Further, described ground bolt adopts the high tensile reinforcement of tensile strength 900-950Mpa.
Simultaneously, the present invention also provides the construction method of corresponding a kind of vertical prestressing steel-concrete compound rigid frame bridge, it comprises the following steps:, and (1) builds two bridge piers, and on bridge pier pre-buried ground bolt, ground bolt vertically arranges and protrudes upward bridge pier upper surface; (2) on bridge pier, be positioned at the inner side erection support of ground bolt; (3) between two bridge piers, be horizontally set with the girder steel be positioned at above bearing, and make ground bolt upper end through the bolt hole of girder steel end; (4) ground bolt upper end is locked by the anchor nut be positioned on the upside of girder steel to apply vertical pretightning force; (5) on girder steel and the junction concreting of girder steel and bridge pier.
Compared with prior art, the present invention has following beneficial effect: this vertical prestressing steel-concrete compound rigid frame bridge simplify construction, saved space, be conducive to constructing in adverse circumstances; In addition, effectively can produce the pre-flexure stress to girder steel to ground bolt applying vertical prestressing, save cost, improve ride quality and also there is good anti-seismic performance.
