Pier column embedded bar fixing method based on cofferdam stand column
The invention provides a pier column embedded bar fixing method based on cofferdam stand columns. The pier column embedded bar fixing method comprises the following steps that a plurality of steel casings are inserted into a cofferdam area at intervals for drilling pile construction; a plurality of steel sheet piles are inserted into the boundary of the cofferdam area, and the cofferdam area is excavated to a first preset depth; a ring beam is arranged on the inner circumference of the cofferdam area, and a plurality of inner supports are arranged; continuously excavating to the bottom surface of the preset bearing platform in the cofferdam area, and constructing a layer of thick cushion layer; bearing platform steel bars are bound on the thick cushion layer, a bearing platform formwork is built, a pier column embedded bar fixing frame is installed on the periphery of the preset pier column area, and pier column embedded bars are bound in the preset pier column area; and the bearing platform is poured, and the ring beam and the inner support are dismantled after pouring is completed. The method has the advantages that the cofferdam stand column is rooted in the drilled pile, the stability is high, the inner support can be effectively supported in the vertical direction, and the pier column embedded bar fixing frame can effectively fix the pier column embedded bars so as to prevent the pier column embedded bars from being disturbed in the bearing platform pouring process.
本发明提供一种基于围堰立柱的墩柱预埋筋固定方法，该方法包括以下步骤：在围堰区域内间隔插入若干钢护筒进行钻孔桩施工；在围堰区域的边界插入若干钢板桩，并在围堰区域内开挖至第一预设深度；在围堰区域的内周设置圈梁，并设置若干内支撑；在围堰区域内继续开挖至预设承台底面，并施工一层厚垫层；在厚垫层上绑扎承台钢筋并搭建承台模板，在预设墩柱区域外围安装墩柱预埋筋固定架，并在预设墩柱区域内绑扎墩柱预埋筋；浇筑承台，浇筑完成后拆除圈梁以及所述内支撑。本发明的优点是：围堰立柱根植于钻孔桩内，稳定性高，可对内支撑形成竖向有效支撑，墩柱预埋筋固定架可以有效固定墩柱预埋筋以避免在承台浇筑过程中被扰动。
