排水隧洞橡胶止水带
一、产品用途详细介绍：中埋式止水带主要用于在混凝土变形缝、伸缩缝等混凝土内部设置的止水带产品，具有以橡胶材料弹性和结构形式来适应混凝土伸缩变形的能力。主要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，可确保工程建筑物的使用寿命。
A detailed introduction, product use: mainly used in buried waterstop joints, expansion joint seal of concrete internal settings with product deformation in concrete, has the ability to adapt to concrete deformation with elastic rubber material and structure. The main use of rubber, high elasticity and compression deformation, elastic deformation under various loads, so as to effectively prevent the sealing of building components Water Leakage, seepage, and play a cushioning, can ensure the service life of the building project.
二、特别说明：中埋式止水带中间的圆孔在安装止水带时一般都在建筑体的沉降缝处，而沉降缝的接口处是建筑体在发生沉降时产生“形变”距离的地方；由此看来，如果止水带是“平的单层面”的，那同样材料的橡胶的“抗形变沿伸性”就没有横断面为圆形的好（因为圆的还带有弧度可沿伸的由“半圆变为直径”的一段长度差别）；还有，圆形的横断面在沉降缝的断面上为双层，比“平板”的多了一层，可以起到防止“层损坏”后仍能保持止水的作用。
Two, note: medium buried waterstop in the middle of the hole installed waterstop is generally in the construction of the settlement joint, and the settlement is building the seam "deformation" distance in the event of settlement therefore, if the sealing strip is "single" flat. The same material of rubber anti deformation along the stretch of "no good round sections because the circle with radian can be from" extending along the length to diameter difference between the semicircle " also, the circular cross-sectional in the section of the settlement joint is double, than" flat "a layer, you can play against the" first layer damage "can still maintain the effect.
三、用途及适应温度：
Three, use and adaptive temperature:
普通型：－25℃－+60℃；
Common type: +60 - 25 DEG C c
耐寒型：－40℃－+60℃
Hardy: 40 DEG C +60
四、本产品接头方法有两种：一种是采用粘接剂进行冷接头，一种是使用热硫化模具进行热接。
Four, this product joint method has two kinds: one is the use of adhesive for cold joint, one is the use of heat curing die for thermal connection.
1、冷接法：采用橡胶止水带冷接胶水、采用搭接法把止水带需要接头的断面用磨光机磨平5~10厘米、涂胶水压实即可，具有强度高、凝固快的优点、施工方便、省时省力，可达到一般工程质量要求。
1, cold joint: the rubber sealing strip special cold joint glue, overlapped by the waterstop joints with grinder grinding section to 5~10 cm, glue can be compacted, has high strength, fast solidification has the advantages of convenient, time-saving, can meet the general engineering quality requirements.
2、热接硫化法：使用与止水带匹配的热硫化模具及生胶片现场硫化热接，施工难度大，但接头效果理想，适合对工程质量要求严格的项目。
2, heat vulcanization method: using the heat curing mold matched with the water stop belt and the raw film on-site vulcanizing thermal connection, the construction is difficult, but the joint effect is ideal, suitable for the strict requirements of the project quality.
