Research On Construction Survey Method Of Key Nodes In Airfield Project And Implementation Of Construction Organization Without Suspension

In view of the advantages of air transportation compared with other modes of transportation,airport construction has become an important measure for the development of regional economy in all regions of China.While building new airports,the relocation and reconstruction and expansion projects of existing airports are frequently launched,and the airport construction task is increasingly heavy.Surveying and mapping work runs through the whole life cycle of airport construction project and plays an extremely important role.In this paper,various survey technologies,methods,procedures and construction organization involved in the airport construction are studied in depth,and the construction survey and construction organization under the condition of non-stop flight in the flight area are deeply studied,and a complete and practical solution is put forward The application of chemical pavement paving system in airport construction is also studied,and some useful conclusions are obtained.The main work of this paper is as followsBased on the construction survey practice of several civil aviation airport airfield projects,this paper studies the measurement technology of key construction nodes involved in the construction of Civil Aviation Airport airfield from control point layout,review,encryption to pavement construction,and puts forward reasonable and feasible solutions.The construction method of independent coordinate system of civil aviation airport and the coordinate transformation method between the independent coordinate system and local coordinate system are completed.The methods of plane and elevation review of control points suitable for airport construction survey,the technical requirements and accuracy requirements of control network layout are summarized,and the methods and suggestions for the establishment and maintenance of permanent control network of civil aviation airport are put forward.Finally,the rationality and feasibility of the solution to the construction of the airport are presented.The construction of non-stop flight in the flight area is carried out after the flight of the airport,and the principle is two guarantees and two necessities.The two guarantees are to ensure the flight safety and normal operation of the airport,and to ensure the smooth progress of the construction without suspension.Based on the above principles,this paper studies how to reduce the waste of construction materials and improve the construction efficiency through the correct measurement method,combined with reasonable construction organization and scheme,on the premise of ensuring quality and safety,and puts forward feasible solutions.It provides valuable experience for construction survey and construction organization of non-stop flight in airfield,and also provides reference for similar construction projects.In this paper,the reasonable application of 3D digital pavement paving system in airport construction is compared,analyzed and verified.The operability,advantages and disadvantages of the system are analyzed,and the application scope of the technology is clarified,which provides reference experience for similar engineering construction projects and the application of this technology.
