| The invention relates to a method and installation for constructing an expressway, and to an expressway to be used as a duplicating road for existing urban or suburban motorways assigned for a heavy traffic. The invention object consists in providing enhanced technological capabilities of a mobile installation by construction of an expressway in close quarters, without a decrease in traffic intensity; also consists in construction of an expressway erected above an existing trunk road, mainly along its longitudinal axis, in the course of construction of which expressway any hindrances to traffic on an existing road do not occur. Said object is accomplished by providing a method for constructing an expressway in the form of an elevated road whose length extends at least partly above an existing motorway; which method comprises the steps of: implementation of a foundation portion of load-bearing supports, erection of the load-bearing supports on the foundation portion, placement of girders on the load-bearing supports and mounting of a span structure; erection of the load-bearing supports on the foundation portion being done when at least a portion of the technological equipment to be used for the works is arranged at the level of the upper load-bearing working surface of a gantry-type mobile installation, which installation is preferably self-propelled and consists, for example, of sections disposed in-series along its length; the mobile supports of said installation being disposed within the allocated land lot of an existing motorway; the girders being mounted on the load-bearing supports with at least one hoisting mechanism used as the technological equipment; said hoisting mechanism being preferably of the mobile crane type disposed at least on one section of the gantry-type mobile installation; height of clearance under said installation, in its operation position, being sufficient for allowing traffic on the existing motorway; at least a part of the technological operations for constructing the expressway being carried out such that traffic on the existing road may proceed. A portion of the technological equipment for constructing at least the foundation portion of the load-bearing supports being disposed at the existing motorway level.

| 265 | Method of constructing partially earth-anchored cable-stayed bridge using thermal prestressing technique | US11372124 | 2006-03-10 | US20060200920A1 | 2006-09-14 | Sang-hyo Kim |
| Disclosed is a method of constructing partially earth-anchored cable-stayed bridges using a thermal prestressing technique, in which, when a steel girder-type partially earth-anchored cable-stayed bridge is built using a cantilever construction technique, the center of an intermediate span of the bridge is closed with a final key segment using a thermal prestressing technique, thus applying an initial axial tensile force to reinforcing girders of the bridge. To apply the initial axial tensile force to the reinforcing girders while the center of the intermediate span is closed with the final key segment, an appropriate space length required for closure of the final key segment is determined, and both the heating region and the heating temperature of the reinforcing girders according to the initial axial tensile force to be applied to the reinforcing girders during a process of manufacturing the final key segment are determined. Thereafter, the reinforcing girders are heated using a heating means according to the above-determined conditions, thus being thermally lengthened to predetermined lengths corresponding to the predetermined space length. The junction between the reinforcing girders at the center of the intermediate span is closed with the final key segment and, thereafter, the heating means is removed from the reinforcing girders. | ||||||

| The prefabricated, prestressed bridge system comprises one or more prefabricated, prestressed bridge modules. Each module includes one or more steel beams arranged in a first direction on three or more supporting formwork elements that are arranged in a second direction generally perpendicular to the first direction. Rebar runs through the steel beams in a direction perpendicular to the steel beams and above at least two of the supporting formwork elements. Concrete material is poured to form concrete diaphragms on top of and around the rebar at locations above the supporting formwork elements. After the diaphragms are poured, one or more of the supporting formwork elements are adjusted to stress the steel beams. A concrete deck is fabricated over the surface atop the diaphragms and the steel beams such that the resulting compression stress of the concrete deck secures in place the stresses imparted to the steel beams. | ||||||

| A method for assembly of a stay includes a series of steps that include connecting in the vicinity of an anchoring zone, a new group of N reinforcements to a shuttle located within the sheath of a stay to be installed. The shuttle is driven towards another anchoring zone by means of driving and guiding means. When the shuttle has arrived substantially in the vicinity of the anchoring zone, and as long as entangling is detected between the driving and guiding means in a portion contained substantially between the shuttle and the first anchoring zone, the shuttle is rotated about its main axis in the opposite direction to the said entangling. The group of N reinforcements is then separated from the shuttle. Each reinforcement of the group is tensioned between the anchoring zones. The preceding steps are repeated until the installation of the reinforcements is completed. | ||||||

| 280 | Precast concrete bridge structure and associated rapid assembly methods | US408457 | 1995-03-22 | US5771518A | 1998-06-30 | Michael Lee Roberts |
| A pier and beam bridge structure is formed essentially entirely from steel reinforced, precast concrete elements including elongated, hollow tubular pier members, pier collars, pier base and cap beams, deck beams, deck slabs and side railing members. In forming the support pier structures, the pier members are inserted into dry-drilled pier base excavations through opposite end openings formed in the ground-supported base beams, and are outwardly circumscribed by the collars which are received at their opposite ends in the base beam end openings and openings in the cap beams which are supported at the upper pier ends. A loose aggregate material is dumped into the pier member interiors, and the annular collar and excavation spaces surrounding the pier members. Polymer concrete is then forced downwardly through the pier member interiors, and upwardly through these annular spaces, and cures in a matter of minutes to complete the fabrication of each pier structure. The precast deck beams, deck slabs and railing members are then sequentially installed and rapidly interconnected using hollow connecting pin members inserted into aligned openings formed in abutting concrete surfaces and grouted into place using a quick-setting polymer concrete. | ||||||
