In less than twenty minutes, a white Volkswagen off-road vehicle drove into the construction site, and Wei Jian stepped down from the co-pilot, holding a certain military cap in his hand. "Co*music*words*love*first*hair(http://www.klxsw.com

"Manager Wei, you're here." Zhang Xiaoyun and Shu Cheng stood up and greeted them.

"How many precipitation wells have been drilled?" Since Wei Jian has been busy with Hao Village's affairs, he rarely comes to Shangyunzhuang, and most of the things are decided by Zhang Xiaoyun and Shu Cheng.

Unless Wei Jian needs to report a plan, or needs materials for a meeting, he will call Shu Cheng and ask Shu Cheng to give him the latest completion of the construction site.

"Now it's the fourth, and the three drilled ones have begun to pump, so if nothing else, we can continue to dig tomorrow, and continue to drill the remaining few while excavating." Without waiting for Shu Cheng to speak, Zhang Xiaoyun explained to Wei Jian.

"Well, pay attention to safety when excavating, and stop digging once the water does not fall." Wei Jiandao.

Because of the high water level, three precipitation wells pumping for two days may not be able to lower the water level.

You know, the water level he fell was not just around the foundation pit, but in this area!

It is normal for the water to flow to a low place, and only by lowering the water level of this piece can the water level of the foundation pit be really lowered.

"Manager Wei, don't worry, I know it." Zhang Xiaoyun said.

For Zhang Xiaoyun's words, Wei Jian still trusts him, after all, his ability is there!

"Shucheng, you and I will go to the station to have a look, and see where the turnouts and rails are unloaded next, which will not affect the pre-paving in the future." Wei Jian said to Shucheng.

After speaking, Wei Jian strode forward, and Shu Cheng followed him. One look? Book w?w?w?・1?k?a?s?h?uc

For battlefield transformation, the turnouts and rails used, in general, will not be transported by car, for the simple reason that the standard rail gauge is 25 meters, and the standard rail of 12.5 meters and 6.25 meters is almost extinct.

Therefore, most of the rails used in the station are 25 meters, and those that do not need 25 meters can be cut off and reused.

It is not so easy to reload 25 meters of steel rails by car, not to mention 25 meters of steel rails in a mountainous place like the Jersey Line, even if it is 12.5 meters of rails, cars cannot transport them.

Even 25-meter rails could not be transported into the battlefield, let alone turnouts longer than steel rails, although the turnouts could be unloaded into several parts, and it was difficult to transport them by car.

On the railway, the rails and switches used by the station were transported by rail cars.

The rail car can be driven at both ends, reversing and moving forward without zài problems, and it is very convenient.

However, due to the limited space of the rail car, a single transport, like the 6O-12 switch, can transport up to two groups. The rails can be transported a little more, but because of the 2-hour point, the maximum of 5o 25-meter rails is the limit.

Because the rail car runs on the railway, it is necessary to report to the railway department in advance and wait for the arrangement of the railway department to stagger the running time of the rail car and the running time of ordinary trains.

The running time of each rail car is generally two hours.

Therefore, when transporting rails and turnouts, it is necessary to consider not only the transportation volume of the rail car, but also whether so many rails or turnouts can be unloaded in the key time.

Once the critical time is over, it's an accident!

Therefore, it is important to have an understanding of the site before transporting turnouts and rails, and once you have determined the place where the turnouts and rails are unloaded, it will be convenient to operate when waiting for the main points.

The place where the rails and switches are unloaded not only requires a certain site, but also needs to meet certain conditions.

For example, after the turnout is unloaded, where is it pre-laid?

The so-called pre-paving is to assemble the original scattered turnouts, and directly pull this group of turnouts into the big point, replace the existing turnouts or lines, and connect the new lines.

Even the storage of rails is also particular, such as how many rails are needed for that strand, and where is the general location, so as to minimize the reversal after unloading, because these reversals, the construction team has to calculate the cost.

Therefore, the rail car is also very particular about unloading the rails and turnouts, even if Wei Jian has worked on the line all his life, he does not dare to be sloppy.

Shu Cheng followed Wei Jian, first came to Pingchangli not far away, which belongs to the east end of Shangyunzhuang, a total of three sets of turnouts, four lines, about 12oo meters of lines.

