Material novel, reasonable structure, high strength product structure using beam force principle, increase the moment of inertia, ring stiffness improved, so that the emergence of high-strength double-wall corrugated pipe mechanical properties. Test results obtained by: Bellows diameter vertical deformation rate of 3.14% on average, its tube top load up to 60 tons. Bellows and flat wall pipe compared with light weight, saving materials, reducing energy consumption characteristics in the same load premise, and the same material, same size solid wall pipes can save about 40% compared to the raw material wall bellows Internal smooth traffic flow, (compared to cast iron pipe and concrete) using small caliber inner wall roughness coefficient of 0.009 with public traffic and concrete pipe roughness coefficient 0.013, in the case of the same diameter, double-wall corrugated Water flow tube 30% larger than the concrete pipe, hydraulic tests drawn three points; 1, with diameter, under the same flow conditions, the bellows can be reduced slope, reduce depth; 2, in the same caliber, the same Under slope conditions, increase traffic, increase the water capacity of the pipe; 3, with the lower flow conditions, plastic bellows can use small-diameter tube. Pipes using flexible interface, engage in uneven subsidence strong particularly suitable for use in environments with poor ground conditions. Interface with socket seal pipe connections, the construction site is extremely easy handling (500 or less), reduce construction labor intensity, speed up the construction progress of resistance to chemical corrosion, can use a special occasion, insulation resistance> 2300M; 2, pressure test> 2500V; 3, hit the empty test frequency> 35KV; 4, within the scope of the power supply system, the use of low material cost public diameter 160 mm diameter PVC-U double-wall corrugated pipe than chlorinated polyvinyl chloride (CPVC) pipe 70 about%. The inner tube does not scale, do not dredge, reduce maintenance costs in general, do not need concrete foundation construction, general engineering, low cost, long life
