Needle geotextile production equipment from Xidesibin Fort Dillow's introduction, can produce weight per square meter of 100g-1000g, width of 2.0m-6.3m, single-layer or multilayer (reinforcement geotextiles), the annual output of 10 million square meters

 1 the use of raw materials
This company produces high-quality needle geotextile are mainly based polyester staple fiber (fiber 4-9dtox, length 50-76mm) can also be produced according to user requirements polypropylene, polyamide, polyvinyl alcohol or mixed fibers needle geotextile.

 

2 needle geotextile function, role and impact of parameters

A Isolation

Namely the use of geotextiles with different physical properties (particle size, distribution, consistency and density, etc.) building materials (such as soil and sand, sand and gravel, soil and concrete, etc.) in isolation. Between two or more materials, so that no loss, no mixing, maintaining the overall structure and function of materials to make structures, load bearing capacity strengthening.

B Filter

When the water from the washing of soil into the coarse material layer material, the use of needle geotextile good air permeability and water permeability, so that flow of water through, while the effective closure of soil particles, spun yarn, small stones, so as to maintain the stability of soil and water engineering .

C Drainage

Acupuncture geotextile hydraulic conductivity is a good material, which can be formed within the soil drainage channels within the structure of the soil excess liquids and gases outside.

D reinforced

The use of acupuncture to enhance soil geotextile tensile strength and resistance to change capacity, and increasing the stability of building structures in order to improve soil quality.

E protective

Effectively focus on stress proliferation, transfer, or decomposition, to prevent the destruction of soil by the external force.

F closed

Acupuncture geotextile and other materials (mainly asphalt or plastic membrane) complex, in the formation of impermeable soil compartment. (Mainly used for road resurfacing, patching, etc.)

3 the application
Because acupuncture has a separation geotextile, filtration, drainage, protection, reinforced, closed six major functions, it can be widely used in railways, highways, sports stadiums, dams, hydraulic construction, tunnel, along the beach path, land reclamation, environmental protection and other projects
