Portion is the pipeline of hollow structure.Bellows can be divided into two kinds of metal bellows, nonmetallic bellows by constituent material；Can by structure
It is divided into hollow single wall layer and multilayer wall.
The inventors discovered that the existing buried large-bore corrugated conduit used in municipal rain dirt Drainage Projects is suitable due to it
Higher ring stiffness is required with special use environment, tensile property is strong and possesses the function of anti-sinking, due to plastics
Rigidity limits, and can only generally manufacture DN1000mm with the overall plastic bellows of lower relative aperture, objective reality 1. more than DN1000mm bores
Pipe line made up of full plastics, ring stiffness is low, does not reach the defects of buried pipeline construction requirement ring stiffness SN8 or more than SN8.2. overall plastic material
The pipeline of material high temperature and be exposed to the sun it is lower easily soften, the ripple of hollow structure deformed, collapsed the defects of recessed.3. backfill is constructed
Overall plastic wave crest easily can cause cave-in accident by hard thing pressure wound.
Then, inventor in view of this, adhere to that the relevant industries for many years enrich design and develop and the experience of actual fabrication,
Improvement is studied for existing structure and missing, there is provided a kind of novel alloy Type B winds corrugated pipe, to reach more
There is the purpose of more practical value.
Utility model content
The purpose of this utility model is to provide a kind of novel alloy Type B to wind corrugated pipe, to solve above-mentioned background skill
The existing buried large-bore corrugated conduit used in municipal rain dirt Drainage Projects proposed in art is since it is applicable in special make
There is higher ring stiffness with environmental requirement, tensile property is strong and possesses the function of anti-sinking, since plastics rigidity limits, one
As can only manufacture DN1000mm with the overall plastic bellows of lower relative aperture, the pipe line made up of full plastics of objective reality 1. more than DN1000mm bores,
Ring stiffness is low, does not reach the defects of buried pipeline construction requirement ring stiffness SN8 or more than SN8.2. the pipeline of ail-plastic materials exists
High temperature and lower easily softening of being exposed to the sun, make the ripple of hollow structure deform, collapse the defects of recessed.3. backfill overall plastic wave crest appearance when constructing
The problem of cave-in accident easily can be caused by hard thing pressure wound.
The utility model novel alloy Type B winds the purpose and effect of corrugated pipe, is reached by technological means in detail below
