Sewer is a kind of urban public facility, which appeared as early as in ancient Rome.They picked up some waste in the dump and built a simple "house" to live in. They picked up beds, wardrobes, bookcases, etc.Later, the most magnificent sewer in the ancient world was left to the Romans by the Idalasians:the Cloaca Maxima （the Cloaca Maxima）。Around the 6th century BC, the Edararians excavated the sewers discharging into the Tiber River, whose main roads were more than 16 feet wide, and later expanded them for the Romans.Seven branches of the sewer flow through the city streets and finally into the main road Maxim sewer.

Maxim Sewer, the most magnificent sewer in the ancient world
By 315 AD, there were more than 140 public toilets in Rome.The Romans who were good at communication developed public toilets into places for entertainment and leisure.Just like public bathrooms, people can gather in public toilets for a little money to engage in natural behaviors such as chatting with neighbors, planning parties, discussing politics, or contacting businesses.
laterEdalarianThe most magnificent sewer in the ancient world left to the Romans: the Cloaca Maxima.
In the 8th and 6th centuries B.C., the Etalians flourished in north central Italy, and the prosperity of Rome finally absorbed themImperium RomanuminAround the 6th century BC, the people of Edararia excavatedTiber RiverIts main trunk road was more than 16 feet wide, and later it was expanded for the Romans.Seven branches of the sewer flow through the city streets and finally into the main road Maxim sewer.When the storm comes, the sewers are cleaned by the great impulse of the flowing water.Pliny, a Roman scholar, called it "the most remarkable achievement" in Rome.It was still put into use in modern Rome 2500 years after its completion.
Ganzhou Centennial Sewer
As early as 900 years ago, a small city in southern ChinaGanzhouHowever, it has built a long underground dragon equal to the sewer in Paris. More importantly, the sewer today also bears the drainage function of 100000 people.
Ganzhou's ancient sewer is a gift buried 900 years ago by our ancestors of the Song Dynasty. It is not only owned by Ganzhou, but also by all Chinese.However, when today's people receive this gift, their faces inevitably flush.
This "political achievement" buried undergroundLiu YiHis merits and virtues have been publicized for 900 years.In the afternoon of June 14, the flood peaks of Zhangjiang and Gongjiang No.1 in Jiangxi passed through the urban area of Ganzhou within half an hour.Different from other flood areas in the south, the media described people in the old city of Ganzhou at that time as "living in order, children playing and fishing in the beach at the gate of the city, and traders doing business safely beside the surging flood.
Dredging method

Sewer pipe blockage is a common problem in daily life. Sewer dredging can be divided into several types: 1. The blockage caused by foreign matters accidentally falling into the newly installed pipeline or installation errors is generallydrain cleaner Directly dredge or replace the pipeline;2. Some pipelines will scale after being used for a period of time, which will make the inner diameter of the pipeline smaller and affect the normal drainage. This dredging must be done byHigh pressure water cleaningTo remove the dirt on the inner wall of the pipe and expand the inner diameter of the sewer pipe.Sewer dredging is widely used to dredge the vegetable washing pool, washbasin, bathtub, floor drain and toilet in restaurants, hotels and families.
Sanitary sewer dredging:
1、 Waterway dredger: It is the best product in the market.This product is particularly effective for unblocking clogging caused by hair, grease, paper, etc.Widely used in restaurants, hotels, families and so on, wash basins, bathtubs, floor drains, toilets plug dredge.Do not damage sewer pipes (including PVC pipes), and do not damage the electroplating layer.
Usage: Remove the accumulated water in the washing basin or sanitary ware, pour 50-100g of this product into the sewer. If there is no water in the sewer, please add half a cup of clean water.At this time, the pipe is boiling.After about 20 minutes, flush with plenty of water.
2、 The way to unblock the bathtub sewer: (mainly due to the hair left in the bath). Since there is a cover at the water outlet in the bathtub, it can only be unblocked from the floor drain. Go to the small shop to buy an 8 yuan hand cranked spiral steel wire (about 6 mm in diameter). Move downward from the floor drain while shaking until the hand feels foreign matter, and then gently pull up while shaking,The clogged hair and other dirt will spin on the spiral steel wire, and the problem can be solved easily. It is very convenient. If there is no cover at the water outlet in the bathtub, it is more convenient.(Never use hydrochloric acid. First, it pollutes the environment. Second, it is easy to cause danger to the human body. Third, if the pipeline is used for a long time, it is easy to be corroded by hydrochloric acid and perforated. This is even more troublesome.)
