Title
(EN) APPARATUS FOR BI DIRECTIONAL LOAD TESTING OF DRIVEN PILES AN INJECTION PILES AND METHOD THEREOF
Abstract
(EN) An apparatus for carrying out bi directional load testing of close ended driven piles and injection piles utilizing a hydraulic jack comprising an enclosure for housing the hydraulic jack (13). The enclosure (1) includes a first hollow body (10) a second hollow body (15). The first hollow body (10) had a covered upper end (10a) and an open lower end (10b) with the upper end being capped by an attached top plate (11) having an external surface (11a) which the lower end (81b) of a first pile (81) may be axially attached to and an internal surface (lib). The open lower end (10b) has a cut out (12) originating on the edge of the open end (10b) of the first hollow body for receiving a hydraulic connection (14) for the jack (13). The second hollow body (15) is capable of housing the hydraulic jack (13) has an open upper end (15a) and a lower end (15b). The lower end (15b) is capped by an attached base plate (17) having an external surface (17a) which the upper end (82a) of a second pile (82) may be axially attached to and an internal surface (17b) for attaching the base (13a) of the hydraulic jack and an opening (16) on the capped lower end (15b) originating at a point where the edge of the lower end (15b) abuts the base plate (17) for receiving the hydraulic connection (14) for the jack. The first hollow body (10) and the second hollow body (15) are capable of axial movement relative to one another when actuated by the hydraulic jack.
