A temporary support system for a road bridge pre-fabricated small box girder-type concealed bent cap, and a method of constructing same. The support system comprises a main beam, a main pier support system, and a lateral pier support system; the main beam is arranged on the transverse side of road bridge piers; the main pier support system is disposed on the transverse side of a main pier area and is located under the main beam; the lower end of the main pier support system is fixed to a main pier bearing platform, whereas the upper end is fixed to the main beam; the lateral pier support system is disposed on the transverse side of a lateral pier area and is located below the main beam; and the lower end of the lateral pier support system is fixed to a lateral pier bearing platform, whereas the upper end is fixed to the main beam.

An installation method of a bent cap for mutually restraining adjacent pier studs in a prefabricated and assembled bridge is provided. A bent cap mold base is configured in a form of a bent cap, which includes fixedly arranging limiting steel rings at two ends of a rectangular frame and vertically arranging steel bar sleeves in the limiting steel rings, hoisting the cap bent mold base on top portions of adjacent two prefabricated pier studs, such that pier stud pre-embedded steel bars protruding from the top portions of the two prefabricated pier studs are correspondingly inserted into the steel bar sleeves at two ends of the bent cap mold base one by one, and limiting the adjacent two prefabricated pier studs in the bent cap mold base.

A boardwalk system including a plurality of treads, each tread including a plurality of grooves extending entirely or substantially entirely thereacross in a transverse direction, wherein each tread is made of concrete. The system further includes a plurality of bases, each base being supported on a ground surface and positioned below each tread at or adjacent to a corner of the associated tread.

An elevated roadway for autonomous vehicles may include a pylon extending vertically from a ground anchor and comprising a metal tube defining a central cavity and a concrete column within the central cavity. The elevated roadway further includes a bracket coupled to the pylon and comprising a mounting plate secured to the pylon and a cantilevered road support member extending from the mounting plate. The elevated roadway may further include a cantilevered road section coupled to the pylon via the cantilevered road support member and comprising a joist structure structurally coupled to the cantilevered road support member, a road member above the joist structure and supported by the joist structure, and first and second side barriers along first and second sides of the road member, respectively. The road member may be adapted to receive a four-wheeled roadway vehicle.

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.

The present devices and methods provide an adjustable foundation support that rests upon the top end of a pier driven to load bearing strata, and is configured to receive a jack within the bracket of the adjustable foundation support to adjust the height of the foundation by the jack pushing down upon the pier through the pier cap and pushing upwards upon the bracket. The foundation can be adjusted by the adjustable foundation support to provide a level foundation, either alone or in cooperation with one or more additional adjustable foundation supports. Once foundation has been adjusted to the required height, the height adjustment lock is engaged to the pier cap to support the weight of the foundation through the bracket, to maintain the required height for the service life of the adjustable foundation support, with the ability to readjust the height, should that be required in the future.

A formwork system, including a plurality of side formwork elements configured to confront a concrete structure, a horizontal formwork panel configured to support the concrete structure, and at least one working platform, wherein the system is configured to be split in a longitudinal direction and stricken or cycled from the concrete structure in two discrete parts.
