- Piping yeeb nkab nkag
1) Ua ntej kev tsim kho, cov qauv pawg yuav tsum tau tswj raws li tus qauv tsim qauv, thiab cov qauv pawg yuav tsum tau tshuaj xyuas ib qho los ntawm ib qho raws li qhov axis, thiab cov ntaub ntawv ntsuas yuav tsum tau ua. Piling kev tsim kho tsuas yog ua tau tom qab kev tshuaj xyuas yog lawm. Tom qab pawg tsav tsheb kauv yeeb nkab pawg thauj mus rau qhov chaw, ib qho taw tes ntawm lashing yog siv rau hoisting. Thaum cov pawg tau nqa mus rau qhov chaw pawg, cov pawg tau muab tso rau. Cov pawg tsav tsheb kauv cov yeeb nkab pawg yog ua raws li cov pawg ua haujlwm tso tawm ua ntej kom ntseeg tau qhov tseeb verticality thaum nkag mus. Ua ntej piling, ib lub hau tshwj xeeb yuav tsum tau muab tso rau ntawm lub taub hau ntawm pawg, thiab ib qho nyuaj ntoo shock-absorbing ncoo yuav tsum tau muab tso rau ntawm pawg cap. Thaum pawg tsav tsheb kauv yeeb nkab pawg yog nqa mus rau pawg pawg rau kev ntxig, vim tag nrho qhov hnyav ntawm lub cev ntawm pawg thiab pawg hau thiab pawg rauj thaum muab tso rau saum pawg, nws yuav nws tus kheej-sab thiab nkag mus rau hauv. cov av hauv qhov ntau. Nws yuav hammered tom qab nws tog mus rau theem ruaj khov;
2) Thaum pib pawg tsav tsheb, pawg tsav tsheb yuav tsav kom qhuav vim muaj qhov nkag mus ntau heev. Thaum pib qhov kev ua haujlwm rauj, kev sim tsav tsheb yuav tsum tau ua kom maj mam thiab sib cuam tshuam kom txog thaum cov pawg nkag mus rau qhov tob hauv av. Nruam rauj tsis pub. Thaum lub sij hawm piling txheej txheem, qhov verticality ntawm pawg tsav tsheb qhia pas nrig thiab pawg yuav tsum tau kho txhua lub sij hawm, thiab pawg rauj, pawg cap thiab pawg yuav tsum tau khaws cia rau tib lub axis longitudinal;
3) After driving the spiral pipe pile for 1 to 2 meters, the verticality should be recalibrated. When the pile is driven to a certain depth and the pile driving quality is good after review, the hammering should be continued until the hammering is stopped at 60cm to 80cm above the water surface. Connect the piles and repeat the above steps until the design elevation is reached. If the pile position is found to be tilted during the construction process (>1/100L L-steel pawg ntev), cov yeeb nkab steel pawg yuav tsum tau kho lossis rub tawm hauv lub sijhawm thiab rov tsim kho;
4) Qhov faus qhov tob ntawm pawg tsav tsheb kauv yeeb nkab pawg: 10m thoob plaws hauv lub txaj dej, thiab tus nqi dab dej hauv tus naj npawb ntawm kev tawm tsam ib feeb yuav tsum tsis pub tshaj 5 hli.
- Txuas pawg
Pile lub cev kev sib txuas ntawm pawg tsav tsheb kauv yeeb nkab pawg adopts pob tw vuam rau saum thiab hauv qab ntawm pawg pawg. Ua ntej vuam, qhov deformed thiab puas ntawm cov yeeb nkab hauv qab yuav tsum tau kho. Cov xeb, dej los yog roj sludge thiab xuab zeb ntawm qhov kawg ntawm cov yeeb nkab sab saud yuav tsum tau muab tshem tawm. Lub vuam sib txuas yuav tsum tau polished kom qhov sib txawv ntawm cov pawg sab sauv thiab sab qis yog 2 mus rau 4 hli. Nyob rau tib lub sijhawm, ntau txheej vuam yog siv los vuam. Tom qab ua tiav txhua txheej ntawm welds, tshem tawm cov vuam slag nyob rau hauv lub sij hawm thiab ua ib qho kev soj ntsuam pom. Txhua txheej ntawm welds yuav tsum tau staggered, thiab welding blocks yuav tsum tau ntxiv nyob ib ncig ntawm cov pawg kom ntxiv dag zog rau kev sib txuas ntawm pawg sab sauv thiab qis. Tom qab vuam tiav lawm, nws yuav tsum tau txias rau ntau tshaj 5 feeb ua ntej hammering thiab piling.
- Welded pawg npog
Tom qab kev tsim kho ntawm cov kav yeeb nkab ua tiav, cov xuab zeb yog manually nchuav rau hauv pawg mus rau sab saum toj ntawm pawg, pawg npog yog welded rau sab saum toj ntawm cov yeeb nkab steel, thiab 8 mus rau 12 20mm anchoring steel. bars yog welded rau sab nrauv phab ntsa.
