可应用在任何地面或地下建筑，形成一道长久而坚固的隔水屏障，特别适用于储水和挡水的结构，例如水库、污水池、水坝、地铁、隧道挡水墙等.
the utility model can be applied to any ground or underground building, forming a long and strong barrier for water storage, especially for the structure of water storage and water retaining, such as reservoirs, sewage pools, dams, subways, tunnel retaining walls, etc.
防水板采用空铺法固定在喷射混凝土的基面上，防水板与后浇混凝土之间无法密贴。而防水板铺设时很容易出现破损部位，一旦破损部位未发现并且进行修补，就会造成渗漏水进入防水板和二衬结构之间．在结构不密实或开裂部位渗出。产生窜水现象，给后期堵漏维修工作带来很大困难．这就是防水板全包防水层的缺陷。为解决这一难题，就需要在防水层表面设置分区注浆系统。
the waterproof board is fixed on the base surface of the shotcrete by the empty paving method, and the waterproof board and the post pouring concrete can not be densely pasted. the waterproof board laying easily damaged parts, once damaged parts were found and repaired, it will cause water leakage into the waterproof board and two lining structure. in the structure is dense or cracking site exudation. the phenomenon of water channeling brings great difficulties to the later plugging and maintenance work, which is the defect of the waterproof layer of the waterproof board. in order to solve this problem, it is necessary to set the district grouting system on the surface of waterproof layer.
分区系统是通过一定的手段，将防水区域分隔开，这样如果个别区域内一旦出现渗漏，渗漏水不会窜入其它防水区域内，减少后期的注浆堵漏工作量。这样的分区系统就靠背贴止水带来实现。背贴式止水带是防水板后的第一道防水层．对于隧道渗水的预防至关重要。为保证后灌注的混凝土与止水带之间咬合密实．减少出现窜水的现象，需要在背贴式止水带两侧的齿条间设置注浆花管，一旦出现不实现象可以通过注浆花管进行注浆。

the partition system is to separate the waterproof area through some means, so if there is leakage in the inpidual area, the leakage will not be channeling into other waterproof areas, so as to reduce the late grouting plugging work. this partition system enables the backrest to be watertight. the back waterproof belt is the first waterproof layer after the waterproof board, which is very important for the prevention of the tunnel seepage. in order to ensure the concrete and water perfusion zone between the occlusal density. to reduce the water channeling phenomenon, need to set the rack mounted in the sealing grouting back belt on both sides of the flower tube, once the false phenomenon by grouting pipe grouting.

eva塑料止水带它由pvc聚氯乙烯树脂及各种填加剂，经混合、造粒、挤出等工序而制成的止水材料。此产品利用弹性体材料具有的弹性变形特性在建筑构造接缝中起到防漏、防渗作用，并且具有耐腐蚀、耐久性好的特点。
eva plastic water stop belt is made of pvc polyvinyl chloride resin and various filling agent. it is made up of mixing, granulating and extruding process. this product uses elastic deformation characteristics of elastomer material to play a role of leak prevention and seepage prevention in building structural joints, and has the characteristics of corrosion resistance and durability.
eva塑料止水带主要用于混凝土浇注时设置在施工缝及变形缝内与混凝土构成为一体的基础工程。如隧道、涵洞、引水渡槽、拦水坝、贮液构筑物、地下设施等。pvc塑料止水带施工方法与普通的橡胶止水带相同。在浇埋时要使其与混凝土界面贴合平整，接头部分粘接紧固，浇埋过程中要以适当的力充分震捣混凝土，使其与混凝土结合良好，以获得最佳的止水效果。pvc塑料止水带施工注意中要注意一些问题，由于混凝土中有许多尖角的石子和钢筋，操作是要注意避免对止水带造成机械损伤。在定位塑料止水带时，要使其与混凝土界面贴合平整，不能出现止水带翻转、扭曲等现象，否则应及时进行调正在浇筑固定止水带时，应防止止水带发生偏移，影响止水效果。
eva plastic water stop belt is mainly used for concrete pouring, set up in the construction joints and deformation joints and concrete as one of the basic engineering. such as tunnel, culvert, aqueduct, dam, reservoir structures, underground facilities, etc.. the construction method of pvc plastic water stop belt is the same as that of common rubber water stop belt. in the pouring buried to make it smooth and fit the concrete interface, the joint part of the adhesive fastening, pouring process to buried in an appropriate capacity of fully vibrating concrete, the good combination with concrete, in order to obtain the best sealing effect. pvc plastic water stop construction should pay attention to some problems, because there are many sharp stones and steel reinforcement in the concrete, the operation should pay attention to avoid mechanical damage to the water stop belt. in the positioning of the plastic waterstop, to make it smooth and fit the concrete interface, can not appear waterstop flip, twist phenomenon, otherwise should be timely adjusted is pouring fixed sealing strip, should prevent the waterstop shift, affecting sealing effect.
