Originally, according to the plan of the regiment, the first two days were to dig a trench, and the next two days were to lay optical cables, backfill them, and bury markers. Pen, fun, and www.biquge.info

However, this is the ideal state when planning is made. In the excavation process, due to different geological conditions, it is common for the construction period to be unable to be completed on time. As soon as it encountered complex terrain such as mountains, rivers, and rocky areas, the construction period had to be postponed.

No, it's a problem today.

Today the missile is connected to the task of excavating three hundred meters.

After receiving the task, everyone began to feel that the amount of tasks today was so small that they should be able to complete it ahead of schedule, but after going to the site to investigate, everyone was dumbfounded.

It turned out that today's construction site is crossing the river.

The river, about 100 meters wide, is flanked on both sides by a riverbed, and extends about 100 meters out from north to south. The geological conditions on both sides of the riverbed are better, and they are basically the soil of the field. But the construction in the middle of the river is more difficult.

Because there is water in the middle of the river. The depth of the water is about 0.3 meters, not too deep for a person to be able to wade through, but. Everyone is not clear about the geological conditions under the riverbed, is it silt, sand, or rock under the river? How to excavate more scientifically?

The company commander left the task, the difficult task to a platoon, to dig the river channel. The extension of more than 200 meters on both sides of the river was left to the second row.

After receiving the task, Yang Wenbin felt difficult at first.

But he thought that since the construction and design of this road, there must still be a way, and put the squad leaders and old volunteers. Gather together and study how to excavate more reasonably.

Zhou Dejun put forward his idea, he felt that it should be dug from both sides to the middle, for example, the first shift dug from the south bank of the river to the north bank, and the second shift dug from the north bank to the south bank of the river, and the two ends went hand in hand. The three shifts were dismantled and strengthened to the first and third shifts.

Zhang Shuiquan came up with an idea, he said, the construction in the river must be greatly affected by the river, considering the depth of the river, it is not very deep and relatively wide, and the water flow is slow.

It should be done by digging an aqueduct on the side of the embankment to divert the river from the side and then excavating. Although the amount of earthwork in the early stage will be very large, it will greatly improve the efficiency of construction in the water in the later stage.

Yang Wenbin also preferred Zhang Shuiquan's plan, that is, to intercept the flow in sections first, and then carry out construction. Intercept a section of construction to ensure efficiency.

Wang Shiquan also supported it, and everyone leaned towards Zhang Shuiquan's plan.

Yang Wenbin reported the platoon's construction plan to the company commander. The company commander listened to Yang Wenbin's report. I felt that Zhang Shuiquan's plan was usable and the most efficient, so I approved it.

Once the plan is decided, all that remains is implementation.

Yang Wenbin, the division of labor for the excavation work.

According to the regional conditions, it is more convenient to intercept the flow in the excavation guidance area on the north bank of the river. Specifically, the second shift is responsible for the work of excavating the pilot channel. On the north side of the river, a diversion canal with a width of about 10 meters and a height of about 1.5 meters was excavated!

Once completed, two gaps will be opened in the upstream and downstream of the dam to divert water from the diversion channel downstream.

The third shift is responsible for preparing several woven bags, filling the pockets with sand, and then starting to stack them from north to south, one bag after another, to block the river water coming downstream.

The first shift is responsible for excavating the fiber optic cable trench downstream of the sandbags on the river surface that intercepts the flow.

After making up their minds, each class returns to each class and begins to work according to their specific tasks.

Although the weather was cold, all classes took off their cotton shoes, put on rubber shoes, and prepared to excavate.

Zhou Dejun took the lead in taking off his coat and wearing only a vest, revealing the white flesh inside. He led the soldiers of his squad and began to dig.

The most naughty cypress pine is now the main force of work. He picked up the shovel, kicked it with his left foot, stepped the spade into the soil, and then, with both hands, shoveled up the soil layer with all his might, and lifted it into the line of the embankment next to it.

