It is worth noting that, compared with ordinary buildings, basement projects are developed and constructed in high-rise buildings. Due to the special location and environmental conditions of building basement itself, it is relatively difficult to carry out architectural design and construction.展开更多

With the rapid development of China's construction industry in recent years, people have put forward higher requirements for construction, of which the construction structure is an important part. China's prefabricated buildings are still in the development stage and are not perfect. There are defects in all aspects of the building, traffic conditions and construction technology have certain restrictions, and there are defects in the structural design. The most important thing is to improve the structural design.展开更多

However, accidents such as casualties and property losses still occur from time to time in the steel structure construction of architectural engineering. Therefore, in construction engineering, how to design the stability of steel structure is an urgent problem to be solved. This paper mainly analyzes the design principles based on the outline of steel structure design, and then probes into the stability and key points of steel structure design, in order to better enhance the stability of architectural engineering construction.展开更多

Prefabricated buildings, that is, their main components are prefabricated. Prefabricated components will be produced in the factory in a modular way. After the production is completed, they will be transported to the construction site, and they only need to be hoisted. Assembly can establish the concrete structure of the building and complete the construction of the building. The building will be divided into several units, some of the main components will be prefabricated in the factory, and will be transported to the construction site after the completion of prefabrication, and these components will be assembled and built. The prefabricated building mode is very different from the traditional construction mode. It has many advantages, more green and environmental protection, and adopts industrialized production mode and standardized production. Prefabricated building is the splicing of prefabricated components, which generally needs to reserve corresponding holes and positions for pipelines and equipment.展开更多

This paper proposed major characteristics of sightseeing farm design based on core connotations of behavior-driven design from the perspective of cognitive psychology. Cases were taken to analyze the design techniques of sightseeing farm, and it was concluded that sightseeing farm design based on behavior-driven perspective should orient to performancebased, refi ned, individualized and participatory from the four perspectives of highlighting functions, deepening the details, stressing originality, and optimizing experience, in order to provide new thoughts for solving existing problems of current sightseeing farm design.展开更多

In recent years, chemical engineering has achieved remarkable development under the effect of social and economic sustainable development. Not only has the industry productivity increased significantly, but also the chemical technology system has become more perfect and the industrial structure has become more and more huge. In the process of chemical production, chemical process piping is the key content and the main medium of material transmission. In chemical production, many materials have certain corrosiveness and danger, which have very strict requirements on chemical process piping. The design effect of piping system is related to the production efficiency and operation safety of chemical enterprises. Therefore, continuous optimization of chemical process piping design is needed to build a high-quality chemical process piping system, extend the service life of piping, and further promote the steady progress in the chemical field. This paper makes an analysis of this and puts forward some suggestions.展开更多

With the development of the city, the original planned sewage treatment plants located in the town edge or the suburbs are mostly gradually surrounded by new construction and development land, and the expansion is restricted. Underground sewage treatment plant has the advantages of land saving, environmental protection, small ground dirty gas and noise, and small impact on the ground landscape, which provides an effective way to alleviate the construction land shortage of urban sewage treatment plants in China. However, underground sewage treatment plants also have inherent disadvantages in flood control and drainage, such as entrance and exit, equipment lifting other exposed space, easy to cause flood pouring, becomes the key and difficult point of urban flood control and drainage;through the inlet pipe connected with urban sewage pipe network (or confluence sewage pipe network) overflow is easier to directly cause underground urban sewage treatment plant flooding, causing serious accidents and serious environmental pollution. Based on this, this article studies the key points and difficulties of structural design of underground sewage treatment plant for reference.展开更多

At present, some cities have not implemented complete urban water supply and drainage system planning and design in planning and construction, which has caused increasingly serious water resource waste and pollution problems, seriously restricted the long-term development of urban water supply and drainage system, and also restricted the long-term development of many areas of the city. Therefore, it is necessary to further improve the urban water supply and drainage planning and design, reasonably develop and utilize resources, meet the needs of social and economic development, and fundamentally promote the long-term development of modern cities.展开更多

The objective of spectrum allocation is to make efficient use of the spectrum while maintaining the transceiver synchronization on frequency and time in the network. The objective of resource scheduling is to guarantee the quality of service (QoS) requirements of different kinds of connections and to minimize the total energy consumption in the network as well. By sensing only a small set of possible channels in each slot based on the state transition probability of each channel, our spectrum allocation algorithm achieves high spectrum efficiency in the network. The resource scheduling problem is divided into three sub problems and we derive optimal solutions to these problems by greedy algorithm and convex optimization. The simulation results show that our algorithm can make efficient use of the spectrum and the network resources at a cost of low computational complexity.展开更多
