一、水塔設計与施工 1. 300m~3钢筋混凝土水塔(不防寒),图号叁标水(71)3028,已经设计完成。本图将取代原标准图水516。本设计的有效水头高度H=20m,24m,28m三种。基础按地基承载力σ=15t/m~2,20t/m~2两种设计。本设计的头部、筒壁、基础等主体结构较以往的设计都进行了改进和提高。其特点是结构型式比较合理、美观、经济。以H=20m,α=15t/m~2为例,新设计图较原标准图水516可以节约混凝土58.11m~3(减少32％),节约钢筋2.8t,(减少23×)。设计中对H=24m, 28m的σ=15t/m~2的基础,还采用了新型的壳体基础
First, the water tower design and construction 1. 300m ~ 3 reinforced concrete water tower (not cold), figure number 叁 standard water (71) 3028, has been designed to complete. This map will replace the original standard map water 516. The effective head height of this design is H=20m, 24m, and 28m. The basic design of the foundation bearing capacity σ=15t/m~2, 20t/m~2. The main structure of the head, cylinder wall, and foundation of this design has been improved and improved over previous designs. Its characteristic is that the structure type is more reasonable, beautiful and economical. Taking H=20m, α=15t/m~2 as an example, the new design diagram can save concrete 58.11m~3 (32% reduction) compared with the original standard figure water 516, and save 2.8t (reduced 23*) steel reinforcement. In the design, the basis of σ=15t/m~2 for H=24m, 28m, and a new type of shell foundation are also adopted.
