Abstract
The utility model discloses a kind of foaming reinforced plastic entwining tube, form by by helically-wound shaped plastic tube, be provided with foaming layer between the outer wall and inwall of wrapped tube, be be respectively arranged with rib and retaining groove at the two ends of plastic winding section bar, the utility model has the advantages that anti-pressure ability is strong, lightweight, the resistance to tension of body axial direction is high.
Description
Technical field
The utility model belongs to plastic tube technical field, especially relates to a kind of foaming reinforced plastic entwining tube.
Background technique
Along with the development of Urbanization in China, municipal pipe network construction is constantly accelerated, and increases year by year the demand of various drainage pipe.Plastic drain-pipe have compared with the tubing such as traditional cast iron tube, reinforced concrete lightweight, corrosion-resistant, resistance to water-flow is little, energy saving, easy for installation, have the advantages such as good adaptive capacity to the distortion of ground, therefore plastic drain-pipe obtains in municipal pipe network construction field and develops rapidly.Current plastic drain-pipe mainly contains bellows, entwining tube two kinds, and corrugated pipe production equipment is expensive, can only produce diameter 1800mm by condition restriction is maximum at present.Compare bellows, entwining tube manufacturing mechanism is cheap, and entwining tube can accomplish diameter 3000mm at present; But entwining tube many employings hollow tubular band spiral winding forms, owing to being hollow structure, so pipe structure intensity is lower, for improving the structural strength of body, the at present mode adopting steel strip reinforced more, but this structure exists that complex process, cost of production are high, steel band corrosion, steel band with plastics in conjunction with illusive problem.
Summary of the invention
The purpose of this utility model is the deficiency of improvement prior art and provides the foaming reinforced plastic entwining tube that anti-pressure ability is strong, lightweight, the resistance to tension of body axial direction is high.
The purpose of this utility model is achieved in that a kind of foaming reinforced plastic entwining tube, forms, be characterized in being provided with foaming layer between the outer wall and inwall of wrapped tube by by helically-wound shaped plastic tube.
In order to realize the purpose of this utility model further, can be respectively arranged with rib and retaining groove at the two ends of plastic winding section bar.
In order to realize the purpose of this utility model further, can be provided with stiffening rib at the pipe outer wall of wrapped tube.
In order to realize the purpose of this utility model further, can be that the foaming layer between the pipe outer wall of wrapped tube and inwall is provided with partition.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model foaming is strengthened entwining tube and is made up by helically-wound shaped of plastic material, plastic material is made up of foaming layer between outside and inside tube wall external belt muscle, tube wall, the stiffening rib of tube wall can improve the anti-pressure ability of product, improve body rigidity, inner foaming layer is when proof strength, the weight of product can be reduced, be convenient to install and transport, reduce cost of production simultaneously.The two ends of plastic material are provided with rib and retaining groove, and when being wound around, adjacent plastic material rib and retaining groove fasten mutually, increase the resistance to tension of body at axial direction; Foaming layer is provided with partition, is suitable for the continuous seepage of super sized type pipeline.
