Bag type grouting jacking deviation rectifying construction method
The invention discloses a bag type grouting jacking deviation rectifying construction method which comprises the steps that a pile is formed below a foundation of a building, a foldable bag is arranged between the foundation and the pile, and the bag is connected through a grouting pipe; pressure grouting is conducted on the interior of the bag, pressure generated by the grout in the bag forms upward supporting force at the bottom of the foundation, and then the building is lifted; and after the building is lifted to the designed elevation, the gap between the foundation and the foundation is backfilled. According to the construction method, the pile is constructed below the foundation of the building, then the foundation is jacked in the mode of grouting the bag between the pile and the foundation, compared with a foundation grouting jacking inclination rectification method, the grouting body is separated from the foundation through the bag in the construction method, the problem that grout flows out is avoided, and therefore additional deformation of grouting is eliminated, and the construction efficiency is improved. Therefore, a pile wall does not need to be built on the outer side of the house or a bearing layer does not need to be built below the foundation, and the building safety degree and the construction efficiency in the construction process are improved.
本发明公开了一种囊式注浆顶升纠偏工法，包括：在建筑物的基础的下方形成桩，在所述基础和所述桩之间布置可折叠的囊袋，使用注浆管连接所述囊袋；向所述囊袋内进行压力注浆，所述囊袋内的浆液产生的压力在所述基础的底部形成上托力，进而对建筑物进行抬升；建筑物抬升到设计标高后，回填所述基础与地基之间的空隙。本工法采用在建筑物的基础的下方施工桩，然后通过向桩和基础之间的囊袋注浆的方式顶升基础，相比较于地基灌浆顶升纠倾法，本工法通过囊袋将注浆体与地基分隔，不会出现浆液外流的问题，从而消除注浆附加变形，因此不需要在房屋的外侧建设桩墙，或者在基础的下方建设承托层，从而提高了施工过程中的建筑安全度和施工效率。
