This invention relates to an integrated demolition and construction method for rebuilding a suspension bridge on the same site after demolishing an old rigid frame bridge. The method involves first demolishing the old bridge, then constructing the anchorages, main towers, and side spans of the new suspension bridge, installing the main cables and cable-mounted cranes, and using the cable-mounted cranes to dismantle the closure section of the middle span, the side spans, and the cantilever of the main beam of the middle span of the old bridge, and hoisting the steel box girder of the new suspension bridge. Simultaneously, crawler cranes are used to sequentially dismantle the closure section of the side spans, the cast-in-place section of the side spans, and the side piers of the old bridge. This invention allows for overlapping and simultaneous demolition and construction, which helps shorten the construction period. Utilizing the old bridge deck as a traction platform for the pilot cable of the new suspension bridge across the river does not affect navigation and saves costs. Using the cable-mounted cranes from the new suspension bridge construction for demolition ensures high construction efficiency and safety.

This application provides a network closed-loop control method, device, medium, and program product based on tail delay prediction. The method includes: acquiring flow identification information and training semantic context of the target set communication flow during the distributed synchronous training process of artificial intelligence; determining the current path and candidate paths based on the flow identification information and collecting corresponding telemetry data; predicting the tail delay index of the current path and each candidate path within a preset prediction window by combining the training semantic context and telemetry data; evaluating the path based on the tail delay index and path adjustment cost of the candidate paths, using the current path as a comparison benchmark, and determining the target path; adjusting the target set communication flow to the target path when the preset path control conditions are met and the suppression conditions are not hit; and executing hold or back control based on the operational feedback information after path adjustment to update the tail delay prediction process. This application can identify the risk of tail delay degradation of the set communication flow in advance, reducing false triggering and path oscillation.

The utility model relates to sealing structure technical field and disclose a kind of rotary shaft sealing structure of induced draft fan, the sealing structure includes female clamp ring, male clamp ring, and the packing ring that is clamped between male clamp ring and female clamp ring and surrounds and wraps rotary shaft, female clamp ring includes the first sub half ring and second sub half ring of being able to splice or separate, male clamp ring includes the third sub half ring and fourth sub half ring of being able to splice or separate, and the male clamp ring and female clamp ring are detachably connected.Cleverly the male clamp ring and female clamp ring are designed as the sub half ring structure of being able to splice, without removing bearing and unloading rotary shaft when installing, also without reforming to machine case structure, directly splice installation in rotary shaft original position, greatly reduce the workload and time consumption of improvement process, reduce the influence time to the normal operation of equipment.Packing ring is clamped under the male clamp ring and female clamp ring, can be closely fitted rotary shaft, effectively block air leakage point, guarantee induced draft fan long-term stable operation.
