Great Power Project

Chapter 411 Yu Qingyang is also depressed (seeking monthly ticket)

Pei Yanbing was so depressed in his heart, he thought, you don't play cards according to the routine?
"Mr. Yu, what you said is very real, and it is also a very realistic problem. I think Director Liu is also very troubled by this problem!

If you sprinkle some muck, it’s okay to clean up, but the stinky mud and black water spilled on the road, our sanitation workers may have to scold their mothers! Zhang Hua took the words and said with a smile.

"Mayor, what Mr. Yu mentioned is really not a small problem!
If during construction, the road is full of stinky mud and black water, our environmental sanitation bureau will really be helpless!

Ordinary people have to block our door? "Liu Qiyao from the Environmental Sanitation Bureau said with a bitter face.

"Mr. Yu, I think since you have brought it up, there must be a solution! Don't be a fool, just tell me!" Zhang Hua looked at Yu Qingyang and said with a smile.

"Now there is a kind of sludge removal and solidification equipment on the market!
Just slightly change the current construction process, transport the sludge to the water removal and solidification point through the pipeline, and then transport it to the designated storage point with the muck truck after water removal and solidification! "Yu Qingyang said very simply.

River dredging can be roughly divided into two categories, dredging with water and dredging without water.

Specific to the construction process, it is not complicated. Dredgers dig up the silt from the river bottom, some of which are transported to the beach through pipelines for filling, and some are transported by the dredger itself and transported to a designated location for storage.There is also a flatbed boat with an excavator on it to dig the silt directly from the river, and then load it on a boat that transports the silt and transport it away.

The advantage of this construction technique is that there is no need to cut off the flow, and there is no flood control pressure.The disadvantage is that because the silt is at the bottom of the river or lake, the construction technology that has been popularized at this stage cannot achieve the purpose of complete dredging.Of course, there are also human factors for incomplete dredging.

The other is dredging by cutting off the flow. After the cofferdam is cut off, the water in the cofferdam is drained, and then the silt is cleaned out with an excavator and transported away by truck. This is the construction technology adopted by the Municipal Water Conservancy Design Institute. .

There is also a process of cut-off dredging, which also requires drainage, but it does not need to drain all the water, just lower the water level, and then use high-pressure water guns, mud pumps and other equipment to suck up the silt. The principle of high-pressure flushing and suction is the same.However, this process cannot be used for urban river dredging due to site constraints.

The Municipal Water Conservancy Design Institute adopted the segmental dredging process with cut-off excavators, and there was a certain degree of selfishness, which Yu Qingyang did not point out.

Because no matter whether they use cutter suction dredgers or old-fashioned high-pressure suction dredgers, the enterprises affiliated to the Municipal Water Conservancy Bureau do not have these equipments, which means that the dredging construction of the old canal has nothing to do with them.You must know that there is a dredging department directly under the Water Resources Department in Jeju City. With fair competition, they will definitely not be able to compete with the Huanghuai Project dredging department that has boats, people and technology. This is absolutely intolerable to them.

Yu Qingyang knew their selfishness, but he didn't point it out. When working at the door of someone's house, he always had to leave something for them to eat. At the very least, he couldn't exclude them when designing, otherwise everyone's faces would be ugly.

The sludge solidification and water removal technology Yu Qingyang said is not complicated. It is to add a horizontal centrifugal dehydrator, use a high-pressure water gun or a high-pressure water knife to mix the sludge and river water at the bottom of the river, and then pump it up with a mud pump. The separation of the dehydrator separates the water in the mud and sends it back to the river. The water content of the sludge separated by the centrifugal dehydrator is much lower than that directly excavated by the excavator. At this time, the conveyor belt is used to directly It can be loaded and transported.

The cost is higher than directly digging with an excavator, but it can effectively avoid secondary pollution and damage to the urban environment.

"Mayor Zhang, all the leaders, you may feel that I am criticizing. In fact, I am more depressed than Mr. Liu and Mr. Bai just now! You know, the conditions or requirements I put forward are all to increase the construction cost!
Are you leaders of Jeju City considering giving us some financial compensation? "Yu Qingyang pretended to be depressed and complained to the leaders of Jeju City on the rostrum.

"Don't even think about it, our terms have been negotiated long ago, besides, we didn't make these demands!" Zhang Hua vetoed flatly.

"The mayor is right. Economic compensation is impossible. We are not a developed coastal city in Jeju City. We would like to spend five cents of our financial money!" Yang Yabin, deputy mayor of the Standing Committee, laughed.

"Yes! Mr. Yu, we can write a commendation letter to the Water Conservancy Department, and then give your company a pennant of a conscientious enterprise, and a plaque of a contract-honoring and trustworthy enterprise." Liang Yongchao, deputy secretary-general of the municipal party committee, also joked.

It was only then that the other leaders realized that although Yu Qingyang continued to pick faults and pick thorns, the final result was that their Huayu investment increased the construction cost, and the ultimate beneficiaries were their Jeju City. Thinking about it this way, everyone immediately got a lot more balanced. They all laughed too.

"Let me tell you, leaders, you have a very bad expression now. Jeju is the hometown of Confucius and Mencius. What about the humility and friendliness of the leaders? Is it really okay for you to look so good when you get cheap?" Yu Qingyang continued to smile wryly. complained.

"Hehe! Mr. Yu, don't worry, the people of Jeju City will never forget the help that Huayu Investment has given us in Jeju, and will not let the companies that help us develop suffer! All investments made by Huayu Investment in Jeju City will enjoy the best investment in the future. Preferential treatment!" Zhang Hua smiled and drew a cake for Yu Qingyang.

Yu Qingyang rolled his eyes and didn't speak.

Xindao, without you, who would invest in Jeju?Or without you, who would come to Jeju to make such a large-scale investment?

Of course this cannot be said.

"Director Pei, the solidified water removal equipment I just mentioned is widely used in southern cities. You can go and have a look! Centrifugal pumps for separating muddy water are much cheaper than buying dredgers!" Yu Qingyang pointed out Pei Yanbing.

The meaning is to tell Pei Yanbing, don't think that I don't know your little thoughts, just because I didn't point it out, doesn't mean I don't know.

Yu Qingyang did not continue to give comments on the design ideas of the Water Conservancy Design Institute. Although he wanted to propose the use of new materials and new slope protection techniques for river slope protection, but considering the construction cost, Yu Qingyang still endured it.

The restoration of the original sub-trough masonry retaining walls proposed by the Water Conservancy Design Institute is also possible, and most of the retaining walls are below the water level.

There are two levels of retaining walls in this section of the old canal city.

The sub-trough retaining wall is the retaining wall that is located on the river bed and is submerged or half-submerged by the river.

In addition, there is a secondary retaining wall, the retaining wall located on the second beach.

This Ertan does not refer to the Ertan Hydropower Station in western Sichuan Province.

Rather, it refers to the flat land exposed above the water level under the stable water level of the river course.

　One more!
　　The author is also depressed!
　　A friend's book is only ordered for 1000 yuan, and the monthly ticket of others is more than [-]. I am not as good as others!
