    HDPE drainIt is a general term for thermoplastic round tubes made of high-density polyethylene resin and made by extrusion molding process without internal pressure. HDPE drain pipe is a replacement product of traditional steel pipe and PVC drain pipe. It mainly undertakes the tasks of drainage such as rainwater, sewage, farmland irrigation and drainage, etc. It is widely used in roads, railway subgrades, subway projects, waste landfills, tunnels. , green belts, sports fields and slopes caused by high water content, such as slope protection, as well as underground irrigation and drainage systems for agriculture and horticulture.






    The principle of the siphonic roof rainwater system is to rely on the design of a special rainwater bucket to implement steam-water separation, so that the rainwater riser is in a full-flow state. When the water in the riser reaches a certain capacity, the siphon effect is generated. During the rain, the entire system was surprisingly quick to remove rain from the roof due to continuous siphoning.


    The same layer of drainage means that the sanitary ware drain pipe (sewage cross pipe and water branch pipe) in the bathroom do not cross the floor to enter the household. The plane construction in the same floor allows the discharge of sewage and waste to meet or exceed the similar and other drainage methods, and smoothly enters the drainage main pipe (main sewage vertical pipe). Once the need to clear the cleaning, it can be solved in this layer. The drainage method of the problem.


    Performance characteristics:


    Drainage safety:


    The orifice is located in the trough. Due to the two-way action of the wave crest and the filter fabric, the orifice is not easily blocked, ensuring the smooth flow of the water permeable system.


    Corrosion resistance:


    Plastics are less prone to rust than soft spring drains.


    Organic combination of strength and flexibility:


    The unique double corrugated structure effectively increases the external pressure strength of the product, and the drainage system is not affected by external pressure deformation and affects the drainage effect.


    Economic type:


    Compared with other drains of the same diameter, the price is lower.


    Product Usage:


    1.Vertical and horizontal drainage and permeable of highways;


    2. Vertical and horizontal drainage of the back and side channels of various retaining walls of expressways;


    3. Drainage of tunnels and underground passages;


    4. Municipal engineering, water purification plants, sewage plants, garbage dumps, etc.


    5.Drainage of resting green spaces such as golf courses, sports fields, parks;


    6.Hillside land development slope water and soil conservation;


    7.Underground drainage of land preparation works;


    We have the domestic leading technology to produce siphon drainage system / compared to the traditional compartment drainage treatment. The most fundamental concept change of the same drainage scheme is to get rid of the restraint between adjacent floors through the reasonable layout of the pipeline inside this layer. It avoids a series of troubles and hidden dangers caused by the drainage horizontal pipe encroaching on the lower space, including unclear property rights, noise interference, leakage hazards, space limitations, etc., while using wall-mounted sanitary appliances, there is no any sanitary corner on the ground. Cleaning and cleaning becomes extraordinarily convenient.


    The same layer drainage is a novel technology in the bathroom drainage system. The drainage pipe is laid in this layer. A common water-sealing pipe fitting is used instead of many P-bends and S-bends. The overall structure is reasonable, so it is not easy to block and easy. Clean up and dredge, users can personally arrange the position of the bathroom ware/siphon phenomenon according to their own hobbies and wishes. It is caused by the attraction and difference between liquid molecules.


    That is, using the water column pressure difference, the water rises and then flows to a lower position. Since the nozzle surface is subjected to different atmospheric pressures, the water will flow from the pressure side to the pressure side until the atmospheric pressure on both sides is equal, the water level in the container becomes equal, and the water stops flowing. The water in the container can be quickly withdrawn by siphoning.


    The siphonic roof rainwater drainage system is a water head generated by using the height difference between the building and the ground. After accurate calculation, the pipe configuration is adjusted to balance the pressure and flow rate of the pipe network. In the design state, the pipe is filled with water to generate a siphon. The system of rapid discharge of rainwater is essentially a multi-bucket pressure flow rainwater drainage system whose basic hydraulic principle is the Bernoulli equation.


    The main working principle of the system is to rely on the unique rainwater bucket design. In the initial stage of rainfall, when the roof rainwater height does not exceed the height of the rainwater bucket, the working condition of the whole drainage system is the same as that of the gravity flow drainage system. As the rainfall continues, when the roof rainwater level exceeds the rainwater bucket height, the scientifically designed anti-whirlpool bucket is used to control the rainwater flow into the rainwater bucket and adjust the flow regime to reduce the vortex, thus greatly reducing the rainwater entering the drainage system. The amount of air entrained makes the drainage pipe in the system full of flow and utilizes the height of the building roof and the potential energy of the rainwater to form a siphon effect when the continuous flow of rainwater flows through the rainwater suspension pipe and falls into the rainwater riser.
