Prefabricated pier column and bearing platform connecting structure and construction method
The invention discloses a prefabricated pier column and bearing platform connecting structure and a construction method. The structure comprises a stand column and a bearing platform, wherein the stand column comprises a section increasing section and a standard section, and the size of the cross section of the section increasing section is larger than that of the standard section; a plurality ofstand column steel bars and corrugated pipes are arranged on the circumference in the stand column and on the circumference in the section increasing section respectively, the corrugated pipes are located between the inner surface of the section increasing section and the stand column steel bars and close to the stand column steel bars, and threaded anchor heads are arranged at the bottom ends, which are close to the bearing platform, of the stand column steel bars; a grouting hole is formed in the lower part of the corrugated pipe, and an upper opening of the corrugated pipe is exposed in airas a grout outlet; inner-layer stirrups and outer-layer stirrups are arranged on the annular outer sides formed by the stand column steel bars and the corrugated pipes respectively; a plurality of pre-buried steel bars are arranged on the circumference in the bearing platform, and the pre-buried steel bars extend out of the bearing platform to be inserted into the corrugated pipes. According to the connecting structure, complex and high-precision prefabrication control requirements are not needed, construction operation is convenient, no special process and equipment requirements exist, and meanwhile, the static force and anti-seismic property of piers can be greatly improved.
本发明公开了一种预制桥墩立柱与承台的连接构造及施工方法，构造包括立柱和承台，立柱包括截面增加段和标准段，截面增加段的横截面尺寸大于标准段；立柱内、截面增加段内的环向一周分别设有若干立柱钢筋、波纹管，波纹管位于截面增加段的内表面与立柱钢筋之间且靠近立柱钢筋，立柱钢筋靠近承台的底端设有螺纹锚头；波纹管下部设有压浆孔，其上口暴露在空气中，作为出浆孔；所有立柱钢筋、波纹管分别形成的环向外侧分别设有内层、外层箍筋；承台内的环向一周设有若干预埋钢筋，且预埋钢筋伸出承台插入波纹管中。本发明的连接构造，无需复杂、高精度的预制控制要求，施工操作方便，没有特殊工艺和设备要求，同时能大大改善桥墩的静力和抗震性能。
