Settling and lifting method for building above existing tunnel
The invention relates to the technical field of building construction, solves the problem that a building above an existing tunnel is prone to sedimentation, and discloses a sedimentation lifting method for the building above the existing tunnel. The sedimentation lifting method comprises the following construction steps that the geological conditions of the located area, the depth and position of the tunnel and building sedimentation are surveyed; grouting is conducted outside the two sides of the tunnel to form curtain walls, grouting is conducted above the curtain walls to form a horizontal supporting platform, and the horizontal supporting platform is erected on the curtain walls on the two sides of the tunnel to form a supporting structure; grouting is conducted below a foundation slab of the building to form a shallow reinforcing layer; and grouting is conducted between the horizontal supporting platform and the shallow reinforcing layer according to the survey result, grouting is stopped after the building is lifted to the preset height, and a lifting layer is formed. The curtain wall and the horizontal supporting platform form a stool type supporting structure, the pressure of the upper structure of the tunnel is transmitted to the bottom end of the tunnel along the curtain wall, the tunnel can be protected, the stool type supporting structure can serve as a bearing layer during grouting lifting of a building, and the stability of the grouting lifting process is improved.
本申请涉及建筑施工的技术领域，修复了既有隧道上方建筑物容易发生沉降的问题，公开了一种既有隧道上方建筑物沉降抬升方法，包括以下施工步骤：勘测所处地区的地质条件、隧道的深度和位置以及建筑沉降；于隧道的两侧外注浆形成帷幕墙，帷幕墙的上方注浆形成有水平支撑平台，水平支撑平台搭设于隧道两侧的帷幕墙上形成支撑结构；于建筑物的基础底板下注浆形成浅层加固层；根据勘测结果在水平支撑平台和浅层加固层之间注浆，使建筑物抬升至预定高度后停止注浆并形成抬升层。帷幕墙和水平支撑平台形成凳子式支撑结构，将隧道上部结构的压力沿着帷幕墙传到隧道底端，既能保护隧道，又可作建筑物注浆抬升时的持力层，提高注浆抬升过程的稳定性。
