"In addition to the new population, we cannot relax the regulation of the existing demographic structure.

Development is important, but how to achieve more stable development is something that your SASAC must consider.

Therefore, when absorbing the foreign population, the Ministry of State-owned Assets Supervision and Administration should consciously carry out 'peak shaving and valley filling' of the population structure, and use different policies to guide the integration of people of different ages.

Only by doing our best to control the fluctuations of the young population under the age of 30 within the range of no more than 10 percent above and below the standard line will it be possible for us in China to establish the most reasonable society in 50 years. ”

Wu Guangliang casually set the future family planning policy of Huaxia with Xiaobao, and then paid attention to the comments on the online platform about his proposed task, because this was the main purpose of his return to Huaxia.

"Since we can't use our current elevator under such conditions, we can only change the shape of the elevator.

The elevator had to be able to avoid the lower stairwells and be able to carry people directly from the ground to the upper floors. ”

"Yes, this kind of elevator can not take into account the different needs of upstairs and downstairs, we can only redesign a safe and effective elevator."

Anyway, Huaxia's online platform is almost completely open, and all members can speak freely, whatever comes to mind.

As long as their ideas are supported by more people, the SASAC will determine what they deserve based on the proportion of their ideas in all useful ideas and the approval rating of everyone.

"What do you think of the watermill by the river?"

"Waterwheel?"

"Aren't we talking about elevators? What's the matter with that waterwheel? ”

"Don't you think the way the watermill runs is in line with what we're talking about?"

"You mean to design the elevator to look like a waterwheel?"

"If we made a seven-story wheel out of steel like a waterwheel, and then we replaced those baffles with movable hanging baskets.

As long as we turn this big wheel with gears and motors, we can send the people in the gondola to any floor.

Moreover, since the wheels are round, it is possible to avoid the stairwells on the first and second floors without any impact on the residents on the first and second floors. ”

"However, although this design can avoid blocking the first and second floors, it is also due to the existence of this arc, the stairwells on the sixth and seventh floors are also far away from the hanging baskets of the wheels, how can the people in the hanging baskets safely enter the stairwells on the sixth and seventh floors?"

"We can install some aisles on both sides of the wheels, and the people in the gondolas go into the aisles on the different floors first, and then through the aisles into the stairwells."

"The wheels are moving, but the aisles are fixed, and how do you design them to hang over the hallway out of thin air?"

"Why do we have these aisles hanging over the hallway?

There are no safety hazards in the aisles, so there is no problem in repairing them directly from the ground.

This problem can be solved by using reinforced concrete columns as the stress point on one side of the aisle, and placing the stress point on the other side of the aisle on the stairway. ”

"The seven-story wheel, the top floor of the hanging basket and the aisle are almost at the highest point of the wheel.

In other words, the farthest part of the aisle must be set above the center of the wheel, which is equivalent to the length of the aisle not less than the radius of the wheel.

Seven-story buildings are generally more than 20 meters long, which means that this aisle should be at least 10 meters long.

With such a long span, the two stress points may be a bit overhanging.

I think at least three concrete shelves should be used to withstand the aisle above to ensure the stability of the aisle. ”

"In fact, the length of the aisle on the sixth and seventh floors is the longest, and the aisle on the third, fourth and fifth floors in the middle will not exceed five meters.

Even if you leave more space for movement, the length of the aisles on these floors can be controlled within six meters.

So we could have poured one concrete shelf six meters from the stairwell, and then another concrete shelf close to the stairwell, and then set up aisles on both shelves.

All we need to solve now is the problem of building a six- or seven-story aisle.

According to the mechanics we have mastered, we can build an oblique support column from the shelves of the fifth floor aisle, and form a stable triangle of the sixth and seventh floor aisles, concrete shelves and support columns.

In this way, the gravity of the sixth- and seventh-floor corridors is transmitted through the support columns to the concrete shelves below, and the construction cost of the five-story corridor can be reduced by at least half. ”

"This method is good, but there is still a problem to be solved, when the wheel is turning, it should not be able to get on and off people, because there are certain safety hazards in and out of the gondola during the movement.

Therefore, the hanging basket chooses to go to several floors, and the hanging basket must stay on several floors.

However, there should be at least fourteen hanging baskets on such a large wheel, and the distance and time traveled between different floors are not the same.

This creates the problem that at the same time there may be up to two baskets that are almost exactly level with the aisle.

In this case, if the person in one of the baskets presses the stop button, all the baskets will stop.

The most unbearable thing is that except for the two hanging baskets normally docked in the aisle, all the other hanging baskets will be suspended in mid-air, and people outside can't get in, and people inside can't get out. ”

"That seems like a real problem.

The kind of elevator we use now, although there are not so many cars, but at least the people in the elevator car can fully control which floor the elevator stops on.

Elevator designs such as waterwheels, although ostensibly increase the elevator's ability to transport personnel, are actually in conflict with the control of multiple gondolas.

As long as any one of the baskets is stopped, all the others will not be able to operate.

If you want to ensure that all the hanging baskets are not affected by other hanging baskets, it is impossible to ensure the normal entry and exit of people in each hanging basket.

If this is an obvious problem that is not solved, your design will not be able to enter the practical application stage. ”

Time on the Internet seems to have stopped for a while, because new problems have arisen, and they have to be given some time to think.

"The distance each basket rises is related to where it is, which is something that cannot be changed.

However, such a gap is not very large, so we can find a way to increase or decrease the height of the aisle on each floor appropriately, and use the slope of the aisle to make up for the height difference in different positions of the hanging basket, which should be feasible.

As long as it can ensure that any of the hanging baskets choose to dock the aisle, the other hanging baskets are parallel to the aisle at the same time, so that there should not be the embarrassing situation mentioned earlier. 2k reading network
