2 cm high top greening planting drain plate of Dali garage

  Plastic drainage board is made of polyethylene plastic base plate by stamping into conical protrusion (or hollow cylindrical porous)
The top coal of the conical protrusion is connected with a layer of filter geotextile to prevent the passage of soil particles, so as to avoid the blockage of the drainage channel and smooth the drainage of the channel
The traditional drainage method uses bricks and tiles as the filter guide layer and more pebbles or gravel as the filter layer to discharge the water
Product features:
The drainage board plays an important role in the construction period of civil engineering and the normal use and service life of structures
Coiled material drainage board and porous seepage pipe form an effective drainage system, and cylindrical multi empty drainage board and geotextile also form a drainage system, so as to form a system with water seepage, water storage and drainage functions

Application fields:
Garden Engineering: garage roof greening, roof garden, football field, golf course and bathing beach engineering
Municipal Engineering: road subgrade, subway tunnel
Construction works: upper or lower layer of building foundation, indoor and outdoor walls of basement, roof anti-seepage and thermal insulation layer, etc
Traffic engineering: highway, railway subgrade, embankment and slope protection layer
Laying procedures:
1
Clean up the paved garbage and level with cement so that there is no obvious concave convex
2-5 & permil is required for the roof of outdoor garage and roof garden; Slope making

2
Roof greening and outdoor garage roof greening can be equipped with porous seepage pipe, so that the water discharged from the drainage board can be centrally discharged to the nearby sewer or the nearby urban sewer

3
The basement ground is impermeable, and the floor is overhead on the foundation, that is, a layer of drainage plate is made before the floor is made, the circular protrusion is downward, and a blind ditch is left around, so that the groundwater can not come up
The seepage naturally flows into the surrounding blind ditch through the space of the drainage plate, and then into the sump through the blind ditch

4
The basement wall is impermeable
Drainage boards can be laid on the main wall of the building, and the round protrusion faces the main wall
A layer of single wall shall be built outside the drainage plate or steel mesh powder cement shall be used to protect the drainage plate, so that the space of the water seepage plate outside the wall is straight to the blind ditch and to the sump

5
When laying the drainage board in any section, attention shall be paid to: do not let the garbage such as soil, cement and yellow sand enter the front space of the drainage board, and the space of the coiled drainage board shall be unblocked

6
When the drainage board is laid, protective measures shall be taken as far as possible
When the drainage board is laid on the layer or outdoor garage, backfill shall be done as soon as possible to prevent the drainage board from being disordered by strong wind and affecting the laying quality
The basement and interior wall waterproof shall be protected as soon as possible to prevent the drainage board from being damaged by people or objects

7
The backfill is cohesive soil
It is ideal to lay 3-5cm yellow sand on the geotextile, which is conducive to the water filtration of the geotextile; If the backfill is a nutrient soil or light soil, there is no need to lay another layer of yellow sand
This soil itself is very loose and easy to filter water

8
During the laying of the drainage board, the lower 1-2 fulcrum can be overlapped with the right side of the side, and the two bottom plates can also be overlapped with geotextile
As long as no soil enters the drainage channel of the drainage board, the drainage can be kept smooth
