Minakvapak filtering construction is a filtering construction, which enables obtaining of maximal well capacity without endangering optimal function, stability and durability of the well. Technical problem has been solved by means of making an internal construction composed of a main column (1) with drilled openings (2), welded bars (3), a coupling (4), which is welded onto the end of the main column (1), as well as spirally wound wire (5), a wrapped inox sieve (6), which is fixed by means of spirally wound wire (7), and an external construction composed of rings (8) and (9), on which are welded bars (10), around which is wound wire (11), enclosed with an inox sieve (12), which is attached by means of spirally wound wire (13), wherein is welded a clamp (14) in aim to improve lateral pressure resistance. Formation of a chamber for pouring particulate material and completion of final filtering construction is done by welding of a ring (15) on the upper side and a ring (16) on the lower side and pouring particulate material through openings (17). |
