Abstract

Przedmiotem zgłoszenia jest mikropal śrubowy helikalny z otworami. Mikropal śrubowy do wzmacniania fundamentów z własnością wtłaczania kompozycji iniekcyjnych o budowie profilu ukształtowanym z dziewięciu skręconych pod kątem skrzydełek tworzących helisę, charakteryzujący się: Sekcją bazową (1) o kształcie helisy, którą można łączyć z kolejnymi sekcjami do żądanej głębokości; Wewnętrznym kanałem przelotowym (2) biegnącym przez całą długość mikropala, umożliwiającym kontrolowane wtłaczanie suspensji cementowych w grunt; Otworami bocznymi (3) umieszczonymi po obu stronach mikropala, łączącymi się z kanałem przelotowym (2) i umożliwiającymi dodatkową ścieżkę wtłaczania materiałów wzmacniających; Mechanizmem gwintowania (4) na końcach kanału przelotowego (2), pozwalającym na przedłużanie długości mikropala i dostosowanie do różnych głębokości fundamentów; Końcówką (5), ułatwiającą wkręcanie mikropala w grunt; Ostrym grotem (6) zapobiegającym zapchaniu się kanału przelotowego (2) podczas wbijania.The subject of the application is a helical screw micropile with holes. A screw micropile for reinforcing foundations with the property of injecting injection compositions with a profile structure shaped from nine angled wings forming a helix, characterized by: A base section (1) in the shape of a helix, which can be connected to subsequent sections to a desired depth; An internal passage channel (2) running along the entire length of the micropile, enabling controlled injection of cement suspensions into the ground; Side holes (3) located on both sides of the micropile, connecting with the passage channel (2) and enabling an additional path for injecting reinforcing materials; A threading mechanism (4) at the ends of the passage channel (2), enabling extension of the length of the micropile and adjustment to different foundation depths; A tip (5) facilitating screwing the micropile into the ground; A sharp tip (6) prevents clogging of the passage channel (2) during driving in.
