Geotextile production process
Geotextile is widely used in civil engineering materials, with filtration, isolation, reinforcement, protection and other functions, its production process includes raw material preparation, melt extrusion, mesh rolling, draft curing, winding packaging and inspection steps, need to go through multiple links of processing and control, but also need to consider its environmental protection and durability and other factors. Modern production equipment and technology have been widely used, making the production efficiency and quality of geotextiles have been significantly improved.

1. Raw material preparation
The main raw materials of geotextile are polyester chips, polypropylene filament and viscose fiber. These raw materials need to be inspected, arranged and stored to ensure their quality and stability.

2. Melt extrusion
After the polyester slice is melted at high temperatures, it is extruded into a molten state by a screw extruder, and polypropylene filament and viscose fiber are added for mixing. In this process, the temperature, pressure and other parameters need to be precisely controlled to ensure the uniformity and stability of the melting state.

3. Roll the net
After mixing, the melt is sprayed through the spinneret to form a fibrous substance and form a uniform network structure on the conveyor belt. At this time, it is necessary to control the thickness, uniformity and fiber orientation of the mesh to ensure the physical properties and stability of the geotextile.

4. Draft curing
After laying the net into rolls, it is necessary to carry out draft curing treatment. In this process, the temperature, speed and draft ratio need to be precisely controlled to ensure the strength and stability of the geotextile.

5. Roll and pack
The geotextile after draft curing needs to be rolled up and packed for subsequent construction. In this process, the length, width and thickness of the geotextile need to be measured to ensure that it meets the design requirements.

6. Quality inspection
At the end of each production link, the quality of geotextile needs to be inspected. The inspection contents include physical property test, chemical property test and appearance quality test. Only geotextiles that meet the quality requirements can be used in the market.

Geomembrane application technology
Geomembrane is a kind of material widely used in engineering projects, which has the functions of seepage prevention, isolation and reinforcement. This paper will introduce the application technology of geomembrane, including selection, laying and maintenance.

1. Select geomembrane
It is very important to choose the suitable geomembrane. Here are some key points to choose geomembrane:
- Material properties: Geomembranes are divided into different materials, such as high density polyethylene (HDPE) and linear low density polyethylene (LLDPE). Select the appropriate material according to the engineering requirements Characteristic.
- Thickness: Select the appropriate thickness according to the needs of the project. The thickness of the geomembrane is usually 0.3mm to 2.0mm.
- Impermeability: Ensure that the geomembrane has good impermeability to prevent water in the soil from penetrating into the project.

2. Geomembrane laying
The laying of geomembrane needs to follow certain steps and techniques:
- Land preparation: Ensure that the land where the geomembrane is laid is level and clean, and sharp objects and other obstacles are removed.
- Laying method: Geomembrane can be covered laying or folding laying. Select the appropriate laying method according to the project requirements.
- Joint treatment: Joint treatment is performed at the joint of the geomembrane to ensure that there is no leakage at the joint.
- Fixing method: Use fixed parts to fix the geomembrane and ensure that it is closely attached to the ground.

3. Maintenance of geomembrane
Maintenance of geomembrane can extend its service life and function:
- Cleaning: Regularly clean the surface of the geomembrane to remove dirt and debris to maintain its impermeability.
- Inspection: Regularly check whether the geomembrane is damaged or aging, repair or replace the damaged part in time.
- Avoid sharp objects: Avoid sharp objects from touching the geomembrane to prevent damage.

In Summary
The application technology of geomembrane includes selecting suitable geomembrane, laying geomembrane correctly and maintaining geomembrane regularly. Reasonable application of geomembrane can effectively improve the functions of seepage prevention, isolation and reinforcement of engineering projects, and provide guarantee for the smooth progress of engineering.

Geomembrane, as an efficient anti-seepage material, plays a vital role in water conservancy projects. Its excellent anti-seepage performance, light and easy construction characteristics and relatively low cost make geomembrane become an indispensable part of water conservancy projects.

First of all, in the construction of reservoirs, geomembrane can play a very good anti-seepage role. Because reservoirs are usually built in valleys or low-lying areas, the geological conditions are more complex, so effective measures need to be taken to avoid leakage between the bottom of the reservoir and the surrounding rock. The use of geomembrane can effectively solve this problem, and can also improve the safety and stability of the whole reservoir.

Secondly, it is also necessary to use geomembrane to strengthen the anti-seepage effect during the construction of levees. A dike is a man-made structure whose main purpose is to protect the downstream area from flooding. However, in the construction process, there will be many unpredictable factors leading to loopholes, at this time, it is necessary to use geomembrane for remedial measures.

Third, in the river and channel governance, geomembrane also has a wide range of applications. Rivers and channels are very important components of water conservancy projects, they can not only regulate water flow, protect farmland and urban infrastructure, but also improve the ecological environment of the entire region. However, in the governance process will encounter some difficult problems, such as loopholes, landslides and so on. At this time the use of geomembrane can be a good solution to these problems.
