Eighth year of Chongzhen

Chapter 820 People's Livelihood Project
While water conservancy construction in various parts of Daming is in full swing, following Zhu Youjian's instructions, urban governance in various prefectures and counties is also in full swing.

Zhu Youjian was deeply impressed by the scenes of waterlogging in various degrees in many cities during the rainy season in later generations. He was also deeply saddened by the huge losses of urban residents and property caused by continuous heavy rainfall. Now that the world has If you want to control the power of the world, you should make changes within your ability.

Although he knows nothing about how to prevent urban flooding, this does not prevent him from being able to come up with corresponding countermeasures.

Therefore, in the 20th year of Chongzhen, the cabinet wrote the world according to his instructions, requiring all local governments to report the plans and measures to effectively prevent waterlogging in their locations. .

Within half a year after the cabinet document was issued, various plans and measures were reported to the capital one after another by local governments. Sun Chuanting and other cabinet members convened the ministers of the Ministry of Industry and professionals from the Ministry of Industry. After careful screening and discussion, several sets of plans were selected. Enter the palace and present it to the imperial court for Zhu Yujian to decide.

The monarchs and ministers had a special discussion on this matter in Zhaoren Hall.

In the document formed by the cabinet, the causes of waterlogging were first listed one by one. The reasons are roughly as follows.

First, cities that often suffer from waterlogging are built in low-lying land and flood detention areas. Because the terrain is too low, whenever the local heavy rains continue, the flood water flows to the ground, so the city is easily flooded.

On the contrary, areas with relatively high terrain are not prone to waterlogging.

For example, although the old cities such as Suzhou and Wuxi are water towns, because the old cities are located in areas with relatively high terrain, it is not easy to form stagnant water.

Secondly, the drainage system is not perfect, and too few drainage stone channels, dry ditches, and drainage holes are built, or they are blocked and silted due to lack of professional regular maintenance, resulting in the inability to quickly discharge the accumulated water.

Thirdly, the vegetation in the city is sparse, and there are few or no ponds at all, which cannot store a large amount of rainwater, thus forming a large area of ​​water due to the phenomenon of "water catchment".

When the cabinet was summarizing the relevant local measures reported by the governments of various places, it became very interested in the situation reported by the Guangzhou government and the Ganzhou government. The planning of the city has been fully studied, and it is ready to be used as a reference in the formulation of the overall plan for urban waterlogging prevention.

According to the situation reported by the Guangzhou and Ganzhou governments, and from the local chronicles, there has never been a large-scale waterlogging in the two cities for hundreds of years, all of which benefited from the related facilities built in the former Song Dynasty.

For example, in Guangzhou, in order to effectively prevent urban waterlogging, several generations of chief officials have worked hard on it. After more than ten years, the relevant facilities have finally been repaired. inconvenience and loss.

These drainage facilities and supporting projects are mainly composed of two aspects.

One is to build two cities in the east and the west, and the other is to excavate six large canals for drainage, flood control, fire prevention and navigation, namely "Liumai Canal".

In particular, the ingenious connection between the Liumai Canal and the moat has fundamentally eliminated most of the hidden dangers of waterlogging.

In the rainy season, the rainwater and sewage in the city flow into the six main canals from the small ditches in the streets, and then discharge into the rivers.

Ganzhou, which is located in a place with abundant rainfall, has completely bid farewell to the problem of flooding in the city because of a "Fushougou".

Fushougou comprehensively integrates the functions of urban sewage discharge, rainwater drainage, river and lake adjustment, pond connection, air humidity adjustment, etc., and even forms an ecological and environmental protection cycle chain in which fish are raised in ponds and silt is used as organic fertilizer to grow vegetables. The entire drainage network " Fold vertically and horizontally, or lie down or see."

Liu Yi, the magistrate of Ganzhou in the Northern Song Dynasty who presided over the construction of "Fushougou", has long passed away, but the temple built by Ganzhou people to commemorate this virtuous official is still there. It has stood for hundreds of years.

In the treatment plan given by the cabinet, in addition to requiring that the drainage ditches inside and outside the city should be interconnected with the moat, the floor tiles laid in the city should be waterproof, and there should be appropriate gaps between the bricks and stones to facilitate the penetration of rainwater. Zhu Youjian was amazed by the requirement to plant green grass, reeds and other green plants all over the depressions.

Isn't this the embryonic form of wetland parks that commonly exist in various places in later generations?

The wisdom and foresight of the ancients really opened his eyes and made him feel extremely admired.

Originally, he intended to renovate Daming City by imitating the measures and methods used by European cities such as Paris, London, and Munich to deal with waterlogging. However, due to technical limitations, this kind of transformation is temporarily unfeasible.

The plan proposed by the cabinet is the most in line with the current actual situation. In the foreseeable future, before the second industrial revolution, this plan that fully considers the use of nature's own functions to effectively resolve floods is the best. It is also the most environmentally friendly.

Waterways are the conscience of a city, and the construction of urban drainage systems concerns tens of millions of people, so we must not be short-sighted. Sun Chuanting and others know how to learn from the ancients and supplement and improve them according to the current situation. The ability of people to govern is still very strong.

After putting forward his own opinions on some details, Zhu Youjian approved the overall plan for the control of urban waterlogging in the Ming Dynasty. After the inspection, the budget and construction time were taken out, and then reported to the capital for review by the cabinet, the Ministry of Households, and the Ministry of Industry, and then the money was transferred to various places.

This huge urban renovation plan has been implemented in the second half of the 20th year of Chongzhen. The first start is in many cities in the south. Since most parts of the north are still in a semi-arid period, the urban renovation project in Jiangbei will start later.

The overall completion of this project will take about ten years. According to the budget plan made by the Ministry of Households, it will cost about 500 million silver coins. The number of hired workers cannot be counted for the time being, but it should not be less than 10.

Ten years, 500 million silver coins, and an annual expenditure of 150 million. This amount of money is nothing compared to the various benefits generated after the completion of the project. People's livelihood projects should not only be based on the investment at that time, but all court officials with a certain vision will see its strategic value.

While the two major projects of water conservancy and waterlogging have been started one after another, the work of widening and hardening the official roads has not stopped.
