"It's useless, or transport people? The efficiency is also not very high. () This car can hold up to 10 people, right? Wen Deji was not satisfied.

"Can be used as an armed patrol car!" Wei Aiwen said, "Install armor on all sides, and then put machine guns on top of it—"

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

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

"Just shop! Anyway, it is 1435mm gauge, and there is no waste of duplicate construction. ”

"Let's take it slowly, we don't have so much steel to be laid. There are still one or two kilometers of track to be laid in the Bopu factory -- metallurgy and heavy chemical industry are indispensable for heavy loading. Ma Qianzhuo shook his head, he knew very well that there were less than 20 tons of pig iron, wrought iron and steel in stock as of yesterday, and general industrial production could still cope with it. It took another week for the pig iron from Guangdong to arrive. I don't have iron ore in my hand, so I'm panicking. Now he can understand better than anyone else why the Japanese were holding back their strength to occupy the Northeast, and even if they were all beaten to the ground, they still wanted to hold on to "Manchukuo."

Iron ore and blast furnaces, these two are industrial. The foundation. Let's let the remote exploration team carry out special exploration, Ma Qianzhuo thought.

"We also have retrofit sets for this self-propelled power. Item. Li Chiqi saw that the leaders were not interested in this kind of rickshaw, and hurriedly instructed people to load things up. Two foldable and inverted iron masts were installed on the flatbed, which were erected when they entered the track and the sails were pulled up at the same time - the sails were rigid and easy to retract. After raising the sail and using the wind to propulse, the efficiency of riding is naturally much greater than that of simply pedaling.

The benefit of using a hard sail is the efficiency of being affected by the wind. It is high, and it is very easy to lift, no rigging is required, and there is no requirement for manipulation, which is very practical for flat cars.

"This is still a preliminary design, and we invited a specialist who studied fluid mechanics. Traders are testing to get the best sail shape and also want to see if the soft sail is more efficient. ”

"The soft sail doesn't need to be tried, you know it can't work." Grace of the hard sail and the soft sail. The shortcomings are clear, "You can't solve the rigging problem alone, do these four people still have to operate the rigging?" ”

"I didn't think about it."

"Lingao's wind resources are quite abundant, which are used to drive flat. The car is still not very good. Is there a powertrain which is possible to kao? ”

"Yes, it's a diesel engine. Power, the Shiyan type uses a single-cylinder engine of Changchai, which has a good effect on towing flat cars. Li Chiqi pointed to the farthest one. A Changchai single-cylinder engine sits horizontally at the rear of a flat car, with a simple gearbox and joystick, brakes, and a pylon, which, according to Li Chiqi, is used to hang lanterns -- light bulbs are now "first-class industrial materials" and are products that cannot be manufactured in a short period of time.

"If the steam engine can be miniaturized, it can also be installed, as long as the frame is stronger. The current material is still a little worse. ”

"Then you don't have to hang a coal water truck, you can just build a small train." Wen Deji said with a smile - at heart he was also a railroad partyman.

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

"The model is enough for the time being, and the details are better grasped." Wen Desi pointed, "For example, you are pedal-powered, there is not even a handrail around the four seats, and the diesel engine and gearbox are naked, and there is no protection at all, this is the details of the problem, and it is necessary to consider more from the ergonomic aspect - forget it, it is better to find a professional to help you take a look." ”

"That's a good idea." Li Chiqi said, "Mr. Wen, I heard that the Executive Committee is going to invite craftsmen from Europe? ”

"That's the plan." Wende paused, "What kind of work do you have?" ”

"Yes, yes, it's better to find me a wheelsmith, or find me one from Guangdong." Li Chiqi has been worried about this for a long time, wood wheel making is a very profound craft, and no one in Lingao is good at it. The wheels of the seized trolley were so crudely made that they were not even quite round. Li Chiqi and others are now making their own wheels, although the quality is good, but probably because the process is illegal, it takes several days to build a wheel, and the products are quite poor. Many of the vehicles they produce now use the wheels of rubber trolleys brought from another plane.

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

"That's the best, if I have enough wheels, I'll be able to storm the carriage." Li Chiqi said excitedly, and showed them the 1:2 models of several new carriages he had recently built.

Several models made by Li Chiqi are all very mature freight carriages in the 18th ~ 19th centuries in history. There are the very famous Scottish two-wheelers, which have a long, large box, but are so light that they can be pulled by a single horse. Two-wheeled trucks can carry up to 1 ton of vehicles for short distances.

