First, establishing a sound highway maintenance management system is the basis for doing a good job in maintenance management.
System is the norm to regulate all work and people's behavior. A good set of rules and regulations can make the work of various departments connect normally, avoid mutual wrangling, prevarication and negligence, and get twice the result with half the effort. A unit is like a running machine, and everyone is every part of the machine. To make the whole machine work normally, it is necessary to ensure the normal work of each component. Throughout the well-known enterprises at home and abroad, a series of practical rules and regulations have been formulated according to their own characteristics. As the saying goes, "No rules, no Fiona Fang" fully illustrates this point. What systems should be established? I think it should be considered from the following aspects. First, it covers every job, every step and every post within the scope of work. Second, it is easy to operate and execute, concise and frightening. Third, everything should proceed from reality. I think at present, we should formulate highway maintenance project quota and compilation method, highway maintenance quality inspection and evaluation standard, highway maintenance management inspection and appraisal method and standard, and highway maintenance management manual, and make detailed daily original records, such as highway patrol diary, maintenance work diary, abnormal weather record, road property damage record, maintenance project diary, technical investigation record, etc. There are road survey records, bridge regular inspection records, traffic survey records, bridge and culvert siltation (scouring) observation records, pavement longitudinal and transverse joints observation records, bridge expansion joints observation records and so on. The purpose of making these original records is to timely and accurately record the relevant situation in expressway and expressway, analyze, summarize and find out the laws, so as to "prescribe the right medicine" and lay a good foundation for "preventive maintenance", and finally achieve early detection, early prevention, less expenditure and good results. Treat diseases in the state of tooth eruption. Get the maximum benefit with less investment.
In China, expressway has gone through more than ten years. Therefore, establishing rules and regulations and standardizing management should be put on the important agenda, otherwise, the benefits of expressway will not be brought into full play.
Second, we must take the road of mechanized maintenance.
The inherent nature of expressway itself determines that it must be repaired in time after being damaged, especially when the pavement is partially damaged, which can easily lead to traffic accidents. It is an important duty of highway maintenance management department to provide good road conditions for road users at all times. In the past, manual maintenance, four-wheel transportation and experience management can no longer meet the needs of maintenance management in expressway. Therefore, it is necessary to cultivate a mechanized maintenance team with quick response, skilled technology and complete equipment to ensure the timeliness and rapidity of maintenance.
The company is mainly responsible for road overhaul and special engineering maintenance, and has a highway engineering operation team: responsible for subgrade, pavement, bridge and culvert, protection and river maintenance and emergency repair; Housing maintenance engineering team: responsible for the maintenance of water, electricity and heating; Traffic engineering group: responsible for the maintenance of pavement markings, signs, collision barriers, isolation barriers, toll collection, communication and monitoring systems. The company has an engineering department: responsible for issuing production tasks, quality inspection and engineering quantity audit. The Planning and Finance Department is responsible for the annual plan, capital expenditure control and final accounts of the project. General department: responsible for daily administration, logistics, personnel, labor and other work.
In terms of mechanical equipment, special machinery must be given priority to, such as washing planer, roller, paver, mixing building, etc. Non-special machinery such as dump trucks can be solved by social vehicles. It is understood that there is a surplus of social vehicles at present and they can be rented at any time. In order to reduce the upfront investment of excessive funds and reduce the management cost and difficulty.
In the end, the road pits and grooves can not be repaired overnight, and the anti-collision guardrail can not be repaired in a few days. When you hear the command, you can quickly dispatch and complete the parking, so that the closure rate of expressway is "zero".
Third, improve maintenance management technology.
Advanced and applicable maintenance technology ensures the normal use of high-grade highways, and standardized, scientific and efficient management continuously improves the service level of high-grade highways. High-grade highway maintenance management facing 2 1 century must have strong technical support.
(1) Using GIS-T to promote the modernization of highway maintenance management. Because the traffic geographic information system can digitize and visualize the spatial information, through powerful software, the three-dimensional spatial analysis along the highway is intuitive and concise, and the data management is convenient and efficient, which provides a large number of timely and accurate data information for highway maintenance and operation, and provides a basis for the development, scientific management and decision-making of highway traffic.
(2) Using high-tech detection technology to promote the intelligentization of engineering quality monitoring and highway maintenance, and using high-tech means such as high-precision sensors, radar technology and rs technology to realize the transformation from manual detection to automatic detection.
(3) Promote the use of new technologies, new materials and new processes suitable for foreign high-grade highway maintenance, improve pavement durability and prolong highway service life.
At present, modified asphalt technology, SMA pavement technology, geosynthetics, emulsified asphalt, slurry seal and so on. Widely used in the construction of high-grade highways in China, all developed in the process of highway maintenance in developed countries. Their popularization and use have improved the stability and durability of highway bridges and other buildings, and achieved the purpose of saving energy, reducing costs and realizing the sustainable development of highway traffic.
Four. abstract
The functions and characteristics of high-grade highways determine the importance and particularity of high-grade highway maintenance management. How to do well the maintenance and management of high-grade highways is a long-term and arduous task for highway management departments and operating enterprises. It is the fundamental starting point for us to engage in highway maintenance management to correctly establish the view that "highway construction is development, highway maintenance is also development, and it is a more important development". According to the requirements of establishing a socialist market economy in China, in order to meet the public welfare of high-grade highways and the commodity attributes of socialized mass production, it is necessary to study modern highway maintenance management countermeasures from the height of highway sustainable development strategy, deepen the reform of existing highway maintenance system and operation mechanism, and embark on a new road suitable for the continuous progress of China's highway industry.
