Kupera pansi ndi njira yomwe imagwiritsidwa ntchito pokonzekera, kusanja, ndi kusalala kwa konkire.Zimaphatikizapo kugwiritsa ntchito makina apadera okhala ndi ma disc kapena mapepala opera a diamondi kuti akupera pamwamba pa konkire, kuchotsa zolakwika, zokutira, ndi zowonongeka.Kupera pansi kumachitika kawirikawiri musanagwiritse ntchito zokutira, zokutira, kapena kupukuta konkriti kuti zitheke bwino komanso zomaliza.
Kupera konkriti kumapanga tinthu tating'ono ting'onoting'ono tafumbi tomwe timatha kuyenda ndi mpweya ndikufalikira kudera lonse la ntchito.Fumbi limeneli lili ndi zinthu zovulaza, monga silika, zomwe zingayambitse mavuto aakulu a kupuma ngati munthu atazikoka kwa nthawi yaitali.Vacuum ya fumbi idapangidwa kuti igwire ndi kukhala ndi fumbi, kukonza mpweya wabwino komanso kuteteza thanzi la ogwira ntchito ndi aliyense wapafupi.Kukoka fumbi la konkire kumatha kuyambitsa zovuta zanthawi yayitali komanso zazitali, monga kupuma movutikira, kutsokomola, komanso matenda am'mapapo monga silicosis.
A chotsitsa fumbi la konkriti, wotchedwanso fumbi vacuum kapena fumbi wotolera, n'kofunika kwambiri mnzako wa pansi chopukusira.Pogwiritsa ntchito avacuum fumbi, mumachepetsa kuwonetseredwa kwa ogwira ntchito ku tizigawo towopsa izi, kupanga malo otetezeka kwa aliyense wogwira nawo ntchito.Kugwiritsira ntchito vacuum system kumachepetsa kufalikira kwa fumbi, kusunga malo ogwirira ntchito ndi kuyeretsa mosavuta ntchitoyo ikamalizidwa.
Ngati kupera kwa konkire kukuchitika m'malo ogulitsa kapena okhalamo, kugwiritsa ntchito chopukutira fumbi kungapangitse kukhutira kwamakasitomala.Makasitomala adzayamikira malo oyeretsera komanso otetezeka pantchitoyo komanso ikatha.
Kumbukirani kuti mukamagwiritsa ntchito chopukusira konkriti ndikonkire vacuum zotsukirandikofunikira kuvala zida zoyenera zodzitetezera (PPE), kuphatikiza chigoba chafumbi kapena chopumira, magalasi oteteza makutu, ndi zida zina zilizonse zofunika kuti mukhale ndi chitetezo chokwanira panthawi yopera konkire.
