Liuzhou multi specification garage plastic water storage board

  Now there are more and more high-rise buildings in the city, and there are underground garages with high-rise buildings
So how to solve the drainage problem of Garages: pebbles were used as drainage layers in the past, which was heavy and difficult to transport, troublesome construction and long construction period
Now the drainage board is made of HDPE plastic, which can store water and drain water
The load is light, and can prevent plant root puncture
The construction is very simple and the construction period is greatly shortened
Compared with the previous pebble drainage, it reduces the pressure of water on the waterproof layer
Niuniu drainage board manufacturer produces drainage boards, which can be produced according to the requirements of customers
The models of drainage boards planted on the garage top include 0

The plastic drainage board is 15m long and 2m wide in the form of coiled material
The secondary drainage board can block the root thorn, drain smoothly and have high compressive strength
During construction, it is only necessary to lay the ground flat without large stones and gravel, and then lay the drainage board
It is only necessary to overlap the edges or weld them
Then lay a layer of geomembrane on the upper layer to prevent sand from blocking the drainage protrusion of the drainage board

Construction and laying method of planting drainage board on garage roof
1
After the construction of waterproof layer and its protective layer is completed, the drainage board shall be paved
The drainage gradient of the base course shall meet 2 & permil~ 5‰;
2
Pave the cup-shaped mouth of the drainage board upward and buckle the perforations;
3
The drainage board shall be covered with geotextile, and the geotextiles shall be overlapped for 10 ~ 20cm to prevent muddy water from passing through the geotextile and silting the water filtration system, resulting in poor drainage and reduced water filtration;
4
Lay 10 ~ 20mm medium coarse sand on the geotextile to form an infiltration filter layer, which can prevent the loss of planting soil;
5
Cover with planting soil of appropriate thickness

6
Protect the finished drainage board
After the drainage board is paved, it shall not be allowed to directly push and transport trolleys on the drainage board
Wood boards and berms shall be paved when transporting materials
Fill the soil while paving

Construction of drainage board planted on garage roof:
1
The construction base surface shall be solid, flat, smooth and free from looseness, sanding, warping, sharp convex, pothole, hollowing and other phenomena

2
The plastic drainage boards are overlapped and fully paved on the flat structural bottom plate, and the structural bottom plate surface does not need to be sloped

3
The Shiniu drainage board is laid by overlapping method, and the large and small fulcrums at the edge are overlapped with each other for 1 ~ 2 nodes

4
Fill the fulcrum gap of the plastic drainage board with C20 fine aggregate concrete, which is 1 ~ 2cm higher

5
After the concrete strength reaches more than 70%, tie the reinforcement ф 250, cast concrete C20, thickness 100, set warehouse joint, and set drainage ditch and sump in the bottom plate
