Method for correcting pile foundation offset through high-pressure grouting
The invention discloses a method for correcting pile foundation offset through high-pressure grouting. The method comprises the following steps that a stress releasing structure is arranged on the opposite side at a line offset direction and used for releasing stress and inducing displacement; and a plurality of high-pressure jet grouting piles are constructed on one side at the line deviation direction, the jet pressure of the high-pressure jet grouting piles is used for applying reverse extrusion stress to a to-be-corrected pile foundation so as to achieve the offset correction effect of thebridge pile foundation. According to the method, the extrusion force is applied to the periphery of pile foundation soil through the high-pressure grouting method to move the offset pile foundation so as to achieve the purpose of correcting the displacement of the pile foundation.
本发明公开了一种高压注浆纠正桩基偏移的方法，包括如下步骤：在位于线路偏移方向的对侧设置应力释放结构，用于释放应力和诱导位移；在位于线路偏移方向的一侧施工若干高压喷射注浆桩，利用高压喷射注浆桩的喷射压力，对待纠偏桩基施加反向挤应力，达到桥梁桩基纠偏作用。本发明通过高压注浆的方法，对桩基土周围施加挤压力，来移动偏位的桩基础，达到纠正桩基位移的目的。
