Device and method for detecting vertical bearing capacity of root pile of power transmission tower

The invention discloses a device and method for detecting the vertical bearing capacity of a root pile of a power transmission tower. The method comprises the following steps: S1, mounting a temporary bracket and a loading beam; s2, mounting a conversion plate on the counter-force pile, and connecting the conversion plate to a loading beam through a connecting rod; s3, mounting a loading barrel, a jack, a displacement meter and the like on the top of the detection pile; and S4, after pre-pressing, vertical compression bearing capacity detection is carried out. The uplift bearing capacity detection method comprises the following steps: S1, mounting a counter-force pier and a loading beam; s2, sequentially installing a steel base plate, a jack and a steel base plate above a loading beam at the top of the detection pile; s3, mounting a conversion plate at the top of the detection pile, and fixing the conversion plate on the jack through a connecting rod; and S4, vertical uplift bearing capacity detection is carr
