The reservoir in Murono is just a small reservoir. Water can be used before the flood season to lower the water level of the reservoir to the restricted water level of the reservoir, and the restricted water level of the reservoir is lower than the height of the spillway weir top, and the storage capacity between the water level and the top of the spillway weir can be restricted to play a flood storage role. Part of the flood water stored in the reservoir can be used for profit in a planned way during the dry season.

The reservoir can adjust the size of the discharge flow by changing the opening degree of the gate. Due to the gate control, the flood control limit water level of this type of reservoir can be higher than the top of the spillway weir, and the gate opening can be adjusted at any time during the flood discharge process to control the discharge flow, which has the dual function of flood detention and flood storage.

The reservoir is built in a narrow valley, because the slopes on both sides of the reservoir can be used as a natural wall of the reservoir. And Lin Rui and others are going to blow up the dam of this reservoir. They plan to use the reservoir to destroy a major bridge leading to the Orumi Capital Region and completely cut off the enemy's access to supplies from the Orumi Capital Region.

After solving a small number of garrisoned enemies, Lin Rui asked the brothers to guard the surroundings while letting the demolition team led by Sausage begin to work. It seems to blow up a dam, but this is actually not simple.

Whether a space is closed or not directly affects the power of the explosion. Therefore, in terms of common sense, when exploding a rock, whether the bomb is directly placed on the surface or a hole is drilled and placed inside, the effect of the explosion is very different.

According to this rule, if a bomb is used to blast a dam, it should be drilled at the bottom of the dam and filled with explosives. This is supposed to be the biggest damage to the dam, right? But in actual operation, this is not the case.

This is because basically all dams are trapezoidal in cross-section, and the bottom is the thickest. Directly exploding from the bottom is certainly not the most efficient choice; and in the middle and upper part of the dam, the result may not be necessarily Ideal-the blasted gaps in these parts can easily be blocked by sand, or the collapsed parts on both sides of the gap, the effect may not be good.

In actual wars, if you want to destroy a dam most efficiently, which part of it should be exploded with explosives? The answer may not be expected by most people-not the bombing of the dam itself, but the bomb exploding at a certain distance in the water inside the dam.

These shows seem incredible, but in fact have very basic physics principles. For example, the high frequency can break the glass, and the water can be used to cut metal after being accelerated to a certain rate. The energy of many things is often beyond our imagination.

When the bomb exploded in the water inside the dam, the incompressibility of the water produced huge energy and collapsed the dam.

"The British used this method during World War II." Sausage asked his brothers to plant bombs while explaining, "During World War II, the Germans covered the dam to prevent the dam from being bombed. Barbed wire and a lot of anti-aircraft guns were erected along the dam, which made aerial bombing almost impossible. But the British were also very clever. They specially invented the cylinder bomb to blow the dam.

In fact, it is to put the bomb in the tube, calculate the distance, and drop it on the river. This kind of bomb will be like a water float. It will get under the German protective net and then explode in the water near the dam. Burst open the German dam. "

"I don't care about these, I only care if you can blow up this **** dam. We don't have many bombs in our hands. If we fail to succeed once, it won't be enough to come again." Lin Rui shakes Shaking his head.

"Don't worry, I know how to do it." Sausage nodded, "Blasting is an art. In addition to uncontrollable factors such as rock geological conditions, through refined calculations, accurate and reliable equipment, stable quality and variety The explosive charge can effectively control and exert the blasting effect. This is not a simple task. It is much more refined than bombing a tank."

"Then leave it to you. It's best to hurry up. The noise here is not small, and the enemy is likely to have noticed it." Lin Rui shook his head and said, "I will take the brothers on guard, you guys hurry up."

Lin Rui's worry is not unfounded. In fact, the noise they made at the dam has already alarmed the Orumi Federal Army. The enemy has noticed their actions and has reported this information to Elijah, the commander of the Third Division of the Orumi Federation.

Elijah was still annoyed by the delay in taking down the No. 9 Heights, while the trapped troops were unable to break through. After hearing the news, I didn't care for the first time. But Elijah just turned his head back, and immediately stopped the soldier and asked in detail about the movement of the reservoir.

"You mean the reservoir was attacked?" Elijah frowned.

"We heard the gunshots and a company stationed over there lost contact, so the lieutenant = asked me to report the matter. He has already taken someone to check it out." The soldier nodded.

"The direction of the reservoir!?" Elijah frowned, "Impossible, we have restricted their movement, the flanking enemy forces are attracted by us, and the enemy forces on Height 9 are even more unlikely to withdraw. , The remaining enemy forces are still struggling to maintain the siege of our two battalions.

How could a team appear in the reservoir? What kind of force is this, is it a commando or a reconnaissance force? "Elijah thought for a long time, but didn't think of a reason.

He could only shook his head, "Since your people have already checked out, then I will send three more companies to cooperate with you to check out. At present, we really can't call out more people. Remember to report any situation immediately."

"Yes, General." The soldier "slapped" and stood at attention, then turned and left after saluting.

But Elijah's mind could not be calm, he always felt something was wrong. Think about it or turn around and walk to the map. He looked at the military map marked with circles of contours, paced back and forth, and suddenly placed his hands on the edge of the reservoir. As if thinking of something, he immediately turned and shouted, "Give me satellite images, satellite image maps, fast!"

Several officers immediately switched the map on the mobile computer to Elijah. Elijah looked at the map and moved his hand along the satellite image map to the edge, suddenly startled. "They want to blow up the reservoir! In order to cut off the transportation channel between us and the headquarters! They want to trap us here completely!"

"General!" The officers under Elijah were taken aback, looking at Elijah who was almost out of control.

"Don't froze, gather everyone and raid the reservoir." Elijah shouted loudly.

"But we don't have any more manpower. The enemy has restricted our attitude and manpower. We now have only one third company in hand." The officer explained.

"Then directly under the team, commanded by the division, logistics personnel. Organize all those who can still be mobilized, and go with me to surround the reservoir." Elijah personally took the helmet from the orderly and put it on his head solemnly. .
