Construction method of light core mold small-section hollow thin-wall high pier
The invention relates to the technical field of hollow thin-wall high pier construction, and discloses a light core mold small-section hollow thin-wall high pier construction method, which comprises the following steps: after bearing platform construction is finished, remeasuring the center line and elevation of a bearing platform, simultaneously releasing a design size contour control point of a hollow pier bottom solid section and a pier center line, and then constructing a hollow core mold according to the control point and the size of each part of a pier body; the method comprises the following steps: taking an ink ejection method and an ejection pier body linear section as a measurement basis of the first construction of the pier mold, after the construction of a first section of pier body is finished, sequentially removing the outer mold, lifting and erecting the outer mold, then removing the inner mold, and lifting and reinforcing the inner mold. According to the construction method for the small-section hollow thin-wall high pier with the light core mold, the mold core is made of light materials, and compared with a traditional rigid and wood detachable inner mold plate, the application of the light core mold overcomes the defects that when a traditional inner mold is operated in a limited space, time and labor are wasted during installation and detachment, the cost is high, the dead weight is large, the working environment of workers is poor, and the construction period is delayed.
本发明涉及空心薄壁高墩施工技术领域，且公开了一种轻质芯模小截面空心薄壁高墩施工方法，承台施工完毕，对承台中线、标高进行复测，同时放出空心墩墩底实体段设计尺寸轮廓控制点及墩中心线，然后根据控制点及墩身各部分尺寸，用弹墨法及弹出墩身直线段作为墩模首次施工的测量依据，带第一节墩身施工完毕后，依次拆除外模，并对外模进行翻升，支立，随后在对内模进行拆除，并对内模进行翻升、加固。该轻质芯模小截面空心薄壁高墩施工方法，通过采用轻型材料制成的模芯，与传统的刚、木等拆卸型内模板相比，轻质芯模的应用解决了传统内模在有限空间作业条件下，安装与拆除费时费力、费用高、自重大、工人工作环境差、耽误工期等缺陷。
