Static pressure pile pressing device

The static pressure pile pressing device comprises a counter-force frame, a counter-force cross beam and a jack, the counter-force frame comprises two parallel vertical rods, sliding grooves are formed in the inner side walls of the vertical rods in the vertical direction, the two ends of the counter-force cross beam are embedded in the sliding grooves respectively and connected to the counter-force frame in a sliding mode, and an electric hoist is arranged on the counter-force frame. A plurality of pin holes are formed in the vertical rods in the vertical direction, and clamping assemblies used for being clamped into the pin holes are arranged at the two ends of the counter-force cross beam. When the position of the counter-force beam is fixed according to the actual condition of construction, after the counter-force beam is hoisted to the designated height through the electric hoist, the clamping connection is gradually clamped into the pin hole, and the position of the counter-forcebeam is fixed.
