After reaching the ice sheet, first of all, the soldiers of the Naval Engineering Brigade landed on the shore first, and they were not in a hurry to start breaking the ice, but first ran around pulling ropes on the ice. Old Liu Tou and Chen Hui looked at it for a while and didn't see the famous hall, but there was a dun ding next to them who said, "They didn't open a way on the ice, right?" ”

Being reminded by the dunding like this, Lao Liu Tou suddenly understood that these soldiers in blue uniforms running around with ropes were not running around without rules at the moment, but were marching in their direction according to a road that was fifty zhang wide, and about every time they walked more than a zhang distance, those soldiers would make a mark on the ice sheet. The soldier with a long iron rod in his hand took the iron rod and began to punch holes in the ice sheet, leaving a mark.

In the distance, the ship, which was spewing black and white smoke at the same time, drove towards this direction, slowing down and turning its hull sideways as it approached the ice cap. At this time, the people on the pier saw that the boat was not only very wide, but also very long, at least more than twenty zhang long. The ship was converted from a large ship, but her modification was different from the ordinary ship, which was usually only a small modification, the ship itself was a ship that had been enlarged in construction, and the displacement had already reached about 500 tons, and after the shipyard dragged it onto the slipway, it first raised the ship's freeboard, then carried out an almost reborn widening, and then installed a steam engine at the amidship of the hull to drive the propellers installed on both sides of the hull. The ship had nearly fifteen different enclosed compartments, and after improvements by the Senate shipyard, her mast was largely cut off, a six-metre-high bridge was added to the upper part of the steam engine power room, and all the mechanical operation of the ship was introduced into the cockpit on the third level of the bridge with transmission equipment.

After the end of the enmity, the cold and the fight of the solitary

The original mast position next to the bridge has been replaced by a medium-sized crane, which is made entirely of steel, and in order to make it work, the crane has also taken considerable painstaking work from the design department to install a complete set of beam base at the position of the hull to lower the center of gravity and ensure that it does not break when lifting work. The three compartments at the stern of the hull are used as coal bunkers, combustion chambers and water bunkers, while the front compartments are mainly cargo compartments for carrying cargo that can be lifted quickly.

This improved version of the steam-powered Canton was part of the Daihatsu Yacht Renovation Project that the Senate had originally intended to promote on a large scale, but the technical department sealed the project after the modification and production of two Daihatsu boats of the same type. The reason is simple, this kind of big hair boat modification is too cumbersome. In the process of renovating this large hair boat project, it is first necessary to completely remove everything above the hull deck, and there can be no sail cables left, and then lift the deck completely, and carry out large-scale installation of steam engines and boilers in it, and at the same time, screw thrusters and transmission mechanisms must be hung on both sides of the stern. After making these modifications, the hull must also be widened and heightened, and then the crane is erected, and finally the driving mechanical transmission mechanism can be completed to install the bridge, not only the process is complex, the requirements for mechanical equipment are also very high, in the improvement of these two large hair boats, many equipment and even the cabin body was dismantled and demolished, and it was completed several times, originally these were intended to be used for inland river transport ships near the Pearl River Estuary, and the slipway on the two free ships at the same time. As a result, the freewheels from scratch have completed the launching ceremony, and the two daihatsu boats have only completed their outfitting. After a trade-off between the technical department and the industrial department, the Guangzhou Shipyard Dafa Yacht Renovation Project was finally mothballed, and except for the two that had already been launched, the other Guangzhou Ships continued to use wind power as power for the time being.

Both Daihatsu boats have arrived in Qingdao with the northbound brigade, and the "Daihatsu-A" has already heated up its boilers and started working, while the "Daihatsu-B" is still loading cargo on the other side of the Dongfanggang while waiting for the boiler to heat up.

The crane of the ship A began to make a metallic twisting sound, and the driver, dressed in a thick cotton coat, wearing cotton gloves in his hands, and wearing goggles in his eyes, drove the crane arm to work on the top of the crane, lifting one after another of the barns out of the cargo hold and placing them in the places indicated by the soldiers on the ice.

