伊犁遇水膨胀止水条规范
遇水膨胀止水条是以性能良好的膨润土为基础原料，通过物理和化学改性，使其具有较好的吸水膨胀性能和一般弹性体的弹性。依靠其自身的粘性直接粘贴预置在混凝土施工缝、后浇缝的界面上，二次浇注混凝土后（即被砼包裹的状态下）。是理想的环保的防水材料，已被国家众多大中型水利工程所采用。
The expansive water stop strip is a kind of bentonite based on good performance. It has excellent water swelling property and elasticity of general elastomer by physical and chemical modification. Relying on its own viscosity directly paste preset in the concrete construction joint, the interface of the pouring seam, after pouring concrete two times (that is wrapped by concrete). It is an ideal environmental protection waterproof material, which has been adopted by many large and medium-sized water conservancy projects in china.
遇到水后会逐渐膨胀,一方面堵塞可能存在的毛细孔隙、另一方面使其混凝土界面的接触更加紧密,从而产生较大的抗水压力，形成不透水的可塑性胶体，该止水产品具有膨胀倍率高，移动补充性强，置于施工缝，后浇缝后具有较强的平衡自愈功能，可自行封堵因沉降而出现的新的微小缝隙，对于已完工的工程，如缝隙渗漏水，可用该止水条重新堵漏，使用该止水条*且施工工艺简单，耐腐蚀性较佳。
When the water will gradually expand, on the one hand, there may be clogged pores on the other hand, the concrete interface contact more closely, resulting in high water pressure resistance, the formation of impermeable plastic sealing colloid, the product has high inflation rate, mobile added strong in construction joints, after pouring with the balance of self-healing function strong joints, self sealing for settlement and the emergence of a new small gap, has completed the project, such as the gap Water Leakage by the water infiltration, re plugging, using the seal of low cost and simple construction process, the best corrosion resistance.

遇水膨胀止水条安装施工方法:
Installation method of water expansion expansion strip:
1、在安装对有预留式的粘贴方式，在先浇混凝土中需预留上止水条安放槽（可在模板中钉木条预留）。拆除先浇混凝土模板后，清除表面，使缝面无水、干净、无杂物。
1, in the installation of reserved type of paste, prior to pouring concrete need to reserve a stop bar slot (can be nailed in the template reserved wood). After the concrete template is removed, the surface is removed, so that the joint surface is waterless, clean and without debris.
2、将止水条嵌入预留槽内。如不预留槽，对垂直缝可加用粘结剂全长粘贴，或用水泥钉加木条固定止水条；对水平缝可直接粘贴于混凝土表面。止水条粘贴以后应尽快浇注混凝土。在安装粘贴过程中，应防遇水膨胀止水条受污染和受水的作用膨胀，以免景响使用效果。
2. Insert the stop bar into the reserved tank. If the groove is not reserved, the vertical joint can be added with adhesive, the whole length is pasted, or the cement nail and the wood strip are used for fixing the water stop strip; the horizontal joint can be directly pasted on the concrete surface. The concrete should be poured as soon as possible after the stop bar is pasted. In the process of installation and sticking, the expansion strip should be prevented from being polluted and expanded by water, so as to avoid the effect of the use of the scene.
3、该产品预置于混凝土施工缝、后浇缝的界面上，二次浇筑混凝土后（即被混凝土包裹的状态下）遇水膨胀能彻底堵塞、阻隔渗漏水源。膨胀倍率高，移动补充性强。置于施工缝，后浇缝的该止水条具有较强的平衡自愈功能，可自行封堵因沉降而出现的新的微小裂隙。

3. The product is preset on the interface of the concrete construction joint and the post pouring joint. After two times pouring concrete (that is wrapped in concrete), the water expansion can completely block and obstruct the leakage water source. High expansion ratio, strong mobile supplement. The water stop strip, which is placed in the construction joint and the post pouring joint, has a strong balance self-healing function, and can automatically seal the new micro cracks due to settlement.
4、对于已完工的工程，如果缝隙渗漏水，可用该止水条重新堵漏。防水、抗渗效果优于传统的钢板、橡胶及塑料止水带，且施工方法简便易行，省工省时。主体材料为无机矿物原料，具有耐老化、抗腐蚀、无污染等特性。
4, for the completion of the project, if the gap leakage, the use of the water seal to re plugging. The waterproof and anti seepage effect is better than the traditional steel plate, rubber and plastic water stop belt, and the construction method is simple and convenient, saving labor and time. The main material is inorganic mineral material, which has the characteristics of aging resistance, corrosion resistance and no pollution.
