1.背贴式橡胶止水带的应用范围
Application range of 1. back mounted rubber water stop belt
外贴（背贴）型橡胶止水带作为防水板的辅材，可广泛应用于地下室、地铁隧道、公路和铁路隧道工程的防水及水坝、人工湖、水池、污水处理场、垃圾掩埋场等工程的混凝土构筑物底板或壁板外侧（构筑物迎水面）的防水及防渗。
Stick (back) type rubber waterstop waterproof board as auxiliary materials, can be widely used in the basement, metro tunnel, highway and railway tunnel waterproofing and dams, artificial lakes, ponds, sewage treatment plant, landfill and other engineering concrete structures (lateral bottom or wall structures upstream) waterproof and **-seepage.
2.施工生产的的原理：
2. the principle of construction and production:
实际应用中主要使用在水压及变形量较小的变形缝、伸缩缝、沉降缝等，具有与混凝土锚固紧密、止水密封及适应伸缩缝拉伸变形等特点，结构物的背贴式止水带也可作为普通止水带使用，应用于混凝土现浇时变形缝、施工缝内与混凝土结构成为一体的基础工程中，解决缝隙处的渗漏水问题背贴式止水带主要适用于混凝土构筑物底板或壁板外侧（混凝土迎水面）。具有与混凝土锚固紧密、止水密封及弹性拉伸变形等特点。外贴式止水带是防水板后的**道防水层，对于隧道渗水的预防至关重要。
The practical application is mainly used in deformation pressure and smaller deformation joints, expansion joints and settlement joints, with close, anchorage and concrete seal and adapt to the characteristics of expansion joints tensile deformation, the structure of back stick type waterstop also can be used as ordinary waterstop, applied to cast-in-place concrete deformation seam, the construction joints and concrete structure has become one of the basic engineering, to solve the problem of water leakage of the gaps of back stick type waterstop is mainly applicable to concrete structures (concrete bottom or wall outside the surface). It has the characteristics of close anchoring with concrete, water sealing and elastic tensile deformation. The external waterproof belt is the first waterproof layer after the waterproof board, which is very important for the prevention of the tunnel seepage.
3.具体的施工方法：
3. specific construction methods:
方法1、在止水带背面配30mm厚木模板，模板的宽度和长度应满足止水带安装的要求，木模板应与外墙整体模板连成一体，以防浇筑混凝土时木模板发生位移、漏浆，失去止水作用。同时用212in（lin=25mm）双帽钉将外贴式橡胶止水带与木模板固定，将双帽钉钉在止水带两侧最边缘部位，每隔200mm钉双帽钉一个。安装好的止水带应平整，无下垂现象，此部位在浇筑混凝土后，强度达到设计强度的80%以上方可拆模。
1, in the back of the waterstop with 30mm thick template, the width and length of the template should meet the requirements of the waterstop, wood template should integrated with external entity template, in case of pouring concrete formwork displacement, slurry leakage, loss of sealing effect. At the same time, 212in (lin=25mm) double cap nail is used to fix the outer rubber sealing strip and wood template, and the double cap nail is nailed to the most edge part of the water stop belt, and every 200mm nail double cap nail. With good water installation should be smooth, no sagging phenomenon, this part after the pouring of concrete, strength to meet the design strength of 80% to the top of demolding.
方法2、在止水带背面砌筑2400mm厚砖墙作为外模，砖墙的宽度和长度应满足止水带安装的要求，砖墙应与外墙整体模板（钢模、竹模等）连接成一体，以免浇筑时漏浆，失去止水作用。砖墙内侧提前粘贴3mm厚的三元乙丙橡胶防水卷材或氯丁橡胶片（粘贴于砖墙内侧抹灰层之上，要牢固）然后再将橡胶止水带与其用401防水胶粘贴牢固。
2, in the back of the waterstop laying 2400mm thick brick wall brick as external mold, the width and length of the waterstop shall meet the installation requirements, and the exterior brick walls should be overall template (steel, bamboo formwork etc.) connected together, so as not to lose the sealing effect when casting the slurry. In the interior of the brick wall, 3mm thick EPDM rubber waterproofing membrane or chloroprene rubber sheet (adhered to the inner plastering layer of the brick wall) should be affixed in advance, and then the rubber water stop belt will be bonded firmly with 401 waterproof glue on it, and then it will be firmly bonded with the three waterproof glue.
