电厂灰坝渣场防渗工程土工膜的铺设方法- 泰安瑞恒
土工膜的铺设方法,泰安市瑞恒土工材料有限公司提醒您:1. 铺设土工膜前应由土建工程相应的合格验收证明文件。
2.土工膜裁切之前,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,详细记录在表格上。
3.铺设土工膜时应力求焊缝少,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。
6.土工膜在铺设中,应避免产生人为褶皱,温度较低时,应尽量拉紧,铺平。
7.土工膜铺设完成后,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,均不应放在土工膜上或携带在膜上行走,以免对膜造成意外损伤。
Ash dam slag yard engineering of geomembrane laying method - the most professional Tai'an ruiheng!
Geomembrane laying method, Tai'an City Ruiheng geotechnical material limited company to remind you:
1 laying geomembrane before the civil engineering a corresponding qualification and acceptance certificate.
2 - geotechnical membrane cut before, should measure the correlation dimension, then according to the actual cutting, the general should not be to press the cutting size, should one piece number, recorded in detail in special form.
3 laying geomembrane should strive to weld the least, under the premise of guaranteeing quality, as far as possible to save raw material. It is also easy to ensure quality.
4 membrane and membrane joints between lap width not less than 10cm, usually make welds arrangement direction parallel to the maximum slope, along the slope direction.
Normally in the corner and deformity of 5 lots, should be the length of the joint to reduce short. 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 geotechnical membrane in laying, should avoid artificial fold, when the temperature is low, should be taut,paving.
7 geomembrane laying is completed, should be minimized in the membrane surface running, move tool, that can cause harm to the impermeable membrane object, shall not put in the film or carried in the film walk, so as to avoid accidental injury of membrane.
