350mm寬PVC塑料止水帶施工技術(shù)
PVC塑料止水帶是由優(yōu)級聚氯乙烯樹脂與各種化工填加劑，經(jīng)混合、造粒、擠出等工序而制成的止水帶產(chǎn)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樹脂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。
It makes full use of the elastic debation 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。塑料止水帶充分利用聚氯乙烯樹脂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。
PVC plastic water stop belt is mainly used for concrete pouring, set up in the construction joints and debation 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 debation 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 b
PVC塑料止水帶施工方法與橡膠止水帶的施工方法是相同的。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。
The construction b of PVC plastic water stop belt is the same as the construction b 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.
施工注意事項：
Matters needing attention in construction:
用戶在施工過程中，由于混凝土中有許多尖角的石子和鋼筋，操作時要注意避免對塑料止水帶造成機械損傷。
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。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。止水帶接頭可利用粘接、熱焊接等方法，保證接頭牢固。澆注混凝土過程中要注意充分震搗，以達(dá)到止水帶和混凝土充分結(jié)合。
In the bing 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 b 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.
