Reinforced spiral wound pipe series pipe is a replacement product of plastic instead of steel and cement with plastic, which has been widely used in Europe, reinforced winding pipeIt is suitable for underground burial in various soil environments with different geographical and geological conditions and different depths. Because the pipe has good flexibility macroscopically, it is the load-bearing structure of the system of "pipeline and soil filling", and has strong rigidity in the local pipe section, therefore, in the pipeline construction process, there is no need to set up concrete cushion or concrete pipe base, and can be laid directly in the trench, and can basically be done while excavating, while the pipe is down, and the backfill is achieved, the construction period is saved, the construction procedure is simplified, manpower and material resources are saved, and the economic and social benefits are significant.

In terms of strength and stiffness, on the surface, the winding reinforced pipe is not as good as the concrete pipe, especially the reinforced concrete pipe, but in practical application, because the HDPE winding reinforced pipe is a flexible pipe, as long as the design and construction are done properly, it can bear the load together with the surrounding soil, and it is lighter than other pipe materials under the same application conditions, easy to transport, and is safer, more convenient and faster than the construction of cement pipes and steel pipes, and can significantly reduce the cost.

Main specifications of reinforced spiral hose:

(1) Vertically pressurized to 40% of the outer diameter, immediately unloaded, the sample will not be ruptured, and no delamination.

(2) Under the condition that the temperature is 0 °C and the height is 1M, the weight of 1Kg is used to impact 10 times, and there should be no cracking for more than nine times.

(3) The inner wall is uniform and smooth, the permeable holes are evenly beaten below 1/2 of the trough height, and the number of holes hit above 1/2 of the trough height is not more than 10% of the total.

(4) Permeable area≥ 45cm2/m.
