Chapter 167: Destruction Plan (Happy Chinese New Year's Eve)
Swaraj subconsciously asked rhetorically.
Marlowe glanced at Gu Ji, his eyes turned thoughtfully, and then he confirmed that his previous feeling was not wrong.
"Comradeship" is very applicable in any country in the world, and as soon as he heard that Gu Ji had also served in the army's mountain division, Swaraj's attitude changed significantly, and he agreed to his application to go with him.
About 20 minutes later, at the request of Fatima's phone call, the Darjeeling county magistrate arrived with more than a dozen transport trucks and engineering teams and began to help the soldiers of the Special Border Force carry military TNT explosives.
"Vidi, be careful!"
"Don't worry."
In the face of Fatima's concern, Gu Ji shook his shoulders, tied his backpack tightly, and then got into the transport vehicle.
The 18 men sent by the 57th Mountain Division, excluding Swaraj and his deputy, were exactly 16 people, divided into two teams, A and B, and learned through chat and inquiry that their task was not only to provide military explosives transportation, direct detonation, but also to be responsible for armed protection, and as for the process of filling explosives, they needed the assistance of the state government engineering team.
Come to the dam.
The first thing that comes into the ears is the loud sound of "bang-la-la", which is the movement produced when the dam sluice hole is discharged, the Alibul dam belongs to the medium-sized dam, the width of five or six hundred meters, the height of more than 70 meters is also magnificent, the long dam body crosses the water of the Mohananda River that is rolling north, and the iron tower stands abruptly on the dam body, and the power grid extends in all directions.
Alipur Dam was the first major dam in northern West Bengal.
The reason why Gu Ji chose to blow it up, or rather, blow up the three dams in common is the size, and the importance of their location!
First of all, the Alipur dam is large enough to store 3.62 billion cubic meters of water, and the location is even more important, because of the huge drop of about 50 meters upstream and downstream, it is equipped with 565,000 kilowatts of generating units, which can provide sufficient power for the surrounding area.
At that time, when Gu Ji chose to blow it up, officials and experts from the two major departments of finance and taxation and water conservancy strongly opposed it.
But the real danger is here, only four sluice holes, the speed of drainage is very limited, once the upstream water volume surges, causing the dam to burst, billions of cubic meters of water smashed down at the same time, don't think about it, it will definitely cause the downstream medium and small dams to burst continuously, and cause a super flood that is rare in a century.
Arrive at the central control room of the dam.
Gu Ji and Marlowe handed over the documents to the staff, and looked at the monitoring data by the way, and sure enough, the water storage position of the dam was already on the edge of the warning line, and the little water discharged from the sluice hole could not discharge the reservoir to a safe position before the tropical storm came.
After checking the structural drawings of the dam at the site and confirming that the original drawings provided by the presidential palace were correct, he asked the dam supervisor to direct the evacuees, and then began to implement the first bombing plan with the soldiers of the Special Border Force.
All hydropower stations in the world have two shapes, one is a gravity dam and the other is a stress dam.
The gravity dam is very easy to understand, that is, the dam that relies on its own weight to block the turbulent river water, which is very strong; The stress dam is a bit more complicated, it uses its structure to transmit the strong pressure brought by the river to the cliffs on both sides, so as to use the stress to resist the huge water pressure, as was the case with the Gohati dam that Guji saw in Assam.
Compared with gravity dams, stress dams save labor and time, only about one-third of the concrete is needed, but this kind of dam has a disadvantage, if you destroy one of the points, then the strong water pressure will cause the dam to collapse, causing a catastrophe.
Gu Ji is trying to take advantage of this shortcoming.
In 1943, the British Air Force carried out the "Operation Correction", which was to bomb the Ruhr Dam, which also took advantage of this structural shortcoming, and used only three 4.5-ton bombs to complete the Ruhr Dam, which required at least 40 tons of explosives to blow up.
Fortunately, the vast majority of dams in India are stress dams.
Otherwise, if it encounters a concrete gravity dam like the Three Gorges of Xia, basically there is no need to think about it, and conventional weapons will not even leave a pit when they are smashed into it.
Fortunately, Gu Ji's goal is not to destroy the dam completely, but to find a way to blow up a gap, which can not only speed up the drainage of the reservoir and avoid large-scale flooding when a tropical storm hits, but also repair it afterwards with minimal cost.
