Embodiment 1
[0030] Such as figure 1 The construction structure diagram of the siphon drainage planting roof structure shown mainly includes concrete roof 1, waterproof membrane 2, siphon drainage tank 3, polymer protective drainage special-shaped sheet geotextile 4, leveling layer 5, backfill soil 7, and breathable observation tube 10 , Prefabricated concrete fixing block 11 , stereotyped sewage intercepting tank 14 , drainage ditch 20 . Lay a leveling layer 5 on the concrete roof 1, lay a waterproof membrane 2 on the upper part of the leveling layer, lay a polymer protective drainage special-shaped sheet geotextile 4 on the waterproof membrane, and lay a siphon drainage groove 3 on the upper part of the polymer protective drainage special-shaped geotextile. The drainage groove discharges water into the drainage ditch 20, the top of the drainage ditch is provided with a stereotyped sewage interceptor 14 to filter debris, the siphon drainage groove is provided with a ventilating observatio...
Embodiment 2
[0035] The main construction process of the siphon drainage planting roof structure construction is as follows:
[0036] Step 1, leveling layer construction: use concrete to level the upper part of the concrete roof 1;
[0037] Step 2, construction of waterproof membrane: install waterproof membrane 2 on the upper part of leveling layer 5;
[0038] Step 3. Laying of the geotextile geotextile for protection and drainage special-shaped geotextile: use the geotextile rapid laying device 30 to lay the geotextile 4 for the geotextile protection drainage special-shaped sheet, install the geotextile roll 33 in the middle of the geotextile rapid laying device, and then lift Pull the push-pull handle 32 to advance the geotextile quick-laying device, and at the same time, compact the laid geotextile through the compaction drum 34 to ensure the smoothness of the geotextile laying;
[0039] Step 4: Install the siphon drainage tank: connect the adjacent siphon drainage tank through the buck...