3、 Put the caustic soda into the mouth of the sewer, and then pour a pot of boiling water into it. It is not a warming pot, but a big pot for boiling water.
4、 If the workers were once invited to use iron sticks to pass through with acid, but the water was not drained later, it is not suitable to use iron sticks again, for fear that the corroded canal will be penetrated.You can use thick rattan instead. The rattan head can be nailed with ten eight inch long iron nails, which can be inserted and stirred at the same time to loosen the sundries, then poured with concentrated alkaline solution, and then pushed out the rattan. If it lasts for many times, it can be effective.In addition to rough rattan, you can also buy spring channel opener from the hardware shop, which has better effect.Salt, white vinegar and straw used by ordinary people can't work.
5、 Get some baking soda and vinegar.
6、 Other tricks
1. Animal grease blockage: If it is oil stain, it is recommended to use boiled water. Of course, it is better if you can buy concentrated sulfuric acid.If something is blocked, only the special tools for cleaning pipes can be used.
2. Cement plug: 70% hydrochloric acid can not be found, and 35% are sold everywhere, so you can try it.A little flour is added in it to act as a corrosion inhibitorUrotropinebest.It can reduce the corrosion of steel.
3. Go to the market and spend 10 yuan to buy a 2m long pieceSpring steel wireThe pipe dredging tool shall be bent 10-20 degrees at 1-2 cm above its head, dredged back and forth at the inlet and outlet of the sewer, and washed with water.
7、 Go to the mall to buy powder for professional cleaning of pipes, such as (swallowing Wang).
8、 If your sewer is made of new PVC material, you can first use a vacuum pump to suck the water off it, and then fill it with concentrated vinegar or caustic soda, industrial vinegar, and industrial soda, but don't mix them, just use one.If you don't know, or are not sure, or must be an old-fashioned iron pipe, you can only try it with vinegar grade weak acid at most.Never use the above methods.After filling these things, it will take about 3 hours to have an effect. If there is no response, you can only find a professional dredging team to force the dredging.
9、 Put in a small eel, or add some irritants such as washing powder or salt, and then cover the lid. The sewer pipe will pass in an instant!
10、 Green way to dredge the sewer: pour 1 cup of detergent into the blocked sewer, and then pour 3 cups of hot water.If this does not clear the sewer, pour another cup of vinegar into it.
11、 Log dredging sewer method: insert a log whose diameter is close to the inner diameter of the sewer pipe into the pipe, put a certain amount of water in the pool, and quickly pump the log up and down uninterruptedly. Under the action of suction and pressure, the blocked dirt in the pipe will be washed away.
Dredge the kitchen sewer
1. First of all, you should look at PVC or cast iron.Buy a 2m piece from the stallPipe dredgerMake some bends at 2cm of the head, put water into the dredger at the water outlet, shake it and put it in, then put water into the dredger at the water inlet, and repeat several times!At the same time, it should be dredged every other week in the future.
If professionals come, they can use manual methods first, do not pour water, or enclose the pool to prevent water splashing.Of course, other things should be put away.Also, you must ensure that you can get through in a short time, otherwise the smell will be very strong.
2. Find a professional unblocking company, they can certainly solve this problem.
3. Find an iron wire with a diameter of 0.5-1 mm, 3-4 meters long, fold it in half from the middle, and then twist it into a strand, then bend the two heads in different directions at the single end, and then stretch this end into the sewer pipe, grasp the other end, and tighten it in one direction while moving inward. If you can't twist it in case of resistance, pull it out. Don't tighten it at this time,If you pull it directly, some sundries can be picked up, and it can be basically unblocked after several times of repetition. If your iron wire cannot hook things, it is unblocked, then the problem may not be your home, and it may be that the downstairs pipeline is blocked.
4. The sewer is full of water. Press it down with a leather stopper and then lift it vigorously. This will create a certain pressure and pumping force, which may flush the blocked debris away;But if it is too tight, I'm afraid that only serpentine tubes can be used, and the iron wire mentioned above can also be used. However, this is expensive and difficult to handle. It's better to find someone to dredge it. In addition, there is another thing called pipe dredger, which is available in supermarkets, and you can also try it.
