VII. The Great Project (II)

The project is simply repeated, that is, the soil is built up layer by layer, very monotonous work, Han Wenzheng of course understands that this project is definitely not only a project of one or two years, but a project of two hundred years, so the quality of the project must be high, if the quality is not high, it only took more than ten years to cross, then it will be a waste of their time, so the requirements for quality have reached a harsh point, so harsh that even Qiushui is a little blind.

First of all, the ground is flattened, the soil on the ground is loose, first to tamp, seven all-metal organs will weigh ten tons of ramming high to five or six meters in the air, and then let go of the hand, let the ramming down heavily, the ground will immediately sink down a piece of the boss, the bottom area of four square meters of ramming down so smashed down, that is to press the ground solidly,

In one place, it has to be rammed eight times in a row, and the mass of each rammer weighs ten tons, that is, these all-metal organs with several huge arrays have the strength to use such a large and heavy rammer, after the ten-ton rammer has been smashed eight times in a row, the ground has been so strong that even the steel fiber can not be inserted, Han Wenzheng believes that this should be able to withstand the huge pressure brought by the 100-meter dam.

After the ground is tamped, then the soil and stones are spread on it, and then tamped, so that it is rammed layer by layer, until it is 100 meters high, such a huge project, it is definitely a big test for two people.

In the past three years, Han Wenzheng and Qiushui have revised and modified the design drawings again and again, and after the last, Han Wenzheng decided not to completely adopt the design of Qiushui, that is, not to completely use the design of the continuous dam, but the bridge structure, from the ground, every 30 meters away from the distance to vacate it, start to build the bridge, and then build the bridge to 140 meters high and then use a big tree to connect the two bridges, although the bridge structure is much more troublesome than the way of damming, and the speed of the application is much slower, but it can save a lot of engineering volume, and it is much faster to calculate。

The bridge is also specially calculated, the bottom of each bridge is 170 meters long, the bridge hole is 30 meters long, in this way, basically can save about one-sixth of the amount of work, after two people poor for half a month of calculation to determine, this way is feasible, Qiushui is naturally recognized this design, but, even so, the total amount of work is still about 1.2 billion cubic meters, or that huge.

However, fortunately, this is just to build a canal, not a hydropower station, so there are not so many additional buildings, and there is no need to be so particular, if it is to build a comprehensive project like the Three Gorges Project, it is not necessary to think about it, this point, Han Wen understands, although the amount of this project is large, but there is no scientific and technological content, so that the two people can cope with it.

When the bridge is built, the huge trees are used on the iron plate, so that it is relatively stable, enough to withstand the water pressure several meters deep, as for how to hang these large tree trunks more than 30 meters long, as thick as one meter in diameter, and weighing tens of thousands of catties to a height of 100 meters, this one can only be Han Wenzheng himself, using a pulley group to hang them, the pulley is not very difficult to make, so it is not very difficult. It's just that because of Han Wenzheng's decision, the towering ancient trees around him have fallen into bad luck, and in order to build this dam, I don't know how many towering ancient trees in the road have been cut down and used, at this time, Han Wenzheng has no other way to think about it.

Qiushui once proposed to use steel to replace the big tree, but with the output of the two of them, it is impossible to use steel at all, so it can only be done temporarily.

Mechanics are not tired, they can work non-stop, but they also have to rest, after all, they are only made of wood, not steel, of course the wood will be damaged, therefore, these organs often have to be repaired, for example, because the wood is misplaced, there is a mistake in the formation, so it is necessary to recalibrate the pattern of the formation, etc., this is also a relatively large project, and the new mechanism people are constantly producing, anyway, as long as there is wood can be produced, wood, yes, just hate that the speed of production is not fast。

As more people join the work, the speed of construction will of course also be accelerated, anyway, these are just free labor, no need to use in vain, they are made to be used.

Every day, Han Wenzheng has to be tired like a dead dog, go back to the city lord's mansion and fall asleep, whenever he goes to rest, Qiushui will take over his work, even if it's dark, it doesn't matter, anyway, two people can see in the dark, as for the machine people, they have no difference between dark and daytime, no matter what the environment is, they can work, so there is basically no possibility of stopping work on the construction site.

