"It's useless. How about transporting people? It's not very efficient. [Read the latest chapter] This car can hold at most 10 people, right?" Wen Desi was not very satisfied.
"It can be used as an armed patrol car!" Wei Aiwen said, "It is equipped with armor on all sides and machine guns on top -"
"Let's wait until the track is laid to Bopu."
"There is a hardened road as the foundation here. If you want to pave it to Bopu, you have to use sleepers and officially lay the track."
"Why not just pave it! Anyway, they are all 1435mm gauge, so there is no waste of repeated construction."
"Let's take it slow. There isn't that much steel to be paved. There are still one or two kilometers of track to be paved in the Bopu factory area - metallurgy and heavy chemical industries are indispensable for the transportation of heavy objects." Ma Qianzhu shook his head. He knew very well that as of yesterday, there were only less than 20 tons of pig iron, wrought iron and steel in stock, and general industrial production could still cope with it. The pig iron shipped from Guangdong will not arrive for another week. I don’t have any iron ore in hand, so I feel panicked. Always importing by sea - now he can understand better than anyone why the Japanese held back their strength and insisted on occupying the Northeast, even if they were beaten to a pulp, they still wanted to hold on to "Manchukuo".
Iron ores and blast furnaces are the foundation of industry. Next, the remote exploration team will conduct special exploration, Ma Qianju thought.
"We also have a modified kit for this kind of self-propelled rickshaw. Chiqi saw that the leaders were not very interested in this kind of rickshaw, so he quickly ordered people to pack the things. Two foldable iron masts were installed on the flatbed vehicle. After entering the track, they would The mast is erected and the sail is pulled up at the same time - the sail is hard and easy to retract and retract. After raising the sail, it is propelled by the wind and assisted in riding, which is naturally much more efficient than simply pedaling.
The advantage of using a hard sail is that it has a high wind-receiving efficiency, and it is very easy to lift and lower. It does not require rigging and has no requirements for maneuvering. It is very practical for flat cars.
"This is still a preliminary design. We have invited professionals who study fluid mechanics to conduct tests in order to obtain the best sail shape. We also want to try whether the efficiency of soft sails is better."
"You don't need to try a soft sail to know that it won't work." Wen Desi was well aware of the advantages and disadvantages of hard sails and soft sails. "You can't solve the rigging problem alone. Do these four people still need to operate the rigging?"
"I never thought about that."
"The wind power resources in Lingao are quite abundant, but even if they are used to drive flat cars, they are still not very useful. Is there any useful power system?"
"Yes, this is a diesel engine. The experimental model uses a single-cylinder engine from Changchai. It works well for pulling flat cars." Li Chiqi pointed to the farthest one. A Changchai single-cylinder engine is placed horizontally at the rear of the flat car. It has a simple gearbox, a joystick, a brake, and a hanger. According to Li Chiqi, it is used to hang lanterns - the light bulbs now belong to "a "Grade industrial materials" are products that cannot be manufactured in a short time.
"If the steam engine can be miniaturized, it can also be equipped with a steam engine. Just increase the strength of the frame. The current materials are still a bit inferior."
"Instead of having to hang a coal tanker, we might as well build a small train." Wen Desi said with a smile - he was also a railway party member at heart.
"What do the leaders think of these vehicles? Should we add more models?"
"The model number is enough for the time being, and we need to grasp the details better." Wen Desi pointed out, "For example, your pedal-powered machine doesn't even have armrests around the four seats, and the diesel engine and transmission are both naked. There’s no protection at all, it’s just a matter of details, and we need to think more about ergonomics – forget it, let’s find a professional to help.”
"That's great." Li Chiqi said, "Mr. Wen, I heard that the executive committee is going to invite craftsmen from Europe?"
"I have this plan." Wen De was stunned for a moment, "What kind of job do you need people for?"
"Yes, yes, it's best to find me a wheelmaker, or you can find one from Guangdong." Li Chiqi has been worrying about this for a long time. Wheelmaking from wood is a very sophisticated craft. Obviously no one is good at Lingao. The wheels of the seized trolleys were very crudely made, and even the roundness was not quite right. Li Chiqi and others now make their own wheels. Although the quality is good, it is probably due to improper craftsmanship. It takes several days to make a wheel, and the product is also quite poor. Many of the vehicles they produce now use rubber cart wheels brought from another time and space.
"Okay, I remember this." Wen Desi said.
"That's the best. If I have enough wheels, I can ride in a sea of carriages." Li Chiqi said excitedly, and showed them 1:2 models of several new carriages he had recently built.
Several models made by Li Chiqi are all very mature freight carriages from the 18th to 19th centuries. There is a very famous Scottish two-wheeled vehicle. This kind of vehicle has a long and large carriage, but it is very light and can be pulled by a horse. Two-wheeled trucks can carry up to 1 ton during short-distance transportation.
