Chapter 522 Land mines

Previous page        Return to Catalog        Next page

    "Our Chinese nation is the most creative. The four great inventions are all the wisdom of the predecessors. As early as the beginning of the 13th century, special explosive weapons appeared, also known as Zhentianlei. At that time, after the enemy approached,  Use a slow-burning match to detonate and kill the enemy. This is actually the prototype of the early landmine. In the early Ming Dynasty, there were more.  Violent cannons, bombing cannons, stone bombing cannons, invincible mine cannons, etc., are all mines."

    Alas, this intellectual, when he speaks, is very literary. What's the use of you mentioning this?  Qin Baoshan frowned there, this boy is showing off, in order to win Gao Lili's heart, he can do some work by himself, and get married as soon as possible, so as to avoid such pretentiousness.

    "There are many inconveniences in the way of using matchlock to ignite." Finally, Zhang Daguang didn't waste too much time, and soon got to the topic: "So, if you want to become a modern landmine, you must have a qualified detonation method  , Detonators are mainly used for detonation, which are divided into fire detonators and electric detonators. Since electric detonators are difficult to obtain and inconvenient to use, we mainly use fire detonators.¡±

    Zhang Daguang talked about the design of the mines.

    "The manufacturing process of the detonator is complicated. We need experienced firecracker workshop masters to make it. It is also very dangerous. Therefore, this part of the device is produced by the military factory and then distributed to everyone." Zhang Daguang said  : "Everyone uses this kind of detonator to make their own landmines, so as to exert the effect of greater strength in numbers. Put the detonator in the explosive, and put the explosive in a shell, thus forming a basic landmine."

    "Like the one in my hand, the shell is made of special cast iron. The pattern is prefabricated. When it explodes, the shrapnel will explode along the pattern. In this way, the landmine is the most powerful." Zhang Daguang said: "However,  When everyone is making landmines, it may not be easy to find these raw materials."

    The superior is responsible for providing the ignition device. The explosives may be provided by the superior, or they may make the black powder themselves. The shell of this landmine is the most difficult to obtain. After all, it is difficult for ordinary people and villages to obtain pig iron  .

    Although there are blacksmiths, the output is too small to withstand this kind of consumption.

    "We ordinary people use local materials in our homes, such as foreign oil barrels and teapots"

    When talking about this, the old hero below suddenly frowned, and then couldn't help but said: "Comrade experts, I'm very sorry to bother you. Although the pots and pans of our common people are not worth much, they are worth tens of thousands.  You can't let the common people use pots and bowls to make landmines, they are all consumed, so what do the common people use?"

    A broken house is worth tens of thousands of dollars. Those pots and jars in the hands of ordinary people are precious. If nothing else, let¡¯s take a big flower bowl. If it is accidentally broken, ordinary people are reluctant to throw it away.  use.

    Now, if you want to make landmines, let the common people contribute all of these, it is inappropriate!

    The old hero has always been thinking about the common people, even if the people below speak up at this time, they are willing to do anything in order to fight the devils, and they can't be wasted like this.

    Hearing what the old hero said, Zhang Daguang was also a little embarrassed for a while.

    As a military expert, he came to promote military technology. His old profession is in chemistry, making explosives and the like. When it comes to making landmines, he is not the most professional. Now, if he wants to start a vigorous mine warfare, then  He had to reduce the cost of landmines. He originally wanted to adapt to local conditions and use the bottles and cans of ordinary people's homes, but he never thought that the things of ordinary people's homes should not be wasted like this.

    Without these, what else can be used?

    Zhang Daguang really couldn't think of it. Could it be that an iron factory is going to be built here?  The environment here is different from that in the Taihang Mountain area. If a blast furnace is repaired today, it will be blown up by devils tomorrow.  In plain areas, it is not so easy.

    "I have an idea." At this time, Qin Baoshan below said: "How about we use stones for the main body of the mine?"

    If it weren't for the old hero, even Qin Baoshan would be embarrassed to interrupt Zhang Daguang's introduction at this time. After all, Zhang Daguang is also very attentive. He dragged his injured body and prepared for several days.

    It's just that since you have a problem, you have to find a way to solve it. Even if it's a plain, it's easy to get some rocks.

    The main body of mines is made of stones. The raw materials are easy to obtain and the cost is low. There are many stonemasons in the village, so it is very convenient to make stone mines.  Moreover, stone is still non-metal, and it is very difficult for the devil's mine detector to detect it. Therefore, considering all kinds of considerations, stone is the most suitable.?.

    This is of course the advantage of the traversers. Among other things, using stones to make landmines is something you saw in the mine warfare movies.

    "That's right, using rocks as landmines, comrade expert, is this possible?" The old hero asked Zhang Daguang.

    "Yes, of course there is no problem." Zhang Daguang immediately affirmed this suggestion: "In this way, the cost of our making stone mines may be cheaper than making a hand grenade, which greatly facilitates our manufacturing and use.  Next, let¡¯s talk about how landmines ignite. The landmines we release mainly include pull-fire and pressure-fire. In the demonstration just now, the kind that explodes when you step on it is a pressure-fire mine.  "

    In the TV dramas of later generations, in order to attract attention, the director will create a landmine called loose hair. As the name suggests, this kind of landmine will not explode when stepped on, and will not explode until the foot is lifted.  It will explode. In this way, after stepping on it, a tense atmosphere will be created, and there will be thrilling and addictive scenes surrounding how to get the person who stepped on the landmine out of trouble.

    It's a pity that it's all fake.

    Real landmines are not loose. As long as you step on them, they will definitely explode. Unless your brain is flooded, you will create a landmine that does not explode when you step on it, and only explodes when you let go of your feet. Except for the director's use, who else is useful?  ?

    When you step on it, the time-delayed fuze will work, and it will explode no matter whether you loosen your foot or not.  Even if it is an anti-infantry jumping mine, it will explode after letting go of its feet. If it does not let go of its feet immediately, it will still explode after a few seconds.

    Now, Zhang Daguang explained how to operate and use these two fuzes.  (Remember the site URL: www.hlnovel.com
