Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] The technical key of the present invention is to create an original combination of ordinary film and non-woven fabric or open foam layer 2 provided with a water-blocking film layer 5 on the surface as the main material of the drip irrigation pipe or drip irrigation belt. With the help of capillary action of non-woven fibers or open foam layer, the irrigation water seeps out from the drip irrigation pipe / passing water channel to the side seam. Discontinuous bonding points 4 are set on the water seepage side seam 3, and the gaps between the bonding points on the side seam form a water seepage channel. The amount of dripping water per unit length of drip irrigation or infiltration irrigation can be controlled by the spacing of the bonding points. If the spacing is large, the amount of dripping water per unit time and the same pres...

Abstract

The invention provides a double-film drip irrigation pipe / belt with water permeable side seams to solve the problem that the water outlets are blocked when the drip irrigation pipe / belts are buried. The drip irrigation pipe / belt has a simple structure and low manufacturing cost. The buried drip irrigation pipe / belt is characterized in that a buried drip irrigation pipe / belt main body is formed by oppositely bonding a water-blocking film and a non-woven fiber layer or opening foam layer provided with a water-blocking film on the single surface; the drip irrigation pipe / belt main body is provided with a water flow channel and two water permeable side seams; discontinuous bonding points are arranged on the water permeable side seams; and gaps between the bonding points on the side seams form a water permeable channel. The drip irrigation pipe / belt has the following beneficial effects that: the drip amount per unit length of the drip irrigation pipe / belt can be controlled via the space between the bonding points; the space between the bonding points, the shapes of the bonding points and the diameter of the water flow channel can be changed at any time according to the use requirement; and the production equipment is simpler than that of the existing drip irrigation pipe / belts, the investment is small and the production cost can be substantially reduced.

Description

technical field [0001] The invention relates to a double-membrane drip irrigation pipe or a drip irrigation belt, in particular to a side seam seepage drip irrigation pipe / belt suitable for field crops, and belongs to the technical field of water-saving irrigation equipment. Background technique [0002] Various drip irrigation pipes and drip irrigation belts currently used in the field of agricultural micro-irrigation technology are equipped with a set of labyrinths at the front of each drip outlet to damp and reduce the internal pressure of the drip irrigation pipe / belt, and to balance the output of each drip outlet. Pressure and water output, so as to ensure that the water output of each drip outlet is basically the same within a certain laying length of the drip irrigation pipe / belt. The labyrinth is roughly divided into two categories, one is formed separately, and then embedded in the drip irrigation pipe / belt, or inserted outside the drip irrigation pipe / belt, and the...
