Problems solved by technology

[0002] As we all know, at present, the water pipes used for agricultural irrigation have different materials and inappropriate connection methods, but the common disadvantage is that in the process of farmland irrigation, a large amount of water resources are lost due to water seepage of the water pipes, and the water pipes are heavy and bear The pressure is small, and some water delivery pipes cannot be folded and rolled, so it is extremely inconvenient to carry, the labor intensity is high, the service life is short, and the cost is high. The edge of the mouth is lapped and synthesized, and water seeps out from the joint during irrigation, wasting water resources

Embodiment 1

[0014] like figure 1 Shown: The inner and outer layers of a single piece of PE woven fabric 1 are coated with a layer of colored A coating 2 and B coating 3 respectively, and then a waterproof layer is compounded on the outer layer of A coating 2 on the inner layer of PE woven fabric 1 Membrane 4, PE woven fabric 1 After connecting the two cut sides in the longitudinal direction, a soft belt is formed. The connection method of the two cut sides is to align the A ends 5 of the two cut sides, and coat a layer of A glue in the middle Layer 6, and then, fold the two cut edges that have been bonded together on the PE woven cloth 1 to the outside of the soft belt, and apply another layer on the contact between the two cut edges and the PE woven cloth 1 B viscose layer 7, water does not directly contact cutting edge so can not seep from this place.

[0015] Its advantages are: light weight, low labor intensity during transportation and handling, fast and convenient installation, str...

Embodiment 2

[0017] like figure 2 Shown: The inner and outer layers of a single piece of PE woven fabric 1 are coated with a layer of colored A coating 2 and B coating 3 respectively, and then a waterproof layer is compounded on the outer layer of A coating 2 on the inner layer of PE woven fabric 1 After the film 4 and PE woven fabric 1 are connected longitudinally with two cut sides, a soft belt is formed. The connection method of the two cut sides is to stagger the B ends 8 of the two cut sides back and forth. A layer of C viscose layer 9 is applied to the edge contact, and then the two staggered cutting edges are bonded together. One deck of D viscose adhesive layer 10 is coated on the contact position of a piece of cutting edge and PE woven cloth 1 in the front where the cutting edge is staggered, so it can not leak from this place because water does not directly contact the cutting edge.

[0018] Its advantage is identical with embodiment 1.

Abstract

The invention relates to a method for connecting a composite high-strength soft belt with a longitudinal interface thereof. The internal layer and the external layer of a single PE weaved cloth is coated by a colored A coating and a colored B coating respectively; furthermore, the internal layer of the PE weaved cloth is compounded by a waterproof film layer; the method for connecting two cut edges of the PE weaved cloth is characterized in that: the ends of the two cut edges are aligned or staggered from front to rear; the middle parts of the two cut edges are coated by a viscose layer respectively; the two cut edges of the PE weaved cloth are folded to the outside of the soft belt; subsequently, the contact part of the two cut edges and the PE weaved cloth is coated by the viscose layer;as the cut edges are folded edges, the water does not directly contact with the cut edges; therefore, the leakage does not occur. The method has the advantages of having light weight, convenient transportation and carriage, quick and convenient installation and strong anti-leakage, saving water resource, improving irrigation rate, reducing irrigation cost for each Mu of land, having low loss ratewhen repeatedly unfolding and folding and long service life for repeated use, reducing manufacturing cost and improving usage efficiency.

Description

technical field [0001] The invention relates to a connection method of a soft belt and its longitudinal interface, in particular to a composite high-strength soft belt and a connection method of a composite high-strength soft belt and its longitudinal interface, which are firm and impervious to water, high in strength and easy to process, with a composite waterproof membrane and the interface Background technique [0002] As we all know, at present, the water pipes used for agricultural irrigation have different materials and inappropriate connection methods, but the common disadvantage is that in the process of farmland irrigation, a large amount of water resources are lost due to water seepage of the water pipes, and the water pipes are heavy and bear The pressure is small, and some water pipes cannot be folded and rolled, so it is extremely inconvenient to carry, the labor intensity is high, the service life is short, and the cost is high. The edge of the mouth is lapped ...
