Description
Technical field
The utility model relates to a kind of plastic tube technical field, specifically a kind of winding structure wall pipe of suitable polyethylenes under water.
Background technique
At present, existing high density polyethylene (HDPE) winding structure wall pipe is produced by standard GB/T/T 19472.2-2004 requirements, its Type B structured wall popes is generally take high density polyethylene (HDPE) as main raw material, being spirally wound on hollow tubular product on the polyethylene tube wall as auxiliary support structure, the structure-wall pipe material of making through hot winding shaping process.This tubing is widely used in the conveying engineerings such as the defeated draining in buried farmland, chemical industry draining, discharge of industrial wastes.In the prior art, because the Pipes Density of high density polyethylene (HDPE) preparation is much smaller than the density of water, for guaranteeing that product can be applied under water, generally will be at the fixing a plurality of concrete weight coatings of pipe outer surface, to avoid producing because tubing is lightweight the phenomenon of floating, but the problem that causes thus is, be balanced counterweight, the tube wall face must be smooth as far as possible, therefore, has to the thickness thickening of Flat belt, thereby cause cost of production to increase, and, during owing to construction the working procedure of concrete weight coating need to be arranged, so cause construction complexity, high in cost of production technical problem.
The model utility content
The purpose of this utility model just provides a kind of winding structure wall pipe of suitable polyethylenes under water, the problem that existing construction is complicated when using under water to solve existing polyethylene spirally enwound structure-wall tubular product, cost is high and difficulty of construction is large.
The purpose of this utility model is achieved in that a kind of winding structure wall pipe of suitable polyethylenes under water, is wound with the hollow ribbed pipe at polyethylene tube wall external spiral, is filled with concrete in the tube chamber of described hollow ribbed pipe.
Under technique scheme, the utility model can be realized like this:
The outer ribbed pipe that twines of described polyethylene tube wall is one deck, and described ribbed pipe and the welding of polyethylene tube wall are integrated.
The outer ribbed pipe that twines of described polyethylene tube wall is more than one deck, and every layer of described ribbed pipe is intervally arranged, and outer ribbed pipe and internal layer ribbed pipe are Chinese character pin-shaped tangent, and welding is fixed between the described tangent ribbed pipe.
The outer ribbed pipe that twines of described polyethylene tube wall is two-layer.
Suitable polyethylenes winding structure wall pipe production technology under water may further comprise the steps:
1. extruder is extruded 190 ℃ of polyethylene flat bands, is coated band, coats band coating PP skeleton pipe and forms the hollow ribbed pipe;
2. Flat belt twines at mould and forms pipe material inner wall;
3. producing the mobile trolley used winding control gear that suspends that is fixed with, described suspension is twined control gear and is comprised base, is fixed in the supporting frame on the described base and is installed on two position limit arms on the support frame as described above, and described position limit arm is at shaft rod upper sleeve sleeve pipe free to rotate to be housed; Ribbed pipe twines in the shape of a spiral at a certain distance after passing between two position limit arms on the described suspension winding control gear and is fused to the Flat belt outer surface, finishes the winding of ribbed pipe; In winding process, remove PP skeleton pipe starting point outer surface and coat band;
4. in the tubing PP skeleton pipe that winds, inject concrete;
5. after concrete setting, PP skeleton pipe starting point outer surface is applied high density polyethylene (HDPE).
The utility model adopts two position limit arms that twine in the control gear that suspend that the winding position of ribbed pipe is precisely controlled, thereby can guarantee that ribbed pipe can arbitrarily displacement in winding process.Because ribbed pipe can be realized the accurate control of winding position under the control of twining control gear that suspends, can accurately control the usage quantity of ribbed pipe simultaneously, and be filled in the intraluminal weight concrete of ribbed pipe.
The winding structure wall pipe of suitable polyethylenes under water that the utility model provides, in PP skeleton pipe, inject concrete and increase own wt, the On The Floating that produces because body is lightweight when avoiding using under water, save therefrom the process that concrete weight coating is set outside tube wall, both can reduce the use amount of Flat belt, thereby reduce production costs, because injecting the ring stiffness that concrete significantly improves tubing in the PP skeleton pipe, also make simultaneously construction simpler and more direct again; In addition, concrete is injected in the PP skeleton pipe, also can make this tubing weight even, moderate, when avoiding former external counterweight the uneven and body discontinuity equalization problem that causes of incident counterweight, body increases working life, seepage be difficult for to occur, safe and reliable, can be widely used in getting under water, in the drainage works field.
