HDPE reinforced winding pipe series pipe is a plastic instead of steel, plastic instead of cement replacement products, has been widely used in Europe, the product is suitable for a variety of geographical and geological conditions of different soil environment, different depths of underground burial, the following small series to introduce to you HDPE reinforced winding pipe construction technology!

Polyethylene plastic steel spiral wound pipe (SRWPE) is made of steel-plastic composite special-shaped strip by spiral winding welding (extrusion welding on lap joint), its inner wall is smooth and flat, and the specification is DN200-DN2600mm. This kind of pipe has the advantages of corrosion resistance, light weight, easy installation, large flow rate, long life (50 years), etc., and can replace pipes made of high energy consumption materials (cement, cast iron, ceramics, etc.), which is an environmentally friendly green product.

HDPE reinforced winding pipe is a high-tech composite pipe product with independent intellectual property rights, world-leading level, green environmental protection, energy saving and consumption reduction. HDPE reinforced spiral pipe is mainly used as a buried drainage pipe, which integrates the rigidity of steel belt and the corrosion resistance, low friction resistance and wear resistance of polyethylene.

HDPE reinforced spiral wound pipeThe general construction process is as follows: construction preparation→ measurement pay-off→ pipe trench, well chamber excavation→ trench acceptance→ pipe trench cushion (well chamber construction→), pipeline laying→ pipeline connection→ sealing between the pipeline and the well chamber→ partial backfill→ closed water test→ concealed acceptance→ all backfill.

After the excavation of the pipe trench, the construction of the concrete inspection well runs through the whole pipeline construction process, and the construction period is relatively long, so the pipeline laying and the construction of the well chamber are generally carried out at the same time, and there is no strict sequence, but it should be ensured that the pipeline has been laid in place before the reinforcement binding of the well chamber wall, so as to avoid the position deviation caused by the reserved hole.

If it is for some soil conditions are poor, and the groundwater level is also high soil conditions, then it should be excavated in layers, for the pipe base of HDPE reinforced winding pipe also has a series of requirements, should lay a layer of sand with a thickness of about 20 cm, the purpose of this is to increase HDPE enhances the contact area between the bottom of the spiral pipe and the ground, thus effectively protecting the pipe.
