Sewerage rubber belt
产 品 说 明
Product description
该止水带属隧道与地下工程混凝土衬砌三缝(施工缝、伸缩缝和沉降缝)内置式止水带。它由绕道、翼缘、膨胀橡胶条和止浆滤水带组成(如图)。其特点：一是在止水带内提供了一条下部与隧道排水系统相通的排水通道，使止水带外侧无渗水压力；二是在三缝两侧的止水带翼缘上粘贴有遇水膨胀橡胶条，用以阻止渗水沿止水带横向流动。该止水带适用于隧道与地下工程衬砌三缝的防水。
The water stop belt is a built-in water stop belt for three joints (construction joints, expansion joints and settlement joints) of concrete lining in tunnel and underground engineering. It consists of a detour, a flange, an expanded rubber strip, and a slurry filter (Figure). The utility model is characterized in that the sealing belt provides a drainage passage communicated with the lower tunnel drainage system, the water stop outside without seepage pressure; two is in the water three on both sides of the joint with flange are pasted on the water swellable rubber, to prevent water seepage along the lateral flow of water stop. The water stop belt is suitable for waterproofing of three seam lining of tunnel and underground engineering.

Product description
1. 止水带应用范围：
1. application range of water stop belt:
本产品广泛应用于各种类型的混凝土及现浇混凝土结构中。例如：暗渠、挡水坝、蓄水池、倒虹吸、地铁、涵洞、隧道、水电站、热电厂等。在这些工程中有时不能连续浇筑，或由于地基变形及温度变化等原因会引起混凝土构件的热胀冷缩，因此在浇筑时要留有变形缝、施工缝。这些缝的防渗、防漏问题可以通过采用橡胶止水带的办法来解决。它既能防止地下水（或外界水）渗漏到建筑结构中，又可以防止建筑内的水漏到外界，使用效果良好。
This product is widely used in various types of concrete and cast-in-place concrete structures. For example, culverts, dams, reservoirs, inverted siphon, subway, tunnel, culvert, hydropower, thermal power plant etc.. In these projects, sometimes it can't be continuously poured, or because of the deformation and temperature changes of the foundation, it will cause the expansion and contraction of the concrete members. Therefore, there are deformation joints and construction joints when pouring. The seepage prevention and leakage prevention of these joints can be solved by adopting the method of rubber sealing belt. It can prevent the leakage of groundwater (or outside water) to the building structure, and can prevent water leakage within the building to the outside world, the use effect is good.
2. 止水带的设计与选用：
2. design and selection of water stop belt:
1.1止水带的选择
Selection of 1.1 water stop belt
应根据构筑物的重要性等级、变形缝变形量及水压、止水带的使（应）用工作环境、经济因素等条件综合考虑确定。
It should be determined according to the importance rank of structure, the amount of deformation and deformation of the deformation joint, and the conditions of water pressure and water stop.
