可卸式橡胶止水带施工安装方法
Construction and installation method of removable rubber water stop belt

为了便于安装可卸式止水带，需提前安装预埋螺栓，要提前将预埋螺栓固定在提前预埋好的加钢板止水片的钢板上，并浇筑预埋在混凝土内部，该部分混凝土要仔细振捣确保其密实度；变形缝的转角部位应做成圆弧形或45°角，圆弧半径应根据预埋螺栓的长度确定，以2个相邻螺栓头的距离不影响止水带和止水带夹板安装为准；预埋螺栓时为了防止其被腐蚀应在螺栓上涂抹黄油或加PVC套管；止水带的固定应根据现场螺栓实际位置采用皮带冲打孔方法，在止水带安装过程中不能用力拉扯止水带，止水带与夹板间以及与预埋钢板之间应填加石棉纸或软金属片衬垫以确保严密性。

In order to facilitate the installation of the detachable sealing strip, pre buried bolt installed in advance, to advance to the waterstop and plate pre buried bolt fixed in advance of embedded steel plate, and embedded in the concrete pouring, the concrete should be carefully vibrated to ensure the compactness of the corner joints; deformation should be made the circular arc or angle of 45 degrees, arc radius should be determined according to the pre buried bolt length, bolt head to 2 adjacent distance does not affect the sealing strip and sealing belt splint installation; embedded bolts in order to prevent them from corrosion in butter or bolts with PVC sleeve tube; waterstop shall according to the actual position of the bolt punched belt method in the waterstop process can not pull the waterstop, between the waterstop and splint and embedded steel plate should be filled with asbestos paper or soft sheet metal gaskets to ensure Tightness.
止水带是一种专用于建筑工程施工缝及变形缝的防水密封材料。
Waterproof belt is a kind of waterproof and sealing material which is specially used for construction joints and deformation joints of construction projects.
一、 止水带作用：止水带是利用橡胶的高弹性，在各种压力荷载下产生弹性变形,从而起到坚固密封,可以有效地防止建筑构造的漏水,渗水并起到减震缓冲作用。
First, the role of water stop: water stop belt is the use of high elasticity of rubber, elastic deformation under various pressure loads, so as to play a strong seal, can effectively prevent the leakage of building structure, seepage, and play a role in damping buffer.
二、 止水带用在什么工程中？
Two. What are the water stopping strips used in?
在一般较大工程的建筑设计中，由于不能连续浇筑，或由于地基的变形，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，在这些缝外必须安装止水带来防止水的渗漏问题。这些缝的防渗漏问题就要采用在变形缝的部位浇铸橡胶止水带的办法来解决，它即能防止地下水(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。
In the architectural design of general larger projects, due to the continuous casting, or as a result of the ground deformation, or concrete caused by thermal expansion due to temperature change and contraction, to save construction joints and settlement joints, distortion seam, seam must be installed in the water brought to prevent water leakage problems. The anti leakage seam problems must be used in the deformation of the parts casting with rubber sealing way to solve, it can prevent the leakage of groundwater (or outside water) to the building structure, and can prevent water leakage to outside buildings.
止水带广泛用于各种类型的混凝土结构中。例如：挡水坝、蓄水池、地铁、涵洞遂道等地下工程中。
The water stop strip is widely used in various types of concrete structures. For example: dam, reservoir, subway, culvert tunnel and underground engineering.
三、止水带的设计与选用
Three. Design and selection of water stop belt
止水带的选择：应根据构筑物的重要性等级，变形缝变形量及水压，止水带的适用工作环境，经济因素等条件综合考虑确定。
The selection of water stop belt should be determined according to the importance grade of the structure, the deformation amount and water pressure of the deformation joint, the applicable working environment of the water stop belt, and the economic factors, etc..
止水带材质的选择可按下列规定：
The choice of the material for the water stop belt can be made according to the following regulations:
1、一般情况下多选用天然橡胶止水带
1. In general, natural rubber waterproof belt is usually used
2、当遇有弱酸酸、碱类腐蚀介质时，宜选用氯丁橡胶止水带
2, when there is weak acid and alkali corrosion medium, it is better to use neoprene waterproof belt
3、当遇有油类介质时宜选用丁腈橡胶止水带
3, in case of oil medium should choose nitrile rubber waterproof belt
4、当遇有霉菌侵蚀的可能时，应考虑橡胶止水带的防霉性，其等级应达到2级2级以上。
4, when there is the possibility of mold erosion, should consider the rubber waterproof tape mildew resistance, its grade should reach 2, 2 or more.
5、当使用温度为：-25-60摄氏度时选用氯丁橡胶止水带，-35-60摄氏度时选用天然橡胶止水带，-40-60摄氏度时选用三元乙丙橡胶止水带
