Embodiment Construction
[0032] The idea of correcting the deviation of the present invention: according to the settlement and inclination of the building, a jack cap (as a loading platform) is added to the pile with a large settlement, and the building is used as a reaction point, and the load is gradually loaded by the jack, relying on the self-weight of the building. Pile, so that the pile end is relocated to the bearing layer (that is, re-reaching the stable soil layer) to meet the later use of bearing capacity, while the jack cap is used as a counter force point to lift the building that has subsided due to collapsing and achieve the purpose of correcting the deviation. Because the self-weight of the building is used to press the pile, the present invention can not only strictly control the settlement difference of the original pile, but also ensure the subsequent bearing capacity of the original pile, and the force of each structure is reasonable during the deviation correction and reinforcement...
