Abstract (597) PDF (4)
Abstract:
Dome roof is favored by designers all over the world because of its reasonable structural stress and smooth appearance. It is mostly used in industrial and civil buildings. However, compared with plane formwork, dome formwork has a three-dimensional change in space, so how to accurately determine the position and ensure the forming rules of arc surface formwork is the difficulty of dome formwork. Taking the roof formwork of the control tower dome of Mwanza airport as an example, this paper mainly introduces the formwork technology of the dome roof. In order to solve the problem of supporting formwork for the arcshaped bottom plate of the dome, CAD software was used to pick up the key data of arc length, diameter, height and radius of the dome in the electronic drawing. The arc rib was set out according to the corresponding size on the spot to assist the dome shaping. The arc rib was filled and fixed in different regions, and the short square timber and steel pipe frame were used as the support system under the formwork. The practice shows that this method has the advantages of simple operation, fast construction speed and good concrete forming effect.

Elementary Introduction to the Analysis of Surface Subsidence by Radar Remote Sensing Satellite Image Technology (SBAS)
XU Meng
2021, 3(1): 95-96.
Abstract (397) PDF (4)
Abstract:
In recent years, with the continuous development of urban construction, man-made or natural factors such as underground water extraction, subway construction, and volcanic eruptions have inevitably caused the settlement and deformation of the urban ground. Conventional methods of GPS measurement and precision leveling of land subsidence are difficult to meet the needs of large-scale and small-scale settlement of the urban ground. Synthetic Aperture Radar (InSAR) technology has the advantages of wide coverage, large range, fast data acquisition speed, monitoring of difficult-to-monitoring areas, and high monitoring accuracy. This provides a new method for urban land subsidence monitoring. However, studies have found that it is severely affected by time, space and atmospheric delays. PS-InSAR technology and SBAS technology have broken through this limitation, so they have played an important role in the work of urban land subsidence.

Analysis on the Technical Points of Intelligent Building Mechanical and Electrical Equipment Installation in the New Era
YU Gangcheng
2021, 3(1): 127-128.
Abstract (107) PDF (3)
Abstract:
With the rapid development of information technology and modern means, the society has entered a new period. With the popularization and application of intelligent technology, many social industries have made great progress and changes, which not only promotes the overall social and economic development, but also provides a more excellent development opportunity for China's construction industry. However, in the actual intelligent building mechanical and electrical installation process, due to the influence of various objective factors, it is easy to have problems in the installation. Therefore, in order to ensure the installation quality of intelligent building mechanical and electrical equipment, this paper first clarifies the work content of intelligent building mechanical and electrical equipment installation; secondly, carries out in-depth analysis on the problems existing in the installation of intelligent building mechanical and electrical equipment; on this basis, puts forward the technical points of intelligent building mechanical and electrical equipment installation in the new period, for reference.
