The living environment of the people is constantly being optimized, and the construction of urban infrastructure is continuously improving, which has promoted the rapid development of the environmental protection industry. So today, we mainly talk about what role the geomembrane in the landfill plays in the project.

Firstly, geomembranes are classified into smooth geomembranes, composite geomembranes, column-point geomembranes, and rough geomembranes. Each of these products has its own characteristics and is suitable for different engineering applications. Today, we will focus on the functions and raw materials of smooth geomembranes.

Geomembranes cannot be used as load-bearing components. Generally, they are required to be able to adapt to construction stress and slightly larger uneven settlement. However, an important requirement for the function of geomembrane is that it should be impermeable, that is, it should not be punctured and fail under the action of water pressure.

Geomembrane is currently widely used in highway pavement maintenance, stadiums, dam protection, isolation of hydraulic structures, coastal tidal flats, reclamation and other projects. Here is a brief introduction to the reasons for adding a protective layer to the product during construction.

With the application effectiveness of geomembrane in water conservancy and emergency rescue projects, this low-cost and well-applicable anti-seepage material has gained the attention of technicians in many engineering projects, and its application scope and methods are also gradually expanding.

Geocells are a mesh structure of high-strength HDPE wide bands formed by strong welding surfaces. It is flexible and can be folded for transportation, and when in use, the well can be opened and filled with earth, stone or concrete to form a structure with strong lateral restraint and high rigidity. It can be used as a cushion to deal with the bearing capacity of weak foundations, laid on slopes to form slope protection structures, or used to build retaining structures, etc.

Plastic blind drain is frame structure that is formed by mutual joining of silks of modified polypropylene after melting and a layer of geotechnical cloth is wrapped on its outside. Clean water after filtering by geotechnical cloth enters plastic blind drain and is discharge. Section of permeable pipe can be made into various shapes according to project need, mainly including rectangle and circle.

Flexible permeable pipe is high pressure resistance flexible structure formed by using anti-rust spring ring to support pipe body, uses non-weaving cloth liner for filtering and makes mud, sand and foreign object unable to enter pipe so as to reach the effect of purifying permeation water, Polypropylene silk wrapping coverage layer and spring steel ring pipe body form an integral part that has very good omnidirectional permeation function, permeation water can enter the pipe smoothly, mud, sand and foreign object are blocked outside pipe so as to realize the purpose of water permeation, filter and drainage.

Series 1: Short fiber needle punched nonwoven earthwork cloth Operation and description Changhong short fiber needle punching non-woven earthwork cloth is produced by using outstanding terylene or polypropylene short fiber as raw material and after carding net laying needle punching processing.

After laying the high-density polyethylene geomembrane, a high-strength waterproof layer can be formed. Prevent sewage, rainwater and other substances from seeping into the ground. And it has certain characteristics such as puncture resistance, wear resistance, tear resistance and fatigue resistance.
