Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

As shown in fig. 1 ~ 4, the utility model discloses a hydraulic engineering side slope drainage structure, including the slope body 1, be located the concrete layer 2 on the inclined plane of the slope body 1, be located the catch basin 3 of slope body 1 upper end, be used for sheltering from apron 4 of catch basin 3, be located escape canal 5 on concrete layer 2, with catch basin 3 adjacent reservoir stratum 6, the waterproof layer 7 of 6 bottoms of parcel reservoir stratum and side and be located the planting layer 8 of 6 tops of reservoir stratum. The water storage layer 6 comprises a gravel layer 61 and a coarse sand layer 62, and the gravel layer 61 is positioned below the coarse sand layer 62; the planting layer 8 is a mud layer on which grass is planted. Because of the blocking of the coarse sand layer 62, the soil of the planting layer 8 is not easy to be mixed thoroughly downwards, thereby ensuring the water storage function of the water storage layer 6. The two side walls of the intercepting ditch 3 are respectively provided with a water seepage hole 31 and a water outlet 32, the water seepage hole 31 is lower than the water outlet 32, the water storage layer 6 is communicated with the intercepting ditch 3 through the water seepage hole 31, the water seepage hole 31 is over against the gravel layer 61, and the water seepage hole 31 does not exceed the boundary of the gravel layer 61. The drainage ditch 5 is communicated with the catch basin 3 through a water outlet 32.

The cover plate 4 is provided with the water inlet 41 with the aperture of 1-2 cm, so that water at the top of the side slope can conveniently flow into the intercepting ditch 3, and meanwhile, sundries are effectively prevented from entering the intercepting ditch 3, and the cleaning period of the intercepting ditch 3 can be correspondingly prolonged. The bottom of the intercepting ditch 3 is an inclined plane or a step plane, the height drop forms a sludge ditch which is close to the water outlet 32, impurities in water such as mud and broken stones are deposited in the sludge ditch due to the height drop, the water seepage holes 31 are not easy to be blocked, and the water storage function of the water storage layer 6 is ensured.

When the rainwater comes, the surface water filters debris through the grass on planting layer 8 after, gets into catch basin 3 through inlet opening 41, permeates into reservoir stratum 6 through infiltration hole 31 again, and waterproof layer 7 prevents that water from permeating down, and the 6 water level in reservoir stratum rises. After the water storage layer 6 is full of water, the water flows out of the drainage ditch 5 through the water outlet 32.
