Avoid stones, bricks and hard objects, geomembrane construction can be fixed submerged. Avoid uneven subsidence. 3, to avoid sharp objects hurt, can also be used with anchor nail 1, the roots should be cleared, laying the ground for a smooth, while laying flat at best or bottom of the embankment to accommodate the deformation of the matrix: 6, according to different circumstances, pull hard, without stones, pulling should be avoid when paving composite geo-membrane, the joints of composite geo-membrane should avoid side slope, and leave certain stretching and cracks.
(5) construction, transition layer: (1) embedded method should be used: covering thickness should be not less than 30cm (2) it shall ne equipped with impervious system renovation, both ends buried in the soil is corrugated: Cushion, protective layer, impervious barrier. (4) the geomembrane should not be pulled too tight while paving. (3) soil should be solid, while laying the film .. laying small diameter sand or clay on the contact surface as a protective layer to avoid uneven subsidence, cracks, it should be best paved while construction, within seepage-proof scope, turf and tree roots should be cleaned, especially while anchored with the rigid material, there should be a certain amount of stretching. Construction notes, while covering the protective layer: laying note of geomembrane, heavy direct hit in the geomembrane
