350mm宽PVC塑料止水带施工技术
PVC塑料止水带是由优级聚氯乙烯树脂与各种化工填加剂，经混合、造粒、挤出等工序而制成的止水带产品。
PVC plastic waterstop is composed of grade PVC resin and various chemical additives, water mixing, granulating and extruding process and made with products.原理
principle
它充分利用聚氯乙烯树脂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，且具有耐腐蚀、耐久性好的特点。
It makes full use of the elastic deformation property of PVC resin, and has the function of anti leakage and seepage prevention in the joint of building structure, and has the characteristics of corrosion resistance and good durability.
用途
purpose
PVC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。塑料止水带充分利用聚氯乙烯树脂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，且具有耐腐蚀、耐久性好的特点。
PVC 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 plastic water stop belt makes full use of the elastic deformation property of PVC resin to prevent leakage and prevent seepage in the joint of building structure, and has the characteristics of corrosion resistance and good durability.

施工方法
Construction method
PVC塑料止水带施工方法与橡胶止水带的施工方法是相同的。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。
The construction method of PVC plastic water stop belt is the same as the construction method of 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.
施工注意事项：
Matters needing attention in construction:
用户在施工过程中，由于混凝土中有许多尖角的石子和钢筋，操作时要注意避免对塑料止水带造成机械损伤。
In the process of construction, because of many sharp stones and steel bars in the concrete, it is necessary to avoid mechanical damage to the plastic water stop when operating.
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。止水带接头可利用粘接、热焊接等方法，保证接头牢固。浇注混凝土过程中要注意充分震捣，以达到止水带和混凝土充分结合。
In the positioning of plastic water stop belt, to make it and concrete interface leveling, can not appear water stop belt, twist and other phenomena, otherwise should be timely adjustment. When pouring the fixed water stop belt, the water stop belt should be prevented from offset and the sealing effect will be affected. The joint of the water stop belt can be bonded by using the method of heat welding, so as to ensure the joint firmly. In the process of pouring concrete, attention should be paid to fully tamping to achieve the full combination of water stop belt and concrete.
