Dongosolo la Mabokosi a M'ngalande (lomwe limatchedwanso kuti zishango za m'ngalande, mapepala a m'ngalande, dongosolo loteteza), ndi njira yotetezera yomwe imagwiritsidwa ntchito kwambiri pakufukula ngalande ndi kuyika mapaipi ndi zina zotero. Chifukwa cha kulimba kwake komanso kusavuta kugwiritsa ntchito, dongosolo la mabokosi a m'ngalande lopangidwa ndi chitsulo lapeza msika wake padziko lonse lapansi.
Lianggong, monga m'modzi mwa opanga ma formwork ndi ma scaffolding otsogola ku China, ndiye fakitale yokhayo yomwe imatha kupanga makina a trench boxes. Makina a trench boxes ali ndi zabwino zambiri, chimodzi mwa izo ndichakuti amatha kukhala opendekera chifukwa cha bowa lomwe lili mu spindle lomwe limapindulitsa kwambiri wopanga. Kupatula apo, Lianggong imapereka makina osavuta kugwiritsa ntchito a trench lining omwe amawongolera kwambiri magwiridwe antchito. Kuphatikiza apo, miyeso ya makina athu a trench boxes imatha kusinthidwa malinga ndi zosowa za makasitomala monga m'lifupi, kutalika ndi kuzama kwakukulu kwa ngalande. Kuphatikiza apo, mainjiniya athu apereka malingaliro awo ataganizira zonse kuti apereke chisankho chabwino kwa makasitomala athu.
Mu nkhani ya lero, tiwona bwino zinthu zathu zogulitsidwa kwambiri -- Trench Boxes system, kuphatikizapo mawonekedwe ake, zigawo zake, zowonjezera zake ndi zina zotero.

Ndizo zonse zomwe zili mu dongosolo la ma trench box amakono. Lianggong akulandira bwino abwenzi ochokera padziko lonse lapansi kuti abwere kudzaona fakitale yathu ndipo akukhulupirira kuti makasitomala ndi omwe akutsogolera. Tikuyembekezera kuchita bizinesi ndi makasitomala athu potsatira mfundo yoti tonse tipindule. Kuti mudziwe zambiri, musazengereze kulankhulana nafe.
