Geotextile Composite Geomembrane의 일반 설치 방법
As the key medium of the anti-seepage structure, the geomembrane layer should meet the stress requirements during installation, because the leak control effect of geomembrane is related to its strength and thickness. Therefore, choose the appropriate thickness according to the design stress.
The 토목섬유 복합 지오멤브레인 heated with geotextile on one side or two sides has the features of high overall strength, tear resistance, anti-breaking and anti-piercing ability. The geotextile compounded on the membrane surface has supported and protected abilities.
For the leak control structure utilized with composite geomembrane, in general, the support layer and the protection layer can be simplified. For example, this geotextile composite geomembrane can be directly laid before the placement of concrete facing surface or the protective surface composed of the gravel cushion and the concrete slab. After laying this composite geomembrane, the medium coarse sand cushion can be directly laid.
The phenomenon that geotextile composite geomembrane is punctured is caused by the unenven subgrade, so it is important to prepare and maintain the civil works of subgrade.
General geotextile composite 지오멤브레인 installation method:
첫째, 서브 그레이드 처리
Subgrade should be prepared according to the design requirements, which is the key to ensuring the leak control performance. The substances including sharp stones, roots and other foreign subjects should be thoroughly removed, and subgrade is not allowed to be uneven. The prepared and maitained subgrade should be compacted by a tamper or a seesaw.
둘째, 누워
지오텍 스타일 복합 지오 멤브레인을 놓을 때 위에서 아래로 놓아야합니다. 지오컴포지트 사이, 지오멤브레인과 노반 사이의 겹침은 평평하고 단단해야 하지만 너무 세게 잡아당기면 안 되며 일반적으로 약간 느슨해야 합니다. 거품이 바닥에 있지 않도록 해야 합니다. 지오텍 스타일 복합 지오 멤브레인은 상대적으로 얇고 가볍기 때문에 보호 층이 놓이기 전에 바람에 날리기 쉽습니다. 그러므로, geotextile 합성 geomembrane는 한 번에 큰 지역으로 배치되면 안됩니다. 지오컴포지트가 잘 놓이면 토양의 보호 층을 놓습니다.
셋째, 관절
The joint has three methods of hot-melt welding, gluing and compacting, wherein the hot-melt welding has the best waterproof effect.
