I'm still writing, everyone wait a while, and I'll change it after I'm done, at most half an hour. 『』????? One novel w?w?w?.? １xiaoshuo

In addition, I have been writing this chapter for a long time, and I am always trying to find a way to make it understandable to readers who are not in engineering units, but I have written and written, and there is too much knowledge about the transformation of the current station. After all, it is difficult to accept so much fresh knowledge at one time, and readers who are not engineering units will just read it, and readers of engineering units will also want to point out that writing novels is not like work, and sometimes it is difficult to cover everything.

In the end, I will write more details about the knowledge of station reform, because when I first came into contact with station reform, I didn't understand anything, and Baidu didn't know anything, I wrote these chapters, just to see if I could help everyone.

In the next period of time, Shucheng put all his energy on the transformation of the station.

As for the K88 bridge reinforcement, Shucheng also has time to go to a trip, and when the steel bars and formwork are inspected, Shucheng will take the supervisor to the construction site, and at other times, Shucheng is all put on the station reform.

The so-called inspection is to complete a process on site, and it must be qualified by supervision and inspection before entering the next process.

For example, after the reinforcement is tied, it is necessary to pass the guò inspection to see a series of problems such as the number of reinforcement roots, spacing, protective layer, etc., whether it is qualified, and if it is unqualified, it must be rectified, until it is qualified and the supervision agrees, and the formwork can be erected.

The station yard is actually our most common railway station, and the station renovation, as the name suggests, is the transformation of the railway station.

Why should the train station be renovated? The reason is relatively simple.

For example, when this railway was built, it was 30 years ago, and 30 years ago, the number of people near this station was less than 100,000, so the design of this station at that time may have been based on 200,000 people. A certain amount of space is reserved.

But thirty years later, the number of people in the vicinity of this station has reached millions, or even more. This station can no longer meet people's needs.

Therefore, this station must be renovated.

For example, 30 years ago, there were a lot of coal mines in this area. At that time, the station was built with these resources in mind, but 30 years later, there are not many coal resources in this place, but the number of people has increased a lot.

There is also this place, 30 years ago, there were no resources, but in the past 30 years, there are a lot of mineral resources, these resources need to be transported, and the railway is a good way.

This time. In order to adapt to the current environment, it is necessary to transform the station, that is, the station.

In any case, there are many reasons, but there is only one reason, that is, this station is not adapted to the surrounding environment now.

What is the general transformation of the station yard?

For example, the station yard renovation of the Jersey Line is 1o5o transformation, and 1o5o refers to the length of 1o5o meters, which is the distance between the two insulated joints on the main line in the station yard. This distance can be about 1o5o meters, but it cannot be less than 1o5o meters.

What is called a positive line, before understanding the word, one must understand a word. Stocks, what is the stocks.

When we get on the train at the train station, we often hear the conductor say something like this, how many platforms does the train stop, please passengers get on the train from the platform, these platforms. It's just a few strands.

For example, platform 1 is 1 strand, and platform 3 is 3 strands.

In the Jersey line, because it is a single line, there is only one main line, and it is generally a two-strand road.

For strands other than the positive line, we call them station lines.

How to distinguish between the main line and the station line, like the Jersey Line is a single line, when the train enters the station, the straight stock road that does not turn, does not pass through the turnout and enters the next strand road, and directly enters the railway station, is the main line.

And what is a turnout?

The turnout is a kind of line connection equipment that enables the rolling stock to transfer from one track to another, which is divided into before the fork, the center of the fork and the back of the fork.

The so-called front and back of the turnout is the front end of the turnout and the last end of the turnout, as for the center of the turnout, according to the different turnout numbers, the distance from the front and back of the turnout is not the same, and it is not the center of the turnout, which is the center of the turnout.

So, what is the role of the turnout?

Because a train can't just run on one track, it always has to turn, for example, if a train is coming in front of it, it has to turn to another track, relying on a switch.

You may not believe it, but the train driver is not at all in control of which lane the train enters, the train turns, and there is no steering wheel on the train at all!

The train goes to that side, which is completely controlled by the station dispatch room, and the guò switch guides the train into the designated track.

The Jersey Line has now been built for more than 40 years, and it cannot meet the requirement of 1o5o at all, so the only way to extend the turnouts to both sides of the battlefield is to make the length of the main line meet the requirements of 1o5o.

Since Haocun is relatively close to the station, he wants to use Haocun Station as a column, as long as this one battlefield is done well, the other battlefields will not be a big problem.

