Volume 1 Chapter 585 On the Necessity of Public Facilities Construction

Previous page        Return to Catalog        Next page

    Throughout China, many modern cities have a bright appearance, but only a heavy rain can reveal their true colors.  Only the old city of Qingdao has never been flooded.  It was because of the German invaders that the sanitary conditions in Qingdao were very poor at that time. There were no above-ground water pipes, let alone sewers.  When the German troops first arrived, they were not accustomed to the local environment and often suffered from enteritis.  Germans believe that the epidemic of E. coli and dysentery may be caused by the following two reasons: soil and drinking water pollution, and crowded living environment.  It was at this time that the Germans decided that the sewers were of strategic importance to them.  According to the lease treaty with the Qing government, Germany occupied Qingdao for ninety-nine years.  Therefore, the Germans laid sewer pipes completely according to the design standards that have been used for a hundred years.  All of this made me feel deeply. Living in the modern society of the 21st century, living in a world with a severe shortage of sewers, sewage often flows freely, and even the water from septic tanks can overflow onto the streets and smell bad.  In the city, people eat vegetables fried in gutter oil, drink drinks with preservatives, stew sulfur-smoked Tremella and lotus seed soup, and watch the neighbor's children happily drink Sanlu milk powder.  Smelling the indistinguishable haze in the air, I envied in my heart the haze in Beijing, Shanghai, Shenzhen and Guangzhou that could be called famous and tasted like petty bourgeoisie seasoning or mutton-boiled meat, which was stronger than the earthy smell here.  too much.  Being born and raised in that era, I have become numb. The most I can do is roar on the Internet and vent my dissatisfaction. But it is different now. I have come to this pollution-free and chemical-free synthetic product. There are no preservatives and no children.  A time when you need to be force-fed milk powder mixed with all kinds of weird things.  ¡°And I am still an emperor, why don¡¯t I do something that is beneficial to the people and the survival and reproduction of the Chinese nation?  Therefore, I naturally have to make changes, and I have already started making changes as early as when I was in Hancheng County.  It can be said that Hancheng County is the area with the most complete public facilities in the entire land of China.  Not only are there public toilets and bathrooms, but there are also public squares where people can rest and chat and children can play. There is also the affordable and reasonable Quanjude Grand Theater of Hancheng County. Moreover, the newly built Hancheng County has no city walls.  In the county town, there are huge drainage pipes under the streets that three people can walk upright and side by side. After being filtered by a physical sewage treatment center, the filtered domestic sewage is discharged into the Yellow River.  Well, there is nothing we can do about it. In fact, it is just a few huge pools, much larger than the game pool, which are specially designed to block all kinds of debris and settle sediment.  No way, this is all I can do.  I don¡¯t understand how to build a sewage treatment plant. After all, in the 21st century, neither my county, city nor even large enterprises have seen such a thing. Moreover, all their industrial water is discharged directly into rivers and ditches, which is environmentally friendly.  The department is like a group of roly-poly people. Apart from having smiles on their faces, I don¡¯t know what they are doing.  It was later, when it was said that the industrial pollution in the county was to be inspected, and we went to supervise and inspect it, that we saw something like this, that is, several large ponds. The sewage flowed from one pond into another pond, and then flowed into another pond.  , and finally discharged into the ditch.  Of course, in the 21st century, physical methods for treating industrial sewage include microporous filters, centrifuges, electric water pumps, etc.  We don't have that. We can only rely on the high and low staggered heights of the pool to make the wastewater flow and block the wastewater with grilles and screens, and then let it slowly settle and settle on its own.  Anyway, those seven oversized pools can just let it slowly settle and then flow into the Yellow River.  But at least the septic tank contains the most polluting things and turns them into excellent organic fertilizers, which is definitely a major innovation of this era.  Ancient China also had a drainage system, and it was quite complete in big cities.  The ancients always paid attention to the construction of sewers during urban construction.  Sewers first existed in the palaces of the Yin and Zhou dynasties. By the Han, Wei and Six Dynasties, major cities were generally equipped with them, and sometimes pottery pipes were even used as sewer pipes, which were very standardized.  Anyway, I remember seeing information on the Internet, saying that someone once visited the ancient city of Ganzhou, Jiangxi Province, which is a miracle in the history of world urban construction that has survived to this day: the urban drainage system "Fushou Ditch" built in more than 900 AD.  Compared with the waterlogging everywhere today, we can even admire the wisdom of our ancestors.  Fushougou is the drainage system of the ancient city of Ganzhou built by Liu Yi, an ancient water conservancy expert, who was in charge of the construction of Qianzhou (Ganzhou was called Zhouzhou in ancient times) from 1068 to 1077 during the Xining period of the Northern Song Dynasty. The entire system is divided into two major parts: Fugou and Shougou.  The total length of the main ditch is nearly 13 kilometers, with a total of six outlets, three of which drain into the Zhangjiang River and three into the Gongjiang River. The Fushou ditch is still intact and smooth, and it is still the main channel for daily sewage discharge by Ganzhou residents.  