Chapter 33: Primary Defense System (3)
The prismatic pillar in the middle is more than 20 meters high, and in order to stabilize it, the foundation was dug deeper, and even a hole was drilled into the rock, which was 6 meters deep. The bottom of the pillar is larger, and the top is gradually shrinking, Wei Minsheng feels that this is more in line with the principle of mechanics, because the columns of many high-speed rail bridges are also like this.
AT THE OBTUSE ANGLE OF THE PRISMATIC PILLAR AND THE OPPOSITE POSITION OF THE POURING BODY, WEI MINSHENG ASKED THE VILLAGERS TO MAKE A 10-METER-HIGH CIRCULAR GROOVE WITH A 30MM PVC WATER PIPE, AND THEN ASKED LIU MENGLING TO ORDER TWO LARGE IRON GATES ACCORDING TO THIS WIDTH, AND THE TWO SIDES OF THE GATE WERE DIRECTLY STUCK IN THIS CIRCULAR GROOVE, WHICH WAS DEFINITELY VERY FIRM. The gate made of steel plates with a length and width of 5 meters is not used without a pulley, and anyone can lift it up and be better than a jack gate.
When the pouring body was poured to a height of more than 3 meters, due to the lack of suitable lifting tools, the speed of transporting concrete became slower and slower, Wei Minsheng thought that the wood in the warehouse was full, which was equivalent to 5 months when he did not have to transport the wood, so he dismantled the crane on the cliff. With the help of the crane, the work efficiency has been greatly improved. After pouring one side, put the crane down with a rope and continue pouring the other pouring body.
The pouring of concrete lasted for a month and a half before it was basically completed, and Wei Minsheng brought the custom-made gate in the middle. THE LARGE GATE IS WELDED WITH 8MM THICK STEEL PLATE, ONE OF WHICH IS ALSO WELDED WITH SOME ANGLE STEEL, IN ORDER TO INCREASE THE STRENGTH OF THE GATE, TO PREVENT DEFORMATION, THE TOP OF THE DOOR HAS TWO HOLES, IS USED TO HANG WIRE ROPE. It is completely customized according to the size provided by Wei Minsheng, and the weight of each gate is about 1800 kilograms.
After the completion of the three concrete works, the most troublesome thing is the beam on the top, the span of each beam is about 5 meters, the height below is more than 20 meters, and the scaffolding is not easy to install. Later, Wei Minsheng thought of a way, found a flat ground under the channel, and made more than ten girders of about six meters directly on the ground in a prefabricated way, and then asked Liu Mengling to buy two I-beams seven or eight meters long, and put the I-beams in the position of making beams with pulleys and ropes, and raised them with steel pipes at both ends, and hoisted the girders on the bridge piers with several pulley groups under the support of the two I-beams, and then poured several girders together with concrete to form a bridge deck more than 3 meters wide. Space is reserved between the girders directly above the gate for the installation of the pulley block. Then hang the pulley block on the I-beam, and lift the gate into the previously made round groove through the reserved space.
When the two gates were lowered, Wei Minsheng's base finally became an enclosed space, and other buildings on the bridge deck could be built slowly.
After the scaffolding was removed, there was no road to the bridge deck from under the valley. Wei Minsheng looked at the surrounding terrain and compared it with the map downloaded on his mobile phone, and felt that it was better to build a road to the mountain beam from the "gourd waist" to the plain, and from the mountain beam to the bridge deck around the small plain. If the second line of defense of the "gourd waist" is also repaired in the future, the enemy will break through the first line of defense, and after entering the small plain, he will still be attacked from all sides.
In the past two months, the two villagers who drove the vehicle have been very proficient in technology, Wei Minsheng taught them how to operate the excavator, starting from the simplest digging ditch and filling the pit, after the operation is proficient, the road from the edge of the plain to the mountain beam, all of which are completed by the two villagers in turn, built a 4-meter-wide mountain road on the mountain beam.
The time to repair the road has passed for half a month, and the bridge deck can continue to be constructed, Wei Minsheng went back and bought several large truckloads of bricks to come over, built a brick wall on both sides of the bridge deck, poured a column every two meters, and made a ring beam on the top of the three-meter-high wall to ensure that the wall is solid. A 60CM square window is left on the wall between the columns, and two hooks made of steel bars are embedded in the lintels of the window, and a thin steel plate is hung on the outside of the window, and the steel plate can be supported by a bracket, and those bows and arrows at such a height and such an angle can hardly pose a threat to the people inside. And the people inside can condescendingly smash with stones, attack with fireworks, or throw gasoline bottles, isn't this feeling of war too relaxed?
The supply of weapons such as cobblestones and fireworks bombs on the bridge deck can be sent directly from the plain base by car through the road repaired by the excavator, as long as Wei Minsheng is in the base, there is no problem with the supply line, and he is not afraid of being besieged by the army. Later, buy some excavators and build a ring road around the outer ridges of the whole mountain, like a city wall, which is not only convenient for patrolling, but also equivalent to building a separation belt, even if the enemy has the ability to set fire to the mountain, it can only burn the trees and weeds on the periphery, and it has no effect on the people living in the mountain at all.
Wei Minsheng asked the villagers to dig the pond again, went back by himself, and bought a lot of cement pipes for building sewers, thinking of the fact that boats could be rowed on the city streets reported on the news before, so he bought a large cement pipe with a diameter of 3 meters. The creek on the edge of the pond was introduced into the pond, and the cement pipe was buried with an excavator along the place where the stream had flowed. It was buried all the way to the side of the fortifications, and the water was discharged into the Lotte Creek through several drainage pipes that had been reserved before, and a sluice gate was built outside the cement pipe at the end of the pond to control the storage of the pond and release water to wash the valley.
It took more than four months and a lot of manpower and material resources to invest a lot of manpower and material resources, and the primary defense system envisioned by Wei Minsheng was finally almost built. After sending some timber to the warehouse, Wei Minsheng learned about Xiaobao and the villagers' learning. Xiaobao and those children are equivalent to all of them taking time off to study, so the learning progress is very good, the number of literacy has reached more than 5,000 words, and the simple four mixed operations have been used very proficiently. The rest of the villagers are much worse, but they are more than 2,000 literate, and the addition and subtraction of numbers and simple measurement are no longer difficult for them.
Since everyone is a literate person, then you can choose a better name. Wei Minsheng told the housekeeper his thoughts, and according to the way of typesetting generations in his world family, he set them a character of "both civil and military, inheritance for all generations", so as to distinguish the inheritance relationship between everyone in the family.
Why are there only eight characters? Eight characters can only be used for eight generations. In fact, Wei Minsheng thinks like this, when the family size is small and the scope of population migration is not large, the character generation can clearly know the generational relationship of each person in which family, but if the large-scale population migration occurs, and a more perfect social security relationship, the status of the family will inevitably gradually decrease, and the family-centered modern society has a great rejection of seniority. In the society in which Wei Minsheng lives, it is often encountered that a child who is a few years old is higher than an old lady in his eighties, and in this case, there is no longer the meaning of seniority. Therefore, Wei Minsheng directly set the eight-character naming rule, and the more than 50 villagers in the current base have only three generations in total, and according to their surnames and relationships, they use the three generations of "Wenwu Shuang". The housekeeper's generation is named Wang Wen and Lu Wen, the younger generation is named Wang Wu and Lu Wu, and the underage generation is named Wang Shuang and Lu Shuang, and those of the same generation try not to take the same name. After determining the rules for choosing a name, Wei Minsheng asked the housekeeper to convey his meaning to everyone, and let everyone find a favorite character among the Chinese characters they learned to form their own names.