The beasts nearby are also unlucky, because Han Wenzheng occasionally remembers that blood can make the soil more closely bound together, which is conducive to the improvement of the quality of the project, so there are countless beasts that have been bad, caught and bred in captivity, breeding, and then killed to take blood, and when they have exhausted the last drop of blood, they will turn into meat and be sent to the warehouse for storage, so to speak, Han Wenzheng This guy has really done a lot of killing for this project.

The annual precipitation in the place where Yanhuangcheng is located is more than 1,500 mm, so there will be several rainy seasons every year, therefore, when it rains heavily, the construction site will stop, and the two couples can sit down and rest for a while, but when they rest, they will still discuss how to build faster, whether there is a better way, or improve the personnel of the agency, etc., basically there is no nonsense.

Of course, sometimes they also talk about two love words, Han Wenzheng will also kiss Qiushui a few times, using these occasional opportunities to flirt, both of them feel a different kind of stimulation, but they have no plans to get married. However, in this kind of time when only two people survive, the relationship between them is naturally thickening day by day, although there are no sweet words, but they can feel the love between them, time, is the best storage agent for love, but also the best storage agent.

After the unremitting efforts of the two husbands and wives, a new generation of more powerful organs has finally been developed, with a force of 3,000 catties, and the speed of movement has also accelerated, reaching 20 kilometers per hour.

Two years have passed, but only ten kilometers of distance has been built, only about eight percent of the total amount of work has been completed, it is too slow, this project is really difficult, and it is natural to be slow, but Han Wenzheng is not satisfied with this speed, he will think of a new construction plan when he is free, after all, he and Qiushui are not specialized construction talents, there are still ways that have not been thought of before, but I didn't think of it, and now after two years of work, he also has a deep experience, so he is trying to find a new plan。

The soil is tamped first when it is controlled, and then cut into a mud brick of one meter by 0.5 meters and a height of 0.5 meters, such a mud brick weighs about a ton, and the new organ can be moved, so that the tamped mud brick is naturally more than loose soil, therefore, under the same transportation speed, however, the amount of transportation has more than doubled.

When the mud bricks are transported to the construction site, and then the mud bricks are thoroughly ground up by the agency people, this is the new method that Han Wenzheng came up with, in fact, this is not a new method, this is actually a method for farmers in the southern part of China to build houses, but, as a northerner, he has never seen it, besides, he lived in an era when no one has built this kind of house built purely from mud bricks, so he couldn't think of this method for a while.

It's just that the brick wall has also produced a new problem, the problem of adhesives, there is no cement here, there is no cement as a binder, the combination between mud bricks and mud bricks is not strong, in order to find a suitable adhesive, Han Wenzheng has not slept well for a month, and after the worst, he still let him find a way, this solution is still remembered by the story that his father once said.

Build a cellar, burn the limestone into lime, dig a small pool, put the lime into the pool, inject water, and dissolve the lime, you get the lime slurry, and then pour the white sugar into the lime slurry, mix it in a certain proportion, it becomes a special binder, the name of this adhesive is called sugar ash, its function is more than cement, it is a commonly used adhesive in ancient Chinese buildings, even if it is used to build a city, it is very strong, it is also very easy to use, and the raw materials are not difficult to find. (Sugar Ash is just the name of our country here, and I don't know what the names of the other places are.) I have forgotten the specific composition of sugar ash, which is probably what it looks like, but I heard from the older generation that it is really very strong, much stronger than cement. I can't find any information about sugar ash on Baidu.,I can only write it out from memory.,Don't scold if it's wrong.,If there's any information, it's best to give me a copy.,Thank you.。 ）

Limestone is abundant in these places, as long as it is dug up, as for white sugar, although there are no sugar crops such as sugar cane, it can be exchanged for food from the urban system, which is not a special item, it can be exchanged. Although this consumes a lot of food, the last thing Han Wenzheng lacks now is food, there is a lot of food, besides, if the food is not enough, no problem, just pull a team of people to open up the wasteland and farm, it's just a little troublesome.

After using this mud brick method, the speed of construction is really a lot faster, but it is also troublesome, but Han Wen will not be satisfied, one day, he thought, since you can use mud bricks, why can't you use stone bricks? He cut the large stones on the mountain into bricks, which is also possible, and also omitted the time of rammed earth, and the stone is always harder than the earth, so he cut the stone on the mountain into a stone brick as big as the mud brick with a sword, and used it as the base of the bridge, and then used the mud brick on it, so that the safety and solidity of the bridge can also be strengthened.
