Embodiment 1

[0015] Embodiment 1: see figure 1 and figure 2 The shown hill area slope storage and water retention device is mainly composed of structural components such as a surface filter 1, a funnel 2 and a cylindrical net bucket 3. The surface filter 1 can be a metal mesh structure or a plastic mesh structure, and is located on the ground surface above the funnel 2. Its filtering effect prevents debris such as sediment from entering the device and affecting the water seepage and storage function of the device.

[0016] figure 2 It can be seen that the lower surface of the surface filter screen 1 is closely attached to a funnel 2, which is used to collect as much water as possible through the filter screen and guide it into the underground cylindrical net bucket 3.

[0017] Cylindrical mesh bucket 3 has multiple structural modes, for example, it can be a cylindrical barrel rolled into metal mesh, and circular metal mesh is all housed on the left and right ends. Also set the net buc...

Embodiment 2

[0026] Embodiment 2: On the basis of Embodiment 2, a floating body 13 is set in the reservoir 12, and a positioning rod 14 is connected vertically upward in the center of the floating body 13, and a positioning ring is set on the positioning rod 14 in the middle of the funnel 2 15. The positioning ring 15 is sleeved on the inner wall of the funnel 2 through the inner bracket 16.

[0027] In this embodiment, the upper part of the funnel can be temporarily isolated by using the floating body 13 , and the water storage in the funnel can be regarded as water storage, which can temporarily block the water storage in the funnel 2 . Because the buoyancy of the floating body 13 is relatively large, it is necessary to wait for the water level in the reservoir 12 to drop to a certain extent before releasing the water stored in the funnel, thereby achieving the effect of delaying water storage.

Abstract

The invention discloses an impounding and water-retaining device for a slope surface in a hilly region, which comprises a water storage part and drainage part which are arranged underground, wherein the water storage part is a horizontally arranged cylindrical net barrel, two ends of the water storage part are sealed by end surface nets, the inner side of the cylindrical net barrel is filled withsan and gravel stone to form a sand and gravel water seepage layer, the upper part of the middle part of the cylindrical net barrel is connected with a hopper, the lower end of the hopper is communicated with the sand and gravel stone layer area, and the upper end of the hopper is flush with the ground surface and is sealed with a surface filter screen. The device is simple in structure and convenient to manufacture; the three-dimensional irrigation in the middle and deep layers is achieved, the surface evaporation is effectively reduced, and the effective utilization rate of water is improved; the device is not limited by water quality and has wide application range; combined with the function of impounding the and runoff, the soil and water loss is effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of water collection and irrigation equipment, in particular to a device for retaining and storing water on slopes in hilly areas. Background technique [0002] Due to the limitation of natural conditions and the result of human activities for a long time, the forest coverage rate in my country is very low, and soil erosion is serious. At present, the main way to solve soil erosion is afforestation. The biggest problem is that there is not much groundwater in this kind of place, so the health of trees is seriously affected, and the mortality rate is high; and due to the impact of terrain, the cost of laying irrigation equipment is relatively high, and the traditional ground irrigation method is to infiltrate the roots from the ground. The disadvantage of this method is that: on the one hand, the loss of irrigation water caused by evaporation is serious; on the other hand, due to the small amount of irrigation w...
