405011000 | MEANS TO EXPOSE A NORMALLY WETTED SURFACE,E.G., COFFERDAM, ETC. | 9 |
20100067986 | ADJUSTABLE SYSTEM AND METHOD FOR CARRYING OUT WORK AT AN UNDERWATER STRUCTURE - The present invention relates to a dry setting installation ( | 03-18-2010 |
20140119830 | MOBILE DRY SETTING ELEMENT AND INSTALLATION, PROCESS FOR USING SAME AND USE THEREOF - A dry setting installation for generating a substantially dry working space for carrying out work on part of a partially submerged structure, the dry setting installation comprising a truncated elongated angular-, oval-shaped or part-angular-part-oval-dry setting element, which with the part of a partially submerged structure is capable of forming a cofferdam round the part of the partially submerged structure; and a process for the treatment of part of a partially submerged structure, the process comprising the steps of: closing the dry setting element with the part of the partially submerged structure, sealing the dry setting element on the part of the partially submerged structure; pumping out the water thereby providing a cofferdam round the part of the partially submerged structure; cleaning the surface of the part of the partially submerged structure; curing the curable adhesive coating, filling the dry setting installation with water, removing the dry setting element. | 05-01-2014 |
405012000 | Contoured to wetted surface, e.g., side hung ship caisson | 1 |
20130294835 | MOBILE DRY SETTING ELEMENT AND INSTALLATION, PROCESS FOR USING SAME AND USE THEREOF - A truncated elongated oval-shaped dry setting element having two truncated elongated oval-shaped ends one of which is open and the other submergible end is closed by a floor accommodating a U-shaped receiving collar, the opening between the ends of said truncated elongated oval-shaped dry setting element and the width of the U-shaped receiving collar being sufficient to accommodate a partially submerged isolated structure such that said U-shaped receiving collar is sealable under water against said isolated structure with a collar sealing element closing the U of said collar in the plane of the collar with said isolated structure in place, and the opening between the ends of the first truncated elongated oval-shaped dry setting element being closable with a closure, wherein said dry setting element comprises a U-shaped structure replicating the opening formed by said U-shaped receiving collar at a sufficient distance from said U-shaped receiving collar so as to receive said isolated structure without substantially reducing said dry working space and such that when secured in said U-shaped structure there is substantially no movement of the dry setting installation relative to said isolated structure once said isolated structure is in place; a dry setting installation ( | 11-07-2013 |
405013000 | Having transport, placement, or dislodgement means | 1 |
20160138239 | CAISSON - A caisson for marine works particularly intended for use in vertical dikes which is formed by a plurality of segments ( | 05-19-2016 |
405014000 | Connectable sections | 5 |
20100189503 | Coffer dam for servicing marine structures - A coffer dam for use in maintenance and repair of support pylons for marine structures such as piers, wharfs, and drilling platforms. Insulated bottom, side walls and roof members form an enclosure that can be heated, or cooled, to provide a good work environment and can protect against undesirable condensation that could adversely effect chemicals and coating materials. A grated floor member allows for debris to be collected and a vacuum system is used for proper disposal, and an improved seal protects against water leaking into the enclosure. | 07-29-2010 |
20100232878 | Universal Framed Cofferdam - Universal Framed Cofferdam has prefabricated skeletal steel space framing formed from multiple steel vertical pipes and two levels of horizontal diaphragm trusses rigidly connected to pipe columns. Beams of each diaphragm truss are attached to vertical pipes of the framing with rigid moment connections creating a rigid space frame of the perfectly round form that is used as a false work of the Cofferdam. Wales of the Cofferdam and short pieces of the flat sheet piling are attached to the vertical pipes forming a skeleton of the Cellular structure. The Skeleton of the Universal Framed Cofferdam is prefabricated in the convenience of the Dry Dock and than floated to the site. Buoyancy of the framing allows Cofferdam skeleton transportation without using the barge or otherwise necessary floating devices. Once brought to the site of installation Cofferdam skeleton is installed vertically in position and leveled on the bottom of the river bed. If necessary river silt can be jetted and pumped out of pipe annular space and pipe columns of framing can be simultaneously lowered in position by using vibro—hummer. After space framing installation, rock sockets are predrilled through the annular space of vertical pipes and rock anchors installed. Sheet pile skin of the Cofferdam installed between pipe columns concludes Cofferdam Can erection. Universal Framed Cofferdam Can than filled with compacted gravel and becomes a Hybrid Gravity Caisson/Columnar water front or marine structure that has the best features of the Conventional Cellular Cofferdam and of Columnar Dolphin structure. It has enhanced sliding and overturning stability provided by Rock anchors preloaded by Cofferdam granular fill and has effective mechanism that prevents concave or convex surface of rupture failure that may be suffered by conventional Cellular Cofferdams, and has mechanism that more effectively resists deep surface sliding failure of the Cofferdam base. | 09-16-2010 |
20110064520 | DEVICE FOR PREVENTING ICE FORMATION ON A SURFACE LAYER - The invention is concerned with an arrangement for preventing weather-induced formation of ice to a top surface ( | 03-17-2011 |
20120224920 | COFFERDAM MODULES - A cofferdam module can include first and second side panels, outer support members that are each coupled to the outer side of one of the side panels, and two different types of inner support members that are each coupled to the inner side of each of the side panels. | 09-06-2012 |
20140112718 | Universal cellular cofferdam with embedded columnar framing and embedded rock anchor mechanism - One embodiment of Universal Cellular Cofferdam with embedded prefabricated columnar framing ( | 04-24-2014 |
