Engineering Works：Landslide Prevention Work

HOME > Engineering Works > Landslide Prevention Work

We manufacture the machinery relating to control work and and restraint work for landslide.

Landslide Prevention Works are generally classified into ① control work which purpose is to block the percolation of ground water causing the occurrence of landslide or to mitigate the landslide by dewatering from the underground, and ② restraint work which purpose is to prevent the landslide by constructing the structures to add the resistance to soil block to be slided.
Various drilling technologies such as horizontal drilling and water collecting well drilling are utilized for control works, and retaining piling, anchoring and shaft work are utilized for restraint works.

① Horizontal drilling

This is to remove ground water by drilling horizontally from ground surface to slide surface.

② Water collecting well drilling

This is to collect ground water by dewatering after drilling horizontally from collecting well with diameter of 3.5 m in case drilling length is too long.

③ Retaining piling

This is to give the resistance against slide force by installing the piles upto stable ground level deeper than slide surface.

④ Anchoring

This is to give the resistance against slide force by wire tension being connected with the fixing part of ground surface after installing the anchor upto stable ground level deeper than slide surface.

⑤ Shaft work

This is to give the resistance against slide force by installing a large diameter (3.0 - 6.5 m) reinforced concrete pile upto stable ground level deeper than slide surface.
