土工布铺设施工程序及工艺流程

Geotextiles laying facilities engineering program and process

1、储存、运输和处理土工布

1, storage, transportation and treatment of Geotextile

土工布卷在铺设展开前要避免受到损坏。土工布卷应该堆放在平整不积水的地方,堆高不超过四卷的高度,并能看到卷的识别片。土工布卷必须用不透明材料覆盖以防紫外线老化。在储存过程中,要保持标签的完整和资料的完整。

The geotextile volume in laying to avoid damage before expansion. The geotextile volume should be stacked in neat and not stagnant water, high pile of not more than four volumes of height, and can see the identification sheet roll. The geotextile volume must use the opaque material covered with anti ultraviolet aging. During storage, to maintain the integrity and the integrity of information label.

在运输过程中(包括现场从材料储存地到工作地的运输),土工布卷必须避免受到损坏。

In the process of transportation (including the site from the material storage to the work of the transport), geotextile volume must avoid damage.

受到物理损坏的土工布卷必须要修复。受严重磨损的土工布不能使用。任何接触到泄漏化学试剂的土工布,不允许使用于。

Physical damage by geotextile volume must repair. By geotextile can badly worn use. Any contact to the leakage of chemical reagents geotextile, are not allowed to use in.

2、土工布的铺设方法:

Method 2, laying geotextile:

2.1用人工滚铺;布面要平整,并适当留有变形余量。

2.1 using artificial rolling shop; cloth should be smooth, and keeping proper deformation allowance.

2.2长丝或短丝土工布的安装通常用搭接、缝合和焊接几种方法。缝合和焊接的宽度一般为0.1m以上,搭接宽度一般为0.2M以上。可能长期外露的土工布,则应焊接或缝合。

2.2 filament or staple fiber geotextile installation methods, usually welded lap suture and. Suture and weld width is generally above 0.1M, lap width is generally more than 0.2M. The possible long-term exposure of geotextiles, should be welded or suture.

2.3土工布的缝合

Suture in 2.3 Geotextiles

所有的缝合必须要连续进行(不允许点缝)。在重叠之前,土工布必须重叠不少于15cm。缝针距离织边(材料暴露的边缘)至少是2cm

All of the stitching must be continuous (not allowed to stitch). In the overlap before, geotextile must overlap is not less than 15cm. Needle distance selvage (material exposed edge) is at least 2cm.

缝好的土工布接缝最少包括1行叉线锁口链形缝法。用于缝合的线应为最小强力超过60N的树脂材料,并有与土工布有相当或超出的抗化学腐蚀和抗紫外线能力。

Sewing geotextile seam good includes at least 1 for fork line locking chain stitch. For suture line should be as minimum strength more than 60N resin material, and there is a considerable or beyond the resistance to chemical corrosion and anti ultraviolet ability and geotextile.

土工布上的漏针必须在受到影响的地方重新缝接。

On the geotextile "drain pin" must be in the affected local re seam.

采取相应的防护措施,避免在铺设后,土壤、颗粒物质或外来物质进入土工布层。

Take the corresponding protective measures, avoid after laid, soil, particulate matter or foreign substances into the geotextile layer.

2.4在施工中,复合土工膜下层的土工布采用自然搭接,复合土工膜上层的土工布应采用缝接或热风焊接。热风焊接是首先的长丝土工布的连接方法,即用热风枪对两片布的连接处瞬间高温加热,使其部分达到融熔状态,并立即使用一定的外力使其牢牢地粘合在一起。在潮湿(雨雪天)天气不能进行热粘连接的情况下,土工布应采取缝合连接法,即用专用缝纫机进行双线缝合连接,且采用防化学紫外线的缝合线。

2.4 in the construction of composite geomembrane, geotextile with lower natural overlap, composite geomembrane upper geotextile should be used or hot air welding seam. Hot air welding method is connected with the first filament geotextile, i.e. using a hot-air gun of two piece of cloth is connected at the moment high temperature heating, the part reaches the melting state, and immediately the use of certain external forces firmly bonded together. In wet weather can not be (Yu Xuetian) hot sticking connection, geotextile should take the suture connecting method, namely using special sewing machine for a double stitch suture line connection, and the use of anti chemical uv.

缝合时最小宽度10cm,自然搭接时最小宽度为20cm、热风焊接时最小宽度为20cm

When sewing the minimum width of 10cm, natural lap width is 20cm, the minimum width of 20cm hot air welding.

2.5对于缝合,要采用质量与土工布相同的缝合线,缝合线要采用抗化学破坏和紫外光照射能力更强的材质。

2.5 for suture, should use quality and earthwork cloth the same suture, suture to adopt anti chemical damage and UV irradiation ability stronger material.

2.6土工布铺设完毕由现场监理工程师认可后方可进行下一步工序。

2.6 geotextiles laying is completed by the on-site supervision engineer approval rear can proceed to the next step in the process.

2.7膜上下两层土工布在有锚固槽的部位都应与土工膜一同埋入锚固槽内。

The 2.7 film soil under two layers of cloth should be in the position of the anchoring slot with geomembrane together into the anchorage slot.

3、土工布铺设的基本要求:

The 3 basic requirements, Geotextiles laying:

a、接缝须与坡面线相交;与坡脚平衡或可能存在应力的地方,水平接缝的距离须大于1.5m

A, joint must intersect with the line of slope; and the existence of stress place toe balance or may, horizontal joint distance must be greater than 1.5m.

b、在坡面上,对土工布的一端进行锚固,然后将卷材沿坡面放下以保证土工布保持拉紧的状态。

B, on the slope, anchoring one end of geotextiles, and then roll along the slope down to ensure that the earthwork cloth taut state.

c、所有的土工布都须用砂袋压住,砂袋将在铺设期间使用并保留到铺设上面一层材料。

C, all of the geotextile are required to use sandbag pressing, sand bag will be used during the laying period and retained to the laying of the top layer material.

4、土工布铺设工艺流程

4, Geotextiles laying process

基层检查―――现场丈量―――土工布裁剪―――铺设―――缝合(或热粘合)――-检查―――是否符合要求―――填写施工记录

Grass-roots examination -- field measurement -- geotextile cutting -- laying -- suture (or thermal bonding) whether -- check -- meet the requirements -- fill construction record

5、土工布铺设工艺要求

5.4定位:用热风枪将两幅土工布的搭接部位粘接,粘接点的间距应适宜。

5.4 location: two pieces of geotextile overlapping part of bonding with a hot-air gun, spacing bonding point should be appropriate.

5.5对搭接部位进行缝合时缝合线应平直,针脚应均匀。

Suture of the overlapping part 5.5 suture line should be straight, pins should be uniform.

5.6缝合后应检查土工布是否铺设平整,是否存在缺陷。

5.6 after suture should check whether the geotextile laid flat, the existence of defects.

5.7如存在不合要求的现象,应及时进行修补。
