Txhua tus neeg ua haujlwm no yuav tsum ua raws li cov qauv kev nyab xeeb tshwj xeeb uas tau teev tseg hauv OSHA Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv Txoj Cai rau Kev Tsim Kho, Subpart P, hu ua "Excavations." Lub thawv trench thiab lwm yam kev ntsuas kev nyab xeeb kuj tseem yuav tsum tau muaj nyob rau hauv qhov ntxig lossis qhov chaw txais tos ntawm trenchless kev tsim kho.

Cov thawv trench feem ntau yog tsim los ntawm qhov chaw siv excavator lossis lwm yam khoom siv hnyav. Ua ntej, ib daim ntawv steel yog muab tso rau hauv av. Spreaders (feem ntau yog plaub) txuas rau ntawm daim ntawv. Nrog rau plaub qhov kev nthuav dav txuas vertically, lwm nplooj ntawv txuas nrog rau saum. Ces tus qauv yog tig upright. Tam sim no rigging yog txuas mus rau lub thawv thiab nws yog lifted thiab muab tso rau hauv lub trench. Ib tus neeg ua haujlwm yuav siv txoj hlua khi los txhim kho lub thawv trench rau lub qhov.

Qhov laj thawj tseem ceeb rau lub thawv trench yog kev nyab xeeb ntawm cov neeg ua haujlwm thaum lawv nyob hauv lub trench. Trench shoring yog ib lo lus hais txog cov txheej txheem ntawm kev khi cov phab ntsa ntawm tag nrho cov trench kom tiv thaiv kev tawg. Cov tuam txhab ua haujlwm no yog lub luag haujlwm rau kev nyab xeeb ntawm cov neeg ua haujlwm thiab yuav tsum lav rau txhua qhov kev tsis saib xyuas tsis zoo.
