Construction method of plastic water stop belt
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.
4. plastic water stop construction notice
1) in the course of construction, because there are many pointed stones and reinforcing bars in the concrete, the operation should pay attention to avoid mechanical damage to the water stopping belt.
2) in the positioning of plastic water stop belt, to make it and the concrete interface leveling, can not appear "water stop", "flip", "distortion" and so on, otherwise should be timely adjustment.
3) when pouring the fixed water stop belt, the water stop belt should be prevented from shifting and the sealing effect will be affected.
4) the joint of plastic water stop belt can be secured by bonding and thermal welding.
5) in the process of pouring concrete, it is necessary to pay attention to the full shock and tamping so as to achieve the full combination of the water stopping belt and concrete

| 塑料止水帶是由聚氯乙xi樹脂與各種填加劑，經(jīng)混合、造粒、擠出等工序而制成的止水材料。該產(chǎn)品利用彈性體材料具有的彈性變形特性在建筑構(gòu)造接縫中起到防漏、防滲作用，且具有耐腐蝕、耐久性好的特點。塑料止水帶主要用于混凝土澆注時設(shè)置在施工縫及變形縫內(nèi)與混凝土構(gòu)成為一體的基礎(chǔ)工程。如隧道、涵洞、引水渡槽、攔水壩、貯液構(gòu)筑物、地下設(shè)施等。 2．塑料止水帶技術(shù)標(biāo)準(zhǔn) 測試項目性能指標(biāo)硬度（邵爾A），度≥65拉伸強度，MPa≥12扯斷伸長率，%300撕裂強度，KN/m≥25脆性溫度，℃≤-30熱空氣老化70℃×72h拉伸強度，MPa≥10扯斷伸長率，%≥240 | |
| 3．塑料止水帶施工方法 塑料止水帶施工方法與橡膠止水帶相同。在澆埋時要使其與混凝土界面貼合平整，接頭部分粘接緊固，澆埋過程中要以適當(dāng)?shù)牧Τ浞终饟v混凝土，使其與混凝土結(jié)合良好，以獲得最佳的止水效果。 4．塑料止水帶施工注意事項 1） 在施工過程中，由于混凝土中有許多尖角的石子和鋼筋，操作是要注意避免對止水帶造成機械損傷。 2） 在定位塑料止水帶時，要使其與混凝土界面貼合平整，不能出現(xiàn)止水帶翻轉(zhuǎn)、扭曲等現(xiàn)象，否則應(yīng)及時進行調(diào)正。 3） 在澆筑固定止水帶時，應(yīng)防止止水帶發(fā)生偏移，影響止水效果。 4） 塑料止水帶接頭可利用粘接、熱焊接等方法，保證接頭牢固。 5） 澆注混凝土過程中要注意充分震搗，以達到止水帶和混凝土充分結(jié)合 淮南》EB350*6 PVC止水帶
