Métodos generales de instalación de geomembrana compuesta geotextil
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 geomembrana compuesta geotextil 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 geomembrana installation method:
Primero, el tratamiento de subrasante
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.
En segundo lugar, la colocación
Al colocar la geomembrana compuesta geotextil, debe colocarse de arriba a abajo. La superposición entre los geocompuestos, y entre la geomembrana y la subrasante debe ser plana y apretada, pero no debe tirarse demasiado, generalmente debe estar ligeramente floja. Se debe evitar que las burbujas salgan de la parte inferior. Debido a que la geomembrana compuesta geotextil es relativamente delgada y liviana, es fácil que el viento la sople antes de que se coloque la capa protectora. Por lo tanto, la geomembrana compuesta geotextil no debe implementarse con un área grande a la vez. Coloque la capa protectora del suelo una vez que el geocompuesto esté bien colocado.
En tercer lugar, la articulación
The joint has three methods of hot-melt welding, gluing and compacting, wherein the hot-melt welding has the best waterproof effect.
