Chapter 64 Water Tank
The humid air mixed with the scent of earth and grass came in bursts from under the door, as if the increasingly hot May had returned to the spring days.
The rain gradually stopped.
Chen Mu took Wei Dalei, He Ying, and Tang Jing out from under the door to conduct an on-site inspection of the water diversion project that was about to be built.
Others remained in the house because of their limited ability to protect themselves.
"Considering the limitations of Chen Mu's current ability, my idea is to use this rainwater riser to divert the water." Tang Jing said, pointing to
a white rainwater pipe hanging vertically on the outer wall of the storage room.
The so-called rainwater riser, commonly known as rainwater downpipe, is a pipe installed on the exterior wall of a building to drain rainwater from the roof.
"Catch all the water drained from it and divert it indoors?" He Ying asked.
"Of course not." Tang Jing smiled: "We can't control the amount of water at all, and if we collect water at the bottom, the height may not be enough." "Height
?"
"If you want to divert water when there is no power equipment like a water pump, , we can only rely on gravity, but the problem is that we not only have to bring in the water, but also have to drain it out. Therefore, it is difficult to achieve without a certain height difference." "Okay, but I still don't know the specifics
. How to achieve it?"
"The general idea is that I plan to drill a hole in this rainwater pipe, and then connect a pipe. After this pipe enters the room, it will go around in a circle and then be connected to the outside. "Then, introduce in this
pipe There is an opening on the indoor pipe, and another water pipe comes out for our use. The reason for this is because once it rains, the amount of water in the original rainwater pipe will be beyond our control, so a transitional means is needed. Chen
Mu thought for a moment and asked: "If we open an opening in the vertical downspout, if it rains lightly and the water volume is not large enough, can we receive the water?" Tang
Jing nodded: "Yes, it is almost impossible for the water in the standpipe to undergo free fall. Instead, it will flow downward in a spiral along the pipe wall, so this is not a problem."
He Ying asked again: "But if this is the case, don't we only have water when it rains? "
Tang Jing smiled and said: "So, we still need to build a reservoir. " "
Reservoir..."
"It's not just a reservoir. Because the water is collected on the roof and drained down, there will definitely be a lot of impurities. Therefore, some simple treatment is needed." "
"for example? "
For example, rainwater cannot be used for the first ten minutes and is allowed to drain away. In addition, I will add a grille and sedimentation tank at the front of the reservoir." "
When everyone heard these words,
they suddenly felt unreal.
"Don't be afraid, although it sounds complicated, it is not that troublesome. The thick and thin grilles in real water treatment are mostly used for sewage treatment. They are two sets of large equipment. It is used to ensure that the quality of the water entering the water pump will not affect the operation of the equipment, but now we only need to do a simple filtration with a filtration accuracy of less than 0.1mm. In addition, the length of the sedimentation tank does not need to meet the specification requirements. Drinking The water adds an extra step of precipitation before boiling. As for the method of boiling water..."
"Stop! "
Everyone said in unison, interrupting Tang Jing's speech.
"Good guy, do you think we can understand or something? "Wei Dalei felt his head buzzing.
Chen Mu roughly understood what he meant, but what he heard about the thick grille, sedimentation tank, etc. was confused.
He Ying said distressedly: "Tang Jing, tell the truth, you Didn’t we spend all our sleeping time studying in the past? Moreover, these things have never been taught in school. "
Tang Jing was a little embarrassed, and said with a smile: "Then let me make it simple?
"Needless to say, we will do whatever you want us to do when the time comes. " "
Chen Mu was also a little helpless, but after all, he was a little faster than Wei Dalei and He Ying. He immediately thought of a question:
"How big should the reservoir be? "
Tang Jing said: "I have calculated this. According to the per capita water consumption of residents in the shopping mall, the daily domestic water consumption per person is 120 to 180 liters, which includes drinking, bathing, washing clothes, flushing toilets, etc. Let's take a If we calculate it based on 200 liters, then it is 0.2ml per person per day.
"We are now 12 people, but we always have to consider development. If we calculate it as 50 people, one day is 10ml. Based on the rainfall frequency and return period of the mall in the past 20 years, I recommend storing 30 days of water consumption. Calculate it like this , that is 300ml."
"How much is 300ml?" Wei Dalei asked.
"It's probably just a bottle of mineral water in a small bottle."
"It seems okay."
"The reservoir must be closed to prevent evaporation. It should only be opened when water is supplied and drained, but there will still be losses during use. Considering various margins, I suggest building a water storage tank with an effective volume of 400ml. The actual volume will be approximately 650ml. The specific dimensions are 8cm long and 10cm high." Tang Jing finished
.
The scene fell into silence again.
Everyone was mentally estimating what such a water tank would look like.
Chen Mu had been accustomed to Tang Jing's erudition for a long time, but at this time he still felt a bit illusory. He had thought of certain possibilities and wanted to ask several times, but was unable to ask.
After hesitating for a while, he finally held back.
Then he asked, "Since the plan is so clear, shall we start construction immediately?"
"So soon?" Wei Dalei was stunned.
"Such a big project will probably take a long time," He Ying said.
"Well, the most important thing is to see what level of abilities Chen Mu and Dalei have reached now." Tang Jing said this and then asked: "Chen Mu, pipes should be no problem for you."
" Almost."
Chen Mu thought for a moment and said, "And maybe the thicker the pipe, the easier it will be." "
That doesn't matter much. In water pipe decoration, the most difficult thing is the connection between pipes, fittings, etc. If it is a plastic pipe, it is actually difficult to achieve a seamless connection without hot melt conditions, but this aspect is not a problem for you. Therefore, the accuracy of the pipe itself is not high, as long as it does not leak. "
" I'll do my best."
"As for the water tank, I don't think it's a big problem. In fact, it's just an enlarged version of the room. It's even easier in terms of details. At least it doesn't need a door." "But, 10 centimeters high
. The water tank is still a bit difficult for us now." "
Well, I will think of a way to do this, but if it doesn't work, I may need to build a simple scaffolding."
When Tang Jing said this, everyone looked at her with frightened expressions. He looked at her and said with a smile: "It's only 10 centimeters. You can't kill anyone if you fall. Don't imagine that it's 10 meters before. It's two different things."
Everyone gradually felt relieved when they thought about the issue of falling from heights that had been discussed many times.
"In this case, let's do it sooner rather than later."
Chen Mu stretched out his hands that had been in his trouser pockets.
If you can really build such a project with your own hands.
It seems to be quite a sense of accomplishment.
