Abstract
The utility model discloses a prestress steel cylinder concrete composite pipe which comprises a prestress steel cylinder concrete pipe body. The prestress steel cylinder concrete pipe body comprises a steel cylinder, a concrete inner layer, a concrete outer layer and a mortar protective layer and is characterized in that a polyvinyl chloride (PVC) panel layer or a poly ethylene (PE) panel layer is arranged on the surface of the inner wall of the concrete inner layer. Compared with the prior art, the prestress steel cylinder concrete composite pipe has the advantages that a PVC anti-corrosion panel or a PE anti-corrosion panel is lined on the inner wall of a conveying pipeline, so that various harmful substances are effectively isolated, service life of the conveying pipeline is prolonged, operating cost is reduced, and national economical benefits are improved. Besides, the inner surface of the PVC anti-corrosion panel or the PE anti-corrosion panel is quite smooth, after the panels are lined on the inner wall of the conveying pipeline, roughness coefficient of the surface of the pipeline is reduced below 0.10 from 0.014, so that flow speed of fluid is greatly increased, and specification on selecting of the pipeline is lowered.
Description
Technical field
The utility model relates to a kind of tubing, relates in particular to a kind of prestress steel cylinder concrete composite pipe.
Background technique
The built-in type conveyance conduit in people's lives, all is used widely in cities and towns, the rural construction; People live water, coal gas and the rock gas of usefulness, the basic employing all use the conveying of built-in type pipeline.In today of economic technology high speed development, some great Infrastructure, equipment are called lifeline engineering, and this type of construction project is related to the water safety in a city even an area, relation is produced, living guarantee, is related to the stable, harmonious of entire society.
For example: the conveyance conduit of different size, specification, Prestressed concrete cylinder pipe (PCCP) for example is at present in fields such as long-range water delivery, urban water guarantees, on a large scale, the use of long distance.The common distribution distance of conveyance conduit is long, and the region span is large.The life-span of tubing is extremely important, and life-span of not making any corrosion-resistant tubing is generally about 30 years, and is even shorter, and after this aseptic technic, the life-span of tubing promotes greatly, can reach 60-100.Because the installation of these pipe built-in formulas, in case the tubing corrosion, the people can't in time find substantially, until after finding serious the leakage, even have no progeny in carrying, just to pinpoint the problems, this often causes the adverse consequencess such as the people and national wealth suffer heavy losses.
At present, built-in type conveying pipeline inner wall corrosion technology is mainly contained the epoxide coal bituminous or epoxy resin paint of brushing, this material and concrete surface cohesiveencess are bad, will come off through behind the water soaking, and construction are complicated, and cost is high.
The model utility content
The utility model is in order to solve above-mentioned deficiency, a kind of prestress steel cylinder concrete composite pipe to be provided.
Above-mentioned purpose of the present utility model realizes by following technological scheme: a kind of prestress steel cylinder concrete composite pipe; comprise the Prestressed concrete cylinder pipe body; described body comprises steel cylinder, concrete internal layer, concrete skin and mortar cover, it is characterized in that: described concrete internal layer inner wall surface is provided with PVC sheet metal layer or PE sheet metal layer.
Described PVC or PE sheet metal layer are provided with T-shaped key or diamond pattern key, and described T-shaped key or diamond pattern key are implanted the concrete internal layer and fixed.
The utility model advantage compared with prior art is: be lining into a kind of PVC or PE corrosion protection sheet material at conveying pipeline inner wall, effectively isolate various harmful matters, improve the working life of conveyance conduit, cut operating costs, improved national economic profit.In addition, this PVC or PE corrosion protection sheet material internal surface are very smooth, be lining into this material after, the roughness value of pipe surface is reduced to below 0.010 by original 0.014, has greatly increased the flow velocity of fluid, can reduce specification on pipeline is selected.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view at A place among Fig. 1.
Fig. 3 is the structural representation of the T-shaped key of the utility model.
Fig. 4 is the structural representation of the utility model diamond pattern key.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1 and Figure 2; a kind of prestress steel cylinder concrete composite pipe; comprise Prestressed concrete cylinder pipe body 1; described body 1 comprises steel cylinder 2, concrete internal layer 3, concrete outer 4 and mortar cover 5, and it is characterized in that: described concrete internal layer 3 inner wall surface are provided with PVC sheet metal layer or PE sheet metal layer 6.
Such as Fig. 1 to Fig. 4, described PVC or PE sheet metal layer 6 are provided with T-shaped key or diamond pattern key 7, and described T-shaped key or diamond pattern key 7 are implanted the concrete internal layer and fixed.
The utility model is to be inserted in PVC or good PVC or the PE cylinder of PE corrosion protection board making in prestress steel cylinder concrete composite pipes internal mold outside in advance, T-shaped key or the diamond pattern key of this material back side stripe-shaped, then adopt the vertical vibrating moulding process that concrete is built, after concrete hardened fully, T-shaped or diamond pattern key was completely fixed together by the strip on PVC or the PE corrosion protection sheet material between PVC or PE corrosion protection sheet material and the concrete.
Structure of the present utility model can apply to the various tubing such as waste pipe, sewage pipe, pneumatic tube, transport pipe.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
