Talking about the problems and solutions of highway construction survey Abstract: Highway construction survey runs through the whole process of highway construction, which is of great significance to ensure the quality and safety of engineering planning, design and construction. Key words: highway construction problems and solutions 0 Introduction All stages of highway construction need to be measured, and the accuracy and speed of measurement directly affect the quality and progress of the whole project. Highway engineering construction survey runs through the whole process of highway construction, which is the prelude, ending and chord of the main theme of highway construction. Therefore, highway engineering survey is of great significance to ensure the quality and safety of engineering planning, design and construction. According to many years of experience in infrastructure management, highway construction survey obviously cannot meet the needs of highway development situation. Most highway construction enterprises do not realize the importance of construction survey in modern highway construction, and despise the organization, management and investment of construction survey. 1 There are the following problems in highway construction survey: 1 1 The quality of surveyors is poor and there are few people. Some highway construction enterprises do not have full-time construction surveyors, and most of them are part-time technicians (builders) during the construction process. These amateurs, who lack special training and have a little knowledge of the performance, operation and design methods of conventional measuring instruments, are simply not competent for construction survey and cannot guarantee the quality of construction survey. 1.2 measuring instruments and equipment are backward. A considerable number of construction enterprises do not have enough measuring instruments, and even many construction enterprises do not have measuring instruments. Due to the backwardness of measuring instruments in construction, the accuracy of measurement is seriously affected. Moreover, the lack of instruments also affected the construction progress. 1.3 improper operation of measuring instruments and inadequate warranty. Generally speaking, instruments used for measurement are precision instruments. In the process of use, due to the limited level of measuring personnel, the correct operation method was not strictly followed, which reduced the sensitivity of measuring instruments. In addition, the instrument was improperly damaged because it was not put into the box for protection in time after use. 1.4 measurement quality control is not in place, and the quality of highway engineering is monitored. The existing system is that government supervision and social supervision participate together, and qualified construction units and their own engineering supervision departments take a three-pronged approach. However, in the actual project quality monitoring and project completion acceptance, we only pay attention to the inspection and control of other construction quality, while ignoring the inspection of construction measurement quality. Many engineering acceptance supervision departments went to the site to have a look and went through the motions, but failed to personally measure with instruments. The acceptance of a few projects only stays in the recheck of highway centerline elevation, and it is impossible to fundamentally monitor the quality of construction survey. This phenomenon misleads the managers of highway construction enterprises and thinks that highway construction survey is not important, which is not conducive to the improvement of highway construction survey level. In view of the above problems in highway construction survey, the following measures can be taken to solve 2. 1 change the concept, and fully realize that the backward concept of highway construction survey in modern highway construction is the biggest obstacle to the reform and development of any cause. Highway construction survey workers should completely abandon the concept of low-grade quality and establish the idea of "quality first": fully understand the important role of highway construction survey in highway construction with a development perspective; There should be a sense of crisis and urgency to change the current situation of highway construction survey and improve the level of highway construction survey; Change ideas, strengthen the leadership, supervision, organization and management of highway construction survey, and give full play to the role of highway construction survey in modern highway construction. 2.2 Increase the investment in measuring instruments to lay a material foundation for improving the level of construction measurement. At present, the scale of highway engineering is expanding day by day, and the requirements for construction technical accuracy are getting higher and higher. Therefore, in highway engineering construction survey, the original survey methods and three means have been greatly impacted, and some will be eliminated. Managers of highway enterprises should have a development vision, combine their own development needs, introduce practical new instruments as soon as possible, improve the quality of highway construction survey, and meet the needs of rapid, efficient and high-quality construction of modern highway projects. 2.3 Strengthen the construction of highway construction team and ensure the quality of construction surveyors. With the expansion of highway scale, the continuous improvement of engineering quality requirements, and the development and application of new surveying technologies and instruments, effective measures must be taken to strengthen the construction of highway construction team and improve the quality of construction surveyors. Managers of highway enterprises should establish the concept of "people-oriented" and give full play to "people are the most active factor in production". Highway construction surveyors should strive to improve their professional quality through self-study and training: mainly master the performance, operation, maintenance and maintenance of conventional surveying instruments and tools; Master the common lofting methods and skills in construction survey; Master the development and application trends of new measurement technology and carry out creative practice. In addition, construction surveyors must have a high sense of responsibility, be hardworking and strive for perfection. Under any difficult and complicated conditions, the quality of measurement results must be guaranteed. Otherwise, a little carelessness will cause great losses to the country and people. 2.4 Strengthen construction supervision and control, and promote the improvement of construction survey level. In the process of monitoring the construction quality of construction projects, construction supervisors should effectively incorporate the inspection and acceptance of construction survey results into their daily supervision work. In the quality monitoring of four pairs of construction survey, we must adhere to the principle of "control in advance" and strengthen the monitoring of construction survey. For the main construction survey lofting, it is necessary to carry out retest, and it is best to strengthen the verification work through various methods. Only when the measurement results are qualified can the next process be carried out. In addition, the construction survey results can be used as technical data for project completion acceptance and project quality grade evaluation after being tested by the supervisor and signed by the surveyors of both parties. Strengthening the monitoring of highway construction survey can effectively put an end to engineering quality accidents, which is conducive to improving the quality of survey managers and the level of supervision survey in highway enterprises. With the rapid development of science and technology and economy, highway theory and technology are becoming more and more perfect. The style, form, space and function of highway will undergo profound changes and continue to extend.
