Chapter 1351 Eliminating Concerns
In view of Zhu Daidong's high standards, strict requirements for Chuchuan Highway, and strict restrictions on the construction schedule, the construction of Chuchuan Highway will focus on the main focus, and multi-task points will be carried out at the same time. Under the premise of ensuring quality, the highway should be repaired as soon as possible on the whole highway line, with two Sometimes 200 meters is a construction section. Each construction section is combined with the culvert construction to organize parallel flow operation, sectional construction, layered filling, layered crushing, sectional molding in the rainy season combined with the subgrade filler to arrange construction, start a section of construction, the quality of the forming section of the highway is good, the most important thing is The subgrade plays a role in supporting the pavement. If the subgrade is not good, no matter how thick the pavement is and the proportion of cement is high, it is in vain. Once the subgrade collapses, the pavement will inevitably break. However, before the construction of the subgrade, the important thing is the drainage project. Water is one of Closely related to the immersion of the foundation to reduce the bearing capacity, the filling material is too wet, and the water content is higher than the water content, the difficulty of subgrade compaction is for the groundwater that affects the stability of the subgrade. Even if no specific plan is made in the design, it is necessary to propose engineering measures such as dredging, blocking, isolation Before the construction of the subgrade, we should first do a good job of cutting ditches, drainage ditches and blind ditches. In the process of filling the ground waterway embankment within the scope of road construction, each filling layer should be equipped with a drainage arch, and the ground rainwater should be removed in time to make a temporary drainage rapid trough to The combination of permanent drainage in the stage and the synchronous construction of the roadbed. During the construction process, special personnel are sent to carry out regular cleaning and maintenance. Starting from the drainage system and foundation treatment, Zhu Daidong will take part of the time to inspect the construction site every day. For how to build the road, Zhu Daidong is now half an expert. He is familiar It is stronger than some construction workers and engineers. This time, for the construction of Chuchuan Highway, Zhu Daidong did not mobilize the masses as he did in Yuhuā County and Furong County. He only invited 100 quasi-professional amateur supervisors from Furong County. With the cooperation of Muchuan and the provincial supervision department, he made every effort to ensure the Chuchuan In fact, as long as the municipal government's funds are in place, there is not much conflict with the construction company under the city investment company in terms of interests. No one wants to deliberately repair a bad road, and the friendly army will also come to the construction site every day. He is the general commander of the Chuchuan highway project, which is also the first high-standard highway He attaches no less importance to this than Zhu Daidong's "the progress of clearing the meter of the friendly mayor's roadbed is a little slow," Zhu Daidong said. Every time he comes to the construction site, in addition to having to look at it in person, he also communicate with the construction personnel on the site. From them, Zhu Daidong can get first- The voice of front-line workers, whether it is true or false, makes him gratifying that whether it is ordinary workers who report the situation to him, supervisors or business supervisors from Furong County, they are very serious about their work and sincerely communicate with themselves, especially the 100 amateur supervisors from Furong County, although he Our amateur theoretical level may not be as good as professional supervisors, but they work conscientiously and have certain practical experience. The most important thing is that the Muchuan Municipal Government has issued a professional customized construction technical specification to each of them. What needs to be paid attention to at each stage, they can strictly supervise in accordance with the above requirements. The supervisor said, "Yes, there is no old roadbed on the Chuchuan Highway, so it takes more time in this regard, but sharpening the knife does not miss the woodcutter. This period of work is done well, and the future work will be meaningful." Shi Youjun said. He knew that Zhu Daidong presided over the construction of the highway when he was in Yu It was only a county-level highway, but the quality of the highway was no less than the friendly army at that time. At that time, he also went to these two places to inspect. It was Zhu Daidong who accompanied him to report the work, but in a blink of an eye. Now it's his turn to report to Zhu Daidong's work. It's The planting soil on the surface contains all kinds of grass roots and organic impurities, which are easy to rot over time, causing the subsidence of the subgrade. Therefore, all the tree roots within the topsoil high highway and the first-class highway subgrade of the filling section should be removed from the filling section and the original ground of the excavation section. After cleaning the surface For strength and stability, it is necessary to choose soil and stone with good local stability and a certain strength as the subgrade filler as possible. Sludge, marsh soil, permafrost, organic soil, turf soil, domestic waste, tree roots and soil containing humus that affect the strength of the roadbed salted soil, loess, expans It is necessary to restrict the use of Chuchuan Highway, which is an open line. When designing, the shortest distance is used. This highway has to pass through farmland, woodland and part of grassland, so the requirements for the roadbed are very strict. "Yes, Chu has a good saying that everything is almost three minutes, no matter what, if it violates the objective law. There must be only fraud. We should also pay special attention to the water content of the grass-roots level. In this season, it is the best time to build a road." Zhu Daidong nodded slightly. His request for Shi Youjun is that under the premise of ensuring the quality first, if there is no quality, what's the use of the progress no matter how fast the
