The invention relates to a partition plate welding method, and belongs to the technical field of welding. The outer ring plate, the inner ring plate and the blades are assembled; performing shrinkage fit on the positioning sleeve; welding is conducted; welding a cover plate; welding a radial steam seal body; heat treatment; removing the cover plate and the positioning sleeve; the partition plate is separated along the split surface; surfacing is conducted on the split; post-heat treatment and the like. The two semicircular partition plates are welded after being spliced into a whole, the integrity of the manufactured partition plate is better, error accumulation caused by respective welding is avoided, and the partition plate has higher matching precision after being installed in a steam turbine. The two semicircular outer ring plate bodies are positioned through the positioning sleeve, so that the outer ring plate bodies are tightly spliced into a whole, the integrity is better, and the outer ring plates are not prone to deformation in the welding process. When the radial steam seal ring is welded, the blades are completely covered by the cover plate, so that welding slag is effectively prevented from splashing to the surfaces of the blades to cause damage to the blades.

The utility model discloses a UHPC (Ultra High Performance Concrete)-based hollow slab bridge grading and reinforcing structure which comprises hollow slabs which are transversely arranged at intervals, the integrated pavement layer is arranged at the upper end of the hollow slab; the plate bottom reinforcing layer is arranged at the lower end of the hollow plate; the bridge deck slab reinforcing mesh is embedded in the integrated pavement layer; the plate bottom reinforcing layer reinforcing mesh is embedded in the plate bottom reinforcing layer; the upper end of the integral connecting steel bar is connected with the bridge floor steel bar mesh, and the lower end of the integral connecting steel bar is connected with the plate bottom reinforcing layer steel bar mesh; one end of the twisted steel located at the lower end of the hollow slab is connected with the hollow slab, and the other end of the twisted steel located at the upper end of the hollow slab is connected with the slab bottom reinforcing layer reinforcing mesh; wherein the template structure is poured and filled by UHPC (Ultra High Performance Concrete). The fabricated hollow slab bridge has the advantages of effectively improving the anti-bending bearing capacity, the structural safety and the durability of the fabricated hollow slab bridge.

The present invention provides a ring and a production process thereof, comprising a body, a fixing part and a diamond, wherein the body is a ring-shaped structure for being put on a finger, and the projection view of the outline of the body is in the shape of a water drop. The ring and the production process thereof provided by the present invention use the fixing part and the body to enclose a containing space, and the diamond is placed in the containing space, and the diamond is only limited by the limiting point without bonding or inlaying, so that the diamond does not need to be fixed by traditional processes, and the perfect connection between the diamond and the precious metal is achieved, and the volume of the containing space is larger than the volume of the diamond, so that the diamond can rotate and / or slide freely in the containing space, which is convenient for cleaning or replacing the diamond, and can display the diamond at multiple angles by rotating or sliding, highlighting the spirituality and dynamics, enhancing the three-dimensional beauty of the whole ornament, and further highlighting the three-dimensional sense and activity of the main diamond, satisfying consumers' pursuit of novelty and uniqueness and eye-catching ability.

The utility model discloses an overline spliced bridge based on a prefabricated UHPC-T beam structure. The overline spliced bridge comprises T beams, steel cross beam components, shear key components and transverse prestressed tendons. The bottom of the T-beam is arranged on an abutment through a bridge support and comprises a web plate and a wing plate; the steel cross beam component is used for connecting and fixing the adjacent T beams, so that the adjacent T beams are connected into a whole to improve the structural strength and stability, the steel cross beam component comprises a pre-buried connecting seat pre-buried in a web and a steel cross beam, and the two ends of the steel cross beam are fixed to the pre-buried connecting seat of the adjacent T beams through high-strength bolts; the shear key component comprises key teeth and key grooves which are arranged on the two sides of the wing plate, and the key teeth of the adjacent T beams are embedded in the key grooves. The transverse prestressed tendons penetrate out of the wing plates to be tensioned, and the multiple T-beams are connected into a whole. According to the overline spliced bridge, the modularized UHPC-T beams are adopted, the structural height is reduced by means of the ultrahigh mechanical property of UHPC, and the overline spliced bridge adapts to the condition that the clearance under the bridge is limited; the shear keys are matched with the steel cross beams to replace a traditional cast-in-place wet joint and cross beam technology, old bridges do not need to be dismantled, the longitudinal section of a road does not need to be lifted, and the construction period is remarkably shortened.
