Prefabricated pipe pier and cast-in-place pile connecting structure and construction method thereof
The invention discloses a prefabricated pipe pier and cast-in-place pile connecting structure and a construction method thereof. A cast-in-place cup-shaped connector is coaxially formed at the upper end of the cast-in-place pile, an embedded section on the lower portion of a prefabricated pipe pier is inserted into a socket hole of the cast-in-place cup-shaped connector, a pipe pier outer side connecting grouting material is poured between the lower end face of the embedded section and the bottom face of the socket hole and between the outer wall of the embedded section and the socket hole, and pipe pier inner side core filling concrete is poured into a hollow hole in the lower portion of the prefabricated pipe pier; and a vertical main rib of the cast-in-place pile extends into the cast-in-place cup-shaped connector, and a longitudinal connecting rib extending into the hollow hole of the prefabricated pipe pier in the longitudinal direction is arranged in the cast-in-place cup-shapedconnector. The vertical main ribs of the cast-in-place pile extend into the cast-in-place cup-shaped connector, and the longitudinal connecting ribs of the cast-in-place cup-shaped connector extend into the hollow hole of the prefabricated pipe pier in the longitudinal direction, so the requirement for the anchoring length of reinforcing steel bars can be lowered, and connection between the pipe pier and the cast-in-place pile is achieved through small work amount and large construction error tolerance.
本发明公开了一种预制管墩与灌注桩连接结构及施工方法，灌注桩的上端同轴形成现浇杯型接口，对应的预制管墩下部的埋置段承插在现浇杯型接口的承插孔中，埋置段的下端面与承插孔的底面之间以及埋置段的外壁与承插孔之间灌注有管墩外侧连接灌浆料，预制管墩下部的中空孔中灌注有管墩内侧填芯混凝土；灌注桩的竖向主筋伸入现浇杯型接口中，现浇杯型接口中设有沿纵向伸入预制管墩的中空孔中的纵向连接筋。本发明中，灌注桩的竖向主筋伸入现浇杯型接口，现浇杯型接口的纵向连接筋沿纵向伸入预制管墩的中空孔中，可以降低钢筋锚固长度要求，实现用较小的工程量和较大的施工误差宽容度实现管墩与灌注桩之间的连接。
