藕池防渗地膜怎么铺设Ouchi impervious plastic film how laying
藕池防渗膜的铺设:
1.铺设藕池防渗膜前应由土建工程相应的合格文件。
2.防渗膜裁切之前,应该准确丈量其相关尺寸,然后按实际裁切,一般不宜按图示尺寸裁切,应逐片编号,详细记录在专用表格上。

3.铺设藕池防渗膜时应力求焊缝*少,在保证质量的前提下,尽量节约原材料。同时也容易保证质量。
4.膜与膜之间接缝的搭接宽度一般不小于10cm,通常就使焊缝排列方向平行于*大坡度,即沿坡度方向排列。

5.通常在拐角及畸形地段,应是接缝长度尽量减短。除特殊要求外,在坡度大于1:6的斜坡上距顶坡或应力集中区域1.5米范围内,尽量不设焊缝。 藕池防渗地膜怎么铺设
6.藕池防渗膜在铺设中,应避免产生人为褶皱,温度较低时,应尽量拉紧,铺平。
7.藕池防渗膜铺设完成后,应尽量减少在膜面上行走、搬动工具等,凡能对防渗膜造成危害的物件,均不应放在膜上或携带在膜上行走,以免对膜造成意外损伤。
The lotus pool paved impermeable membrane:
1 lotus pool before laying impermeable membrane by civil engineeringcorresponding qualification documents.
Before the 2 impermeable membrane cutting, should accurately measurethe correlation dimension, then according to the actual cutting, the general should not according to graphic cutting size, should one piece number, recorded in detail in special form.
3 laying Ouchi impervious membrane should be sought to weld the least,under the premise of guaranteeing quality, to save raw materials. It is also easy to ensure quality.
Between the 4 membrane and overlapping width of seam is藕池防渗地膜怎么铺设 generally not less than 10cm, usually make welds arrangement parallel to the direction of maximum gradient, namely along the slope direction.
5 normally in the corner and deformity of the lot, should be as far as possible to shorten the length of the joint. Except special requirement, the slope is greater than 1:6 slope away from the top of slope and the stress concentration area within 1.5 meters, as far as possible without weld.
6 lotus pool impervious membrane in laying, should avoid artificial fold,the temperature is low, should be taut, paving.
7 lotus pool impervious membrane laying is completed, should minimize the walk, move the tool on the membrane surface and so on, all candamage caused by objects impervious membrane, should not carry it or walk on the membrane in the membrane, so as to avoid accidental injury of membrane.