After looking at his action plan, Marlowe first asked the technicians to use the Indian SWITCH drone to fly around the dam to confirm the general working environment of the dam, and then arranged for the engineering team to transport, hoist, and punch the explosives.
"Your plan is well designed, you only need 187 kilograms of TNT explosives to complete the task, it's very easy!"
"Since it was your military's attack, the technical aspect must be much stronger than that of ordinary engineering teams, so I used the more difficult multi-row hole differential blasting method."
Facing Marlowe's inquiry, Gu Ji replied casually.
Hearing the technical term "multi-row hole differential blasting", Marlowe knew that he really knew blasting technology.
Differential blasting is an advanced method of simple shallow and deep hole blasting, which mainly refers to the complex blasting method in which the traditional Chinese medicine package of adjacent blast holes is packed in a very short time, generally calculated in milliseconds, and detonated in a pre-designed order.
It has many advantages, first of all, the amount of preparation is less, a large number of rock blasting work can be completed in a short time, and it is suitable for rocks of various hardnesses, especially in the dam such a place with complex terrain, not limited by construction conditions, and it does not need special rock drilling equipment, the excavation chamber generally uses a rock drill to excavate, and all the deep hole blasting can be used in the chamber blasting.
The most important thing: a large amount of blasting at one time, reducing the number of blasts and the time to avoid guns!
In other words, once the reload is completed, the blast can be successfully completed in one attempt, which greatly saves the mission action time.
The more money you save, the more time the reservoir has to release and the safer it is!
Relying on the experience of building blasting honed in the bomb level, Gu Ji designed a very simple, but very practical "U" shaped multi-row blasting for the Alibul Dam.
The whole process of drilling and filling the explosives takes about three or four hours.
This is still with the help of the construction engineering team of the state and county governments, if it is only done by Gu Ji and the special border troops, I am afraid that a dam will not be blown up in the year of the monkey.
After all, this is a super building hundreds of meters long and more than 70 meters wide, which can hold back billions of cubic meters of water.
In order to "rub" the mission experience, Gu Ji also took the initiative to join the work of filling explosives.
When encountering some difficult holes, it is also necessary to use safety ropes to hang from high altitudes, and some engineering and technical personnel cannot do it, so they can only hand it over to the soldiers of the special border force.
Plateau heavy work is not a problem for these army elites at all, not to mention that they have been training in the high altitude of the Himalayas in northern Assam for a long time, and their physical condition has long been adapted to high-intensity hypoxic operations.
And Gu Ji's possessed "Vidi" physical basic quality this time is not bad, without any attribute weakening, plus he chose the blue level of endurance improvement mark before, relatively speaking, the physique with high endurance is less likely to cause altitude sickness.
Finally.
After more than three long hours, all the explosives were accurately filled into the holes designed by Gu Ji.
"All personnel ready to evacuate! Evacuate now! ”
"Listen to orders! Evacuate quickly! ”
……
With Marlowe and Gu Ji shouting loudly, the county government engineering team packed up their equipment and drove away from the dam, and the two of them checked the dam one last time, and only after repeatedly confirming that no one was missing, did they return to the car.
During the drive down the mountain.
Gu Ji took out the phone.
"Fatima, how are you doing over there, have the people downstream of the dam safely evacuated from the danger zone?"
"It's all been transferred, don't worry."
"Captain Marlowe, you can blast here at any time!"
After receiving the confirmation, Marlowe urged the soldier to increase the throttle and drive towards a hill to the east of the town, and only after confirming that he had reached a safe distance did he raise the walkie-talkie, "Krel, the location is safe, you can prepare for the blast!" ”
"Krell received, now ready to blast, three, two, one! Initiation! ”
The last voice fell, and the finger tapped the button.
Bang! Bang! Boom——!
In the dark night sky, several fires flashed in the distance, and the next moment, the deafening explosion sounded at an extremely fast speed, even if it was a kilometer away, it was very clear, Gu Ji was still immersed in the explosive power of the military TNT explosive, but the dam set off an earth-shaking sound in his carefully designed blasting.
In an instant.
The earth is cracked, and the smoke and dust are filled.
