In view of Zhu Daidong's high standards and strict requirements for the Chuchuan Highway, as well as the strict restrictions of the construction schedule, the construction of the Chuchuan Highway will be the main focus, and multiple tasks will be carried out at the same time. Start a section, form a section of the quality of the highway is good, the most important thing is to see whether the roadbed can be repaired, the solid roadbed plays a role in supporting the pavement, if the roadbed is not good, then the road surface is thicker, no matter how high the proportion of cement is, it is also in vain Once the roadbed collapses, the road surface will inevitably break Chapter 1351 to eliminate concerns (ask for a monthly ticket) Crack but before the construction of the roadbed, the important thing is the drainage project, water is one of the main factors in the formation of subgrade diseases, The strength and stability of the subgrade are closely related to the water soaking of the foundation to reduce the bearing capacity, the filling material is too wet, and the water content is higher than the water content, and the subgrade compaction is difficult for the groundwater that affects the stability of the subgrade, even if the design does not make a specific plan, it is necessary to put forward engineering measures such as dredging, blocking, and isolation to reduce the groundwater level or guide to the subgrade outside the scope For surface water, the subgrade should first do a good job of intercepting ditches, drainage ditches, and blind ditches before construction. Truncation and neglect of the ground water embankment within the scope of road construction, in the process of filling each fill layer to set up a drainage arch, timely removal of ground rainwater, higher fill to do temporary drainage rapid flow groove, to prevent rainwater erosion of the embankment slope during the construction of the temporary drainage to be combined with the permanent drainage in the operation stage, synchronous construction of the roadbed, in the construction process to send special personnel to carry out regular cleaning and maintenance, starting from the drainage system and base 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, and his familiarity with some theories is stronger than that of some builders and engineers This time for the construction of the Chuchuan Highway, Zhu Daidong did not mobilize the masses as Chapter 1351 to eliminate concerns (ask for a monthly ticket) in Yuhuā County and Furong County, but only invited a hundred quasi-professional amateur supervisors from Furong County, with the cooperation of Muchuan and the supervision department in the province, to ensure the quality of the Chuchuan Highway, in fact, as long as the municipal government's funds are in place, There is not much conflict with the construction company below the urban investment company in terms of interests, no one wants to deliberately build a very poor road, and the friendly army will come to the construction site every day, he is the commander-in-chief of the Chuchuan highway project, which is also the first high-standard highway he presided over after he arrived in Muchuan, he attaches great importance to this Cheng dù is no less than Zhu Daidong, "the friendly mayor of the roadbed is a little slow," Zhu Daidong said, every time he comes to the construction site, in addition to seeing it in person, he also has to communicate with the construction personnel on the site, From them, Zhu Daidong can get first-hand information, and he can judge the voice from the front-line workers at that time, whether it is true or false, what makes him happy is that the ordinary workers who report to him, the supervisors, or the business supervisors from Furong County, they are very serious about their work, and they are also sincere to communicate, especially the 100 amateur supervisors from Furong County, although they are amateur theoretical level may not be as good as professional supervisors, but they work hard, There is also a certain amount of practical experience, and the most important thing is that the Muchuan Municipal Government has issued each of them a professional customized construction technical specification, what matters need to be paid attention to at each stage, they can follow the above requirements, strictly supervise the implementation "Yes, Chuchuan Highway does not have an old roadbed, so it takes more time to grind the knife in this regard, but the sharpening knife is not mistaken, and the woodcutter, this work is done well, and the future work will be meaningful" Shi Youjun said, he knew that Zhu Daidong had presided over the construction of roads when he was in Yuhuā County and Furong County, Don't look at the construction of only the county-level highway at that time, but the quality of the highway, no less than the national highway at that time, the friendly army still remembers, he also went to these two places to inspect, it was Zhu Daidong accompanied to report to him but in a blink of an eye, now it is his turn to report to Zhu Daidong, life is like this, it is also very miraculous The planting soil on the surface of the ground contains a variety of grass roots and organic impurities, which is easy to rot for a long time, causing subsidence of the roadbed, so the original ground of the fill section and the use of the excavation section should be cleared of the topsoil high highway, The roots of the tree within the scope of the roadbed of the first-class highway should all be dug up, the pits should be filled and tamped, and the surface should be leveled and compacted to ensure the strength and stability of the embankment, and the soil and stone with good stability and certain strength should be selected as the subgrade filler as far as possible, and silt, swamp soil, frozen soil, organic soil, turf soil, domestic garbage, tree roots and soil containing humus that affect the strength of the roadbed, saline soil, loess, expansive soil, and poor stability after rolling and forming. To limit the use of the Chuchuan highway is a opened line, in the design, the shortest distance to be used, the highway to pass through farmland, woodland and a part of the grassland, so the requirements for the roadbed are very strict" Yes, Chu has a good saying, things are fast and three days off no matter what, if the objective law is violated, it must only be fake, and special attention should be paid to the water content of the grassroots level, now this season, it is the best time to build the road" Zhu Daidong bowed slightly, his requirements for the friendly army of the time were, On the premise of ensuring quality first, what is the use of talking about progress if there is no quality, no matter how fast the progress is?

