He was not particularly impressed by Zhuo Tianmin. He remembered that he had a son who once came to the executive committee to find Xiao Zishan and asked him to approve a note and give Wu Nanhai an egg for him - for his son to eat - eggs were in short supply at the moment.
There are only three or four items available every day, and they are usually only supplied to the sick.
He looked like he was in his mid-thirties, wearing training clothes stained with stone powder and mud. He pointed at the newly built pressure pool without looking at anyone and said: "...according to the design drawing: the floor of the water inlet chamber.
It was higher than the floor of the front room. Now it’s the same height.”
The people from the engineering team gathered around him and remained silent. Mei Wan was a little impatient: "It's just a few centimeters high or low. What's the big deal? If you cut out the design drawings for everything, it will be a rubbish project."
"That was a matter of lack of materials, so we had to resort to substitute measures. There was nothing we could do about it." Zhuo Tianmin became very angry when he heard what he said. "The cement, gravel, and yellow sand in this pressure pool are all used. Why don't you follow the drawings?"
Do?"
"The people in the engineering team didn't understand the drawings and didn't pay attention..." Bingfeng tried to smooth things over.
"This is even more unreasonable. The people doing the work are all novices, not professional workers. The responsibility does not lie with them. That's right. We all work in engineering and construction. How dare you say such a low-level mistake?" People around were whispering to each other.
.
Several professionals blushed, and Mei Wan couldn't refute him, so she had to say: "Then what do you think we should do?"
"Smash it and redo it according to the dimensions of the drawing."
"Not only is this a waste of materials, but it also delays the construction schedule!" Mei Wan almost jumped up, "Besides, you are not a hydropower professional. Do you know why there is such a difference between the front and back of the pool? What is on the drawing may not be correct, right?
There are many such things.”
"I really don't know, but just because we don't understand, we can't be vague about the drawings at all."
At this time, someone discovered Wang Luobin and said, "Commissioner Wang is here!"
When Zhuo Tianmin heard that Wang Luobin was coming, he turned around and saw that Wang Luobin was indeed standing in the crowd. He nodded politely to Wang Luobin and said nothing.
"Zhuo Gong, please continue talking."
"I've said all I have to say, and I really don't understand hydropower construction. Commissioner Wang, you make the decision." Zhuo Tianmin said coldly. He wanted to see how good the members of the executive committee were. Everyone's attention
All focused on Wang Luobin.
Wang Luobin walked around the pool and measured the depth of each part with a rod ruler. After checking, he asked Zhuo Tianmin for advice and said: "Zhuo Gong, what do you think should be done?"
Zhuo Tianmin said: "If the construction is not carried out according to the drawings, the quality is substandard. It is okay to cheat, but I am afraid that problems will occur in the future."
Wang Luobin turned around and asked Mei Wan: "What do you think?"
Mei Wan thought for a while and said: "It is indeed different from the drawings, but now there are few materials and we have to meet the deadline. I think I can make do with it! I will make changes later when conditions permit."
This proposal was approved by some members of the construction team.
Wang Luobin nodded and said: "If we rework it, we will waste some cement and steel bars, and it will also delay the time for power generation and grid connection, but we cannot make do with this matter."
He pointed to the pool: "The width and depth of the pressure forebay are larger than the channel. This is to slow down the flow rate of the water after entering the forebay, so that the sediment in the water will settle. This is the first step, the water inlet chamber.
It is higher than the bottom of the front chamber to prevent the settled sediment from rushing into the pressure water pipe and ensure the safe operation of the turbine."
Mei Wan knew that he had misunderstood the meaning of the executive committee again on this matter. His experience in building highways made him think that the executive committee mainly focused on the speed of the project, so this time he insisted on giving priority to progress. He saw the people in the construction team looking at each other with envy.
They all looked at him and waved their hands angrily:
"Stop looking at it, smash all the problematic areas and start over again!"
The construction team jumped out of the pool and hit the area to be reworked with an eight-pound hammer. The concrete blocks peeled off and fell. Wang Luobin felt distressed for a while. He didn't know when cement would be made. The long-range reconnaissance team was looking for various kinds of concrete.
The resources have just been sent out, and it has been almost a week now. Although there is radio contact every day, the resource exploration situation has not been reported yet...
Zhuo Tianmin stood aside and stared at Wang Luobin, as if he had just met Wang Luobin today. Usually his impression of these executive committee members is that they are kind and smooth. Xiao Zishan is a typical example. He will never say a word to make you unhappy, but you can't tell him apart.
Regarding his attitude towards a certain matter, even if he has to act as a decision-maker in some disputes, he will use a set of words to make everyone feel less embarrassed - he admires such people, but at the same time looks down on them, thinking that this is
Only those who do not have expertise themselves will find a way to survive.
Didn't he know that he had become Mei Wan's taboo after speaking several times in the construction engineering team, but he didn't care at all - didn't he bring his son here just to leave that hypocritical and empty living environment?
If he continues to do the same thing in another time and space, then why did he come?
The wind was very strong, and the trees with soft branches were swaying vigorously. The vegetation here in Bairentan was better maintained than in other places. The woods on the nearby rolling hills were dense, and waves of tree waves came with the wind. The wind suddenly became stronger.
