Chapter 37 Construction Results

"Comrade from afar, why did you come to such a conclusion?" At this critical juncture, Hong Xianguo was very cautious.

"There are two reasons for this." Lin Yuanfang said: "First, the interior of the four-kilometer-long tunnel is all cement mortar strip stone masonry, with good waterproof and seepage ability, even if it is because of the long building age, the waterproof and seepage surname can be reduced, but the time used for drainage will not exceed four hours, even if there is some local leakage, but the problem will not be too serious." Second, from the geological survey data, the tunnel was built in the red clay layer. The water stability of the red clay layer is better, the strength is relatively high, and it will not collapse even if it encounters a large water flow and seeps. There will be no impact on the ground buildings. ”

Hong Xianguo pondered for a moment and asked Yao Ziping: "Yao Gong, what do you think of the views of comrades from afar?" ”

"If the tunnel is indeed as he said, the interior is all cement mortar strip stone masonry, and it is built in a layer of red clay, then it can still withstand four hours of water erosion and soaking." When Yao Ziping said this, he bit the word "indeed" very hard.

"It's not hard to prove if that's the case." Lin Yuanfang said: "Open the tunnel and send someone down to check the internal structure of the tunnel." You can also select a few points and take soil samples to see if there is a red clay layer underneath. ”

"Director Long, Director Wang, what are your opinions?" Hong Xianguo asked.

Wang Tianfang, who is also a technical cadre, said: "I think the method of comrades from afar is feasible. It didn't take long to investigate the site and take soil samples. ”

"I agree." Long Tianfei followed behind Wang Tianfang to express his position.

"Okay, then let's split it up." Hong Xianguo said: "Director Long, you immediately arrange for someone to investigate and take samples under the tunnel. ”

"Yes, I'll arrange it right away!" Long Tianfei agreed.

Hong Xianguo said to Lin Yuanfang again: "Comrade Yuanfang, I have to ask you to work hard here, you have to be with Yao Gong to study the specific plan for using tunnel drainage." As soon as the results of the on-site investigation came out, we immediately implemented the drainage. ”

Speaking of this, Hong Xianguo paused, reached out and patted Lin Yuanfang's shoulder gently, and asked in a soft voice, "Can your body withstand it?" "There was a lot of concern in my eyes.

Lin Yuanfang's heart was hot again, and he said: "Secretary Hong, I don't have any problems with my body, I have basically recovered, and I will wait for the stitches to be removed tomorrow." Besides, I can still undertake the task of just studying a drainage plan and moving my mouth, and not letting me go to the front line of drainage to drain water. ”

"Okay," Hong Xianguo stood up and waved his hand, "Time is urgent, everyone should act separately." ”

*********************************************************************

Three hours later, the hour hand pointed to 12:30 p.m. on September 20. In the meeting room of the Construction Committee, another meeting was held urgently. This time, in addition to Hong Xian, secretary of the county party committee, Liu Hongwei, the county magistrate, as well as the deputy secretary and deputy county magistrate in charge of urban construction, were urgently transferred back from the front line of drainage to attend the meeting.

At this time, the focus of the meeting was Lin Yuanfang, who was wearing a hospital gown. At this time, he was holding an oil paint pen and standing in front of a huge map of the urban area of Binan County.

"Judging from the soil samples from the five sampling sites, the outside of the tunnel is indeed a relatively well-stabilized red clay layer. And the internal structure of the tunnel is indeed made of cement mortar strips of stone masonry," Lin Yuanfang said, "so it is technically no problem for the tunnel to act as a temporary drainage channel." ”

"According to my calculations and Yao Gong's calculations, in order to quickly drain the stagnant water in the urban area, we need to select five excavation points to bring the stagnant water in the urban area into the tunnel. And these five excavation sites, we plan to choose these places. Lin Yuanfang said as he circled the location he thought was appropriate on the map of the city with a watercolor pen, and then asked, "Do you have any different opinions?" ”

Liu Gong of the Urban Construction Section of the Construction Committee looked down at the drawings in front of him, raised his head and said: "Xiaolin, I think it is not appropriate for you to choose two excavation points, from the perspective of coordinates, the terrain is a little high." For example, if the No. 3 excavation site is moved 20 meters west along Xinhua Street and excavated near the lowest-lying movie theater, is it more appropriate? ”

"Liu Gong, the terrain in the cinema is the lowest. But the underground network is also the most complex, with telecommunications, power cables, water pipes and heating pipes intricately intertwined. If it is a normal construction, we still have a way to avoid it, but now there is seventy or eighty centimeters of water on it, and the construction personnel can't see the situation below, and a little carelessness will cause huge damage. Although the site is slightly higher, there is no pipe network below, which will not cause any difficulty to the construction. Lin Yuanfang explained with a smile.

Liu Gong smiled, what he held in his hand was the drainage pipe network drawing, which was all marked with the drainage pipe network, and the telecommunication cables, power cables, water pipelines, heating pipes, etc. were not marked on the drawings, so he made a mistake of taking it for granted.

After Liu Gong was deflated, the other technicians of the construction committee closed their mouths tightly. In the face of the strong memory of the living archives, they are people who can't speak without drawings or ask fewer questions. can't be like Liu Gong.

Lin Yuanfang asked twice more, and when he saw that no one spoke, he turned his eyes to Hong Xianguo. Hong Xianguo exchanged opinions with Liu Hongwei, the county magistrate, and the deputy secretary and deputy county magistrate in charge of urban construction, and finally nodded and said: "Since everyone has no opinions, then let's implement this drainage plan." Next, please ask County Magistrate Liu to make specific arrangements for the division of labor......"

******

At half past one in the afternoon, the end of the tunnel leading to the Lao Niu River was opened.

At 1:45, five drainage points in the urban area were excavated at the same time.

At 10:00 p.m., the No. 3 drainage point was the first to open, and the turbid water rushed into the tunnel along the drainage point, making a huge noise, and surging towards the Laoniu River outside the city. In the vicinity of the drainage point, the rate at which the water level drops can be detected with the naked eye.

At 2:15 a.m., the No. 1 drainage point and the tunnel were opened......

At 2:17, the No. 5 drainage point and the tunnel were opened......

At 2:28 a.m., the No. 4 drainage point and the tunnel were opened......

At 2:34, the No. 2 drainage point, which was finally difficult to overcome, was finally opened!

After all five drainage points were opened, the water in the urban area rushed to these five drainage outlets, and the water level in the urban area dropped rapidly at a rate of 20 centimeters per hour.

By 6:40 p.m., except for a few low-lying areas where there was still a small amount of stagnant water, the stagnant water in the urban area was basically drained.

With great joy, Hong Xianguo reported the good news to Tian Jianjian, secretary of the municipal party committee, as soon as possible.

"Beautiful! Xianguo, well done! Tian Jianshe slapped the table again, "There is really a cadre team in Binan County who is good at fighting tough battles, and the municipal party committee has not mistaken you!" ”

The same slapped the table, but Hong Xianguo felt the different taste of ice and fire, and he continued to report: "Secretary Tian, although the stagnant water has been drained out, there is no way to eliminate the water traces on the building at once. Secretary Zhao will definitely see it tomorrow. I'm worried about ......"

"You're a fan of the authorities! Why should the water trail be removed? Not only can it not be eliminated, but Secretary Zhao must be invited to see it. Tian Jianshe said: "Xianguo, the draft of your report tomorrow will be changed, and you must focus on the heavy rain that is rare in a century in the early hours of this morning." In the face of such violent precipitation, the drainage system of your Nannan can quickly drain away the stagnant water, isn't this the best explanation of the achievements of the construction of small towns in Nannan? ”
