The arrival of a large number of officials, Han Qi didn't care at first, in fact, when the court asked, he already had some ideas, the investigation is inevitable, he can't help this, although the investigation will have some problems, and even some impeachment, but he is not afraid, under the three major merits, he has enough confidence to face anyone, it's just trouble.

I thought that there were only a few, and when I was about to take them to visit after settling down these messengers, I found that it was really endless, 7 on the first day, 14 on the second day, and more on the third day.

The next day's visit, basically, was canceled, just kidding, Han Qi is the privy deputy envoy, a big man, you can't accompany such waves endlessly, wait for everyone to arrive, of course, most of the people can be together.

I waited for a total of 4 times in advance, and a total of 87 came, with different levels, there were eight or nine petty officials, and there were also four or five intermediate officials, and they gathered together, and the number was really quite a lot.

These officials, gathered together, still have some whispers, before the situation in Lingzhou, there is no intuitive view, this delay, in their opinion, may be a cover-up, but more and more people are coming, especially after the time is determined, there is nothing, just wait to visit, I really don't know, in such a short period of time, Lingzhou can build something.

After simple preparations, hundreds of carriages pulled them out of Xiping Mansion, Lingzhou now, there is not much of anything, that is, there are many horses, and the carriage is a little worse, fortunately, on the basis of the original ox cart, it has been modified, and it is not as complete as the original carriage, but it is also acceptable.

Fortunately, the place to go is not far, from Xiping Mansion, that is, thirty or forty miles, the carriage traveled for more than an hour, and it arrived.

When they got out of the car, they found that in the distance, they heard a huge sound of water, which seemed to be a certain river.

Is it the Yellow River, the largest river in the northwest is the Yellow River, among these officials, there are very few who are familiar with the terrain of the northwest, only a small number of people have been officials in the northwest, and those who know about the northwest side know that this is definitely not the Yellow River, and the Yellow River is still far away from Lingzhou.

There is the sound of water here, what does it mean, among these officials, there is another one, it is precisely in water conservancy, he even personally participated in the repair of farmland water conservancy in the north, thinking of such a large water flow, location, is it possible, there will be a lake here?

Just in the car, he couldn't see the outside, he subconsciously looked around, and was stunned, because there was a small hill in front of him, and he couldn't see what was behind the location of the water, but here, it was the core of the entire Xiping Mansion, the water conservancy hub, which means a large number of ditches.

That's right, there are really a lot of ditches, just on the side of Xiping Lake, there are 12 main ditches, and in the vicinity, with the convenience of the ditches, and a lot of contacts, what this official saw was the ditches like spider webs, distributed on this plain, and extended into the distance.

What a terrible project, this is the first idea of this official, he personally participated in the construction of water conservancy in the north, very clear, such a project, how difficult it is, if there is a central pond here, then, this project is really terrible.

When they walked around a small plateau to the place where the water sounded, they saw a different scene, a scene that shocked them.

At least 20 days have passed since the Weizhou Conference, and the project in Lingzhou has been open for at least 30 days, with the support of the Chamber of Commerce, huge materials have arrived, and the Liao State has also cooperated with the delivery of 200,000 slaves, which can be used to offset the value of 300,000 cattle, and can also be exchanged for some almost silk.

This figure is very unreasonable in the eyes of the Liao State, and it is not a woman, an adult man, where are these unstable factors, and a large amount of food has to be paid to feed it, which is just right for the Northern Song Dynasty.

This is the system is different, although the Northern Song Dynasty has not yet established a perfect industrial system, but at present, Lingzhou here, but a large number of manpower is needed, which has formed a large number of posts, which are completely useless in Western Xia.

The arrival of this part of the personnel has greatly supported the development of the Lingzhou project, although cattle and horses can replace manpower, it is on the farmland, and when the real project is real, someone must control these cattle and horses.

Millennial development, so that the means of arable land continue to change, the use of a variety of advanced ploughs, so that cattle and horses can play a role quickly, the most advanced horse-drawn plow, can even be 20 times faster than the ox plow, this does not mean that the horse is stronger than the ox, the strength, the ox is stronger, but in a certain project, it depends on how to use.

The arrival of these middle-aged men increased the number of people involved in this engineering in the entire Lingzhou to 450,000, more than 300,000 people of various livestock, and some of them, which were organized together with cattle and horses, especially the arrival of personnel from the Dinghai Navy.

