Description
Technical field
The present invention relates to a kind of chemical compsn, particularly a kind of ground plastic draining pipeline PP Pipe Compound and method of manufacture thereof of burying.
Background technology
The municipal administration water supply and sewage work are one of city important leverages of being able to run well; The safety of sewerage system and weather resistance not only influence giving full play to of city function; And, urban environment intact to road and urban safety tide over and flood season etc. direct influence arranged all, is indispensable important component part in people's daily life.Along with development of city and progress of science and technology, the plastic underground drainage pipe is just in light weight with it, intensity is high, snappiness good, anticorrosion, wear-resisting, conveyance power of water big, the sealing joint performance is good, long service life, easy for installation and speed of application are fast etc., and characteristics are widely used in the storm sewer and sewer line engineering in city.
Stress cracking is a kind of manifestation that plastic conduit damages.Externally under the combined influence of the unrelieved stress, erection stress after load, the processing, underground and traffic load, plastic conduit cracks in the stress concentration position and expansion gradually, thereby finally causes tubing system to be destroyed; Or plastic conduit install with use in, by store, transportation is installed, treatment process is improper or environmental influence causes local scratch or crackle to expand (growth) in the long duration with relatively constant speed.
Particularly in bad engineering geology such as mud, mucky soil, dredger fill, collapsible soil, weak soil, swelled rock and soil, ever frost, salt marsh ground area; Erratic behavior rainfall, groundwater level fluctuation are big, the improper or concentrated excessive exploitation underground water of layout of waterhead area and induced environment geological problem area or because the area of the natural geology environmental variation that human large-scale engineering activity causes is prone to take place engineering geology environmental problems such as surface collapse, land subsidence, ground fissure easily.In above-mentioned area; Because the stress mobile or that distortion can make the part of tubing system bear on stratum is higher, the time is longer; Producing stress can maybe be because lax gradually or stress redistribution in thermoplastics pipeline system; Cause and form crackle then, or quicken the original crack rate of expansion.Therefore in bad engineering geology environment area, plastic draining pipeline raw material also should have superior environmental stress crack resistance outside possessing the snappiness that high Young's modulus becomes reconciled, to give is provided enough safe application performance and secular work-ing life.
