摘要： A construction method for reinforcing and repairing a steel pipe pile for offshore wind power includes the following steps. Installing multiple support ribs on an outer wall of a steel pipe pile to be repaired along a circumferential direction. Placing multiple support plate components on the support ribs and performing splicing along the outer wall of the steel pipe pile to form an annular support plate assembly. Installing multiple hoop cylinder components on the support plate assembly, performing splicing along the outer wall of the steel pipe pile to form an annular hoop cylinder assembly, and forming a grouting cavity between the hoop cylinder assembly and the steel pipe pile. Connecting grouting pipelines to grouting ports of the hoop cylinder assembly, and performing a grouting operation. After grouting, forming a reinforcement and repair structure on the outer wall of the steel pipe pile when grouting materials are solidified.

摘要： A foundation extension procedure is disclosed, of the type used in the extension of large structures, and especially its use in the reinforcement of existing wind turbine farms, founded in the earth, which uses an overlaid beams structure on the existing foundation and bonded to it, supported by new, smaller peripheral foundations, creating a new foundation capable of supporting a larger structure, which uses the old foundation as ballast. The main advantage of this procedure is that it allows a quick and economical installation, minimizing the environmental impact, reusing both the existing foundation and most of the complementary infrastructures in the case of wind turbines, achieving a new, larger and stronger foundation, completely integrated in the environment.

摘要： Disclosed is a method for strengthening and lifting a high-rise building that has a raft foundation, comprising: arranging a plurality of measuring points at intervals around the outer contour of a building, and determining the side to be lifted of the building according to the elevation of the measuring points; distributing a plurality of reinforcement grouting holes perpendicular to a raft foundation at intervals within the range of the raft foundation, and using pressure grouting in the reinforcement grouting holes to form a reinforcement under the raft foundation; laying downwardly inclined lifting holes on the outer side of the raft foundation at two ends close to the side to be lifted of the building; and performing simultaneous pressure grouting in the lifting holes to lift the side to be lifted of the building.

摘要： The method of installing the mastic footprint may be used as a repair or in connection with a new installation of the structure. The method produces a mastic footprint that is resistant to infiltration of water, fuel, and salt, including mixtures thereof. The method further produces a mastic footprint that is thermally resistant. In repairs, the mastic footprint of the method provides longevity of use of at least one year and up to 5 years prior to any repair or replacement. In new installations, the mastic footprint provides longevity of use of at least 1 year and up to 15 years prior to any repair or replacement. Finally, the method of installing a mastic footprint does not affect the structural integrity of the adjacent or surrounding surface material, where the adjacent or surrounding surface material does not require repair or replacement sooner than if the method had not been deployed.

摘要： A method for repairing a wind turbine tower foundation, wherein the method comprises steps of
providing a hardening liquid comprising functionalized graphene, wherein the hardening liquid has density above water or salt water;
introducing the hardening liquid to the wind turbine tower foundation, thereby displacing the water or salt water due to higher density of the hardening liquid;
hardening the hardening liquid by resistive heating.-

摘要： A locking track for a wall reinforcement system comprises a top panel, two opposing side panels, a channel defined between the top panel and the two opposing side panels, and locking tabs formed in the two opposing side panels and extending into the channel. The wall reinforcement system further comprises a post. The post comprises a web, two flanges extending transversely from the web, and at least one slot formed in each one of the two flanges. The post is attachable to the locking track, and when attached, the at least one slot formed in each one of the two flanges receives a corresponding one of the locking tabs to lock the post to the locking track.

摘要： Methods and systems are disclosed to transfer forces on a damaged pile to the lower part of the pile, bypassing the damaged area. Rings of various materials are tightly wrapped around the pile or clamps are attached to the pile, above and below the damaged area, causing calculated friction between the pile and the rings and/or clamps. Subsequently the damaged area and the rings and/or clamps are encased in a curable substance, such as concrete. After curing, the rings and/or clamps above the damaged area will receive the stresses on the pile through the friction with the pile and will transfer them to the concrete which in turn will transfer the stresses to the lower part of the pile through the lower rings and/or clamps and their friction with the lower part of the pile. Nothing is welded to the pile and the pile is not altered in any way.

摘要： A cutting tool adapter for creating an underpinning structure and method of creating the underpinning structure are provided. In some examples, the cutting tool adapter may connect a cutting tool to a working machine arm to enable the cutting tool to cut and dislodge soil below an existing foundation or structure. As the soil is cut and dislodged, it is mechanical mixed with an additive, such as a cementitious material, via the cutting tool. The mixed soil and additive may then harden in the area below the existing structure or foundation to create an underpinning structure to provide additional support for the existing structure or foundation.

摘要： Methods are provided for repairing an existing structure to cover at least a portion of the existing structure with a repair structure. Such methods comprise mounting one or more standoff retainers to the existing structure; coupling one or more standoffs to the standoff retainers such that the standoffs extend away from the existing structure; coupling one or more cladding panels to the standoffs such that the panels are spaced apart from the structure to provide a space therebetween; and introducing a curable material to the space between the panels and the existing structure, the panels acting as at least a portion of a formwork for containing the curable material until the curable material cures to provide a repair structure cladded, at least in part, by the panels. Corresponding apparatus for effecting such methods are also provided.
