By means of the design, the reinforcing device fills the gap in reinforcing measures of a national large diameter thin wall steel cylinder and lays an important foundation for popularization of an inserting steel cylinder structure. The reinforcing device is reasonable in design, easy to install, simple in reinforcing measures and excellent in stability, effectively enhances rigidity of the cylinder body, and can evenly transmit exciting force for vibrating and sinking the cylinder body, thereby reducing integrity transformation during sinking process, exerting a minimum effect on sinking resistance simultaneously and guaranteeing smooth vibration and sinking of the cylinder body, and the market prospect of the reinforcing device is promising.
Description
Technical field
The utility model relates to building, construction structure, specifically is meant the ruggedized equipment that offshore engineering structures such as being used for mole, shore protection, man-made island, harbour is built.
Background technology
Plug-in type large diameter thin wall steel cylindrical structure can be used for the construction of mole, shore protection, man-made island, harbour as novel offshore engineering structure, has stronger vitality.Along with continuing to increase of steel drum diameter and buried depth degree, the needed power of shaking of hitting of steel cylinder sinking is also increasing, rely on barrel itself that buckling instability and excessive deformation then take place easily, thereby cause the steel cylinder to sink difficult even failure, it is to finish the heavy important prerequisite of shaking smoothly that large diameter thin wall steel cylinder is taked effective reinforcement measure.
Large diameter thin wall steel cylindrical structure is used comparatively extensive in Japan, (diameter is greater than 20m, the high 30～50m of tube, the application precedent of wall thickness 14～16mm) but still do not have major diameter, big buried depth at home.And the general diameter of domestic existing steel cylinder is smaller, buried depth is more shallow, takes easy reinforcement measure or does not take reinforcement measure just can meet the demands, and the requirement of strength when the steel cylinder is sunk is still not outstanding.
According to the loading characteristic of Steel Thin-Wall cylinder major diameter, big buried depth, existing just making great efforts to seek to construct feasible, guarantees degree height and economic and practical large diameter thin wall steel cylinder reinforcement measure scheme.
Summary of the invention
At the existing deficiency of background technology, the utility model proposes the ruggedized equipment of the simple science of a kind of structure design, the high large diameter thin wall steel cylindrical structure of stability.
For achieving the above object, the utility model is achieved by the following technical programs: a kind of ruggedized equipment of large diameter thin wall steel cylindrical structure, comprise a cylindrical shell, the inside of cylindrical shell is provided with ribs and some hoop stiffening rings, cylindrical shell is provided with top stiffener and bottom stiffener at top and bottom correspondence, the outside weldings of cylindrical shell has wide tongue-and-groove, is welded with on the wide tongue-and-groove to strengthen embracing hand, and the cylindrical shell inboard of wide tongue-and-groove correspondence is welded with the local steel plate of strengthening.
Ribs comprises that some are strengthened perpendicular rib and some reinforcement cross ribs, strengthen perpendicular gilled rings on the inwall that is welded in cylindrical shell, the angle that the hoop of the perpendicular rib of per two adjacent reinforcements is certain at interval, strengthen cross rib is welded on cylindrical shell with certain perpendicular spacing barrel top, the hoop stiffening ring is set in the inside of cylindrical shell and is weldingly fixed on the bottom of cylindrical shell, wide tongue-and-groove is periphery in the outside of cylindrical shell, the wide tongue-and-groove of butt joint side offers docking port, the bottom of wide tongue-and-groove is provided with the steel plate that a shutoff is used, strengthen embracing the periphery that hand is welded on wide tongue-and-groove, the local steel plate of strengthening is held between top stiffener and the bottom stiffener, and local reinforcement steel plate is identical with the height of wide tongue-and-groove.
Further step is: the thickness of top stiffener is no less than 15mm, highly is no less than 1m, and the thickness of bottom stiffener is no less than 15mm, highly is no less than 0.5m.
Compared with prior art, the utlity model has following substantive distinguishing features and progress: large diameter thin wall steel cylinder is effectively reinforced, reasonable in design, installation is easy, reinforcement measure is simple, steadiness is good, effectively raise the rigidity of cylindrical shell, can transmit the exciting force of the heavy cylindrical shell that shakes uniformly, reduce the bulk deformation during sinking, minimum to the penetration resistance influence simultaneously, guarantee that shaking smoothly of cylindrical shell is heavy, the blank of the reinforcement measure of domestic large diameter thin wall steel cylinder has been filled up in this measure, for important foundation has been established in the popularization of plug-in type steel cylindrical structure.
