Bi-directional Single-acting hydraulic cylinder Pile Load Test

摘要

The present invention is installed to the outside by a spring, and then the internal termination bidirectional single-acting yuapjaek pile load test to restore a derived stroke cylinder there is provided a bi-directional pile load test apparatus using a spring to restore a single type yuapjaek to remove the space generated in the cylinder. ; to achieve the above object Spring restore a single type bi-directional pile load test device and a lower plate-shaped member having a predetermined thickness and diameter using yuapjaek for; And the lower plate and the lower member being located to the lower plate-like member; The award, which is located between the return spring and the lower plate member and a single type yuapjaek; The peg being fixed to a predetermined position in a state of being spaced from said lower plate-like member, the lower displacement measuring rod; And yuapjaek displacement gauge, which is installed fixed to the side of the spring to restore a single type yuapjaek; And a hydraulic pump 370 for supplying the hydraulic pressure to the spring restoring a single type yuapjaek; And a hydraulic hose for supplying hydraulic pressure generated from the hydraulic pump; Characterized by consisting of a load and pressure regulator.
