Wherein: 1-inverted T-shaped concrete pouring base, 2-slope protection body, 3-pond ridge concrete coping, 4-drain pipe, 5-sandstone inverted filter layer and 6-concrete prefabricated ecological brick.

Detailed Description

The present invention will now be described with reference to the accompanying drawings.

As shown in figure 1, the utility model provides a river crab culture zone ecological drainage ditch slope protection structure, including the escape canal that is located the slope bottom, the type of falling T concrete placement base 1 that the escape canal bilateral symmetry set up, the bank protection body 2, the ridge concrete of the pool bears down on one 3, drain pipe 4 and grit inverted filter 5.

The inverted T-shaped concrete pouring bases 1 located on the two sides of the drainage ditch are stable in shape, the drainage ditch is formed on the bases of the inverted T-shaped concrete pouring bases on the two sides, the collapse caused by the instability of the soil surface of the ditch can be prevented, the concrete pouring bases are suitable for being constructed in unstable water-bearing soil layers such as river crab culture areas, the bottoms of the concrete pouring bases are wide, the stability can be enhanced, and the collapse of the soil surface is prevented. The slope protecting body 2 is tamped by backfill soil, and the concrete prefabricated ecological bricks 6 laid on the slope protecting body can prevent weeds in the ditch from growing, spoil water quality after rotting and prevent sludge from being accumulated, thereby accelerating the water flow speed.
