While they were talking, a concrete tanker drove up in the darkness, and with a roar, a large amount of concrete poured down, burying the wellhead tightly. Zhou Yun and Ye Han looked at each other, and both of them felt relieved at the same time.
The mission continued, and the wellheads that were either blown up or intact were found one after another, and each one was sealed by the military. No matter how good the giant ants are at digging holes, they can never dig through the solid concrete.
However, everyone knows that with a little effort, the giant ants can dig new passages, and it is only a matter of time before they invade the city again.
The situation is still serious and it is far from time to relax!
The mission went so smoothly that Ye Han became suspicious. When the convoy passed an intersection, the military suddenly reported that a wellhead was found in the middle of the street.
Ye Han immediately checked his tablet, but could not find any sign of a sewer at this intersection. He couldn't help but be confused: "Old Zhou, when was this picture taken? Is it accurate?"
"I don't know either!" Zhou Yun said innocently, "Let's go over and have a look!"
The armored vehicle drove near the well. Ye Han used the light of the car's headlights to check and saw an intact manhole cover in the middle of the street.
"Should we seal it or not?" Ye Han asked.
"Let's go over and take a look." Zhou Yun opened the door and got out of the car. Before he could reach the well, another convoy rushed nearby.
Several soldiers jumped out of the car. When the leading officer saw Zhou Yun and Ye Han, he saluted politely: "Hello, this well is our mission."
Ye Han suddenly realized: "That's it, no wonder it's not on our drawings!"
Zhou Yun also felt relieved and said with a smile: "That's good. We just saw a well that wasn't on the drawing and didn't feel like taking a look."
The captain officer also smiled: "Understood!" After saying this, he waved his hand and several soldiers immediately rushed to the well and quickly opened the manhole cover.
A soldier whispered: "Company commander, no problem!"
The captain nodded: "Let's go!"
The soldiers boarded the vehicle and the convoy left quickly.
Ye Han was confused by this scene and asked inexplicably: "Why are you leaving now? They didn't seal the well?"
Zhou Yun also felt strange. When he walked to the well, he was speechless. He walked back and shook his head, "No, this is a communication well."
Only then did Ye Han remember that there was such a thing as a communication well, and couldn't help crying or laughing for a while.
What the bureau gave Zhou Yun was a sewer pipeline design drawing. The team just got it must have been a communications design drawing, but they didn’t know which communications company it belonged to.
According to this routine, there must be a dedicated team to check the underground engineering design drawings of water supply, gas and other departments one by one!
Ye Han's guess was absolutely correct. Not long after, the team met another team.
How did he know that with the city government's order, all industry departments involved in underground engineering such as municipal administration, water supply, environmental protection, and communications have all taken action, and the underground pipeline construction drawings of Jingjiang City over the years have been found in detail.
A few hours later, the team sealed all the sewer wells marked on the map, even those that were blown up during the day. When the team met up with another team near the city wall, the underground wells directly below the team
Deep down, it happens to be the main sewage pipe leading to the sewage treatment plant!
The command center analyzed that although giant ants are good at digging holes, the time that giant ants appear in the suburbs is too short, and it is simply unrealistic to dig from outside the city into the city within 48 hours. Therefore, the most likely possibility is that the giant ants accidentally dug through.
Sewage pipelines in Jingjiang City.
Giant ants mostly come out of sewage wells during the day, which is the best proof.
For this reason, the city government decided to blow up the main sewage pipes and block the passage for giant ants to enter the city to buy time for citizens to evacuate.
The two convoys joined forces and found a sewer well that led directly to the main pipe. They carefully sent a large number of explosives into the well and were ready to blast the main pipe.
What is strange is that the military did not blow up the main pipeline immediately, but reported the situation to the joint command center and waited patiently under the order of the joint command center.
In the next hour, the command center received reports from several other teams. When all the drainage pipes leading outside the city were ready for blasting, the joint command center gave an order and hundreds of tank trucks appeared in the city.
On the streets, a large amount of gasoline is poured into the drainage system through reserved wellheads.
After a while, the ignition order from the joint command center was transmitted throughout the city via radio waves.
More than a hundred soldiers fired incendiary bombs into the wellheads at the same time. More than a hundred sewer wells were successfully ignited one after another. The high-concentration oil vapor in the wells exploded. The pillars of fire that exploded in the wells were tens of meters high, and the fierce pillars of fire lit up half of the sky.
The team that had already prepared for the explosion also received the order to detonate. With the order, a large amount of explosives buried in the ground detonated instantly, causing the ground to collapse instantly. Concrete tankers that had been prepared swarmed up and poured a large amount of concrete into the explosion pit, completely blocking the drainage pipes.
.
Even if humans can one day drive the giant ants out of the Jingjiang River and regain this devastated city, dredging the drainage system will still require a huge amount of money and labor. It will be easier to lay new pipelines.
The gasoline in the well burned fiercely, and the hot flames roared along the drainage pipeline. In a short time, the underground drainage pipeline turned into a blazing death place.
The giant ants remaining underground suffered a devastating blow. Even if they were not burned to death by the fire, they were suffocated because the combustion consumed a large amount of oxygen.
At the same time, the rats and cockroaches that lived in the drainage system were also in bad luck. The high temperature forced large numbers of rats to the ground. For a time, swarms of rats roamed the city at night, causing a huge disaster.
But right now, no one cares about rats taking to the streets, leaving swarms of rats running around.
Many people's kitchens and bathrooms first smelled of gasoline, and then changed to a strong burnt smell.
The vast majority of citizens were informed of the burning plan in advance through radio broadcasts and text messages, and did not panic. Instead, they immediately poured tap water prepared in advance into the sewers to prevent the flames from spreading indoors.
Indoor drainage pipes are generally PVC pipes with a diameter of no more than ten centimeters, and the pipelines leading from indoors to sewage wells are basically made of this material.
Even in areas where the water flow failed to suppress the flames, the PVC sewer pipes buried underground quickly melted and destroyed in the high temperature. The collapsed sediment immediately blocked the drainage pipes, preventing the fire from spreading to residential buildings. Only a few buildings broke out in fire.
The fire department, which was well prepared, took action immediately to extinguish the fire as quickly as possible.
Although fully prepared, the burning operation still inevitably caused casualties. However, if the giant ants stranded in the drainage pipelines are not eliminated, even if all the sewage wells are closed, the giant ants can dig a road from the ground to the surface!
