Technical specification of short fiber needle punched nonwoven geotextile:
25 ~ 100
K x (10-1 ~ 10-3) (K = 1.0 ~ 9.9)
0.07 ~ 0.2
Nonwoven Geotextile Applications:
1) Filtration :
The filtration layer of the dykes, river canal, seacoast, concrete slope, retaining walls. At the same time of preventing the clay granule from passing, it allows the water and the gas pass through freely.
2) Separation :
The isolation of the railway dregs and the roadbed, roadbed and the soft base, surface of the airdrome and parking lot and the groundsill, different dam materials. It isolates the soil and the gravel of two kinds different granule pathway from the groundsill or other buildings.
3) Adding muscle :
The highway, railway, soil-stone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc in which distributes the earth stress, prevents the side-displacement of the earth body and improves the earth body stability.
4) Protection :
It prevents the bank from being washed out, protects the bank and the bottom, prevents the water and soil from being washed away.
- Q:Why calculate the amount of time to count a lot of cushion ah
- Cushion cushion, as the name suggests is the structure of the liner layer, mainly from the back cover of the role, generally in the engineering design drawings have a clear approach (material).
- Q:When the cushion is used, the thickness of the protective layer is not less than ()
- Basement roof: non-load protection layer generally use C20 fine stone concrete or reinforced concrete, the thickness of 50 ~ 80mm. The road, driving the protective layer is determined by design.
- Q:Can the cushion on the prefabricated board floor be dug?
- Surface layer without steel, do not bear the load, you can dig out
But sometimes the prefabricated floor above the surface layer with steel, to bear the load, this can not be removed!
To know how thick the cushion, in the local dig about
In general, to do leveling layer, can not be directly laid tiles
- Q:Foam concrete for the roof cushion generally do much bulk ah
- Foam concrete density grade is generally 300-1800kg / m3, commonly used foam concrete density grade 300-1200 kg / m3,
- Q:Do you need a cushion on the ground floor?
- In addition to wood also buy wooden side, used as the main beam, beam and pillars.
The ground is also recommended to raise, raise the place also to beam and pillars
The number of boards to be based on your design to determine the ground practice, roof practices will affect the number of wood
- Q:Can the floor tiles be removed from the cement mats on the prefabricated board floor?
- Prefabricated board surface is best to do some cement mortar cushion, can prevent the decoration of the water generated to the downstairs.
- Q:Large area ground concrete cushion seam Why is the separation of joints generally concrete
- First, the rigid waterproof layer in a large area of construction, by the external force, temperature, humidity changes, structural layer deformation and other factors prone to cracking, leading to leakage, the design should consider the deformation of the waterproof layer to take the necessary Structural or structural measures to avoid and mitigate the cracking of the waterproofing layer to achieve the desired waterproofing effect.
- Q:Basement cushion waterproof
- Fourth, improve the waterproof performance:
1, Aggregate graded concrete, is the use of different aggregates of the aggregate and improve the content of cement mortar in the concrete, so that the mortar is filled between the aggregate, thus blocking the aggregate is not dense between the seepage channel , Improve water resistance;
2, plus concrete, is added in the concrete air conditioner or dense agent to improve the impermeability.
- Q:The roof cushion is waterproof on the slope roof
- When the moisture generated by the ice dam into the external walls of the gap, the walls and insulation layer will become damp, which is the ideal environment for the breeding of mold.
- Q:Why do the basics of the cushion waterproofing
- Base cushion waterproofing is not contact with the soil (Ying water) to prevent water into the cushion, but in the cushion and the base of the bottom of the contact, in fact, is the basis of the bottom of the waterproof.
