Just now, she was "giggling" and laughing, but in an instant, Chu Xiaoya suppressed her laughter, and her tone became serious: "Mayor, what do you think of the city's traffic work through this walk?"

Chu Tianqi said: "On the 7th, the city determined my division of labor, in charge of public security, justice, fire protection, transportation, communications, letters and visits, etc. I am no stranger to public security and judicial work, and I have also been in contact with fire protection and letters and visits, especially fire protection and communications, which are not directly managed by the city. However, the transportation work is related to public infrastructure, and the responsibility is heavy, and I have no previous experience in charge of it, and the position of director has been vacant, so I am mainly familiar with the transportation work.

In fact, I haven't had much contact with railways and air transportation, and I have only learned about roads for a while. Through the field inspection of this section, combined with the relevant original data, I think the highways in the city have the following characteristics: 1. The overall grade of the highway is not high, especially the high-grade highway is few, which is incompatible with economic development and hinders economic development. Second, the current situation of the highway is not optimistic, and the damage is serious, which shortens the service life of the highway. Third, the quality of individual highways is not high. Of course, this is just my guess, a conclusion that has been reached through frequent renovations. Fourth, high-grade highway ......"

"I agree with most of your analysis. After listening to the other party's words and expressing her views, Chu Xiaoya asked: "What do you think is the reason for this situation?

"I didn't fully understand the cause, and most of it was just speculation, so I still didn't talk about it. How to solve the problem? Strive for the construction of new high-grade highways. New or repaired roads are guaranteed in quality and quantity. I've just thought about it, I haven't thought about the details yet, and I plan to listen to the advice of professionals in the near future. Speaking of this, Chu Tianqi smiled, "You have been in charge of traffic work, and you have served in the Department of Transportation, and now you are the director of the Municipal Transportation Bureau, you must be professional enough, you will talk about it first." ”

"Strictly speaking, I'm not a professional, but I was introduced to this work before you. In the past six months in the Department of Transportation, I have learned some information about the province and even the whole country. Now let's look at it first, and I'll report after reading it, so that we can also connect theory with practice. Is it okay?" Chu Xiaoya asked for advice.

Chu Tianqi nodded and agreed: "Okay, then let's take a look first." ”

"Looking at the front and rear roads, there are a lot of cracks, and if you look at this section, there are still cracks. The highway structure has three layers, the surface layer, the base layer, and the cushion layer, the cement concrete of the base layer is rigid, and the surface layer of asphalt is flexible. The thermal expansion and contraction coefficient of the base layer and the surface layer are not the same, and the roads below the second grade are often cracked after the spring thaw due to the lack of thickness of the asphalt surface layer. Even if this crack is not treated, it will naturally close after a few months as the temperature changes. However, if not treated in time, rainwater will drill under the oil surface, which will affect the service life of the surface layer. What's more, if there is a problem with the quality of the base, the infiltration of these rainwaters will become the culprit of road slurry. Therefore, in April and May every year, the highway should be filled with joints.

Now in some places, asphalt grouting is no longer used, but special asphalt pavement sealants are used. However, this technology has not yet been fully promoted, mainly because its side effects are still being demonstrated, and it is not entirely clear how much it is related to local temperature and humidity.

This grout is also particular, if the procedure is omitted, it will not achieve the desired effect. Look at this crack, it should be the old crack from last year. Look at the bottom of this piece of grouted asphalt, there are so many impurities on it, which is caused by the lack of dust blowing at that time. Look at this big crack again, you can see how badly the edge is damaged, this is when the seam was filled last year, the edge was already slightly damaged, and the seam should be cut and expanded, but it was not done at that time.

Looking at this crack again, needless to say, it must be that the surface layer is damaged by water ingress. As for whether the surface layer is congenitally stunted, or caused by improper or untimely joint filling in the later stage, it can only be known by breaking the surface layer or drilling and sampling. Whatever the reason, as long as there is such a serious crack in the surface layer, the base layer must already have a lesion. If it is not dealt with in time, if there is water seeping in, it is specified to turn the slurry, and the piece in front of you will not run. And ......" Chu Xiaoya hunched her waist as she walked, pointing to the ground. Sometimes he squats down, picks up a piece of it, or puts his hand into a crack to give a speech.

Although he didn't know much about the phenomenon and causes of road damage before, after listening to Chu Xiaoya's on-site explanation, Chu Tianqi was completely clear.

Walking all the way, talking and listening all the way, the two people surnamed Chu arrived at a concrete bridge deck.

Chu Xiaoya pointed to the junction between the bridge deck and the road surface: "There is a problem here, as for whether it is the deformation of artificial filling during construction, or the consolidation and settlement of natural soil foundation, it needs to be further studied." Of course, it may also be that the design is not good, or it may be that there is a problem with the expansion joint device itself, or it may be that the post-pouring pressure filling material is not selected well, anyway, there are many possibilities. But now there has been a large difference settlement here, causing the bridge head to jump. The bridge head jumping car not only directly affects the driving comfort, the key also increases the driving risk, and the vehicle in the bridge frequent braking, braking, collision, and will aggravate the damage to the road surface on both sides of the expansion joint, which is a vicious circle. Solving the problem of jumping at the bridgehead has become a problem that must be paid attention to in highway design, and it is also a problem that has been paid attention to in highway design. I went down to take a look just now, and there is a crack in the bridge deck, do you want to take a look?"

