Preferably, the hardened system of above-described generation power foundation of wind power cyclic group plinth, the described anchoring of lower anchor pole in sole plate is divided into upper and lower two parts: bottom is anchoring section, is injected with epoxy resin between anchor pole and concrete; Top is free segment, and overcoat has PVC sleeve pipe, is cast-in-place high-strength mortar cushion block between described switching beam and sole plate.
Compared to the prior art the utility model has following beneficial effect:
1. the hardened system of generation power foundation of wind power cyclic group plinth that provides of the utility model, reasonable in design, firm stable, easy to implement, effectively can solve discharge ring basis fatigue failure.
2. the hardened system of generation power foundation of wind power cyclic group plinth that provides of the utility model, except the crack in discharge ring base concrete is processed, also precompression is applied to the position of discharge ring periphery fatiguability cracking, reduce the tensile stress that these positions produce under blower fan Fatigue Load, make it to ftracture again.In addition, prestressing force makes the multidirectional pressurized of concrete, and intensity improves.
3. the utility model prestressing force is pressed on the realization of concrete stub upper surface with the combination steel framed concrete beam of regular hexagon plane distribution; Steel framed concrete beam can also increase discharge ring buried depth, produces lateral pressure, and the anchored force making to act on flange at the bottom of discharge ring reduces.
4. the utility model girder steel end prestressed anchor composite member anchors into sole plate; Connect switching beam between the upper anchor pole of prestressed anchor composite member and lower anchor pole, make anchor pole and lower anchor pole have dual prestressing force effect, reduce the Fatigue Stress Amplitude of anchor pole tension further, make the anchorage effect of anchor pole more stable.
