Foundation engineering settlement control method under unfavorable geological conditions
The invention relates to a foundation engineering settlement control method under unfavorable geological conditions, which comprises the following steps of: providing an anchor head which comprises an upper anchor plate and a lower anchor plate; the lower anchor plate is fixed to a pile body of the pile foundation, the upper anchor plate is fixed to the lower anchor plate, and the upper anchor plate is fixed to a bearing platform on the upper portion of the pile body; after the foundation is settled, a jacking device is reversely mounted at the bottom of the bearing platform; a mounting ring is detachably fixed at the position, below the lower anchor plate, of the pile body; fixing of the upper anchor plate and the lower anchor plate is removed, and the lower anchor plate and the upper anchor plate are separated through the jacking device; the pile head of the original pile body is broken and removed, and the lower anchor plate is dismantled; the lower anchor plate and the upper anchor plate are fixed again; and heightening pouring is conducted on the pile body, and the lower anchor plate is poured in the pile body. The technical problem that in the prior art, rigid connection is adopted for a settlement control structure, pile body lengthening and foundation settlement repairing are inconvenient is solved.
本发明涉及一种不良地质条件下的基础工程沉降控制方法，包括如下步骤：提供锚头，该锚头包括上锚板和下锚板；将下锚板与桩基础的桩身固定，将上锚板与下锚板进行固定，将上锚板与该桩身上部的承台固定；当基础发生沉降后，于该承台底部反向安装顶升装置；于该桩身位于该下锚板以下的位置可拆卸固定安装环；拆除该上锚板与该下锚板的固定，通过该顶升装置使该下锚板与该上锚板分离；对原该桩身的桩头进行破除，并拆除该下锚板；再次将该下锚板与该上锚板进行固定；对该桩身进行加高浇筑，将该下锚板浇筑在该桩身内。本发明发明解决了现有技术中沉降控制结构采用刚性连接不便进行桩身加长和修复基础沉降的缺点的技术问题。
