Abstract
The utility model provides corrosion and wearing resisting metal bellows and belongs to the technical field of bellows. According to the utility model, the metal bellows are protected from damage caused by corrosion and wearing, and time for use of the metal bellows is extended. The technical scheme of the metal bellows is that linings are attached to inner walls of the metal bellows; the linings are made of polymer cement mortar, polyvinyl chloride, polyethylene or rubber plates; the linings are closely connected with the inner walls of the metal bellows in a sprayed, pressed attachment or extrusion molding manner; and inner surfaces of the linings are flat and smooth. According to the utility model, the linings can prevent corrosive sewage to corrode the bellows, and the linings has certain hardness and smooth surfaces, so wearing by sand and stone can be greatly reduced, and draining quantity and speed are effectively increased. The bellows are simple in structure and good in corrosion and wearing resisting effects; designed lifetime requirements of a culvert are satisfied; workload of post-maintenance is reduced; cost is reduced; and the bellows are novel pipelines which can be widely applied in highway and municipal engineering.
Description
Technical field
The utility model relate to a kind of in the engineerings such as highway, municipal administration, railway the metal bellows for pipeline, culvert, belong to Bellows Technology field.
Background technique
Progress along with technology, metal bellows is applied in large quantities in the engineerings such as highway, municipal administration, railway, metal bellows is mainly used in the construction of pipeline and culvert, finds the well damage of the metal bellows in some pipelines, culvert through using, working life is short, directly affect the service life of pipeline and culvert, had to change in advance, not only increased engineering work load and maintenance frequency, also affect road traffic, increased expense.Trace it to its cause, first, some metal bellowss of applying in highway, municipal engineering are being undertaken the function draining the sewage away, and some severe corrosive sewage are serious to metal bellows corrosion failure, shortened the working life of pipeline; Secondly, in highway engineering, use in metal bellows, particularly the longitudinal gradient of the culvert of mountain highway is large, flow rate of water flow is high, in current, be mingled with sandstone, the pipeline ancient piece of jade, round, flat and with a hole in its centre wearing and tearing of the metal bellows in culvert are corroded seriously, directly affected the working life of pipeline and culvert.In addition, in use also find, the ripple of metal bellows directly affects the roughness of pipeline, affects water displacement, is also need to be improved.
Model utility content
The technical problem that the utility model solves is to provide a kind of corrosion-resistant and nonabradable metal bellows, when this metal bellows some particular surroundingss in highway, municipal engineering are used, the wearing and tearing that can resist the corrosion of corrosivity sewage and alleviate debris flow, reach the requirement in working life in design.
The technological scheme solving the problems of the technologies described above is:
A kind of corrosion-resistant and nonabradable metal bellows, its wavy metal inner tube wall is attached with liner, liner is polymer cement mortar, or PVC＝polyvinyl chloride, or polyethylene, or rubber plate material, liner is by spraying, or press attachedly, and or extrusion molding mode is closely connected with wavy metal inner tube wall, the internal surface of liner is smooth smooth.
Above-mentioned corrosion-resistant and nonabradable metal bellows, described liner is attached to internal surface that the thickness on wavy metal inner tube wall is liner apart from the inner side crest 1-50mm of metal bellows ripple, and the length of liner is identical with the duct length of metal bellows.
Above-mentioned corrosion-resistant and nonabradable metal bellows, described metal bellows across footpath scope, be 300-10000mm, the pitch of waves 68-500mm, wave height 13-600mm.
The beneficial effects of the utility model are:
The utility model adopts metal bellows and lining coating composite structure, the liner material of metal bellows can prevent the corrosion of corrosivity sewage, inner lining material has certain hardness and smooth surface, can greatly reduce the wearing and tearing of sandstone, has also effectively improved water displacement and drainage rate.The utility model is simple in structure, corrosion protection and anti-wear respond well, has met requirement projected life of culvert, has reduced the workload of later maintenance, has reduced cost, is can widely used novel pipeline in highway and municipal engineering.