After a violent tremor, a dam burst and landslide, a large number of boulders fell from the dam body into the river below, and in the blink of an eye, the water of the reservoir crashed down from the broken gap, roaring, like a herd of frightened wild horses, rushing from the upstream reservoir, overwhelming.
In less than a few seconds, the water level of the Mohananda River began to skyrocket, and the current became rampant, from top to bottom, pouring for thousands of miles, and the river bank could not withstand this sudden violent impact, and the water instantly flooded both banks, and gradually pressed towards the town.
Seeing this scene, Marlowe once again commanded the technical soldiers to fly the drone to the top of the dam.
Judging from the screen, the center of the dam was blown out of a "U" shaped gap of more than ten meters in size, and the flood of the reservoir is pouring frantically from the gap, and because it is a stress dam, under the premise that the dam body bearing key is damaged, as the water flow has been scouring, the concrete around the crack will continue to break and fall, causing the gap to become larger and larger, so as to achieve the purpose of finally discharging the reservoir to the safety line.
"Colonel Swaraj, the first dam blasting plan has been successfully carried out!"
Just as Marlowe was reporting the situation to the commander, Gu Ji took out his binoculars and looked down at the bottom of the hillside, where the stagnant water was rising at a rate of more than 10 centimeters per minute, like a hungry wolf, devouring the surrounding villages and the land, especially the downstream areas, a vast ocean.
That's why he asked Fatima to notify the county government in advance to relocate the people.
If the dam is blown up, there will definitely be a flooding problem, but the damage is already mild compared to the actual flood, and as the reservoir is discharged, the short-term rise will slowly recede.
After the task was completed, Gu Ji followed the troops back to the headquarters.
Due to the accumulation of water, the helicopter also changed positions.
Gu Ji found Fatima and learned that the logistics would be managed by the central government's finance and taxation department, so he found Swaraj and began the bombing of the next dam as soon as possible.
Eleven o'clock in the evening.
Transport helicopters landed near the second dam.
This is the Murshidabad district of the Murda Governorate, which is located in the central district of northern West Bengal and is the second key location that is prone to large-scale flooding.
As with the previous dam blast, under the communication arrangement of the central government, the people continued to move people, drill holes, charge charges, and detonate according to the previous path.
However, because the dam is larger than the Alipur dam, it will take longer.
During the loading process, the tropical storm also gradually invaded here, Gu Ji could clearly feel the temperature and air pressure drop, and his breathing was a little stuffy, and it didn't take long for a light rain to fall in the sky.
Fortunately, military explosives are not afraid of this little rain at all.
But Gu Ji had always been worried about the dam in southern West Bengal, so at his urging, more than four hours passed, and a fire once again crossed the darkness, and a series of loud noises broke out, and the second dam was successfully bombed.
Looking at the rapidly pouring reservoir, Gu Ji asked Swaraj to take off as soon as possible while the rain was light.
The distance from the north-central to the south of West Bengal is not short, about 100 kilometers, and almost 20 minutes later, through the iron sheet of the cabin, Gu Ji heard the rain around him getting heavier and heavier.
Suddenly, a flash of lightning streaked across the night sky ahead.
"Doodoo ......"
The helicopter cockpit sounded an alarm, and the pilot immediately took out his walkie-talkie and shouted:
"Colonel Swaraj, there's a thunderstorm ahead, it's very dangerous, we can't fly any further!"
"Landing nearby!"
In desperation, Swaraj could only order the transport helicopter to land in the nearest open area of the plains.
Fortunately, it is not far from East Midnapur County in Midnapur Prefecture, and the third dam that Guji wants to bomb is the Faraka Dam, which was strongly refuted by the Minister of Water Resources.
The dam is also the largest of the three, with a length of more than 800 meters and a height of more than 80 meters, and like the first dam, it also relies on mountain streams.
After the landing of the transport helicopter.
Fatima immediately followed the list and contacted the county magistrate of Midnapur Prefecture.
But what she never expected was that no one answered the phone, she thought it was because of the rainstorm, and the county government was in a busy state, so she called several times in a row, but still no one answered.
"Vidi, no one is answering the phone in Midnabul."
"Try someone else."
"The phone can't be connected."
Fatima dialed again, and the result was still the same.
