Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0026] Such as Figure 1 to Figure 6 As shown, firstly, the present invention provides a system for resisting horizontal force of a continuous beam flexible pier, including a tension end 1 and an anchor end 2 connected by a steel strand 3 .
[0027] The tension end 1 includes a first anchor seat 12 arranged on the beam section 4 that has been assembled in the rear through the first steel bar 11, and the first anchor seat 12 is provided with a horizontally arranged jack 13;
[0028] The anchoring end 2 includes an anchor plate 21 and a second anchor seat 23 arranged on the section beam 5 at the top of the flexible pier through a second steel bar 22;
[0029] One end of the steel strand 3 passes through the jack 13 through the first anchor base 12 , and the other end is fixed on the second anchor base 23 through the anchor plate 21 .
[0030] Wherein, the first steel...

The invention discloses a system and method for a continuous beam flexible pier to resist horizontal force. The system comprises a tension end, an anchoring end and a steel stranded wire. The tension end comprises a first anchor seat arranged on a spliced beam section at the back through a first steel bar, the first anchor seat is provided with a horizontally arranged jack, the anchoring end comprises an anchor plate and a second anchor seat arranged on a front flexible pier top segment beam through a second steel bar, the tension end is connected with the anchoring end through the steel stranded wire, one end of the steel stranded wire penetrates through the jack through the first anchor seat, and the other end of the steel stranded wire is fixed on the second anchor seat through the anchor plate. According to the system and method for the continuous beam flexible pier to resist the horizontal force, movement and displacement of the flexible pier in the segment beam erecting process can be reduced through an opposite-pull device, and structural safety of a flexible pier body is guaranteed.
Description
technical field [0001] The invention relates to a bridge construction method, in particular to a system and method for a continuous beam flexible pier to resist horizontal force. Background technique [0002] With the advancement of science and technology and the rapid development of bridge construction, bridge construction is increasingly emphasizing prefabrication and industrialization, especially prestressed concrete continuous beams, segmental prefabrication-bridge site cantilever construction methods have been widely used. The cantilevering of the bridge position is carried out hole by hole by the bridge erecting machine. After the assembly of a hole beam is completed, the bridge erecting machine must travel to the next hole beam, but the bridge erecting machine will inevitably be under the bridge erecting machine during the running process. At the same time, the supporting pier body generates a certain horizontal force, the front pier body is subjected to a forward hor...