Compaction when the optimum water content of the soil is compacted can not only reduce the compaction power, but also the highest degree of density. During the construction process, the moisture should be evaporated. Therefore, the content of natural soil should be carried out when the water content is greater than one to 2% of the optimal compaction water content. The water content is often close to the optimal water content. At this time, machinery should be arranged. After filling the soil, it should be paved and crushed to prevent water evaporation. During the construction in the rainy season, the water content of the soil is larger than the optimal compaction water content. At this time, the soil should be spread out to dry to make the water evaporate In the cool autumn season, the weather is neither cold or hot. If you have to work overtime at night, there is no problem. Of course, if the natural water content is insufficient, you need to add water. You can sprinkle water with a water truck after the first leveling, mix it with mixing equipment and crush it evenly, or water the surface of the soil collection pit one The latter method of evenly infiltration into the soil is low-cost, the water content is uniform, and the effect is good. "Yes, we will strictly follow the technical specifications. All construction personnel have a unified understanding of this," Shi Youjun said. This road is related to the economic development of Muchuan, and the municipal government has all the funds at one time. In place, the city investment company is completely unnecessary, and it will not play tricks on the quality. "I remember that there is a rice field in front of me, and we should pay special attention to the roadbed in the rice field area." Zhu Daidong told me that although the Chuchuan Highway is only in the stage of building the roadbed, he is basically clear about all the Where there are curves, where there are rice fields, and where there are forest areas, he is clear. "Yes, for the precautions in the rice field area, not to mention the construction personnel below, even I am very familiar with it," Shi Youjun said. Although he used to be the leader of Zhu Daidong, now he is very sure of his current position. It is clear that in a more private place, it has nothing to do with Zhu Daidong to joke, but once he enters the public place, he will definitely put his job first. Zhu Daidong is the acting mayor. He is the executive deputy mayor, and the executive deputy mayor is the mayor's main assistant. This view is always engraved in his mind about the problem of the road Daidong mentioned many times at the meeting, especially for the construction of sections such as rice field areas, subgrade compaction, loess construction, expansion land areas, etc. This highway is the first large-scale project proposed after Zhu Daidong went to Muchuan, and there is no external bidding, which makes Zhu Daidong bear a lot of pressure. Shi You The pressure that the military should bear is no less than Zhu Daidong's current city investment company, which will soon become a giant. In addition to this Chuchuan highway, the city investment company will also undertake the construction of 150 hospitals. At the same time, the city's public transportation is free of charge. For the management of the city's public transportation company, it also attracts If the friendly army was a little negligent, he believed that rumors about himself would soon spread, and his energy and ability were slightly inferior to Zhu Daidong. Therefore, the efforts he needed to make were unimaginable to ordinary people. Although he was the executive deputy mayor of Muchuan, since the construction of Chuchuan Highway began, he has been The working time is not less than 12 hours, even on weekends. For the construction technical specifications issued by the municipal government, in fact, he is also familiar with it. "Oh, friendly mayor, can I ask you a question? How to deal with the suitable rice field area with over-wet soil? Zhu Daidong said with a smile that he knew that Shi Youjun had worked very hard during this period. Every night, the Youjun had to stay in the office until after ten o'clock, and Shi Youjun was now thinner and darker than when he first came to Muchuan. "The paddy field often cannot be filled directly because of the excessive water content of the dirt field, Ash reduces the water content of wet soil, improves the plasticity of the soil, and the dosage of lime can be determined by experiments. In order to achieve a good sanding effect in construction, there are also two methods of ash. In the construction of filling, we should follow the principle of thin filling and fast pressure. You are anexperitus in this regard. I'm Shi Youjun smiled and said, "Mayor of Youjun, it seems that I don't need to worry about Chuchuan Highway anymore." Zhu Daidong said with a smile. He knew that Shi Youjun attached great importance to Chuchuan Highway, but he didn't expect that his attention would be so high (to be continued)
