UHPC bent cap gate-type pier suitable for high pier and construction method
The invention discloses a UHPC bent cap portal pier suitable for a high pier and a construction method. A traditional prestressed concrete cover beam door type structure is large in dead weight, and concrete pouring construction has large interference and influence on operation of an existing railway. The device comprises a UHPC cover beam, wherein a swivel pier column is arranged at one end of the UHPC cover beam; a swivel device is arranged at the bottom of the swivel pier column; a fixed pier column is arranged at the other end of the UHPC cover beam, and the UHPC cover beam is connected with the fixed pier column through a fixed pier column upper connecting steel bar sleeve and a fixed pier column lower connecting steel bar sleeve; a connecting steel bar sleeve on the fixed pier column is arranged on the UHPC cover beam; and the fixed pier column lower connecting steel bar sleeve is arranged on the fixed pier column. The problem that the integrality of the prefabricated and assembled bent cap is poor is solved, meanwhile, the problems of safety and hoisting difficulty of bent cap construction under the high pier condition can be avoided, and the influence on existing lines is eliminated.
本发明公开了一种适用于高墩UHPC盖梁门式墩及施工方法。传统预应力混凝土盖梁门式结构自重大、混凝土浇筑施工对既有铁路的运营干扰和影响较大。本发明包括UHPC盖梁，UHPC盖梁一端设置有转体墩柱；转体墩柱底部设置有转体装置；UHPC盖梁另一端设置有固定墩柱，UHPC盖梁与固定墩柱通过固定墩柱上连接钢筋套筒和固定墩柱下连接钢筋套筒连接；固定墩柱上连接钢筋套筒设置于UHPC盖梁上；固定墩柱下连接钢筋套筒设置于固定墩柱上。本发明解决了预制拼装盖梁的整体性较差的问题，同时可以避免高墩情况下盖梁施工的安全和吊装困难的问题，消除对既有线的影响。
