Chapter 233 Supporting Facilities

"It's useless, how about transporting people? The efficiency is not very high. This car can hold up to 10 people, right?" Wen Desi was not very satisfied.

"It can be used as an armed patrol car!" Wei Aiwen said, "Armor is installed on all four sides, and a machine gun is mounted on it—"

"Let's wait until the track is laid in Bopu."

"There is a hardened road as the foundation here, and if you want to pave it to Bopu, you have to use sleepers, and the track is officially laid."

"Why don't we just lay it! Anyway, the gauge is 1435mm, so there is no waste of repeated construction."

"Let's take this matter slowly, there is not so much steel to be laid. There are still one or two kilometers of track to be laid in the Bopu factory area-metallurgy and heavy chemical industry are indispensable for heavy load handling." Ma Qianju shook his head, He knew very well that as of yesterday, there were less than 20 tons of pig iron, wrought iron and steel in stock, and general industrial production could still handle it.It took another week for the pig iron from Guangdong to arrive.I don't have any iron ore in my hand, so I feel panicked.Always relying on sea imports—now he understands better than anyone else why the Japanese insisted on occupying the Northeast, even if they were beaten to pieces, they still wanted to hold on to "Manchuria".

Iron ore and blast furnaces are the foundation of industry.Ma Qianzhu thought about letting the long-distance exploration team carry out special exploration.

"We still have modification kits for this kind of self-propelled vehicle." Li Chiqi saw that the leaders were not interested in this kind of rickshaw, so he quickly ordered people to pack the things.Two foldable iron masts are installed on the flatbed truck. After entering the track, the masts are erected, and the sails are pulled up at the same time-the sails are hard and easy to retract.After the sail is raised, the wind propulsion is used to assist the riding, and the efficiency is naturally much greater than that of simply pedaling.

The advantage of using a hard sail is that it is more efficient in receiving wind, and it is very easy to lift, no rigging is required, and there is no requirement for manipulation. 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. In addition, we also want to try whether the efficiency of the soft sail is better."

"You don't need to try the soft sail to know it will work." Wen Desi knew the advantages and disadvantages of the hard sail and the soft sail. "You can't solve the rigging problem. Do these four people still need to operate the rigging?"

"I never thought about it."

"Lingao has abundant wind power resources, but it's not very reliable to drive flat cars. Is there a more reliable power system?"

"Yes, it's powered by a diesel engine. The experimental model uses Changchai's single-cylinder engine, which works well for towing flat cars." Li Chiqi pointed to the farthest one.A Changchai single-cylinder engine is placed horizontally at the rear of the flat car, with a simple gearbox, joystick, brakes, and a hanger. According to Li Chiqi, it is used to hang lanterns—the light bulb now belongs to the "one High-grade industrial materials", which are products that cannot be manufactured in a short period of time.

"If the steam engine can be miniaturized, it can also be equipped with a steam engine, as long as the strength of the frame is increased. The current materials are still a little worse."

"Then we have to hang tenders, we might as well build small trains." Wen Desi said with a smile - he is also a railway party member in his heart.

"What do the leaders think of these vehicles? Do you want to add some models?"

"The model number is enough for the time being, so grasp the details better." Wen Desi pointed out, "For example, your pedal-powered one doesn't even have an armrest around the four seats, and the diesel engine and gearbox are all naked. There is no protection at all, this is a matter of details, we need to consider more from the aspect of ergonomics—forget it, let’s find a professional to help us look at it.”

"That's a good thing." Li Chiqi said, "Mr. Wen, I heard that the executive committee is going to invite craftsmen from Europe?"

"I have this plan." Wen Desi was stunned for a moment, "What type of job do you have?"

"Yes, yes, I'd better find a wheelmaker for me, or find one from Guangdong." Li Chiqi had been worrying about this for a long time. Wooden wheelmaking is a very sophisticated craft. Obviously no one is good at Lingao.The wheels of the captured carts were so crudely made that they were not even round enough.Li Chiqi and others are now making 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 the wheels of rubber carts brought from another time and space.

"Okay, I remember this." Wen Desi said.

"That would be the best. If I have enough wheels, I can ride a sea of ​​horses and carriages." Li Chiqi said excitedly, and showed them the 1:2 models of several new carriages he had recently built.

The several models made by Li Chiqi are all very mature freight carriages from the 18th to 19th centuries in history.There is a very famous Scottish two-wheeled cart, which has a long and large carriage, but is so light that a horse can pull it.The two-wheeled truck can carry up to 1 ton during short-distance transportation.

