| Number | Title | Issue Date |
| 7226247 | Method and apparatus for creating soil or rock subsurface support A subsurface support includes a protective outer member that encases an interior support member. The inner support member may typically be a steel or iron rod which is held within the outer tube as by grout or cement. The outer tube is preferably emplaced by forcing... | 06/05/2007 |
| 7017219 | Dismountable bridge A dismountable bridge, having two track carriers which, viewed in the longitudinal direction of the bridge, are divided into several identical modules, in which case the two track carriers are each spanned by a vault and are suspended at the latter. The vaults are d... | 03/28/2006 |
| 6745421 | Abutment with seismic restraints An abutment especially adapted for use with a bridge is provided which incorporates lateral containment elements which prevent undesirable lateral shifting or movement of the bridge during a seismic event. The lateral containment elements are constructed of varying ... | 06/08/2004 |
| 6682259 | Structure having an insulated support assembly A structure for supporting a road along a road axis over an underpass space spanned by the structure. The structure includes two footings underlying the road with each support assembly being securely mounted to the earth. The structure also includes an ar... | 01/27/2004 |
| 6243994 | Joint for pre-cast concrete twin-leaf arch sections A joint for pre-cast concrete twin-leaf arch sections is self-aligning when the two arch sections are initially brought into abutting contact with each other. The joint provides a rigid connection between the twin units and is achieved on site by means of... | 06/12/2001 |
| 6234716 | Underground structural work including prefabricated elements associated with piles and a process for its production An underground structural work, particularly for forming tunnels, underpasses, carparks or the like, includes a pair of containment structures which extend along two opposite sides of the work. These structures include pile elements capable of carrying a ... | 05/22/2001 |
| 6205605 | Method of construction of a vault, bearing piece and half-shell for construction of the vault Method of construction of a vault, in which at least two half-shells (1-8; 60) are brought to bear against one another by means of at least two bearing pieces (30, 50; 70) which are mated and, each half-shell (1-8; 60) comprising an upper edge (21; 61) an... | 03/27/2001 |
| 6018834 | Method for building a bridge and bridge built according to said method Method for building bridges and bridge built according to the method especially a girder bridge with one, two or more girders or longitudinal beams resting on supports at abutments or the like. The novelty lies therein that the girder or longitudinal beam... | 02/01/2000 |
| 5549418 | Expanded polystyrene lightweight fill The present invention includes a structure formed on an earthen surface. The structure includes an abutment, a bridge, a plurality of foam blocks, and a pavement structure. The abutment is constructed on the earthen surface. The abutment and the earthen s... | 08/27/1996 |
| 4564967 | Bridge abutment The invention provides a stabilized earth bridge abutment comprising a compacted earth mass containing reinforcing members therein to stabilize the mass, there being provided, in contact with said mass and close to a substantially vertical surface thereof... | 01/21/1986 |
| 4051570 | Road bridge construction with precast concrete modules Precast concrete footings, stretchers, road slabs, and curbing in conveniently transportable sizes are used to construct road bridges and supporting abutments with a minimum of heavy equipment at the construction site. Each stretcher module comprises an e... | 10/04/1977 |
| 3981038 | Bridge and abutment therefor A bridge construction is disclosed in which the ends of a bridge deck are supported by an abutment comprising a mass of internally stabilized earth. A plurality of elongate reinforcing members are arranged in vertically spaced horizontal layers. Within ea... | 09/21/1976 |
