The cultivation of fruits and vegetables is not within the scope of mandatory requirements, it is all voluntary, and she is not charitable, and the fruits and vegetables of Tianyu will be profitable if they are planted according to the requirements, so the price is relatively high.

Some people still think that planting rice can fill their stomachs, but some people see business opportunities from here, and when the first batch of planting is on the market, the supply will definitely be less than demand, and it is also the most profitable time, so they cooperate with the company to plant fruits and vegetables.

Tianyu must be a high-quality product, the taste of fruits and vegetables is excellent, with the successive maturity of the market, smoothly occupy a large share in the market.

Nowadays, the common people rely on rice cultivation and have a certain amount of capital, and even ordinary people can consume it.

The first people to grow fruits and vegetables also made a lot of money.

And Su Baiya also understands that if you want the people of the whole country to step into a well-off together, it is impossible to develop slowly.

And these days, the branch of the cornucopia company has been planted all over the country, and Su Baiya has opened a ticket house, and the accumulation of wealth has also grown geometrically.

Too much money and no place to spend it is also an annoyance, Su Baiya remembered the thing she remembered when she first came to this era, if she wanted to be rich, she wanted to build roads.

It just so happens that now that people have money and money, why not fulfill the original idea, not only can it be convenient for the people to travel, but she also does not have to endure the bumps of the carriage when traveling.

The pavement of later generations is divided into asphalt concrete pavement and cement concrete pavement, although the flatness of asphalt concrete pavement is much better than that of water concrete mud pavement, but the process of laying, preparation and so on are very demanding, and it was vetoed without hesitation.

If it is not difficult to make cement simply, the limestone is ground into powder, and then calcined at a high temperature to mature the material, and then mixed with gypsum, slag or soil in a certain proportion to obtain a cement with a low grade.

Its compressive strength is a big gap with road Portland cement, ordinary Portland cement or Portland cement, but in this era, there are no heavy vehicles in later generations to transmit loads to the ground, at most it is an ox cart and horse-drawn cart that pulls more than 1,000 catties of goods, and it can also be used.

Because the bearing capacity of the road surface is small, there is no need to consider the roadbed, roadbed, and even the base layer when building the road, and the weak layer and vegetation on the original road surface are directly cleaned up, and then a certain amount of tamping is done on the original foundation, and a layer of cement surface layer can be added on it.

The road is most afraid of water damage, and after investing such money in it, Su Baiya still wants to keep the road for a few more years.

The cross slope of the road still has to be done, and the drainage ditches on both sides can not be less, the slope depends on the situation, in the absence of a river or a relatively low-lying place, a collection pond must be dug at a distance, which is also a relatively large project.

Su Baiya built a temporary cement making workshop in Zhuwo Village, and prepared the lime and gypsum needed, because the production of cement requires a large amount of slag, and in the end only soil can be used instead.

After the mixture test of different proportions, several kinds of cement with strength and stiffness were obtained, and then these proportions of cement and a mixture of crushed stone were used to make cement concrete, and at the same time, the cube standard specimen with a side length of 150 mm was made respectively, and the compressive test was carried out, and the results obtained were quite satisfactory.

As for the bending test, Su Baiya does not plan to do it, and at present, she is not considering repairing the bridge, which also involves the construction of the foundation.

If it is made into a simply supported beam, etc., whether it is cast in situ or prefabricated, the precamber must be considered, and the prestressed tendon may also need to be worn for safety, and it is a bit difficult to tensile the prestressed tendon in this era.

If it is made into a steel bridge or a cable-stayed bridge, safety is safety, but with the current iron-making technology, the money in your pocket cannot be endured.

As the cement test met the requirements, the workshop worked overtime to produce a large number of finished cement.

During this period of time, Su Baiya has recruited a group of men to form a construction pair to be responsible for the construction of roads.

The specific method of cement concrete pavement has been taught, and the rest is to build a test section to see how it works.

The first cement pavement of this era, Su Baiya chose between Qulan Town and Zhuwo Village.

The original ground has been treated and leveled and tamped, and the next thing is to pull the cement to the construction site and pave it by means of on-site mixing and manual paving.

The mixing of cement concrete is not difficult, and the people of the construction team also joked that it was like mixing paste at home, but it was a little tiring.

After the cement concrete is paved on the road surface, what needs to be done is to vibrate, this step is somewhat difficult and important, whether the bearing capacity of the road surface is good, it depends on whether the vibration is compact.

But now in this era, it is very unrealistic to use a vibrator, Su Baiya had no choice but to ask the blacksmith to prepare a number of large whisks, and reluctantly replace the vibrator for the time being, but the effect is a little unsatisfactory, and it can only be said that talk is better than nothing.

At the end of the vibration, the surface is smoothed, and finally after the cement is initially set, it will start to be sprinkled with water for curing.

About seven days later, the maintenance was over, and the strength of the cement concrete pavement came up, so for the sake of insurance, Su Baiya deliberately doubled the cement maintenance time.

When the people walked on the smooth road, they were pleasantly surprised, and in the rainy season, they no longer had to step on the muddy road with one foot deep and one foot shallow, and the horse-drawn carriage could travel much faster.

The construction of the test section was very successful, and Su Baiya invited hundreds of people to form a large construction team, and her plan made the cement pavement accessible in all directions in Xia Kingdom.

Because it was built free of charge, and the cement pavement also had a lot of benefits, the construction team was warmly welcomed everywhere they went.

Su Baiya suddenly saw a business opportunity here, after the completion of each section of the road, a boundary monument will be erected, which can facilitate future maintenance, and secondly, it can also be used as a marking point, so that you will not get lost when you go to a certain place.

And the business opportunity is in this place, Su Baiya instructed the propaganda department of the construction team to publicize it in every place, if it can sponsor the construction of the road, then in the future, you can leave your name on the boundary monument and the address of your own business.

Some businessmen value the advertising benefits that the boundary monument may bring in the future, while others simply value the ability to leave their name on the boundary monument, so that future generations can "admire" their name.

So every place you go can get a certain amount of sponsorship, which can't be helped, building roads is really too expensive.

However, what Su Baiya didn't expect was that occasionally when she went to some rich places, the sponsors could fill the boundary monuments, and at the same time, in order to be able to rank their names first, they even kept bidding!

In the end, the company that built the road did not come out with any money, and even made a small profit because of the sponsorship.

The construction of the highway was in full swing, and the news of the emperor's critical illness spread on the side of the capital, and it didn't take long for him to die.

After the enthronement ceremony of Young Master Ying, he summoned Su Baiya into the palace and fulfilled his original promise.

In the past few years, Su Boss and Su Lao Er have been following Ying Gongzi to various places to punish corrupt officials and corrupt officials with vigorous and resolute means, which has won the reuse of Ying Gongzi, and he can make steady progress even if he does not have the original promise.

When Su Baiya arrived at the palace, she saw Ying Gongzi, first rewarded her with a lot of property, and then Ying Gongzi ordered the palace people who were waiting in the palace to go out.

got up and walked to Su Baiya's side to look left and right, and said softly: "Mr. Su, I have been thinking about it since I went to Tianyu once that year, can I go again?" ”

Su Baiya smiled: "If the emperor goes to my territory, then don't think about leaving easily." ”
