Tower Defense Strategy

December 2nd, Moon Palace.

After the completion of the second building, after three days of low pressure air tightness inspection, two days of normal pressure observation, and 12 hours of gas leakage test (high pressure), it passed the project acceptance and officially opened today.

With the help of a large group of robots, two strollers traveled back and forth between Building 1 and Building 2. It took a whole day to move.

Building No. 2 occupies a total area of ​​500 square meters, and the area of ​​the first floor is more than that of the expanded Building No. 1.

However, excluding the three-story hall, the usable area is still not particularly large.

In accordance with the housing needs of at least 50 people for emergency refuge at the industrial chain break, the conventional single room in Building No. 2 has an area of ​​12 square meters, and the couple’s shared double room has an area of ​​25 square meters.

It seems that the area is not much better than that of Building 1, but because of the structural design, the difference is very big.

Most of the structure of the second building is constructed in the concrete airtight workshop on the moon surface. Some materials are processed by the factory area, and the whole is not restricted by the diameter of the launch vehicle. The single storey is 3.8 meters high.

This high span is rather weird. It is neither the 3.3 meters common in commercial buildings, nor the 2.8 and 3 meters common in civil use. Its purpose is to use as few building materials as possible to strive for a better living environment.

All the houses are duplex. Single rooms are added up and down. Stairs, beds, immovable cabinets, tables and chairs are not counted. The movable area is 14 square meters. Between the two single rooms, there is a large cabinet facing the two rooms. , It will become a double room if it is dismantled.

When changing the double room, there are some movable changes in the stairs, the second floor partition wall and other parts. The second floor can be divided into an additional soundproof study room or childcare room according to the needs.

It is definitely not comparable to the living conditions of high-level talents on the surface, but the accommodation environment of the Moon Palace at this time is already the best in a bunch of space stations and bases, and there are no independent toilets elsewhere.

In addition to the increase in floor height, the future expansion plan of Building No. 2 will eventually change the "L" shape into a "T" shape. In this process, a room with a size one larger will be added.

Now the second and third floors of Building No. 2 are used for residential purposes. The first floor contains multifunctional meeting rooms, restaurants, recreation rooms, robot repair stations, gymnasiums, and a large room that is vacated as a kindergarten in the future. The central control center of the building is used for residential purposes. Lost in the negative layer.

The whole building does not yet have any experimental sites.

After the move, Building No. 1 was converted back to its original use, mainly used for indoor crop cultivation. The residence, restaurant, etc. will be demolished and used for later entry of part of the experimental equipment.

At this stage, the "Emergency Evacuation from Industrial Chain Break" has completed all the infrastructure preparations for the Moon Palace, and no more people will be introduced in the future. The reason is the same as that of the famous swimming pool that enters and releases water. The more people there are, the more people there are. Affect the speed of material hoarding.

The next shift to the stage of material hoarding and function expansion, the average daily workload of astronauts will be reduced by 40%.

Aerospace, like civil engineering and police, is a business where women are used as men and men are used as cattle. The reduction in workload is not a sudden conscience discovery by ground personnel, but only to give astronauts more leisure time and give stimulus strategies.

Humans’ adaptability to the space environment is zero. In a zero-gravity environment, even if they want to give birth, they can’t give birth to babies.

The moon's surface gravity is not great, and there are still many difficulties to overcome to give birth to a baby, but at least the possibility is no longer zero.

This is also the most important link in the sustainability goal. If there are no newborns in space, everything that has been done before will be in vain.

Taking advantage of the performance of the ground to provide support to space, after the completion of the first phase of infrastructure preparation, we quickly entered the stage of childbirth.

From this time on, two of the four couples in Yuegong have signed relevant research agreements. This is the main business, especially women, who entered the state of nutrition reserve and normalized physical examination as early as two weeks ago. Once they are confirmed to be pregnant, their The workload has to be further reduced.

Except for the two couples, those who have not signed a research agreement, regardless of whether they are single or not, have also lifted the restriction on childbirth. However, it is not recommended for a group to conceive a group of people until they have enough medical equipment.

Animals...male astronauts, the next job is to perfect all aspects of the Moon Palace base.

The lunar soil de-radiation device mentioned earlier is also at this stage.

In addition, there are three other construction projects.

One is the second phase of the second building, which includes the expansion of four to seven floors and the installation of equipment outside the building.

The second is the airtight corridor connecting Building No. 1 and Building 2. The project has a certain experimental nature, helping to explore the architectural interconnection mode of the moon surface city in the future.

Third, the square is leveled and a formal spacecraft take-off and landing zone is established.

In terms of engineering difficulty, the square leveling project is the most difficult.

It sounds strange, but the rules of physics determine the result.

One-sixth of the gravity of the moon's surface makes the soil ball leveling machine (dynamic compaction) very large here, and hitting the ground will cause a lot of harmful splashes.

