Bearing-socket type prefabricated pier connecting structure and construction method thereof
The invention discloses a bearing-socket type prefabricated pier connecting structure. The structure comprises a prefabricated pier body and a bearing platform, a bearing platform groove is formed inthe bearing platform; a plurality of bearing platform reserved steel bars arranged in the vertical direction are pre-buried in the bearing platform. The prefabricated pier body sequentially comprisesan exposed end, a bearer and an embedding end from top to bottom. The bearer is provided with a plurality of steel bar inserting grooves matched with reserved steel bars of the bearing platform in thecircumferential direction. The free ends of the plurality of bearing platform reserved steel bars are respectively inserted into the steel bar inserting grooves; the outer wall of the embedded end isprovided with a plurality of annularly-protruding stand column shear keys. The embedded end is embedded into the groove of the bearing platform; the lower surface of the bearer is placed on the uppersurface of the bearing platform; grouting materials are poured into the steel bar inserting grooves and the bearing platform grooves. The volume of the grouting material can be adopted to calculate the pouring amount of the grouting material, a gap between the bearing platform and the prefabricated pier body is large, the phenomenon of non-fullness does not exist, splicing construction is easy, the construction error-tolerant rate is high, and the defects that in the prior art, potential safety hazards exist, and the grouting fullness degree is not easy to check can be overcome.
本发明公开了一种承托‑承插式预制桥墩连接结构，包括预制墩身和承台，承台上开设有承台凹槽，承台内预埋有若干沿竖直方向设置的承台预留钢筋，预制墩身从上至下依次包括外露端、承托及嵌入端，承托沿圆周方向开设有与承台预留钢筋相匹配的若干钢筋插槽，若干承台预留钢筋的游离端分别插入钢筋插槽内，嵌入端的外壁设置若干环形凸起的立柱剪力键，嵌入端嵌入承台凹槽内，承托的下表面搁置于承台的上表面上，钢筋插槽内以及承台凹槽内均浇筑有灌浆料，本发明可以采用体积计算灌浆料的浇筑量，且承台与预制墩身之间间隙比较大，不存在不饱满的现象，拼装施工简单，施工容错率高，可以改善现有技术中存在安全隐患、灌浆饱满程度不易检查的缺陷。
