遇水膨胀止水条50*50mm

遇水膨胀止水条膨胀率高且膨胀后整体性好，平衡自愈功能好、移动补充性强、可自行封堵微小裂缝，阻隔渗漏水源实现主动止水和 止水的作用，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。下面主要介绍一下遇水膨胀止水条安装施工方法。

Water swelling rate is high and the expansion of the overall good water swelling, good self-healing function, balance ability, self moving of blocking tiny cracks, leakage of water and water barrier to realize active permanent sealing effect, is the ideal environmental protection waterproof material, has been used in many large and medium-sized water conservancy projects. The following main introduction of the water expansion of the water expansion bar installation method.

遇水膨胀止水条安装施工方法：

Construction method for installation of water expandable water stop bar:

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 a reserved type of sticker, in the first cast concrete needs to be reserved on the water stop slot (can be retained in the template in advance). After dismantling the formwork of the first cast concrete, the surface was cleared and the seam surface was water, clean and no sundries.

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, the water stop bar is embedded in the reserved slot. If no slot is reserved, the vertical joint can be cemented with full length paste, or fixed with cement pin and wood bar, and the horizontal seam can be directly pasted on the concrete surface. The concrete should be poured as soon as the sealing strip is pasted. During the installation and stickup process, the water expansion seal should be prevented from being polluted and inflated by the action of water, so as to avoid the effect of the scene.

3、遇水膨胀止水条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, water expansion and water stop bars are placed on the interface of concrete construction joints and post poured joints. After two times pouring concrete, the water expansion can completely block up and obstruct the source of water leakage. The expansion ratio is high and the mobility is strong. In the construction seam, the post - pouring seam has a strong balance self - healing function, and can block the new small fissure, which is caused by the 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 completed project, if the crevice seepage water, can be used to stop the leakage of the water. 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 easy to save time and labor. The main material is inorganic mineral material, which has the characteristics of aging resistance, corrosion resistance, pollution free and so on.
