Chiyambi chatsatanetsatane chazabwino za pansi pa chidebe!

Zinthu zapansi chidebendi tropical hardwood.Chifukwa cha maonekedwe ake apamwamba ndi mtundu wokopa maso, ili ndi zowonongeka zochepa komanso zowundana.Kwa zaka zambiri, wakhala wotchuka wa zipangizo pansi chidebe.Pansi pa chidebe nthawi zambiri amagwiritsa ntchito nkhuni zolimba za kumalo otenthazi ngati zida zopangira.Choncho, amakondedwa ndi eni ake ambiri a bokosi.Nthawi zambiri masambawa amakhala ochokera ku Southeast Asia, chifukwa chiyani?Makamaka chifukwa mtundu wamtunduwu uli ndi zolakwika zochepa monga mafundo, mfundo zakufa, nyongolotsi, zowola ndi ming'alu.Zokolola zakuthupi ndizokwera kwambiri, ndipo zimakhala ndi makina abwino.
Pansi pa chidebe chili ndi zabwino zapadera ngati chidebe pansi.Pali mitundu yambiri yamatabwa, ndipo chuma chingapezeke kwanuko m'malo osiyanasiyana, ndipo n'zosavuta kupanga unyolo wa mafakitale.Pansi pansi pa chidebe cha nsungwi, mwayi uwu wa matabwa a chidebe ndi wowonekera kwambiri.Malo okhawo okhala ndi nkhalango ndi omwe amatha kukonza matabwa a matabwa pamalowo.Kuyambira panjira yoyamba yopangira zida zopangira pansi, kuwongolera mwamphamvu kumatsimikizira kuti makasitomala atha kuzigwiritsa ntchito ndi mtendere wamumtima.
Kuchokera pamalingaliro amtundu wonse wa chidebe chowuma chonyamula katundu (chotengera).Choyimira chachikulu chimapangidwa ndi zitsulo, kuphatikizapo zitsulo zazitsulo monga zinthu zazikulu kumbali zisanu, ndipo pansi pake amapangidwa ndi matabwa otalika komanso opingasa ogwirizana ndi matabwa.Kuphatikizika kwathunthu kwa kuuma ndi kusinthasintha kumapewa zovuta zazitsulo zonse.
Kuchokera kuzinthu zakuthupi za nkhuni zokha.Modulus ya elasticity ya matabwa pansi ndi yamphamvu kuposa yachitsulo.Zinthu zolemetsa zikadutsa pansi pa matabwa a chidebecho, mbale yapansi ya chidebecho imatha kubwezeretsanso kusungunuka kwake koyambirira mu nthawi yochepa, kuisunga mopanda phokoso, ndipo sipanga nthaka yonyowa.
