Chapter 336: Practice Brings the Truth


The two blasting tubes waited for a long time before exploding, and they exploded at intervals.

After discussion by the engineer platoon, He Jinhai finally figured out the source of the accident.

The problem all appeared in the length of the fuses.

The fuses of the blasting tubes were installed by the soldiers themselves.

There were no standards and the lengths were different.

As a result, the fuses of the two tubes happened to be very long, so the blasting time was too long. .

The root cause still lies in the manufacturing process.

There is no standard for the length of the lead wires.

The soldiers installed the lead wires according to their own ideas, which led to this result.

Practice is indeed important.

Zhang Wei and the others are doing a test explosion.

It seems that there is no problem, but if this happens on the battlefield, there will be a big mess.

The time from the time when the two blasting tubes are fired to exploding is more than 20 years.

Seconds, on the battlefield, it is entirely possible for the Japanese army to take advantage of this time to throw out the blasting tube.

This blasting tube is equivalent to being sent up in vain.

However, the damage effect is still very satisfactory.

Half of the semi-hidden bunker that was blasted collapsed.

The logs and structure of half of the bunker were blown apart by the blasting tube.

All the sandbags around it were scattered, and a hole was opened.

Inside the bunker It was a mess, and with this damage effect, there was basically no possibility for the people and equipment inside to survive.

Two 3.5-pound long blasting tubes are enough to take out a semi-hidden bunker with a civil structure.

After the first blasting was completed, in view of various problems that occurred during the test blast, Zhang Wei ordered that in the future, when the engineering platoon manufactures blasting tubes, the production must be as standardized as possible, and the length of the lead wires must be unified.

A situation like today must not occur.

The gap time before blasting should be controlled within twenty or twenty seconds to prevent the Japanese army from carrying out counter-projection.

With the experience and lessons learned from the first test blasting, the next one was much smoother.

The squad leaders and deputy squad leaders of the engineer platoon took turns to work.

The detonation test of a concealed bunker with a two-pound blasting tube, the ground blasting test of a three-and-a-half-pound blasting tube, and the ground blasting test of a two-pound blasting tube were carried out successively. and blasting experiments in trenches.

Ten 3.5-pound blasting tubes and ten 2-pound blasting tubes were burned out.

After the blasting was completed, the most valuable thing was the data collected by hand.

The final conclusion was that using a 3.5-pound blasting canister, two can completely destroy the semi-hidden bunker with a civil structure.

Using a two-pound small blasting canister, it would be enough.

Three or more.

In the fortification blasting test, the lethality of a three-and-a-half-pound blasting canister can kill an entire shift and a half, while the lethality of a two-pound blasting canister is much smaller.

Facts have proved that in large-scale offensive operations, the three-point-five-pound blasting tube should be mainly used.

It has a strong lethality against infantry in the trenches, bunkers and ordinary trench fortifications.

On the contrary, the two-pound blasting tube The blasting tube is much inferior.

But the advantage is that it is light in weight and small in size.

In an emergency, the two kilograms can be used as a grenade and thrown outside.

In complex terrain, when long blasting tubes cannot be delivered, these two-kilogram blasting tubes can play a substitute role.

If there is a positional battle with the Japanese army and a close attack, these two-kilogram small blasting tubes are more useful than the three-and-a-half kilogram blasting tubes.

The large blasting tube is larger and can be used flexibly in trenches.

Another function of the blasting tube, mine clearing, has not been tested.

The teaching brigade does not have mines in hand, and the minelaying ability is not good.

However, when detonating on the ground, the killing area of ​​a single 3.5-pound blasting tube can destroy a battle formation of half a squad.

The blasting power of the two-pound blasting tube is pretty good, and it covers a relatively large area.

If it encounters a landmine, it can open a safe passage.

He Jinhai recorded the usage and lethality of the blasting tube.

After discussion with He Jinhai, Zhang Wei and He Jinhai concluded that the production of the blasting tube was generally successful and added a weapon for killing enemies to the teaching brigade.

Apart from the discussion with He Jinhai, Zhang Wei and He Jinhai They also sought advice from the engineers in the platoon who made and used the blasting tubes.

The soldiers in the engineer platoon may not understand high-level things, but they have rich practical experience and are direct users.

Their opinions and experiences are more useful to users on the battlefield.

These useful opinions are often unexpected by officers like Zhang Wei.

A squad leader of the engineer platoon believed that the current blasting tubes were not waterproof and moisture-proof.

The engineer explosives that were distributed had a layer of yellow waterproof paper in the box, which was laid under the explosives to prevent moisture.

This squad leader has been in the army for many years.

In a previous battle, his unit was affected by moisture due to mortar shells and grenades.

As a result, when the troops received fire, many mortar shells could not be fired at all.

Even if they were fired, there were still many unexploded shells.

Explosive bombs, firepower dropped sharply.

The wet grenade broke into two halves after exploding, and had almost no lethality.

In the end, the troops suffered heavy losses and suffered heavy casualties.

Therefore, this squad leader is particularly sensitive to the problem of moisture in ammunition.

When placing the explosives in the batch of blasting tubes used by the teaching brigade for testing, the explosives were directly in contact with the steel pipes and were inserted without any treatment.

After being reminded by the squad leader, I found that the effect of use is easily affected by moisture during storage.

The cavity between the explosive and the pipe wall is prone to water ingress and moisture.

The squad leader suggested taking apart the waterproof paper in the explosive box, rolling it into a cylinder with plugs, spreading it into the steel pipe, and then filling the pipe wall with waterproof paper with explosives to take moisture-proof measures and make the seamless steel pipe The interior is tighter, making the bulk explosive more secure.

Another first-class soldier wanted to attach a wooden pole to the blasting barrel.

He said that it could shorten the distance of the attack.

When fighting in the bunker, he could stick the pole into the bunker's nozzle and reduce the area to be bombed.

The opinions of these soldiers were very useful.

Zhang Wei praised them greatly and informed the engineer platoon to provide extra meals for three consecutive days to reward the engineers for their hard work these days.

The soldiers naturally cheered.

Zhang Wei and He Jinhai recorded the opinions of the soldiers one by one.

These low-level officers and soldiers fighting on the front line and working hard actually have many useful ideas.

It just depends on whether the officers can ask them out and use them.

Bring out the cleverness and wisdom of the soldiers.

The wisdom of the working people cannot be underestimated, and the same goes for the soldiers at the bottom.

Soldiers in the national army generally do whatever their superiors say.

Their subjective initiative is not very good.

They basically work as soldiers and get paid to do things.

Of course, now this system has collapsed.

Not only do the soldiers have no money, many of them don't even have enough to eat.

The officers did not pay much attention to the soldiers, and the two sides were almost out of touch.

It was difficult to convey the following experiences, and the soldiers had to muddle along, which ultimately led to the slow progress of the army.

Many of the experiences and lessons that were originally summed up quickly took several losses before they could be gradually Change it.

The engineer platoon came up with a lot of good ideas today.

Zhang Wei said that in the future, everyone can speak freely as long as they have good ideas.

As long as the ideas are useful, Zhang Wei will be greatly rewarded