, the weather also became gloomy, and it looked like it was going to rain. After the reworked parts were smashed, Mei Wan immediately reorganized his strength and personally led the engineering team to repair the concrete. Wang Luobin was also at the construction site.
Helping to clean up the debris, he thought as he worked. Just as Mr. Wen had talked to him in private, things in the group were not as simple as imagined. Judging from how he organized and arranged the construction these days, it was obvious that within the construction team
There are already cracks.
After the concrete was re-poured, the installation of the water turbine began immediately. The installation requirements of the water turbine are relatively high and the level must be measured. It is best to hoist it into place at one time. Mei Wan brought the steam crane and after an afternoon of tossing, the water turbine was finally hoisted into place.
Because there were no bricks or tiles available for the generator room, a shed was temporarily built as a cover.
The engineering team braved the drizzle to clean up the gravel and garbage on the construction site, installed the diversion canal gate, and finally completely excavated the earth and rocks at the water intake. The curved wooden gate played its role and the water did not flow in. Now it is time to wait for the concrete
It can generate electricity when completely dry.
This small hydropower station with a water head of 20 meters and a water flow of two cubic meters per second can provide the base with 200kw of electricity. The long-term plan for the future is to achieve a power generation power of 5 units of 1,000kw.
Because two generators are about to generate electricity at the same time, the original simple power supply model of pulling wires will have to change. Chang Kaien plans to build a new power grid system. The system is purchased in sets, and this power grid will use 110 kV high voltage.
For power transmission and consumption, industrial 380 volts and civil 220 volts are used. These are the voltage standards readily available in this time and space, and they also meet the power needs of various mechanical equipment brought by them.
Mei Wan originally planned to install all the power grid's transmission lines underground for safety reasons, but there were no suitable corrosion-resistant cable casings, so overhead transmission lines continued to be used on utility poles. Fortunately, the total length of the line from the hydropower area to the main urban area was only 100 meters.
, completely within sight. If necessary, a city wall can be used to connect the two areas, but it is not necessary yet.
With electricity, the next project is the water supply system. The water quality of the Wenlan River is mainly polluted by wastewater and waste from residential areas and farmland in the upstream counties. Therefore, the organic matter content is relatively high, there are more algae, and the sediment content is very small. For
For such water quality, it is not enough to rely solely on traditional sedimentation and disinfection methods. The algae will bring an unpleasant odor, and even the smell of chlorine cannot be masked. When the blue algae broke out in the Wuxi section of Taihu Lake, the water plant at that time
The water quality before leaving the factory is fully qualified in terms of physical and chemical standards, but the odor cannot be eliminated.
As a professional in water supply and drainage, Tian Jiujiu decided to use a percolation water intake after checking the hydrology and topography - the river water percolates through the soil along the river and then enters the reservoir. The water taken in this way is usually
It is not contaminated and does not require much processing.
The simplest mode is to dig percolation wells. However, Tian Jiujiu considered the large number of people to be supplied and the large water consumption in modern people's living habits. Therefore, he adopted a more complicated percolation gallery water supply system.
First, dig a water collection trench 15 meters along the river parallel to the river bank. The excavation depth of the water collection trench should be 1 meter below the lowest water level. The trench is made of multiple layers of sand, gravel and sand of different specifications.
A filter bed composed of small gravel, with a water collection pipe buried in the middle of the filter bed. In modern times, this kind of pipe is usually made of 50 to 100mm diameter perforated PVC plastic pipes. Tianjiujiu does not have such PVC plastic pipes, so concrete pipes are used.
, use a log with a diameter of 200mm as the inner mold, mix gravel, spun yarn and cement and cast it on site. This kind of pipe does not need to be too dense, but needs to be loose and porous, and the pipe joints do not need to be sealed - to facilitate entry
The groundwater in the water collection ditch can penetrate into the pipe. The entire pipe trench should be covered with soil with a thickness of not less than 30mm.
Finally, at the northern end of the pipe trench, at the lowest point of the terrain, a clear water well was built with concrete mortar and stones. The clear water that seeped into the water collection pipe was eventually flowed here to settle. The construction engineering team made a reinforced concrete cover for the well. After sedimentation
Clean water is pumped into the elevated water tower. The base of the water tower is built with stones and cement mortar. A ten-ton water tank removed from the ship is installed on it. The outside of the water tank is coated with a layer of cement for waterproofing and rust prevention.
Mortar. There is an ozone generator installed outside the water tower. This device uses high-frequency electronic devices to generate ozone for sterilization. The sterilization effect of ozone is no worse than that of chlorine, and it does not require complicated electrolysis devices and pipelines, and it does not cause great harm to the human body.
Before the electrolytic salt device was installed, this thing could last for a long time.
In order to prepare for typhoons, the entire high-tower water tank is firmly pulled diagonally on the ground with thick ship cables. The main water pipeline leading to the main city is made of PVC, because the construction team has not yet started the large-scale underground municipal sewer project.
A water pipeline was temporarily buried in a shallow trench.
