My company in Changzhou, the first water depth treatment renovation project construction process, the mechanical accelerated clarification method "pool concrete engineering innovative use of bowl shaped hemisphere shell concrete structure construction method", in 2017 won the first batch of Jiangsu Province, the provincial construction method of title.
The difficulties in the construction of bowl shaped thin shell concrete structure are the control of the hemispherical shell bottom, the round shell shell wall and the cylindrical shell wall surface. These construction contents are relatively new topics in the urban water supply industry, and the research work is just beginning.
Changzhou first water advanced treatment project of mechanical acceleration clarifier, top 13.75m, pool for hemispherical shell structure, the bottom radius is 10.5m, the tank body straight wall radius is 11.4m, using C30 concrete, the entire pool analyisis bowl (Figure).
The main principle of bowl shaped hemisphere shell concrete structure construction method is: through the cambered structure construction process, put the line, positioning of the formwork support, installation of formwork and the concrete pouring process, computer simulation and Simulation of construction innovation and optimize the layout, and site construction according to the construction plan, and learn from the successful experience of the past the perfect construction method, construction method developed for such complex arc engineering. The characteristics of this method are as follows: accurate positioning, saving cost, improving the accuracy of bowl shaped hemispherical body arc and the appearance quality of concrete.
The first Changzhou water advanced treatment engineering mechanical accelerated clarification tank construction verification, proved that the method in the whole process of construction is safe, stable, fast and quality control, mechanical accelerated clarifier is currently running, the entire construction process without the occurrence of quality accidents, get all the praise. This method is recommended by Changzhou city construction management center, the provincial housing and urban construction department organized experts to conduct the assessment and evaluation, through the publicity, eventually won the Jiangsu province in 2017 the first batch of Provincial Construction Engineering construction.
Rich experience in construction technical personnel of our company through the daily accumulation, the formation of a bowl shaped hemisphere shell concrete structure construction method, further improve the construction level of the company, and the arc surface of arc shaped structure of the project, to ensure the quality of construction projects, and achieved good economic and social benefits. |
