the pipe body is a cuboid with 2 symmetrical openings on the side faces, a through gap is formed in the center of the top of the pipe body, and water drainage holes are formed in the side walls and the bottom of the pipe body;

the apron is "L" type, 2 the apron symmetry is arranged in the body top, 2 the apron top interval respectively with the gap that permeates water, the gap at body top aligns.

The gaps of the impervious stone surface layer hardly cause influence on the sense of pedestrians. When the rainwater falls, the excessive rainwater flows into the pipe body along the stone gap and the symmetrical cover plate crack, and the rainwater permeates into the ground along the drainage hole in the pipe body through the stone base layer.

The scheme is implemented in a non-saline-alkali land area, and the stone base layer sequentially comprises a rammed plain soil layer, a coarse gravel cushion layer, a graded gravel filter layer and a pervious concrete bonding layer from bottom to top; the drainage structure is a first drainage pipe arranged on the graded broken stone filter layer, so that excessive rainwater can be smoothly drained into the municipal rainwater pipe network through the first drainage pipe while rainwater is ensured to rapidly infiltrate during rainfall.

The scheme is implemented in a saline-alkali land area, and in consideration of the fact that saltpetering alkali caused by a high underground water level endangers the stone base layer, the drainage structure is arranged in blind ditches right below the horizontal arrangement position of the coarse gravel cushion layer and in grooves arranged in the rammed plain soil layer at intervals, and comprises coarse sand filled in the grooves and a second drainage pipe arranged in the coarse sand; the stone base layer also comprises a reverse osmosis filtering layer arranged at the top of the rammed plain soil layer. The reverse osmosis filter layer can prevent groundwater from being lifted due to the capillary action of water, and the drainage structures are positioned in the spacing grooves of the rammed vegetarian soil layer at lower positions to ensure that excessive rainwater can be quickly drained, so that the saline-alkali flooding caused by the invasion of water is prevented.

The utility model has the advantages and positive effects that: the hidden pipe is adopted for infiltration among the impervious stones, the completeness of a hard paving surface layer is guaranteed to the maximum extent, the infiltration efficiency is greatly enhanced, and meanwhile, a structural scheme for preventing salt and alkali return is provided in a saline-alkali area.
