Chapter 437 (1/2)

Paving the road is as difficult as building a house.

First of all, the ground should be treated before paving. The ground should not be soft or wet.

Fortunately, the weather has been good recently. The loess ground is very dry, so there is no need to do drainage and drainage and other hardening treatment, so ye Xi only sent someone to knock the road surface once to make sure that there is no small hole under the ground, and the pavement after paving will not collapse.

Then ye Xi sent a large number of sand and gravel, which were evenly spread on the road surface.

He wanted to build several main cement roads first, but the cement could not directly contact with the soil, so it must be leveled with gravel. Fortunately, the mountains behind Xicheng are full of sand and gravel, so this step is very easy to complete. It took only half a day to transport all the sand and gravel to pave.

After laying sand and gravel, the next step is to pour cement.

In order to make the finished cement pavement smooth, ye Xi installed the mold with stone slab at the edge of the road surface, and separated the blocks. The whole plate area was about 20 square meters.

At this time, the cement was still as soft as mud, protruding one by one. Ye Xi asked everyone to push the cement aside with long wooden sticks. Finally, the ground became as smooth as the water surface.

The second day after the first section of cement road was hardened, it rained for two consecutive days.

Ye Xi was not worried but happy, because he knew that there was no harm in sprinkling more water on the newly poured cement road, which could prevent cracks in the cement road and improve the life of the cement road.

Cement is mainly used to lay several sections of the main road of Xicheng. After the main road is completed, ye Xi plans to lay stone bricks in other places.

During the light rain of those two days, ye Xi led everyone to mine and grind the stones. After the rain stopped on the third day, a layer of lime soil cushion composed of mature lime and clay was evenly paved on the road surface. After leveling, the cement mortar was mixed and the mortar was paved. Finally, the polished stone bricks were paved on the cement pavement.

The paving stone brick is no longer Qingyan, but a kind of rock produced in the mountains behind Xicheng.

This kind of rock is light gray, has a kind of light, like ice crack natural grain, paved on the ground is natural and beautiful, but also does not lose the flavor of primitive simplicity.

Its texture is not as smooth as Qingyan, slightly rough, but this is an advantage, so that even if barefoot on the floor tiles in rainy days will not slip.

The process of paving the road was slow.

With the approach of winter, sunny days are less and less. Two of the three days are raining, so we often stop work.

It was a month after the ground around the stone house community in Xicheng was poured with cement and paved with stone bricks. At this time, the temperature dropped to about three or four degrees, and everyone was dressed in thick fur clothes.

Taking advantage of the last time before winter, ye Xi took people into the mountains to shovel turf.

He planned to lay all the ground around the stone house community, that is, the residential area, with stone bricks, while the rest of the city would be covered with turf to turn it into green space.

The turf is carefully selected by Ye Xi in the forest. The grass is very soft. Lying on it feels like lying on a flannel. Moreover, it grows slowly and can save a lot of time for mowing the grassland.

It's a new thing for everyone to shovel and plant turf.

For the first time, we all know that the grassland in the wild was cut off and covered on the bare soil. Soon, the grassland was tightly connected with the soil, just like the natural grassland.

When the last turf of Xi City was paved, the cold rain poured down.

……

A creak.

The heavy emerald gate was pushed open.

Ye Xi, dressed in a white suit specially made by Jiugong and wearing a hat, said hello to the guard and walked down the steps with bare feet.

It was dark and heavy, and the rain kept crashing on the floor tiles, and then flowed down the drain ditch reserved on the floor tiles to the lake like a stream.

Ye Xi once thought about setting up pipelines underground and building drainage system.

To set up pipes, you have to make them first. Although there is no plastic in the world, and there is a lack of metal and other materials, stone pipes are barely usable.
