In the afternoon of the next day, Shu Chengcai and Ren Changhong began to rush to the direction of the project department.

However, Shu Cheng did not return to the project department, but returned directly to the Haocun station.

I played a little crazy last night, this meal and three hours of KTV in one night cost Shucheng more than 6,300, which made Shucheng's heart ache for a while.

But fortunately, on the way back to the project department, Ren Changhong had already spoken, asking Shu Cheng to complete some invoices, and then directly to Ren Changhong, and Ren Changhong would come forward to help reimburse.

In the engineering unit, many leaders of the project department go out to play, spend all the money of the public, and come back to find various catering invoices for reimbursement.

Many leaders' favorite thing to do is to invite leaders to dinner and deal with things.

After a meal, even if they only eat a hundred, they can make five or six hundred, and in the end they can make a net profit of hundred, which is not a new thing in the engineering unit.

And to deal with things, the commission from it, is higher.

For this cost, Ren Changhong also knows that there is a lot of consumption, and it is completely borne by Shucheng, and the pressure is relatively high. And reimburse part of it yourself, there is no problem at all. Although Ren Changhong was demoted, it did not affect his reimbursement.

After returning to Haocun Station and resting for one night, Shucheng was busy again.

Now the K88 bridge reinforcement project and the K9 bridge reinforcement project are in full swing. Half of the bridge reinforcement of K88 has also been installed, and the output value of Hao Cungong this month is once again among the best.

In order to speed up the progress, Zhao Qingming transferred two groups of people, one to speed up the completion of the K88 bridge reinforcement project, and the other group, all of which attacked the K9 bridge reinforcement.

Today, the first cap of the bridge reinforcement of K9, the foundation pit has been excavated, the cushion has been completed, and now the drilling construction is underway, and the first cap can be poured in a maximum of four days.

Mainly because on the original caisson, it is necessary to plant reinforcement, which is more troublesome, and the purpose of planting reinforcement is, of course, to make the old caisson and the new bearing platform effectively combined.

For these, Shu Cheng didn't care too much, and threw it directly to Zhang Min, for the matter of the protective fence, Shu Cheng did not arrange a technician to monitor and control it at all, it was more an ancillary facility, and there was a team leader, it should not be a problem.

Shu Cheng took Wu Peng and went to Haocun Station.

The purpose of going to Haocun Station today is very simple, Shucheng just wants to set the two sets of turnouts at Haocun Station.

For the position of the No. 1 turnout, because the No. 1 turnout remained unchanged before, Shucheng directly measured the fork with an insulating ruler, and finally measured the fork according to the fork center.

On railways, two railroads cannot be measured with conductive steel rulers, for the simple reason that once two railroads are connected, the signal lights will change.

As soon as the red signal light turns green, it will mislead the train, and the most severe result is a crash.

Here, the issue of traffic lights comes in.

In a railway station, in general, there are only two kinds of signal lights, one inbound and one outbound.

For example, Haocun Station is a single line, and the entrance signal lights are all at the throat on both sides of the railway station, which is about 1. kilometers away from the entrance signal lights.

The incoming signal lights are all high columns, what is a high column?

The high pillar refers to a high pillar set by this signal light, which corresponds to the low column.

The incoming signal lights and the outbound signal lights of the main line are built with high columns, while the outbound signal lights of the station line are built with low columns.

In general, for single-track railways, there is only one inbound signal, and there are several outbound signals, depending on how many strands of track there are. For example, at Haocun Station, there are only two tracks, and there are only two outbound signals on one side. If it is a three-strand road, then there are three outbound signals.

Insulated joints are installed near the rails adjacent to the incoming and outgoing signal lights.

The insulated joints of the incoming signal light rails are generally one meter to the left and right, that is, the position of the insulating joints and the incoming signal lights cannot be staggered by more than one meter on the left and right.

For the location of the outbound signal and the insulating joint, the distance between the two should not exceed 6.5 meters on the center side of the station, and for the position of the throat side on both sides, the distance between the two should not exceed 1 meter.

That is, when your insulation joint is set, the position of the signal light is almost determined.

And what is the function of insulating joints?

The so-called insulation is to isolate the conduction of electric current.

In this case, between the inbound signal light and the outbound signal, this section of the rail should be independent, that is, it is not connected with the rail in the middle of the station, nor is it connected with the rail outside the inbound signal.

For example, between the two adjacent station yard approach signals, the rails are connected, within this range, there is no insulating joint, the train from this area, into the incoming signal of a railway station, across the insulating joint of the incoming station, because the train axle is equivalent to a conductor, after entering the incoming insulating joint, because the two axles let the middle part of the rail between the incoming insulating joint and the outbound insulating joint communicate, the signal light will change.

When the train enters the station, the front and rear parts of the locomotive must be in the two outbound signals on both sides, that is, in the insulated joints of the two outbound signals, so that the train will not affect the signals other than the outbound signals.

The establishment of insulating joints is also directly related to the rail distribution, but now in order to cooperate with the construction of the engineering unit in front of the station, the general signal lights are set up in accordance with the rail distribution of the pre-war construction unit.

One of the prerequisites for this setting is that a length of 1,050 meters must be met, which is the minimum prerequisite.

The use of the total station line, only two in the morning, to Shucheng to come, there is no test at all, less than 30 minutes, it is put away, the main time is spent on walking.

Three days later, Shu Cheng positioned the turnouts of Hao Cungong's three stations, but it was only a preliminary position, and he did not lead out the pile position.

A week later, Zhang Tianhu and Ren Changhong, the managers of the project department, came to the site to investigate, and Wei Jian and Shu Cheng followed, because Shucheng put the forks in advance, and even the track distribution drawings of the three stations were drawn.

Zhang Tianhu's affirmation of Shu Cheng made Shu Cheng weak.

In fact, Shu Cheng has always insisted that many things, it is essential to prepare early, if the leader wants to chase after him with a stick, he will not only be scolded but also thankless.

ps: Today's overtime, just one chapter, fine inspection, comrades in the engineering unit, you know!
