How to wrap the downpipe?

I have used this product upstairs, and you won't know until you use it. It may be an exaggeration to pack the downpipe in five minutes, but since it is a finished product, it can be completed in half an hour. Secondly, others have not denied that you can use bricks to wrap the downspout. Some people just have resistance to new things. There is a process of acceptance. For example, who would have thought of using a gun nail in the previous carpentry? Tenon joints, round nails, etc., to put it more closely, asphalt was used for waterproofing in the past, which was considered reliable. Until 25, I saw someone using traditional asphalt for waterproofing. Who would have thought that cement-based modified asphalt (including coiled material)

would be used for waterproofing? In particular, a few thin layers of cement-based brush, many people think it is unreliable and contradictory, but now? More recently, people used to think that

it would be nice to build a wall with bricks, but now? Gypsum board partitions and ceilings are deeply rooted in people's hearts, just because the construction is convenient, time-saving, area-saving and cost-saving. There are still many materials, such as tile glue, nail-free glue, etc., which are gradually being used now, and there is always a process of accepting new products.

This partition does have some innovations compared with the traditional brick sealing downpipe (as long as the product has passed the national formal inspection, it should be believed that it can apply for a patent, and the patent office is not for nothing, right? ):

1. Time saving: let's not say 5 minutes, let's say half an hour. It's not good to seal a water pipe with a traditional brick or keel and Ette board for half an hour. A worker will work for at least half a day, and it doesn't contain ash, especially Ette board. After sealing, it is necessary to hang a net for ash, which is not as good as brick wrapping. Maybe you will say that I don't need to glue with ceramic tiles, so I laugh without saying a word. Furthermore, the steel keel will corrode for a long time in a humid environment, and the wooden keel will also decay, resulting in a very weak base. Especially for projects that are in a hurry, this can be said to have robbed a lot of time. You wrapped it in bricks, and how many days will it take after the ash is approved? After that, the next step can be started, especially now some bathrooms are designed by designers and have wood finishes, and exterior paint is useful, so you can wait slowly and dry it thoroughly, or you will wait for moldy repair.

2. Cost saving: Everyone knows that saving time saves a lot of costs. What's more, the cost of this pipe itself is almost the same as that of adding water and sediment to bricks, and the secondary handling cost of brick and sand is definitely incomparable with this finished pipe. Bricks and sand wrapped in a water pipe can't get to the job site alone at a time, can you? Not to mention this tube, you know that a tube is only 3 kg, not kg. One person can do it at a time, which saves the cost of handyman, a lot of working hours and costs. Similarly, your bricks and sand are mixed with cement sand to ensure the quality. Haha, this partition seems to be installed, and you can go directly to the next step.

3. Don't worry: it's unprofessional to say that the riser inspection port can be completely reserved. Brother, you didn't supervise the project, did you? You don't want the hidden acceptance of the project, do you? Or you can tell the owners who don't know how to do it in one sentence. I have never seen the riser blocked for many years, and this situation is at most one in 1,. Speaking of national standards, I don't know if you understand it. I want to know something about civil water supply and drainage. He left a riser access, and you? It's ridiculous to erase the normative practices of others. Of course, many home improvements have closed the manhole for the sake of beauty, which is actually a hidden danger. Even if this guy says it's a one in 1, chance, maybe this one just falls in your house, haha, that would be a tragedy. . . Don't say that you have suffered losses, but wait for a lawsuit. What's more, this situation is far more than one in 1,. Once the riser is blocked, the holes in your house, such as floor drain, toilet, squatting, etc., become water outlets, and it is sewage upstairs. Do you know what sewage is? Shit, urine, oil and so on, and haven't passed through the septic tank sewage, and your home has become a septic tank. Hey, but the downspout is bricked again. What should I do? Smash it. If it is bricked before smashing, it will definitely break the downspout. Then discuss it with the upstairs. Don't go into the water for a day. If you eat outside and shit outside, upstairs may agree. Ok, then do you cover food and accommodation? Wow, look, there are dozens of families above. . . .

4. environmental protection: the state has explicitly banned the use of red bricks for many times.

my humble opinion.

too much. . . I won't say how many years I've been working on the project, but the safety, quality, cost and schedule control of a decoration project should be < P > familiar. How many home improvements have been made in a year, but if I do 4 home improvements a year and show them off, I think I'm not the only one who laughs in front of the computer. You said that this material is not firm. If you knock it with a hammer every day, it will be broken if it is made of iron. This material is stronger than the kitchen flue (except the outdoor independent flue well) in the home, and it is thicker than the flue. The fire protection is the same as the < P > level, and it is also an A-level material. Similarly, according to your reason, should the flue be sealed with bricks?
