Technical Field
The invention relates to the field of drainage pipes, in particular to a drainage pipe and a multi-blade reinforcing rib spiral type drainage plastic pipe system.
Background
In residential buildings in recent years, the requirements for functional selection and health and environmental protection of building materials have been increasingly highlighted. The traditional water draining pipe is gradually replaced by new spiral water draining pipe product due to the problems of water pressure and noise. At present, drainage system products made of two materials are widely used in the market. One is that the joints of the existing polyvinyl chloride spiral drainage pipelines are mutually overlapped and rigidly connected, so that the sound energy cannot be released, and the noise is easy to accumulate and superpose. The pipe wall is thin, the material is hard, and the function of absorbing sound waves is weak, so that the function of reducing noise is not provided, and the requirement of a mute place cannot be met. Meanwhile, in terms of material, the PVC spiral drain pipe plastic pipe is a polyvinyl chloride material, is a waste of chlor-alkali chemical industry and is a toxic material; in terms of installation mode, the PVC spiral drain pipe is glued, easy to damage and age and inconvenient to maintain and replace; in terms of pressure resistance, the PVC plastic spiral pipe is made of materials according to the characteristics of the used materials, so that the PVC plastic spiral pipe is poor in impact resistance and low in pressure resistance; from the aspect of mute effect, the PVC spiral drain pipe has high noise, which is a great problem troubling wide users. The second is a polypropylene or polyethylene spiral drainage pipe system which appears in recent years, which has a drainage pipe structure of a single-blade spiral type and a double-blade spiral type, and is improved in material. In particular, the environment-friendly pollution-free polypropylene or polyethylene material is tasteless, odorless and nontoxic, has no pollution to the environment in the production, construction and use processes, and belongs to a green building material. The service life can reach more than 50 years under the normal use condition; meanwhile, the polypropylene or polyethylene spiral drain pipe is not easy to age and convenient to maintain because the linking mode comprises a spiral pressure type link and a socket type link; the inner layer and the outer layer of the polypropylene spiral drain pipe are both made of environment-friendly polypropylene resin with high impact resistance, so that the polypropylene spiral drain pipe has extremely high pressure resistance and impact resistance. And because the polypropylene or polyethylene spiral drain pipe adopts flexible connection, the installation is convenient and fast, and the sound generated when water flow impacts the pipe wall can be prevented from transmitting to the next pipe or pipe fitting to cause resonance, so that the sound can be effectively prevented from being transmitted. And a good mute effect is achieved. However, in view of the structural performance of the conventional single-spiral or double-spiral wall spiral drainpipe in recent two years, the following disadvantages still appear:
1. the number of the spiral blade ribs is insufficient: the single and double helical blade rib structures can make water flow down along the pipe wall, and generate certain silencing effect, but cannot adapt to high-flow-speed water flow. When the spiral pipe is subjected to severe environments such as seasonal or temporary rainstorm and strong rainfall, the middle part of the spiral pipe generates airflow turbulence due to insufficient drainage. Once the turbulent flow is generated, not only the noise is increased, but also the flow velocity is slowed down, and the pressure in the pipe is formed.
2. Although the polypropylene or polyethylene material has stable performance in a natural static state, if the polypropylene or polyethylene material is influenced by various possible condition factors in the installation and use process, long-term external compression occurs, and the polypropylene or polyethylene material is pulled after internal turbulence, so that the damage and the influence are generated on a pipeline system.
3. The drainage in-process often can receive the pouring into of harmful substance rubbish such as solid, liquid, organic, inorganic for drainage pipe system receives destruction and corruption, and especially harmful substance can depend on the helical blade muscle in helical pipe system, and the blade muscle is at present not the enhancement protection that appears.
4. The drain pipe elements in the drainage system do not provide significant effective regulation of flow rate and noise.
5. At present, the artificial intelligence era is entered, and the monitoring measures are also rapidly developed, but until now, no intelligent monitoring facility is available in the spiral drainage pipe system for monitoring.