Prior to this, Shucheng carefully read the drawings of Haocun Station, and finally the station yard renovation of Jersey Station is very different from the station renovation of other lines.

The first point is that on the drawings of the station change, there is no coordinate of the turnout, only one mileage. Coordinates, like the latitude dimension of our geography, where a longitude is matched by a dimension, and the points on the earth are fixed.

Once there are coordinates, the construction technician can use the very level point to set the center of the turnout, so that the turnout is easy to find.

Now there are no coordinates, and Shucheng has no way to use the total station, which is an instrument for the engineering unit to measure and pay-off.

The second point is that Shucheng is now a more clumsy thing, because the Jersey line is too old, there is no way to find even the level point, that is to say, even if the turnout has coordinates, Shucheng cannot locate it.

The leveling point, also known as the control point of the engineering unit, usually, has two fixed leveling points. The given coordinates can be determined.

After Shu Cheng carefully studied the drawings, the three stations managed by Wei Jian, although the coordinates of the turnouts were not available, but when the stations were changed. Generally, one side is extended, and the other side remains unchanged.

Either the mileage of the new and old turnouts is given, and you can know that the distance between the centrifugal forks of the old turnouts is what is, and the mileage is reduced. It is the distance between the two turnouts, so that the position of the new turnout can be directly measured with a ruler.

What is a mileage? As a simple example, everyone should know very well that a highway, from a www.biquge.info to an end point, if we www.biquge.info the pen of this highway as o, we generally write the mileage of this place as koooooo, and the pen www.biquge.info start with the station. Extending a hundred meters forward, we wrote the mileage as kooo1oo, which is a hundred meters away from the www.biquge.info of Biqu Pavilion.

How about 3 roads and 29o meters? The mileage is koo329o, which means that the distance between this place and the www.biquge.info of Biqu Pavilion is 329o.

The mileage on the railway, which has the same meaning as this, is set to o from the beginning of the www.biquge.info of the Biqu Pavilion of a railway, so until the end of the railway, there is a mileage corresponding to each place.

So if the mileage of an old turnout is given on the drawing, the mileage of the new turnout is given. Because the old turnouts are actually stored on the spot, we completely follow the location of the old turnouts and measure the mileage difference between them, and get the results. This is where the new turnout is.

It's that simple.

This method is the throat on one side, and the mileage of the new and old turnouts is given, so it can be done.

Like Haocun Station, only the mileage of the new turnout is given, but the mileage of the old turnout is not given.

But at Haocun Station. The strands are only extended in the direction of the large mileage, and the small mileage side is just a changed turnout, but it does not extend forward.

A railway station with two directions, the place close to this railway Biquge.infoo www.biquge.infoo, we call it the small mileage side, and the far away from the railway Biquge.infoo www.biquge.infoo, we call it the big mileage side.

There are only two strands of road in Haocun, in addition to the main line, there is only one station line, which belongs to the simplest station transformation. On the small mileage side of Haocun Station, the original No. 1 turnout did not move, but the No. 5O-12 turnout was transformed into the No. 6O-12 turnout.

Turnout 5O-12, his meaning is, 5okg/rail, turnout No. 12.

In China, the types of rails are generally divided into four types, 43kg/5okg/6okg/75kg/What is the difference between these rails? At the very least, the height of the rail is different, 43kg/rail is the shortest, 75kg/rail is the highest, but the general railway, 75 rail is generally rarely used, and most of the current rails are 6o rails.

Of course, even the bottom width, head width, and waist thickness of the rails are different from one rail to another.

Haocun station is old, the main line not only has 6o rails, but also 5o, 43 rails, not to mention the station line, most of them are 43 rails.

According to the design requirements, the main line must be all guaranteed to be 6O rails, as for the station line, where the rails need to be changed, 5O rails must be used, but all 43 rails in the station yard are not required to be replaced with 5O rails.

Turnouts 5O-12 and Turnouts 6O-12, although they look like turnouts No. 12, but the length of this turnout is different, turnouts No. 6O-12 are obviously longer than turnouts No. 5O-12, and the distance from the front to the center of the turnout and from the center of the turnout to the back of the turnout is also completely different.

At Haocun Station, there are two sets of existing turnouts, both of which are turnouts No. 5O-12. For the other two stations, turnouts Zài 43-9 and 43-12 are still preserved.

After seeing that Haocun Station is only a large mileage side extension, and the 5O-12 turnout of the small mileage does not move in front of the turnout, Shucheng knows how this station has been transformed, and it will display the activities of the computer world, mobile phones, zombies, and the Christian shouting and killing advertisements of the computer world.
