Chapter 1817: Edward was assassinated?

Fortunately, Marin discovered it early, and discovered this problem before Beihai began to lay cement slabs on a large scale. So, everything is too late.

In fact, this year, because there are no heavy vehicles, the road requirements are actually very low. Under normal circumstances, even without adding "ribs and bones", the cement board road is difficult to be crushed.

However, in an era without heavy vehicles, for cement slabs, the real enemy may not be the pressure of the vehicle, but the expansion and contraction of the internal structure or the huge vibration. Because, this will generate internal stress and shear force, which makes the cement board crack.

In winter, cement shrinks due to thermal expansion and contraction, and internal shrinkage forces are most likely to cause cracks. Once a crack occurs, and a heavier truck rolls over, it may cause the crack to expand. Then, until the cement board is completely broken ...

In other words, the main purpose of adding fiber "ribs and bones" is not to fear that the cement board is not strong enough, but to fear that the cement board will crack itself. Of course, with the addition of "ribs and bones", the strength of the cement board has also been greatly enhanced, and the performance is better.

The strength of reinforced concrete is very limited, but it can help the cement board to resist cracking, but it is undoubted. This is especially important in winter, which can greatly increase the service life of cement board and save costs. Do not use cement board for decades, as long as you persist for a few years without changing, even if Marin achieves its goal. Moreover, the cement slab road is relatively easy to repair, just change a piece.

In this way, Marin set the rules-the main road uses 53mm thick asbestos fiber cement board, while the ordinary roads and streets in the city generally use 26mm thick thatched reinforced concrete cement board.

After all, asbestos fibers have very stable chemical properties and are not easily corroded or deteriorated. Although the cost of the cement board used to make the main road is higher than that of the grass-reinforced concrete cement board, the main road is not much after all, and the amount is limited. The straw concrete cement board, because thatch is not valuable, easy to collect, and the cost is lower. Moreover, after reducing the thickness by half, the manufacturing cost is further reduced, which is very conducive to comprehensive promotion in China.

Subsequently, the newly built cement board factory in Beihai started production of two specifications of cement board. The two kinds of cement slabs produced by it are given priority to the road construction in Beihai. But there will also be roads built in England. For example, the two big enclosures of Northumberland and Isle of Wight definitely need road repairs. As for the border county in the south of Scotland and the highland county in the north, Marin did not rush to build roads there. Because most of the mountains are over there, road construction is very difficult. Moreover, the mountainous areas are prone to debris flow, which is easy to destroy the cement slab road.

In Adelaide's County Wicklow, Ireland, Marin gave priority to providing a batch of cement slabs to support the construction of two main roads for military purposes.

Although County Wicklow has relatively little rain on the east coast of Ireland, it still has more rain than the North Sea country. Therefore, in Wicklow County, concrete roads that are not afraid of rainy days are even more needed. In other words, this road is needed throughout the island of Ireland. However, Marin's current production is not up, and can only supply Adler's Wicklow County first. Moreover, it can only supply one or two routes.

In addition, Marin has to supply New York's needs. Others can wait for a while, a cement board road leading to the Great Lakes region can't run away. Because Marin is now counting on the location of the world ’s first modern oil well, the Drake Well in Titusville. Titusville seems to be near Lake Erie and has oil seedlings on the surface.

Marin intends to start construction of the cement slab road from Philadelphia to the west now. There is no need to hurry, as long as it is under repair. Anyway, with the hollow steel drum roller and cement board, the speed of road repair is called a fast one. The only trouble may be that they will be attacked along the way. After all, the Indians are not fools, they must understand that they will encounter trouble after the road is repaired, and they will definitely block.

However, Marin is now planning to hire hundreds of thousands of workers from Haiti, and he is not afraid. At that time, he intends to transfer the Taino labor force on the island of Haiti to repair this road. Cut trees first, then build roads. After deciding the direction of road construction, first cut down all the trees along the way, and then start building the road with foundation.

The standard for cutting trees is that the trees within a distance of 30 to 40 meters on both sides of the road are cut down. Native Americans' bows made of vines as bow strings are not very powerful, so they have a range of 30 to 40 meters. Keeping this distance away just prevents them from putting cold arrows in the woods and affecting the construction.

And if they dare to walk out of the woods, it is just a taste of the power of the guard ...

...

Once the stone road is repaired, Marin will build a post every 20 kilometers. The post can not only keep horses for messenger transfers, but also build city walls and have military defense capabilities.

This is just the first step. Afterwards, Marin will send farmers to various stations. Then, using the post as a starting point, attack on both sides of the road, cut down trees, and reclaim farmland ... Finally, based on the post, form a walled armed village ...

If you encounter a fierce rebound by the Indians, you will send large troops to clear the Indians around the post along the stone road. Now, the colonial army in North America already has rich experience in jungle warfare. It may not be possible to conquer the entire east coast of North America, but the ability to strike a small tribe alone is more than enough.

Moreover, in the future, Marin will continue to select soldiers from German immigrants, form a 10,000-member army in the North American colonies, learn jungle warfare skills with the more than 2,000 colonial veterans, and finally further sweep the Indians in the jungle ~ www.wuxiaspot.com ~ To seize more land.

The principle of cement road construction is not to seek a straight line close to each other. Except for the stone road that rushes to Lake Erie to find Testerville, other cement roads, as far as possible, will extend along the Great River Plain. The purpose is to occupy as many good places as possible. After all, the plains by the big river are definitely fertile soil, the most fertile.

As the great powers did in Huaxia in the late 19th century, the railway reached its sphere of influence. Similarly, the reach of the cement board road is also the sphere of influence of Beihai. Even more, than the sphere of influence. Because, Marin will directly send troops to control there, or even directly exploit it.

...

After clarifying his thoughts, Marin wrote the wind and quickly issued a series of orders, specifically arranging the road construction and development matters of the North Sea Kingdom, the British homeland and the American colony.

But when he was tired of writing and wanted to move his wrist, Kohler suddenly hurried over and reported:

"Your Majesty, Your Majesty Edward was assassinated!"
