Embodiment Construction

[0028] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] see Figure 1-Figure 2 , in the self-flowing irrigation system for collecting rainwater on slopes according to the present invention, the water-conducting film 1 adopts a common shed film in the market, and the thickness is more than 1mm. Laying on the bottom and both sides, its function is not only to prevent rainwater leakage in the rain collecting ditch, but also to guide rainwater to the water storage film bag 4; the laying of the water guide film 1 must follow certain construction specifications to avoid pierced by sharp gravel;

[0030] The rain collecting culvert 2 is usually arranged along the slow slope of the contour line, and the water filter pipe 3 is placed in the ditch, and the bottom is laid with a water-conducting film 1 according to the shape of the ditch, and the two sides extend a ...

Abstract

The invention discloses a sloping field rainwater collection and in-place gravity irrigation system and a construction method thereof. The sloping field rainwater collection and in-place gravity irrigation system comprises a water guiding membrane, a rain collection underdrain, a water filter pipe, a water storage membrane bag and a water-saving irrigation pipe, wherein the water guiding membrane is paved at the bottom part and the two sides of the rain collection underdrain, the rain collection underdrain is allocated on a gentle slope along a contour line, the water filter pipe is arranged in the rain collection underdrain and is connected with the water storage membrane bag, a device for releasing medicament is attached to the water storage membrane bag, a water outlet is formed in the bottom part of the water storage membrane bag, and a ventilation hole is formed in the top part of the water storage membrane bag. According to the sloping field rainwater collection and in-place gravity irrigation system disclosed by the invention, natural rainfalls which are not uniformly distributed in both space and time can be accumulated and can be converted into a water resource which can be freely controlled and efficiently utilized, the gentle slope is changed into an irrigation land, and favorable conditions are provided for irrigation on dry farming in the gentle slope and organic mountain vegetable planting.

Description

technical field [0001] The invention belongs to the technical field of sloping land irrigation, and relates to an on-site artesian irrigation system for collecting rainwater on a sloping land and a construction method thereof. Background technique [0002] The traditional method of sloping irrigation is to use intercepting ditches and water cellars to collect and store rainwater, or in the south to use mountain ponds to store water, and then use pumps to pump water for irrigation. Water cellars have the advantage of cheap materials, but they also have the following disadvantages: [0003] (1) The interception ditch is an open ditch, which occupies a lot of land, has great damage to the vegetation on the slope, and has a great impact on roads and other facilities. Moreover, the sediment brought by the flood into the ditch is easy to silt the ditch and the water cellar. If a grit chamber is set up, in addition to designing and arranging this fixed facility, it must also be cl...
