Ancient tower inclination rectification method for manually regulating and controlling foundation settlement
The invention provides an ancient tower inclination rectification method for manually regulating and controlling foundation settlement, which comprises the following steps of: constructing a first diaphragm wall and a second diaphragm wall in the direction opposite to the inclination direction of a tower body, excavating earthwork between the first diaphragm wall and the second diaphragm wall to form a working space, installing a plurality of length-adjustable inner supports in the working space, the lengths of the inner supports are adjusted from bottom to top to shorten the inner supports, and the inner supports from bottom to top become shorter and shorter; therefore, the tower body is driven to tilt back in the direction opposite to the inclination direction of the tower body. And after the inner support is adjusted for one round from bottom to top in the first round and the tower body stops tilting back, the adjustment of the inner support in the next round is repeated according to the tilting-back effect of the tower body until the tower body is aligned. In the rectifying process of the tower body, the bearing soil layer at the bottom of the tower footing is not excessively disturbed, and the rectifying purpose is achieved by means of the change of peripheral stress under the condition that the bearing capacity of the original tower footing is not changed in the rectifying process of the tower body.
本发明提供一种人工调控地基沉降古塔纠倾方法，包括以下步骤：在塔体倾斜相反方向，施工第一地连墙和第二地连墙，开挖第一地连墙和第二地连墙之间的土方形成工作空间，在工作空间内安装若干道长度可调的内支撑，从下到上调节各个内支撑长度使其缩短，自下而上的内支撑越来越短；从而带动塔体向自身的倾斜的相反方向回倾；第一轮从下到上对内支撑调节完成一轮，塔体停止回倾后，根据塔体的回倾效果重复下一轮对内支撑的调节直到塔体回正。本发明在塔体纠偏过程中，不过度扰动塔基底部承载土层，确保塔体在纠偏过程中原塔基承载力不变的情况下依靠外围应力变化达到纠偏目的。