Compaction is carried out when the best water content of soil compaction can not only reduce the compaction power, but also the highest compaction process in the construction process of water to evaporate, so that the water content is greater than the best compaction water content in one to two percent for the water content of natural soil is often close to the best water content, at this time should be arranged machinery, paving and rolling immediately after filling the soil, to prevent water evaporation in the rainy season construction, the water content of the soil is larger than the best compaction water content, at this time the soil should be spread out to dry, so that the water evaporation, And detect the water content at any time, compaction at the best water content is now the season of high and cool autumn, the weather is not cool or hot, if you want 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 waterwheel after paving the initial leveling, mix evenly with mixing equipment and roll it, you can also take the surface of the soil pit in the soil taking field one day in advance to water water to make it evenly infiltrate into the soil, the latter method is less costly, and the water content is uniform, the effect is better" Yes, We will strictly follow the technical specifications to carry out, for this point, all the construction personnel have a unified understanding" Shi Youjun said, this road is related to the economic development of Muchuan, and the municipal government will put all the funds in place at one time, the city investment company is completely unnecessary, and will not play huā in terms of quality "I remember that there is a rice field area in front, and special attention should be paid to the roadbed in the rice field area" Zhu Daidong advised, although the Chuchuan Highway is still only in the stage of building the roadbed, but he has all the conditions of this road, Basically, he already knows where there are curves, where there are rice fields, where is the forest area, he knows it well, "Yes, for the precautions in the rice field area, don't say the construction personnel below, even I am already very familiar with it" Shi Youjun said, although he used to be the leader of Zhu Daidong, but now he has a very clear grasp of his current position, in a more private place, it has nothing to do with joking with Zhu Daidong, but once he enters the public place, he definitely puts his work first Zhu Daidong is the acting mayor, He is the executive vice mayor, the executive vice mayor is the mayor's main assistant, this point of view is always engraved in his mind for the problem of the roadbed, Zhu Daidong has mentioned many times at the meeting, especially for the construction of such areas as rice fields, roadbed compaction, loess construction, expansive land area, etc., special attention to this highway is the first large-scale project proposed by Zhu Daidong after he arrived in Muchuan, and there is no external bidding, which makes Zhu Daidong bear a lot of pressure Correspondingly, the pressure that the friendly army has to bear, Not inferior to Zhu Daidong's current urban investment company, will soon become a behemoth, in addition to this Chuchuan highway, the city investment company will soon undertake the construction of one hundred and fifty hospitals, at the same time the city's public transport is free, for the management of the city bus company, but also at any time to attract people's attention, if the friendly army is a little negligent, he believes that rumors about himself will soon spread, and his energy and ability are slightly inferior to Zhu Daidong, therefore, he needs to pay for the effort, It is unimaginable to ordinary people, although he is the executive vice mayor of Muchuan, but since the start of the construction of Chuchuan Highway, his daily working hours have not been less than twelve hours, even on weekends, so for the construction technical specifications issued by the municipal government, in fact, he has also turned over the melons and "Oh, friendly mayor, can I ask a question?" What should be done with suitable paddy fields with wet soil? Zhu Daidong smiled and said that he knew that Shi Youjun was very hard during this time, and every night Shi 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. In the construction of filling, we should follow the principle of thin filling and fast pressing Mayor Daidong, you are an expert in this area, am I right? Shi Youjun smiled and said, "Mayor Youjun, it seems that I don't need to have any worries about the Chuchuan Highway anymore" Zhu Daidong said with a smile, he knew that Shi Youjun attached great importance to the Chuchuan Highway, but he didn't expect that his attention would be so high (to be continued)!!
