Research on Balance Device of UAV Aerial Photography Sur- veying and Mapping Instrument

This paper taking the UAV aerial photography mapper balance device as the research object, mainly research and design spiral balance device different from the more common one on the market. Setting a base and a sphere on the bottom of the UAV, when the aircraft is unstable in flight, the balancing device is coordinated with each other under gravity, so that the aerial mapper can maintain a stable position. The device allows the UAV to maintain torque balance in any harsh environment, thus ensuring photographic quality.

Construction Method of Swivel Bridge in Mountainous Area

This paper mainly introduces the construction of bridges by simple mechanical swivel construction method in mountainous areas. This construction method has the advantages of low construction cost, safe and reliable quality, no interference with traffic, no interruption of navigation, less damage to the environment, less construction cost and machines and equipment, and has good economic and social benefits.

Analysis on the Key Issues in the Process of Highway Engineer- ing Supervision

Highways connect various regions, allowing effective communication among various regions, and jointly speeding up China’s social and economic development. In the construction of highways, many problems will inevitably occur, which reflects the importance of highway engineering supervision and is also the most important content of the entire link. The paper focuses on the importance of highway engineering supervision and explores the key issues in the process of highway engineering supervision, and proposes solutions to related problems.

Irrigation Planning and Design of Farmland Water Conser- vancy Project

As an industry affecting the development of China’s livelihood, agriculture is also an important basis for comprehensively promoting the development of the national economy. Strengthening the construction of farmland irrigation project is an important guarantee to adapt to the industrial transformation and upgrading in the new period, so it must be planned and technically perfected. Under the guidance of the concept of green and sustainable development, the construction of farmland water conservancy projects should develop towards high efficiency and energy saving. Because there are still some problems in some areas such as insufficient understanding of technical concepts and unscientific project planning and design, this paper explores the necessity of construction optimization from the planning and design of farmland water conservancy projects, analyzes the design points, and continuously optimizes measures in combination with practical experience.

The Formulation of the Special Planning of Blue and Green Space System at County Level under the Background of Ter- ritorial Space Planning System

In recent years, the planning of blue-green space system has become a very important part of special planning in China’s municipal and county-level land spatial planning. It is not only the main measure for the overall requirements of China’s land spatial planning and the refinement and classification of blue-green space, but also the highlight in the process of reform and upgrading of spatial planning system, reasonable preparation is very important. Based on this, this paper puts forward some suggestions on the compilation of special planning of blue and green space system at the county- level under the background of territorial space planning system, in order to provide help for enhancing the compilation effect of relevant special planning.

Discussion on the Quality Control Measures of Automatic Welding in Southern Mountain Pipeline

The gas pipeline project of Guangxi Liquefied Natural Gas (LNG) project is the first automatic welding project in southern China. The welding quality is an important indicator to directly determines the construction quality of local pipeline welding, and also an important part of improving work efficiency. The implementation of the new process can bring great convenience to the work, improve the mechanical work efficiency, and achieve intelligent realization, not only saves the cost, but also standardize the automatic welding pipeline welding quality.

Reflection on the One-way Drainage System in Airport Flight Area

Airport drainage system is an important part of airport engineering, related to the safety and efficiency of airport operation. This paper introduces the role and composition of the airport drainage system, and details the design of the one-way drainage system in the flight area from three aspects: system design, application implementation and system advantages, and provides useful reference for the construction of civil aviation smart airport.

The Construction Technology of High Pier Verticality Control Based on Rapid Construction of Super High Pier in Mountainous Area and Unscented Kalman Filter

Based on engineering examples, the paper carried out research on the rapid construction technology of high piers in mountainous areas, and used unscented Kalman filter technology to eliminate the influence of measurement factors, man-made construction factors, and structural nonlinearities on the pre-deflection. The research results show that this technology can significantly improve the verticality of ultra-high piers in mountainous areas and has important application value.

Influence of Pavement Construction of Expressway Extension Project on Subgrade Settlement

In recent years, with the rapid economic development, the scale of highway construction has continued to expand, and the lack of scientific design and construction has led to roadbed settlement problems. The paper first expounds the principle of subgrade settlement, and then discusses the influence of pavement expansion technology on subgrade settlement with an example, hoping to play a certain role in the development of similar projects.
