VII. Steel ncej pawg tsav tsheb.
Larsen steel sheet pile kev tsim kho yog cuam tshuam nrog dej nres thiab kev nyab xeeb thaum tsim kho. Nws yog ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws hauv qhov project no. Thaum lub sij hawm tsim kho, cov kev tsim kho hauv qab no yuav tsum tau sau tseg:
(1) Larsen steel ntawv pawg yog tsav los ntawm cov neeg tsav tsheb pawg neeg tsav tsheb. Ua ntej tsav tsheb, koj yuav tsum paub txog cov xwm txheej ntawm cov kav dej hauv av thiab cov qauv thiab ua tib zoo nteg tawm cov kab nruab nrab ntawm cov pawg txhawb nqa.
(2) Ua ntej tsav tsheb, xyuas txhua daim ntawv hlau thiab tshem tawm cov ntawv hlau uas muaj xeb lossis deformed hnyav ntawm qhov kev sib txuas xauv. Lawv tsuas yog siv tau tom qab lawv kho thiab tsim nyog. Cov uas tseem tsis tsim nyog tom qab kho yog txwv tsis pub.
(3) Ua ntej tsav tsheb, roj tuaj yeem siv rau qhov ntsuas phoo ntawm cov ntawv hlau los pab txhawb kev tsav tsheb thiab tshem tawm cov ntawv hlau.
(4) Thaum lub sij hawm tsav tsheb ntawm cov hlau ntawv pawg, txoj kab nqes ntawm txhua pawg yuav tsum tau ntsuas thiab xyuas kom tsis pub ntau tshaj 2%. Thaum lub deflection loj dhau los hloov kho los ntawm txoj kev rub, nws yuav tsum tau rub tawm thiab tsav dua.
(5) Nco ntsoov tias cov ntawv hlau tsis pub tsawg dua 2 meters tob tom qab khawb, thiab xyuas kom meej tias lawv tuaj yeem raug kaw kom du; tshwj xeeb, plaub lub ces kaum ntawm qhov kev tshuaj xyuas zoo yuav tsum siv cov ces kaum steel ntawv pawg. Yog tias tsis muaj cov ntawv hlau zoo li no, siv cov log tsheb qub los yog cov ntaub pua plag los sau cov seams thiab lwm yam kev pabcuam kom muab khi zoo kom tsis txhob xau thiab xuab zeb los ntawm kev ua rau hauv av tawg.
(6) Txhawm rau tiv thaiv cov av sab nraud los ntawm kev nyem cov ntawv hlau hauv qab tom qab kev khawb av, tom qab cov ntawv hlau tau tsav, siv H200 * 200 * 11 * 19mm I-beams los txuas rau Larsen steel ntawv pawg. ob sab ntawm lub channel qhib rau hauv ib qho tag nrho, txog 1.5m hauv qab pawg saum toj kawg nkaus, thiab txuas lawv nrog hluav taws xob vuam rods. Tom qab ntawd, siv hollow round steel (200 * 12mm) txhua 5 meters, thiab siv cov pob qij txha tshwj xeeb txav los txhawb cov ntawv hlau ntawm ob sab symmetrically. Thaum txhawb nqa, cov txiv ntoo ntawm cov pob qij txha txav tau yuav tsum tau nruj kom ntseeg tau qhov tseeb ntawm Larsen steel ntawv pawg thiab cov trench excavation ua hauj lwm nto.
(7) Thaum lub sij hawm excavation ntawm lub hauv paus trench, saib cov kev hloov ntawm cov hlau ntawv pawg nyob rau txhua lub sij hawm. Yog hais tias muaj qhov pom tseeb overturning los yog uplift, tam sim ntawd ntxiv symmetrical kev them nyiaj yug rau lub overturned los yog uplifted qhov chaw.
Ⅷ. Tshem tawm cov ntawv steel
Tom qab lub hauv paus pit yog backfilled, cov ntawv hlau yuav tsum tau muab tshem tawm kom rov siv dua. Ua ntej tshem tawm cov ntawv hlau, cov txheej txheem ntawm kev tshem tawm pawg, lub sij hawm tshem tawm pawg thiab kev kho av yuav tsum ua tib zoo kawm. Txwv tsis pub, vim qhov kev co ntawm pawg tshem tawm thiab cov av ntau dhau nqa los ntawm pawg, hauv av yuav tog thiab hloov pauv, uas yuav ua rau muaj kev puas tsuaj rau cov qauv hauv av uas tau tsim thiab cuam tshuam rau kev nyab xeeb ntawm cov vaj tse nyob ib sab, cov tsev lossis cov kav dej hauv av. Nws yog ib qho tseem ceeb heev uas yuav tau sim txo cov av nqa los ntawm pawg. Tam sim no, cov kev ntsuas tseem ceeb uas siv yog dej txhaj tshuaj thiab xuab zeb txhaj tshuaj.
(1) Pile extraction method
Qhov project no tuaj yeem siv lub vibrating rauj rub pawg: siv lub zog quab yuam tsim los ntawm lub vibrating rauj los cuam tshuam cov av thiab rhuav tshem cov cohesion ntawm cov av nyob ib ncig ntawm cov hlau ntawv pawg kom kov yeej qhov tsis kam mus rau pawg extraction, thiab cia siab rau kev txhawb nqa ntxiv. yuam kom tshem tawm lawv.
