Abstract

A water storage facility for mountain area, hilly region, island or desert is a series of water-storing bags arranged in gullies,and is composed of water-clarifying pool, reservoir, a group of water bags in the reservoir, pipeline for communicating water-clarifying pool with the bags and water discharge pipes connected to bags. Its advantages are no leakage, no vapourization, and has other additional functions such as bringing small valley under control.

Description

A kind of water storing installation in hilly area

The present invention relates to the mountain region erosion and torrent control works, specifically a series of mountain region retaining utricules.

As the engineering of controlling soil erosion, multiple modes such as contour interception, gully head protection works, check dam are arranged in the mountain area.As contour interception is by the ground elevation classification intercepting drain to be set in the catchment, directly tackles the highland runoff, directly enters outer river then, when the top of region of no relief is the hillock, hills, build the left-falling stroke Great Gulch along toe, the interception runoff of sloping field, directly enter outer river, make it not import the lowland, Plain.Gully head protection works then is an erosion and torrent control works of building the ditch head, it has water storage type and sluicing formula gully head protection works, water storage type continous way retaining ditch and embankment and intermittent type retaining ditch and embankment arranged again, also has wall waterlogging pond, a kind of ridge, its practice is to repair a flood retention ditch ridge above the ditch head, cuts off the outlet of slope runoff hyposulculus, and builds the waterlogging pond in suitable place, water is introduced in the pond, be used for drought resisting or supply livestock consumption.Check dam then is the engineering of interception silt in the raceway groove of mountain area, it often builds many check dams successively in a raceway groove, form the check dam group, can be divided into native check dam, stone check dam, timber check dam, steel concrete check dam etc. according to the constructional materials difference, its effect is to retain silt, slows down the raceway groove water velocity, alleviates downstream mountain torrents harm and anti-upward bottom of trench incision and the expansion of ditch bank, and it is flat that raceway groove is become silted up piecemeal, becomes terrace, available dam.More than various engineering measures all played the flood control flood storage, the good result that conserves water and soil, its weak point are in the utilization of retaining, because seepage and evaporation, retaining can not more effectively be utilized when arid.

The water-storing device that the purpose of this invention is to provide a kind of mountain region Small Watershed Management, it can alleviate soil erosion in effective flood retention flood storage in flood season, can be to supply water effectively in the downstream in dry season again.

This water storing installation in hilly area is made up of clear water reservoir and reservoir, place one group of retaining utricule that communicates with one another in the reservoir, clear water reservoir is communicated with the retaining utricule by the water input pipe, on the retaining utricule and be provided with the water output duct, also is provided with the fixedly anti-band that pulls out of utricule on each retaining utricule.This water storing installation in hilly area is arranged in the raceway groove in mountain region, and each raceway groove can be provided with many groups as the case may be, to stop, to accumulate the flood in flood season.

Interim when flood season, the flood of letting out at first enters clear water reservoir down, and silt is avaled, water in clear water reservoir reach a certain height, then, constantly flow in the one group of retaining utricule that interconnects in the reservoir, a plurality of utricules in a group are full of water by the gravity flow or the siphonage of water input pipe.Because outermost utricule volume is big in one group of air bag, it highly is higher than the inside utricule after being full of water, and a water storage space had been formed again on its top after utricule held full water like this, therefore, after the water in the clear water reservoir is excessive, just this water storage space can be full of water.After this reservoir held full water, water flowed to next clear water reservoir and reservoir again, thereby reached the purpose of flood retention flood storage.This retaining mode can prevent the evaporation and the seepage of retaining effectively owing to adopted the retaining utricule.Can be effectively when dry season downstream farmland and water unit supply water.This kind water-storing device can be used for the Small Watershed Management in mountain area, hills, island, desert, outskirts of a town, prevents erosion, and the generation of landslide and mud-rock flow can be accumulated the water in dry season again effectively.

Accompanying drawing is the schematic diagram of this water storing installation in hilly area.

Below in conjunction with accompanying drawing the present invention is illustrated.In the accompanying drawing, 1 is clear water reservoir, and it is heavy clean to be used for flood, and following reservoir 7 is a rectangle, level at the bottom of the pond, if the dark 8m in pond, wide 2.5m, long 100m can retaining 20,000 m ³Chi Like places 8～10 retaining utricules 2, and a utricule volume of outermost maximum, and is highly the highest, and the retaining utricule is made by the plastic sheeting of band reinforcing rib, promptly adds the reinforcing rib that one deck macromolecular material is made in the middle of plastic sheeting.Have water input pipe 5 to be connected between the retaining utricule of clear water reservoir and reservoir, and each retaining utricule interconnects, pump valve control is arranged on the water input pipe.As shown in drawings, each is organized has water output duct 6 to connect between the retaining utricule, and by valve control, supplies water downstream when being used for dry season.Water input, output duct can be made by metal tube or plastic pipe.Each retaining utricule has been provided with anti-the pulling out of fixation and has been with 3, anti-pulling out with 3 by being fixed in the nylon tape on the utricule and being connected with the pile 4 that is fixed in ground by metal ring, so that utricule is fixed in the reservoir.