The three sets of turnouts are two sets of turnouts 6O-12 and one set of 5O-9 turnouts.

All the main lines were replaced with P6O rails, and the station lines were replaced with P5O reusable rails.

"Do you have a track diagram?" Wei Jian frowned slightly, took Shu Cheng around, and asked

"Yes, Manager Wei." As he spoke, Shu Cheng handed Wei Jian the track map on the east side of Shangyunzhuang.

Wei Jian took the track diagram and looked at it carefully, giving Shu Cheng the feeling that he was pretending to be forced.

If in his previous life, Shu Cheng didn't know anything about station reform, and thought that Wei Jian was thinking about something.

But after several station changes, Shucheng can be said to know the station change well, unloading turnouts and rails, as long as you look at the track distribution diagram, you can come out soon, no need to think at all.

"Shu, how do you think the material should be unloaded here?" Suddenly, Wei Jian asked about Shu Cheng's intentions.

Shu Cheng thought about it, and didn't say anything polite to Wei Jian, and said his thoughts: "Manager Wei, because the time of the rail car is only ten days, the construction of the roadbed and the peaceful reconstruction will definitely not be completed, so the No. 1 turnout cannot be unloaded in position. ”

In the transformation of the station, the turnout pre-paving is divided into three categories, one is in place laying, which is assembled at the position where this group of turnouts should be laid, called in place laying.

There is also a kind of counterpoint laying, the so-called alignment, which is equivalent to laying into two parallel direct, and when the main point is reached, the turnout or rail that needs to be replaced is directly removed, and another group of turnouts is pulled in.

It is equivalent to moving the original straight line away, and then pulling the parallel straight line in and connecting it.

The third way of laying is mainly because the area is now, that is, it can not be laid in place, nor can it be laid in place, so find an open place, and after laying, this group of turnouts will be transported upside down.

This method is the most troublesome and the most cumbersome way of laying, and it will not be used until it is absolutely necessary.

"I mean, unload directly in front of the old No. 1 switchout, and at the same time, unload a strand of P5O rails in this place, and wait for the roadbed on this side to take shape, and transport it over!" Shu Cheng said his thoughts for the first time.

Hearing Shu Cheng's words, Wei Jian took a light breath, and there was no objection or affirmation.

In fact, at this moment, in Wei Jian's heart, he thought the same as Shu Cheng.

After all, in front of the No. 1 turnout, only a distance in front of the No. 1 turnout, the terrain is relatively open, just suitable for unloading the turnout and rails, for the reversal of the roadbed after the formation, there is no way to do it.

If it is unloaded in the place where the roadbed needs to be filled, then the roadbed should be reversed once, and the roadbed must be reversed once after filling, which is equivalent to two reversals, and the gains outweigh the losses!

The key point is that there is an old infrared machine room at the location of the newly laid No. 1 turnout, and it is impossible to unload a group of turnouts, otherwise Shucheng will mention yì to unload this group of No. 1 turnouts to that location, which can reduce reversal.

"Well, you go on." Wei Jian thought for a while.

"No. 3 and No. 5 turnouts, in my opinion, can be unloaded to the newly paved place, after unloading, do not assemble first, and then assemble after the roadbed is formed, I think there should be time." Shu Cheng continued: "As for the rails, my construction is unloaded next to the old No. 3 turnout, once the roadbed is formed, it is good luck, that place is open, and it happens to be unloaded there along with the P6O rail of the main line. ”

"Well, that's fine, if the roadbed is in time, it shouldn't be a problem." Wei Jian nodded.

Next, Wei Jian said his thoughts again, in fact, they were roughly the same as Shu Cheng's, and at the same time, he also asked Shu Cheng to write down the direction of the rail car on the day it was unloaded.

To put it bluntly, on the day of unloading the rails, it is necessary to explain to the railway station attendant where the rail car comes from, where to stop, which turnout to open, whether it is a straight strand or a curved bone, and where to stop and unload the track after opening.

After unloading in one place, how to control the turnout and enter the next place to unload the track, this series of things, and finally how to return, must be explained in detail.

Because these things are used for meetings on the day of the railcar point.

The reason why Wei Jian met with Shu Cheng was to settle this thing, and Shu Cheng needed to come up with a plan to unload the tracks.
