Flexible variable-rigidity circulating water pipe foundation structure and construction method
The invention provides a flexible variable-rigidity circulating water pipe foundation structure and a construction method, the bottom of a circulating water pipe adopts a foundation of a graded broken stone replacing and filling cushion layer, and the foundation comprises a treatment reinforcing area at the joint of the circulating water pipe and an upper beam component of a mechanical tower, and a conventional treatment area at the position, away from the upper beam component of the mechanical tower, of the circulating water pipe; a treatment transition zone between the treatment enhancement zone and the conventional treatment zone; wherein the thickness of the treatment strengthening area is larger than that of the conventional treatment area, the thickness of the transition treatment area is gradually increased from the conventional treatment area to the treatment strengthening area, and the length of the transition treatment area is the ratio of the settlement difference of the transition treatment area to the bending angle of the circulating water pipe of the transition treatment section; differential settlement is well reduced, secondary internal force of a mechanical tower component is reduced, material resources are saved, and the construction cost is reduced.
本发明提供了一种柔性变刚度的循环水管地基结构及施工方法，循环水管底部采用级配碎石换填垫层的地基，所述地基包括：循环水管与机力塔上部梁构件连接处的处理加强区，循环水管远离机力塔上部梁构件位置的常规处理区，处理加强区和常规处理区之间的处理过渡区；其中，处理加强区的厚度大于常规处理区的厚度，过度处理区的厚度自常规处理区向处理加强区逐渐增厚，且过渡处理区的长度为过渡处理区的沉降差与过渡处理段的循环水管弯曲角度的比值；本发明很好地缩小了差异沉降，减少了机力塔构件的次内力，节约了材料资源，降低了工程造价。
