This set of combined Luoyang shovel, not only made very exquisitely, but also designed very reasonable, in addition to the parts of Luoyang shovel, there are two independent parts.

One is a striking pad for hitting the shovel downwards, and the other is a reverse hitting pad for lifting the shovel upwards. The main function of these two hitting pads is to pad on the top of the Luoyang shovel, so that when the shovel is smashed down with a hammer, the threads in the steel pipe will not be damaged.

The hitting pad used when the shovel is a thick iron sheet, which is welded with a small steel column slightly finer than the inner diameter of the steel pipe, when in use, as long as the steel column is inserted into the pipe, and then hit the iron sheet hard, the Luoyang shovel will go deep into the soil under the force of the impact.

When the tip of the shovel is about to fall into the soil, remove this striking pad, then connect another steel pipe, then put in the hitting point, continue to smash down, and then connect another steel pipe. As long as there is a steel pipe, theoretically speaking, this shovel can go all the way deep into the soil.

When lifting the shovel upwards, the striking pad used is similar to this, but the small steel column welded on it is threaded, which can fit the inner diameter of the steel pipe exactly. When in use, as long as the steel column is inserted into the steel pipe, the thread is tightened, and then the hammer is struck upward, and the Luoyang shovel, which is nailed to a depth of several meters in the soil, will rise up little by little with the hammer.

After the whole steel pipe is completely off the ground, carefully remove the steel pipe, screw the upward hitting point on the steel pipe below, and hit it upwards again. The Luoyang shovel buried in the soil will be lifted out little by little.

After trying to combine the various parts of the Luoyang shovel together and studying the general use of this combined Luoyang shovel, Chen Ziyang jumped into the three-meter-deep soil pit he had dug before with a few steel pipes and hitting pads.

The location of this pit is probably in the center of the entire collapsed area, and this is the place where Chen Ziyang has selected to dig the thief hole before, and it is most suitable to place the first shovel here.

Li Bojian stood next to the big pit and helped Chen Ziyang hand him other steel pipes. Originally, Chen Ziyang was full of confidence in the place he chose, but when the tenth steel pipe was knocked into the soil, Chen Ziyang couldn't feel his pulse a little, this tomb couldn't be so deep!

Ten steel pipes plus the shovel head of the Luoyang shovel is already eleven meters away, plus the three-meter-deep pit he dug before, that is to say, the current shovel head has reached a position of fourteen meters below the surface.

Although Chen Ziyang thought that this tomb was very likely to be deep below the surface, the depth of fourteen meters was a bit too exaggerated, and with suspicion, Chen Ziyang nailed three more steel pipes.

At a distance of seventeen meters, when hitting the Luoyang shovel, Chen Ziyang could feel that the lower the blow, the greater the strength required, that is to say, the tip of the Luoyang shovel was always in the soil and was not inserted into a certain space underground.

No need to smash down again, there must be no tomb below, Chen Ziyang had a trace of loss, and then he bit by little he nailed into the Luoyang shovel and came out again, every time he took out a section of steel pipe from the soil, Chen Ziyang carefully unloaded the steel pipe to prevent too much loss of the soil preserved in the center of the steel pipe, and put these steel pipes at his feet in the order in which they came out.

On the side of each steel pipe, there is a small section of tempered glass, which almost runs through the body of the steel pipe, and from here you can directly see the appearance of the soil preserved in the center of the steel pipe.

After the Luoyang shovel was completely lifted, the first thing Chen Ziyang checked was the soil stored in the shovel head of the Luoyang shovel. The soil in the shovel head is very normal, there is nothing else mixed in, and there is nothing special about the soil in the middle except for a little wetness.

So Chen Ziyang looked at all the soil preserved in the other Luoyang shovels, and compared them one by one in order, probably at the eighth rigid pipe, there was an obvious separation of soil layers. Comparing the soil above with the soil below, it can be found that the soil above is significantly less dense and has more crevices, while the soil below is more compact.

Seeing this obvious separation of soil layers, Chen Ziyang knew that he had guessed correctly before, and the height of the backfill should be more than ten meters away, that is, the soil below had not been passive. It's really strange that the location of this pit should be in the center of the backfill area, why is there no tomb underneath?

After thinking about it for a long time, Chen Ziyang patted his head, he was really confused! How could such a large excavation of an underground mausoleum be carried out directly above the tomb? They should be digging the door of the tomb, or one side of the tomb road.

That is, the place where the mausoleum can really be accessed should be at the edge of this backfill area, and not in the very center. This huge backfill area was supposed to be used for storing equipment or personnel turnover, and if you really want to probe the edge of this tomb, you must look for it at the edge of the backfill area.

Thinking about this, Chen Ziyang kicked and shaved all the soil in the Luoyang shovel, returned to the ground with the empty steel pipe and shovel head, and after carefully observing the surrounding environment again, Chen Ziyang selected several other locations for the Luoyang shovel.

With the previous experience of using the Luoyang shovel, coupled with the approximate prediction of the depth of this tomb, Chen Ziyang used this Luoyang shovel again, it can be said that it is handy, every time he smashed into the twelve steel pipes, Chen Ziyang will get the shovel out, and then carefully inspect the soil inside.

Two more shovels were lowered in succession, and Chen Ziyang didn't find anything until he hit the Luoyang shovel at the third selected shovel location, when he went down with a hammer, and suddenly felt that the shovel had dropped a little more. The feeling from the hammer told Chen Ziyang that the Luoyang shovel should have entered a space underground.

He smashed two hammers at the root of this steel pipe again, Chen Ziyang obviously felt that the two hammers were as big as the force used before, but the speed of the shovel was obviously much faster, so Chen Ziyang Yang quickly shoveled Luoyang out and carefully inspected the soil inside.

There is no soil in the last section of the steel pipe, and there is only half a pipe of soil in the penultimate section of the steel pipe, it seems that there is no mistake in my guess, and there is indeed a space below.
