Bridge systems and methods for constructing bridges having overhang surfaces employing generally rectangular, precast, prestressed concrete panels. One method includes delivering a plurality of generally rectangular, precast, prestressed concrete panels to an installation site, and delivering one or more support beams to the installation site, each support beam having a support and a base. The concrete panels are positioned on the supports of the one or more support beams with an overhang panel section and a traffic panel section. The concrete panels are then connected to the support beams by positioning steel reinforcement in block outs or voids, pouring unsolidified concrete into the voids, and curing the unsolidified concrete to form an overhang traffic surface. Bridges constructed employing the precast, prestressed concrete panels and methods. Other bridge systems employ prestressed concrete L-walls and double-T members, where weight-bearing L-walls have pockets for webs of the double-T members.

A bridge overhang bracket assembly includes a top member, a diagonal member and a side member. The top and diagonal members are pivotally attached proximate to respective outer and upper ends thereof. The top and side members are pivotally attached proximate to respective inner and top ends thereof. The diagonal and side members are pivotally attached proximate to respective lower and bottom ends thereof. The side member is configured so that its length between the bottom and top ends is adjustable.

An elongated girder for use in a bridge includes a girder body having a modified V-shaped cross section. The body includes longitudinally extending webs defining sides of the girder, a bottom flange extending between the webs, and top flanges extending outwardly from the webs.

A corrugated pipe connection device for a continuous section at the top of a continuous T-shaped beam bridge pier. The connection device includes a combined steel pipe telescopic device and a corrugated pipe connector, the interiors being hollow; the connector includes a first clamping member for clamping a wall surface of a corrugated pipe; one end of the telescopic device is a second clamping member with the same structure as the first; the other end is a telescopic steel pipe which is telescopic in the length direction; and the telescopic steel pipe is connected to the connector. The device replaces a corrugated pipe between two T-shaped beams, thereby avoiding problems such as breakage and slurry leakage caused by an original construction mode. The device can stretch out and draw back according to a distance between the T-shaped beams, and steel strands can be stranded by means of a stranding machine.

A method for installing a prestressing element in an anchor block, in which the prestressing element is attached to a holder, includes the holder being moved to the anchor block, the prestressing element being introduced into a through-opening of the anchor block, and the prestressing element being fixed to the anchor block. The holder can be attached to the prestressing element at a distance which is selected so that the length of the projection of the prestressing element on the side of the holder facing the anchor block is greater than the length of a portion of the prestressing element, which is required for introducing the prestressing element into the through-opening and fixing the prestressing element to the anchor block. A holder for carrying out the method is also disclosed.