There is also a four-wheeled cargo carriage, drawn by two horses, which can carry 3 to 4 tons of goods.The model Li Chiqi built was a Lincoln-style box-type four-wheeler.It had a deep rectangular hull with side panels that sloped upwards.The structure of this car is very simple and suitable for imitation.

"Several major roads are now undergoing surface hardening. Once completed, it will be too convenient to transport supplies with a four-wheeled carriage! A qualitative leap in the history of transportation!"

The four-wheeled carriage is one of the super artifacts of the traverser.But neither Wen Desi nor Ma Qianju had any interest in horse-drawn carriages—if you want to have a sea of ​​carriages in Hainan Island, you must first have a sea of ​​horses.Without horses, there is nothing to talk about.

In their opinion, instead of using any horse-drawn carts, it would be more practical to have more light and easy-to-use trolleys. On Hainan Island, people are much easier to find than horses, and food is also easier than horses.

"You should develop more carts." Mei Wan said the truth as soon as she opened her mouth, "There is no horse to pull the cart for you now! The workers on the construction site are all carrying the burden, and the efficiency is too low!"

"Yes, yes, I didn't expect that—"

"Okay, it's getting late, let's look at the water supply project." Ma Qianzhu unceremoniously interrupted Li Chiqi's presentation of the design model of the "Russian-style machine gun carriage" - although Du Wen wanted to listen up.

The next key supporting project is a large water supply system.The original underground water collection pipe system can only meet the daily water consumption of Bairen City residents-mainly drinking water.Facing the large-scale industrial water consumption in the future, it seems powerless.

The scale of water supply for large-scale industrial water is much larger than that of domestic water.The water from the Wenlan River is fine for watering vegetable gardens or flushing toilets, but not for industrial water.For this, a large waterworks had to be built.

Simple large-scale water treatment facilities are available in Bopu: Sedimentation tanks - sand filter tanks are 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 60-90cm sand layer in the pool, the bottom of the sand layer is gravel, and the bottom of the pool is a drainage system with gaps between bricks and stones to collect filtered water. Clear water.After filling the pool with the preliminarily settled river water, it flows through the sand layer between the sand and gravel at a very slow speed, and the solid matter in the water mainly stays on the surface of the sand.This kind of pool is simple and easy to operate, but the disadvantage is that the filtration speed is pitifully slow. In order to supply enough water, the area of ​​the pool must be increased.Every once in a while, the polluted surface sand has to be cleaned up, which is very labor-intensive.In the past, the demand for water supply in Bopu was relatively small, and this problem was not prominent.Large-scale use is unacceptable to the people who are not rich in land and labor.

The difference between this new system and the traditional filter tank is that the water is conveyed from the lower part of the sand layer, and an agitator is installed on the upper end of the sand layer. Work.The filtration speed 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 traversers.

"This water can only be used for industrial purposes?" Wu De asked.

"Besides being undrinkable, the general domestic water can be dealt with." Tian Jiujiu introduced that he, a person specializing in water supply and drainage, finally got into his job.

"Doesn't that mean we still need to build new waterworks?"

"No need." Tian Jiujiu said, "In fact, we only need to add some basic chemical treatment methods, such as adding alum—"

"Yes, I remembered that in the past, when there was no tap water, alum would be put in the tank after carrying the water, and it would be clean after stirring."

"After the chemical industry gets up, you can add bleach, or disinfect with chlorine gas."

"Damn it," Wu De scratched his scalp, "I used to dream of drinking pure natural water, and I felt uncomfortable when I smelled chlorine, but now I don't smell chlorine anymore, so I don't feel at ease."

"Where do you get chlorine gas?"

"Once the electrolytic salt tank in the chemical plant starts working, there is probably no place for chlorine gas to be used. Just pour it into the water—"

"You want everyone to drink dilute hydrochloric acid. You have to use hypochlorite!"

Everyone laughed.

There is one set of this system in Bairen Industrial Zone and Bopu Industrial Zone to meet their respective industrial water needs.Tian Jiujiu set up a steam pumping station at Bairen Power Station and Bopu respectively.In order to improve the efficiency and reduce the frequency of sand exchange in the filter tank, the river water will be put in the sedimentation tank for a day or two after being pumped up to allow various larger solid substances to settle, and those identifiable floating objects will be fished out manually.

The water treated by the fast sand filter is stored in the storage tank.The traveler uses a simple pressure device: a steam pump continuously pumps water into a high-level water tower, and uses 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 mechanical and metallurgical industries of the travelers who provided a better material foundation: it is precisely the ability to mass-produce boilers, steam engines, and cast various small and medium-caliber water-transporting cast iron pipes and valves that makes these Basic industrial facilities are possible.
