关于沉井式污水提升泵房的结构内力计算——以石井镇污水提升泵站为例

Calculation of Structural Internal force of Caisson-type Sewage Lifting pump House——Taking Shijing Town Sewage Lifting Pump Station as an Example

近年来,随着国家对生态环境的重视,环境保护工程在全国大大小小城市如火如荼的进行。污水处理工程自然也不例外,污水提升泵房是污水处理泵站的核心构筑物,也是地面以下深度最深的构筑物。众所周知,场地位置相对紧张(无法大面积开挖放坡),构筑物自身深度较深,且平面尺寸相对较小的构筑物,其支护费用价格不菲,甚至超过了构筑物本身的造价。而在地质情况允许的情况下,无需采用支护的沉井式污水提升泵房则成为一个相对不错的选择。

in recent years,with the national attention to the ecological environment,environmental protection projects in large and small cities in full swing.Sewage treatment engineering is no exception,sewage pumping station is the core structure of sewage treatment pump station,but also the deepest structure below the ground.It is well known that the site position is relatively tight(the slope can not be excavated in a large area),the structure itself is deep,and the plane size is relatively small,the cost of supporting is very expensive,and even exceeds the cost of the structure itself.When geological conditions permit,the caisson-type sewage lifting pump house without supporting becomes a phase.It is a good choice.
