Reinforcing method for secondary pressure grouting root pile

The invention relates to the technical field of pile foundation reinforcement, in particular to a reinforcing method for a secondary pressure grouting root pile. The reinforcing method can rapidly, timely and efficiently reinforce a building which is just in a high settlement rate, so that the disturbance range of foundation soil is small, the additional settlement amount of construction is small, the construction cost is low, the construction period is short, the effect is fast, safety and reliability are achieved, and the reinforcing effect is remarkable. 本发明涉及桩基加固技术领域，尤其涉及一种二次压力灌浆树根桩的加固方法。本发明公开了一种二次压力灌浆树根桩的的加固方法，该加固方法能快速及时高效的加固正处于沉降速率较快的建筑物，对地基土的扰动范围较小，施工的附加沉降量也较小，施工成本低，工期短，见效快，安全可靠，加固效果显著。