There is also a four-wheeled freight carriage, which is pulled by two horses and can carry 3~4 tons of goods. The model built by Li Chiqi is a Lincoln-style box four-wheeler. It has a deep rectangular body with sideplates slanted out on all sides. The structure of such a car is very simple and suitable for imitation.

"Several major roads are now being hardened, and once that's done, it's so convenient to transport supplies in a four-wheeled wagon! A qualitative leap in the history of transportation! ”

The four-wheeled carriage is one of the super artifacts of the traverser. However, neither the heirs nor Ma Qianzhu and others had much interest in the four-wheeled carriage -- if they wanted to storm the carriage sea on Hainan Island, they had to storm the horse sea first. Without horses, nothing can be talked about.

In their opinion, it is more practical to build more light and easy-to-use trolleys than to build horse-drawn carriages, which are much easier to find and eat than horses.

"You'd better develop more trolleys." It was Mei Wan who said her true feelings as soon as she opened her mouth, "How can there be a horse to pull the cart for you now!" The workers on the construction site are carrying the burden, and the efficiency is too low! ”

"yes, yes, I didn't expect—"

"Okay, it's not too early, let's look at the water supply project." Ma Qianzhuo unceremoniously interrupted Li Chiqi's presentation of the design model of the next "Russian-style machine gun carriage" - although Du Wen was eager to hear it.

The next major supporting project is a large-scale water supply system. The original underground water collection system can now only meet the daily needs of the residents of Bairencheng - mainly drinking water. In the face of large-scale industrial water use in the future, it is too much to do.

The scale of water supply for large-scale industrial water is much larger than that for domestic use. The water from the Wenlan River is okay to water vegetable gardens or flush toilets, but it is not qualified to be used as industrial water. To do this, a large water plant had to be built.

Simple large-scale water treatment facilities, through the public in Bopu have: the use of sedimentation tank-sand filter tank to purify water quality, for factory and general life use. This method is simple. Build one or more waterproof masonry pools, place 60~90cm sand layer in the pool, the bottom part 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. After filling the pond with the initial sedimentation of river water, it flows slowly through the sand layer from the gravel, and the solid matter in the water is mainly trapped on the surface of the sand. This type of pond is simple and easy to implement, but the disadvantage is that the filtration speed is pitifully slow, and in order to be able to supply enough water, the area of the pond has to be increased. Every once in a while, the contaminated surface sand has to be cleaned up, 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 is unacceptable to the traversers who are not rich in land and labor.

This new system differs from the traditional filter tank in that the water is transported from the lower part of the sand layer, and an agitator is installed at the upper end of the sand layer, which continuously agitates the sand to assist in the flushing of the flowing water in Xiangshang. The filtration speed is much faster – of course, not as effective as a slower sand filter. Fortunately, mechanical filtration systems treat water for purity, not for drinkability. It's great for traversers.

"This water can only be used industrially?" Wude asked.

"In addition to not being able to drink, general domestic water can be dealt with." Tian Jiujiu said that he, a professional in water supply and drainage, finally got into the industry.

"Doesn't that mean we have to build a new waterworks?"

"No." Tian Jiujiu said, "Actually, as long as you add some basic chemical treatments, such as adding alum—"

"Yes, I remember, in the past, when there was no running water, you had to put alum in the tank when you came back with water, and it would be very clean when you stirred it."

"After the chemical industry comes up, you can add bleaching powder or disinfect it with chlorine."

"Damn," Wu De scratched his scalp, "I used to dream of drinking pure natural water, and I was not happy to smell chlorine, but now I can't smell chlorine anymore." ”

"Where can I find chlorine?"

"As soon as the electrolytic salt tank of the chemical plant started, I was afraid that there would be no place to use chlorine. Straight into the water—"

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

Everyone laughed.

This system is available in Bairen Industrial Park and Bopu Industrial Park to meet their respective industrial water needs. Tian Jiujiu set up a steam pumping station at Bairen Power Station and Bopu Power Station. In order to improve efficiency and reduce the frequency of sediment change in the filter tank, the river water is pumped up and left in the sedimentation tank for a day or two to allow the larger solid materials to settle, and the recognizable floating objects are fished out by man.

The water treated by the rapid sand filter is stored in the tank. The traverser uses a simple pressure device: a steam pump continuously pumps water into a high-level water tower, which uses the gravity of the tower to supply water to the factory.

The construction of the new water supply system was made possible thanks to the mechanical and metallurgical industries of the Traverser for providing a more material base: it was the mass production of boilers, steam engines, cast iron pipes and valves of various small and medium-sized calibers that made these basic industrial facilities possible.