In this way, he dug with a spade and shovel, each time he could sink the spade surface into the ground and scoop up as much soil as he could.

The other little warriors often went down with a spade, and could only shovel up half a shovel of soil.

There's skill, there's proficiency, there's also strength.

Su Zhijian, Liu Jun, and Li Yang, following the example of Bai Song and Zhou Dejun, dug hard behind them.

The third shift is packed with sand in woven bags, and the embankment is laid from the inside of the embankment to the river.

Wang Shiquan, at this time, gave full play to the exemplary and leading role of the backbone of the squad leader. He threw off his arms, wore only his vest, took the lead in filling the woven bag with sand, carried it, and strode towards the inner side of the embankment, stacking the sandbags into the water.

Wang Shijun did not show weakness, and the second, carrying a sandbag full of sand, followed Wang Shiquan, and rushed away.

The power of example is endless.

Gao Dalong, Xu Liang, Huo Hua, and Li Kui, these little soldiers, did not show weakness, followed the example of the squad leader, carried sandbags full of sand, and ran towards the inside of the river.

Three shifts are lined up. After putting the sandbags into the water, the river slowed down significantly.

Then, one shift. According to the standards specified by the technicians, a two-meter-deep fiber optic cable trench was excavated from the inside of the embankment.

The task of the first class seems to be very heavy, but because of the geological conditions at the bottom of the river, it is different from the loose soil type on the ground.

The first layer below the bottom of the river is silt, the second layer is river sand, and the third layer is rock. Therefore, if you don't dig through the third layer, you can't reach a distance of two meters.

Zhang Shuiquan, after assigning the task, also rolled up his sleeves and began to work. Li Yan, Sha Haitao, Ren Chengwei, and Wang Feng, not to be left behind, also picked up shovels and started working.

Yang Wenbin, who made a mistake between the first, second, and third classes, guided the actions of each class, and worked for a while wherever he needed a hand.

Where there is a need to adjust forces, he gives specific advice. The fighters adjusted according to his opinion.

In the beginning, everyone was wearing training uniforms and velvet jackets underneath. But the drier it gets, the hotter it gets, the hotter it gets, and later, everyone takes off their shirts, and even, only the vests are left, and it's still sweating like rain.

So, after three hours of fighting, it was almost time for lunch. The embankment of the second shift is finally complete! And the third shift, the protective sandbag wall, was also completed about fifty meters. In the first shift of the optical cable trench, he dug wherever the protective wall of the third shift was stacked. However, in terms of depth, it did not meet the requirements of construction, because it was filled with water immediately after digging. Very bad for the job.

Seeing that the second class had completed the task of guiding the canal, Yang Wenbin clapped his hands. The first squad leader and the third squad leader were called.

He asked the three classes to work together. In the first and third shifts, the downstream diversion was excavated and two meters were dug out.

"In this way, the outlet of the diversion canal is opened first, and then the upstream inlet is opened to direct the water from the upstream."

As soon as the words fell, everyone picked up their shovels and pickaxes and started working.

Within half an hour, the inlet and outlet were dug through.

Because the river is blocked by sandbags, the river water follows the diversion canal, enters through the inlet and exits through the outlet.

In this way, the water level in the river slowly drops, revealing the bottom surface of the riverbed.

Then Yang Wenbin coordinated the second class and joined the ranks of the third class and the first class.

The comrades of the first and second classes should pay close attention to digging the fiber optic cable trench.

The structure at the bottom of the riverbed is completely different from that on the ground, and there is about 10 centimeters of silt on the top of the riverbed. Further down, there is sand, about 20 centimeters thick, and digging further down, there is a layer of pebbles.

It is becoming more and more difficult to dig fiber optic cable trenches.

And after a morning of hard work, everyone is exhausted.

At this time, the cooking class brought the food.

The company commander gave the order to start eating first and continue construction after lunch.
