Construction method: of Composite Geomembrane with PET Non-woven Geotextile: the composite geomembrane is directly laid on the surface of the embankment, the upper part is covered with 10 cm thick sand cushion, and the surface is 10 cm thick concrete. 

  1. Composite Geomembrane with PET Non-woven Geotextile construction technology principle: composite geomembrane is a kind of geosynthetics, which has good seepage control effect. The composite geomembrane is laid on the slope surface which needs to be impervious to seepage. The sand cushion and concrete are laid on it, and the top layer concrete of the dike top is formed as a whole sealing system.

2. The construction process of Composite Geomembrane with PET Non-woven Geotextile: before the composite geomembrane is laid, the filling of the canal and the finishing of the slope surface are finished, the level of the slope is evenness. The compactness reaches the design requirements and the composite geomembrane can be laid after the inspection and acceptance by the supervision engineer. The construction preparation of the

3. Composite Geomembrane with PET Non-woven Geotextile: 1) cleaning the slope of the embankment, leveling the ground, clearing all the sundries, filling the slope and ramming the slope under the slope, providing a working face for the composite geomembrane laying. 2) in order to facilitate the construction and guarantee the quality of the splicing, the composite geomembrane should be used as wide as possible to reduce the amount of stitching. Before the construction, the width of the composite geomembrane should be made according to the width of the composite geomembrane. The site length needs to be cut in units and spliced into the size of the block, which is rolled on the steel pipe and moved to the working face. Set. 

4. The laying method of Composite Geomembrane with PET Non-woven Geotextile. The composite geomembrane is laid on the bottom of the canal. The slope is paved with two parts. Paving method: rolling horizontally along the axis of the channel. After the slope is laid on the slope, it is rolled up from the axis of the slope and connected with the composite geomembrane at the bottom of the canal. 5. composite geomembrane laying technology requirements: the laying should be carried out in the dry and warm weather, in order to facilitate the splicing and prevent the stress concentration, the composite geomembrane is laid in a wave relaxation mode, and the surplus degree is about 1.5 after the spread, and the composite geomembrane is flat with the slope, without sudden wrinkles and construction personnel. Should wear plain cloth shoes or soft rubber shoes, strictly prohibit wearing nail shoes, so as not to step on the geomembrane. If the geomembrane damage is found during construction, it should be repaired in time. 6. composite geomembrane splicing 1) welding with hot-melt welding construction, splicing including geotextile joints. Geomembrane welding, in order to ensure welding quality, welding should be done as far as possible in the factory, but for the convenience of construction, the width of the composite geomembrane should not be too wide, splicing in the construction site.
