橡胶止水带
rubber waterstop
止水带是利用橡胶高弹性和压缩变形性的特点，在各种载荷下产生弹性变形，从而起到有效紧固密封，防止建筑漏水、渗水及减震缓冲作用。在一般较大工程的建筑设计中，由于不能连续浇注。可由于地基的变形，或由于温度变化引起的混凝土构件热胀冷缩等原因，需留有施工缝、沉降缝、变形缝，在这些缝处必须安装止水带来防止水的渗漏问题。
The water stop belt is characterized by high elasticity and compression deformation of rubber, and produces elastic deformation under various loads, thus effectively fastening and sealing, preventing building leakage, water seepage and shock absorption buffering effect. In general architectural design of large projects, it can not be continuously poured. Because of the deformation of foundation or the expansion and contraction of concrete component caused by temperature change, the construction joint, settlement joint and deformation joint should be left, and the water stop must be installed at these joints to prevent water leakage.
橡胶止水带是采用天然橡胶与各种合成橡胶为主要原料，掺加各种助剂及填充料，经塑炼，混炼， 压制成型，其品种规格较多，有桥型、山型、P型、R型、U型、Z型、乙型、T型、H型、E型、Q型等。该止水材料具有良好的弹性，耐磨性、耐老化性和抗撕裂性能，适应变形能力强、防水性能好，温度使用范围-45℃-+60℃。当温度超过+70℃，以及强烈的氧化作用或受油类等有机溶剂侵蚀时，均不得使用该产品。
The rubber sealing strip is made of natural rubber and various synthetic rubber as the main raw material, and the filling material mixed with various additives, through mixing, mixing, molding, the more varieties of different specifications, bridge, mountain type, P type, R type, U type, Z type, T type, H type, type, E type and Q type etc.. The sealing material has good elasticity, wear resistance, aging resistance and tear resistance. It has good deformation ability and good waterproof performance. Its temperature range is -45 degrees centigrade and -+60 degrees centigrade. This product should not be used when the temperature is higher than +70 degrees, and it is strongly oxidized or eroded by organic solvents such as oil.
止水带主要用于混凝土现浇时设在施工缝及弯形缝内与混凝土结构成为一体的基础工程，适用于受振动、易变形、荷载较大的建筑物及构筑物的接缝止水处理如：地铁、道路、隧道、桥梁、伸缩缝、沉降缝、拦水坝、地下设施、隧道漏洞、输水渡槽、高低跨建筑物、贮液构筑物等。
The waterstop is mainly used for foundation engineering of cast-in-place concrete in construction joints and when bending joints and concrete structure as a whole, suitable for vibration, easy deformation, large load of buildings and structures in the joint seal processing such as: subway, roads, tunnels, bridges, expansion joints and settlement joints, dams, underground facilities tunnel, leak, aqueduct and low cross building, liquid storage structures etc..

中埋式止水带：
Embedded type water stop belt:
中埋式止水带是利用橡胶的高弹性和压缩变形性的特点，在各种载荷下产生弹性变形，从而起到有效紧固密封，防止建筑结构的漏水、渗水及减震缓冲作用。在许多工程建筑设计中，土建、水土结构之间都有一定的伸缩要求，并存在防水防震等问题，因此采用和安装橡胶止水带是有效地解决以上种种问题的手段。本产品主要用于混凝土现浇时设在施工缝及变形缝内，与混凝土结构成为一体的基础工程、地下设施、隧道涵洞、输水渡槽、挡水坝等，确保工程建设的使用寿命。
Because of the characteristics of high elasticity and compression deformation of the rubber, the embedded water stop belt produces elastic deformation under various loads, so as to effectively seal and prevent the leakage, seepage and shock absorption of the building structure. In many engineering building design, there are certain expansion requirements between civil engineering, water and soil structure, and there are waterproof, shockproof and other issues, so the use and installation of rubber water stop is an effective means to solve the above problems. This product is mainly used for concrete pouring in the construction joints and deformation joints, and the concrete structure as one of the basic works, underground facilities, tunnel culverts, aqueduct aqueduct, dam, etc., to ensure the construction of the service life.
中埋式止水带采用国家标准GB18173.2-2000《高分子防水材料止水带》组织生产的。 因此我们可以按用户要求生产各种形状、尺寸的橡胶止水带，另外还为不同工程、不同部位的需要备有十字型，丁字型、斜度型和内外转角型产品，可适用于任何设计要求。
The embedded water stop belt is produced and manufactured by national standard GB18173.2-2000 "polymer waterproof material stop belt". Therefore, we can produce rubber sealing strips of various shapes and sizes according to the requirements of users. Besides, the products of cross type, T-shaped type, slope type and inner and outer corner type products are available for different engineering and different parts, which can be applied to any design requirements.
中埋式止水带广泛应用于各种类型的混凝土结构中。例如：挡水坝、蓄水池、地铁、涵洞、隧道等地下工程中，由于不能连续浇注，或由于地基的变形，或由于温度变化引起混凝土构件的热胀冷缩等原因，在浇注时常留有变形缝、施工缝，这些缝的防渗漏问题就要采用在变形缝的部位浇注橡胶止水带的办法来解决，它既能防止地下水（或外界水）渗漏到建筑结构中，又可防止建筑内的水漏到外界。
The embedded water stop belt is widely used in various types of concrete structures. For example: dam, reservoir, subway, culverts, tunnels and other underground projects, due to the continuous casting, or as a result of the ground deformation due to temperature changes, or the cause of concrete expansion and contraction, often left in the casting deformation joints, construction joints, these joints leakage problems must be used in the deformation zone the way of joint parts casting rubber seal to solve, it can prevent the leakage of groundwater (or outside water) to the building structure, and can prevent water leakage to outside buildings.
橡胶止水带在运输时，应要避免阳光直射，勿与热源、油类及有害溶剂接触。成品应取直平放，勿加重压。存放场所保持-10-+30，相对湿度40%-80%。
The rubber sealing belt during transportation, should avoid direct sunlight, do not contact with heat, oil and harmful solvent. The finished product should be straight and flat, without heavy pressure. Storage place is best to maintain -10-+30, relative humidity 40%-80%.
