Analysis: The difference between the same layer drainage system and the traditional drainage system

We all know that due to the application of the same layer of drainage system, the drainage system of the same layer has now completely eliminated the traditional drainage system and is increasingly accepted by users. What are the differences between the same layer drainage system and the traditional drainage system? Many people do not understand it. The most fundamental difference is that there is no need for old-fashioned P-bends and old-fashioned S-bend water traps for water drainage in the same floor. The traditional way of draining water is to add a P-bend or S-bend water seal to each sanitary appliance. The old P-bend and the old S trap are the most prone to clogging, which is the biggest drawback of the traditional drainage method. The use of customary thinking to look at the drainage of the same floor is a place where people do not understand the same floor drainage. Here I just like to know together under the same layer drainage system differs from traditional drainage systems which it!

Same floor drainage system definition

The same layer drainage system means that the drainage pipe of the sanitary device does not pass through the floor, and the drainage cross pipe is connected to the drainage riser in this layer. The advantages of the same layer of drainage technology are: clear in the production sector, less disputes over property rights, pipeline maintenance does not interfere with the lower occupants, bathroom hygiene appliances are arranged flexibly, installation is convenient, drainage noise is small, and pipes do not dew.

Water drainage system classification

The domestic same-layer drainage technology can be divided into three types according to different drainage horizontal pipes, different laying positions and pipe fittings:

1) The wall concealed same-layer drainage system is characterized in that the flushing water tank and the water supply and drainage pipe of the toilet are concealed in the wall;

2) The drainage system of the same layer of the drainage water collector is characterized in that a drainage water collector is arranged in the overhead layer of the floor slab, and the drainage pipes of the sanitary appliance are all connected to the drainage water collector and discharged centrally;

3) The common domestic drainage system, sub-decrease floor method and toilet floor local improvement method are two types. Drainage collectors have been developed with the same drainage system.

The same layer of drainage system design points

1) Wall concealed same layer drainage system

Domestic sewage and waste water gravity discharge; sanitary wares are arranged on the same side wall or adjacent wall surface; concealed brackets are set inside the wall; sanitary ware is fixed on the concealed bracket; toilet flush tank is concealed flushing water tank; Toilets are suspended (or wall-mounted); HDPE pipes are used for the drainage pipes, and hot-melt and electrofusion are connected; the drainage riser adopts a single riser drainage system, and the riser is laid on the pipeline. Wells; Drainage cross-tube fullness control within 0.5, the toilet drainage diameter dn90mm; sanitary appliances and brackets fixed place, brackets and floor fixed place to take anti-noise transmission measures.

2) Drainage water collector same layer drainage system

Domestic sewage and waste water gravity discharge; Drainage water collectors, horizontal pipes of drainage pipes of sanitary appliances, and drain pipes of water collectors are all laid in floor slabs. Drainage risers are laid in pipeline wells. Generally spiral PVC-U plastics are used. Drainage collector is made of transparent PVC-U, and is composed of multiple sections, but the maximum number is 7 sections. Each section of the drainage manifold can be connected to a drainage pipe of a sanitary appliance, and the drainage of two sanitary appliances cannot be connected within one section. In the pipe, an inspection port is set above each section of the water collector; a U-shaped trap is provided at the connection point between the sanitary equipment drainage pipe and the drainage water collector; the connection between the drainage pipe of the sanitary device and the drainage water collector adopts the pipe top connection method. Fall water is formed to prevent backflow; the cross section of the water collector may be egg-shaped, oval or circular; the water collector is provided with a slope to facilitate drainage and be fixed with the floor.

3) Domestic common drainage system

Domestic sewage and waste water gravity discharge; General use of conventional pipe fittings, pipe fittings without special; pipe can be PVC-U, flexible drainage cast iron pipe; design method, piping layout, pipe selection, etc. can be according to conventional practice; floor treatment has two There are many methods, namely the ground-up method and the falling-plate method, and the drop-plate method is used more; a domestic same-layer drainage collector with a water-sealing device has been developed for this system.

  

The same layer of drainage system

Mainly applies to residential building toilets. Other civil buildings can also refer to use.

What are the differences between the same layer drainage system and the traditional drainage system?

The first difference; the difference in traps.

The same type of drainage system does not use old P-bends and old-style S-bends. However, conventional drainage systems each have P-bends or S-bends. However, the P-bend and the old S trap which are used in the traditional drainage system are the most easily blocked areas, which is also the biggest drawback of the traditional drainage system.

The second difference: the laying of the drainage cross pipe is different

The drainage cross pipe of the same layer drainage system is laid in this layer. However, the drainage cross pipe of the conventional drainage system, including its P and S bends, is required to be laid through the floor slab, which occupies a large space.

The third difference: Different cleaning methods when blocking

Once the pipeline is blocked, the same layer of drainage system can be dredged in this layer, but the traditional drainage system must be dredged to the lower layer.

The fourth difference: noise

When using traditional sanitary ware, the downstairs can hear very loud noises. However, with the same drainage system, downstairs users cannot hear it.

  

In addition, the three advantages of the same layer of drainage system

Advantage 1: Anti-leakage

The placed sanitary appliances do not wear floors, effectively eliminating the leakage of water due to the contact between the roots of the branch pipes and the concrete, and eliminating the hidden dangers of water leakage.

Advantage 2: Water Saving

The same level of drainage system uses concealed water tank technology. It is currently the most advanced water tank accessories, and its water-saving capacity is very strong.

Advantage three: personalized design

Not limited by space, can be freely arranged in the bathroom, can provide multiple solutions for the bathroom, create more use of space with the overall home design style modern living environment, to avoid the need to align the toilet up and down, the building layout is more freedom .

Editor's summary: The above is the introduction of the difference between the drainage system of the same floor and the traditional drainage system. I hope to help friends who have this requirement!
