The specific embodiment
As shown in Figures 1 to 4, a kind of water and soil separates the dam, mainly is comprised of dam body 3, the Nei Ba slope body 8 that is positioned at the Wai Ba slope body 2 in the dam body outside and is positioned at the dam body inboard.The reservoir area inner bottom part that surrounds in Nei Ba slope body and peripheral landform 1 is provided with the water and soil isolating construction; Or be provided with the water and soil isolating construction at reservoir area inner bottom part and the Nei Ba slope body that Nei Ba slope body and peripheral landform surround.
Described water and soil isolating construction comprises:
Infiltration sand bed 5,9, for water and the silt of isolated by filtration water, infiltration sand bed 9 is positioned at the reservoir area inner bottom part, or is positioned on reservoir area inner bottom part and the Nei Ba slope body.The infiltration sand bed is positioned at every soakaway trench periphery, and when soakaway trench was substituted by infiltration channel, the infiltration sand bed was positioned at every infiltration channel periphery.The periphery of described every soakaway trench is equipped with the infiltration sand bed.The thickness of the infiltration sand bed of described soakaway trench periphery is for being at least 2cm, so that the silt in effective filtered water.Infiltration sand bed on the body of the described Nei Ba of being positioned at slope is provided with Sand-fixation net 13 outward, and Sand-fixation net can be cement web plate with holes, so that the sand bed that will seep water is installed on the body of Nei Ba slope.The infiltration sand bed is comprised of the sand of particle diameter 0.5～2mm, can be fine sand layer 0.5～1mm at the sand near the soakaway trench periphery, and all the other positions are rough sand layer 1.2～2mm, and the best gland blinding in infiltration sand bed upper end prevents the flood infiltration sand bed that destroys by rush of water.The infiltration sand bed preferably is arranged on the bottom surface, reservoir area or Nei Ba slope body of body front side, Nei Ba slope, and infiltration sand bed upper surface should be lower than the bottom surface, reservoir area or be lower than the external end face in Nei Ba slope.
The axial line of described every soakaway trench and gallery axial line angle are 30 °～90 °.
Domatic the be arrangeding in parallel of the external wall of soakaway trench and Nei Ba slope on the body of the described Nei Ba of being positioned at slope.The described soakaway trench 4 that is positioned on the body of Nei Ba slope is tilting.Described soakaway trench is the infiltration sand tube, or for the gather pipe of water seepage hole 14 of tube wall, such as cast iron pipe, pipe of cement or the plastic pipe etc. of the densely covered water seepage hole of tube wall.
Described soakaway trench is infiltration channel 16, and the infiltration channel upper end open is established infiltration orifice plate 15.Infiltration channel wall 17 is the cement web plate of the water seepage hole that gathers.Described several are 2～ten thousand, and namely several of soakaway trench refer to 2～ten thousand, set as required.
Gallery 11 is used for compiling the water that transmission is imported by each soakaway trench, and gallery is positioned at body bottom, Nei Ba slope, and gallery communicates with sluice way.
Sluice way 7, be used for control and discharge the interior water of gallery outside dam body, one end of sluice way communicates with gallery, and the other end of sluice way passes inside and outside dam slope body and dam body bottom, and to be positioned at the Wai Ba slope external, and sluice way is provided with the gate 6 that opens and closes this sluice way.Obviously, the sluice way lower storage basin that can communicate is with convenient water recycling of separating.Obviously, open the water of sluice way after with separation of sediment in the reservoir area flood period and discharge, the silt of reservoir area precipitation can form the farmland and cultivate.Can keep the suitable waterline in ground in the reservoir area if the water yield is discharged in control, be beneficial to farming with growing; Or formation eminence farmland, reservoir area, lower water storage coexistence effect.Then can form reservoir if close sluice way.
Meet Storm Flood Disasters, enter the flood 12 (or various water that contains a large amount of silts) that the reservoir area includes a large amount of silts, infiltrate rapidly in each soakaway trench at permeable layer place water, the infiltration in each soakaway trench compiles and flows into gallery again outside sluice way is discharged the storehouse, and infiltration stores recycling in lower storage basin.The silt of filter deposition forms the good farmland in the reservoir area.Control or close the gate of sluice way, the reservoir area capable of storing water, also capable of storing water is built up fields and is got both.
In a word, the utility model can carry out in the storehouse separating of water and silt fast with containing the large flood of quantity of sand and mud, the dual-use function of building up fields with water storage is arranged, the silt that makes in the dam deposition is plant development again, has small investment, and water and soil conservation is good, improve the ecological environment, prevent that drought and waterlogging from occuring, create a good condition to crop growth, reach the advantage of increasing both production and income.
