Secondary drainage renovation? 10. Secondary drainage decoration?

The bathroom is a place with a lot of water, so it is necessary to do a good job of waterproofing the bathroom. When we buy a house, the developer will generally do waterproof and drainage work in the bathroom. Therefore, when decorating, some families will choose not to do secondary drainage work in order to save trouble.

First, the importance of secondary drainage in the bathroom.

Speaking of secondary drainage in the bathroom, there may be many people who don't understand it very well, to put it simply: the floor drain on the ground is a drain, and the floor drain is called secondary drainage. Because the toilet drainage is generally discharged through the floor drain, but there is also water that will seep directly into the caisson from the floor tiles, day after day, more and more water in the caisson, if the secondary drainage is done, the caisson can be successfully discharged.

A sunken toilet means that when the main body is built, the toilet and the floor will also suffer.

3. In the above two situations, if there is a secondary drain at the bottom of the box, when the water level exceeds the height of the secondary drainage, it will be discharged from the secondary drainage, and will not leak due to the increase in pressure and the bottom of the box will leak or make the water level rise and overflow out of the bathroom and soak into the wall root of each room.

3. How to do the secondary drainage of the bathroom?

1. First of all, do a good job of waterproofing before the bathroom is backfilled, and it is best to use flexible colored waterproofing. Flexible waterproofing is more resilient, and even if the wall naturally shifts and pulls up over time, it will not cause cracks in the corners; The colored waterproof is more recognizable, allowing people to see the waterproof coverage area at a glance, and avoiding the corners and corners caused by visual neglect. Then irrigate for a 48-hour closed water test, and the next step can only be carried out if the test is qualified and there is no water leakage.

2. Then, according to the actual structure and area of the bathroom, it is divided into a number of fixed frames with wooden squares (the size is determined by the actual situation, and there is no strict size standard), and watered.

Summary: Secondary drainage is an effective step to prevent water seepage and leakage, which is different from ordinary waterproof operation, more rigorous, and reduces the trouble of later maintenance.

Drainage refers to artificially controlling the flow direction of water and artificially draining it. Measures to eliminate and dispose of excess water. Farmland drainage is one of the important measures to improve agricultural production conditions and ensure high and stable crop yields.

Principle:

In order to control the water table, field drainage ditches with a certain spacing and depth must be excavated. In the case of a given depth of drainage ditch, to meet certain drainage requirements, the smaller the spacing of drainage ditches, the faster the groundwater declines, and the greater the decline value of the groundwater level in a certain time.

The secondary drainage of the toilet is a design method to prevent the leakage of the water pipe or the floor at the bottom of the toilet from leaking. After all, there will be leakage or sediment accumulation in the bathroom when water is used for a long time, and the soaking of cement for a long time will more or less penetrate into the downstairs, so that secondary drainage can solve this problem well.

The secondary drainage in the bathroom is the first level of leakage, and it is the "goalkeeper" of waterproof and leak-proof toiletsIt has an important effect on the moisture-proof and leak-proof work of the toilet floor! However, despite the importance of setting the function of secondary drainage, there are still many good friends who seem to be less convinced of the need for secondary drainage in the bathroom. Therefore, this process is ignored when decorating the bathroom, so as to increase the probability of leakage and regret not setting up secondary drainage!

The toilet has been decorated and there is a leakage, or there is a concern that there will be leakage because there is no secondary drainage, and the interior is renovated and you want to set up a secondary drainage. In the case that such a thing does not destroy the decoration in the bathroom, Brother Yu proposes to solve it from the wall! However, Brother Yu also has to state in advance that this kind of operation steps are suitable for self-built houses in rural areas, because it is not safe and expensive to work in the walls of multi-storey buildings, and people will not allow you to punch holes in the walls to drain the waste water caused by the leakage of the toilets.

Operation process: If you forget to set up secondary drainage in the toilet of your rural self-built house, and you are worried or there is a potential leakage safety hazard, we can open a hole in the outer wall from the bottom end of the toilet to drain the water from the bottom of the toilet from the wall. This kind of practice is mainly to drain the water that may be soaked underneath, which has a certain moisture-proof and leak-proof effect!

It depends on what the toilet looks like, some toilets are rectangular in strip form, some are square, and some are not very standard, or fan-shaped ......; Some toilet drainage pipes are generated by a unified design plan or a standardized design plan in the early stage of engineering construction; Some toilet drains are planned and designed by the customer independently, which is not the same.

