Chitoliro chamaluwa chachitsulo ndi njira yopangira ma tunneling ndi ntchito yomanga projekiti yothandizira otsetsereka. Amagwiritsidwa ntchito makamaka pagawo lofooka losweka, gawo lokwiriridwa mozama, gawo losakondera la khomo laphanga, gawo la mchenga, gawo la mchenga, ndi miyala panthawi yokhazikika. Chitetezo cholipiriratu kumadera monga zone zosweka.

Chitoliro chamaluwa chachitsulo ndi njira yothandiza kwambiri yomanga yothandiza popanda kukumba movutikira kwa nkhope yogwira ntchito.