Ancient brick ditch wall and stone cover structure. At that time, Liu Yi used a combination of open ditches and culverts according to the topography of Ganzhou City to connect with the urban ponds, and then discharged wastewater into the city through two water windows under the city wall.  , Gongliang River. This drainage system formed the "side branches and horizontal network", "vertical and horizontal lines, well-organized", clear primary and secondary, and combined drainage and storage in ancient Ganzhou City.Network has played an important role in improving urban environmental sanitation and living conditions.  This system also forms a large-capacity reservoir in the drainage network to regulate the flow of heavy rains and reduce sewer overflows. The sewage can also be used to raise fish and grow vegetables. It is the earliest comprehensive sewage utilization project in the history of urban construction in Ganzhou City.  What does it mean to be a descendant?  Just look at Fushou Valley.  Today's urban drainage system is definitely not something that can be used by future generations. It would be a big deal if it doesn't give future generations a slap in the face. ???????????????????????????????????????????????????????????????????????????? The original one in Chang¡¯an was to dig deep ditches along the streets. However, this kind of drainage system can only cope with small scenes. I don¡¯t want the city to be wiped out when it rains heavily in Chang¡¯an, so I decided to rebuild it according to the original plan.  Now Chang'an's drainage system has been under construction for nearly a year, and most of the underground systems have only been completed less than one-third. There is no way, I want to make it a large-scale one based on the one-hundred-year service life limit.  Drainage system.  Moreover, all drainage systems are dug underground according to the direction of the road. The shallowest drainage channel is less than ten meters, and the main drainage system at Zhuquemen is as deep as forty meters. Fortunately, there is cement  , with steel bars, and countless unknown refugees who are willing to work as long as they have food to eat, this young master can have such ambitions.  The drainage system of Chang'an City alone has nearly 35,000 workers working silently underground. You must know that only 100,000 people built Chang'an City, and it took less than nine months.  The entire city of Chang'an has been roughly built, and it took me a year to build only one-third of the drainage system.  However, the money spent is really not that much. Anyway, the cement, steel, and other materials are produced by my own family. In addition, I have donated my grain store and all the grain to the country. Therefore, in the court,  Although the Minister of Civil and Military Affairs was a little bit concerned about building such a costly drainage system, he did not stop me in the end.  The important thing is that there are too many refugees. We must find something to do for them. Otherwise, we cannot keep them in vain. How can we do that?  So with the ministers pinching their noses and acquiescing, I recruited a large number of refugees to work on this infrastructure project.  The people who take care of food still have a small salary. There are too many refugees, and we have no choice but to find something to do for them. Therefore, road construction and various construction projects have almost wiped out all the refugees.  Although there are still many new refugees, it doesn¡¯t matter. There are still things waiting for them anyway.  It is believed that Chang'an City's overall drainage system will be put into use by the turn of next spring and summer at most.  Domestic sewage, rainwater, etc. will be directed to Chang'an's sewer system. After passing through this system, they will be discharged into the physical water treatment center on the edge of the Yellow River.  Entering the underground pipes of the drainage system, high, in one word, is really high. Anyway, Li Xuanba next to me was stunned for a long time before he said this, which made me think that this guy was praising me for being wise and powerful, but he ended up doing it.  For a long time, he praised the sewer as being tall and wide.  "What's the matter, brother-in-law? Don't you think this place is too big?" Li Xuanba couldn't help but ask when he saw my young master looking unhappy.  "Don't even think about it. Today's Chang'an has a population of over one million people every day. Moreover, the city is so huge that no one knows how much domestic sewage is discharged into the Wei River every day. Moreover, the terrain here is flat and  "Hey, what if a strong storm comes and people are drowned? Without such a large drainage system, can all the wastewater in this big city of more than 160 square miles be drained out?" I glared at this guy and said.  .  "Yes, it seems that I was wrong." Li Xuanba smiled a few times and continued to admire the huge drainage system on the main road. This is just under Zhuque Street. There are no buildings on it, so it becomes  It is the main road that collects the sewage from all the cities and towns in Chang'an City.  "Eight meters wide and four and a half meters high. Then, starting from the north end of Zhuque Street, such a large pool is used to settle urban sewage. In this way, it can greatly reduce the pollution brought by urban sewage to the Wei River. You know  "Is that so?" I said proudly.  "At that time, we will hire a group of workers to clean the sedimentation tanks in the sewers on time to ensure the clean water quality of the Weihe River." After all, people in this era rely on these natural water sources for production and living water, and the water is not clean.  , people get sick easily.  Although public health has been vigorously promoted under my administration in the past few years, it cannot cover all areas. We can only work hard and do our best.  Public health cannot be ignored. If you don't pay attention, when a plague comes, you really don't know how many people will die and how many families will be destroyed.  This is why I want to vigorously build various infrastructures.