According to its own scope of application, if the toilet is in the form of a strip, the slope angle of road drainage is very large, which is not conducive to the anti-skid of the ground; If the viewing angle is too small, the drainage will be slow, and it is inconvenient to immediately drain and clean the sanitation, and you can also do secondary drainage. For example, in the interior decoration, according to the total area, direction, and appearance, according to the reality, the drainage pipe branch connector must be assembled in advance on the downward pavement, that is, the drainage outlet must be pre-embedded; and divide the total area of the toilet into two or one into three, which is in line with it; Each is used as a face, laundry, shower, and toilet. Even if it is applied at the same time, it affects each other, and the drainage is convenient.

If the total area of the toilet is too small and standard, there is no need for secondary drainage.

If the bathroom has been renovated, it can still be used for secondary drainage; First of all, you need to lay the pipes according to your own home and house type, and secondly, you need to make the drain for secondary drainage, and then you need to level and make a waterproof layer again, and then you can get some floors to support the bathroom, or backfill directly on the top of your head.

It can't be done, it's already renovated, and it can't be moved anymore. If you want to do secondary drainage, knock the tiles off.

It is possible to do secondary drainage, and it is necessary to renovate some things that have been renovated to determine the situation of the line, which will definitely affect the aesthetics.

Toilet secondary drainage method:

1. First of all, make a hole in the main drainage pipe, install the drainage pipe, and pay attention to the same height as the waterproof layer of the original sinking layer.

2. Start to do the sinking layer treatment, and when you do it, you should do the slope work according to the leveling of the drainage pipe mouth, and then brush the waterproof paint twice.

3. When laying pipes, start to make partitions, and consider the location of the pipes to be laid.

4. Use ceramsite with good drainage to do backfill work, then lay steel bars, and then do concrete treatment.

5. Finishing work: first brush the waterproof twice on the bathroom floor, and then do cement slurry treatment.

Precautions for secondary drainage.

1. When the installation of the secondary drainage outlet is completed, it is necessary to find the slope in time. On top of the slope layer, it is necessary to re-do an effective layer of waterproofing.

2. When the leveling layer and drainage outlet are all completed, it is recommended to do a closed water test. In this case, the drain is blocked and the liquid level is observed to drop.

3. After the closed water test is completed, open the drain to observe whether the water can flow out completely. If the water is stored at this time, it means that the slope is unqualified, and the slope must be re-founded.

4. During the construction of the sunken toilet, it is necessary to pay attention to the protection of the drainage outlet and the waterproof inside the caisson. Because no matter how good the installation is, it will affect its use if it is damaged in the later stage.

After the waterproof work has done the irrigation test up to the standard, the protection of the waterproof layer is gradually in the work, in fact, the road surface is to find the inclination, and at the same time set up the secondary drainage pipeline, which is generally to punch the external secondary drainage pipeline on the main drainage pipeline, and the key to the inclination of the road surface is to make all the drainage methods to the secondary drainage outlet, and at the same time the slope layer can also be used as the protective layer of the waterproof layer (mixed mortar to find the slope). In the future, we can make another layer of structural reinforcement waterproofing layer! The next work is to design the walls and floors (according to the actual situation, the wall decoration should be done first, and then the above work can be carried out).

If they forget to set up secondary drainage in the bathroom of their rural self-built house, and are worried or have already appeared water leakage safety hazards, we can cut a hole in the outer wall from the bottom of the bathroom to drain the water from the bottom of the bathroom. The key to these practices is to drain out the water that is likely to seep into the bottom, bringing a certain waterproof and leakage effect! It is a very standardized method to set the secondary drainage from the bottom of the bathroom, but because it is actually operated after the interior decoration of the bathroom, it should be paid attention to the sealing problem.

Punching holes under the concrete floor slab is actually waiting for the leakage to occur immediately, so after connecting the pipe, it is necessary to do a good job of sealing the cracks around the periphery, and use a variety of plugging spirits to fill the leaks!

The caisson toilet is the downward type toilet, which refers to the main construction of the toilet solid part or the overall downward move to a certain relative height (generally 35cm-40cm lower than the floor slab of this floor), so that the horizontal drainage pipeline of the toilet is buried in it, and then backfill with light raw materials or cement prefabricated slab empty frame. Secondary drainage is a drainage measure to prevent leakage from the underground water pipe in the internal structure of the toilet and water seepage from the floor to the bottom of the floor. If you only use the toilet to prevent odor and drain drainage, you can't deal with the problem of leakage in the internal structure of the caisson, so you have secondary drainage.

