Mounting method of bridge prestressed porous anchorage device

The invention discloses a mounting method of a bridge prestressed porous anchorage device. The mounting method includes the steps that working anchors are installed, the working anchors are moved to required positions of the design, and then clamping pieces are used for locking the working anchors and steel strands; the steel strands are separated and carded through a deconcentrator, after the angles of hole channels of limiting plates are adjusted, the steel strands penetrate through the hole channels one by one, the deconcentrator is removed, and the limiting plates are moved to the requiredpositions of the design; all the steel strands penetrate into jacks, and the jacks are moved to the required positions of the design; and the steel strands are separated and carded through the deconcentrator, after the steel strands penetrate through hole channels of the working anchors, the deconcentrator is removed, and after the working anchors are moved to the required positions of the design, the working anchors and
