Abstract
A compound tube relates the improvement over compound tube structure. The utility model provides a compound tube which is high in strength, and excellent in endurance and impact resistance. The compound tube comprises a tube wall, and is characterized in that an ECC layer is arranged on the surface of the pipe wall.
Description
Technical field
The utility model relates to the improvement of combination pipe structure.
Background technique
ECC(Engineered Cementitious Composite), i.e. engineered cementitious based composites.
PP ECC is the PP project cement-base composite material, and seeing the patent No. for details is 201010010157.4, and name is called the Chinese invention patent of " a kind of high-toughness polypropylene fiber reinforced cement-based composite material and preparation method thereof ".
PVA ECC is polyvinyl alcohol engineered cementitious based composites.
Cement is widely used in the engineerings such as civil construction, water conservancy, national defence as a kind of important gelatinization material.Cement-based material has very high compressive strength, but exists tensile strength low, the poor and large shortcoming of fragility of resistance to cracking.Adding of fiber can improve its performance greatly in cement matrix, plays that resistance is split, greatly effect of enhancing, toughness reinforcing etc. three.ECC is to the improved product of fiber concrete, is the random distribution short fibre refinforced cement based composites through Micromechanical Design, and it is early stage that its research starts from the last century the nineties.PP ECC not only has advantages of superhigh tenacity, hypotonicity, durability, wear resistance and many seam crackings, and possesses the performances such as freeze thawing resistance, anti-carbonization, anti-erosion, shock resistance; In addition, it is cheap, is able to extensive use.
The application of the medium-and-large-sized pipeline of engineering construction is more and more many, such as natural gas transportation pipeline, large-scale water transmission pipeline, underground blow-off line etc., be embedded in underground or frame on the ground.Along with the development of construction industry, intensity and the durability aspect of large-scale pipeline proposed strict requirement, not firm, the Local Cracking of weld seam, local buckling and seriously corroded bring no small economic loss to pipeline rehabilitation simultaneously.
The deficiency that occurs in order to remedy above-mentioned large-scale pipeline need to increase constraint material in the pipeline outside.Described constraint material comprises steel structure or compound-material, but both costs are all very high, and a little less than the corrosion resistance of steel.
Summary of the invention
The utility model is exactly for the problems referred to above, provides that a kind of intensity is high, the combination pipe of good endurance, good impact resistance.
For achieving the above object, the utility model adopts following technological scheme, and the utility model comprises tube wall, and its structure outline tube wall surface is provided with the ECC layer.
As a kind of preferred version, be provided with epoxy resin layer between tube wall described in the utility model surface and the ECC layer.
As another kind of preferred version, ECC layer described in the utility model is PP ECC layer or PVA ECC layer.
Secondly, pipeline described in the utility model is steel pipe.
The utility model beneficial effect: the utility model utilizes the advantage of ECC to make pipeline possess the performances such as intensity is high, good endurance, good impact resistance.
In addition, show after deliberation, premium properties of the present utility model is irrelevant with size, and namely pipe diameter changeable (being roughly the scope of 76mm to 760mm) is applicable to various pipe-line constructions.
Secondly, the high anti-punching property of ECC has higher construction quality so that pipeline construction is faster.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further.The utility model protection domain not only is confined to the statement of following content.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B section enlarged view of Fig. 1.
Among the figure, 1 is that epoxy resin layer, 2 is that tube wall, 3 is that ECC layer, 4 is that flange plate, 5 is that bolt hole, 6 is weld seam.
Embodiment
As shown in the figure, the utility model comprises tube wall 2, and tube wall 2 surfaces are provided with ECC layer 3.The thickness of ECC layer 3 can be determined voluntarily according to actual requirement of engineering.
Be provided with epoxy resin layer 1 between described tube wall 2 surfaces and the ECC layer 3.By the glueability of epoxy resin, so that ECC and steel pipe have preliminary combination, constructability.Epoxy sealing is centered around on the tube wall 2.
Described ECC layer 3 is PP ECC layer or PVA ECC layer.PP ECC material is different from normal concrete, and cladding thickness is thin and without configuration reinforcement, the combination pipe good endurance, and PP ECC material itself is cheap in addition, so that overall expenses reduces economic benefits greatly.
Described pipeline is steel pipe.Give full play to steel and ECC advantage separately, and the performance after the combination so that no matter this combination pipe is at large-scale pipeline or in common pipe is built, all there is vast potential for future development much larger than performance sum separately; Can be used as the pipeline of carrying corrosive gas, liquid, powder of solid particles and discharging in the industries such as petrochemical industry, chemical fertilizer, agricultural chemicals, rubber, acid-alkali salt manufacturing industry and non-ferrous metal refinement, also can be used as sewage pipe on the ship, waste pipe, ballasting water pipe, ventilation duct etc.
Below in conjunction with description of drawings working process of the present utility model.
At first, pipe surface is cleaned out, and evenly smeared epoxy resin; The ECC material is wrapped in pipe surface (the ECC material leaves with a certain distance from the flange plate 4 of end, until rear cast) uniformly, forms the ECC covering.
Then, the combination pipe made flange plate 4 bolts by the end are closely connected, flange plate 4 borders are provided with the bolt hole 5 of some, and then flange plate 4 weld seams 6 with docking connect.
At last, at flange plate 4 docking sites ECC casting complete.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
