Step 7 is covered with colour bar cloth in full slope surface A-B-C-D after the completion of excavating；After the completion of excavation, pressed at once from the faces DE of bottom
0.6m thickness placements in layers, which are built, fills out seepage of water A groups filler 1, and that fills fills out seepage of water A groups filler 1 and should reach speed per hour 160km/h railways
Roadbed bottom compacting criteria；
Step 2：While fill seepage of water A groups filler 1, while in the seepage of water A groups filler 1 layering be laid with TGXG 2, Tu Gongge
Grid 2 should be taken in 1.0m in side slope step 7；It fills out body simultaneously and fills out in seepage of water A groups filler 1 longitudinally every 3.6m, vertical direction in changing
It is embedded with water pouring floral tube 3 every 2.0m, the outlet of water pouring floral tube 3 should be on the main rib of skeleton bank protection 4；
Step 3：After the completion of whole seepage of water A groups fillers 1 fill, clears up, brushes flat slope surface EF and GH, then at the design position of slope surface
Set the groove for excavating skeleton bank protection 4, spats 8 and platform and intercepting ditch 5；Build by laying bricks or stones or pour spats 8, skeleton bank protection 4 and platform and
Intercepting ditch 5；
Step 4：It builds or pours lateral sulcus platform 9 by laying bricks or stones, it is made to be linked together with lateral sulcus 10 and spats 8；
Step 5：Base is dug by design size in lateral sulcus position, builds or pours lateral sulcus 10 by laying bricks or stones, make lateral sulcus 10 and lateral sulcus platform 9 and shield
Foot 8 is linked together；
Step 6：Base is dug by design size in gutter position, builds or pour gutter 11 by laying bricks or stones；
Step 7：In plant shrub greening protection in skeleton bank protection 4, shrub spacing 0.3m, after the completion of transplanting shrub, watering is supported
Shield.
Finally, temporary drainage facility is removed.
