橡胶止水带施工与安装方法的正确性是使用橡胶止水带的关键所在，我们知道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。由于混凝土中有许多尖角的石子和锐利的钢筋，所以在止水带定位和混凝土浇捣过程中，应注意安装定位方法和浇捣压力，以避免止水带被刺破。由于塑料和橡胶的抗断撕裂强度比拉伸强度低3-5倍，所以如果产品被刺破将会大幅度降低产品抵抗外力的能力，故在施

The correctness of the construction and installation method of rubber water stop belt is the key to use rubber water stop belt. We know that rubber sealing strip is partially or wholly buried in concrete during pouring process. Because there are many sharp stones and sharp steel bars in the concrete, it is necessary to pay attention to installation positioning method and pouring pressure in the process of water stop positioning and concrete pouring and tamping, so as to avoid the sealing belt being punctured. Because the breaking tear strength of plastic and rubber is 3-5 times lower than that of tensile strength, if the product is punctured, it will greatly reduce the ability of the product to resist external force

工中要格外注意。

Pay special attention to the workers.

进行橡胶止水带施工时具体注意如下几个方面：当施工人员在绑扎钢筋和支模时，中埋式橡胶止水带必须采取可靠的固定措施，避免在浇注混凝土时发生位移，保证止水带在混凝土中的正确位置。对于固定橡胶止水带时，只能在止水带的允许部位上穿孔打洞，不得损坏本体部分。对于止水带的固定方法应按设计要求的施工规范进行，常用的固定方法有：利用附加钢筋固定；专用卡具固定；用铅丝和模板固定

The rubber waterstop construction when the specific attention to the following aspects: when the construction personnel in lashing reinforcement and formwork, buried rubber waterstop fixation must take reliable measures to avoid the occurrence of displacement, in the pouring of concrete, to ensure the correct position of waterstop in concrete. For the fixed rubber water stop, holes must be punched on the permitted part of the water stop belt, and the main part shall not be damaged. For the fixed method of waterstop shall be in accordance with the design requirements of the construction specifications, fixation methods are commonly used: the use of additional reinforcement fixation; special fixture fixation; fixation with wire and template

等。不论采用何种固定方法，都必须保证止水带定位准确，不损坏止水带有效部分，方便混凝土浇捣。

Etc.. No matter what kind of fixing method is adopted, it is necessary to ensure the accurate positioning of the water stop belt, not to damage the effective part of the water stop, and to facilitate the pouring and tamping of the concrete.

应尽量在工厂中连接成整体。如因制造工艺、运输条件等限制，需在现场连接的，应采用热压硫化胶合（橡胶止水带）或焊接（塑料止水带），其接头外观应平整光洁，抗拉强度不低于母材的80%。 不加任何处理的所谓“搭接”是**不允许的。橡胶止水带的各种交叉连结点，要使用我们成林公司生产成配件，以保证在施工中现场连接只在直线段进行。足够的变形能力，与混凝土具有良好粘接性能的柔性材料。

Should try to connect in the factory as a whole. As a result of the manufacturing process, transport conditions and other restrictions, in site connection, should use the hot glue (vulcanized rubber waterstop) or welding (plastic waterstop joints), its appearance should be smooth, the tensile strength of not less than 80% of the base material. The so-called "lapping" without any treatment is absolutely not allowed. The rubber sealing belt of various cross junction, to use our company into the forest production parts, to ensure the construction site in the connection only in a straight line segment. Sufficient deformation capacity for flexible materials with good adhesion to concrete.

在橡胶止水带施工过程中，由于混凝土中有许多尖角的石子和锐刃的钢筋，所以在浇捣和定位止水带时，应注意浇捣的冲击力，以免由于力量过大而刺破橡胶止水带。如发现有破裂现象应及时修补，否则在接缝变形和受水压时，橡胶止水带所能抵抗外力的能力就会大幅度降低。 在定位橡胶止水带时，一定要使其在界面部位保持平展，更不能让止水带翻滚、扭结如发现有扭转不展现象应及时进行调正。在浇铸固定止水带时，应防止水带偏移，以免单侧缩短，影响止水效果。在混凝土浇捣时还必须充分震荡，以免止水带和混凝土结合不良而影响止水效果。止水带接头必须粘接良好，如施工现场条件具备，可采用热硫化连接的方法 。

In the construction process of the rubber sealing belt, because there are many sharp stones and reinforced concrete in the sharp edge, so in the pouring and positioning of the waterstop, should pay attention to the impact of the cast, so as to avoid the excess force piercing the rubber sealing belt. If the rupture phenomenon is found, it should be repaired in time, otherwise, when the joint deformation and water pressure, the ability of rubber waterproof belt to resist external force will be greatly reduced. When locating the rubber stop belt, it is necessary to keep it flat at the interface, not to make the water stop roll and kink. If it is found that the torsion is not shown, the adjustment should be carried out in time. When casting the fixed water stop belt, the water belt deviation should be prevented, so as to avoid unilateral shortening and influence the sealing effect. The concrete must be fully shake when pouring and tamping, so as to avoid the bad combination of the water stop and the concrete and affect the sealing effect. The joint of the water stop belt must be well bonded, such as the condition of the construction site, and the method of heat vulcanization connection.
