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 are in short supply at the moment. There are only three or four of them every day, and they are usually only supplied to the sick. [No pop-up novel website] i.bsp; 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 drawings: the floor of the water inlet chamber is higher than the floor of the front chamber. Now it is built to the same height."
The people from the engineering team surrounded 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 crappy 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 drawing dimensions."
"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 showed up at 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. It's up to you, Commissioner Wang, to decide." Zhuo Tianmin said coldly. He wanted to see how good the members of the executive committee were. Everyone's eyes were focused on Wang Luobin.
Wang Luobin walked around the pool and measured the depth of each part with a ruler. After the inspection, 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 not up to standard. 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 are available."
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 of connecting the electricity to the grid, 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 water flow 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. This ensures the safe operation of the turbine."
Mei Wan knew that he had misunderstood the meaning of the Executive Committee on this matter. His experience in building highways made him think that the Executive Committee mainly looked at the speed of the project, so this time he insisted on giving priority to progress. Seeing the people in the construction team looking at him with big eyes and small eyes, they 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 his attitude towards something, even in certain disputes. As a decision-maker, he will also use a set of words to make everyone feel less embarrassed - he admires such people very much, but at the same time looks down on them, thinking that this is a means of survival for people who have no professional skills.
Didn't he know that he had become a taboo for Mei Wan after a few words 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 is strong, and the trees with soft branches are swaying vigorously. The vegetation here in Bairentan is better maintained than in other places. The woods on the nearby rolling hills are dense, and waves of trees are blown by the wind. The wind suddenly became stronger and the weather became gloomier, and it looked like it was going to rain. After the reworked part was smashed, Mei Wan immediately reorganized his forces and personally led the engineering team to repair the work. The concrete pouring work had to be completed before the rain. Wang Luobin also helped clean up the debris at the construction site. He was thinking while working. Just as Mr. Wen talked to him in private, things in the group were not as simple as imagined. Judging from the progress he organized and arranged the construction these days, There are clearly cracks within the construction team.
Immediately after the concrete was re-poured, installation of the turbine began. The installation requirements of the hydraulic turbine are relatively high. To test the level, it is best to hoist it into place at one time. Mei Wan called in the steam crane and after an afternoon of tossing, the turbine was finally hoisted into place. Since there were no bricks or tiles available for the electrical machine 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 channel gate, and finally completely excavated the earth and rock at the water intake. The curved wooden gate has played its role, and water has not poured in. Now it is time to wait for the concrete to dry completely before electricity can be used.
This small hydropower station with a water head of 2o meters and a water flow of two cubic meters per second can provide 2ook of electricity to the base. The long-term plan for the future is to reach 1oook of electric power for 5 units.
Because two motors are about to be powered at the same time, the original simple power supply mode of pulling wires will have to change. Chang Kane plans to build a new power grid system. The system is purchased in complete sets. This power grid will use 110 kV high-voltage power transmission, and the electricity will be industrial 38o volts and civil 22o volts. These are the ready-made voltage standards in this time and space, and they are also in line with the various mechanical equipment they bring. electricity demand.
Mei Wan originally planned to install 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 telephone poles. Fortunately, the total length of the line from the hydropower area to the main urban area was only 1oo 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 now available, the next project was the water system. The water quality of Wenlan River is mainly polluted by wastewater and waste from residential areas and farmland in upstream counties. Therefore, the organic matter content is relatively high, there are many algae, and the sediment content is very small. 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 covered up. When the blue algae exploded in the Wuxi section of Taihu Lake, the tap water at that time The quality of the water leaving the factory fully meets the 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 obtained in this way is usually It is not contaminated and does not require much processing.
The simplest model is to dig a percolation well. However, Tian Jiujiu considered that the number of people to be supplied is large and the living habits of modern people also consume a lot of water. Therefore, a more complex percolation gallery water supply system is used.
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 generally made of 5o to 1oomm diameter perforated PVC plastic pipes. Tianjiujiu does not have such PVC plastic pipes, so concrete pipes are used. , using a 2oomm diameter log as the inner mold, mixing gravel, spun yarn and cement and then casting 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 - so that the groundwater entering the drainage ditch can penetrate into the pipe. The entire trench should be covered with soil of no less than 30mm thickness.
Finally, at the northern end of the pipe trench, at the lowest point of the land, a clean water well was built with concrete mortar and stone masonry. The clean water that seeped into the water collection pipe was eventually flowed here to settle. The construction crew built a reinforced concrete cover for the well. The precipitated clean water is pumped into the elevated water tower. The base of the water tower is built with stones and cement mortar, and 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 mortar for waterproofing and rust prevention. There is an ozone generator installed outside the water tower. This device uses high-frequency electronics to generate ozone for sterilization. The sterilization effect of ozone is no worse than that of chlorine, and it does not require complex electrolysis devices and pipelines, and it is not very harmful 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 to the ground with thick ship cables. The main water pipeline leading to the main city is made of PVC. Because the construction team's large-scale underground municipal trench project has not yet started, this water pipeline is temporarily buried in a shallow trench.
