[0054] In this example, during the normal maintenance process, the inside of the PVC pipe is saturated sand, the width of the road bed is W, and the length of the roadbed at the back of the platform is L u , when the gutter is filled with water, the capacity V is
[0055] V=2WL u h u (1)
[0056] There are about n horizontal outlets of PVC pipes on both sides of the roadbed, and the cross-sectional area of the outlets is
[0057] S=nπD 2 / 4 (2)
[0058] Gradually replenish the water stored in the slope protection vegetation soil through the saturated medium-coarse sand in the PVC pipe, and it takes about
[0059] t=V / kS (3)
[0060] In this embodiment, the vertical and horizontal beams are arranged staggeredly in each layer, and there is a filling area in the middle. Each layer of light soil subgrade is simplified as a composite foundation, the vertical and horizontal beams are regarded as "cross piles", and the filled light soil is regarded as soil. Each layer The b...
