Firstly, the anchorage ditch should be excavated deep enough to prevent the composite membrane from sliding.
If the length of the steep slope is too long, an anchor ditch must be set in the middle to prevent the damage of the composite membrane due to the excessive tension of the steep slope, which will affect the anti-seepage effect.
Fixing the composite membrane on the slope briefly introduces the use of anchor ditch and sandbag for fixation.
However, the construction in mountainous and hilly areas will be determined according to the terrain.
How to repair it after damage can give full play to its due anti-seepage effect is concerned by many people.
Generally, the geotextile is treated by hand-held sewing machine.
The repair methods of geomembrane and geotextile are different.
I hope it can provide help for you.
After the composite geomembrane is damaged, first check the damaged part and damaged area to facilitate the formulation of corresponding repair measures.
In the process of laying rivers, artificial lakes and reservoirs in plain areas, the slope is relatively slow, and the laying and welding are relatively simple and fast.
If the damaged part of the composite geomembrane is repaired at the place where it has been compounded, it is relatively complex.
Sandbags shall be used for compaction every 6 meters, unless timely backfilling can avoid damaging the composite membrane by strong wind.
The geomembrane manufacturer has sorted out the construction and fixation methods of composite geomembrane on steep slope, I hope it will help you.
If there is a flat place in the middle of the slope, an anchor ditch can be set or fixed with sandbags, and the bottom should also be compacted with sandbags.
Because the composite geomembrane structure is a layer of Geomembrane in the middle and a layer of geotextile is attached on both sides, it can not only meet the basic anti-seepage requirements, but also strengthen and protect the foundation and the surface of the laying object.
The repair of geotextile is relatively simple.
The geomembrane manufacturer below will introduce how to repair the damaged composite geomembrane.
Without adhesive tape, the film with an area slightly larger than the damaged part can be cut, and hot-melt bonding shall be carried out with a hot-air welding gun.
Composite geomembrane is used in reservoir, artificial lake, river and other projects to prevent seepage and protect slope.
The damaged part is at the edge (i.e.
This kind of material with a wide range of consumption will inevitably be damaged in the process of transportation, construction and laying.

Generally, the middle membrane of the composite geomembrane is thin.
It is OK to bond after grinding.
As a kind of geosynthetic anti-seepage material, composite geomembrane is used in many engineering fields, mainly playing the role of isolation, anti-seepage and reinforcement.
This method has low construction cost and simple operation.

Generally, the sealing machine is used for sewing, and the damaged part can be sewn with the sealing machine.
The difference is that the geomembrane and impervious membrane can be welded directly.
Geomembrane is generally welded by double pass welding machine, and a small number can also be bonded by special glue for Geomembrane or special tape.
Generally, sandbags shall be used to press, and the welding of geomembrane and the sewing of geotextile shall be carried out.
For the composite geomembrane, the geotextile needs to be treated after the membrane is welded.
The composite geomembrane is generally laid from the top of the slope to the bottom of the slope.
Therefore, the fixation of composite geomembrane on steep slope is a difficult problem.
The two adjacent composite membranes shall be overlapped for 10 cm, and the lower end shall also be fixed.
After finding the damaged part, look at the size of the damaged surface.
During laying, the edge of the composite membrane shall be buried in the anchor ditch and fixed.
Where the area is small, it is necessary to use a grinder to grind off the exposed geomembrane part of the surface geotextile.
It not only has a good anti-seepage function of geomembrane, but also has the function of reinforcement and soil consolidation of geotextile.
Just cut off the damaged part directly.
the separated part of membrane and cloth) such repair is relatively simple.
A single side can be used for a seam or a small hole Adhesive tape shall be used for bonding.
If there is no buffer zone in the middle, you have to use sandbags to stack at the bottom until it is above the middle.
When grinding, avoid damaging the middle geomembrane, The grinding area shall be larger than the area of the damaged surface.
If the damaged part is too large, it is not necessary to repair it.
The fixing method of composite geomembrane steep slope is the same as that of geomembrane and impervious membrane.
