The application discloses a device and method for removing offshore wind power steel pipe piles under deep water conditions, which comprises a supporting device and a counterforce device, a hydraulic jack is installed between the supporting device and the counterforce device, the supporting device is used for providing jacking support force for the hydraulic jack, and the counterforce device is used for providing jacking counterforce for the hydraulic jack after being fixedly connected with a steel pipe pile to be removed. The device is simple in structure, does not need to use a high-pressure system during construction, greatly reduces construction difficulty, has little influence of the environment on construction during construction, does not need to consider the influence of the rising and falling tides on construction during the whole construction process, is convenient for construction progress management and control, and can greatly shorten the construction period.

The utility model relates to a kind of supporting structures, belong to building construction technology field, specifically a structure unilateral supporting structure, including being set in inclined throw support foundation of first pouring bottom plate upper, the inclined throw support foundation is provided with lattice column inclined throw support, the lattice column inclined throw support covers on reserved island, still include the column top embedded plate being set in the top of lattice column inclined throw support, the top of lattice column inclined throw support is connected with public wall by column top embedded plate;Column bottom embedded plate being set in the bottom of lattice column inclined throw support, the bottom of lattice column inclined throw support is connected with inclined throw support foundation by column bottom embedded plate;The utility model has the advantages of convenient construction, effectively avoid the deformation of existing structure, little influence to new structure construction, construction period is short etc.;Solved the problem of not affecting new structure and existing structure to carry out structure connection while unilateral earthwork excavation is ensured that existing structure does not occur serious displacement in existing structure side, public outer wall.

The invention discloses an operation station anti-floating reinforcing structure and a construction method, and belongs to the technical field of underground engineering. The structure comprises a construction fence, a retention wall, a station side wall with a breaking range, a fender post structure, a permanent and temporary combined anti-floating component, a rubber water stop strip and an I-steel temporary support, and a reinforcement cage of the permanent and temporary combined anti-floating component is connected with a fender post main reinforcement and a main body structure side wall reinforcement in an anchoring manner to form a cooperatively stressed anti-floating system; the method comprises the steps that a construction fence and a retention wall are arranged; grouting pipes are driven to stop water, holes are explored and dug for verification, station side walls are broken in a bin-by-bin and segmented mode, and I-shaped steel is erected; a rubber water stop strip is plugged in; and a fender post structure is broken, a reinforcement cage is bound, concrete is poured, and construction is completed. Reliable connection is established between the station main body structure and the enclosure structure, and the floating risk caused by underground water rising is reduced; construction in the station in the whole process reduces the influence of earth surface enclosure and traffic relief, and reduces the influence on pipelines at the top of the station.
