膨胀橡胶止水带 防洪堤坝密封止水带
Sealed water sealing belt for flood control dyke of swelling rubber belt
遇水膨胀橡胶止水带并不是指止水带本身膨胀，而是一种在普通中埋式橡胶止水带的基础上增加膨胀防水线的一种止水带类型。
The water expansion rubber water stop does not mean the expansion of the water stop itself, but a kind of waterstop belt which is added to the expansion waterproof line on the basis of the ordinary embedded rubber water stop.
膨胀的部分是膨胀线。橡胶部分与橡胶止水带物理机械性能相同，执行GB18173.2-2000标准，它又被称为“橡胶膨胀止水带”。
The expansion part is the expansion line. The rubber part and the rubber water stop belt have the same physical and mechanical properties, and carry out the GB18173.2-2000 standard. It is also called the "rubber expansion water stop belt".
膨胀线胶料执行标准GB/T18173.3-2002，除具有橡胶止水带的性能外，其主要特点是内防水线采用了具有遇水膨胀特性的橡胶来制成。
The standard for expansion line is GB/T18173.3-2002. Besides the performance of rubber water stop, its main feature is that the internal waterline is made of rubber with water expansion characteristics.
止水带在膨胀橡胶作用下遇水开始膨胀并且增强了止水带和构筑物的紧密度,使防水、止水效果更好。
The water stop zone begins to expand under the action of swelling rubber and strengthens the tightness of the water stop belt and structure, so that the effect of water proof and water stop is better.
橡胶膨胀止水带的性能特点橡胶止水带遇到水后，体积就会膨胀，因此本产品可以广泛应用于各种类型的混凝土结构中，
The performance of the rubber expansion and sealing belt will expand if the rubber sealing belt meets water, so this product can be widely applied to all kinds of concrete structures.
例如：挡水坝、蓄水池、地铁、涵洞、隧道等地下工程中。在这些工程中，由于不能连续浇铸，或由于地基的变形，或由于温度变化引起的混凝土构件的热胀冷缩等原因，在浇铸时常留有变形缝、施工缝，这些缝的防渗漏问题就要采用在变形缝的部位采用橡胶膨胀止水带的方法来解决，它既能防止地下水或外界水渗漏到建筑物结构中，又可防止建筑内的水漏到外界.
For example, the dam, the reservoir, the subway, the culvert, the tunnel and other underground works. In these projects, due to the continuous casting, or as a result of the ground deformation, or caused by temperature change of concrete thermal expansion and contraction, often left in the casting deformation joints, construction joints, these joints leakage problems must be used in the deformation of the rubber parts production expansion waterstop to to solve it, which can prevent water leakage of groundwater or external to the building structure, and can prevent the leakage of the building to the outside world.
