The construction industry is related to people's living, so developers in the construction of all aspects of the security must be strictly controlled and the quality of construction is also the focus of attention among all builders. The materials in construction should be strictly checked. Now most of the construction industry adopts reinforced concrete structure. Therefore, reinforced concrete should be strictly checked when selecting, and its quality directly affects the quality of the whole construction project. It will have a great impact on the construction period and its cost of the whole project, not only the submission of the construction period, but also the safety of people. Therefore, in order to avoid such dangerous situation, the selection of concrete should be strictly checked in order to ensure the quality and to strengthen the optimization of the pouring level of concrete. Thus, the construction quality and economic value can be improved. Based on this, this paper studies the technical difficulties of concrete pouring construction in construction engineering for reference.展开更多

Reasonable planning and construction and the construction of a complete water supply and drainage project can improve the comfort level, avoid problems in the subsequent use of the project, improve the fire safety of the building, reduce losses caused by emergencies such as fire and safeguard the safety of lives and property of residents. This paper analyzes the composition and function of the building water supply and drainage system in our country, and on this basis, makes a detailed analysis of the construction technology of the installation project, hoping to play a reference role.展开更多

Before the construction of foundation, the foundation should be excavated first. In order to prevent soil collapse, the foundation pit needs to be reinforced, among which the safety of deep foundation pit is particularly important. If the supporting structure of deep foundation pit is unqualified or non-standard, it will cause serious consequences. Therefore, the quality and safety of deep foundation pit support structure should attract the attention of relevant construction personnel. According to different geological conditions, formulate appropriate support schemes, and apply the existing construction technology to make the foundation pit stable and safe, which lays a foundation for later construction projects.展开更多
