Nchifukwa chiyani mukufunikira chotsukira fumbi pogaya pansi pa konkriti?

Kupera pansi ndi njira yomwe imagwiritsidwa ntchito pokonzekera, kulinganiza, komanso kusalala pamwamba pa konkire. Kumaphatikizapo kugwiritsa ntchito makina apadera okhala ndi ma disc kapena ma pad opera opangidwa ndi diamondi kuti apere pamwamba pa konkire, kuchotsa zolakwika, zokutira, ndi zodetsa. Kupera pansi kumachitika nthawi zambiri musanagwiritse ntchito zokutira, zokutira pamwamba, kapena kupukuta pamwamba pa konkire kuti zikhale zosalala komanso zofanana.

Kupera konkriti kumapanga fumbi lochepa kwambiri lomwe limatha kuuluka ndi kufalikira pamalo onse ogwirira ntchito. Fumbi ili lili ndi zinthu zovulaza, monga silica, zomwe zingayambitse mavuto aakulu opumira ngati litapumidwa kwa nthawi yayitali. Chotsukira fumbi chimapangidwa kuti chigwire ndikusunga fumbi, kukonza mpweya wabwino ndikuteteza thanzi la ogwira ntchito ndi aliyense amene ali pafupi. Kupuma fumbi la konkriti kungayambitse mavuto azaumoyo nthawi yomweyo komanso kwanthawi yayitali, monga kukwiya kwa kupuma, chifuwa, komanso matenda osatha a m'mapapo monga silicosis.

A chotsukira fumbi la konkire, yomwe imadziwikanso kuti chotsukira fumbi kapena chosonkhanitsira fumbi, ndi bwenzi lofunika kwambiri la chopukusira pansi. Chopukusira pansi ndi chotulutsira fumbi la konkire ndi zida ziwiri zofunika zomwe zimagwiritsidwa ntchito pamodzi popukusira konkire. Pogwiritsa ntchitofumbi losalowa, mumachepetsa kufalikira kwa ogwira ntchito ku tinthu toopsa timeneti, zomwe zimapangitsa kuti malo otetezeka kwa aliyense amene akugwira ntchitoyo akhale otetezeka. Popanda fumbi losambitsa fumbi, fumbi la konkire limatha kukhazikika pamalo oyandikana, zida, ndi nyumba, zomwe zimapangitsa malo ogwirira ntchito kukhala osokonezeka komanso ovuta. Kugwiritsa ntchito makina osambitsira fumbi kumachepetsa kufalikira kwa fumbi, kusunga malo ogwirira ntchito oyera komanso kuyeretsa mosavuta ntchito ikatha.

Ngati ntchito yopera simenti ikuchitika m'malo amalonda kapena m'nyumba, kugwiritsa ntchito chotsukira fumbi kungathandize makasitomala kukhutira. Makasitomala adzasangalala ndi malo ogwirira ntchito aukhondo komanso otetezeka panthawi ya ntchito komanso pambuyo pake.

Kumbukirani kuti mukamagwiritsa ntchito chopukusira konkire ndichotsukira vacuum cha konkritiNdikofunikira kuvala zida zoyenera zodzitetezera (PPE), kuphatikizapo chigoba cha fumbi kapena chopumira, magalasi oteteza, zoteteza kumva, ndi zida zina zilizonse zofunika kuti zitsimikizire kuti ndi zotetezeka kwambiri panthawi yopera konkire.
