一、中置式橡胶止水带介绍
I. Introduction of central rubber water stop belt
中置式橡胶止水带也是就是通常所说的中埋式橡胶止水带，因为需要埋入混凝土中间，所以叫做中置式止水带，也叫做内埋式止水带，一般应用的为橡胶材质的，我公司还可以生产塑料中置式止水带。

Intermediate type rubber sealing strip is usually said in embedded rubber water stop belt, because of the need of embedded in concrete, it is called a built-in water stop, also called buried waterstop, the general application of the rubber material, our company can also produce plastic intermediate type water stop.

中置式止水带具有较好的防水功能。由于混凝土的施工缝的防水处理非常困难，特别是不均匀沉降或者是热胀冷缩的问题都非常难以彻底解决。因此采用止水带，特别是中置式橡胶止水带就会有非常好的效果。原理是通过橡胶的弹性，吸收不均匀沉降或者热胀冷缩带来的形变。
The central water stop belt has better waterproof function. The waterproof treatment of concrete construction joints is very difficult, especially the problem of uneven settlement or thermal expansion and cold contraction is very difficult to be completely solved. Therefore, the use of water stop belt, especially the rubber belt in the middle, will have very good effect. The principle is that the elasticity of rubber absorbs the uneven settlement or the deformation caused by thermal expansion and cold contraction.
二、中置式橡胶止水带分类及特点
Two. Classification and characteristics of central rubber water stop belt
中置式橡胶止水带当然一般是用作地下工程防水用的，止水带分为：止水带、遇水膨胀橡胶 1、止水带是利用橡胶的高弹性和压缩变形性，在各种荷载下产生弹性变形，从而起到紧固密封，有效地防止建筑构件的漏水、渗水，并起到减震缓冲作用，在许多工程建筑中，土建、水土结构之间都有一定的伸缩要求，并还有防水防震等问题，因此采用和安装橡胶止水带是有效解决以上种种问题的手段。主要用于混凝土现浇时必须设有的永久性变形缝内，如水渠、隧道引出口、挡水坝、输水渡槽等。 2、遇水膨胀橡胶是公司近期研制开发的一种新产品。本产品是在橡胶中加入一种亲水溶胀的高分子物质，使其既有一般橡胶制品的性能，又有遇水自行膨胀的独特性能，是一种新型防水材料，能起到以水止水的作用，防水效果比一般橡胶更为可靠。
Intermediate type rubber sealing belt of course is generally used in underground engineering waterproofing, sealing strip is divided into: waterstop, water swellable rubber sealing strip is 1, the use of rubber and high elastic compression deformation, elastic deformation under various loads, so as to effectively prevent the sealing, seepage, Water Leakage building components the play, and cushioning, in many engineering construction, there are certain requirements between the telescopic construction, soil structure, and there are problems such as waterproof and shockproof, so using and installing the rubber sealing strip is effective to solve the above problems by means of. It is mainly used for permanent deformation joints in concrete pouring, such as channel, tunnel outlet, dam, aqueduct and so on. 2, water swellable rubber is a new product developed by the company recently. This product is a polymer material with a hydrophilic swelling in the rubber, which not only has the general properties of rubber products, and has the unique properties of water self expansion, is a new type of waterproof material, can play a role in water sealing, waterproof effect is more reliable than the general rubber.
三、中置式橡胶止水带施工注意事项
Three, central rubber waterproof belt construction matters needing attention
中埋式橡胶止水带是在混凝土浇注过程中部分或全部浇埋在混凝土中。混凝土中有许多尖角的石子和锐利的钢筋头，由于塑料和橡胶撕裂强度比拉伸强度低3-5倍，中置式橡胶止水带一旦被刺破或撕裂时，不需很大外力裂口就会扩大，所以在中置式橡胶止水带定位和混凝土浇捣过程中，应注意定位方法和浇捣压力，以免中置式橡胶止水带被刺破，影响止水效果。
The embedded rubber water stop belt is partially or wholly buried in concrete during pouring process. There are many sharp stones and sharp head reinforced concrete, because the plastic and rubber tear strength than the tensile strength is 3-5 times lower, middle type rubber zhishuidai once punctured or torn, without a lot of external force will expand, so in the middle type rubber waterstop positioning and concrete pouring process, should pay attention to location method and pouring pressure, so as to avoid the intermediate type rubber sealing strip was punctured, affecting the sealing effect.
