"It's useless. How about transporting people? It's not very efficient. 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, "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 laid. There are still one or two kilometers of track to be laid in the Bobu factory area - metallurgy and heavy chemical industries are indispensable for the transportation of heavy objects." Ma Qianxu 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 would not arrive for another week.
There is no iron ore, and I feel panicked. I have always relied on sea imports - now he can understand better than anyone why the Japanese held back their energy and insisted on occupying the Northeast, even if they were beaten to a pulp, they still wanted to capture "Manchukuo"
Don't let go.
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 modification kit for this kind of self-propelled rickshaw." Seeing that the leaders were not very interested in this kind of rickshaw, Li Chiqi quickly ordered people to pack up the things. Two foldable iron masts were installed on the flatbed truck, and he entered
After the track, erect the mast and pull up the sail at the same time - the sail is hard and easy to retract and unfold. 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 is more efficient in catching wind, and it is very easy to lift and lower. It does not require rigging and there are 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 knew 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 unreliable. Is there a reliable power system?"
"Yes, it is powered by a diesel engine. The experimental model uses a Changchai single-cylinder engine, which works well for towing a flat car." Li Chiqi pointed to the farthest one. A Changchai single-cylinder engine crossed the
Placed at the rear of the flat car, there is a simple gearbox, joystick, brake, and a hanger. According to Li Chiqi, it is used to hang lanterns - light bulbs are now classified as "first-class industrial materials" and are short-term.
Products that cannot be manufactured within.
"If the steam engine can be miniaturized, it can also be equipped with a steam engine. All it takes is to 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 - at heart he was also a railway party member.
"What do the leaders think of these vehicles? Should we add more models?"
"The model number is enough for the time being. We need to grasp the details better." Wen Desi pointed out, "For example, your pedal-powered one has no armrests around the four seats. It also has a diesel engine and a naked gearbox.
There is no protection at all, this is a matter of details, and we need to consider more from the ergonomic aspects - 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?"
"We 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 are very rough, and even the roundness is not quite right. Li Chiqi and others now make their own wheels. Although the quality is good, the workmanship is probably illegal.
Because of this, it takes several days to make a wheel, and the product is quite poor. Many of the vehicles they produce now use rubber trolley 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 the very famous Scottish two-wheeled carriage. This kind of carriage has a long and large carriage, but it is very light and lightweight.
Horses can pull it. Two-wheeled trucks can carry up to 1 ton during short-distance transportation.
There is also a four-wheeled cargo carriage, which is pulled by two horses and can carry 3 to 4 tons of cargo. The model Li Chiqi built is a Lincoln-style box-type four-wheeler. It has a deep rectangular body with the surrounding side panels upward.
It stretches out at an angle. The structure of this kind of 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 supplies with four-wheeled carriages! A qualitative leap in the history of transportation!"
The four-wheeled carriage is one of the super artifacts for time travellers. However, neither Wen Desi nor Ma Qianzhu and others have any interest in the four-wheeled carriage - if you want to conquer the sea of carriages on Hainan Island, you must first conquer the sea of horses. Without horses, what?
Can't even talk about it.
In their opinion, it is more practical to build more light and easy-to-use trolleys than to build carriages - people are much easier to find than horses on Hainan Island, and food is easier to eat than horses.
"You should develop more handcarts." Mei Wan said the truth as soon as she opened her mouth, "There are no horses to pull the carts for you now! The workers on the construction site are all shouldering the burden, and 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 originally adopted underground water collection pipe system can now only meet the daily water needs of Bairencheng residents - mainly drinking water. It will not be able to cope with the large-scale industrial water use in the future.
The scale of large-scale industrial water supply is much larger than that of domestic water. The water from the Wenlan River can be used directly to water vegetable gardens or flush toilets, but it is not qualified to be used as industrial water. For this reason, a large-scale water plant must be built.
Simple large-scale water treatment facilities are available in Chuanzhongbopu: using sedimentation tank-sand filter tank to purify water quality, which can be used in factories and general life. This method is very simple. Build one or more waterproof
For a masonry pool, a 60-90cm sand layer is placed in the pool. The bottom part of the sand layer is gravel. The bottom of the pool is a drainage system made of bricks with gaps between the stones to collect filtered clean water. The initially settled water is
After the river 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 pond is simple and easy to operate, but the disadvantage is that the filtration speed is pitifully slow. In order to be able to supply
To obtain 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 small, and this problem was not prominent. Large-scale use of the land
It is unacceptable for people who are not rich in labor and labor.
The difference between this brand-new system and the traditional filter tank is that the water is transported from the lower part of the sand layer, and a stirrer is installed on the upper end of the sand layer. This stirrer continuously stirs the sand and assists in the flushing of the upward flowing water.
work. The filtration speed is greatly accelerated - of course, the filtration effect cannot be compared with the slow sand filter. Fortunately, the mechanical filtration system treats water for purity rather than drinkability. For travelers
It is said to be very applicable.
"This kind of water can only be used for industrial use?" Wu De asked.
"Except for not being drinkable, general domestic water can be treated," Tian Jiujiu said. 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, "Actually, you just need to add some basic chemical treatments, 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 develops, you can also add bleaching powder or use chlorine 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 set of this system in Bairen Industrial Zone and Bopu Industrial Zone to meet their respective industrial water needs. Tianjiujiu has set up a steam pumping station in Bairen Power Station and Bopu respectively. In order to improve efficiency and reduce sand exchange in the filter pool
Frequency, after the river water is pumped up, it will first stand in the sedimentation tank for a day or two to allow various larger solid substances to settle, and those identifiable floating objects will be fished out manually.
The water treated by the rapid sand filter is stored in the storage tank. The traverser uses a simple pressure equipment: a steam pump to continuously pump water into a high water tower, and uses the gravity of the water tower to pump water into the factory.
Water supply.
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.
