Yuav Ua Li Cas Ua Kev Ntsuas Slump

Qhov kev sim slump yog ib txoj hauv kev yooj yim tab sis tseem ceeb rau kev soj ntsuam kev ua haujlwm thiab sib xws ntawm cov pob zeb tshiab. Cov txheej txheem ncaj nraim no tsuas yog siv ob peb kauj ruam xwb, siv lub khob hliav qab, lub pas nrig steel, thiab ntsuas ntsuas.

Kauj ruam-by-Step Phau Ntawv Qhia rau Ua Qhov Kev Ntsuas Slump

1. Npaj Qhov Nto: Muab lub khob ntim rau ntawm ib lub tiaj, du, kab rov tav. Sawv ntsug ntawm lub footholds ntawm ob sab kom ntseeg tau tias lub khob hliav qab tau ruaj khov rau hauv av.
2. Sau lub khob hliav qab: Ntxiv pob zeb rau lub khob hliav qab hauv peb txheej sib npaug. Rau txhua txheej, siv cov hlau tamping pas nrig los cog cov pob zeb 25 zaug nyob rau hauv ib qho kev sib xws, kom ntseeg tau tias cov pob zeb zoo-compacted.
3. Qib saum toj kawg nkaus: Thaum lub khob ntim puv, ua tib zoo tshem tawm cov pob zeb ntau dhau los ntawm sab saum toj kom cov pob zeb ua kom zoo nrog lub khob hliav qab. Tshem tawm cov pob zeb uas nchuav ib ncig ntawm lub hauv paus ntawm lub khob hliav qab.
4. Tshem lub Cone: Maj mam thiab tsis tu ncua nqa lub khob hliav qab vertically yam tsis muaj lateral lossis twisting motion. Thaum lub khob tau muab tshem tawm, muab tso rau pem hauv ntej ntawm ib sab ntawm lub pob zeb slumped.
5. Ntsuas qhov Slump: Lub pob zeb yuav poob qis lossis qis dua. Txhawm rau ntsuas qhov slump, nteg lub steel pas nrig horizontally hla saum lub khob hliav qab, cia nws overhang lub pob zeb slumped.
6. Txiav txim siab tus nqi poob qis: Ntsuas qhov kev ncua deb ntawm lub hauv qab ntawm tus pas nrig mus rau qhov siab tshaj plaws ntawm cov pob zeb slumped, kaw qhov ntsuas mus rau qhov ze tshaj 5 hli.

Cov txiaj ntsig ntawm Slump Test

Kev ntsuam xyuas slump muab kev pom rau hauv dej-cement piv thiab tag nrho qhov zoo ntawm cov pob zeb sib xyaw. Cov txiaj ntsig feem ntau yuav poob rau hauv ib qho ntawm cov hauv qab no:

• Muaj tseeb Slump: Lub pob zeb tuav feem ntau ntawm nws lub khob hliav qab, qhia txog kev sib xyaw ua ke nrog kev ua haujlwm sib luag.
• Zero Slump: Lub pob zeb tuav nws cov duab tag nrho, qhia txog kev sib xyaw qhuav heev, uas yog tsim rau cov kev siv tshwj xeeb xws li kev tsim kho.
• Shear poob: Sab saum toj ib nrab ntawm cov pob zeb slumps mus rau ib sab, qhia tau hais tias thaum qhov sib tov muaj qee qhov kev ua haujlwm, nws yuav tsis muaj kev sib koom ua ke thiab yuav muaj dej ntau dhau. Qhov kev sib xyaw no yuav xav tau kev hloov kho thiab yuav tsum tau rov kuaj dua.
• Kaw: Lub pob zeb tawg tag thiab tsis tuav ib qho duab, qhia tias qhov sib piv ntawm cov dej-cement siab dhau lawm thiab qhov sib tov yuav tsum tau kho kom zoo.