The knot is far away, and the monthly exam of the ghost ship school is early

The soldiers waited for the crane to put the shelves in place, and then they rushed up and took out a lot of tools from the first barn, including small carts, which had no wheels on them, and some were just sleds, which were used to quickly transport goods on the ice.

"A little left! A little left! The soldier in charge of the command on the ice waved his hands vigorously and shouted loudly at the same time, "All right! Put! Put! Slow down! The steel cable in front of the boom was slowly released, and the next silo board hanging from the hook was slowly placed on the ice sheet. The soldiers stepped forward and laid the wooden planks in front of the partition door, then opened the partition door, only to see a large pile of black things tumbling out. One of the dunding squinted his eyes for a long time, and then said with some hesitation, "It seems to be coal in it." ”

It was indeed coal in the slab, but the Naval Engineering Brigade did not intend to burn coal on the ice to thaw it, and soon the soldier in charge of the survey shouted, "Fifty meters completed!" This section to the sea water position is all used to break the ice manually! The soldiers who were waiting next to them hurriedly rushed forward and dug hard at the location marked by the colored flags before.

Their method of breaking the ice is to use an iron pickaxe or steel drill to make holes in the ice every meter or so, and then use a large or small hair boat to drop anchor and directly pull out the broken ice into pieces. Such work went smoothly at first, but at the beginning of the twenty meters it slowed down. However, this did not bother the soldiers of the engineering brigade, who pulled the ice floes that had been dragged out directly onto the Dafa boat, and then sent them to the pre-prepared tanks in the combustion chamber, where the ice was quickly turned into water and then heated to about 50 degrees Celsius. The hot water in the tank of more than 50 degrees is sprayed directly with a canvas water pipe through the pumping machine, so that the ice that needs to be broken quickly melts quickly, and the speed of ice breaking is accelerated very quickly.

The enemy is not a party, and the ship is connected to the ground

These sea-borne ices are not salt water, they are solidified by fresh water, and the freezing point of salt water is much lower than the temperature of pure water, and the higher the salt content, the lower the freezing point. When there is a freeze at sea, the first thing to condense is fresh water, and when it freezes nearby, the salt is removed and the sea freezes physically. However, this ice water cannot be used as boiler water, because the ice is uneven when it freezes, and in many cases it may contain a small amount of seawater, which not only contains salt, but also has a much higher concentration, so it cannot be used as boiler water.

I watched the soldiers in the distance dragging canvas water pipes walking on the ice, and the hot water sprinkled on the ice sheet suddenly vaporized, like a fairyland. The people on the pier platform were dumbfounded, these are all hot water! It's just a tyrannical thing! Now, when it is so cold that it can directly freeze the birds to death, there is still a lot of hot water poured into the sea and ice, which is too luxurious. However, the effect of this ice-breaking method is very obvious, and in just over ten minutes, the soldiers of the Naval Engineering Brigade directly advanced the length of the ice-breaking to a position of about 100 meters above the sea line.

The thickness of the next ice layer has reached more than one meter, and the possibility of breaking the ice with hot water is already very low, and the naturalized civilian officer in charge of the command looked up at the sky, although it is still windy, but the sun in the sky is still quite large, the only thing that makes people uncomfortable is that the sun finally feels a little heat on the body and is immediately ruthlessly blown away by the sea breeze. "Ready to scatter coal!"

Hong Jie was also on the ice sheet at the moment, he didn't need to go ashore, these things were basically done by the naval engineering team. But he just couldn't sit idle, and at the moment he was running back and forth on the ice in a pair of large "snow boots" with wide soles, checking the location of the holes in the ice and whether the soldiers' operations were dangerous. As a native of Xi'an, he has a lot of knowledge about ice and snow, so it is for the same reason that he was sent to the northbound brigade. "Be careful, this position has been opened, beware of the ice sheet cracking!"

The soldiers pushing the carts walked back and forth on the ice, pushing carts of coal to the predetermined place to unload the carts, and then the soldiers waiting next to them stepped forward and spread the coals with shovels in the predetermined area, and in a short time, from the unloading point to the predetermined landing ice area, it was already paved into a rectangular area 50 meters wide and 100 meters long.

