Pile foundation reinforcing method
The invention relates to a pile foundation reinforcing method. The method comprises the following steps that S1, a foundation pit is excavated, the foundation pit is formed through excavation, the bottom of the foundation pit is lower than the lower surface of a pile bearing platform, and a construction space is formed between the bottom of the foundation pit and the lower surface of the pile bearing platform; S2, structure construction is reinforced: S2-1, pile construction is reinforced: constructing at the bottom of the foundation pit and on one side of the vertical projection of the pile cap at the bottom of the foundation pit to form a reinforcing pile; and S2-2, reinforcing plate construction is conducted, specifically, a reinforcing plate is formed on the lower surface of the pile cap through construction, and the reinforcing plate is fixedly connected with the reinforcing pile. S3, the foundation pit is backfilled: S3-1, filling a first filler layer, and filling a first filler between the lower surface of the reinforcing plate and the pit bottom of the foundation pit to form the first filler layer. and S3-2, second filler layer filling is conducted, specifically, the side wall of the first filler layer is filled with the second filler layer, the second filler layer is vibrated and compacted from the upper surface of the second filler layer, and the upper surface of the second filler layer is higher than the lower surface of the reinforcing plate. The method has the effect of reducing damage to the pile cap during pile foundation reinforcement.
本申请涉及一种桩基加固方法，其包括如下步骤，S1，基坑开挖，开挖形成基坑，基坑坑底低于桩承台下表面，基坑的坑底与桩承台下表面之间形成施工空间。S2、加固结构施工，S2‑1，加固桩施工，在基坑坑底且位于桩承台在基坑坑底的竖向投影一侧施工形成加固桩。S2‑2，加固板施工，在桩承台的下表面施工形成加固板，加固板与加固桩固定连接。S3、基坑回填，S3‑1，第一填料层填充，在加固板下表面与基坑的坑底之间填充第一填充料形成第一填料层。S3‑2，第二填料层填充，在第一填料层的侧壁填充形成第二填料层，自第二填料层的上表面振密第二填料层，第二填料层的上表面高于加固板的下表面。本申请具有减少桩基加固时对桩承台的损伤的效果。