"Let's go. Chu Tianqi immediately responded.

Along the gentle slope of the shoulder, Chu Tianqi and Chu Xiaoya got off the road and walked under the bridge. No wonder Chu Xiaoya had mud on her feet, it turned out that the mud that had accumulated under the bridge in the light rain the night before had not dried up.

Looking up and pointing to the top of the bridge, Chu Xiaoya said: "You see, this is a shrinkage crack, which is caused by the shrinkage of concrete, and it is the most common. This is a load crack, which may be related to design, construction, and use, and the specific situation must be specifically checked and analyzed. If you look at this again, the steel bars are exposed, this is the exposed tendons, which will definitely rust after a long time, and must be dealt with as soon as possible. Look at these cracks again, these cracks are so cracked, although they are a little deeper, but they are not a big problem. Although this crack is shallow, it is in this direction, so you have to pay attention to it, from the current point of view, it may be caused by the prefabricated panel, but it also needs to be observed regularly. Look at the wall again......"

After looking at the bridge, Chu Xiaohe pointed to the slope protection and green belt, and talked about repairing the shoulder, slope, mowing grass, cleaning up the debris in the collection well and drainage tank.

Just like a guide, he led Chu Tianqi down the road for a long distance before Chu Xiaoya proposed to go up.

Chu Tianqi didn't worry about going up and down, trotting down when he was going downhill, and there was no problem when he went up. But when Chu Xiaoya was on it, it was a little more difficult.

Seeing that the other party was using both hands and feet, but it was still difficult to move forward, Chu Tianqi had no choice but to stretch out his hand.

"Hmph, no gentlemanly demeanor at all. Chu Xiaoya continued to use her hands and feet, and did not take the hand.

Just now, he was only thinking about whether men and women could be imposed, but now seeing that the other party was picking out the reason, Chu Tianqi also felt that he was at a loss, so he had to move two small steps and stretched out his hand again: "Come on." ”

Chu Xiaoya hesitated for a moment before stretching out her hand.

Although he was holding a gloved hand, Chu Tianqi still felt a little awkward.

And Chu Xiaoya did not take advantage of the situation, but used her hand hard.

was distracted, and was suddenly pulled by the other party, Chu Tianqi suddenly felt unstable on his feet, and his whole body rushed forward.

I wanted to play a prank, but seeing that the other party's body was out of control, Chu Xiaoya couldn't help but panic, and screamed "ah".

That is, Chu Tianqi, on the slope of such a slope, his body rushed forward, and he was about to pounce on Chu Xiaoya, but he forcibly restrained his body leaning forward. The angle at which he was standing was very strange, and what was even more strange was that he was only half a finger away from Chu Xiaoya's face. It's good to keep your body in, otherwise both of them will inevitably fall underneath. Although it is not high from below, although it is all land, it may not be in great danger, but it will also make a gray face, and the appearance of the two of them landing on the ground will be indecent.

When she was checking the bridge just now, Chu Xiaoya had already taken off her mask, and now she felt the breath of the man above, she couldn't help but panic, her cheeks quickly reddened, and her breathing was a little short.

It was Chu Tianqi who quickly adjusted his posture, led Chu Xiaoya, and went up to the road step by step.

"It's so tight to catch people. Chu Xiaoya blushed and shook her arms.

Chu Tianqi let out an "oh" and hurriedly let go, his face turned red all of a sudden.

Chu Xiaoya laughed again: "Giggles...... You're so funny, you think you're a little boy, and your face is red. ”

"You don't either. After a shot back, Chu Tianqi hurriedly diverted the topic, "I suddenly found that you are so profound, not like a department-level leader." ”

"What about you, aren't you here too?" After asking rhetorically, Chu Xiaoya said, "The traffic work is very important, and I just went to the bureau again, and people will inevitably disapprove of the female director." I only have to go to the front line to get first-hand information, prove my professionalism to those who claim to be professionals, and put the theory I have accumulated before into practice. Of course, as for the people in the bureau, I'm not in a hurry, and they don't have anything difficult to deal with. ”

"With your IQ and EQ, it's absolutely fine to condition them. Half-seriously teasing, Chu Tianqi mentioned the previous question again, "What do you think is the main problem of the city's highway traffic work?"

"What I said may not be accurate, and it is still up for debate. After making an explanation, Chu Xiaoya continued, "I think the biggest problem in the city's highway work has three points: first, the concept is outdated, and the new highway grade has not kept pace with the times; second, the mission of the highway people is not strong; third, the continuity of traffic engineering is not strong, due to the change of leadership, there is a phenomenon of changing the order overnight. ”

"Then how to solve it?" Chu Tianqi asked.

"It is necessary to have a strong sense of responsibility for the leader to make forward-looking planning and get the approval of the higher authorities. Specifically......" Chu Xiaoya said eloquently.

When he was in Xuyuan County, although Chu Tianqi had a lot of contact with Chu Xiaoya, the impression that the other party gave him was a woman with an elegant temperament but not pretentious. Today he saw her reckless side again.

And now, just now I felt the seriousness of Chu Xiaoya's work, and listened to the other party's incisive speech, he has a new understanding of her: a strict female director.
