The water diversion structure comprises a water diversion cylinder and water diversion strips, wherein the water diversion cylinder is of a cylindrical structure with two sealed ends, a water storage material is arranged in the water diversion cylinder, one open end of the water diversion cylinder is connected with a plurality of water diversion strips, the positions of the water diversion strips correspond to the positions of the water diversion notches one by one, the water diversion cylinder is attached to the inner wall of the pipe body, the water diversion strips are attached to the outer wall of the pipe body after being drawn out of the pipe body along the water diversion notches, and the water diversion cylinder and the water diversion strips are both prepared from materials with strong capillary action;
preferably, the water dividing cylinder and the water diversion belt are both prepared by processing cotton fibers;
when the grass planting lattice main bodies are laid, the two adjacent grass planting lattice main bodies are connected through the outer frame, and the connecting mode comprises clamping and bonding.
the installation and laying method of the grass planting grids comprises the following steps:
tamping the foundation to ensure that the compactness of the foundation soil reaches more than 85 percent;
paving a layer of mixed sand stone with the thickness of 10-20cm on the surface of the foundation layer, and flattening and rolling to obtain a sand stone cushion layer, wherein the mixed sand stone is obtained by uniformly mixing medium coarse sand, clay and crushed stone with the particle size of 5-20mm according to the weight ratio of 1:3: 6;
Sealing the opening end of each pipe body through a cover or a film, then laying water storage pipes distributed in a net shape on a gravel cushion layer, then laying a layer of substrate on the gravel cushion layer, then laying a layer of medium coarse sand on the surface of the substrate, flattening and rolling to obtain a substrate layer and a filter layer, embedding the water storage pipes in the substrate layer and the filter layer, removing the medium coarse sand higher than the water storage pipe part, and then removing a sealing element at the opening of the pipe body, wherein the substrate is obtained by uniformly mixing the medium coarse sand, cultivated soil and crushed stones with the particle size of 5-20mm according to the weight ratio of 1.5:6: 2.5;
through setting up the filter layer of constituteing by well coarse sand, when water takes earth and broken blade to below, play the filter effect, avoid a large amount of earth impurity to reach the opening one end place degree of depth of body, lead to a large amount of impurity to get into the body, cause the pollution of the interior pollution of body even water storage material.