(2) Kev ceev faj thaum rub pawg
ib. Pib taw tes thiab ua ntu zus ntawm pawg rho tawm: Rau qhov kaw steel phaj cuam tshuam phab ntsa, qhov pib ntawm pawg rho tawm yuav tsum yog ntau tshaj 5 deb ntawm lub ces kaum pawg. Lub ntsiab lus pib ntawm pawg rho tawm tuaj yeem txiav txim siab raws li qhov xwm txheej thaum pawg tau poob, thiab txoj kev dhia rho tawm tuaj yeem siv yog tias tsim nyog. Qhov kev txiav txim ntawm pawg rho tawm yog qhov zoo tshaj plaws los ua qhov sib txawv ntawm pawg tsav tsheb.
b. Kev vibration thiab rub tawm: Thaum rub tawm cov pawg, koj tuaj yeem ua ntej siv lub vibrating rauj kom vibrate lub xauv qhov kawg ntawm daim ntawv pawg kom txo cov adhesion ntawm cov av, thiab ces rub tawm thaum vibrating. Rau cov ntawv pawg uas nyuaj rau rub tawm, koj tuaj yeem ua ntej siv lub tshuab hluav taws xob kom vibrate pawg cia li 100 ~ 300mm, thiab tom qab ntawd hloov vibrate thiab rub tawm nrog rauj vibrating.
(3) Yog tias cov ntawv hlau tsis tuaj yeem rub tawm, cov kev ntsuas hauv qab no tuaj yeem ua tau:
ib. Siv lub vibrating rauj los tsoo nws dua los kov yeej qhov kev tawm tsam los ntawm kev sib txuas nrog cov av thiab xeb ntawm qhov tom;
b. Rub tawm cov pawg nyob rau hauv qhov kev txiav txim ntawm cov ntawv pawg tsav tsheb sib lawv liag;
c. Cov av nyob rau sab ntawm daim ntawv pawg uas bears cov av siab yog denser. Tsav lwm daim ntawv pawg nyob rau hauv parallel nyob ze nws yuav ua rau cov thawj daim ntawv pawg rub tawm smoothly;
d. Ua grooves ntawm ob sab ntawm daim ntawv pawg thiab muab tso rau hauv bentonite slurry kom txo tau qhov tsis kam thaum rub tawm pawg.
(4) Cov teeb meem tshwm sim thiab txoj kev kho mob hauv kev tsim kho steel phaj:
ib. Tilt. Yog vim li cas rau qhov teeb meem no yog tias qhov kev tawm tsam ntawm pawg tau tsav thiab cov pawg uas nyob ib sab yog qhov loj, thaum qhov kev nkag mus rau hauv cov kev taw qhia ntawm pawg tsav tsheb me me; cov kev kho mob yog: siv cov cuab yeej los xyuas, tswj thiab kho txhua lub sijhawm thaum lub sijhawm tsim kho; siv cov hlua hlau los rub cov pawg hauv lub cev thaum tilting tshwm sim, rub thiab tsav tsheb tib lub sijhawm, thiab maj mam kho nws; tseg qhov sib txawv tsim nyog rau thawj daim ntawv tsav tsheb.
b. Torsion. Yog vim li cas rau qhov teeb meem no: lub xauv yog ib tug hinged kev twb kev txuas; txoj kev kho mob yog: xauv lub hauv ntej xauv ntawm daim ntawv pawg nrog ib daim ntawv nyob rau hauv cov kev taw qhia ntawm pawg tsav tsheb; teem lub pulley brackets nyob rau hauv qhov sib txawv ntawm ob sab ntawm cov hlau ntawv pawg kom nres qhov kev sib hloov ntawm daim ntawv pawg thaum lub dab dej; sau ob sab ntawm lub xauv buckle ntawm ob daim ntawv pawg nrog cov ntaub qhwv thiab ntoo dowels.
c. Kev sib txuas. Yog vim li cas rau qhov teeb meem: cov steel ntawv pawg yog tilted thiab khoov, uas ua rau kom cov kev tiv thaiv ntawm lub qhov; txoj kev kho mob yog: kho qhov qaij ntawm daim ntawv pawg hauv lub sijhawm; ib ntus kho cov pawg uas nyob ib sab uas tau tsav nrog lub kaum sab xis hlau vuam.
9. Kev kho cov av qhov nyob rau hauv steel ntawv pawg
Cov pob qhov uas tshuav tom qab rub tawm cov pawg yuav tsum tau rov qab ua raws sijhawm. Cov txheej txheem rov qab siv cov txheej txheem filling, thiab cov ntaub ntawv siv hauv cov txheej txheem filling yog pob zeb chips lossis nruab nrab-coarse xuab zeb.
Cov saum toj no yog cov lus piav qhia ntxaws txog kev tsim kho cov kauj ruam ntawm Larsen steel ntawv pawg. Koj tuaj yeem xa mus rau cov neeg xav tau nyob ib puag ncig koj, ua tib zoo mloog Juxiang Machinery, thiab "kawm ntxiv" txhua hnub!