There is also a four-wheeled cargo carriage, pulled by two horses, which can carry 3 to 4 tons of cargo. The model Li Chi rode was a Lincoln-style box-type four-wheeler. It has a deep rectangular body with side panels sloping upward. The structure of this car is very simple and suitable for imitation.
"Several major highways are now undergoing surface hardening. Once completed, it will be very convenient to transport materials with four-wheel carriages! A qualitative leap in the history of transportation!"
The four-wheeled carriage is one of the super artifacts for time travellers. But neither Wen Desi nor Ma Qianzhu and others were interested in four-wheeled carriages - in order to conquer the sea of carriages on Hainan Island, you must first conquer the sea of horses. Without horses, there is nothing to talk about.
In their opinion, instead of getting some carriages, it would be more practical to get more light and easy-to-use trolleys - people are much easier to find than horses on Hainan Island, and food is easier than horses.
"You'd better drive more carts." Mei Wan said the truth as soon as she opened her mouth, "There are no horses to pull carts for you now! All the workers on the construction site are shouldering the burden, the efficiency is too low!"
"Yes, yes, I didn't expect this -"
"Okay, it's getting late. Let's take a look at the water supply project." Ma Qianzhu interrupted Li Chiqi's presentation of the design model of the "Russian machine gun carriage" without politeness - although Du Wen wanted to Keep listening.
The next key supporting project is the large-scale water supply system. The original underground water collection pipe system can now only meet the daily water needs of Bairencheng residents - mainly drinking water. Facing the large-scale industrial water use in the future, we will be unable to cope with it.
The scale of large-scale industrial water supply is much larger than that of domestic water supply. The water from the Wenlan River can be used directly to water vegetable gardens or flush toilets, but it is not suitable for use as industrial water. For this purpose, a large water plant must be built.
Simple large-scale water treatment facilities are available in Bopu: a sedimentation tank-sand filter tank is used to purify water quality, which can be used in factories and general life. This method is very simple. Build one or more waterproof masonry pools. Place a 6o-9om sand layer in the pool. The bottom of the sand layer is gravel. The bottom of the pool is a drainage system with gaps between bricks and stones to collect filtered water. Clear water. After the initially precipitated river water fills the pond, it flows through the sand layer between the gravel at a very slow speed, and the solid matter in the water mainly remains on the surface of the sand. This type of pool is simple and easy to implement. The disadvantage is that the filtration rate is pitifully slow. In order to supply enough water, the area of the pool must be increased. Every once in a while, the contaminated surface sand must be cleaned, which is very labor-intensive. In the past, the demand for water supply in Bopu was relatively small, so this problem was not yet prominent. Large-scale use is unacceptable to the Chuan people who are not rich in land and labor.
The difference between this brand-new system and the traditional filter tank is that the water is transported up from the lower part of the sand layer, and an agitator is installed at the upper end of the sand layer. This agitator continuously stirs the sand and assists in the flushing of the upward flowing water. Work. The degree of filtration is greatly accelerated - of course, the filtration effect cannot be compared with the slow sand filter. Fortunately, mechanical filtration systems treat water for purity rather than potability. It is very suitable for time travellers.
"This kind of water can only be used for industrial purposes?" Wu De asked.
"Except for not being drinkable, general domestic water can be treated." Tian Jiujiu said that he, a professional in water supply and drainage, finally started working in this industry.
“Doesn’t that mean we still have to build a new water plant in the future?”
"No need." Tian Jiujiu said, "In fact, just add some basic chemical treatment methods, such as adding alum -"
"Yes, I remembered that in the past, when there was no running water, alum would be put into the tank when the water was brought back. Stir it together and it would be very clean."
"After the chemical industry is established, bleaching powder can be added, or chlorine can be used for disinfection."
"Damn it," Wu De scratched his scalp, "I used to dream about drinking pure natural water. The smell of chlorine made me uncomfortable. Now I can't smell the smell of chlorine, which makes me feel uneasy."
“Where can I find chlorine?”
"Once the electrolytic salt tank in the chemical plant is started, I'm afraid there will be no place to use the chlorine. Just pour it into the water -"
"You want everyone to drink dilute hydrochloric acid. You have to use hypochlorite!"
Everyone laughed.
There is one such system in Bairen Industrial Zone and Bopu Industrial Zone to meet their respective industrial water needs. Tian Jiujiu has set up a steam pumping station at Bairen Power Station and Bobu respectively. In order to improve efficiency and reduce the frequency of sand changes in the filter pool, the river water is pumped up and left to stand in the sedimentation tank for a day or two to allow various larger solid substances to settle. Those identifiable floating objects are manually fished out.
The water treated by the rapid sand filter is stored in the storage tank. The time traveler uses a simple pressure equipment: a steam pump to continuously pump water into a high water tower, using the gravity of the water tower to supply water to the factory.
The new water supply system can be built and used thanks to the better material foundation provided by the traverser's machinery and metallurgical industry: it is the ability to mass-produce boilers, steam engines, and cast various small and medium-diameter water transmission cast iron pipes and valves that make these Basic industrial supporting facilities are possible. ! ~!
