Insight - Civil Engineering, Vol.1, No.1, 2018; 790 Views, 76 PDF Downloads

In building engineering, building waterproofing technology is a comprehensive and highly applied engineering science and technology. It is an important part of construction technology. It is important to improve the function of building use and production, quality of life and improve the living environment. Waterproof engineering is a systematic project, which involves the waterproof material, waterproof engineering design, construction technology, the management of the building and other aspects. The task of building waterproofing project is to synthesize all the above factors, to carry out all-round evaluation, select the high-performance waterproof material to meet the requirements, and carry out reliable, durable, reasonable and economical waterproof function engineering design, careful organization, careful construction, maintenance management system to meet the buildings and structures of the waterproof durability, to achieve high quality waterproofi ng and good comprehensive benefi ts. At the same time, waterproof engineering is a demanding professional technology, so the construction of specialization is to ensure that the quality of roof waterproofi ng works the key, if construction operation is not serious, the technology is not enough, and the consequences will inevitably lead to failure of waterproofing works. Quality of waterproofing works the overall quality requirements of building waterproofi ng works are: impermeable to leakage, to ensure smooth drainage, so that the building has a good waterproof and use function. The quality of building waterproofi ng works is superior to waterproofi ng material, waterproof design, waterproof construction and maintenance management.

Insight - Civil Engineering, Vol.1, No.1, 2018; 941 Views, 44 PDF Downloads

Reinforced concrete structure is widely used in housing construction. In the daily work of our construction project, the control of the physical quality of reinforced concrete structural engineering is a key point. Due to the large amount of reinforced concrete works, we often find that the construction workers have not paid enough attention to the thickness control of the reinforced concrete layer in the concrete structure, resulting in diff erent thickness of the steel protective layer and the displacement of the steel. Coupled with the template size deviation and other factors caused by the protective layer of steel does not meet the requirements, and after pouring concrete, and cannot intuitively see its internal structure, and thus bring the hidden quality of the project. In addition to the raw material quality factors, the deflection of the reinforced protective layer of the reinforced concrete structural members directly affects the mechanical properties and durability of the reinforced concrete members, and the direct relationship between the mechanical properties and the durability of the reinforced concrete structures is directly related to the mechanical properties and the durability of the reinforced concrete structures, safety and service life of buildings. Therefore, the parties involved in the construction and the construction should pay enough attention and concern the protective layer of reinforced concrete structures. Here on the author involved in the construction work since the accumulation of experience and experience, the thickness of reinforced concrete structure protective layer of the views of some views for everyone to explore.

Road construction and quality control

by Xiangzheng Cheng, Zhiguo Sun, Fengjuan Chen

Insight - Civil Engineering, Vol.1, No.1, 2018; 755 Views, 51 PDF Downloads

Cement concrete is widely used in civil engineering construction because of its convenient construction, performance can be adjusted according to design, high compressive strength, good durability, and good coordination with steel and other materials. In modern roads and bridges, cement concrete pavement is a common pavement structure. However, due to the construction quality, climatic conditions, and with the rapid growth of heavy cargo vehicles, many cement concrete pavement has been broken, local subsidence and other structural damage; therefore, cement concrete pavement disease, has been aff ected and troubled cement surface use and development. Some opinions are put forward through the analysis and management of some problems in the construction of highland cement concrete pavement.

Research on Crack Control of Mass Concrete Structure

by Honglong Su, Dongtang Duan, Zhibin Lu

Insight - Civil Engineering, Vol.1, No.1, 2018; 1010 Views, 49 PDF Downloads

With the development of economy in our country, the scale of construction has become more and more complicated. This cause the problem of mass concrete cracks in industrial and civil buildings increasingly prominent and become a fairly common problem. The problem of mass cracks in mass concrete is very complex and involves all aspects related to the engineering structure. The control of temperature cracks in mass concrete foundation is related to geotechnical, structural, building materials, construction, environment and other multi-disciplinary. The hydrothermal heat released by the mass concrete in the hardening process which produces a large temperature change, and the resulting of temperature stress is the main factor leading to the occurrence of cracks in the concrete, thus aff ecting the integrity of the structure, water resistance and durability, and become structural hidden dangers. Therefore, the mass concrete in the construction must consider the crack control. The reason and control measures of the temperature cracks of mass concrete are analyzed and summarized. According to the specifi c situation, these measures are applied to the concrete large-scale basic engineering construction, and the material selection, mixing ratio, admixture, construction arrangement and pouring process, conservation and other aspects to take a strict control measures. At the same time the basic position of the internal and external temperature diff erence was monitored. The temperature control measures and monitoring results taken for the basic engineering provide a reference for the construction of similar projects and provide the basis for further theoretical research

The Related Problems in the Construction of the Rainy Season

by Shiyong Zhao, Leping Du, Xiangdong Chen

Insight - Civil Engineering, Vol.1, No.1, 2018; 998 Views, 54 PDF Downloads

With the continuous development of society and the improvement of people's living standard, the construction scale of construction project is increasing and the construction period also increases. In the construction process, the weather changes are often one of the key factors aff ecting the progress and quality of the project. Rainy season construction is the inevitable problem in the construction process, the rainy season construction facing rain, wind, high temperature and other adverse environmental factors, and can directly endanger the production safety, to the enterprise to bring immeasurable losses, so science reasonable organization of construction, to take security technical measures, and actively respond to the rainy season construction of various dangerous situations, to improve the ability to resist risks, to ensure the safety of production, is of great signifi cance. Based on the theory of construction safety management and the characteristics of rainy season, this paper analyzes and controls according the experience and technical characteristics of engineering construction. To ensure the progress and quality of construction and the safety of construction, the principle of minimizing the loss, put forward the corresponding maintenance measures to enhance the safety of the rainy season construction, to enhance the economic interests of enterprises.
