背贴式止水带图片///

中埋式止水带按照外观形式可分为CB型（埋入式中间有孔）橡胶止水带和CP型（埋入式中间无孔）橡胶止水带，在实际应用中以CB型橡胶止水带应用最为广泛。
The middle buried waterstop belt can be divided into CB type (buried middle hole) rubber water stop belt and CP type (embedded intermediate non hole) rubber sealing belt according to the appearance. In the practical application, the CB type rubber water stop is the most widely applied.
按照加工形式又可分为651型橡胶止水带，钢边橡胶止水带，遇水膨胀止水带，钢板腻子止水带。其中651橡胶止水带最为常用。

According to the processing form, it can be divided into 651 types of rubber sealing belt, steel edge rubber sealing belt, water swelling stop belt and steel plate putty. 651 of the rubber belts are most commonly used.
中埋式止水带顾名思义就是埋入混凝土内的，利用橡胶自身的高伸长率和高抗拉强度，来实行对混凝土伸缩缝的密封防水。
The buried watertight belt, as the name implies, is embedded in the concrete, and the high strength and high tensile strength of the rubber itself is applied to carry out the sealing and waterproofing for the expansion joint of the concrete.
其中CB橡胶止水带主要应用于沉降缝，伸缩缝。而CP型止水带应用于施工缝。
The CB rubber sealing belt is mainly used for settlement joint and expansion joint. The CP type water stop belt is applied to the construction seam.
CB橡胶止水带中以651止水带用途最广，651止水带外观为两边为燕尾式设计，中间为圆孔式，圆孔两侧分别有三道防水张突起。
In the CB rubber water stop, the 651 waterstop is the most widely used. The 651 waterstop is designed with both sides on the swallow tail. The middle is circular hole type, and there are three watertight protrusions on both sides of the circular hole.
规格有200mm,250mm，280mm，300mm,350mm,400mm,450mm,500mm宽度的，
Specifications have 200mm, 250mm, 280mm, 300mm, 350mm, 400mm, 450mm, 500mm width,
厚度为6mm-25mm之间，
The thickness is between 6mm-25mm,
中心孔的外直径一般为20mm，25mm,30mm,40mm和50mm.当然也可根据客户需求定制加工。
The outer diameter of the center hole is generally 20mm, 25mm, 30mm, 40mm and 50mm., of course, can also be customized according to customer needs.
背贴式止水带按材质可分为外贴橡胶止水带和外贴塑料止水带，按施工位置可分为EP中间无孔型外贴止水带和EB中间有孔型外贴止水带。
The back sticking type waterstop belt can be divided into outer rubber water stop belt and outer plastic water stop belt according to material quality. According to the construction position, it can be divided into EP middle non porous external sealing water stop and EB middle hole type external water stop belt.
在隧道施工中以橡胶材质为主，但这一行业经过近几年的发展， 开发出了塑料外贴止水带，其优势在于采用与同一工程部位采用的防水板为同一材质，因为这样可使得防水板与止水带焊接为一体，
based on the rubber material in the tunnel construction, but the industry after years of development, has developed a plastic stick water stop, the advantages of waterproof plate used with the same project site for the same material, because it can make the waterproof plate and strip welded together,

保证了在防水板吊装和止水带安装中便捷与牢固，同时防水效果也大大加强。水利工程防水上还是以橡胶材质为主。因为橡胶具有较好的利用高弹性，在各种荷载下产生弹性变形，从而起到坚固密封，有效地防止建筑构造的漏水，渗水并起到减震缓冲作用。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
It is ensured that it is convenient and firm in the installation of the waterproof board and the installation of the water stop belt, and the waterproof effect is also greatly strengthened. The waterproofing of water conservancy works mainly with rubber material. Because rubber has good elasticity and elastic deformation under various loads, so that it can play a solid seal. It can effectively prevent the leakage of building structure, seepage and play a cushioning effect. In many engineering building designs, there are certain requirements for expansion and contraction between civil structures and water and soil structures, and there are problems such as water and shock proof. Therefore, the installation and installation of rubber water stop is an effective way to solve these problems. This product is mainly used for concrete cast-in-place engineering, underground facilities, tunnel culverts, water conveyance aqueducts, water retaining dams, etc., which are integrated into concrete construction in the construction joints and deformation joints, so as to ensure the service life of the project.
