Description
Technical field
The utility model belongs to municipal administration, industry, mining industry etc. and uses pipeline field, provides especially a kind of heavy caliber to, waste pipe.
Background technique
Along with the sustained and rapid development of China's economy, urban size expands rapidly, and supplying water appears in increasing city, draining difficulty.Build extensive water delivery engineering very urgent, adopting pipe laying waterline is necessary selection scheme.At present, alternative pipeline has steel pipe, concrete pipe, concrete reinforced pipe, prestressed concrete pipe.Wherein, the maximum nominal bore diameter that does not configure the concrete pipe of steel structure in tube wall only has 600mm, is only suitable for the little discharge capacity applications that supplies, and extensive water delivery engineering must be selected other several pipelines.The principal element of considering while selecting pipeline has: reliable degree, construction and two aspects of maintenance cost.
Steel pipe is large from heavy and light, rigidity, but cost high, be subject to environmental corrosion, later maintenance expense is high.For reducing engineering cost, builder is current is more to select steel and the compound pipeline of concrete.Except cost is low, bi-material has made up weakness each other mutually, performance strong point separately, thus make steel/concrete composite pipe there is very high bearing capacity, general all higher than the steel and the independent bearing capacity sum of concrete that form pipeline.In addition, there is passivation because the alkalescence of concrete self can make steel surface, greatly improved the corrosion resistance of steel in concrete.
But the steel structure concrete pipe of existing Production and application standard exists again deficiency at present, is restricting and is applying.Steel in steel structure concrete pipe mostly adopt high tensile steel at present, and object is to improve bearing capacity and reduce deadweight.As the Twisted Steel of regulation in " push pipe reinforced concrete pipe standards " should meet " JC/T540 ", specify that the minimum yield strength of Deformed Steel Bars used is 550MPa.And the yield strength of cold drawn wire in prestressed concrete pipe (PCCP) is generally more than 1550MPa, according to IISI's mechanical properties of materials---intensity is classified, this class steel structure belongs to high-strength steel (270---700MPa) and super-high strength steel (>700MPa).Practice shows, this class steel counter stress corrosion cracking sensitivity.Stress corrosion cracking is the cracking that material causes under stress and corrosive environment acting in conjunction, and this is stress and the symphyogenetic result of corrosion.If only have an aspect, stress or medium effect, cracking destruction can not occur, but in the time of the two synergy, but can ftracture very soon.Therefore, occur when stress corrosion cracking, stress may be very low, and the corrosivity of medium may be also very weak, and also, just due to so, stress corrosion cracking is often ignored, and causes contingency constantly to occur.Conventionally in specific industrial environment, there is stress corrosion cracking in Ordinary Steel, high-strength steel in physical environment, as there is stress corrosion cracking in rainwater, seawater.In addition, due to the development of the modern industry, material working environment is more and more harsher, and stress corrosion problem also becomes increasingly conspicuous.
The concrete pipe made from current standard, adopt high-strength steel structure is the in the situation that of its concrete degradation failure, and risk can constantly increase.And present stage to transporting on a large scale engineering, as the life requirement of waterline also improved a lot more in the past, be increased to 50-100 from 20-30, therefore, need the better tubing of development durability badly to meet the demands.
Model utility content
