PVC加筋管与传统排水管相比较 Comparing PVC reinforced pipes with traditional drainage pipes

(1)加筋管属柔性管材,能承受较大的轴向曲折,弹性橡胶圈衔接方式抗渗漏功能好,当地基发生不均匀沉降时也不会呈现渗漏,对软土地基有相当好的适应性。

(2)加筋管的环刚度较高,侧向强度大,耐性好,能够接受较大埋土负载和路面上的其他压力。

(3)加筋管重量轻,便于运送、转移和装卸,给施工带来了极大的便利,减轻了施工人员的劳动强度,并且不必机械吊装作业,加快了施工功率,降低了施工费用。

(4)加筋管内壁润滑,与同口径混凝土管材相比,加筋管可增加近一半左右的流量。润滑的管材内壁不易形成堵塞,可相应地减少查看修理费用,降低了工程本钱。

(5)加筋管衔接装置快捷,即便大口径加筋管,2-3个熟练工人完成一个接口仅需求几分钟。加筋管对根底及回填资料的要求较低,但材质好的回填资料能够大幅度发挥管材的承载才能。

(6)加筋管具有杰出的耐腐蚀功能,不受周围土壤、水质及一般运送介质对管材的侵蚀。加强筋还能够嵌入周围的回填资料中,分管了环境温度变化对管材发生的伸缩作用,使加筋管的正常使用寿命可达50年以上。

 

(1) Reinforced pipe is a flexible pipe that can withstand large axial flexures. The elastic rubber ring connection method has a good anti-leakage function. Leakage will not appear when the ground is unevenly settled, which is equivalent to soft ground. Good adaptability.

(2) The ring stiffness of the reinforced pipe is high, the lateral strength is large, the resistance is good, and it can accept large buried soil loads and other pressures on the road.

(3) The reinforced pipe is light in weight, convenient for transportation, transfer and loading and unloading, which brings great convenience to the construction, reduces the labor intensity of the construction personnel, does not require mechanical lifting operations, speeds up the construction power, and reduces construction costs.

(4) The inner wall of the reinforced pipe is lubricated. Compared with the concrete pipe of the same caliber, the reinforced pipe can increase the flow by about half. The inner wall of the lubricated pipe is not easy to form a blockage, which can correspondingly reduce the inspection and repair costs and reduce the engineering cost.

(5) The connection device of the reinforced pipe is fast. Even for a large-diameter reinforced pipe, it only takes a few minutes for 2-3 skilled workers to complete an interface. Reinforced pipes have lower requirements for the foundation and backfill materials, but the backfill materials with good materials can greatly exert the bearing capacity of the pipes.

(6) Reinforced pipes have outstanding corrosion resistance, and are not affected by the surrounding soil, water quality and general transport media. The stiffener can also be embedded in the surrounding backfill data, which manages the expansion and contraction of the pipe due to changes in ambient temperature, making the normal service life of the stiffened pipe more than 50 years.
