China’S Economy

With the rapid development of China's economy and the increasing levels of science, our country's high-rise building height and number of layers is also increasing. Especially in the 21st century, our country develop toward the height of high-rise buildings ever higher, more layers, better equipped, more complete, more advanced technology more economically rational. High-rise building has become a symbol of a modern metropolis. However, due to the high-rise buildings have many people, so relevant norms on its construction and drainage system design and fire safety, reliability and economic practicality of a higher requirement, this requires a high-rise building water supply and drainage system on the technical design more reasonable, economic budget cost savings at the same time to achieve its design function.

Mass concrete is widely being used in the construction field, especially for the foundation of super high-rise building. In the initial stage of pouring completion of mass concrete, lots of heat generated from the cement hydration will lead to a high temperature inside of concrete. When the temperature difference between the inner and outer of concrete exceeds the limited value, thermal stress will be greater than the tensile strength of concrete, which may cause hazardous penetrating cracks of the structure. To ensure the safety and durability of concrete structure, necessary measures should be taken to control the temperature rise and construction quality of concrete. Taking a super high-rise building project as an example, this paper introduces several effective solutions to resolve above problems. The technical measures such as enhancing the concrete quality, controlling temperature rise, strengthening temperature monitoring would be detailed illustrated. Meanwhile, valuable suggestions achieved from this practical project are proposed in order to guide the structural design and on-site construction of similar projects.

In high-rise and ultra-high-rise residential buildings, the drainage systems usually adopt the S-shaped offset pipe joint to avoid collisions of pipelines with beams and columns. However, the flow direction changes at the offset point would significantly affect the drainage capacity of the systems. To better understand the influence of pipe offset joints on the drainage capacity, three different building drainage systems namely YZW 1, YZW 2, and YZW 3 systems, were built up and investigated. YZW 1 system is a standard double-stack drainage system with anti-reflux H-tube joints. YZW 2 and YZW 3 systems were developed from YZW 1 by adding S-shape offset pipe joints on the 4th floor. An extra anti-reflux H-tube joint added 1 m above the offset joint as a measure for improving the drainage capacity differentiates YZW 3 system from YZW 2 system. The pressure fluctuation and water seal losses were adopted as experimental parameters to determine the maximum discharge capacity according to Standard for Capacity Test of Vertical Pipe of the Domestic Residential Drainage System. The experimental results show that the discharge capacity limitation of the drainage system with the offset joint is 6.5 L/s, which is much smaller than 11.0 L/s of the system without the offset joint. In the experiments with the offset joint, the pressure fluctuated fiercely at the position where flow direction changed and caused severe water seal losses of the floor drain and P-shaped trap. An anti-reflux H-tube joint above the original offset joint was observed to relieve the pressure fluctuation as an improvement and the drainage capacity was improved to some extent. The relationships among the maximum discharge rate, pressure fluctuation transients, and water seal losses were discussed. Lastly, a nondimensional analysis was adopted to understand the relationship between water seal losses and pressure limit values under different discharge rates for current test facilities. Practical application: A method has been tested and approved to effectively improve the discharge ability of a building drainage system that includes offset. The application of S-shape-offsets in high-rise building drainage systems can relieve the discharge congestion typically caused by standard pipe offset arrangements.
