The method interconnect broadband wireless access (BWA) network with optical access broadband network (OAN) through any reference point from reference point T, a, ODN, and V inside OAN. Using the disclosed method can solve issue of interconnection between network of world interaction microwave access (WiMAX) and OAN. The invention provides a developing approach for OAN operation manager to develop WiMAX network. The invention puts forward tight coupling mode and loose coupling mode. In the tight coupling mode, building WiMAX network makes the most of line resources laid by original OAN network so as to avoid additional interconnection wiring and lower cost for building WiMAX network. In the loose coupling mode, WiMAX network and OAN network are already built by two operation managers so that interconnection and intercommunication are carried out between two networks in order to share services and application resources on two networks.

The invention discloses a temporary high-strength walkway plate and a special trolley, wherein angle steel covered edges (1) are arranged on edges at the periphery of the walkway plate; integral reinforcing bars (5) are arranged on walkway plate concrete (8); steel bars (9) are connected between the four corners of the inner side of the angle steel and the concrete, and are welded together with the four corners of the inner side of the angle steel; through holes (2) are formed in two ends of the walkway plate. The special trolley is characterized in that a small cross rod (13), wheels (12), a hook (16), a lock chain (15), a connection part (14), a vertical rod (18) and a secondary keel (21) are arranged on a main keel (10). The temporary high-strength walkway plate and the special trolley are simple and practical; raw materials are conveniently drawn; the temporary high-strength walkway plate can be processed and manufactured by using common materials in the construction site; a temporary road can be quickly and efficiently paved; the special trolley can be used for recycling the walkway plate, so that the resource waste and the environmental pollution are avoided. The temporary high-strength walkway plate and the special trolley are wide in range of application.

The invention provides a construction method of a special-shaped slide way. The construction method solves the laying problem of profiled steel sheets in the special-shaped slide way and ensure that the shape of the special-shaped slide way meets the design requirement. According to the construction method of the special-shaped slide way, the BIM technology is introduced into manufacturing of the special-shaped slide way, the manufacturing precision of profiled steel sheet units is guaranteed, all the profiled steel sheet units are hoisted in place according to a special-shaped slide way model, correct assembling of a special-shaped slide way bottom plate is achieved, therefore the laying problem of profiled steel sheets in the special-shaped slide way is solved, and it is guaranteed that the shape of the special-shaped slide way meets the design requirement.

The invention discloses a submarine cable laying protection device at the position of an offshore wind power jacket foundation and an installation method thereof. The submarine cable laying protection device comprises a first protection sleeve pipe, a second protection sleeve pipe and a third protection sleeve pipe; the third protection sleeve pipe sleeves one end of a submarine cable; the second protection sleeve pipe is formed by a plurality of small assemblies through assembly, wherein the small assemblies are fastened through bolts; the first protection sleeve pipe and the second protection sleeve pipe are fixed on the wind power unit jacket foundation; the other end of the submarine cable penetrates the second protection sleeve pipe and the first protection sleeve pipe in turn from the bottom end of the second protection sleeve pipe to be connected into a tower bottom transformer which is arranged in an offshore wind power unit. According to the submarine cable laying protection device at the position of the offshore wind power jacket foundation and the installation method thereof, the problem of submarine cable laying of the offshore wind power station fan jacket foundation of the offshore and intertidal zone is solved, the construction period is shortened, the construction process is simplified, the construction cost is greatly reduced, and the submarine cable laying process is optimized.
