An apparatus and method for reinforcement of partially submerged structural elements such as piles, posts, pillars, and pipes are disclosed. The apparatus includes an upper unit which may be fixed to the structural element above the waterline and a lower unit which is suspended from the upper unit via cables or other support members. The apparatus enables a reinforcing sleeve structure to be constructed in multiple segmented layers from above the waterline which the sleeve structure is lowered beneath the waterline. The lower unit guides the lower end of the sleeve structure down around the submerged portion of the structural element and supports the weight of the sleeve structure until it is fixed in place and filled with concrete or another reinforcing core filler material.

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 multicomponent bridge support system includes: a base portion configured to make contact with bearing soil/strata/bedrock; a support portion configured to engage a bridge deck; and one or more precast intermediate portions configured to space the support portion with respect to the base portion.

Provided is a support structure and a method for manufacture thereof. The support structure, in one aspect, includes first and second expanded metal structural pillars positioned within the ground by a distance (d.sub.1), the first and second expanded metal structural pillars comprising a metal that has expanded in response to hydrolysis. In at least one other aspect, the support structure includes one or more beams spanning the first and second expanded metal structural pillars.

An intelligent integrated anti-collision system and method for a pier, including: a radar sensing device disposed at the joint between the pier and a girder, image collection devices disposed around the pier, control system, hydraulic system and execution device, where the radar sensing and image collection devices transmit collected signals to the control system, which uses the hydraulic system to control the action of the execution device; the execution device is disposed at a middle part of the pier and includes a plurality of sections of steel-reinforced rubber concrete girder connected end to end through pulleys, the hydraulic system can drive the pulleys to rotate to enable the sections to be located on the same horizontal line, and an energy dissipation apparatus is disposed at the tail end of the last section to realize energy dissipation of the energy generated by impact when an object impacts the energy dissipation apparatus.

A single-use or multi-use prefabricated pier top form for topping a concrete pier comprises a hollow mold with an upper portion in the desired shape of the finished pier top, a stepped-down tapered mid portion, and a lower mating portion for mating with the pier form so that concrete can be continuously poured to fill both the pier form and the pier top form at one time. Use of the prefabricated pier top form results in substantial time and material savings because the top of the pier residing above ground can be formed at the same time as the footer and pier are formed replacing the need to form a separate pier top after the pier and footer have been filled with concrete.
