Problems solved by technology

[0002] With the rapid development of urbanization in our country, man-made mountain consolidation such as quarrying, excavating mountains to fill the sea, and splitting mountains to open roads have caused certain damage to the mountain body. When the formed mountain slope is undergoing ecological restoration in the later stage, the conventional irrigation mode needs to be determined. Regular management and maintenance by people, if not careful, it will be difficult to provide the water required for the good growth of slope plants, so it cannot be widely promoted
In addition, the slope water interception is currently treated as excretion, which is not combined with irrigation, which is a waste

Embodiment Construction

[0011] With reference to accompanying drawing, grit chamber 2 of the present invention is communicated with rainwater collecting pipeline 1, and its bottom has blowdown valve 3, has channel 4 at the side wall top of grit chamber by reservoir 7, and channel entrance is laid with filter screen 5, With activated carbon sheet 6, the water storage tank 7 is connected to the dripper setting 10 for irrigation by the black soft dry pipe 8 and the black soft branch pipe 9.

[0012] The sand settling tank 2 of the present invention has an open tank body, and the size of the tank body is determined according to the local average annual rainfall and the number of connected rainwater collection pipes.

[0013] The length and width dimensions of the channel 4 according to the present invention are set according to needs.

[0014] The filter screen 5 of the present invention is a stainless steel wire mesh suitable for filtering under acid and alkali environments, and must have the characteri...

Abstract

A system for collecting and purifying intercepted water on a side slope for irrigation relates to a system for irrigating a sloping field with rain water. A sand sediment trap is communicated with a rain water collection pipeline, and a blow off valve is arranged below the trap; a channel is arranged between the sand sediment trap and a water storage tank; a filter screen with active carbon pieces is laid at an inlet of the channel; the water storage tank is connected with a dropper device for irrigation by a pipeline. The rain water of the surface runoff caused by rainfall and the rain water in a ground rain water well flow into the rain water collection pipeline through a rain water collection pipeline network. The rain water is collected in the channel, filtered and purified by the filter screen and the active carbon pieces at the inlet of the channel, and then flows into the water storage tank; and continuous drop irrigation is realized by the dropper device. The blow off valve is opened to eliminate impurities when the impurities reach a certain amount. The system realizes effective combination of a rain water collection and treatment system and a side slope irrigation system, solves a difficult problem of hard utilization of the rain water, is suitable for the side slopes of different types, and minimizes unstable side slope factors such as slope wash and the like caused by direct rain water drainage on the side slope.

Description

technical field [0001] The invention relates to a system for irrigating slope fields by using rainwater. Background technique [0002] With the rapid development of urbanization in our country, man-made mountain consolidation such as quarrying, excavating mountains to fill the sea, and splitting mountains to open roads have caused certain damage to the mountain body. When the formed mountain slope is undergoing ecological restoration in the later stage, the conventional irrigation mode needs to be determined. People regularly manage and protect it. If you are not careful, it will be difficult to provide the water needed for the good growth of slope plants, so it cannot be popularized in large quantities. In addition, the slope water interception is currently treated as excretion, which is not combined with irrigation, which is a waste. Contents of the invention [0003] The purpose of the present invention is to aim at the above-mentioned present situation, aiming to prov...
