Geotextile generally refers to long (short) silk cloth, also known as non-woven fabric, because it is made by non-woven process.

The joint must intersect with the slope line; If there is balance or possible stress with the foot of the slope, the distance of the horizontal joint shall be greater than 1.5m.

During construction, the foundation surface shall be leveled with small-diameter sand or clay, and then the geomembrane shall be laid.

Lifting Anchor

The width of welding seam shall not be less than 100 times and the width of natural lap shall not be less than 200 times.

One cloth and one film refers to a layer of geotextile attached with a layer of PE film.

Geotextile is used as the protective layer of geomembrane to prevent the protective layer from being damaged.

Because these two kinds of woven fabrics, it is not specified that geotextile is non-woven.

Production process of short silk cloth and long silk cloth short silk cloth takes short fiber polyester or polypropylene as raw material, enters the storage box through disassembly machine, elastic machine, and then paves four to five layers of mesh, and then pulls out and forms a blade after pre pricking, barbed and main needle.

In the construction process, try to prevent the stone from directly hitting the geomembrane, lay the protective film and construct the protective layer.

Because the fiber has tear resistance and good main functions: filtration, water filtration and reinforcement, the specifications range from 100 g / m2 to 800 g / m2.

4.

A layer of excess layer of about 10cm is paved on the geomembrane paved with fine sand or clay.

The geomembrane should not be too tight.

20 ~ 30cm blocks (or concrete precast blocks) are anti scour protective layers.

Two cloth and one film refers to a layer of PE film sandwiched between the double-layer geotextile.

The silk is made into a net, and then through pre pricking and re needling, and finally cut and stretched.

In the project, the installation of short wire geotextile can adopt three methods: natural lap method, welding seam method and welding.

The geomembrane at the boundary shall be prevented from leaking into the air for a long time as possible, otherwise it will cause certain damage due to human factors, which must be paid attention to…

By coincidence, the nonwoven fabric coincided with the 150 mm geotextile The stitch is at least 25 mm from the edge of the tissue (the leakage edge of the material).

Geomembrane is divided into 0.3mm ~ 2.0mm (thin and thick), non-standard and national standards.

After installation, corresponding countermeasures shall be taken to prevent the soil layer, particulate organic matter or foreign organic matter from entering the non-woven geotextile layer.

According to the landform and its application, the connection of cloth can be divided into natural connection, sewing or welding.

In order to reduce ultraviolet radiation and improve the anti-aging ability, buried method is adopted.

A relatively wide margin shall be reserved at the boundary to connect the soil more closely and avoid leakage caused by improper connection, loss of water resources or damage to the soil by some pollutants.

Geotextile also includes filament woven (filament woven) and woven fabric.

Long silk cloth is made of new polyester chip particles through high-temperature melting and plasticity.

Generally speaking, it refers to the composite material bonded by geotextile (woven fabric machine or plastic barrel) and PE film.

The main material is polyester fiber, which has excellent water permeability, filtration, durability and deformation adaptability, and has good flat drainage capacity.

Geomembrane is also called waterproof layer geotextile.

The sewn nonwoven geotextile seam is sewn by a thread bolt chain The thread used for sewing must be a resin material with a minimum tension greater than 60N, and has the same or stronger resistance to organic chemical corrosion and ultraviolet light as non-woven geotextile.

3.

When connecting the composite geomembrane with the surrounding structure, expansion bolts and steel reinforcement shall be used and combined with emulsified asphalt (2mm thick) to prevent leakage.

The price is 3 ~ 18 yuan per square meter.

Two membranes and one cloth refers to a layer of geotextile sandwiched between two PE membranes.

When using soil connections, first ensure that there is no damage to the geomembrane, and then plug it with a more sealed method.

The technical and technical requirements for laying short wire geotextile are as follows: 1 Submit detailed geotextile laying drawings and schedule to the engineer before laying short wire geotextile; 2.

The “water leakage needle” on other sewn non-woven geotextiles must be sewn again in the adversely affected areas.

The soil at both ends is wavy.

The geotextile surface shall be flat and the deformation shall be reserved.
