov av thiab xeb ntawm tom;
b. Rub tawm cov piles nyob rau hauv rov qab txiav txim ntawm daim ntawv teev pawg tsav ntu;
c. Cov av nyob ntawm sab ntawm daim ntawv ntawm daim ntawv uas Dais cov av siab av yog denser. Tsav tsheb lwm pawg pawg hauv parallel ze nws tuaj yeem ua tus thawj ntawv pawg rub tawm txoj kev ntseeg nkev;
d. Ua qhov zuaj rau ob sab ntawm cov ntawv sau thiab muab tso rau hauv bentonite slurry kom txo cov pawg.
(4) cov teeb meem sib xws thiab cov kev kho mob hauv cov ntawv hlau txheej txheem:
a. Qaij. Qhov laj thawj rau cov teeb meem no yog qhov kev tawm tsam ntawm pawg tau tsav thiab cov pawg uas nyob ib sab yog qhov loj, thaum lub sij hawm tsav tsheb yog me me; Txoj kev kho mob yog: Siv cov twj paj nruag los tshawb xyuas, tswj thiab kho tau txhua lub sijhawm thaum txoj kev tsim kho; Siv cov hlua hlau kom rub lub cev uas rub tawm thaum tilting tshwm sim, rub thiab tsav tib lub sijhawm, thiab maj mam kho nws; Feserve tsim kev cuam tshuam rau thawj tus neeg tsav daim ntawv pawg.
b. Torsion. Qhov laj thawj rau qhov teeb meem no: lub ntsuas phoo yog qhov kev sib txuas ntawm kev sib txuas; Txoj kev kho mob yog: Xauv cov xauv xub ntiag ntawm daim ntawv teev nrog daim npav hauv kev coj ntawm pawg tsav; Teeb tsa cov nkhaus pulley hauv ob sab ntawm ob daim hlau pawg kom nres qhov kev sib hloov ntawm cov ntawv thaum lub sijhawm tog; Sau ob sab ntawm lub ntsuas phoo ntawm ob daim ntawv uas muaj cov ntaub qhwv thiab cov ntoo ntoo.
c. Co-sib txuas. Qhov laj thawj rau qhov teeb meem: cov ntawv steel pawg pawg yog qaij thiab khoov, uas nce qhov tsis kam ntawm qhov chaw; Txoj kev kho mob yog: kho cov qaij ntawm daim ntawv pawg hauv lub sijhawm; Ib ntus kho cov piles nyob ib ntus uas tau tsav nrog lub kaum ntse ntse.
9. Kev kho cov av qhov hauv cov ntawv hlau pawg
Cov pawg ib lub qhov sab laug tom qab rub tawm cov piles yuav tsum tau ua tiav hauv qab. Cov kab ke nkag mus rau txoj kev puv, thiab cov ntaub ntawv siv hauv txoj kev sib sau yog pob zeb sib xyaw.
Cov saum toj no yog cov ncauj lus qhia ntxaws ntxaws ntawm cov txheej txheem kev tsim kho ntawm Larsen steel ntawv pawg. Koj tuaj yeem xa nws mus rau cov neeg xav tau ib puag ncig koj, them sai sai rau juxiang tshuab, thiab "kawm ntxiv" txhua hnub!
