The perfect product structure has improved the bidding ability for large-scale comprehensive projects. It is a high-tech enterprise integrating the R & D, production and sales of new polymer synthetic materials for geotechnical engineering. The geocell of professional geotextile manufacturers and geomembrane manufacturers is one of our main products. Geocell is widely used in erosion control, but it is more used in slope protection, dams, retaining walls, breakwaters and so on. Its principle is to increase fluidity, reduce rough erosion, prevent water pressure from increasing and eliminate concentrated erosion. The honeycomb restraint structure of the geocell can fix the filling material and limit the water pressure acting on it, so as to improve the fluidity. The honeycomb wall can drain water normally, but it can control the movement speed of the nest. Like thousands of micro dams, the concentrated water flow is dispersed into uniform and loose thin layers by the geocell.

1, from the bottom to the high extension, do not pull too tight, should leave 1.50% of the margin, in order to prepare for local subsidence stretching. Considering the actual situation of the project, the slope is laid from top to bottom.
2, adjacent two longitudinal joints should not be in a horizontal line, should stagger more than 1m each other;
3. The longitudinal joint should be more than 1.50m away from the dam foot and the bend foot, and should be located on the plane;
4, slope after bottom;
5, slope laying, film direction should be basically parallel to the maximum slope line.
1. Before laying geomembrane, the corresponding acceptance certificate of civil engineering shall be obtained.
2. Before geomemetic cutting, the relevant size should be accurately measured, and then cut according to the actual size, generally not according to the size shown, should be numbered piece by piece, detailed record in special form.
3. The laying of geomembrane should strive for the minimum weld, under the premise of quality assurance, as far as possible to save raw materials. It is also easy to ensure quality.
4. The lap width of the joint between the film and the film is generally not less than 10cm, usually so that the direction of the weld is parallel to the maximum slope, that is, along the slope direction.
5. Usually in corners and deformed sections, the joint length should be as short as possible. Except for special requirements, no weld shall be installed as far as possible on slopes with a slope greater than 1:6 and within 1.5 meters from the top slope or stress concentration area.
6. In the laying of geomembrane, artificial folds should be avoided. When the temperature is low, it should be tightened and paved as far as possible.
7. After the completion of geomembrane laying, walking on the membrane surface and moving tools should be reduced as far as possible. Objects that can cause harm to the impermeable membrane should not be placed on the membrane or carried on the membrane to walk, so as not to cause accidental damage to the membrane

2, filament or staple geotextile installation is usually lap, suture and welding methods. The width of suture and welding is generally more than 0.1m, and the lap width is generally more than 0.2m. Geotextiles that may be exposed for a long time should be welded or sutured.
The stitching of geotextiles
All stitching must be continuous (e.g., spot stitching is not allowed). Geotextiles must overlap at least 150mm before overlapping. Minimum stitching distance to selvage (exposed edge of material) is at least 25mm.
The best geotextile seams include 1 line of wired lock chain seam. The thread used for suturing shall be a resin material with a minimum tension of more than 60N and shall have chemical and uv resistance comparable to or exceeding geotextile.
Any “missing stitches” in the stitched geotextiles must be re-sewn in the affected areas.
Measures must be taken to prevent soil, particulate matter or foreign matter from entering the geotextile layer after installation.
The lap of cloth can be divided into natural lap, seam or welding according to the terrain and function.
Basic requirements for geotextile laying
1, the joint must intersect with the slope surface line; The horizontal joint shall be more than 1.5m away from the foot of the slope where it is balanced or where stress may be present.
2. On the slope, one end of the geotextile is anchored, and then the coil shall be put down on the slope to ensure that the geotextile is kept tight.
3, all geotextiles must be held down with sand bags, sand bags will be used during the laying period and reserved until the laying of the upper layer of material.
Technical requirements for geotextile laying
1, grass-roots inspection: check whether the grass-roots level, solid, if there is foreign matter, should not be properly handled.
2, test paving: according to the site situation, determine the size of geotextile, after cutting to test paving, cutting size should be accurate.
3, check whether the width of the pull is appropriate, lap joint should be smooth, moderate tightness.
4, positioning: use a hot air gun to bond the lap parts of the two geotextiles, and the distance between the bonding points should be appropriate.
5. When suturing the lap joint, the suture line should be straight and the stitching should be uniform.
6, after suturing should check whether the geotextile laid smooth, whether there are defects.
7, if there is no requirement of the phenomenon, should be repaired in time.