Hong Jie took out the same huge pocket watch from his pocket, looked at it, but the second hand was motionless, and then he remembered that he had forgotten to wind it in the morning, and couldn't help but sigh and turn to a naturalized officer not far away, the officer also held a shovel in his hand, and was spreading the coal pile on the ice surface. "Hey! Who's that! What time is it? Hong Jie shouted loudly.

The enemy and the enemy are enemies and ghosts, and the post is cold

The officer was stunned for a moment, but when he raised his head, he found that it was a veteran officer with a veteran sleeve on his cuffs, and hurriedly wanted to stand upright, but was stopped by Hong Jie, "It's okay, it's okay, it's in the red zone now, you can help me see what time it is!" ”

The officer hurriedly pulled out the pocket watch from his pocket, but in a hurry, he didn't grab it, and the pocket watch slid all the way down the glove, and fell to the ice with a scream. This kind of pocket watch is not big, but it is absolutely not falling, and most of the parts inside are made of steel, but due to the complex and precise structure, once it is hit hard, it is likely to be ineffective or even stop directly. Not to mention the glass cover of the pocket watch, as long as it falls to the ground, it will definitely crack, and the glass factory has no way to temper such a small glass at the moment. Therefore, once this pocket watch falls to the ground, the only consequence must be that it is broken and unusable, and the pocket watch is issued by the Senate to officers to keep track of time, and the cost of such a watch is completely more than a new rifle and binoculars, so it is impossible to equip every soldier, even an officer must be a lieutenant or above before it can be issued, and having a pocket watch in the army is basically a status symbol. If his pocket watch is damaged by a fall, there is absolutely no way to repair it in a short time, so the precision equipment of the machine must be sent back to the Dongfanggang Hardware Factory for repair.

The enemy of the distant land hated the sun, so it was secret

The pocket watch fell into the air, but a white figure pounced, slid over a pile of coal, stretched out a thick cotton glove, and caught the pocket watch in the air. The officer, who was frightened into a cold sweat, hurriedly looked carefully, it turned out that the person who caught the pocket watch was a special detective team, this person got up nonchalantly, handed the pocket watch back to him and said, "Pay attention, comrade, this is the property of the Senate, if you lose it, it will be unlucky." With that, he turned and left.

"Nine thirty-five, chief!" The officer hurriedly looked at the pocket watch, reported to Hong Jie, and then carefully put the pocket watch back in his pocket. Hong Jie also knew that he was scared enough, so he didn't say more, and hurriedly wound his pocket watch and set the time. At 9:35 p.m., the sun is at its strongest, and between noon and around 3 p.m., the sun will reach its strongest. When the sun hits the coal, the heat will be absorbed by the black coal, and then used to melt the ice sheet covered by the coal, and when the thickness is reduced to about one meter, the Daihatsu boat will come and wash the ice passage with hot water, and you can quickly open a passage in the ice here. After the passage was opened, the soldiers would clean and dredge the ice floe inside, and then let the bison transport truck on the Port Vostochny land from the water, and then build a floating trestle directly on it to ensure the rapid unloading of supplies.

This special investigator is Lan Xiaoya, after their detachment hurriedly located the unloading point in the morning, he has always felt that something is not quite right, you must know that when they first landed, they started to measure from the boundary between the ice sheet and the sea water, but in the morning, because they were in a hurry, they could only find the nearby ice and snow covered area at random for punching and measurement, so it is likely that there will be different ice thicknesses, and even when punching holes, several places even directly punched out the sand. Therefore, after consulting Yang Muqin, he patrolled back and forth around several punching points to see if there was any calculation error, and when he saw a soldier with punching holes, he would also ask them to punch a few more holes nearby to see the average thickness, and when he arrived here, he happened to encounter the pocket watch and fell down, and he was saved in mid-air.

"Nine-thirty-five, chief!" The officer hurriedly looked at the pocket watch, reported to Hong Jie, and then carefully put the pocket watch back in his pocket. Hong Jie also knew that he was scared enough, so he didn't say more, and hurriedly wound his pocket watch and set the time. At 9:35 p.m., the sun is at its strongest, and between noon and around 3 p.m., the sun will reach its strongest.
