摘要： The installation and use of embedded sacrificial anodes to protect reinforced concrete may be improved. In one example a cavity [2] is formed in the concrete [3] and a puttylike backfill [4] is placed in the cavity and a compact discrete anode comprising a sacrificial metal element [1] is inserted into the backfill and a space is provided into which the backfill may move when subjected to a pressure arising from the formation of voluminous sacrificial metal corrosion products and a high current is passed from the anode to the steel in the concrete to arrest steel corrosion and activate the anode in the backfill. The space may be provided by venting the backfill to space outside the cavity through an opening [5] or by including a void space within the backfill [6] or a void space within the cavity [7].

摘要： A single anode system used in multiple electrochemical treatments to control steel corrosion in concrete comprises a sacrificial metal that is capable of supporting high impressed anode current densities with an impressed current anode connection detail and a porous embedding material containing an electrolyte. Initially current is driven from the sacrificial metal [1] to the steel [10] using a power source [5] converting oxygen and water [14] into hydroxyl ions [15] on the steel and drawing chloride ions [16] into the porous material [2] around the anode such that corroding sites are moved from the steel to the anode restoring steel passivity and activating the anode. Cathodic prevention is then applied. This is preferably sacrificial cathodic prevention that is applied by disconnecting the power source and connecting the activated sacrificial anode directly to the steel.

摘要： The present invention relates to a method of and an apparatus (20) for cathodic protection of reinforced concrete using discrete anodes (22) in or on the reinforced concrete member (14) to improve performance and service life of the discrete anodes. The discrete anode (22) is embedded in a cementitous grout or mortar (24) to encapsulate the anode (22) and provide contact to complete the cathodic protection circuit. A lithium salt is added to the cementitous grout or mortar (24) in an amount of at least about 0.05 gram per cubic centimeter. The lithium salt functions to enhance the performance of the cathodic protection system (20) by minimizing the deleterious effects of the anode reaction products on the grout or mortar adjacent to the anode and increasing the protective current delivered to the reinforcing steel.

摘要： Two-parted ballastblock/counterweight (1) of the known type, round (circular), square as shown on the drawing, hexagonal, octagonal or of any other outer geometrical shape, with imbedded metallic anodes (4) which are to be placed in the immediate vicinity of the metal-bolts (3) which shall be used for attaching and fastening the ballastblocks/counterweights (1) onto a pipeline (2) which pipeline is to be placed on or into the bottom of sea or lake. The imbedded anodes (4) are in this way placed in the longitudinal direction of the bolts (3) and very close to these bolts (3) which bolts the anodes (4) shall protect against corrosion in such a way, that the galvanic field of stress becomes minimal. By forming the anodes (4) as pipes, which are to be imbedded in the ballastblock (1), ensures furthermore, that the long boltholes in the ballastblock (1) becomes straight and formstable. The anodes (4) are on the drawing shown as cylindrical pipes, but they can be made with any other geometrical cross section shape including profiled bars and the like. In the same way these imbedded anodes can be made with any other sectionalizing than that shown on the drawing, for example as bushes or bar-pieces, placed in the long boltholes, eventually directly onto the boltshanks themselves.

摘要： The present invention is a hydraulic excavation and delivery device capable of hydraulically removing soil overburden from a buried structure, like a pipeline, and delivering an article, such as an electro-mechanical connector for attachment to the buried structure. Hydraulic excavation is achieved by directing a stream of fluid at soil adjacent to and inside an open bottom region of the device to simultaneously dislodge adjacent soil, suspend dislodged soil in the accumulating fluid and form a pit that the device may fit within. Delivery of article is achieved by: (1) loading an article into the tool; (2) advancing the device toward the buried structure by deepening the pit without significant failure (slumping or sagging) of the pit walls until a portion of the buried structure is exposed and within the device; (3) landing the device on the exposed portion of the structure; (4) fixing the article to the exposed portion of the structure; and (5) releasing the article from the device.
