1 Problems in the Sustainable Development of Civil Engineering
1. 1 Design Problems of Sustainable Development of Civil Engineering
The design of civil engineering has three stages, namely, preliminary design, technical design and construction design. In the preliminary design stage, the feasibility analysis, site selection and overall planning of the project are put forward, and the corresponding preliminary plan is formed. For technical design, prepare drawings and descriptions of all relevant parts of the construction project. All materials and materials required for the project shall be determined in the construction design stage. Through the above three links, it can be concluded that sustainable development involves all stages of design. In the preliminary design stage, a comprehensive investigation should be conducted according to the characteristics of the project, so as to make the structure better and use new high-performance materials as much as possible while meeting the functional requirements and investment budget. Within the scope of construction, it is necessary to inspect the surrounding ecological environment and geological and hydrological problems in advance and predict the problems in the follow-up work in advance. In the technical design stage, it is necessary to manage the relationship between departments scientifically, so as to make the cooperation between departments closer, and at the same time, it is necessary to formulate relevant guiding documents. In the stage of construction drawing design, it should be adjusted and revised in time according to the actual situation on site, and the optimization design work should be actively carried out with the help of computer-related design software. Let the overall structure and planning of the project achieve safety, economy and environmental protection.
1.2 Construction of sustainable development of civil engineering
Civil engineering construction is a very complicated and special process, which requires a lot of work to complete. Therefore, the quality of construction management has a direct impact on environmental pollution. In the construction, only the construction management company is familiar with the construction process, can the relevant personnel be trained, managed and deployed reasonably and scientifically. At present, the front-line workers in the civil engineering industry are basically urban and rural migrant workers, and their education level is generally not high, so they can only engage in basic manual labor. However, the staff who graduated from colleges and universities can't meet the actual on-site construction needs because their professional study is out of touch with reality. Therefore, from the whole environment, the comprehensive quality of technicians and managers on site is not high, and these manpower problems will directly lead to interference to the construction site, disrespect to the base environment and increase construction pollution.
1.3 Maintaining the Sustainable Development of Civil Engineering
The process of civil engineering from construction to use to engineering maintenance needs to consume a lot of resources, and at the same time, it will also produce a lot of construction waste and human domestic waste. With the passage of time, the external environment of the building and the frequency of human use will have a great impact on the appearance and structure of the building, thus reducing the service life of the building. Some civil engineering projects were abandoned in advance because of lack of maintenance, which led to the failure of building life. In the use of civil engineering, it is necessary to reasonably reduce man-made energy consumption, improve the use efficiency of corresponding resources, and scientifically guide the use mode. In terms of external environmental impact, we should do a good job in the corrosion of the natural environment to the building, and regularly inspect and maintain the building structure to make the service life of the building longer.
2 Countermeasures for the sustainable development of civil engineering
2. 1 management technology solutions
China's civil engineering construction industry has changed the previous small workshop mode which was mainly manual operation. Joint-stock companies or large group companies have been introduced, and a scientific management system has been established, which has enabled enterprises to pay more attention to civil construction and achieved good results in market operation. Although a large number of advanced management methods have been introduced to make the construction management of civil engineering more professional, there are still many unreasonable phenomena, such as the differences in lifestyle and food culture of management subjects, which will make the introduced management model unacceptable. Therefore, when the new management mode is introduced, it should be modified and adjusted appropriately to make the new management technology and new operation mode more suitable for local civil engineering construction.
2.2 Solutions in the construction stage
In the construction preparation stage, we must first obtain the legal basis for construction and obtain the construction permit, and then prepare all the necessary conditions for construction. Finally, make overall and reasonable arrangements for construction forces and construction sites. In the process of construction, control the construction progress, cost, quality and safety. Personnel should adhere to the training system. All on-site management and operation personnel have been trained in business knowledge and skills, and must obtain corresponding professional and technical titles and hold relevant certificates. Professional workers must be trained and assessed in accordance with the requirements of relevant state regulations, and obtain post certificates and corresponding technical grades. Establish and improve the post responsibility system, each job has a special person in charge, and a special person is responsible for quality tracking.
2.3 Material Utilization Solutions
The realization of technical cleanliness should use as many accessories as possible and use as many ways as possible. In this way, through the reuse of accessories, building materials can be prevented from becoming garbage prematurely. In the engineering production stage, the national standard size can be systematically used for engineering technology design, so that one component can be quickly and conveniently replaced on multiple devices, and the waste caused by replacing the whole device due to the failure of one component can be avoided. The civil engineering industry should encourage the development of remanufacturing engineering technology system, and disassemble, repair and assemble waste and broken materials.
3 abstract
With the progress and development of human society, how to improve human requirements for living space under the condition of limited resources has become an urgent problem to be solved. Future civil engineering not only requires safety, comfort, beauty and durability. People pay more attention to whether the materials, production technology and performance of civil engineering live in harmony with nature.
