Li Xiang followed Wang Qi's suggestion and used a staggered layout to nail nails into the rock wall.
The problem here is that there is no drill rig that is light enough to drill holes. Li wants to drive the U-shaped steel into the rock wall, which will exert a stress on the rock wall. When the nail layout is consistent with the rock texture, it can easily cause local collapse.
So when she nails, the first step is to check the texture. If it is flat, the U-shaped steel should be inserted diagonally to ensure that the two feet are not on the same line.
The up and down directions should also be staggered to ensure that two adjacent nails are not on the same vertical line, and try to increase the distance between two nails on the same vertical line.
To put it simply, two nails are driven 40 centimeters from left to right and 70 centimeters from top to bottom.
But Li Xiang couldn't finish the entire project because of time constraints, so in addition to two more sets of nails near the top, the distance between each set of nails below was relatively large, with one set almost every ten meters.
She was very efficient. It took three hours, including the time spent by the heavy workers above to put the U-shaped nails in, and they had reached a depth of 500 meters.
When he came up this time, his face, hair, and clothes were all wet, and Wang Qi was helpless.
In fact, with her ability, she could shake off the water on her face and hair with a slight shake of her head, obviously waiting for him to make a move.
Bai Xiaojiao took out the cloak that matched her armor from Bai Xiaojiao's bag, wrapped it around her, and wiped her face with a cloth.
During the past three hours, the magician from the institute was not idle, using magic to strengthen some of the nails.
In addition to bending, the U-shaped steel also has holes on its nail feet for filling with cement to complete the fixation.
The reason why expansion nails are not used is because there is no drilling machine. There is a lack of prefabricated holes and the nail shell of the expansion nails cannot go in. On the shore, you can still use a chisel or a hand drill, but there is no such condition down there. Li Xiang only has two hands and one hand. To fix yourself, you cannot operate more tools.
The effect of using magic reinforcement is the same as using cement grout, but you don't have to wait for it to dry.
The bottom few sets of nails were chosen by Li Xiang to fix them with his own magic.
After completing this part, everyone takes a rest and prepares for others to collect further information.
The crane was also in place to complete the preparation work while Li Xiang was working. When everyone was taking a break, the crane was placing the baskets.
Because the depth is too large and the length of the crane cable is not enough, a set of hoist cranes, that is, manual pulley block spreaders, is needed. This combination is also a tool used by Xincheng for daily crack inspections. The maximum exploration depth is 700 meters, plus the pay-out length of the crane itself. He can only surpass 700 meters, so he can only rely on the magician and Li Xiang in the future.
Wang Qi did not arrange tasks for everyone, leaving it to them to decide below.
Li Xiang acted like a spoiled brat to Wang Qi and brought two magicians, a few measuring tools, and a lot of steel cables down.
The basket went down more than 100 meters and entered the foggy area. The visibility below was very poor. You could only see more than ten meters away by relying on the magic light on the hanging blue. Occasionally, a ghost would pop up and float by. The atmosphere was quite bad. For ordinary workers, The exploration work below cannot be completed at all.
First, go down to 500 meters, hang a steel cable on the last set of pitons that Li Xiang hit, and throw it down directly. Make sure that the pitons can withstand the weight of the basket, and then use the magic communicator to send a signal to pull the basket back.
Log in a set of environmental data and go down with a roll of steel cable and a few pitons.
After repeating twice, the ultimate depth of the crane mechanism is reached.
Repeatedly go up and down from this position to the depth of 500 meters, gather all the steel cables in the 700-meter area, then go up again, bring pulleys and more pitons down.
Because the magic power of ordinary mages is relatively limited, after a few hours, just to protect themselves from high temperatures, a wave of mages were changed.
This time we went down for a longer period of time, and Caroline, who could fly magic, entered the basket together with another senior academician.
Descending to 700 meters, the magic welding work of pulleys and steel cables was completed. The senior academician used levitation to maintain the hanging basket, and Li Xiang was responsible for transferring and fixing the joints of the hanging basket.
After completion, throw the extra steel cable into the hanging basket, and then it comes to the manual operation stage. At this time, Li Xiang himself is the crane,
This job is very difficult, because you cannot pull one steel cable alone. You must pull both the ascending and descending steel cables passing through the pulley at the same time to prevent people from being pulled out.
Of course, this is nothing to Li Xiang.
As the ropeway continued to descend, Caroline stared at the thermometer and barometer, mentally calculating the altitude, and said from time to time: "Your Highness, make a hole here."
At this time, Li Xiang would hold the two steel cables together with one hand, and then use a short spear to make a hole to measure the temperature inside the rock wall.
There is no need to check the humidity during the whole process, because when the humidity is below 100%, the mist will gradually turn into water vapor and merge into the air. The persistence of the mist is one of the characteristics of 100% humidity.
The only work that needs to be done to measure the humidity does not need to be done here. He only takes a small amount of samples from the small holes that Li Xiang made, and puts them in containers the size of earring boxes to analyze the moisture content after returning.
Relying on a pulley mechanism composed of two steel cables, the three people descended to a depth of 900 meters in a basket.
With a cracking sound from the card, Caroline became a little nervous: "The alcohol thermometer exploded."
The measuring range of the thermometer is determined by the purpose, and is not necessarily the boiling point of the indicator. The upper limit of the cracking temperature is 60 degrees, which is used by the exploration team for geological exploration.
Caroline took out another one. This one is a magic thermometer. It is used for magic experiments in the courtyard. It measures the size change of a piece of special alloy. The maximum withstand temperature can reach 1,300 degrees. The disadvantage is that the accuracy is very poor and the lowest range is It is a division of five degrees Celsius, so it is useless in the front.
Wang Qi said that at this stage, Li wanted to listen to the two academicians.
"Are you still going down?"
Caroline asked another academician: "Does Lao Ai still have enough magic power?"
Lao Ai is responsible for protecting himself and Caroline's body surface temperature, but the actual method is to maintain the temperature and humidity of a part of the entire basket, so as to protect the lungs and ensure that the measurement work is not affected, which is actually quite troublesome.
"It's okay. As long as the temperature change isn't too big, another hour should be enough."
"Then please prepare to continue, Your Highness."
Li Xiang said nothing and continued to put out the line, and soon reached the bottom of the pulley ropeway, one thousand meters away.
He took out the pitons from the basket and hammered them into the wall. Thread the remaining steel cable through it and connect the ends. Then, Caroline cast the floating magic to complete the pulley transfer.
The main purpose of this is to prevent the basket from falling too far when it loses control.
There are various reasons for losing control, such as encountering enemies, etc., and there may be situations where three people cannot be taken care of, so the basket needs to have a certain limit to prevent people from being put too deep to get back.
Although Li Xiang could jump up there, it was not necessarily possible to catch two people.
In short, create a new anchor point here and continue lowering the basket.
Further down, the outside can no longer be called water vapor, but can be called sticky.
When it reaches the bottom, the temperature reaches 80 degrees. Due to the accuracy of the measurement range, there may be an error of two to three degrees.
There was nothing left for Li Xiang to do next. Lao Ai used the enchantment spell to protect Caroline, and Caroline directly used the flying spell to detect it.
The flying spell consumes a lot of magic power compared to the human body and cannot last long, so it must be started at a deep enough place to ensure a large enough detection depth.
About three minutes later, Caroline flew back and signaled that she could go up.
Going up was more difficult than going down. Li Xiang had to expend about 30% of his strength in standard mode to lift three people up together with the basket.
When they got to the ground, the three of them were as if they had been fished out of the water.