Don't look at the only 500 people, but these 500 people, but they are experienced, many of them have been engaged in large-scale civil engineering for a long time, and have gone through the experience of the Dinghai Navy, when they left, they also specialized in the study of large-scale water conservancy projects, the excavation of canals and ponds, and the most suitable tools to bring.

For example, the hoist crane, the hoist crane used by the Dinghai Navy, is not simple, several hoist hoist cranes, must find a place to install, this is the treatment, after a special build and solidification, the formation of a complete machine, through fixation and labor-saving, at least seven or eight percent of the force can be saved, and the installation is convenient.

Take a pond as an example, if a pond is dug to less than 3 meters, it is impossible for manpower to use a shovel to bring up the dust and poplars, and it needs to be carried, traditional tools are not very suitable, several people dig the soil, and several people are required to transport, and even to a deeper point, more personnel are needed, which reduces labor efficiency to a certain extent.

However, every 20 meters, such a gourd crane is fixed, and the direction of force can be changed by saving effort and arranging some livestock, so that the place where only people can work can become animal work, which greatly increases efficiency.

Under the premise of juxtaposing five or six cows, or even more cattle, with the help of labor-saving, you can pull up 10 square or even 20 square meters of soil at one time, which greatly increases the excavation efficiency.

At present, the entire project has been started for about 50 days, but more than half of the project has been completed, especially near Pingxi Province, the largest pond, which is nearing completion.

In itself, when these officials first arrived, the project had not yet been completely completed, and it was being completed, and after a day or two, plus two days of water injection, it was like this.

This large tidal wetland composed of dozens of lakes adopts the method of flowering in the center, looking for a suitable place in the center, this place is one of the lowest places, excavating, about excavating a pond with an area of 500 square meters and a depth of about 20 meters, and then carefully introducing the water from other ponds into it, and then, after releasing the water, the whole excavation begins.

At least 15,000 people, 10,000 large livestock, and some technical personnel to help, this Lingzhou water conservancy project, the largest pond, later named Xiping Lake water conservancy project, a total of 50 days, excavation of more than 150 million cubic meters, plus topography and other aspects of the impact, as long as the water diversion project is completed, the cumulative water can be stored more than 280 million cubic meters, more than double the initial expectation.

More than double the water storage, which can be said to be terrible to the surrounding support, excavation of 150 million, but caused nearly double the effect, which is unimaginable for ordinary projects, this lake is not big, only about 19 square kilometers.

Natural lakes, rarely so deep, for example, Taihu Lake is considered to be a freshwater lake on the Chinese row, but its volume is only more than 5 billion cubic meters, not even 6 cubic kilometers, you know, the area of Taihu Lake, but more than 2,000 square kilometers, almost more than 100 times the current one, but the total amount of water, only less than 20 times, the reason is very simple, that is, because the depth of this lake is very large.

Correspondingly, Lake Baikal, the world's largest freshwater lake, with a volume of more than one-fifth of the earth's freshwater resources, can only rank 8th in the world in terms of area, but the amount of other water, including the Yangtze River and the Yellow River, is directly one-fifth of the total freshwater volume, the reason is deeper.

The average depth is more than 700 meters, and the deepest depth is more than 1,620 meters, which is the source of the volume of Lake Baikal.

Han Qi didn't know what Baikal Lake was, he just knew that more water could irrigate more grain, there was no shortage of information, and there was enough manpower, digging in situ was much better than ditching, anyway, it would be good to send people and dig brainlessly.

The same is true of Xiping Lake, from the very beginning, Han Qi built it quite deep, and under manual excavation, as long as there is enough manpower, the earthwork can be dug down, and then more water can be contained.

The average water depth of Taihu Lake is only 3.4 meters, here, the water depth of excavation is more than 20 meters, coupled with the relationship of low geographical location, the original horizontal position here is more than 10 meters lower than the surrounding area, compared with the Yellow River, it is much lower, compared with the water surface of the Yellow River, at least about 35 meters lower, so as to form enough water source.

Through the deep lake water storage, with the help of topography and various ditches, there are at least 4 ditches, connecting the Yellow River, and then through the sluice gate above the Yellow River, control, which is difficult for the Northern Song Dynasty in this era, but it is not impossible to carry out, as long as the opening of the Yellow River is a little smaller, and then more arrangements can be, these problems, the wisdom of the Chinese nation, has long been solved, now, 4 ditches at the same time water injection, at least 5 million cubic meters can be injected every day, to be completely injected, It will take at least 50 days.