The floor drain installed on the road surface is a drain, and the downward moving toilet caisson is called secondary drainage.

The biggest puzzle is that the caisson toilet has been drained twice, will it be backwater? This one certainly won't. However, if the main pipe is blocked, no matter what the drain is, it will overflow, and if the main pipe is not blocked, it will definitely not be easy to reverse the water.

Why is the internal structure of the caisson capable of water? Because its appearance is completely a pool, it only needs to store water into the caisson, so that the water is also stored in the caisson. Over time, if the internal structure of the caisson is well waterproof and there is no secondary drainage, then the caisson will be filled with water.

You've probably seen a drop-down restroom, where the drain risers are assembled vertically from side to side in certain corners of the caisson. Each drainage riser is connected to the horizontal pipe of drainage through the root of this riser, and finally takes the positioning point of each drainage in everyone's room.

The secondary drainage of the living room is mainly for a sunken toilet, and the floor drain or drainage outlet in the bathroom sink in the fine decoration is called secondary drainage. A floor drain on the floor of the bathroom is called primary drainage. To make a waterproofing layer on the bathroom floor, at this time we can use asphalt waterproofing paint, and then backfill the bathroom with some sand.

Secondary drainage refers to a drainage system carried out in the process of decoration, sorting and waterproofing are very important in the process of bathroom decoration, and attention should be paid to construction and plumbing.

This refers to the operation of a sunken toilet, which can better lay pipes and effectively avoid the problem of water leakage.

Regardless of the new house or the old house, for the bathroom area, it is necessary to do a good job of waterproofing to avoid water leakage, but to avoid water leakage, can only rely on waterproof materials? Here I will share the secondary drainage process of the toilet to create a bathroom that will never leak.

Cement sand, bricks, fine steel bars, waterproof materials (flexible waterproofing is preferred), wooden strips.

01 Do a good job of waterproofing before making a bathroom without backfilling, and it is best to use flexible colored waterproofing. Flexible waterproofing is more tough, that is, the wall will naturally shift and rise over time, and will not cause cracks in the corners; The colored waterproof is more recognizable, allowing people to see the waterproof coverage area at a glance, and avoiding the corners and corners caused by visual neglect.

02 Then, according to the actual structure and area of Weizhou Chifu Shengjian, the frame was fixed with wooden squares, cement mortar was poured, and fine steel bars were put into the undried cement mortar in the frame in a tic-tac-toe shape. The fixation period is about 3-5 days, and water once a day in the morning and evening to avoid drying and cracking. After the water is firmly dry, the wooden frame can be removed.

03 During the air-drying period of the laminate, the other areas are backfilled and leveled in the form of a slight slope, and a drainage outlet is reserved at the lowest slope.

04 After the shelves are made, the toilet is overhead and the shelves are covered above the overhead layer.

05 After the laminate is laid, the leveling treatment is carried out, and then a waterproof painting and 24-hour closed water test are carried out.

06 After the last closed water test was successful, the floor tiles were paved, and the bathroom that never leaked was completed.

It is easy to leak and accumulate water in the sunken bathroom decoration, and if you do secondary drainage, the stagnant water can be drained away. Next, pchouse will share with you how to construct the secondary drainage of the bathroom.

1. First of all, we carry out pipe routing according to the needs and house type of our family.

Of course, it is also necessary to pay attention to the original waterproof layer of the developer when laying pipes, and the pipes are just a simple frame.

Of course, there are actually many people here who have mentioned that it is not possible to destroy the developer's original waterproof layer, but when we do secondary drainage, in fact, the ground has to be leveled, and then the waterproof layer has to be made, so if the waterproof layer on the ground is destroyed, I personally think there is no big problem.

2. Then do the secondary drainage outlet.

Generally, it is next to the main sewage pipe, and the stagnant water from the secondary drainage is discharged along the main sewage pipe.

3. Leveling. In order to facilitate the smooth flow of water into the secondary drainage hole, the ground of the sinking layer should be sloped, that is, the place of the secondary drainage hole is the lowest, and then the other place is slowly raised.

4. Make a waterproof layer.

If the waterproof layer on the wall of the sinking layer is damaged, then it needs to be repaired; After leveling, a waterproof layer should be made on the level.

5. There is basically no big problem in the back, we have to make some lattices to support the bathroom floor, some families will use ceramsite backfill, and there are also direct overhead, both methods are OK. Then there is the construction of the bathroom floor, and the bathroom floor should also be waterproof.
