Deviation rectifying and reinforcing method suitable for draught fan foundation on super-thick layer backfill soil
The invention discloses a deviation rectifying and reinforcing method suitable for a fan foundation on super-thick backfill soil, which is characterized in that a sand cushion layer is arranged between the foundation and the bottom surface of a foundation cushion layer, sand is sand with good grading, and the sand cushion layer is wrapped and sealed by a geomembrane with stable performance; geomembrane pipes are arranged on the periphery of the edge of a sand cushion layer at equal intervals to serve as water flushing and sand suction channels, in order to control the sand suction amount of each geomembrane channel at different depths, grid division is conducted from the edge of the foundation in the sand suction direction, and the sand suction volume amounts of different grids are calculated by adjusting different gradients of the foundation; meanwhile, water flushing and sand suction are conducted on the sand cushion layer through water flushing and sand suction equipment, finally, sand body resonance is caused in the sand cushion layer through a high-frequency vibrator, stable development of sand body sedimentation is accelerated, foundation inclination can be uniform, meanwhile, multiple monitoring methods are adopted, and the precision and accuracy of foundation sedimentation data are improved.
本发明公开了一种适用于超厚层回填土上风机基础纠偏加固方法，通过在地基与基础垫层底面之间设置一层砂垫层，砂料为级配良好砂，砂垫层用性能稳定的土工膜进行包裹密封，在砂垫层边缘周圈等间距布置土工膜管作为冲水吸砂通道，为控制每个土工膜通道不同深度处的吸砂量，采取在吸砂方向上从基础边缘处开始进行网格划分，根据调节基础不同倾斜度计算不同网格处吸砂的体积量，同时利用冲水吸砂设备对砂垫层进行冲水吸砂，最后利用高频振捣器在砂垫层中引起砂体共振，加速砂体沉降稳定发展，使得基础倾斜能够均匀，同时采用多种监测方法，提高基础沉降数据的精度和准确性。
