三、塑料止水带施工方法注意事项
Three, plastic waterproof belt construction method matters needing attention
塑料止水带施工方法与橡胶止水带相同。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，以获得较佳的止水效果。
The construction method of plastic water stop belt is the same as that 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.
（1） 在施工过程中，由于混凝土中有许多尖角的石子和钢筋，操作是要注意避免对止水带造成机械损伤。
(1) in the process of construction, because there are many sharp stones and steel bars in the concrete, the operation should pay attention to avoid mechanical damage to the water stop belt.
（2） 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。
(2) 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.
（3） 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。
(3) when pouring the fixed water stop belt, the water stop belt should be prevented from offset and the sealing effect will be affected.
（4） 塑料止水带接头可利用粘接、热焊接等方法，保证接头牢固。
(4) the joint of plastic water stop belt can be bonded and heat welded, so as to ensure the joint firmly.
（5） 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。
(5) in the process of pouring concrete, attention should be paid to full tamping to achieve the full combination of water stop belt and concrete.
