Abstract
The utility model provides a compound pipeline which is used for the mortar transport and the concrete transport of the building engineering. The pipeline wall of the compound pipeline is layer compounding structure; an inner lining layer, a transition layer, a strength layer and a surface layer are positioned in turn from inside to outside; connecting elements are installed at both ends of the compound pipeline; the connecting elements at both ends of the compound pipeline can be hoop-clamping steel sleeves or metal loose flanges, and the metal loose flanges are provided with female surfaces. The inner lining layer is a thermoplastic plastic tube, the transition layer has the structure of continuous curved surface shape, the strength layer has the reinforced thermoset synthetic resin structure of mixed glass fiber and steel wires, and the surface layer has the reinforced thermoset synthetic resin structure of mixed glass fiber and synthetic fiber. The compound pipeline can effectively solve the disadvantages of the present mortar and concrete transport pipeline that the corrosive wear is easy to happen, the scale formation and the deposit of transport materials are generated at the tube wall, etc. The compound pipeline can be used for transporting the solid granules, the powder and the double-way fluid of solid and liquid.
Description
The utility model relates to a kind of building engineering with mortar, transmission and concrete transmission compound pipeline complex pipeline, also can be used as solid granulates, powder and solid, liquid two phase fluid conveying pipeline simultaneously.
Along with the rapid increase with skyscraper of developing rapidly of vehicle for construction, the development of pumping mortar concrete is very fast, but its delivery duct is still used carbon steel pipe.Because burn into worn-down synergy, thickness of steel pipe year, waste reached more than 1 millimeter, also with pitting, crevice corrosion etc., particularly serious is that transported substance had both strengthened the Flow of Goods and Materials resistance in tube wall incrustation, deposition in the pipe, has dwindled the payload space of pipe orifice again, cause operation pressure to increase, transport efficiency descends, even can cause " manage quick-fried " therefrom, personnel's life security is constituted direct prestige assist.Therefore, the safety hazard carried of steel pipe and economic irrationality are affecting always that the pumping mortar is concrete to be applied.
The purpose of this utility model is at the weak point in the above-mentioned background technology, provide a kind of in light weight, intensity is high, withstanding corrosion, wear-resistant, non-scaling, NEW TYPE OF COMPOSITE pipeline that transport efficiency is high.
The purpose of this utility model is achieved in that the tube wall of this compound pipeline complex pipeline for layer composite structure, is followed successively by inside liner, cambic horizon, intensity layer and uppermost layer from inside to outside; Pipe ends is equipped with attaching parts.
The attaching parts at compound pipeline complex pipeline two ends can be clip steel bushing or metal lap joint flange.
The inside liner of compound pipeline complex pipeline is a thermoplastic pipes, as polyethylene, polypropylene, haloflex, polyvinylchloride, polyamide, ABS etc., with give full play to its withstanding corrosion, wear-resistant, coefficient of friction is low, is difficult for the performance with cement, the fouling of mortar bonding.
Its intensity layer is to mix thermoset synthetic resins such as strengthening unsaturated polyester resin, epoxy resin, phenol resin, polyurethane between glass fibre and steel wire floor, with the intensity of abundant assurance compound pipeline complex pipeline, and effectively controls the radial deformation rate of compound pipeline complex pipeline.
The cambic horizon of the two is that the synthetic resin that spray in the plug helix that turning or grinding plastic pipe outer wall are processed, brush contain molding powder is made, both can guarantee the two bond strength height, make the embedding that intermeshes continuously of plastic inner lining layer and intensity layer again, form continuous curve surface shape structure, thereby can effectively overcome the two because of the friction stress that modulus of elasticity, linear expansion factor differences produce in the adhesive surface place, guarantee that the two is not stratified under impact, vibration, temperature alternating condition, do not ftracture.
Its superficial layer is to mix common enhancing by the high syntheticfibres of breaking elongation and fabric thereof and glass fibre to be added with ageing-resistant resin and to make, and can effectively improve the shock resistance and the tenure of use of multiple unit tube.
Because compound pipeline complex pipeline of the present utility model has adopted a layer composite structure, various materials are maximized favourable factors and minimized unfavourable ones mutually, thus have in light weight, intensity is high, withstanding corrosion, wear-resistant, non-scaling, advantage that transport efficiency is high.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is the structural representation in clip steel jacket composite pipe road
Fig. 2 is the structural representation of lap joint flange compound pipeline complex pipeline
The tube wall of compound pipeline complex pipeline is followed successively by inside liner 1, cambic horizon 2, intensity layer 3 and uppermost layer 4 from inside to outside.Pipe end is clip steel bushing 5 or metal lap joint flange 6.
Adopt the clip steel bushing to connect when wherein nominal pressure is less than 12MPa, nominal pressure adopts the metal lap joint flange of band female surface to connect during more than or equal to 12MPa.
Below in conjunction with embodiment, its processing technology is done further narration:
Nominal pressure adopts the clip steel bushing to connect during less than 12MPa.Its process operation step is: (1) by material category, nominal diameter, the wall thickness of the selected plastic inner lining pipe of operation technique requirement, and then with its surperficial hacking, and turning or grinding go out the plug helix of certain depth, width; (2) use the resin identical with the intensity layer, the molding powder identical with internal lining pipe adds an amount of curing agent, accelerator, diluent again, is made into the cambic horizon glue, and it is sprayed equably or brushes plastic pipe in appearance, makes cambic horizon; (3) treat the preliminary gel of cambic horizon after, adopt winding process that the tow that continuous glass fibre, steel wire rationally mixed is wound to the plastic pipe surface behind the resin storage tank impregnation, both filled full plug helix, reach certain winding thickness by designing requirement again; (4) accurately locate through rust cleaning, the clip steel bushing of handling that degreases off-the-shelf, directly be bonded in the pipe two ends; (5) continue with glass fibre and add ageing-resistant synthetic resin to twine the intensity layer to design wall thickness; (6) with mixing between syntheticfibres surface felt band (bar) and fiberglass surfacing mat belt, the common enhancing added ageing-resistant synthetic resin, twines outer surface layer, and this layer also can adopt hand to stick with paste and be this utility model product after technology is waited to solidify finishing.
Nominal pressure is during more than or equal to 18MPa, adopt the metal lap joint flange of band female surface to connect, press embodiment 1 control step, treat that (1), (2), (3) operation are finished after, adopt cold-press process to be inserted in lap joint flange 6, and be molded into the galss fiber reinforced resin joint of band awl at the multiple unit tube two ends; After treating its cure and demold, twine its intensity layer 2 by (5), (6) operation of embodiment 1, machined surface layer 4 is treated to be this utility model product after it solidifies finishing.
