Keywords: highway construction; transportation; advantages; construction problems
The quality of road construction is affected by many aspects such as roadbed and pavement. Therefore, in order to achieve smooth construction of roads and promote the development of the transportation industry, it is necessary to actively explore related construction issues and continuously improve the overall road construction through deepening understanding of road construction. Level, realize the multi-faceted development of highway construction. In addition, it is necessary to formulate road construction and construction strategies in time to strengthen the overall management level of road construction, so as to give full play to the development advantages of road construction in transportation. Based on this, the following mainly briefly describes the advantages of highway construction in transportation, and analyzes the construction problems existing in the construction process, and further proposes relevant solutions.
1. Advantages of highway construction in transportation
(1) Flexible, convenient and adaptable
Road transportation can not be limited to a certain area, especially for some remote areas, if it is difficult to transport by rail and other forms, road transportation will avoid this situation, and can effectively strengthen the communication between remote areas and the outside world, and then promote economic development. At the same time, the road network is broader and the mobility is stronger in the transportation process. Access can effectively ensure the connection between the various links of road transportation and ensure that the road construction is more standardized and reasonable.
(2) Short transportation time and direct arrival
Because automobile transportation is more flexible and its volume is smaller, the goods can be directly transported to the designated location during the transportation process, and at the same time, it does not need to perform other work, and can be transported directly. In addition, road transportation is more convenient in transportation, and it can be reached directly without transit, so its timeliness is stronger and the transportation speed is faster.
(3) Less capital investment
Compared with other modes of transportation, road transportation can require less capital investment than others, thereby reducing its transportation pressure. At the same time, transportation requires simple facilities, lower vehicle costs, and a more convenient way of buying. The rate of return on investment is correspondingly higher. Moreover, under the normal operation of road transportation, investment in road transportation can achieve one to three turnovers within a year, while turnover in other transportation industries requires multiple turnovers.
2. Construction problems existing in road construction in transportation
(1) Subgrade problems in highway construction
Highway subgrade determines its overall quality. If the foundation construction cannot reach a certain strength, it will affect the overall quality of highway construction, and once the foundation collapses, it will destroy the aesthetics of the road surface and affect the safety performance of highway construction. However, in the actual construction process, the subgrade compaction still does not meet the standard, and the road surface will be deformed, or the rolling operation is not carried out in accordance with the actual construction requirements, making the overall foundation uneven and the compaction effect is not good. In addition, the roadbed slopes are also scoured from time to time. Under normal circumstances, the roadbed is damaged for a long time, and its water seepage performance is poor, which in turn causes scouring problems.
(2) Pavement problems in highway construction
Asphalt is generally used as the road surface during the paving process of highway pavement. However, improper laying will cause cracks in the road surface. Cracks are divided into horizontal cracks and longitudinal cracks. The causes of longitudinal cracks are caused by improper paving of the entire pavement. The second is that the road surface smoothness is also one of the common problems. The reason is mainly due to the irregular operation of the equipment during the construction process, especially the low level of mixing technology will seriously affect the smoothness of road construction. In addition, during the paving process, the construction personnel did not carefully check the existing problems, which led to many detailed problems not being discovered in time, resulting in unevenness of the construction road surface and affecting the overall quality of road construction.
(3) Highway construction management issues
Road construction projects are cumbersome and numerous, which will lead to the gradual strengthening of construction management during the construction process, which in turn affects the situation of highway construction. First of all, the construction design management is not standardized. In the highway construction design stage, if the work is not completed within the scope of the specification, the construction quality will not be guaranteed, and the various construction links will be confused. Secondly, the management mode of highway construction needs to be enhanced. It still adopts a more traditional management mode, which does not integrate the actual development needs of the current highway construction. At the same time, because the highway project construction is more complicated, simple management mode cannot guarantee the construction of the project. Finally, the overall safety awareness of road construction is low, and road construction must ensure the safety of every construction worker, but on-site safety management is still not standardized enough, and illegal operations occur from time to time, which leads to engineering accidents.
3. Relevant solutions for road construction in transportation
(1) Strengthen foundation drainage performance and improve foundation protection
Highway construction must ensure the drainage performance of the foundation, strengthen the drainage performance of the ground, and use drainage pipes and side ditches to enhance its drainage. To ensure the underground drainage, it can adopt the function of permeable drainage, and use methods such as infiltration ditches to improve its drainage capacity. It is necessary to improve the foundation protection work. The slope of highway construction will protect its slope surface. The slope will be protected by planting grass and concrete prefabricated blocks. In order to prevent the roadbed from being washed by river water, protection work will be carried out to ensure that the highway foundation can meet the actual situation. Construction needs to ensure the quality of road construction.
(2) Reasonable selection of construction materials to improve road surface smoothness
In the process of highway construction, it is necessary to ensure that the construction materials can meet the standards of highway construction. Pavement materials determine the appearance and quality of the highway. The construction unit should choose construction materials suitable for the pavement, such as construction materials with small particle size and voids, so as to effectively improve the impermeability of the asphalt pavement. At the same time, it is necessary to actively strengthen the design of pavement thickness, and reasonably select suitable construction techniques to make the road surface deflection and thickness meet the standards. The second is to improve the smoothness of the pavement. In this process, it is necessary to ensure that the construction of the pavement base layer can follow the actual construction specifications, and the maintenance of the foundation must be strengthened. Then the construction unit must use water spray to maintain the road.
(3) Improve employees' safety awareness and realize highway quality management
Highway construction is inseparable from safety management. Only by continuously improving workers' awareness of safe construction can the operation of highway construction be effectively promoted. This requires all road construction staff to keep in mind the importance of safe construction, and the construction unit should also carry out relevant safety management training in a timely manner, so that the road construction staff can clarify the safety issues in the road construction process, learn relevant risk prevention knowledge, and then Reduce potential safety hazards during the construction process. At the same time, in order to ensure the quality of highway construction, it is necessary to strengthen its quality control, starting from the two aspects of construction process and raw material procurement, continuously improving its construction technology level, and ensuring that highway construction materials can meet relevant standards. In addition, it is necessary to strengthen the professional skills of various road construction personnel to ensure that they can use professional technology to continuously improve the quality of road construction, ensure that the road can meet the use standards when it is put into use, and further promote the development of my country's transportation industry.
Concluding remarks
In summary, the development of highway construction plays an important role in transportation. It can not only realize the coordinated development of various regions, but also realize direct transportation. With the rise of the economic level, the number of private cars has gradually increased, which puts higher and higher requirements on the quality of road construction. Therefore, the construction unit must continue to strengthen the quality of road construction and actively improve the overall level of road construction. In the actual construction process, it is necessary to continuously strengthen the drainage function of the foundation, rationally select road construction materials, and then actively improve the safety awareness of employees, ensure that the road construction can meet the actual needs, realize the efficient development of road construction, and continuously improve the comprehensive level of the transportation industry.
