After crossing this relatively wide river, we waded through several shallower rivers before reaching the mountainous area. There are several tunnels dug in the mountains, but some of them are in disrepair and have collapsed underneath.
The width of the tunnel can accommodate two vehicles traveling in parallel, and it is still possible for a vehicle to pass through it. However, some vehicles are too large and need to be modified, that is, the parts on both sides are removed and then changed into slender ones.
In addition, the wheels need to be changed so that they can be stuck on the lower left and lower right sides to support the entire vehicle moving forward.
“How were these tunnels built?”
"First, set up the arch frame of the cave door according to the designed position, then pour concrete, drive the steel pipe into the large pipe shed, and then inject cement slurry into it under high pressure. The advantage is that the soil sticks to the cement slurry on the steel pipe. They tie together to form an arch-shaped reinforced soil body. They will not collapse easily when digging."
"It's time to dig a tunnel. Different methods are chosen based on the quality of the rock. The size and method of digging are different. If it is hard and complete rock, the tunnel can be dug as large as it is. If it is soil, it will be divided into three or four pieces, etc. Dig. Generally speaking, rock tunnels will not collapse immediately after being dug, and earth tunnels will not collapse immediately due to pre-grouting or thicker steel bars. At this time, workers will follow the measurement instructions to make the pre-made tunnels. The steel arch frame that looks like the outline of the tunnel is placed at the designated position. After the steel arch frame is placed, steel mesh pieces must be placed in the gaps between the two arch frames, welded well, and anchor rods must be driven into the sides. Then, Concrete needs to be sprayed. After the concrete is sprayed, it will stick to the steel frame, so that the steel frame and the rock and concrete of the tunnel form a whole to bear the force together."
They started to modify it. While discussing the location of the car thief.
"They should be not far behind us. We must pass through these caves as soon as possible. If we let them catch up and they block the caves, it will be difficult for us to pass."
"They may have sent some cars to block the cave first, so we have to speed up the progress."
There was a car building some distance behind Qi Yanliang and others. "We have bypassed the ravine and the river. We should be faster than them. Why can't we see their traces from behind?"
Pi said: "Our speed is already fast enough. There are more of them, so the speed should be slower. Let's get to the mountainous area ahead as soon as possible, block those caves, and intercept them all."
Shu said: "It's too far. I don't know if they have any other way to cross the natural chasm or the river."
Pi said: "There should be no other way. It is impossible for them to build the bridge on site. Even if they build the bridge, it will probably take several months."
Shuxue said: "Okay, let's head towards the cave in the mountainous area quickly."
Dai Zhao, Zheng Xiling, Qi Yanliang and others took the time to modify several large construction vehicles. The relatively small construction vehicles in front had already entered the cave. In some places in front, the top collapsed, and the fallen stones were pushed away with bulldozers. In some places, the bottom collapsed, so wheels with supporting functions were used to support the lower left and lower right corners, and they were set up to build a vehicle to move forward.
They quickly passed through the cave in the mountainous area and reached the sandy area ahead.
The car thieves arrived at the cave area and waited for a long time, but did not find Dai Zhao and the others. Later, looking at the wheel marks on the ground, I realized that Dai Zhao had reached the mountainous area before them and should be in front of them now. How is this possible? How did they pass through the ravines, how did they pass through the rivers, and how did the large-scale construction vehicles pass through these caves?
They are already accustomed to using inherent thinking to evaluate themselves and others, and they underestimate people's initiative. Underestimating one's own initiative, and then escaping from it, underestimating the initiative of others, and underestimating the abilities of others.
"We can't wait any longer. Let's move forward quickly. We'll use cars to intercept some construction vehicles first," said Shu.
On the long and narrow road, several modified cars belonging to the car thieves were running at high speed and started a chase with large construction vehicles. Dai Zhao left a construction truck to intercept the car thief. That is to say, Dai Zhao first seized several parked cars, and then the car thieves took back another parked car. Dai Zhao, Qi Yanliang and others still need to continue to regain control of the car construction.
He Yushen stayed in Gui's car, reading computer information and looking for their travel plan.
Group B in the car theft took away part of the built car and told Group A to assemble at the designated location. However, due to He Yushen and others, they have deviated from the planned track. He Yushen wanted to quietly take away the ignition key, but the car thieves still surrounded him and the patrol team had not arrived yet. The structure of the Zhuqi has been figured out clearly, that is to say, what kind of building is this Zhuqi converted into and what is the room setting like. Several construction vehicles have changed their paths and moved south. It also delays car theft. Other construction vehicles circled around again before arriving at the designated location, which was very close to the danger zone. The car thief thought that when they arrived and stationed themselves here, others would not approach them easily.
Dai Zhao, Qi Yanliang and others quietly approached the car robbers' temporary camp and arrived near the car robbers' car building position. In the evening, the car building has begun to change its shape.
The next plan is to secretly start the vehicle transformation at night and leave this place. The construction truck moves very slowly, so part of it can only be moved away first to avoid alerting the enemy.
The top of a building carriage is opened, the walls and floors are gradually erected, and the stairs are gradually lifted from both sides and released from the folded state. office building.

There were some metal plates on the ground, and the boy asked, "What are these used for?"
Dai Zhao said that this is a prefabricated ribbed base plate, which is composed of a solid flat plate and ribs with reserved holes. It is prefabricated and used as the base plate of concrete composite floors. The prefabricated ribbed base plate serves as a permanent formwork for the layup and carries the construction loads. Since the longitudinal stress-bearing steel bars can be prestressed or non-prestressed, prefabricated ribbed bottom plates are divided into prefabricated prestressed ribbed bottom plates and prefabricated non-prestressed ribbed bottom plates.
When changing the settings, just set the vehicle to arrive at the predetermined location and leave after one night. Now it seems that car building is changing its shape. Many of the prefabricated ribbed base panels were taken out, unfolded, folded, and assembled. You should be able to take advantage of it. While a lot of materials for car construction were taken out, several construction cars drove away at this time, so they shouldn't be discovered soon.
