Introduction of Construction Methods
(large drilling construction)
Applicable for drilling works even at an underpass, indoors and in narrow spaces.
This is a drilling method by using large type drilling machine to circulate slurry by using forward circulation method.
Inject excavation slurry by using a side-pump, then discharge the excavated musk out of a hole by the fluid moving method.
Cast-in-place concrete pile, H steel pile, steel pipe piles can be casted.
|Application||Cast-in-place pile||Preboring work for ready-made pile|
|Preventive pile||Foundation work at low attitude head pile|
|Soldier pile for retaining wall||Foundation work at narrow spaces or the like|
|Steel pipe pile||Iron tower foundation and so on|
