产品介绍

土工网是高密度聚乙烯(HDPE)加抗紫外线助剂加工而成,具有抗老化、耐腐蚀等特征。公路、铁路路基中使用可有效地分配荷载,提高地基的承载能力及稳定性,延长寿命。在公路边坡上铺设,可防止滑坡,保护水土,美化环境。水库、河流堤坝防护铺设可有效防止塌方,在海岸工程中用其柔韧性好、渗透性好的特点来缓冲海浪冲击能量。铺设土工网可加固路面,防止反射裂缝的发展; 土工网作为挡土墙体填土中的加筋材料,可分散土体应力,限制侧向位移,增强稳定性; 用土工网制成石笼用于堤坝、岩石表面的防护,可防止侵蚀、避免塌方、和水土流失。

产品特点

1、增强路面稳定性,防止裂纹;

2、可承受较大的变载荷;

3、可防止翻浆造成的路面裂纹;

4、可减少路面材料用量,加快施工速度。

产品用途

用于路基增强,使粒状填料与网格互相锁合在一起,形成稳定的平面,提高路基稳定性;防止填料下陷及反射裂缝的发展,并可将垂直载荷分散;地理条件恶劣地区可采用多层增强。适用于江河堤坝防护,海岸治理,隧道工程及防波堤导流坝的铺设等。

3.Geonet

Product Description

Plastic geonet is a kind of network structural material eith HDPE or other high-molecular polymer as primary raw material adding a certain auxiliary materials such as anti-UV agent. It can distribute load effectively to be used in roadbed of road and rail-way, enhance bearing capacity and stability of roadbed, and prolong using life. It can prevent rock fall, protect water and earth, beauty environment to place geonet in slope of road and railway. It can prevent landslide to place geonet in dike of reservoir and river. In coastal engineering, it can relieve impacting energy of waves with the characteristics of flexibility and permeability. Laying the geonet can strengthen the road surface and prevent the development of reflective cracks. The geonet is used as a reinforcing material in the retaining wall filling, which can disperse the soil stress, limit lateral displacement and enhance stability. It is used for the protection of dams and rock surfaces to prevent erosion, landslides and soil erosion.


Product Features

1.Enhance road stability and prevent cracks;

2. Can withstand large variable loads;

3. It can prevent pavement cracks caused by slurry turning;

4. It can reduce the amount of pavement materials and speed up the construction.


Product Application

It is used to reinforce the roadbed, so that the granular filler and the grid are locked together to form a stable plane and improve the stability of the roadbed; prevent the subsidence of the filler and the development of reflective cracks, and disperse the vertical load; Layer enhancement. It is suitable for river dam protection, coast management, tunnel engineering and laying of breakwater diversion dams.

三维土工网垫的使用方法:

1) 施工时可用小竹竿或小木棍穿于整卷网垫中,顺势拉出网垫,四周用竹钉,木钉或用塑料钉钉住,钉子间距30cm,每平-米10只钉子。 

2)钉子的长度一般为15cm(距离地面),疏松地表则应加长钉子长度,在高坡铺设时,上坡使用的钉子长度应长于下坡的长度。 

3)地形突变处或地形较复杂处,应注意保持网垫平整,并要增加钉子的密度。 

4)注意搭接,搭接长度2cm,搭接处钉子应顺势钉入,钉子密度要增加一倍,搭接处上层网垫要靠紧,不留间隙。

5)钉子的形状,钉子上端宽度应大于网垫孔径2倍,以便同时同时起垂直镇-压作用。 

6)草籽播种深-度应根据土壤的商情,因地制宜而定,草种应选择适合当地气候条件,根系长,且发达的草种,有长根系的多年生小灌木间种更佳。  

7)草籽播种深-度应在网垫中,这样更能加强复合保护层的效用。 

8)草籽播种后,表土覆盖深-度应以盖住网垫为主,不要使网垫暴露在阳光下,以利延长使用年限。但注意有利于草籽的发芽和生长。 

9)草籽播种后,土层的含水量应以40-50为宜。并在土表层加压,以有利于草籽发芽。
