the road at home gate seems to be in a semi maintenance state forever, and one or two months apart, you can see the worker's master to dig the road to the world.
in feeling that it has created so many jobs miraculously, I also secretly hope: can it not be so good that it is not better to toss the resources and energy to other creative things?
foreigner seems to have a general idea with me. Let's see how people repair the road.
their pavement is more than I can be, so few people.
but people have toss up a NB "printer", a small shovel to carry bricks, two workers to adjust the brick, the road brush from the bottom "print" out!
it is said that the 6 meter wide pavement can be paved for more than 400 meters a day, and this quality, just looking at the shovel - brick car, can run directly on the paved road.
estimate that we can consolidate and consolidate the project so that we can put it into operation.
this is the real science and technology Ah, liberate human resources and engage in more advanced labor.
, of course, this machine is obviously not suitable for our country, "to get rich and repair the road", the cost of the pavement is too transparent, and the road that is laid out is not so easy.
