钢带增强管特点是什么?

What is the feature of steel strip reinforcement pipe?

贵州波纹管

HDPE钢带增强管特点良好的卫生性能:PE管加工时不添加重金属盐稳定剂,材质无毒性,无结垢层,不滋生细菌,很好地解决了城市饮用水的二次污染。卓越的耐腐蚀性能:除少数强氧化剂外,可耐多种化学介质的侵蚀;无电化学腐蚀。

HDPE steel reinforced pipe health good performance characteristics: the heavy metal stabilizer without adding PE processing, material non-toxic, no dirt, no bacterium, is a good solution to the pollution of the city drinking water two times. Excellent corrosion resistance: except for a few strong oxidant, can withstand a variety of chemical erosion medium; no electrochemical corrosion.

贵州波纹管认为长久的使用寿命:在额定温度、压力状况下,PE管道可安全使用50年以上。较好的耐冲击性:PE管韧性好,耐冲击强度高,重物直接压过管道,不会导致管道破裂。可靠的连接性能:PE管热熔或电熔接口的强度高于管材本体,接缝不会由于土壤移动或活载荷的作用断开。良好的施工性能:管道质轻,焊接工艺简单,施工方便,工程综合造价低。

Guizhou bellows believe that long service life: PE pipes can be safely used for more than 50 years at rated temperature and pressure. Good impact resistance: PE pipe has good toughness, impact resistance, high strength, heavy direct pressure through the pipe will not cause pipeline rupture. Reliable connectivity: PE pipe or fused interface strength is higher than that of the pipe body, the seam is not due to soil movement or live load disconnect. Good construction performance: light pipe, simple welding process, convenient construction, low comprehensive cost of engineering.

注意事项做好临时排水与设计排水系统相结合,保持现场排水设施的畅通,避免积水与冲刷边坡。做好基坑内排水措施,防止泡槽,严禁带水作业。应尽可能缩短开槽长度和施工周期,做到成槽快,回填快。一旦发生泡槽,应及时将水排除,把受泡的软化土层清除,换填砂石料,做好基础处理。

Attention should be paid to the combination of the temporary drainage and the design drainage system, to keep the drainage facilities unblocked, and to avoid the water accumulation and the erosion of the slope. Do a good job in the foundation pit drainage measures to prevent the bubble slot, strictly prohibit water operation. The length of slotting and the construction period should be shortened as much as possible, so as to achieve fast groove and fast backfilling. Once the bubble occurs, the water should be removed in time to remove the softened soil from the bubble and replace the sand stone for basic treatment.

翡翠棋牌应采取措施防止管材漂浮。可先回填土到管顶以上大于一倍管径的高度。当管道安装完毕尚未还土时,一旦遭到水泡,应进行管中心线和管底高程复测和外观检查,如发生位移、漂浮,拔口现象,应返工处理。应采取防结冰措施。可以用草帘子、棉被等简易保温材料铺设在槽底。另外,钢带波纹管在使用中对于沿海城市等地下水位较高的工程,应加大力度采取降水措施,在槽底设置排水沟和集水井,做好槽底降水。

Measures should be taken to prevent the pipe from floating。 The height of the fill to the top of the tube is more than twice the pipe diameter。 When the pipeline has not been installed yet, once the blistering happens, the height of the center line and the bottom of the pipe should be rechecked and the appearance check should be carried out。 For example, displacement, floatation and extubation should be reworked。 Anti icing measures should be taken。 Simple insulation materials such as grass curtains and cotton quilts can be used in the bottom of the trough。 In addition, when the steel bellows are used, for the coastal cities and other high groundwater level projects, we should intensify efforts to take precipitation measures, set up drainage drains and collecting wells at the bottom of the trough, and do well in the bottom of the trough。

对于重要的工程最好是采用两种以上的方法组合施工,保证连接的安全可靠。组合的方式有多种,举例如下:连接与热风挤出焊接组合使用法。先用热风挤出焊,把管材焊接起耒、达到不漏的要求,再包热收缩管,达到保险可靠。连接与正试验的卡箍连接方法组合使用。先缠热收缩带或包热收缩管,再用卡箍锁紧,达到保险可靠。

翡翠棋牌For important projects, it is best to use more than two methods to combine the construction, so as to ensure the safety and reliability of the connection。 There are many ways of combination, for example, connection and hot air extrusion welding combined use method。 First with hot extrusion welding, the welded pipe has not reached the requirements of Lei, leakage, then pack heat shrinkable tube, to achieve safe and reliable。 The connection method is used in combination with the clamp connection method of the positive test。 The heat shrinkable belt or heat shrinkable tube is first wrapped, and the clamp is used to lock the pipe, so as to ensure the reliability of the insurance。
