Tsanangudzo yeChigadzirwa

1. Tsvimbo yekuPoland rudzi rwetsvimbo yekusveta yakabatana netsvimbo yekusveta uye beam hanger. Iri pamusoro petsvimbo yekusveta, inoda kusimba zvakanyanya, saka ine dhayamita yakakura uye simbi yepamusoro kupfuura tsvimbo yekusveta, uye pamusoro payo pakanyatsotsvedzerera.

2. Basa guru:

Yakabatanidzwa nekuisa zvinhu mubhokisi rekuisa zvinhu kuti ivhare musoro wetsime uye kudzivirira mafuta, gasi, mvura kupararira.

Chinobatanidza chepakati pakati petsvimbo yekusukira nehanger yemusoro wemuse

Kuyedzwa kwedhayagiramu yekupedzisa chiratidzo.

Pedzisa mabasa akasiyana-siyana ekubvisa pombi, akadai sekurova pombi, kugadzirisa pombi.
