Taw qhia rau cov txheej txheem kev tsim kho ntawm cov yeeb nkab steel

Lub hom phiaj ntawm kev tsim cov yeeb nkab steel yog hloov cov khoom thauj ntawm lub tsev sab saud mus rau hauv cov av sib sib zog nqus nrog lub peev xwm muaj zog dua los yog ua kom cov av tsis muaj zog los txhim kho cov kabmob muaj peev xwm thiab compactness ntawm lub hauv paus av. Yog li ntawd, kev tsim cov yeeb nkab pawg yuav tsum tau ua kom ntseeg tau. zoo, txwv tsis pub lub tsev yuav tsis ruaj khov. Cov kauj ruam ntawm kev tsim cov yeeb nkab yog:

1. Kev soj ntsuam thiab teeb tsa: Tus kws tshaj lij kev tshawb fawb tau teeb tsa cov pawg raws li daim ntawv qhia pawg tsim qauv thiab kos cov ntsiab lus ntawm pawg nrog cov ntoo lossis ntoo tshauv dawb.

2. Tus neeg tsav tsheb pawg nyob rau hauv qhov chaw: Cov neeg tsav tsheb pawg nyob rau hauv qhov chaw, ua kom lub tog raj kheej txoj hauj lwm, thiab nqa tawm kev tsim kho vertically thiab stably kom ntseeg tau tias nws tsis qaij lossis txav mus los thaum tsim kho. Tus neeg tsav tsheb pawg tau muab tso rau ntawm txoj hauj lwm pawg, nqa cov yeeb nkab pawg rau hauv pawg tsav tsheb, tom qab ntawd muab cov pawg kawg ntawm qhov chaw ntawm pawg, tsa lub mast, thiab kho cov theem thiab pawg hauv nruab nrab.

3. Welding pile tip : Siv cov lus qhia uas siv los ua piv txwv. Tus ntoo khaub lig-pile taub hau yog muab tso rau ntawm qhov chaw pawg tom qab kuaj xyuas, thiab hauv qab kawg phaj ntawm seem yeeb nkab pawg yog welded rau nws qhov chaw. Lub vuam yog ua tiav siv CO2 shielded vuam. Tom qab welding, cov lus qhia pawg yog pleev xim rau anti-corrosion asphalt.

4. Verticality detection: Kho qhov ntev ntawm cov roj ntsaws pas nrig ntawm pawg tsav tsheb ceg lub tog raj kheej kom ntseeg tau tias pawg tsav tsheb platform yog theem. Tom qab pawg yog 500 hli rau hauv av, teeb tsa ob lub theodolite hauv kev sib koom ua ke los ntsuas qhov ntsug ntawm pawg. Qhov yuam kev yuav tsum tsis pub ntau tshaj 0.5%.

5. Pile pressing: Cov pawg tuaj yeem nias tau tsuas yog thaum lub pob zeb ua kom muaj zog ntawm pawg mus txog 100% ntawm lub zog tsim, thiab pawg tseem nyob ntsug yam tsis muaj qhov txawv txav raws li kev txheeb xyuas ntawm ob lub theodolite. Thaum lub sij hawm nias, yog tias muaj cov kab nrib pleb loj, qaij, lossis tam sim ntawd deflection ntawm pawg lub cev, pawg tuaj yeem nias. Kev tsim kho yuav tsum raug tso tseg yog tias muaj qhov tshwm sim xws li kev txav mus los thiab kev hloov pauv loj hauv kev nkag mus, thiab kev tsim kho yuav tsum rov pib dua tom qab tuav lawv. Thaum nias lub pob, xyuam xim rau qhov ceev ntawm pawg. Thaum cov pawg nkag mus rau hauv cov xuab zeb txheej, qhov ceev yuav tsum tau ceev kom tsim nyog los xyuas kom meej tias cov pawg lus muaj peev xwm nkag mus. Thaum cov kabmob txheej mus txog lossis cov roj siab dheev nce, cov pawg yuav tsum maj mam txo qhov nrawm kom tiv thaiv pawg tawg.

6. Pile kev twb kev txuas: Feem ntau, qhov ntev ntawm ib leeg-section yeeb nkab pawg tsis tshaj 15m. Yog tias qhov tsim pawg ntev ntev dua li qhov ntev ntawm ib pawg pawg, yuav tsum muaj kev sib txuas ntawm pawg. Feem ntau, cov txheej txheem vuam hluav taws xob yog siv los txuas cov pawg sib txuas. Thaum vuam, ob tug neeg yuav tsum tau welding symmetrically tib lub sijhawm. , cov welds yuav tsum tsis tu ncua thiab tag nrho, thiab yuav tsum tsis muaj kev tsim kho. Tom qab kev sib txuas ntawm pawg ua tiav, nws yuav tsum tau kuaj xyuas thiab lees txais ua ntej kev tsim kho ntawm pawg tuaj yeem txuas ntxiv mus.

7. Pile feeding: Thaum cov pawg raug nias rau 500mm los ntawm qhov chaw sau, siv cov khoom noj khoom noj los nias lub pawg kom nce siab, thiab ua kom lub siab zoo li qub. Ua ntej pub rau pawg, qhov tob ntawm pawg pub mis yuav tsum tau xam raws li cov qauv tsim, thiab pawg pub qhov tob yuav tsum raug xam raws li cov qauv tsim. Kos lub cuab yeej. Thaum cov pawg xa mus txog li 1m ntawm qhov siab tsim, tus neeg soj ntsuam qhia cov neeg tsav tsheb pawg kom txo cov pawg tsav tsheb ceev thiab taug qab thiab saib xyuas cov khoom xa tuaj. Thaum cov khoom xa tuaj mus txog qhov tsim qhov siab, lub teeb liab raug xa mus kom tsis txhob xa cov pawg.

8. Cov pawg kawg: Kev tswj ob npaug ntawm cov nqi siab thiab qhov ntev ntawm pawg yuav tsum tau ua thaum lub sij hawm tsim kho engineering piles. Thaum nkag mus rau hauv cov kabmob txheej, pawg ntev tswj yog txoj hauv kev tseem ceeb, thiab kev tswj tus nqi siab yog qhov ntxiv. Yog tias muaj qhov txawv txav, chav tsim tsim yuav tsum tau ceeb toom rau kev tuav.
