Civil engineering; Sustainable development; study
At present, various constructions in our country are carrying out sustainable development, aiming at realizing the harmonious development between man and nature. For civil engineering activities, the application of the concept of sustainable development in the process of civil engineering implementation is extremely important, so the construction unit must attach importance to the formulation of the sustainable development plan of civil engineering and implement the concept of sustainable development in the whole process of civil engineering implementation.
A, the preparation of civil engineering design
The design scheme of civil engineering affects the implementation of sustainable development of civil engineering to a great extent. Only a scientific and reasonable design scheme can ensure that the idea of sustainable development is fully reflected in the implementation of civil engineering and reduce unnecessary waste of resources. The so-called civil engineering design is mainly aimed at the comprehensive analysis of economy, resources, technology and environment in the process of civil engineering implementation, and finally forms a behavior plan suitable for the sustainable development of civil engineering. In the process of compiling the civil engineering design scheme, the compilers must make full investigation and study to ensure the economy, science and feasibility of the design scheme.
First of all, in the process of civil engineering design, designers must pay attention to the technical connection between preliminary design, technical design and construction drawing design, and keep in touch with the structure and internal equipment design of civil engineering buildings. The improvement of the concept of sustainable development of civil engineering designers will greatly enhance the sustainability of civil engineering buildings. For designers, in order to improve the sustainability of civil engineering design, designers must strengthen comprehensive knowledge learning, improve their knowledge and understanding of building engineering materials, new technologies and new materials, and learn to design civil engineering from the aspects of resources and environmental protection. In addition, in the actual design process, in order to ensure the implementation of the principle of design sustainability, different design departments should strengthen contact and achieve coordination and unity. For conflicting design projects, we should strengthen exchanges and communication with each other. Through scientific and comprehensive investigation and study, the scientific and sustainable design scheme is determined, and the scientificity of civil engineering design scheme is continuously improved.
Secondly, designers of civil engineering buildings should pay attention to the sustainability of civil engineering construction and use on the one hand, and ensure the quality of civil engineering on the other hand. The quality of civil engineering is the basis of scientific and reasonable design scheme. Designers must ensure the design standards and parameters in the design scheme, which can not only meet the environmental protection, economic and aesthetic requirements of civil engineering buildings, but also ensure the quality of civil engineering and enhance the safety and reliability of civil engineering. Therefore, civil engineering designers should fully combine the actual situation of the construction site, choose construction methods that are conducive to the implementation of scientific development and make full use of various renewable resources before compiling the design scheme. It can effectively combine civil engineering with the surrounding ecological environment and human environment, improve the use efficiency of various energy and materials in civil engineering and protect the ecological environment.
Second, the choice of building materials for civil engineering
At present, with the continuous development of civil engineering, the civil engineering building materials on the market are complex and diverse, and many new building materials appear constantly. Therefore, civil engineering construction units should pay attention to purchasing building materials with good environmental protection and safety performance, and try to choose materials that can promote the sustainable development of civil engineering. The safety of civil engineering plays an extremely important role in safeguarding the safety of people's lives and property, especially the earthquake is very destructive to civil engineering. In order to improve the safety and reliability of civil engineering and meet the needs of large-span and high-rise building structures in China at present, most of the steels used in civil engineering develop in the direction of low yield point and high strength, and seismic steel is a typical ecological building material. In order to meet the seismic requirements, the relevant departments have developed SN series special steel, which has higher strength under the condition of roughly the same carbon content and can meet the requirements of large-line energy welding of box-section columns.
In addition, with the continuous development and progress of building technology, higher requirements are put forward for concrete. As an ecological building material, the appearance of high-performance concrete can meet the current situation that traditional concrete is difficult to construct and maintain, improve the working performance of concrete, improve its freeze-thaw durability, enhance its volume stability and prolong its service life in harsh environment.
Third, the construction stage of civil engineering
The construction stage of civil engineering is an important step to ensure the sustainable development of civil engineering. The construction stage of civil engineering can generally be divided into two stages: the preparation stage before construction and the formal implementation of construction. In order to ensure the sustainable development of civil engineering, construction workers should first do all the preparatory work before construction, mainly including the following aspects: First, master the complete construction process, make full preparations for the equipment, funds and various construction technologies needed in the construction site in advance, and ensure that effective measures can be taken in time to solve accidents during construction; The second is to obtain the required legal documents and important basis before construction, and carefully investigate all kinds of raw materials used in construction to ensure the smooth progress of civil construction.
Secondly, the construction personnel must do a good job in the construction stage, so as to ensure the quality of civil engineering. In the process of construction, in order to ensure the scientificity of civil construction, the construction personnel must carry out the construction in strict accordance with the construction drawings. However, according to the actual situation of the construction site, the constructors also need to adjust the construction scheme reasonably from the perspective of sustainable development, track the cost and quality of civil construction in time, and pay attention to correct the engineering projects that do not meet the construction scheme in time.
In addition, for civil contractors and design units, it is necessary to fully investigate and study the surrounding structures such as geological conditions and cultural characteristics of the construction site. When making the construction plan, we should fully consider the original environment around the civil engineering, and make the corresponding construction plan under the premise of adhering to the concept of sustainable development, so as to ensure that the newly-built civil engineering is as harmonious as possible with the surrounding natural environment and human environment. The contractor must make a reasonable construction plan in strict accordance with the specific requirements of the civil engineering design unit and combined with his own work experience, and make a plan to protect the natural environment around the construction site, and constantly optimize the placement of construction pipelines and construction equipment. In order to ensure the implementation of the concept of sustainable development in civil engineering construction, the construction unit must do the following four things.
First of all, the construction unit must pay attention to the treatment of recyclable resources. For some recyclable resources, on the one hand, the construction unit should pay attention to improving the recovery rate of raw materials, establish a recycling system of raw materials at the construction site, disassemble the materials that can be further disassembled, and keep the usable parts, thus reducing the cost of raw materials needed for construction and reducing the cost of construction waste treatment by the construction unit.
Second, the construction unit must strictly control the amount of raw materials. In order to ensure the smooth progress of construction, each construction unit will have a certain amount of inventory, but too much inventory will lead to higher inventory cost and lower capital turnover rate, which is not conducive to the long-term sustainable development of construction units. Therefore, the construction unit must co-ordinate the warehouse storage and procurement, minimize the inventory time of inventory materials, and continuously improve the capital turnover rate of civil construction units.
Third, the construction unit must save electricity. Civil construction takes a long time, involving many types of work and electricity consumption. Therefore, the construction unit must avoid the waste of electricity. In order to improve the utilization rate of electricity, the construction unit can install energy-saving lamps, or install sound control and light control lighting tools to control electricity consumption. At the same time, the construction unit should also reasonably arrange the construction time and various new energy-saving construction equipment.
Fourth, to improve the utilization rate of water resources, the construction unit can reuse wastewater resources through various water treatment equipment or use equipment with small water flow to control water resources, try to control the waste of water resources and reduce the construction cost of civil engineering.
Fourth, conclusion:
With the rapid development of China's national economy, civil engineering construction has ushered in a new development period. In order to implement the concept of sustainable development and promote the long-term sustainable development of civil engineering construction in China, relevant departments must raise awareness and implement the concept of sustainable development throughout the whole process of civil engineering construction.
