ジオテキスタイル複合ジオメンブレンの一般的な設置方法
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 ジオテキスタイル複合ジオメンブレン 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 ジオメンブレン installation method:
まず、路盤処理
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.
第二に、敷設
ジオテキスタイル複合ジオメンブレンを敷設するときは、上から下に敷設する必要があります。ジオコンポジット間、およびジオメンブレンと路床の間のオーバーラップは平らでタイトである必要がありますが、きつく引っ張りすぎず、通常はわずかに緩くする必要があります。泡は底から防ぐ必要があります。ジオテキスタイル複合ジオメンブレンは比較的薄くて軽いため、保護層が敷設される前に風に吹き飛ばされやすいです。したがって、ジオテキスタイル複合ジオメンブレンは、一度に広い面積で展開しないでください。ジオコンポジットが十分に敷設されたら、土壌の保護層を敷設します。
第三に、ジョイント
The joint has three methods of hot-melt welding, gluing and compacting, wherein the hot-melt welding has the best waterproof effect.