During the construction of the second building, the foundation consolidation method used was grouting, but the simple action of grouting is also very troublesome on the moon. The temperature management must be very strict to prevent the slurry from boiling.

Putting it on the moon table, the temperature management requirements of grouting are even more difficult. Unless every place that needs to be compacted, a temporary "lid" with a certain degree of airtightness and heat insulation is built, otherwise it will not be achieved at all.

The ground is also using the information collected from the foundation construction of Building No. 2 to formulate a compaction plan and related machinery. Even if everything goes smoothly, it will take years to reach the Moon Palace.

Unlike the Moon Palace, the Kunpeng Space Station, which has lower orbital quality loss, welcomed the third group of members earlier.

The progress of Kunpeng Space Station in recent months has not been fast. The main reason is that the outer circle radius is too large, the designed cross-sectional area is also larger, the engineering volume is really large, and the simulated gravity when the outer circle rotates is greater, and most of the work does not stop rotating. Can't do it at all.

However, thanks to the joint efforts of astronauts, robots, and ground-based remote control equipment, the Kunpeng Space Station also achieved the first airtight closure of the outer circle at the end of November.

The first-stage gravity section has a width of five meters in the first stage; the second-stage has a width of seven meters and has two floors.

The first phase of the outer ring has a width of nine meters, a total of three floors, and a single-layer inner space height of 2.6 meters.

With a width of nine meters, excluding the corridor that is placed on the side to connect to the second phase of the project, there is still ample space.

At this time, the actual total internal area of ​​the Kunpeng Space Station (not counting the volume) is nearly four times larger than the two buildings of the Moon Palace combined, but it is a pity, because Kunpeng is a serious space station, and Kunpeng people want a separate bathroom, probably etc. Next life.

Aerospace toilets have passed through several generations of products.

When the first astronauts went to the sky, there were no toilets at all. Sometimes the launch was slightly delayed for several hours, and the astronauts had to cut off the power and urinate in the spacesuit.

Later, there was a urine bag, which is what the medical system uses for patients today.

Then, there is a decent toilet for pooping.

At this time, the toilet is still in line. First of all, the astronaut has to find a way to get the **** into a fist-sized toilet in a zero-gravity environment (it is a very technical challenge, for which a plastic bag with finger cots appeared). Then put the lid on and row directly into space!

The moment the toilet was connected to the vacuum, the scene, I don't know...you can still see it.

Then there will be high-end goods on the market. The suction sanitation system contains both pee and poop. They generate a certain amount of suction by pumping air, so that they will not float everywhere. After they are collected, they are packaged and thrown into the atmosphere.

It was only later that the space toilet, which is connected with the water cycle as we know it today, gradually evolved. The final metabolic product after dehydration is a package, which looks like a vacuum nut packaging.

However, this set of toilets connected to the water circulation device is a bit large. All the equipment of the Kunpeng Space Station must come from the surface. It is impossible for everyone to have one set.

Some students must ask back, isn’t the Kunpeng space station rotating to simulate gravity? Can’t concentrate sewage treatment like normal toilets?

The answer is...really not.

The corrosion performance of sewage is obviously higher than that of ordinary things. If the drainage pipe surrounding the entire space station is used, once it leaks, it will inevitably be a very serious accident.

At this time, human beings have no experience in building a rotating space station, and there is no data to guarantee that man-made sewage pipes will not cause problems in the space environment for decades.

Another point is that the Kunpeng Space Station needs to be shut down occasionally for maintenance, and no one can ensure that all people on the station can hold it, which eliminates the possibility of using conventional toilets.

In order to control the scale of the disaster in the event of any disaster, and the space station members can complete emergency treatment autonomously, toilets must be centrally installed, the pipeline system must be isolated from other power and signal cables, and even the gas management system must have a separate emergency plan. ~www.wuxiaspot.com~ There are only three general sanitary areas in the outer circle of Kunpeng Space Station, which correspond to three sections cut out of three structural columns. Each floor is in the same position. If you just come to the outer circle, you must go to the toilet. Run more than a hundred meters.

There are also three sanitary areas.

Two of them are reserved for exclusive use by the hospital and are located on the outermost layer of the three-story structure in the outer ring, which is the first floor of the human body. One is scheduled for a possible future livestock system. This is not yet certain, but the gas and liquid pipelines and processing devices have been arranged (no toilets are installed).

Don't talk about the toilet.

After passing the first airtight inspection of the outer ring of the space station, a third group of people arrived. These people will be responsible for the construction of the inner room of the outer ring in the next few months. The relevant boards are inside and there is no need to enter or exit.

By the way, after this structure is airtight, it is troublesome to get in and out of things with larger length and width values. It needs to be stopped as a whole. A specially set up large airtight room is used to open it to the outside world, and then a spacecraft is suspended aside to stuff things in.

In the future, it is possible to build a device for grabbing a cargo spacecraft while it is rotating, but it is too difficult and the risk is too high. It hasn't been made yet, so it can only be used by ordinary robotic arms.
