“Even if the drainage fails, floods raging on these flood control bridges can also prevent floods.”
Soon, they established the location of the flood control bridge upstream of the river. Not only that, they also planned a lake location near the river to be used as a reservoir.
When the flood is raging, after passing the flood control bridge, it will turn into a gentle stream and flow into these reservoirs. After the water in these reservoirs is full, it will pass through the river and reach the sea.
First of all, they must first dig a huge reservoir, which is a man-made lake.
But you must know that now this white cloud lord Bianke is all ground made of a mixture of 70% ice and 30% soil.

In the previous ice age, the soil was covered with a layer of ice and snow. They only needed to throw away the ice and snow to see the true face of the soil.
But now it’s different. After soaking in the flood, the water has fully entered the ground and mixed with the soil.(Read more @ wuxiax.com)
With the advent of extreme cold, the water in these soils also began to freeze and mix with the soil to become frozen soil.
Although the hardness of these frozen soils is not as hard as steel, it is also similar to stone, so their construction difficulty has risen again.
Workers from the Ministry of Engineering took the lead in planning the area of the new reservoir on the ground. They first used a laser mapping device to plan the construction route of the reservoir on the frozen soil.
Then they adopted the most violent construction method, which was to first use bombs to blast the ground, and then further repair the ground after the explosion to shape it into the shape they wanted.
With a loud noise, I saw those geothermal bombs exploded on the ground, and the ground was blown into pits.
Then workers from the Ministry of Engineering of these countries began to use tools to plan ramps around the reservoir that can be accessed by excavators.
Today’s excavators have also been transformed. Some heating plates are used inside the excavators for heating. Only in this way can they dig on the frozen soil.
If you want to excavate the ground, you must first completely thaw the moisture in the frozen soil. Otherwise, the frozen soil will be as hard as a rock, which will cause huge damage to the construction equipment.
After heating, thawing and digging, and after a series of operations, the whole project began to formally progress. It took them a whole week to create this man-made lake, just right.
They also reinforced this man-made lake to make it a real reservoir. Not only that, but also added some observation tests at the bottom of it to observe the changes in the water volume in this reservoir in real time.
Then, the flood control bridge was built above the reservoir. First, they had to build the foundation for the supporting structure of the flood control bridge.
This requires them to start excavating accurately on the ground. They cannot use geothermal bombs for bombing. The damage of geothermal bombs is too great. Once they explode, the pits that appear may be far larger than the diameter they need.
Therefore, they can only use the drill bit, a precision engineering device, to build the foundation. .
