双扣聚氯乙烯增强管链接的方式有哪些?

施工过程中,我碰到了很多施工人员不是很了解双扣聚氯乙烯增强管是如何连接的,甚至是很多设计院的设计师,也不甚了解,设计师往往是根据以往设计的管材的经验来设计双扣聚氯乙烯增强管的连接方式。这样做是不严谨的,双扣聚氯乙烯增强管的连接方式多样,具体要根据当地土质、地形、抗压性、施工难易程度、资金预算等等诸多因素来选择更为适合的连接方式。下面我将对双扣聚氯乙烯增强管的连接方式做一个系统的阐述。
During the construction process, I met many construction personnel who did not know how to connect the double buckle PVC reinforced pipe. Even many designers of the Design Institute did not know much about it. The designer often designed the connection mode of double buckle PVC reinforced pipe according to the previous pipe design experience. This is not rigorous. The connection methods of double buckle PVC reinforced pipe are various. The most suitable connection mode should be selected according to the local soil, terrain, compression resistance, construction difficulty, capital budget and many other factors. I will make a systematic exposition on the connection mode of double buckle PVC reinforced pipe.
一:热收缩套连接
1: Heat shrinkable sleeve connection
这是各种排水排污管材里面,更为常用的一种连接方式,起可靠的性能得到了市场的检验。这种热收缩套以塑料橡胶为原料,一次成型的黑色橡胶套,仅适用于所有塑料(HDPE、PP、PVC、PVC-U、PPR等)管材。非塑料管材无法使用。国标检测依据GB/T18477.2-2011 、PrEN13476-1:2006,其兼容性好、造价低、施工难度适中,所需器械设备:喷枪、液化气罐,连接固定效果好,闭水实验突出。是目前主流的一种连接方式,这种连接方式,很适用与双扣聚氯乙烯增强管的连接

This is the most commonly used connection method among all kinds of drainage and sewage pipes. Its reliable performance has been tested by the market. This kind of heat shrinkable sleeve is made of plastic rubber. The black rubber sleeve is only applicable to all plastic pipes (HDPE, PP, PVC, PVC-U, PPR, etc.). Non plastic pipes cannot be used. According to GB / t18477.2-2011 and pren13476-1:2006, it has good compatibility, low cost and moderate construction difficulty. The required equipment: spray gun, liquefied gas tank, good connection and fixation effect, and outstanding closed water experiment. It is a mainstream connection mode at present, which is very suitable for the connection with double buckle PVC reinforced pipe
二:不锈钢卡箍连接
2: Stainless steel clamp connection
不锈钢卡箍作为排水排污管中常见的一种连接方式,同样得到了市场的认可。不锈钢卡箍由三部分构成,更外层是不锈钢卡皮,中间层为发泡橡胶板、里层为密封套。不锈钢卡箍连接适用于外壁光滑的,有一定环柔性的管材。执行标准:GB/T18477.2-2011、PrEN13476-1:2006,施工所需器械设备:普通螺栓紧固、扳手,其坚固程度很好,但是闭水性一般。造价要远远高于热收缩套连接。
Stainless steel hoop, as a common connection method in drainage and sewage pipe, has also been recognized by the market. The stainless steel clamp consists of three parts, the outer layer is stainless steel card, the middle layer is foam rubber plate, and the inner layer is the sealing sleeve. The stainless steel clamp connection is suitable for the pipe with smooth outer wall and flexible ring. Executive standard: GB / t18477.2-2011, pren13476-1:2006, construction equipment: ordinary bolt fastening, spanner, its firmness is very good, but the water sealing property is general. The cost is much higher than the heat shrinkable sleeve connection.
三、承插胶圈连接
3、 Socket rubber ring connection
说实话,这种连接方式我是很反对用在双扣聚氯乙烯增强管上的,但是我看到有一些地方的设计院设计的就是这种连接,很是无耐啊。因为双扣聚氯乙烯增强管是连续缠绕的,不可能做一个子母口的扩口,它不跟HDPE管一样一体成型。承插口以PVC-U缠绕管为例,承插胶圈是由PVC为原材料,在原有管道口径基础上进行扩口,在扩口内壁附着橡胶圈或者毛毡。根据管道材质,适用于塑料管材、铸铁管、水泥管等绝大多数管材。GB/T19472.2-2007,施工所需器械设备:吊机、吊装带、润滑油、闭水胶粘。闭水性差,成本很高。所以真正懂管道的人,是不会设计这种连接方式用在双扣聚氯乙烯增强管上面的
To tell you the truth, I am very opposed to the use of double buckle PVC reinforced pipe. However, I can see that some design institutes in some places have designed this connection, which is very intolerable. Because the double buckle PVC reinforced pipe is continuous winding, it is impossible to make a child and mother mouth expansion, it is not the same as HDPE pipe integral molding. The bell and spigot take PVC-U winding pipe as an example. The bell and spigot rubber ring is made of PVC as raw material and expanded on the basis of the original pipe diameter. Rubber ring or felt is attached to the inner wall of the expansion. According to the pipe material, it is suitable for most pipes such as plastic pipe, cast iron pipe and cement pipe. GB / t19472.2-2007, equipment required for construction: crane, lifting belt, lubricating oil, closed water adhesive. The cost is very high because of its poor sealing property. Therefore, people who really understand the pipeline will not design this connection method to be used on the double buckle PVC reinforced pipe
