1、雷诺护垫概述 护垫也叫石笼护垫、格宾护垫,是指由机编双绞合六边形金属网面构成的厚度远小于长度和宽度

  1、雷诺护垫概述
  护垫也叫石笼护垫、格宾护垫,是指由机编双绞合六边形金属网面构成的厚度远小于长度和宽度的垫形工程构件。雷诺护垫是厚 度在0.17-0.3m的网箱结构,其中装入块石等填充料后连接成一体,成为主要用于水利堤防、岸坡、海曼等的防冲刷结构,具有柔性、对地基适应性的优 点。
  2、雷诺护垫材质
 
  (1)镀锌钢丝:
  优质低碳钢丝,钢丝的直径2.0MM-4.0MM,钢丝的抗拉强度不少于380Mpa,钢丝的表面采用热镀锌保护,镀锌的保护层的厚度根据客户要求制作,镀锌量最大可达到300g/m2。
  (2)锌-5%铝-混合稀土合金钢丝:
  (也叫高尔凡)钢丝,这是一种近年来国际新兴的一种新材料,耐腐蚀性是传统纯镀锌的3倍以上,钢丝的直径可达1.0MM-3.0MM,钢丝的抗拉强度不少于1380Mpa。
  (3)镀锌钢丝包塑:
  优质低碳钢丝,在钢丝的表面包一层PVC保护层,再编织成各种规格的六角网。这层PVC保护层将会大大增加在高污染环境中的保护,并且通过不同颜色的选择,使其能和周围环境融合。
  (4)锌-5%铝-混合稀土合金钢丝包塑:在锌-5%铝-混合稀土合金钢丝的表面包一层PVC保护层,再编织成各种规格的六角网。这层PVC保护层将会大大增加在高污染环境中的保护,并且通过不同颜色的选择,使其能和周围环境融合。
  3、雷诺护垫参数
  (1)孔径:60*80mm、80*100mm、80*120mm、100*120mm、120*150mm其中双线绞合部分的长度不得小于50mm.以保证绞合部分钢丝的金属镀层和PVC镀层不受破坏
  (2)丝径:石笼网分三种丝径—网丝、边丝、绑丝
  A.网丝的范围在2mm-4mm
  B.边丝一般大于网丝,粗0.5mm-1mm
  C.绑丝一般小于网丝,常见的以2.2mm居多
  (3)钢丝拉力:不小于38kg/m2 380N/mm
  (4)表面处理
  A.电镀锌。上锌量最高为10g/m2,防腐性差
  B.热镀锌。上锌量最高可以达到300g/m2,防腐性较强
  C.高尔凡(锌铝合金)。这样的分为两种材质,锌-5%铝-混合稀土合金钢丝、锌-10%铝混合稀土合金钢丝,防腐性超强
  D.PVC包塑。包塑的厚度一般包1.0mm的厚度,例如:2.7mm包完后为3.7mm,防腐性强
  (5)隔断:在石笼网的长的方向上每一米加上一个隔断
  (6)尺寸:可定做
  (7)孔径、丝径所对照的范围
  4、雷诺护垫特点
  (1)提高河床边坡的稳定性
  (2)保护河床防止冲刷
  1, summary of Renault pads
  Pads also called stone cage pads, bing pads, it is to point to by machine weaving double twisted hexagonal wire netting the thickness of the surface composition is far less than the length and width of the cushion project artifacts. Renault pads are thick in the constructional 0.17 0.3 m, the loading block stone filling material such as connection into an organic whole, be mainly used for water scour prevention structure of embankment, bank slope, such as Hyman, possesses the advantages of flexibility, adaptability of foundation.
  2, Renault pads material
  (1) galvanized steel wire:
  High quality low carbon steel wire, steel wire of 2.0 MM to 4.0 MM in diameter, the tensile strength of steel wire shall not be less than 380 mpa, hot galvanizing protection on the surface of the steel wire, galvanized the thickness of the protective layer of production according to customer requirements, up to a maximum of 300 g/m2 galvanized quantity.
  (2) aluminum zinc - 5% - mixed rare earth alloy steel wire:
  (also called al gore who) wire, this is a kind of international emerging in recent years, a kind of new materials, corrosion resistance is three times bigger than the traditional pure galvanized, steel wire diameter of 1.0 MM to 3.0 MM, the tensile strength of steel not less than 1380 mpa.
  (3) the plastic coated galvanized steel wire:
  High quality low carbon steel wire, PVC protective layer on the surface of steel wire package, and then woven into various specifications hexagonal wire netting. This layer of PVC protective layer will increase significantly in the high pollution in the environment protection, and through the choice of different color, can make the fusion and the surrounding environment.
  (4) aluminum zinc - 5% - mixed rare earth alloy wire package: aluminium zinc - 5% - mixed rare earth alloy wire a layer of PVC coating the surface of the bag, and then woven into various specifications hexagonal wire netting. This layer of PVC protective layer will increase significantly in the high pollution in the environment protection, and through the choice of different color, can make the fusion and the surrounding environment.
  3 and the parameters of the Renault pads
  (1) the aperture: 60, 80 * 100 mm, 100 * 80 mm * 120 mm, 100 * 120 mm, 120 * 150 mm including double stranded part shall not be less than 50 mm. The length of the part to ensure the stranded wire metal coating and PVC coating are not destroyed
  (2) size: stone cage mesh points and three kinds of wire diameter, mesh, wire, tie wire
  A. the scope of the mesh in the 2 mm to 4 mm
  B. the side wire generally greater than net wire, thick 0.5 mm - 1 mm
  C. tie silk generally smaller than the mesh, common in the majority with 2.2 mm
  (3) the wire tension: not less than 38 kg/m2 380 n/mm
  (4) surface treatment
  A. electric galvanized. On a maximum of 10 g/m2, zinc amount anticorrosion sex differences
  B. hot dip galvanized. Zinc amount up to 300 g/m2, strong corrosion
  C. gore (zinc alloy)。 This is divided into two kinds of material, aluminum zinc - 5% - mixed rare earth alloy steel wire, aluminum zinc - 10% mixed rare earth alloy wire, anticorrosion strong
  D.P VC plastic coated. The thickness of the plastic coated the thickness of 1.0 mm general package, for example: 2.7 mm after the package is 3.7 mm, anti-corrosion
  (5) : partition on the stone cage net long direction every meter plus a partition
  (6) size: can be customized
  (7) the aperture, the range of wire diameter control
  4, Renault pads, etc
  (1) to enhance the stability of river bed slope
  (2) protect the river to prevent scour?
  (3) to provide the bank book value of roughness coefficient (m)
  (4), slope protection, bank protection afforestation and ecological protection
  (5) the construction is convenient
